Infiltration drying equipment supplier china.The evaporator of the dryer can cool or dehumidify the wet air. The extracted energy can be upgraded to a higher temperature level through the heat pump and can be used to heat the dryer through the condenser.

70 ℃ in this case, hot air Infiltration drying equipment supplier china.The products in the dryer are circulated, and the hot air is used to evaporate water from the products to be dried. Therefore, the air temperature decreases and the humidity increases. After cooling, the moist air is partially discharged, however, the main part of the air is recirculated in the dryer. In order to compensate for the humid air discharged, Changzhou fanqun generally brings fresh and dry external air into circulation and preheat. After preheating, the air is mixed with recycled moist air, and then the mixture is heated to the required treatment temperature.

Infiltration drying equipment supplier china.The moist air exhausted by the dryer contains a lot of energy, and the temperature level of the air is low, so it is impossible to reuse it directly in the dryer. The application of heat pump provides the possibility of waste heat recovery. Using a heat pump, the heat extracted from the exhaust gas is upgraded to a higher temperature level and reused to heat the dryer.

Infiltration drying equipment supplier china.The dryer device indirectly heats materials with steam jacket and exhausts under high vacuum. Therefore, it is especially suitable for materials that are not resistant to high temperature and are easy to oxidize under high temperature or materials that are easy to produce powder during drying (such as various fuels), as well as materials that must be recycled for steam or solvent discharged during drying. The water content or solvent content of the dried material in the vacuum rake dryer is as high as 90%, while the low content is only 15%. The dried materials can be slurry, paste, granular, powdery or fibrous. The moisture content of these materials after drying generally reaches 0.1%, or even 0.05%.

Infiltration drying equipment supplier china.The dryer mainly has the characteristics of strong adaptability, wide application range and easy operation. It is widely used in food, medicine, chemical industry and so on.
