Sublimation is when a solid (ice) changes directly to a vapor without first going through a liquid (water) phase. Thoroughly understanding the concept of sublimation is a key building block to gaining knowledge of Standard-Type-Experimental-Vacuum-Freeze-Dryer. Sublimation is a phase change and heat energy must be added to the frozen product for it to occur. Sublimation in the freeze drying proce

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 wate

ice crystals after pre-freezing, the dissolved inorganic salts dissolved in water are uniformly distributed in the material; 9. The material dried by the Production Freeze Dryeris porous and porous. It dissolves quickly and completely after adding water, and it almost immediately restores its original properties. 10. Since the drying is carried out under vacuum, oxygen is minimal, so

ice) in the object to directly sublimate into water vapor, remove from the items, and make the items dry. After the material is pre-treated, it is sent to a quick-freezing chamber for freezing, then sent to a drying warehouse for sublimation and dehydration, and then packaged in a post-processing workshop. The vacuum system establishes a low pressure condition for the sublimation drying chamber,
