Vacuum Freeze-Drying Equipments
Almost all farm products have seasonable, local, hard store and transport problems, but those disadvantages may well solve by freeze-drying process. Those products may add water to recover their shape and flavour when they will be use. The vacuum freeze-drying is the best ideal drying process. Vacuum freeze-drying is a developed method, by which the product of containing water is quick frozen at lowtemperature state and the chamber is evacuated became a vacuum, then the ice sublimes and directly turns vapor to condense and discharge by refrigerating unit until water content reduce 95~98%, but product will still on the plate tray. Therefore the product maintained constant volume and turned into lacunose and floppy after drying, and will kept fresh and nutrition preferably to improve its additional value. Our vacuum freezing-drying units adopt imported low-temperature compressors to run circulating refrigeration system and cooperate with imported vacuum pumps and circular cool/hot mediums in drying process. Our units are easy operating and their products will keep uniform quality and easy reconvert.
