Automatic dehumidification dryer is a device used in industrial production to remove moisture from raw materials. Its basic principle is to use a dehumidifier to remove moisture from the air, then place the raw materials in a drying chamber, evaporate the moisture in the raw materials into water vapor through heating, and finally condense it into water droplets through a condenser and discharge them outside the machine, thus achieving the drying effect of removing moisture from the raw materials. This article will provide a detailed introduction to the classification, working principle, characteristics, application fields, usage precautions, and future development trends of automatic dehumidification dryers.

1、 Classification of Automatic Dehumidification and Drying Machines

According to different classification criteria, automatic dehumidification dryers can be classified into multiple types. Among them, according to different drying methods, it can be divided into freeze dryer and heating dryer; According to different dehumidification methods, it can be divided into adsorption dehumidifiers and rotary dehumidifiers; According to the different structural forms, it can be divided into box type dehumidifiers and pipe type dehumidifiers.

2、 Working principle of automatic dehumidification dryer

The working principle of an automatic dehumidification dryer is mainly to remove moisture from the air through a dehumidification system, then heat the raw materials to the required processing temperature through a heating system, and finally transport the dried raw materials to the processing equipment for processing through a feeding mechanism. The specific process is as follows:

1. Dehumidification system: The automatic dehumidification dryer uses adsorption dehumidification or rotary dehumidification methods to remove moisture from the air. Adsorption dehumidifiers absorb moisture from the air using adsorbents such as silicone and alumina, while rotary dehumidifiers expel moisture from the air by rotating the wheels.

2. Heating system: The automatic dehumidification dryer uses heating to heat the raw materials to the desired processing temperature. Heating systems generally use steam, hot water, thermal oil, and other heating media.

3. Feeding mechanism: The automatic dehumidification dryer transports raw materials to the drying room through the feeding mechanism. The feeding mechanism generally adopts methods such as belt conveyor and screw conveyor.

3、 Characteristics of automatic dehumidification dryer

1. Efficient and energy-saving: The automatic dehumidification dryer can quickly remove moisture from the air, improving production efficiency while saving energy.

2. Temperature controllable: The automatic dehumidification dryer can control the processing temperature of raw materials through a heating system to meet different processing needs.

3. Environmental protection and energy conservation: The automatic dehumidification dryer adopts heat recovery technology, which can recover the heat generated from the exhaust gas during the heating process, reducing energy consumption and emissions.

4. Strong adaptability: The automatic dehumidification dryer can adapt to different types and moisture contents of plastic raw materials, and has a certain degree of flexibility.

5. Stable operation: The automatic dehumidification dryer adopts advanced control system and high-quality components to ensure the long-term stable operation of the equipment.
