1.
Dryer body: According to different production requirements, the dryer body can be made of A3 steel plate or A3 steel plate with 1Cr18Ni9Ti stainless steel plate or 1Cr18Ni9Ti stainless steel plate
.
The 1Cr18Ni9Ti stainless steel plate wall is easy to clean, which is beneficial to meet the sterile requirements of drugs, and has a good anti-corrosion effect on acid and alkali
.
There are three sight glasses on the front and back of the device, which is convenient for observing the drying of materials.
The sight glass liner is made of silicone rubber, which is not only sealed but also suitable for drug drying requirements
.
The body is provided with a vacuum gauge and a thermometer, as well as a disinfection port, which is used for disinfection and protection of materials before drying or in the middle and later stages of drying
.
The disinfection gas and protective gas are selected by the user.
During the disinfection process, the vacuum pump and the vacuum valve must be closed.
After the disinfection is completed and the disinfection port is closed, the vacuum pump can be turned on and the vacuum valve can be opened for vacuuming
.
If sterile operation is required, a steam filter (for the sterilization port) and an air filter (for the vent valve port) should be provided
.
Considering that the input steam pressure of the disinfection port is too high, a safety valve is also installed on the body to protect <≤0.
2 MPa>
.
There is a steam inlet (or hot water outlet) on the body, a steam trap interface (or hot water inlet) and a sewage outlet under the body.
Considering that the user is drying materials with high water content, it will be in the device during the drying process.
A large amount of water accumulates in the body, which forms secondary evaporation and slows down the drying speed.
The factory also produces a sewage water storage tank accessory, which can overcome the above drawbacks.
After the drying is completed, the materials are taken out, and the sewage can be discharged
.
2.
Drying rack in the dryer: According to different drying requirements, the drying rack can be made of 20# seamless steel pipe or 1Cr18Ni9Ti seamless steel pipe
.
According to the different drying temperature requirements of materials, the drying rack has three types: steam type, hot water type and electric heating type
.
3.
Hot water tank: The hot water tank is specially designed and produced for the hot water type vacuum dryer
.
There are water level gauge, water filling port, leakage water port, sewage outlet, temperature measuring port, hot water inlet and outlet, and SC-II steam heating muffler (or electric heating water heater), as well as automatic digital temperature control device, users can easily The temperature is set between 0 and 100 °C
.
The thickness of the thermal insulation layer of the hot water tank is 80mm, and the working state of the entire hot water tank is low noise and low energy consumption
.
The hot water tank comes with a tank rack
.
The hot water tank should use clean soft water, so as not to affect the heat transfer rate and water circulation rate by scale
.
4.
Steam solenoid valve rack: The steam solenoid valve rack is mainly used for heating the hot water tank.
When the hot water temperature reaches the preset value, the thermometer informs the electric control box to cut off the steam solenoid valve.
When the hot water temperature is lower than the preset value value, then open the steam solenoid valve to achieve the purpose of automatic humidity control
.
Once the steam solenoid valve fails, close the two stop valves on the left and right of the steam solenoid valve, and open the bottom stop valve to realize manual temperature control.
Overhauling and repairing the steam solenoid valve will not affect the normal operation
.
5.
Hot water pipeline pump: The hot water pipeline pump is mainly used for the hot water circulation of the hot water vacuum dryer, and the model is SGR40-6-20
.
6.
Hot water solenoid valve rack: The hot water solenoid valve rack is mainly used for the hot water inlet and cut-off function of the hot water vacuum dryer drying rack.
The hot water solenoid valve is connected with the electric control box to realize automatic control, and its function is the same as that of the steam solenoid The valve frame is similar
.
7.
Condenser: The function of the condenser is to recover the solvent in the vacuum pumping line, and the heat exchange area is 7m2, as shown in Figure 1, the e port is fed with cold water, and the f port is out of water
.
If the user has special requirements for the recovered solvent, the factory can make the condenser according to the material required by the user
.
The factory also designs and manufactures multi-pass finned copper tube condensers, the operating pressure is -0.
1 MPa ~ 0.
2Mpa, the shell is made of stainless steel, the heat exchange tube is made of red copper tubes, and the S-2F6.
5 refrigerator is matched with F- 22 is the refrigerant, and the condenser is attached with a shelf
.
8.
Storage tank: The function of the storage tank is to store the recovered solvent, which can be made according to the material required by the user.
The storage tank is equipped with a vacuum suction inlet and outlet, a solvent discharge valve port, a vent valve port, and a liquid level gauge
.
9.
Vacuum pump: For the selection of vacuum pump, please refer to the list of technical data and the configuration table of vacuum dryer system.
The appropriate vacuum pump can be selected according to the boiling point, evaporation and drying requirements of the material
.
However, in the case that the solvent does not need to be recovered, because a large amount of water vapor is contained in the vacuum dehumidification, a water ring vacuum pump or a water jet pump or a ZSL-I-100 jet vacuum pump is selected in principle
.
10.
Electric control box: It is mainly used for automatic temperature control cycle of hot water, automatic temperature control of electric heating drying rack, temperature digital display setting, manual and automatic control of vacuum pump, hot water pipeline pump, condenser, cold water circulating water pump,
etc.
11.
Baking tray: When the material to be dried allows, try to use a 10-mesh~12-mesh stainless steel mesh tray (1Cr18 Ni 9Ti), which is beneficial to the drying of the material
.
Dryer body: According to different production requirements, the dryer body can be made of A3 steel plate or A3 steel plate with 1Cr18Ni9Ti stainless steel plate or 1Cr18Ni9Ti stainless steel plate
