ለምን GF ፍሪዝ ደረቅ ማሽን መምረጥ

There are various drying methods such as 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 method 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. GF የቀዘቀዘ ደረቅ ማሽን has some advantages over other machines.

በመጀመሪያ ደረጃ, ብዙ ሙቀት-ነክ የሆኑ ንጥረ ነገሮች አይወገዱም ወይም አይነቃቁም.

በሁለተኛ ደረጃ, በዝቅተኛ የሙቀት መጠን ሲደርቁ, በእቃው ውስጥ ያሉ አንዳንድ ተለዋዋጭ አካላት ጠፍተዋል.

በሶስተኛ ደረጃ, በበረዶ ማድረቅ ሂደት ውስጥ, ረቂቅ ተሕዋስያን እድገት እና የኢንዛይሞች ተግባር ሊሰራ አይችልም, ስለዚህም የመጀመሪያዎቹን ባህሪያት ጠብቆ ማቆየት ይቻላል.

አራተኛ, በረዶ በሆነ ሁኔታ ውስጥ ስለሚደርቅ, መጠኑ ቋሚ ነው, ከመጀመሪያው መዋቅር ጋር, እና ትኩረቱ አይከሰትም.

በመጨረሻም ፣ በእቃው ውስጥ ያለው እርጥበት ከቅድመ-ቀዝቃዛ በኋላ በበረዶ ክሪስታሎች መልክ ስለሚኖር በመጀመሪያ በውሃ ውስጥ የሚሟሟ ኦርጋኒክ ያልሆኑ ጨው-የሚሟሟ ንጥረ ነገሮች በእቃው ውስጥ በእኩል መጠን ይሰራጫሉ። በ sublimation ሂደት ውስጥ በውኃ ውስጥ የሚሟሟት ንጥረ ነገሮች ይንሰራፋሉ, ይህም በአጠቃላይ ማድረቂያ ዘዴ ውስጥ በውስጣዊው እርጥበት ፍልሰት የተሸከመው ኦርጋኒክ ያልሆነ ጨው በላዩ ላይ በመዝለቁ ምክንያት የሚከሰተውን ክስተት ያስወግዳል.
