Vegetable freeze dryer

Vegetable freeze dryerAlso known as vegetable vacuum freeze dryer. utilizeVegetable freeze dryerThe working principle is that vegetables are processed into freeze-dried products through vacuum freeze-drying, which preserves the original color, body shape, and nutritional components of vegetables, has good rehydration properties, and can be stored for a long time at room temperature. Introduce FZG hereVegetable freeze dryerThe working principle and structural composition.

Vegetable freeze dryerThe working principle of water is based on the sublimation principle, which refers to the characteristic of the three-phase states of water, namely liquid, solid, and gas, converting and coexisting with each other at different temperatures and vacuum statesVegetable freeze dryerThe refrigeration system freezes water containing vegetables into a solid state at low temperatures, and then uses the vacuum pump system of the freeze-drying machine to create a vacuum environment in the drying chamber. Under high vacuum conditions, the solid ice is directly sublimated into gas to remove 90% of the flowing water, and then enters the analytical drying process to remove the remaining 10% of bound water. Because the molecular strength of bound water is relatively strongVegetable freeze dryerIt will provide more heat to sublime and remove bound water, resulting in vegetable freeze-dried food with a moisture content of 2-5%.Vegetable freeze dryerThe working principle of freeze-dried vegetables is to use the principle of sublimation to remove water in three stages, resulting in freeze-dried vegetables with very little water content.

Vegetable freeze dryerIt consists of a freeze-drying box and a unit frame, mainly composed of accessories such as a compressor, vacuum pump, circulation pump, and PLC electronic control module, forming a refrigeration system, vacuum system, circulation system, electronic control system, etc. The operation of each system is controlled by PLC electronic control. Currently FZGVegetable freeze dryerIt has been widely used in freeze-drying and processing vegetables such as lettuce, tomatoes, broccoli, chili peppers, scallions, cilantro, scallions, cauliflower, onions, beans, spinach, edible mushrooms, yams, carrots, etc., providing opportunities for the development of deep processing of vegetables!
