Large Food Industrial Vacuum Freeze Dryer Machine
The food vacuum freeze dryer is a machine used for freeze-drying food. The process involves freezing the food first, then subjecting it to a low-pressure environment to allow sublimation (the transition of a solid directly to a gas, skipping the liquid phase) to occur. This removes water from the food while preserving its physical structure and nutritional content. The resulting product is lightweight, easy to store, and has a long shelf life. The food vacuum freeze dryer is widely used in food processing, pharmaceuticals, and other industries.
Features
Features：
The material used in the partition is made of aerospace-grade aluminum alloy and has double-sided radiation heating. It has a radiation rate of over 90% and provides good temperature uniformity. The mixed refrigerant medium used has a low freezing point and high boiling point, which ensures high heat transfer efficiency and a long service life. The drying curve optimization control algorithm of the product helps to control the heating rate and vacuum degree values during the drying stage. Additionally, the patented gas diversion design and control technology provide a strong water capture ability.
