Refrigeration Air Dryers

Product Characteristics

● R22 refrigerant and tube heat exchanger are used for more than 80 cubic meters; the gas-liquid separator adopts a patented three-stage separation method of "direct collision separation, low-speed centrifugal separation and stainless steel wire mesh demisting separation", which will remove 99.9% of the liquid The moisture is separated from the cooled compressed air to prevent the secondary evaporation of moisture and ensure the low dew point quality of the finished gas;

Working Principle

The air-cooled freezer dryer is a widely used, highly efficient and energy-saving device for drying materials, such as pharmaceuticals, chemical products, food, and fruit. Its working principle is based on the process of sublimation, which involves the transformation of a solid substance from a frozen state to a gaseous state without passing through a liquid state.

The air-cooled freezer dryer contains a refrigeration system, a vacuum system, and a heating system. Firstly, the refrigeration system cools the drying chamber to a low temperature, typically between -20℃ to -60℃, to create an environment that facilitates sublimation. Secondly, the vacuum system removes the moisture from the material in the drying chamber. Thirdly, the heating system warms the material to increase the sublimation rate. During the sublimation process, the moisture contained in the material turns into water vapor, which is pumped out of the drying chamber by the vacuum pump. The water vapor is then condensed by the condenser and discharged outside the system.

The air-cooled freezer dryer has many advantages, such as low energy consumption, high thermal efficiency, and easy operation. It also avoids the tedious process of melting the dried material and removing the moisture by squeezing, which can cause damage to the product. Additionally, the air-cooled freezer dryer has a compact structure, which reduces the floor space needed and facilitates transportation.

In conclusion, the air-cooled freezer dryer is a reliable and efficient device for the drying of materials. It has been widely used in various industries, and its application is expected to expand continuously. With the continuous development of technology, we believe that air-cooled freezer dryers will become a more sustainable and environmentally friendly solution for the drying of materials.
