If the laboratory freeze dryer is not cooling how to solve? Not cooling means that it can not work, but can not remove the water, the same is not the same as the boot, this is what caused it? This first check the cooling of the condenser, the general air-cooled The condenser should always clean the heat sink. The heat sink aluminum plays an important role in heat dissipation. Also check if the refrigerant is enough to see the gauge. Laboratory freeze dryer (referred to as cold dryer) Overview (classification and technical parameters)
After the air compressor is compressed, the rear cooler is cooled, the air-water separator is separated, and the compressed air after the buffer tank is regulated is generally saturated. The relative humidity is 100%, and contains impurities such as oil and solid particles. Compressed air cannot be used directly, and it needs a drying apparatus such as a laboratory freeze dryer.
The cold trap is a device for capturing moisture in the freeze drying process. In theory, the lower the cold trap temperature, the stronger the trapping ability of the cold trap, but the cold trap temperature is low, the refrigeration requirement is high, the machine cost and the operating cost are high. The cryogenic temperature of the laboratory freeze dryer is mainly about -45°C, -60°C, -80°C, and so on.
Freeze-drying with a cold trap temperature of -45°C is suitable for freeze-dried products. Freeze-drying machines with a cold trap temperature of -60°C are suitable for lyophilization of most products. Freeze-drying with a cold trap temperature of -80°C. Suitable for freeze-drying of some special products.
The effect of cold trap temperature on the catching ability of the experiment shows that the cold trap temperature drops from -35 °C to -55 °C, the water catching capacity has improved significantly, the cold trap temperature is lower than -55 °C, and the cold trap's water catching capacity is not improved obviously. Therefore, it is an ideal choice to use a cold trap temperature of about -60°C without special requirements.
The ultimate vacuum degree of the laboratory freeze dryer reflects the leakage of the freeze dryer and the pumping efficiency of the vacuum pump. The degree of vacuum in freeze-dried boxes has been considered to be as high as possible. The current view is that the degree of vacuum should be within a reasonable range. The degree of vacuum is too high, which is not conducive to heat transfer, and the drying rate is decreased. However, the ultimate vacuum degree of the lyophilized box should reach 15 Pa or more in any case.
