The food freeze-drying machine is widely used in the freeze-drying of flowers, which is a drying method that preserves the original active ingredients and color, aroma, and shape basically unchanged. Including various processing treatments such as freeze-drying of fresh flowers, freeze-drying of immortal flowers, freeze-drying of flower extracts, and freeze-drying of flower pigments. TF food vacuum freeze-drying machine manufacturing factory can provide rose freeze-drying solutions, flower freeze-drying production line solutions, flower freeze-drying complete equipment turnkey engineering and other services according to users.

The design requirements for the automatic control system of the vacuum freeze-drying machine are simple to operate. Starting from the button of material insertion, the quick freezing vacuum sublimation drying is completed in one go, and it prompts to shut down and discharge the material after the freeze-drying is completed. The temperature and pressure control points should be carefully selected and reasonably controlled, and the correlation between quick freezing, vacuum holding, and heating should be appropriately controlled, with processes set for different materials.

The selection of food freeze-drying machines is determined based on the amount of raw materials processed. Normal food freeze-drying machines use the quality of aqueous solution as a reference for material tray loading, with a thickness of 1cm and a unit of 1 square meter as 10KG. Therefore, food freeze-drying machines are selected based on the freeze-drying area and the required processing capacity. A normal 50 square meter food freeze-drying machine can hold a raw material quantity of 500KG. The time for each batch is determined based on the freeze-drying process time of the freeze-dried food, and most freeze-drying times are around 24 hours per batch. Therefore, when selecting food freeze-drying equipment, consider the processing capacity and processing time, such as an annual processing capacity of 1000 tons of apples, which requires two 200 square meter food freeze-drying machines.

The food freeze-drying machine is normally used for food freeze-drying, additive freeze-drying, instant powder freeze-drying, traditional Chinese medicine freeze-drying, chemical raw material freeze-drying, and other processing purposes. The pharmaceutical freeze-drying machine is normally used for processing and drying drugs, cosmetics, biological products, raw materials, biological tissues, blood, probiotics, and bacterial strains. The technical requirements, configuration requirements, material requirements, sterility requirements, and functional requirements of food freeze-drying machines are different from those of pharmaceutical freeze-drying machines.

The working principle of a small food freeze-drying machine is to use the sublimation principle to freeze and crystallize water containing food at low temperature into a solid state. Then, in a vacuum environment, the solid ice is directly sublimated into a gas state without liquefaction to remove it, resulting in little water content and nutrients being retained. The color, shape, and taste remain unchanged, and it has the advantages of rehydration. It can be stored at room temperature for convenient storage and transportation.
