What is the drying method of dehumidification dryer?

Dehumidification dryer is a widely used drying equipment at present, which has the characteristics of high efficiency and good drying effect, and has gradually replaced the traditional hot air blower and played an important role. Gaosi Automation Technician also shared the reasons that affect the use effect of dehumidification dryer. Today, I will introduce the drying method of dehumidification dryer for you.

1, heating and drying method

Heating and drying is to use heat energy to heat materials and evaporate water in materials. Usually, air is used to dry materials. Air is preheated and sent to a dryer to transfer heat to the material. The moisture in the material evaporates at high temperature to form water vapor, which is taken out of the drying cylinder with the air. After heating and drying, the moisture in the material can be removed to reach the required moisture content of the product or raw material.

2. Chemical dehumidification method

Chemical dehumidification is to remove a small amount of water in gases, liquids and solid substances through hygroscopic agents. Because the hygroscopic agent has limited dehumidification ability, it is only used to remove trace moisture in materials, so it is rarely used in production.

3, mechanical dehydration method

Mechanical dehydration is to squeeze out a part of water by pressing the material. Commonly used methods include squeezing, settling, filtering and centrifugal separation. Mechanical dehydration usually only removes part of the free water in the material, and the combined water remains in the material. Therefore, the material will still contain moisture after mechanical dehydration, and the drying effect is not obvious. But mechanical dehydration is relatively the most economical method.

What are the drying methods of dehumidification dryer? Let's call it a day. Because in the actual production process, the moisture content of each material and the required drying effect are different, users can choose the most suitable drying method according to the situation and dehumidify and dry the material in the most effective and economical way.
