Vacuum dryer hnathawh dan tur .

Vacuum dryer hi a bik takin drying heat-sensitive, awlsam taka decomposable leh awlsam taka oxidized substance te atana siam a ni. A chhungah inert gas a khat thei bawk. Entirnan, complex component nei thil thenkhat pawh a vawt nghal vat thei bawk. Pressure hniam tak hnuaia a vawt lai hian oxygen awm zat a hniam hle a, chu chuan thil a vawt tur chu a oxidation leh a chhe tur a veng thei a ni. Chuvangin, thil hlauhawm tak tak kang thei leh puak thei thil engemaw zat a vawt thei bawk. Material chhunga tui awm chu temperature hniam takah a vaporize thei bawk a, chu chuan heat thenkhat vawt tir a awlsam zawk-sensitive materials te pawh a ti vawt thei bawk. Thil hlu leh tangkai tak takte pawh a dried materials-a a recover thei bawk. Hei hian thil chi hrang hranga thil tha lo leh hlauhawm tak tak thenkhat a chhuah loh nan a veng thei a, chu chuan boruak tichhe lo chi "green" drying a siam thei a ni.
