Galuega Fa'avae ole Masini Fa'amago Fa'a'aisa

Freeze Dry Machine adopt 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 product obtained by lyophilization is called a lyophilizer, and the process is called lyophilization.

O le vailaʻau e masani lava i le maualalo o le vevela (tulaga malulu) aʻo leʻi faʻamago, ma o tioata aisa e tufatufaina tutusa i totonu o le vailaʻau, ma o le sublimation process e le mafua ai le faʻaogaina ona o le faʻamaʻaina e aloese ai mai aʻafiaga e pei o le faʻafefe ma le faʻamaʻiina e mafua mai i le ausa vai. . O mea mamago e porous i foliga o se omomi mago, ma o le voluma e matua le suia, o lea e faigofie ai ona solu i le vai ma toe faʻafoʻi i lona tulaga muamua. O le fa'aleagaina o le tino ma le ola o mea mamago e matua puipuia lava.

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.
