Sekiga Tekniko de Frostigilo

Drying technique is used on the Frostigi Seka Maŝino uses 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 product obtained by lyophilization is called a lyophilizer, and the process is called lyophilization.

La substanco ĉiam estas en malalta temperaturo (frosta stato) antaŭ sekiĝo, kaj la glacikristaloj estas egale distribuitaj en la substanco, kaj la sublima procezo ne kaŭzas koncentriĝon pro malhidratiĝo por eviti kromefikojn kiel ŝaŭmadon kaj oksigenadon kaŭzitan de akva vaporo . La seka materialo estas pora en formo de seka spongo, kaj la volumo estas esence senŝanĝa, do ĝi estas facile solvebla en akvo kaj restarigita al sia originala stato. Fizika kaj biologia denaturigo de seka substanco estas malebligita laŭ la plej granda mezuro.

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.
