The whole apparatus is mainly divided into two parts, i.e. the freeze-drying chamber 2 and the rear-end equipment (including the condenser 18 and the vacuum pump), which is also substantially integrated in one chamber, and the chamber door 14 is also mounted at the rear end of the chamber.
The outside of freeze-drying case 2 articulates there is door 1, be equipped with the fastener on the door 1, as shown in figure 1, the one end and the freeze-drying case 2 body of fastener are articulated, and the other end is bolt spare, and when door 1 closed, rotatory to the door 1 outside with the fastener to through rotatory mode, make bolt spare compress tightly door 1 and carry out spacing fixed.
The freeze-drying incasement 2 is seted up the cavity, add in the cavity and be equipped with the plywood, the tamponade hydro-cylinder 3 is installed at the top of plywood, and the plywood is used for placing dry raw materials, and the plywood passes through the support, the guide arm is fixed in freeze-drying incasement 2, as shown in figure 1, the guide arm is installed in the both sides of support for fixed and spacing, moves about being driven by tamponade hydro-cylinder 3, is convenient for advance/ejection of compact and washing.
The condenser 18 is connected at the rear end of the freeze-drying box 2, and a butterfly valve 13 is connected between the condenser 18 and the freeze-drying box 2.
The condenser is a vacuum-tight container. Inside it, there is a metal adsorption surface with large surface area, the temperature of the adsorption surface can be reduced to-75 deg.C or lower, and the low temperature can be constantly maintained. The condenser is used for freezing and adsorbing water vapor sublimated from the product in the freeze-drying box on the metal surface of the product.
The cooling of the condenser is obtained by direct expansion of the refrigerant, each group of condenser coils is provided with an independent compressor refrigerating system, and a temperature probe is used for testing one group of coils respectively
The vacuum pump 8 is communicated with the freeze-drying box 2, one side of the condenser 18 is connected with the compressor 7 and the water condenser 12, the other side of the condenser 18 is connected with the balance cylinder 4, the balance cylinder 4 is connected with the circulating pump 11, a cooling water inlet and a cooling water outlet are formed in the circulating pump 11, one side of the condenser 18 is fixedly provided with the electric cabinet 6, the electric cabinet 6 is embedded with the plug-in nozzle 15, the plug-in nozzle 15 is connected with the compressor 7, the balance cylinder 4 is connected with the plate type heat exchanger 5, and one side of the plate type heat exchanger 5 is connected with the electric heater 10.

Fig. 3 is a schematic diagram of a circulation system, and freeze-drying is essentially a process technique that relies on temperature differences to cause mass transfer. The product is first frozen on the laminate and after the freeze drying process has begun, water vapor sublimes from the frozen product and re-condenses as ice on the catch surface of the condenser 18. To obtain stable sublimation and condensation, heat is supplied to the product from the laminate and removed from the capturing surface of the condenser, which capturing surface must be maintained at a lower temperature than the product.
The refrigeration and heating of the plate layer are all carried out through the heat transfer of the heat transfer oil, the circulating pump 11 is installed to enable the heat transfer oil to continuously circulate in the whole system, it is worth mentioning that the circulating pump 11 is loaded with two motors, one is a working motor, and the other is a standby motor. The system has good backup function and wide applicability. At the outlet of the circulating pump 11, a pressure gauge and a pressure relay are installed to reflect the outlet pressure, and an over-temperature alarm relay is additionally arranged on the electric heater 10.
The action of a pressure relay of the circulating pump is as follows: when the pump starts, the embedded PLC system automatically collects the outlet pressure of the pump, if no pressure exists, the motor or the relay is indicated to have problems, and at the moment, the other standby motor is automatically opened in the program, so that the normal operation of the system is ensured.
And in the sublimation stage, when the function of heating control in the control system fails, the temperature of the heat-conducting oil reaches a set value, the electric heating cannot be automatically cut off, the heating is continued, and the temperature is continuously increased. When the temperature reaches the upper limit of the set value of the over-temperature alarm relay (generally set to 70 ℃), the relay can forcibly cut off the power supply for heating. Otherwise, the heat insulating material of the electric heating pipe will burn due to overheating. The overtemperature alarm relay plays a role in double protection
The working principle of the utility model is that firstly, the raw material is manually put into the laminate of the freeze-drying box 2, and the product completes the operations of drying, desorbing moisture content and full-pressure plugging and the like under the sterile state in the freeze-drying box 2
Firstly, a compressor 7 and auxiliary facilities thereof are used for providing cold sources for the freeze-drying box 2 and the condenser 18, and a single-unit double-stage compressor is adopted, so that the refrigeration process is advanced, and the long-time action is ensured without faults. Each set of compressor is provided with an independent refrigeration cycle system, the plate layer and the condenser are respectively served through the plate type heat exchanger 5, and the compressor 7 can independently refrigerate the plate layer or the refrigeration condenser.
After the moisture of the materials in the laminate is frozen, the vacuum pump is started at the same time, the vacuum pump group is adopted to form strong suction capacity, vacuum is formed in the drying chamber and the condenser, on one hand, the moisture in the freeze-drying box 2 is promoted to be evaporated (sublimated) in a vacuum state, on the other hand, a vacuum degree gradient (pressure difference) is formed between the condenser 18 and the freeze-drying box 2 by the vacuum system, and the moisture in the freeze-drying box 2 is sublimated and then is captured by the condenser 18. The condenser 18 is typically provided with coils on which the trapped moisture eventually condenses. Until the materials are completely dried, the ice on the coil pipe is heated and defrosted, and finally formed liquid water enters the water ring pump 9 and is discharged out of the equipment.
