Microwave vacuum drying equipment to extend the shelf life of food, preserving food's original flavor and nutrients, to retain the physiological activity of the raw materials, enhance the functionality of health food, and increase the added value ofagricultural products, the obvious advantages of microwave vacuum dryingtechnologyone can effectively maintain the shape of the materials, color, nutrientsand aroma intact these features, the production is particularly important for health care products; can significantly save energy. In the freeze drying process, thematerials need to supplement the heat of sublimation. Under vacuum conditions, thelow temperature of vaporization of water to achieve a low-temperature drying intactto maintain the original color of the processed material, smell, taste and nutritional content to avoid the oxidative deterioration of the material of the active ingredient inrehydration products; microwave penetrate to the internal materials, materials for therotary motion of rotary system drive, so that the material is heated more evenly and dry more quickly, and its running costs are far lower than the freeze-drying andinfrared drying, energy saving, environmental health; full use of microwave heatinguniformity materials inside and outside temperature is small, both the use of vacuum drying characteristics, but also to solve the problem of vacuum heat conductiondifficulties, greatly improving the drying efficiency and product quality. Domestic and international information, the use of microwave equipment, heating the material, itsspeed and performance is 20 times of conventional heating methods. The equipment is mainly used in high value-added, and heat-sensitive agricultural and sideline products, health products, food, herbs, fruits and vegetables, chemical raw materials such as dehydration and drying; low temperature concentration forchemical products, removal of water of crystallization, the enzyme preparation dryvacuum extraction of Chinese herbal medicine is suitable for laboratory research institutions.
