የቀዘቀዘ ደረቅ ማሽን የስራ መርህ

የቀዘቀዘ ደረቅ ማሽን uses a drying technique by the principle of sublimation. It freezes the dried material at a low temperature and then directly sublimates the frozen water molecules into water vapor under a suitable vacuum environment. The process of escaping. The product obtained by lyophilization is called a lyophilizer, and the process is called lyophilization.

The Freeze Dry Machine is composed of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components of the lyophilizer are a drying oven, a condenser, a refrigeration unit, a vacuum pump, and a heating/cooling device. The lyophilizer works by freezing the dried object to below the triple point temperature and then sublimating the solid water (ice) in the article to water vapor under vacuum conditions, removing it from the products, and drying the products. After the material is pre-treated, it is sent to the quick-freezing bin for freezing, and then sent to the drying bin 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.
