Problems solved by technology

[0002] The refrigerated dryer uses physical principles to freeze the moisture in the compressed air below the dew point, so that it can be separated from the air. The air dryer is limited by the freezing point temperature of water. In theory, its dew point temperature can be close to 0. According to the actual situation, the dew point temperature of a good freeze dryer is generally about 5 degrees, and the dew point is generally not stable enough. The existing freeze dryer is not convenient for users to use, which reduces the practicability of the equipment. Therefore, we Provide a refrigerated cycle dryer

Abstract

The invention belongs to the technical field of dryer equipment, and relates to a circulating freeze dryer. The circulating freeze dryer comprises a water tank, an evaporator is arranged in the watertank, a water outlet end of the evaporator is connected with a third pipeline, a water outlet end of the third pipeline is connected with a compressor, a water outlet end of the compressor is connected with an air-cooled condenser, a water outlet end of the air-cooled condenser is connected with a fifth pipeline, a water outlet end of the fifth pipeline is connected with an expansion valve, and awater outlet end of the expansion valve is connected with a sixth pipeline. The circulating freeze dryer can reduce the temperature of air to be lower than a dew point through a cold water circulationsystem, so that moisture is separated out of the air, and the air is dried.

Description

technical field [0001] The invention belongs to the technical field of dryer equipment, and relates to a circulating freeze dryer. Background technique [0002] The refrigerated dryer uses physical principles to freeze the moisture in the compressed air to below the dew point, so that it can be separated from the air. The air dryer is limited by the freezing point temperature of water. In theory, its dew point temperature can be close to 0. According to the actual situation, the dew point temperature of a good freeze dryer is generally about 5 degrees, and the dew point is generally not stable enough. The existing freeze dryer is not convenient for users to use, which reduces the practicability of the equipment. Therefore, we Provided is a refrigeration cycle dryer. Contents of the invention [0003] The present invention aims at the above problems, and provides a circulating freeze dryer, which reduces the air temperature to below the dew point through a cold water circu...
