The dryer features heat transfer coefficient, high thermal efficiency, the product oxidized small, large capacity. Apply to dry all kinds of granular, small block, sheet materials and humidity. In the feed industry, the aircraft can be used for drying chicken cow manure, grass, slag worse.
vacuum freeze-drying vacuum freeze-drying is the use of refrigeration equipment will be the first to freeze into a solid material, pulls out into a vacuum so that the direct sublimation of solid ice to gaseous water vapor, so as to achieve the purpose of drying. Fluid bed dryer has many advantages: low pressure material not easily oxidized, inhibited the activity of some cells; low temperature heat-sensitive materials in components retained to maximize retention of materials in the original composition; formed when the skeleton of pre-freeze , dried material can maintain the original shape, the formation of microporous structure; rehydration, and can recover quickly absorbing water, its quality and drying the same as before. Freeze-drying a wide range of applications, but its cost is relatively high, so the choice must consider when freeze-drying economic interests can not be used blindly. At present, the vacuum freeze-drying technology is mainly used in food, medicine and feed additives.
