Aseptic packaging equipment and food production

Aseptic packaged food refers to the food that is aseptic before packaging and packaged with aseptic materials, and does not need to be reheated for sterilization International food hygiene has strict regulations on food preservatives, while food tends to be low sugar and low salt, while general food itself has poor storage Therefore, aseptic packaged food has developed rapidly in the world, which can not only maintain food flavor, but also save energy The proportion of aseptic packaged food in the world is increasing year by year, which promotes the corresponding rapid development of packaging materials and packaging machinery and equipment Aseptic packaging equipment of food aseptic packaging equipment of food consists of sterilization device, aseptic filling packaging machine or aseptic packaging machine, cleaning device of food, aseptic room, etc The liquid food such as milk is sterilized by high temperature and short-term (ultra-high temperature and instantaneous) sterilization before aseptic filling The heating methods include direct method and indirect method The direct heating method is generally used for the sterilization of processed dairy products, tomato sauce and concentrated fruit juice, and the equipment which does not make food coking is adopted Japan has developed equipment for continuous and long-term sterilization of high viscosity and fluidity food and uth sterilization equipment for direct sterilization of high viscosity and fluidity food from 3000cp (viscosity) to 200000cp The high viscosity and fluidity food and steam are directly mixed at high temperature (100 ℃ ~ 150 ℃) and heated uniformly in an instant, and evaporated water in the vacuum system is cooled rapidly The aseptic packaging of sliced ham The surface microorganism of sliced ham is killed by ultrasonic sterilization and cleaning device After washing the surface of sirloin ham packed with fiber casings with alkaline surfactant, it was sterilized with sodium hypochlorite to completely kill the bacteria New aseptic packaging machine aseptic filling packaging machine for user packaging Dole aseptic packaging machine in the United States, the packaging materials are metal

hot air drying; LigulPak aseptic packaging machine in the US, using low containers, packaging milk and fruit juice drinks, spray 1ml0.1%H2O2 in the forming paper container, UV sterilization and hot air drying PREA aseptic packaging machine in France, the packaging material is multi-layer plastic, packaging fruit juice drinks, pudding, coffee milk, etc., to peel the multi-layer slice and use the aseptic inner surface as the container France's thim onner equipment, packaging materials are rolled plastic film, packaging milk sauce, juice drinks, packaging materials are sterilized with ethanol and UV Hassis and hamba aseptic packaging machine in Germany, the packaging material is multilayer plastic, packaging sour cheese, pudding, juice drinks, snacks, using 130 ℃ ~ 150 ℃ high temperature and steam sterilization or using high-performance ultraviolet sterilization device to sterilize the packaging material The new aseptic filling packaging machine for user packaging The sterilization of packaging materials and containers is replaced by hot air, steam, ethanol, UV and other sterilization methods by the original H2O2 Ercaconoffast packaging machine developed in France and the United States squeezes the packaging materials into PE / PP / PE / PVDC / PE multilayer sheets and peels out two layers The remaining forming sterile sheets, filling, sealing and packaging materials do not need H2O2 sterilization (PE: polyethylene, PP: polypropylene, PVDC: polydichloroethylene) vacuum packaging machine and gas filling packaging machine for aseptic packaging of meat processing products, dairy products and rice cakes Japan has also developed a serial aseptic packaging system, which is jointly operated by slicer, weighing machine and aseptic packaging machine The new aseptic filling and packaging machine for business the new aseptic filling and packaging machine for business is developed internationally Its mechanical characteristics and microbiological sterilization methods are as follows: asepak aseptic filling and packaging machine in the United States, packaging materials are plastic tubes, packaging meat, condiments, tomato paste, no H2O2, UV sterilization, using filling tubes, food and packaging materials for sterilization, aseptic filling and packaging combination Homework Eranrica and Sholle aseptic packing machines in the United States are used for packing vegetables, ketchup, juice drinks, yoghurt and sauced food (peanut butter, etc.), and the packing material is 150um thick LDPE / PVDC / LPPE / PVDC / LDPE / EVA LDPE extruded film or aluminum boiled pet bag (LDPE: low density polyethylene, EVA: vinyl acetate copolymer, pet: polyester) The R-line sterilizer with a capacity of 114-1140 liters was used for 2 minutes or 80% ethanol sterilization Titomanzini aseptic filling packaging machine of Italy, the packaging material is plastic bag, which is applied to the packaging of tomato sauce in the foreign food industry and food factory, and the packaging bag is sterilized with R-line APR and lon dreco aseptic packaging machines in England and Italy are aseptic packaging equipment for solid mixed food The packaging materials are metal cans The sterilization steam of metal cans is 221 ℃ ~ 226 ℃ The soup (liquid food) containing meat (solid food) and vegetables are sterilized and mixed respectively, and then aseptically filled into the sterilization cans Australia's stiriglen aseptic filling and packaging machine is a combination of solid food sterilizer and aseptic filling and packaging It is controlled by computer for continuous sterilization, which includes aseptic filling and packaging of solid food sterilization, cooling device and aseptic bag The packaging materials are respectively plastic bags and metal cans, fruit slices and meat products There are bacillus, Clostridium, Lactobacillus and Enterobacter desulfuricus in raw milk of dairy products Bacillus licheniformis and Bacillus cereus account for 80% of Bacillus UHT can kill bacillus Milk produced in Germany, France and other countries is sterilized at 140 ℃ ~ 145 ℃ for 2 ~ 6 seconds and then packed aseptically It is preserved at room temperature (20 ℃ ~ 27 ℃) for one month without deterioration The packaging materials shall be aseptic (sterilized) first and then packed aseptically Dairy products include milk for milk, coffee and juice The packaging process of milk includes sterilization, molding, sterilization, filling, sealing and trimming of plastic sheets In fruit juice drinks and fruit juice products, the growing microorganisms are acetic acid bacteria such as Acetobacter, Lactobacillus of plants, Leuconostoc, bacillus, Brevibacterium and Penicillium, Aspergillus, etc The aseptic packing method of fruit juice beverage is the same as that of milk The pH value of fruit juice is below 4.0, and the sterilization objects are yeast, mould, Lactobacillus, etc Sterilization Zui high temperature below 100 ℃, such as orange juice sterilization, 93 ℃ ~ 100 ℃ for 5 ~ 20 seconds rapid cooling to about 20 ℃, aseptic filling packaging, into the sterilized aluminum foil aseptic filling packaging shelf life can be maintained at room temperature for more than one year Sake sake is an acid food containing 10% - 20% alcohol and pH 4.5 Bacteria are not easy to grow, but Lactobacillus saprophyticus, Lactobacillus fermentans and Lactobacillus acidophilus can also grow and develop in sake containing 20% alcohol The aseptic packaging of sake is first heated to 70 ℃ by heat exchanger, and then filled and packed in aseptic room after cooling The packaging materials are plastic containers such as glass bottles, aluminum cans, pet, etc Zui near paper containers aseptic filling packaging is fashionable Soft cream is prone to obesity or cardiovascular disease due to excess fat For this reason, soft cream is fashionable in the world, which is half of margarine or fat cream, adding water and protein In order to prevent microbial propagation, Swedish soft cream is packed in sterile chamber with sterile cup In the meat processing products, the bacteria growing on ham and sliced sausage are mostly Bacillus bacteria Zui, followed by Staphylococcus, Lactobacillus, Micrococcus and other bacteria For the manufacture of meat processing products such as ham, the key is to sterilize the raw materials to make them sterile, and then smoke and slice them to kill the microorganisms.
