Description
Technical field
The utility model relates in a kind of freeze dryer the system that the heat conduction medium (abbreviation heating agent) to its heating agent circulatory system heat, and it is suitable for containing the freeze dryer of the heating agent circulatory system, as to cryodesiccated freeze dryer of article etc.
Background technology
The characteristics of vacuum freeze-drying technique are to be frozen into solid-state article under vacuum environment, for removal moisture carries out lyophilization.These characteristics have determined: place the heat exchange shelf (abbreviation shelf) of article in the drying box of freeze dryer, must have the function of placement article on the shelf being carried out frozen cooling and heat temperature raising.The article that will contain large quantity of moisture are frozen into solid-state, need the heating agent circulatory system of freeze dryer to provide cold to shelf; Be frozen into solid-state article water sublimed drying with this, need the heating agent circulatory system of freeze dryer to provide heat to shelf.
At present, the freeze dryer that contains the heating agent circulatory system both at home and abroad, as be used for the freeze dryer that article are produced, the shelf of its heating agent circulatory system and refrigeration system is lowered the temperature the loop works principle generally as shown in Figure 1, and its heating agent circulatory system mainly contains shelf 1, reservoir 2, circulating pump 3, electric heater 4 and heat exchanger 5; Heat exchanger 5, refrigeration compressor 6, condenser 7 and choke valve 8 are mainly contained in the shelf cooling loop of its refrigeration system.C mouth among Fig. 1 and d mouth are respectively the supply opening and the return-air mouths in refrigeration system cold-trap cooling loop.Gaseous refrigerant in the refrigeration system, be condensed into liquid state through condenser 7 heat releases, through choke valve 8 throttling step-downs and heat absorption and flash to gaseous state heat exchanger 5 in, thereby be that the heating agent of the heating agent circulatory system is lowered the temperature, heating agent conducts cold to article by shelf 1 again; The electric heater 4 that is provided with on the heating agent circulatory system can directly heat the heating agent in the heating agent circulatory system.
Be used for the condenser of the refrigerating system of freeze dryer of article production, adopt water-cooled condenser usually.Under the effect of refrigeration compressor, cold-producing medium evaporates and condensation cycle in airtight refrigeration system continuously.Cold-producing medium is through throttling and evaporation, the heat around absorbing and gasifying; Through the overcompression heat release, in the water-cooled condenser of refrigeration system, emit self heat and condensation.The heat that condensation of refrigerant discharges passes to recirculated cooling water by water-cooled condenser, and recirculated cooling water passes through outdoor cooling tower to airborne release with the heat that absorbs.
The article freeze dryer is in the article freezing dry process, and the steam that cold-trap needs the continuous capturing distillation to produce is so refrigeration compressor operation continuously all the time finishes until dry run; The exhaust gas heat of refrigeration compressor passes through outdoor cooling tower all the time to airborne release, and this heat is not utilized.Because lyophilization need constantly absorb heat, so the article lyophilization finishes until drying from beginning, the needed heat that distils provides by electric heater.The result of this operation is: on the one hand, the exhaust gas heat of refrigeration compressor is all wasted; On the other hand, electric heater provides necessary heat consumes energy for distillation again; The excessive energy resource consumption of freeze dryer has caused the freeze-drying cost of article too high.
