Microwave drying sterilization extraction advantages
1. Microwave drying and sterilization to maintain the dual bactericidal effect of rapid heating and non-thermal effects of microwaves with thermal effects. Compared with conventional thermal drying and sterilization, the required drying and sterilizing effects can be obtained at relatively low temperature and in a short time. . The general sterilization temperature is 65-70. C, 75-80. C or 103-121. In C, the time is 3-8 minutes, and it can retain more food nutrients and color, fragrance, taste, shape and other flavors. For example, the vitamin C retained by conventional heat treatment of vegetables is 46-50%. In contrast, microwave treatment can achieve 60-90% of vitamin C retention, and conventional heating method has a vitamin A retention value of 58%. Microwave heating can reach 84%.
2. Microwave drying sterilization saves energy
3. Microwave drying and sterilization energy conversion efficiency is high, generally above 70%. The microwave directly treats the food, and the heating box itself is not heated, so there is no additional heat energy loss, so energy saving, generally saving 30-50%.
4. Microwave chemical extraction High-frequency drying uniform and thorough conventional thermal drying, sterilization is started from the surface of the material, and then transferred to the inside of the material through heat conduction. There is a temperature difference between the inside and outside of the material, and the internal and external drying and sterilization effects are poor. In order to maintain the flavor and shorten the processing time, the internal temperature is not sufficient to affect the drying and sterilization effects. This phenomenon can be improved by increasing the processing temperature, however, this causes the color, fragrance, taste, shape and the like of the surface of the article to be degraded. The microwave has the penetrating property, and the surface and the interior simultaneously act to ensure that the internal and external temperatures together achieve the required value, so the drying and sterilization are uniform and thorough.
