Equipment principle: In vacuum state, using the principle of ice crystallization, the moisture in the frozen material is directly sublimated into a gaseous state, so that the material is dried. Freeze-dried food is quick-frozen and vacuum ice-like dehydrated, which preserves the original color, aroma, taste, nutrients and the original appearance of the material, and has good rehydration properties.
Equipment description:
The machine has a reasonable structure, easy maintenance, fully automatic control, easy operation, can customize the freeze-drying curve, display and record various parameters, and the working status is clear at a glance. The operator only needs to press the button to start the machine, and unload according to the indicator light.
This machine also has the following advantages:
1. The vertical door-opening structure can realize the original position freeze-drying of materials.
2. The PLC+touch screen design can record the data during the freeze-drying process in real time.
3. The whole working process is fully automated, including refrigeration system, vacuum system, cooling system, electric control system, etc.
