  Have you figured out the technical advantages of the pilot freeze dryer?
  Drying is a very old operation, but the heating and drying of powders and biological products often cause irreversible agglomeration of particles, especially in the preparation of ultra-fine powders. Nanoparticles in the liquid phase will agglomerate into difficult-to-disperse agglomerates when dried. This is mainly because water is emitted from the inter-particle pores during the ordinary particle drying process, and the surface tension results in extremely high additional pressure, which compacts the particles together into agglomerates.
  Vacuum freeze-drying can avoid this problem. Freeze-drying is to freeze the gel or blood to be dried to a solid first, and then remove the water by vaporizing the water in it through sublimation under reasonable conditions. The chemical process does not affect the agglomeration state of solid particles, so the original particles can be kept intact without being compacted and agglomerated.In addition, freeze-drying is very suitable for processing biological products, such as blood, because it does not have high temperature operation, which can prevent biological Deteriorated products.
  Pilot Freeze Dryer technology has a wide range of applications in the fields of biological engineering, pharmaceutical industry, food industry, materials science and deep processing of agricultural and sideline products. So what are the advantages of freeze drying technology? Xiaobian will introduce them one by one here.
  66 advantages of freeze dryer technology:
  1. Because drying is performed under vacuum, there is very little oxygen, so some easily oxidizable substances are protected.
  2. In the process of freeze dryer, the growth of microorganisms and the role of enzymes cannot be performed, so it can maintain the original sexual performance. Because it is dried in a frozen state, the volume is almost unchanged, the original structure is maintained, and no concentration occurs.
  3, freeze-dryer is carried out at low temperature, so it is especially suitable for many heat-sensitive substances. Such as proteins, microorganisms, etc. will not denature or lose biological vitality. Therefore, it is widely used in medicine.
  4. Drying can eliminate more than 95-99% of water, so that the dried product can be stored for a long time without deterioration.
  5. When drying at low temperature, the loss of some volatile components in the substance is very small, which is suitable for drying some chemical products, medicines and food.
  6. After drying, the material is loose and porous, and it is sponge-like. After adding water, it dissolves quickly and completely, and the original properties are restored almost immediately.
