Foreign microwave energy food processing
    Microwave energy in food processing applications summed up in three main areas: dry exercise dehydration, baking and puffing ; bactericidal , insecticidal and enzyme inactivation, and thawed back to temperature . It is the success of recent years, foreign food processing applications of a new technology .
    Small household microwave cooking power , since 1947 the U.S. Raytheon made ​​the first commercial microwave and microwave Patent Publication 1950 ( Patent No. No: 2495429) , due to its ease of use , safety and fast Jie Jia workers , etc. have been quick into the kitchen , according to a company in Chicago statistics , the world's total sales in 1989 up to 25 million units. U.S. households own string of 75-80% ( 1989 ) , 54% in Japan , becoming the home cooking , baking cooking food hygiene effective .
Similarly, the application of industrial microwave heating equipment also gradually develop the industry in depth , according to the survey , the application of microwave energy in the United States industrial processing industry up to 17 different kinds, involving food , rubber, textiles, paper, making tobacco , drugs, wood, leather , ceramics , coal, plastics, casting, building materials , abrasives, cosmetics, and chemical arts images . In Japan, industrial microwave applications , the proportion of 70% concentrated in food sterilization , baking, thaw and mats ( tatami ) insecticide , etc. , until the end of 1978 statistics, the total power microwave device string up to 4 MW.
Foreign microwave energy in food processing applications are summarized as follows :
   ( A ) in respect of microwave drying and baking . Fermented and fried donuts , macaroni , noodles, cakes , seaweed microwave drying and baking has entered the industrial production, and cake. Mu Li heating walnuts or peel , peeled peanuts also to the laboratory stage
   ( 2 ) microwave microwave vacuum drying or freeze-drying in this regard . Soybeans, corn , rice , peanuts , thermal food has been successful in the laboratory . The juice , meat, fish -food , etc., have even further, you can use the microwave vacuum drying or microwave freeze drying .
   ( 3 ) microwave cooking broiled white side " chicken , bacon slices, fried potato chips, meat pies , rice , etc. has a mature microwave cooking broiled white industrial production technology, production of products have been recognized by consumers . The meat , oil refining, Levin vegetables boiled white are still experimental .
   ( 4 ) Microwave sterilization or preservation aspects . Sliced ​​bread , pies , tofu , milk, beverage microwave sterilization and preservation will be a great application , has become the industry mainstream, and prefabricated convenience food sterilization and preservation of the microwave will soon be applied to actual production .
   ( 5 ) microwave thawing heat or melt. Frozen meat , steak , fruit, chocolate , sleeves fat, egg yolk cream products, heating and melting microwave thawing also laboratory experiments .
