The dryer features heat transfer coefficient

The vacuum dryer features heat transfer coefficient, high thermal efficiency, the item oxidized small, large capacity. Apply to dry all forms of granular, small block, sheet materials and humidity. In the feed market, the aircraft can be used for drying chicken cow manure, grass, slag worse. freeze dryer machine vacuum freeze-drying is the use of refrigeration equipment will be the very first to freeze into a solid material, pulls out into a vacuum to ensure that the direct sublimation of solid ice to gaseous water vapor, in order to achieve the intention of drying. Fluid bed dryer has many positive aspects: low pressure material not readily 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 very same as before. Freeze-drying a wide range of applications, but its price is somewhat high, so the choice must consider when freeze-drying economic interests can not be used thoughtlessly. At this moment, the vacuum freeze-drying technology is mainly used in food, medicine and feed additives. Far far more Info Click on : air stream dryer
