Sommige sterkpunte van vriesdroogmasjien

Drying methods are sun drying, boiling, oven drying, spray drying, and vacuum drying, but ordinary drying methods are usually carried out at temperatures above 0℃. The products dried will shrink the size and harden the texture. Most of the volatile components are lost, some heat-sensitive substances are denatured and deactivated, and some substances are even oxidized. Therefore, the dried product has a large difference in properties compared with that before drying.

The Freeze Dry Machine is basically carried out below 0℃, that is, in the state where the product is frozen, and only when the residual moisture content of the product is lowered in the later stage is the temperature above 0℃, but generally, it does not exceed 40℃. Under vacuum conditions, when the water vapor is directly sublimated, the drug remains in the frozen ice shelf, forming a sponge-like porous structure, so the volume after drying is almost constant. Before using it again, as soon as you add water for injection, it will dissolve immediately. Freeze Dry Machine has some advantages over other machines.

Eerstens sal baie hitte-sensitiewe stowwe nie gedenatureer of geïnaktiveer word nie.

Tweedens, wanneer dit by lae temperature gedroog word, gaan van die vlugtige komponente in die materiaal verlore.

Derdens, tydens die vriesdroogproses kan die groei van mikroörganismes en die werking van ensieme nie werk nie, sodat die oorspronklike eienskappe behou kan word.

Vierdens, aangesien dit in 'n bevrore toestand gedroog word, is die volume byna konstant, met die oorspronklike struktuur, en kom konsentrasie nie voor nie.

Ten slotte, aangesien die vog in die materiaal in die vorm van yskristalle bestaan ​​na voorvriesing, word die anorganiese soutoplosbare stowwe wat oorspronklik in water opgelos is eweredig in die materiaal versprei. Tydens die proses van sublimasie word die stowwe wat in water opgelos is, gepresipiteer, wat die verskynsel vermy dat die anorganiese sout wat deur die interne vogmigrasie na die oppervlak in die algemene droogmetode gedra word, op die oppervlak neerslaan om oppervlakverharding te veroorsaak.
