8. The user’s level and password can be set for decentralized operation management.
9. Can be customized according to user needs.
Compared with the usual drying methods such as sun drying, oven drying, spray drying etc., the freeze drying has the following advantages:
1. Proteins don't denature，Microorganisms maintain their biological activity.
2. Almost no loss of volatile substances, heat-denatured nutrients and aroma components in the product.
3. The growth of microorganisms and the action of enzymes can hardly be carried out and the product can best maintain its original properties.
4. After freeze-drying, the volume and shape of the product are almost unchanged, and the rehydration is good.
5. Freeze-dried under vacuum with very little oxygen, so that easily oxidized material is protected.
6. Freeze drying can remove95-99.5% of the moisture in the material, and the storage period of the product is longer.

Analysis of freeze-drying process for freeze drying equipment for sale
The freeze-drying bath of the freeze dryer involves processes such as freezing, heating, and gasification, which includes various processes such as heat transfer and mass transfer. From the perspective of heat transfer, freezing and heating are mutually reversible processes, and increasing the driving force (temperature difference) or reducing the thermal resistance is beneficial to the heat transfer process of the freeze dryer. In industrial production, reducing thermal resistance is often used to strengthen the heat transfer process. The resistance of heat transfer mainly comes from the inside and outside of the material. For example, reducing the thickness of the material layer and increasing the thermal conductivity can improve the freeze-drying rate of the freeze dryer. From the perspective of mass transfer, the moisture is sublimated from the solid phase to the gas phase and then separated. The removal process includes: the diffusion process of the gas phase from the inside of the material to the surface, the process of the gas phase migration from the material surface to the surface of the condenser, solidification and removal process, increasing the mass transfer driving force and reducing the mass transfer resistance can improve the freeze-drying rate of the freeze dryer.
Freeze dryers play a pivotal role in our country's metal heat treatment and heating work, which has also spawned the development of freeze drying equipment for sale.
