Application of microwave equipment in food processing industry

Food processing includes many processes such as sorting, pulverizing, separating, mixing, sterilizing, refrigerating and drying raw materials, and the drying process is a key link to ensure food quality. Most foods are wet materials that contain a lot of water. If the food is too much water, it will cause microbial life activities, lead to food spoilage or shorten the shelf life of the food, and increase transportation costs. Drying the food can prevent the growth of microorganisms in the food, facilitate storage, and at the same time reduce the volume and weight of the food, thereby reducing transportation costs. Due to the variety and variety of foods, such as powder, tablets, strips, blocks, paste, etc., there are liquid, wet solid, biological tissue, etc., together with a series of physical and chemical changes in the drying process of food materials. (such as shrinkage, surface hardening, porosity, porosity, irreversibility of recovery), as well as changes in food nutrient content, flavor change, browning, etc., so the structure of the dryer, the working characteristics and performance parameters of the dryer There are different requirements.

Traditional drying methods have the disadvantages of uneven heating, long baking time and high labor intensity. In the late 1990s, researchers in China's food drying machinery conducted a lot of research work on electromagnetic radiation drying equipment, and developed microwave drying equipment. It solves a series of shortcomings such as long drying time, high temperature and serious damage to nutrients, making food drying a big step.

Since its establishment in 2003, Yantai Longteng Microwave Equipment Co., Ltd. has absorbed the advanced technology of foreign Zui and developed the LT series microwave food drying equipment, which has the advantages of fast drying speed, high thermal efficiency, uniform heating, no pollution and no damage to food. Features such as condiments, snack foods, tea honeysuckle, bottled food, bagged food, etc., can be widely used in food drying.
