How Potato Chips Are Made

The Manufacturing Process * 1 When the stump spudes arrive at the plant, they ar examined and tasted for quality. A half(prenominal) dozen or so buckets argon haphazard fill. Some atomic number 18 punched with holes in their cores so that they can be track through and through the cooking address. The potatoes be examined for green edges and blemishes. The pile of defective potatoes is believeed if the clog exceeds a comp alls planned sp atomic number 18ance, the entire truckload can be rejected. * 2 The potatoes die along a car transporter hitto the heterogeneous stages of manufacturing.The conveyor belts atomic number 18 powered by gentle vibrations to keep suspension to a minimum. Destoning and shedding * 3 The potatoes ar loaded into a vertical helical cognise conveyer which dispense withs stones to lapse to the bottom and pushes the potatoes up to a conveyer belt to the automatic pargon machine. After they restrain been peeled, the potatoes are washed with ratty water. Slicing * 4 The potatoes conduct through a revolving impaler/presser that cuts them into paper-thin slices, between 0. 066-0. 072 in (1. 7-1. 85 mm) in thickness. substantial blades produce regular chips while crinkly blades produce ridged potato chips. 5 The slices flux into a stake cold-water wash that unpacks thestarchreleased when the potatoes are cut. Some manufacturers, who market their chips as natural, do not wash the starch off the potatoes. Color treatment * 6 If the potatoes need to be chemically treated to enhance their color, it is done at this stage. The potato slices are immersed in a solution that has been adjusted for pH, hardness, and mineral content. Frying and seasoning * 7 The slices clog up under air jets that re affect excess water as they flow into 40-75 ft (12. 2-23 m) cashboxs filled with crude.The oil temperature is kept at 350-375F (176. 6-190. 5C). Paddles gently push the slices along. As the slices tumble, saltiness is sprinkle d from receptacles positioned above the trough at the rate of about 1. 75 lb (0. 79 kg) of salt to individually 100 lb (45. 4 kg) of chips. The Manufacturing Process * 1 When the potatoes arrive at the plant, they are examined and tasted for quality. A half dozen or so buckets are randomly filled. Some are punched with holes in their cores so that they can be tracked through the cooking process. The potatoes are examined for green edges and blemishes.The pile of defective potatoes is weighed if the weighting exceeds a companys preset allowance, the entire truckload can be rejected. * 2 The potatoes move along aconveyer beltto the various stages of manufacturing. The conveyer belts are powered by gentle vibrations to keep breakage to a minimum. Destoning and peeling * 3 The potatoes are loaded into a vertical helical screw conveyer which allows stones to fall to the bottom and pushes the potatoes up to a conveyer belt to the automatic peeling machine. After they have been peeled, th e potatoes are washed with cold water.Slicing * 4 The potatoes pass through a revolving impaler/presser that cuts them into paper-thin slices, between 0. 066-0. 072 in (1. 7-1. 85 mm) in thickness. Straight blades produce regular chips while rippled blades produce ridged potato chips. * 5 The slices fall into a second cold-water wash that removes thestarchreleased when the potatoes are cut. Some manufacturers, who market their chips as natural, do not wash the starch off the potatoes. Color treatment * 6 If the potatoes need to be chemically treated to enhance their color, it is done at this stage.The potato slices are immersed in a solution that has been adjusted for pH, hardness, and mineral content. Frying and salting * 7 The slices pass under air jets that remove excess water as they flow into 40-75 ft (12. 2-23 m) troughs filled with oil. The oil temperature is kept at 350-375F (176. 6-190. 5C). Paddles gently push the slices along. As the slices tumble, salt is sprinkled from receptacles positioned above the trough at the rate of about 1. 75 lb (0. 79 kg) of salt to each 100 lb (45. 4 kg) of chips. Potatoes arrive daily at manufacturing plants.After they are resisted for quality, they are stored at a constant temperature unfil they are affect into potato chips. Some manufacturers treat the potatoes with chemicals to improve the color of the last(a) product. To shake the chips, potatoes are fried in either corn oil, cottonseed oil, or a blend of vegetable oils. Flake salt rather than quartz salt is use to season the chips. * 8 Potato chips that are to be flavored pass through a drum filled with the desired small-grained seasonings. cooling system and sorting * 9 At the end of the trough, a cable work belt pulls out the hot chips.As the chips move along the participation conveyer belt, excess oil is drained off and the chips begin to cool. They so move under an optical sorter that picks out any burnt slices and removes them with puffs of air. b ox * 10 The chips are conveyed to a packaging machine with a scale. As the pre-set weight of chips is measured, a metal detector checks the chips erst more for any hostile matter such as metal pieces that could have go with the potatoes or been picked up in the frying process. * 11 The base of operationss flow deck from a roll. A central processing unit (CPU) code on the clutch tells the machine how many chips should be released into the bag.As the bag forms, (heat seals the baksheesh of the filled bag and seals the bottom of the next bag simultaneously) gates open and allow the comely amount of chips to fall into the bag. * 12 The filling process mustiness be accomplished without letting anoverabundanceof air into the bag, while in any case preventing the chips from breaking. numerous manufacturers usenitrogento fill the space in the bags. The shut bags are conveyed to a collator and hand-packed into cartons. * 13 Some companies pack potato chips in I O cans of various sizes. The chips flow down a start into the cans.Workers weigh each can, make any necessary adjustments, and attach a top to the can. Quality Control Taste samples are made from each muckle throughout the manufacturing process, usually at a rate of once per hour. The tasters check the chips for salt, seasoning, moisture, color, and overall flavor. Color is compared to charts that show acceptable chip colors. Preventing breakage is a primary goal for potato chip manufacturers. Companies have installed safeguards at various points in the manufacturing process to decrease the chances for breakage. The heights that chips fall from conveyer belts to fryers have been decreased.Plastic conveyer belts have been replaced with wide mesh stainless marque belts. These allow only the larger chips to travel to the fryers and the smaller potato slivers to fall through the mesh. Byproducts/Waste Rejected potatoes and peelings are sent to farms to be used as animal feed. The starch that is remove d in the rinsing process is change to a starch processor. The Future Potato chips show no score of declining in popularity. However, the publics increased demand for low-fat foods has put manufacturers on a fast-flying track to produce a reduced-calorie chip that pleases the palate as well.In the late 1990s, Proctor and Gamble introduced olestra, a fat substitute that was existence test-marketed in a variety of products, including potato chips. Food technicians are victimization computer programs to design a crunchier chip. Upper- and lower-wave forms are fed into the computer at varying amplitudes, frequencies, and phases. The computer then spits out the corresponding models. Researchers are likewise working on genetically engineered potatoes with less plunder content since it is the lollipop that produces brown spots on chips. Potatoes arrive daily at manufacturing plants.After they are checked for quality, they are stored at a constant temperature unfil they are processed into potato chips. Some manufacturers treat the potatoes with chemicals to improve the color of the final product. To make the chips, potatoes are fried in either corn oil, cottonseed oil, or a blend of vegetable oils. Flake salt rather than crystal salt is used to season the chips. * 8 Potato chips that are to be flavored pass through a drum filled with the desired powdered seasonings. Cooling and sorting * 9 At the end of the trough, a wire mesh belt pulls out the hot chips.As the chips move along the mesh conveyer belt, excess oil is drained off and the chips begin to cool. They then move under an optical sorter that picks out any burnt slices and removes them with puffs of air. Packaging * 10 The chips are conveyed to a packaging machine with a scale. As the pre-set weight of chips is measured, a metal detector checks the chips once more for any foreign matter such as metal pieces that could have come with the potatoes or been picked up in the frying process. * 11 The bags flow down from a roll. A central processing unit (CPU) code on the bag tells the machine how many chips should be released into the bag.As the bag forms, (heat seals the top of the filled bag and seals the bottom of the next bag simultaneously) gates open and allow the proper amount of chips to fall into the bag. * 12 The filling process must be accomplished without letting anoverabundanceof air into the bag, while excessively preventing the chips from breaking. Many manufacturers usenitrogento fill the space in the bags. The sealed bags are conveyed to a collator and hand-packed into cartons. * 13 Some companies pack potato chips in I O cans of various sizes. The chips flow down a chute into the cans.Workers weigh each can, make any necessary adjustments, and attach a top to the can.
