Superiority

The bench-top type Freeze Dryer consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components are drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling devices, etc. It works by freezing the dried item to below the triple point temperature and then sublimating the solid water (ice) in the item to water vapor under vacuum conditions, removing it from the item and drying the item. After the material is pretreated, it is sent to the quick freezing warehouse for freezing, and then sent to the drying chamber for sublimation dehydration, and then packaged in the post-treatment workshop. The vacuum system establishes a low pressure condition for the sublimation drying chamber, the heating system provides sublimation latent heat to the material, and the refrigeration system provides the required cooling capacity to the cold trap and the drying chamber. The equipment adopts high-efficiency radiant heating, the material is heated evenly; the high-efficiency water trap is used, and the defrosting can be realized quickly; the high-efficiency vacuum unit can be used to realize the separation of oil and water; the parallel centralized refrigeration system is adopted, and the multi-channel cooling is required on demand. Stable, energy-saving; artificial intelligence control, high control accuracy, easy to operate.
　　The quality requirements for freeze-dried products are: constant biological activity, uniform appearance and color, full shape, firm structure, fast dissolution rate and low residual moisture. To obtain high quality products, a comprehensive understanding of the theory and process of lyophilization should be obtained. The lyophilization process consists of three stages of pre-freezing, sublimation and re-freezing. Reasonable and effective shortening of the freeze-drying cycle has obvious economic value in industrial production.

Details

lab equipment vacuum freeze dryer technology has a wide range of applications in the fields of bioengineering, pharmaceutical industry, food industry, materials science and deep processing of agricultural and sideline products. So what are the advantages of freeze-drying technology Xiaobian is here to introduce you one by one.
1. In the process of lab equipment vacuum freeze dryer, the growth of microorganisms and the action of enzymes cannot be carried out, so the original sex can be maintained. Since the drying is carried out in a frozen state, the volume is almost constant, the original structure is maintained, and concentration does not occur.
2. Since the drying is carried out under vacuum, there is very little oxygen, so some easily oxidizable substances are protected.
3. Drying can exclude more than 95-99% of water, so that the dried product can be preserved for a long time without deterioration.
4. The dried material is porous and spongy. After adding water, it dissolves quickly and completely, and immediately restores the original trait.
5. lab equipment vacuum freeze dryers are carried out at low temperatures and are therefore particularly suitable for many heat sensitive materials. Such as protein, microorganisms and the like will not degenerate or lose biological vitality. Therefore, it is widely used in medicine.
6. When drying at low temperature, some volatile components in the material are lost little, suitable for some chemical products, medicines and foods to be dry.
