What Types of Dehumidifying Dryer Can Be Classified by Pressure?

The dehumidifying dryer is a large-scale machinery widely used in industrial production. The most common way to dry materials with a dehumidifying dryer is through pressure, which can be divided into two categories: atmospheric pressure dehumidifying dryer and vacuum dehumidifying dryer. Both types of dehumidifying dryers are frequently used in industrial production by industrial enterprises.

Classification of dehumidifying dryer by pressure

Atmospheric pressure dehumidifying dryer

An atmospheric pressure dehumidifying dryer can meet the drying needs of various industries or the humidity requirements of different production materials required by different enterprises. It has a wide range of applications and can be used in various industrial productions, making it very versatile. Therefore, the technology of atmospheric pressure dessicant dryer is the most mature among all drying technologies.

Vacuum dehumidifying dryer

Compared with an atmospheric pressure dessicant dryer, the vacuum dehumidifying dryer is more accurate. Under vacuum operation, the vapor pressure of the moisture in the material space can be reduced, thus speeding up the drying process of the material. In the drying process, the boiling point of the moisture in the material can be lowered, and the temperature of the material can be more precisely controlled. In addition, the moisture generated during the operation of the dryer is less likely to leak out due to the vacuum environment.

Atmospheric pressure dryers can be used in many occasions, while vacuum dehumidifying dryers are more suitable for drying materials that are prone to allergies, oxidation, explosion, and toxicity. They can also be used in situations where humidity needs to be recovered. Therefore, the scope of application of vacuum dryers is not very wide.

Maintenance methods of dehumidifying dryer

• Suitable indoor temperature: The dehumidifying dryer works best at an indoor temperature of around 12°C to 35°C. If the indoor temperature is lower than 12°C, the humidity in the air is already very low. To avoid excessive drying and discomfort, it is not recommended to use a dehumidifier in this case.

  
  

• Pay attention to the place of placement and use: Do not use it in a too enclosed and narrow space. If there are items or walls around, keep them at a distance of more than 50 cm. Also, do not use it in places with a lot of oil fumes, as it may cause damage to the heat exchanger.

  
  

• After the dehumidifying dryer is turned off, do not start it immediately. Wait for three minutes before restarting to extend the service life of the compressor. Most new dehumidifiers have a self-protection function so that pressing the start button immediately after turning off may not work, which is normal.
