Leaf-eating grass aliases: protein grass, amino acid grass, etc. it is a high-protein, high-nutrition, high-yield, high-efficiency "vegetative plant", rich in protein, amino acids, chlorophyll, vitamins and various minerals and other nutrients.

With the development of vacuum freeze-drying technology in agriculture, the leaf-eating grass is dried and processed in a low-temperature vacuum freeze dryer. The leaf-eating grass can not only preserve the original various active substances and nutrients, but also store at room temperature for 1~3. At the same time, it is convenient for storage and transportation, which greatly enhances the value advantage of leaf-eating grass.

Freeze dryer is a device for stabilizing and drying substances. The working principle of freeze-drying leaf-eating grass is to freeze and crystallize water-containing leaf-eating grass at low temperature through sublimation, and then directly sublimate the solid ice into gas to remove it under high vacuum state, so as to ge freeze-dried leaf-eating grass with very little water content, freeze-drying Leaf-eating grass has the advantage of good rehydration. The leaf-eating grass has been in a low temperature and vacuum environment during the freeze-drying process. At low temperature, the heat-sensitive substances and volatile substances in the leaf-eating grass are protected, and the growth of enzymes is restrained. At the same time, the oxidation reaction basically stagnates in a vacuum state. Sublimation drying is a physical phenomenon in which water molecules migrate from the outside to the inside, leaving a porous sponge, so the nutrients and active substances are preserved, and it has very good rehydration properties.

The freeze dryer has the advantages of preserving nutrients and color, aroma, taste, and shape in the freeze-dried processing of leaf-eating grass. The freeze dryer can be used to process freeze-dried powder of leaf-eating grass, freeze-dried spinach powder, and freeze-dried parsley powder, vegetable freeze-dried powder, etc.
