Abstract
The utility model relates to a vacuum freezing dryer, which is mainly composed of a freeze-drying box, a hollow plate layer, a main valve, a cold trap, a trapping pipe, a pump out valve, a vacuum pump, a cold trap valve, a refrigerating machine, a refrigerating valve, a freezing exchanger, a heater, a circulating pump, etc. The utility model is the vacuum freezing dryer which has the advantages of simple structure, convenient disinfection, no drug pollution and uniform temperature of materials.
Description
The utility model relates to a kind of vacuum freeze drier, the vacuum freeze drier that particularly a kind of suitable pharmacy, biological products are used.
Conventional vacuum freeze drier, shortcoming are to be unfavorable for sterilization, pollute medicine, are unfavorable for that material temperature is even.
The purpose of this utility model be to provide a kind of simple in structure, be beneficial to sterilization, can not pollute medicine, be beneficial to the uniform vacuum freeze drier of temperature of charge again.
For achieving the above object, the utility model is taked following design: this vacuum freeze drier, mainly by freeze drying box, cold-trap, vavuum pump, refrigerator, cool exchanger, parts such as circulating pump constitute, the hollow flaggy is housed in the described freeze drying box, be equipped with in the described cold-trap and catch pipe, connect with main valve between described freeze drying box and the cold-trap, described seizure pipe links to each other with described refrigerator by the cold-trap valve, device has refrigeration valve between described cool exchanger and the refrigerator, described hollow flaggy one end is connected with described circulating pump, the other end is connected with described cool exchanger, install having heaters between described circulating pump and cool exchanger, device has evacuation valve between described cold-trap and the described vavuum pump.
Because the utility model adopts above technical scheme, simple in structure, be beneficial to sterilization, can not pollute medicine, it is even to be beneficial to temperature of charge again.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model one embodiment schematic diagram
As shown in Figure 1, this vacuum freeze drier of the utility model, mainly by freeze drying box 1, cold-trap 4, vavuum pump 7, refrigerator 9, cool exchanger 11, circulating pump 13 parts such as grade constitute, it is characterized in that: in the described freeze drying box 1 hollow flaggy 2 is housed, be equipped with in the described cold-trap 4 and catch pipe 5, connect with main valve 3 between described freeze drying box 1 and the cold-trap 4, described seizure pipe 5 links to each other with described refrigerator 9 by cold-trap valve 8, device has refrigeration valve 10 between described cool exchanger 11 and the refrigerator 9, described hollow flaggy 2 one ends are connected with described circulating pump 13, the other end is connected with described cool exchanger 11, device having heaters 12 between described circulating pump 13 and cool exchanger 11, device has evacuation valve 6 between described cold-trap 4 and the described vavuum pump 7.
Can place material on the hollow flaggy 2 that is equipped with in the freeze drying box 1.Heater 12, cool exchanger 11, circulating pump 13 have been formed the circulatory system with hollow flaggy 2.The low-viscosity heat-conducting medium carries out indirect and refrigeration to flaggy in the circulatory system, material is heated equably with freezing.
Cold-trap 4 was equipped with in (claiming water condenser, water catcher, water vessel again) catches pipe 5, is used for catching the moisture content that the material distillation is come out.
The cool exchanger 11 of the circulatory system, the seizure pipe 5 in the cold-trap 4, refrigerator 9 etc. have been formed refrigeration system, are used for directly freezing to the material indirect refrigeration with to cold-trap.
Below only be an embodiment of the present utility model, any based on equivalents of the present utility model all within protection domain of the present utility model.
