0:01ready to explode with
0:02curiosity in this video we're about to
0:05open some top secret doors to the world
0:07of fireworks and firecrackers things you
0:09never even knew existed stick around and
0:12you'll see how a simple blend of
0:14gunpowder turns into the magic behind
0:16the brightest blasts you'll get the
0:18lowdown on the wild history behind their
0:20creation and the unusual secrets of
0:23Master pyro technicians this segment
0:25will get your heart pounding faster
0:27trust me watch till the end cuz the best
0:30part is still ahead stay with us all the
0:32way through and you'll find out
0:33something that'll totally flip your
0:34perspective don't miss
0:38out firecrackers they're the more
0:41hot-headed guys in this family their
0:43main trick it's all about the sound not
0:45the show sure they're simpler in design
0:48but they deliver the same kind of magic
0:50noise and pure adrenaline like fireworks
0:54firecrackers use black powder as their
0:56base but the approach here is a bit more
0:58straightforward the key is nailing the
1:01right balance to get a powerful boom
1:03without any extra fancy effects
1:06typically a firecracker contains a black
1:08powder mixture a casing and a fuse we'll
1:12get into what's inside later but for now
1:14let's talk about the casing it's usually
1:17a paper or cardboard cylinder that holds
1:19everything together the materials got to
1:21be strong enough to hold off the blast
1:23till the big moment but not so tough
1:25that it creates dangerous shrapnel the
1:28fuse is the most critical part it sets
1:30off the entire explosive process it
1:33could be a thin cotton wick soaked in
1:35chemicals or more modern ignition
1:38systems how are firecrackers made all
1:41the ingredients for the black powder mix
1:43are measured out with serious Precision
1:45then blend it to get the perfect
1:47consistency accuracy is huge here just a
1:51little extra salt peter can make the
1:53explosion go wild too little and the
1:55firecracker won't ignite at all paper or
1:58cardboard tubes are cut to the needed
2:00length then carefully loaded with the
2:02black powder mixture these casings
2:04typically have sealed ends to build up
2:06just the right pressure for the
2:08explosion at the top of the firecracker
2:10a small hole is made for the fuse the
2:12fuse is inserted and held in place with
2:15glue or a special
2:17sealant the bottom and top edges of the
2:19firecracker are sealed tightly often
2:21using glue or heat bonding this ensures
2:24safe storage and
2:25transportation next the firecrackers
2:28undergo careful testing manufacturers
2:31check the sound level ignition speed and
2:33quality of the explosion not all
2:35firecrackers are created equal cheap
2:38ones often have uneven filling weaker
2:40sound and a bigger risk of misfiring
2:43they use lower quality materials like
2:45plain paper instead of sturdier
2:49cardboard highquality firecracker
2:51casings are made from sturdy yet
2:54lightweight material the black powder
2:56mixture inside is evenly distributed for
2:59a consistent effect effect the fuses
3:01have a precise burn time to give you
3:02enough seconds to back off to a safe
3:04distance making firecrackers is no joke
3:07pyrot Technics plants follow strict
3:09safety rules workers operate in small
3:12Crews wear anti-static clothing and
3:15handle only minimal amounts of mixture
3:17at any one time to reduce the risk of
3:19accidental
3:21explosions why are firecrackers so loud
3:24this question comes up a lot the deal is
3:27a firecracker explosion isn't just a
3:29chemical reaction it's a massive release
3:32of energy in a confined space when the
3:34powder Burns it releases hot gases that
3:37expand super fast creating a powerful
3:40shock wave and since the casing is
3:41tightly packed that wave comes with the
3:43trademark boom sound we all
3:49know the word firecracker comes from the
3:52French petar meaning a blast like
3:55fireworks firecrackers Trace their Roots
3:58back to China initially they were used
4:01to scare off evil spirits and only later
4:03did they become a popular form of
4:05entertainment today fir crackers are an
4:08essential part of many celebrations and
4:10festivals around the globe but their
4:12history shows that even the simplest
4:14things can have deep roots and a
4:16fascinating Evolution so the next time
4:18you hear that familiar bang remember
4:21just how much skill history and
4:23technique is packed into each tiny
4:27firecracker when it comes to making fire
4:29fireworks you also start by mixing
4:31gunpowder with other components if you
4:34think of gunpowder as the engine of the
4:36firework then the other materials are
4:38the artists who create that explosion of
4:40color light and shape to get bright
4:43Sparks you need metal powders like
4:46aluminum magnesium and titanium shavings
4:49for vivid colors you rely on metal salts
4:52such as strontium barium copper and
4:54sodium to boost the energy of the blast
4:57you add ingredients like potassium
4:59nitrate perchlorates and charcoal these
5:01act as oxidizers and fuels and to hold
5:04it all together you use binding agents
5:07like water soluble glues each component
5:10is first ground into the finest possible
5:12powder picture shining metal particles
5:14dancing in the light as the master
5:16prepares them for blending these powders
5:19are so lightweight it's almost as if
5:21they're suspended in midair like some
5:23kind of magical dust the most important
5:26step starts when the ingredients go into
5:28a mill filled with ceramic or wooden
5:30balls these balls rotate gently grinding
5:33the mix into a perfectly uniform blend
5:35there's a soft rustle and a light
5:37tapping sound kind of a subtle Rhythm
5:40reminding you that a future burst of
5:41colors is being born as for mixing the
5:44ingredients by hand at traditional
5:47production sites this step is done with
5:49great care and reverence Specialists
5:51slowly and carefully blend the
5:53ingredients with wooden or copper
5:55paddles why so slow because even a
5:57single stray spark could set the the
5:59whole thing off the mixture looks like a
6:02shimmering sand where each component has
6:05its role to play to avoid accidental
6:07explosions the mixture is often
6:09moistened water doesn't just make the
6:12process safer it adds a sort of
6:14mysterious Alchemy as gunpowder and
6:16colorant form tiny
6:18granules the smallest mistake can cause
6:21a tragedy you know what pyot Technic
6:23Masters do before they start working
6:26they remove all metal objects even
6:28wedding rings to prevent Sparks in many
6:31Labs cell phones are strictly forbidden
6:33and employees wear anti-static clothing
6:36even the air matters conditions are kept
6:38humid enough so that mixes don't dry out
6:40and become dangerously volatile before
6:43packing the mixture into the casing the
6:45Masters test how it burns a small sample
6:48is ignited and everyone holds their
6:50breath is that the perfect shade of blue
6:53are the Sparks bright enough it's like a
6:55dress rehearsal before the Big Show
7:00creating shapes and colors that's the
7:02coolest part of production want a heart
7:05or a star in the sky it all depends on
7:07how the stars are arranged these are
7:10tiny pellets with a special composition
7:12where did those brilliant Reds greens
7:14and blues come from all thanks to
7:17chemical compounds for instance barium
7:20makes green strontium makes red and
7:22copper makes blue once all the
7:24components are prepped the next crucial
7:26step is filling the casing Where The
7:28Heart of the future firework is born
7:31it's right here that the explosive mix
7:33and colorant become a finished product
7:35capable of painting the night sky in
7:37every color of the
7:40rainbow the casing is a shell that holds
7:43all the fireworks Parts together it's
7:46made from special materials that can
7:48handle high pressure and heat yet remain
7:50light enough to shoot into the sky
7:52cylindrical shapes are perfect for
7:54forming sharp patterns like Rings
7:56chrysanthemums or peonies while spheric
7:59shells create symmetrical
8:01three-dimensional effects like a glowing
8:03orb exploding into hundreds of Sparks
8:06The Filling process is super important
8:08because the exact placement of
8:09components ensures the desired effect
8:12let's break it down step by
8:14step first you take cylindrical or
8:17spherical shells usually made of
8:19cardboard plastic or specially treated
8:22paper with fire resistant properties
8:24spars typically come in two hes that
8:27will be joined later it's crucial that
8:29the casing is airtight that guarantees
8:32the explosion happens at the right
8:33moment with the right intensity the
8:35black powder charge acting as the main
8:37engine sits at the center it's
8:39responsible for propelling the firework
8:41Skyward and making sure it explodes
8:44properly around that charge the
8:46colorance and special effect mixtures
8:48are arranged each tiny star element is
8:51placed by hand or using special machines
8:54these stars are what we call the pellets
8:57that burn in the sky for spherical
9:00shells these stars are placed evenly so
9:03that when it explodes it forms a perfect
9:05sphere of light in cylindrical shells
9:08charges are often laid in layers or
9:10formed into specific patterns depending
9:13on the planned Effect one standard
9:15spherical firework can hold about 200 to
9:18300 pellets large multi-layer shells
9:22might have over 1,000 of them to ensure
9:25the firework explodes at the right time
9:27a time delay fuse is added a small tube
9:30filled with a slower burning composition
9:33this timer connects to the main charge
9:35providing a delay between the Rockets
9:37launch and the burst in the
9:41sky after all elements are in place
9:43they're secured with a special paste or
9:45paper spacers this keeps every component
9:48locked in position during the launch the
9:50casing might then be wound tightly with
9:52string or glued for extra rigidity
9:55crafting one large professional grade
9:57firework can take up to 4 hours
10:00considering all the careful assembly and
10:01testing for a massive show with several
10:04thousand shells pyrot technicians might
10:06work for a few months
10:08straight the spherical shape is the
10:11classic standard in pyot Technics giving
10:13an even spread of stars and creating
10:15that perfect circular effect filling
10:18such a shell requires even more skill
10:21each star is placed by hand around the
10:23central charge it's all on the Master's
10:26shoulders how the components are
10:28arranged will Define how the explosion
10:30looks for example to create a smiley
10:33face in the sky the pellets are laid out
10:35in the shape of a face when the powder
10:38ignites those pellets spread out just
10:40right forming the intended pattern every
10:43year over 200,000 short tons of
10:46fireworks are produced worldwide China
10:49is the leader here accounting for about
10:5190% of the global output for major
10:53holidays like Independence Day in the
10:55United States or New Year's Eve in
10:57Sydney up to 10,000 thousand separate
11:00fireworks might be launched in a single
11:02night such a display can last over 20
11:05minutes and sometimes costs as much as
11:07$5
11:08million despite the beauty of fireworks
11:11safety stats are pretty alarming in the
11:13United States each year up to 10,000
11:16injuries are reported due to improper
11:18use of pyrot Technics with about 70% of
11:21the injured being young people under 20
11:23years
11:25old sell 100 million pairs of shoes in a
11:28year what kind of of production can pull
11:30that off you won't believe it but Crocs
11:32did just that today we're going to walk
11:35the path of the world's lightest
11:36Footwear from a polymer bead to a cult
11:39favorite and from that cult we'll move
11:42on to recycling these shoes Crocs was
11:44founded in 2002 and their products
11:46instantly took over the
11:49world the manufacturing process of Crocs
11:51is pretty complex it all starts with the
11:54raw materials they're the key to Croc's
11:56success the material they're made of is
11:58called croslite a patented foam resin
12:01that provides lightness comfort and
12:03durability it's not just rubber shoes
12:06like many people think but a special
12:08closed cell foam material crosslite is a
12:11type of ethylene vinyl acetate a polymer
12:14material that boasts water resistance
12:16cushioning properties and high wear
12:18resistance polymers for cross light are
12:21produced from oil or natural gas which
12:23are processed into polyethylene large
12:26chemical Enterprises located in Asia
12:28Europe and the USA Supply this raw
12:31material to Crocs factories the raw
12:33material is transported in the form of
12:35pellets they're easily shipped in large
12:38containers and stored in dry conditions
12:40until production Begins the main Crocs
12:43manufacturing factories are located in
12:45Asia Vietnam China and Indonesia these
12:48countries have access to Affordable
12:50labor large volumes of raw materials and
12:52robust
12:54Logistics the name Crocs comes from the
12:56word crocodile because these animals can
12:59live both in water and on land just like
13:01these shoes now let's head over to the
13:04production line bro check out how these
13:06guys load the pellets into a special
13:08machine where they're heated to high
13:09temperatures it's seriously hot the
13:12melting temperature of the material
13:14reaches 400° F the material melts and
13:17becomes liquid resembling thick cream
13:20the liquid polymer is poured into
13:22special molds that shape the shoes the
13:24molds are subjected to high pressure
13:26ensuring all the details are filled
13:28tightly excess polymer oozes out under
13:31pressure from the mold kind of like
13:33creme brulee if it weren't for the smell
13:35in the factory you'd be tempted to take
13:36a bite right but it's definitely not
13:39something
13:40edible as it cools down the material
13:43expands creating cross light's unique
13:45closed cell foam structure this provides
13:48lightness elasticity and softness water
13:51resistance and antibacterial properties
13:55the shoes weigh on average only about 5
13:57to 7 o confess it who's going to run off
14:00to weigh their Crocs after watching this
14:01video but let's keep going bro shoes
14:04made from these amazing pellets don't
14:06absorb odors and are easy to clean but
14:09all this happens after they're taken out
14:11of the mold that's when the excess
14:13material is trimmed off and the edges
14:16are smoothed look how quickly and
14:18precisely these guys work the surface is
14:21polished to avoid burs or roughness it
14:24takes less than 5 minutes to produce one
14:26pair of Crocs
14:29after trimming the excess material from
14:31the mold the cut edges are treated with
14:33grinding machines this is done to remove
14:35sharp edges burs or irregularities left
14:38after trimming first they use abrasive
14:41belts or discs with medium grit which
14:44quickly remove large irregularities
14:46rotating grinding tools allow the edges
14:48to be processed evenly and replicate the
14:51shape of the sole and the upper part of
14:53the Croc then the workers move on to
14:55fine polishing to ensure the surface is
14:58soft and smooth smooth they use fine
15:00grit abrasives like sanding sponges this
15:03stage removes microscopic roughness that
15:05could cause discomfort when wearing for
15:08particularly sensitive areas like the
15:10edges of the ventilation holes they use
15:12hand tools like sanding sponges or
15:14polishing pads hand polishing guarantees
15:17the absence of even the smallest Burrs
15:20in the US the military uses them as
15:22shower shoes because they're
15:24waterresistant and dry
15:27quickly other elements are added to the
15:29finished shoes namely straps and jbits
15:33the straps for securing are attached
15:35separately they're made from the same
15:36material or from more rigid polymers
15:39rivets are installed on the straps
15:41allowing them to move what kind of jbits
15:44do you have jbits are decorative
15:46accessories that attach to the
15:48ventilation holes of Crocs they allow
15:50you to personalize your shoes by adding
15:52elements that reflect your individuality
15:55Hobbies or even mood the idea for
15:58decorating rocks came about in 2005 it
16:01was invented by Sher shitsky a mom who
16:05together with her kids came up with a
16:06way to Adorn Crocs with tiny plastic
16:09charms let's all write in the comments
16:12thank you
16:13Sherry Sherry used regular decorative
16:15buttons that her kids attached to the
16:17ventilation holes on their Crocs the
16:20idea was so popular among friends and
16:22acquaintances that it eventually turned
16:24into a full-fledged business in 2006 the
16:28Crocs brand bought bought the idea for
16:29$10 million adding jibbit to their
16:32official product
16:33lineup jibbit are small decorative
16:36elements made from soft plastic or
16:38silicone they have unique shapes and a
16:40special fastening mechanism jbits can be
16:42in the form of symbols emojis logos
16:45favorite movie characters animals plants
16:48inscriptions and so on the back of the
16:50jibit has a small stem or pin that fits
16:53into the ventilation hole of the Crocs
16:55thanks to the material's elasticity the
16:58jibit easily inserts and holds very
17:00securely first designers create sketches
17:03of future charms these can be popular
17:05symbols current memes or seasonal themes
17:08for example snowmen in Winter or
17:11sunflowers in summer after the design is
17:14approved three-dimensional models are
17:16created which are used to form
17:17production molds liquid plastic or
17:20silicone is poured into molds with
17:22detailed designs after cooling the
17:24material solidifies retaining the shape
17:27of the charm simultaneous ly the back
17:29fastening part is formed ensuring a
17:31secure connection with the Crocs in 2021
17:35a unique jibbitz was sold at auction for
17:37$10,000 it was made of gold and adorned
17:40with
17:41diamonds as for coloring and applying
17:43patterns various techniques are used
17:45here as you can see color is added at
17:47the stage of melting the pellets so that
17:49the color is evenly distributed
17:51throughout the structure and to create
17:53print they use laser engraving or
17:55printing techniques each pair undergos
17:57quality checks for compliance with shape
18:00color and absence of defects if defects
18:03are found such pairs are discarded or
18:05sent for recycling and that's the end of
18:07the production cycle the finished Crocs
18:10are packed into boxes and transported by
18:12sea containers or by air to warehouses
18:14around the
18:15world Crocs are comfortable shoes but
18:18they present an environmental challenge
18:21the cross- light material isn't a
18:22traditional plastic at the same time the
18:25Crocs brand is making efforts to make
18:27its products more eco-friendly and to
18:29find effective ways to reuse old shoes
18:32the patented foam material doesn't
18:34decompose naturally so if you throw out
18:36old Crocs they can remain in landfills
18:38for decades crosslite doesn't lend
18:41itself to standard plastic recycling
18:43methods due to its unique chemical
18:45structure recycling requires special
18:47technologies that most waste processing
18:50facilities don't have you get it bro
18:52they invented a unique durable material
18:55but now the problem is what to do with
18:57it afterward in the past Crocs
19:00implemented a program to collect old
19:02Crocs they disinfected refurbished and
19:05passed them on to people in developing
19:07countries so we're cluttering up not our
19:10own country but those who don't have a
19:12choice controversial idea huh that's why
19:15the program was discontinued but it
19:17inspired the creation of new Eco
19:20initiatives in some Croc stores you can
19:23leave your old shoes which are sent for
19:25Research into reuse or for conversion
19:28into energy resources today old Crocs
19:31are sometimes used to obtain energy
19:33through the process of pyrolysis
19:35crosslite is burned in special furnaces
19:38and the energy obtained is used for heat
19:40or electricity production admit it
19:42that's a pretty good look also after
19:45shredding old Crocs can serve as the
19:47basis for new materials such as rubber
19:49Coatings for playgrounds insulation
19:52material or as construction or
19:54decorative
19:56elements sushi that rival top tier
19:59restaurants ready in just minutes
20:01imagine machines crafting thousands of
20:04perfect rolls every hour with rice of
20:06flawless consistency forming the base of
20:09nigeri we're here to unveil the secrets
20:11behind automated systems that transform
20:13tons of raw ingredients into true
20:16culinary masterpieces curious about how
20:18Sushi is made for supermarkets and
20:20restaurants stay tuned to find
20:23out it all starts with rice as the
20:26Cornerstone of sushi cooking it properly
20:29is one of the most crucial steps in
20:31large sushi restaurants and production
20:33facilities high-capacity rice cookers
20:35are used capable of handling between 22
20:39and 66 lbs of rice per cycle these
20:42cookers ensure precise control over
20:44temperature and cooking time producing
20:46rice with the perfect consistency every
20:48time the second key ingredient is fish
20:52in the United States most Sushi
20:54operations rely on frozen fish
20:56especially salmon and tuna to meet FDA
20:59requirements for parasite destruction
21:01rapid thawing systems maintain strict
21:04temperature control preserving the
21:05fish's texture and flavor these systems
21:08can defrost up to 1,000 lbs of fish per
21:11hour fish slicing machines are equally
21:14impressive in their efficiency some
21:16models can cut up to 1,000 pieces of
21:18fish per hour with remarkable Precision
21:21automated blades adjust slice thickness
21:24allowing for customization depending on
21:26whether the fish is destined for njeri
21:28rolls or Sashimi fetting machines also
21:32play a vital role expertly processing
21:34fish to reduce waste and ensure uniform
21:37pieces these machines can handle up to
21:40200 fish per hour significantly reducing
21:42prep time compared to manual
21:45labor vegetables like cucumber avocado
21:49daon radish and others require careful
21:52preparation modern vegetable washing
21:54machines can handle up to 660 lb of
21:57produce per hour
21:59these machines effectively remove soil
22:01and contaminants ensuring sanitary
22:03conditions are maintained throughout the
22:04production
22:06process vegetable slicing machines allow
22:08for Rapid cutting into thin strips cubes
22:11or slices for instance thin cucumber and
22:15avocado strips are essential for rolls
22:18these machines can process up to 220 lbs
22:21of vegetables per hour producing
22:24perfectly uniform pieces that contribute
22:26to Sushi's consistent appearance once
22:29prepared vegetables are stored in
22:30specialized Refrigeration units with
22:33automatic humidity control to keep them
22:35fresh throughout the day this is
22:37particularly important for avocado which
22:39oxidizes quickly and can change color if
22:42not properly stored Nori or pressed
22:45seaweed usually requires minimal
22:47preparation but specific protocols help
22:49keep it fresh and crispy large Sushi
22:52production facilities often use special
22:54low humidity storage containers to
22:56prevent Nori from becoming soggy for use
22:59some automated Sushi making systems even
23:02include machines that cut Nori to the
23:04exact size needed for various types of
23:05sushi streamlining the process
23:08further infrared and Optical scanners
23:11are used to check the quality and
23:13freshness of ingredients for example
23:16these scanners can assess the freshness
23:17of fish by measuring moisture levels and
23:19the color of the flesh helping to
23:22identify substandard products before
23:24they reach the production line all
23:26ingredients are stored at optimal
23:28temperature
23:29for instance fish is kept between 30 and
23:3128° F to maintain freshness automated
23:35refrigeration systems Monitor and record
23:38temperature data in real time ensuring
23:41consistent storage conditions the
23:43automation of ingredient preparation
23:46significantly reduces the time needed to
23:48ready products for use thanks to these
23:50Technologies a large sushi restaurant or
23:53production facility can process up to
23:554,000 lb of ingredients daily guarantee
23:58ing both freshness and uniformity in
24:00every Sushi portion this not only Cuts
24:03labor costs but also improves sanitary
24:05conditions by minimizing direct human
24:07contact with
24:08food have you ever tried making sushi at
24:11home I have I bought the fish cream
24:14cheese even a special rolling mat
24:17watched a few YouTube videos feeling
24:20pretty confident after a few hours of
24:22trying to put that Newfound knowledge
24:24into practice the result let's just say
24:27it was very home made you know what that
24:29means delicious on the inside but
24:32hilariously amateur on the outside and
24:34don't forget the hours spent on it what
24:37did I learn never again I'll stick to
24:40ordering Sushi delivery it's my true
24:45love before cooking rice needs to be
24:48thoroughly rinsed to remove excess
24:50starch which can make it overly sticky
24:52industrial rice washing machines can
24:54process between 110 and 220 lb of rice
24:58per hour some models allow for
25:00adjustments in the intensity and number
25:02of rinse Cycles to achieve the perfect
25:04texture each rinse cycle takes about 3
25:07to 5 minutes which is significantly
25:09faster than manual washing these
25:12machines also regulate water usage
25:14helping to minimize
25:18waste after washing the rice moves to
25:20specialized industrial rice cookers
25:23which automatically control the
25:24temperature and cooking time to ensure
25:26the ideal consistency
25:29a single cooking cycle lasts between 45
25:32minutes and 1 hour depending on the rice
25:34volume and machine capacity the cooker
25:37carefully manages the heating process
25:39starting with cold water and gradually
25:41warming it allowing the rice to cook
25:44evenly most rice cookers operate within
25:46a temperature range of 194 to 210° F
25:51once cooking is complete some models can
25:54keep the rice warm for several hours
25:56ensuring it remains ready for use
25:57throughout the day without compromising
26:00[Music]
26:01quality after cooking the rice must be
26:04seasoned with a special mixture of rice
26:06vinegar sugar and salt which gives it
26:08the distinctive flavor needed for sushi
26:10on Industrial kitchens this step is also
26:13automated to ensure a consistent taste
26:15in every portion there are specialized
26:18devices that automatically distribute
26:20rice vinegar adjusting the amount based
26:22on the weight of the rice for instance
26:24approximately 17 o of vinegar are
26:26typically used for 22 2 lbs of rice the
26:29rice is then mixed using specialized
26:31mixers that cool it and maintain the
26:33optimal temperature to prevent excessive
26:35clumping the rice is usually cooled to
26:38around 100° F which is an ideal
26:41temperature for forming Sushi once
26:43prepared the rice is kept warm in
26:45specialized containers that
26:47automatically regulate the temperature
26:48to prevent it from spoiling too
26:53quickly the sushi shaping stage is the
26:56final step in the production process in
26:58large-scale American facilities that
27:00specialize in mass-producing sushi for
27:03supermarkets restaurants or delivery
27:05services this process is highly
27:08automated this automation ensures High
27:11productivity consistent quality and
27:14precise portioning almost like
27:16modern-day Samurai the process begins
27:19with preparing the rice bases that serve
27:21as the foundation for nigiri rolls and
27:24Maki sui nigiri machines can
27:27automatically form R balls of uniform
27:29weight and size ensuring accuracy in
27:32every serving for instance automated
27:35njeri machines can produce rice balls
27:37weighing 10 to 15 G each which is the
27:40ideal weight for easy consumption some
27:42of the latest models can produce up to
27:444,000 pieces of njeri per hour these
27:48machines guarantee uniform shapes
27:50reducing the risk of sushi falling apart
27:52during serving or packaging additionally
27:55they provide perfect rice compression
27:57ensuring that each piece has a
27:58consistent
28:03density for various types of rolls such
28:05as futomaki uramaki and hosomaki
28:09specialized machines are used to
28:10automate the rolling process these
28:12machines distribute rice evenly over a
28:14sheet of nori apply the filling and then
28:17roll it all together the system is
28:19calibrated to ensure the rice covers the
28:21Nori evenly with a thickness of about 5
28:24to 8 mm depending on the type of roll
28:28the machines can also automatically add
28:30fillings to the center of the Roll
28:32precisely controlling both the quantity
28:34and placement the amount of fish
28:36vegetables or avocado can be adjusted to
28:39within a gram for each serving once the
28:42roll is formed cutting machines take
28:44over these machines are equipped with
28:46ultra sharp blades that slice the roll
28:48into six to eight pieces without
28:50squashing or deforming it the system
28:53adjusts the thickness of each slice to
28:54ensure uniform height typically around 1
28:57in per piece
28:58some machines even feature a
29:00self-cleaning function for the blades
29:02after each roll preventing rice buildup
29:04and ensuring a perfect cut every time
29:07now that's the kind of knife I'd love to
29:09have at home
