Introduction to the factors affecting the drying effect of the heatless adsorption dryer

　　The heatless adsorption dryer utilizes the characteristic of adsorbent to selectively adsorb certain components and adsorb the moisture in the compressed air to achieve the purpose of drying. Since the adsorbent will reach saturation equilibrium after being adsorbed for a certain period of time, it is necessary to regenerate it with dry gas to restore the adsorption and drying capacity. It uses double towers to use part of its own dry gas and reduce the pressure to close to atmospheric pressure, as regeneration gas to regenerate it, and switch between the two towers at a fixed switching time to continuously provide dry gas.
　　The heatless adsorption dryer is a product mainly suitable for drying heat-sensitive materials such as biological products, biological pesticides, enzyme preparations and other industries. Its products are only affected when the sprayed materials are sprayed into mist. High temperature and instant heating, so these active materials still maintain their active ingredients after drying.

　　In the heatless adsorption dryer, there are many factors that affect its drying effect. However, in generalization, there are mainly the following, specifically:
　　1. The inlet temperature of the drying medium: The inlet temperature mainly affects the embedding rate of the product. The determination of its value is generally determined according to the nature of the material.
　　2. Feeding speed: This is an important process parameter for spray dryers. In principle, it is required to match the feed rate with the drying capacity of the gas and equipment, so as to ensure the drying quality.
　　3. Material concentration: mainly related to some specific parameters such as the solid content of the feed. From practical experience, we can know that when the solid content of the feed is 20% to 30%, the drying effect of the dryer is very good. Moreover, increasing the solid content can improve the thermal energy efficiency, but this also has a limit range.
　　The application of the two processes of the heatless adsorption dryer can be used to make the correct choice and application in practice. The analysis and discussion of the factors affecting the spray drying effect can make us pay attention to and deal with these aspects, so as to further improve the drying effect and improve the economic benefits of the equipment.
