Connection, temperature between the two directly exchange, and keep the two very big by respective influence at work；And above cold trap walls
It is connected with vacuum pump by pipeline, so that the air-flow come out from cryodesiccation chamber is put into pipeline only by the upper part of cold-trap, causes cold
The ability that trap captures moisture reduces；On-condensible gas after supplementary set is directly entered vacuum pump, a small amount of liquid carried in on-condensible gas
Vacuum pump can be damaged, influence its service life.Vacuum pump in selection, is selected according to maximum demand
, but material is in vacuum freeze drying, different and in drying process each stage with material kind, to indoor pressure is lyophilized
It is required that it is different, it is adjusted so to be evacuated partial pressure to vacuum pump.Disease can be inevitably infected with when material after quick-frozen enters cryodesiccation chamber
Bacterium pollutes；After material moisture distillation after drying, institutional framework becomes cavernous body, and taking-up of directly uncapping is oxidized easily and becomes
It is color distortion.
