There are many factors that affect the drying efficiency of drying equipment, mainly including the following aspects:

Drying temperature: heat is the key to open the resultant force between water molecules and hygroscopic polymers. When the temperature is higher than a certain value, the attraction between water molecules and polymer chains will be greatly reduced, and water vapor will be carried away more easily by dry air. However, too high temperature may also lead to poor material quality or other adverse effects.

Dew point: Dew point means that wet air is first removed during the drying process, so that it contains very low residual moisture. By heating air to reduce its relative humidity, the steam pressure of dry air is lower.

Characteristics of raw materials: Physical and chemical characteristics of raw materials, such as particle size, viscosity, water content and solubility, will directly affect the drying speed and product quality.

Conditions of drying gas: The temperature, humidity and flow rate of drying gas play an important role in drying effect. Suitable drying gas conditions can effectively promote the evaporation of water and the drying of materials.

Performance of spray system: The performance of sprayer directly affects the drying effect, and it should be able to atomize liquid raw materials into small particles evenly and carefully, and fully contact with drying gas.

Structure and design of drying chamber: the structure and design of drying chamber determine the flow mode of drying gas and materials, such as the shape and size of drying chamber, the position and arrangement of sprayer and other factors will affect the drying degree of materials.

Drying time and speed: drying time and speed are closely related to drying effect. Appropriate drying time and speed can ensure that the materials are fully dried and avoid excessive drying or insufficient drying.

Stirring: For some materials, proper stirring can promote the contact between materials and drying gas and improve the drying effect.

Dust treatment: the dust generated in the drying process may affect the drying effect. Proper dust treatment measures can ensure the cleanliness of dry gas and the quality of materials.

In addition, there are other factors, such as poor ventilation, poor quality of drying box, damaged adsorption materials, etc., which may also affect the drying efficiency of drying equipment. Therefore, in order to improve the drying efficiency of drying equipment, it is necessary to comprehensively consider these factors and make reasonable control and optimization. The specific adjustment and optimization should be carried out according to the actual application and material characteristics.
