Through the refrigeration system of the vegetable freeze-drying machine, the water-containing vegetables are frozen into a solid state at a low temperature, and then the vacuum pump system of the freeze-drying machine forms a vacuum environment, and the solid ice is dried directly into a gas 90% of the displacement water, and then enter the analytical drying need to remove the remaining 10% or so of the bound water, because the molecular force of the bound water is relatively strong, so the vegetable freeze-drying opportunity to provide more heat sublimation to remove the bound water, and obtain the vegetable freeze-dried food with water content in 2-5%. The working principle of the vegetable freeze-drying machine is to remove water through the principle of sublimation in three working stages to obtain freeze-dried vegetables with very little water.

The freeze-drying step is to transfer the vegetables into the drying bin of the freeze-drying machine equipment for vacuum freeze-drying. The freeze-drying process includes pre-freezing, sublimation drying and desorption drying of vegetables.

After drying, the vegetables are picked, packaged, sealed and stored in the warehouse. Pay attention to moisture.

Using vacuum freeze-drying technology to remove more than 95% of the water in vegetables, keep the original nutrients unchanged, and light weight, just moisture-proof packaging can be stored for a long time, not subject to seasonal and regional restrictions, anytime and anywhere can be eaten and carried.
