How to keep the bench-top type Freeze Dryer in good working condition?
Dench-top type Freeze Dryer can remove moisture from the air in the pipe. Its characteristic is that it can only reach the dew point of 2-10 degrees Celsius, and it has not reached the temperature. This is the limit value that the bench-top type Freeze Dryer can reach, because the structure of the bench-top type Freeze Dryer uses refrigerant to cool. If it is too cold, it will easily be frozen. Ice. It is correct, the adsorption is better, it can reach negative pressure dew point, and it can work normally in colder environments.
The use of desktop freeze dryers has a certain service life. How can desktop freeze dryers keep a good working condition at all times? This is a question of concern to everyone and a problem that bench-top type Freeze Dryer manufacturers have been studying. Briefly analyze this problem.
The refrigeration system is the core component of the desktop freeze dryer, because the bench-top type Freeze Dryer operates on the principle of freezing. In the refrigeration system, the refrigeration compressor is the power source and heart of the desktop freeze dryer. In order to ensure the reliable and stable operation of the commodity and prevent the compressor from leaking fluorine, a high-quality refrigeration compressor should be selected. In order to maintain the refrigeration compressor, the user must prevent the refrigeration compressor from being subjected to fierce collision, oscillation and overturning during the operation.
Refrigerant is a material that can be recycled in desktop freeze dryers. In most cases, there will be a small loss when the refrigerant is recycled. Therefore, the refrigerant pressure of the bench-top type Freeze Dryer should be checked frequently during the use of the equipment. It is detected whether the current refrigerant is sufficient. If it is found that the refrigerant is insufficient, the refrigerant should be filled to avoid unnecessary impact. Because the high pressure of the refrigerant in the bench-top type Freeze Dryer can reach more than 15 kg, the piping system in the refrigeration system works at high pressure at this time. The copper pipeline part of the bench-top type Freeze Dryer needs to bear higher pressure. If there are large particles hitting the evaporator tubes in the internal evaporation tube at this time, it may cause damage to the copper tubes of the evaporator. It is difficult to repair the damage caused by the internal structure of such evaporators. Try to avoid such situations.
In order to reduce the occurrence of internal leakage in the evaporator, it is recommended to install a primary precision filter at the front of the desktop freeze dryer, which can filter particles such as primary dust and prolong the life of the desktop freeze dryer. It is also necessary to periodically replace the precision filter element and use a bench-top type Freeze Dryer The machine keeps working effectively for a long time.
