Working principle of three machine integrated dehumidification dryer

The working principle of the three machine integrated dehumidification dryer is based on the synergistic effect of the three main functions of dehumidification, drying, and feeding. Here are the specific working principles of each function and their coordination mechanisms:

1. Dehumidification functionworking principle:-Dehumidifier: Firstly, the air passes through a preprocessing unit to remove dust and impurities. Then, the air enters the dehumidifier, usually using condensation dehumidification or adsorption dehumidification methods to reduce the humidity in the air.-Condensation dehumidification: The air passes through a cooling coil, and the temperature drops below the dew point. The moisture in the air condenses into water droplets and is discharged through a drainage system.-Adsorption dehumidification: Air passes through an adsorption tower containing a moisture absorbing agent (such as silica gel or molecular sieve), which absorbs moisture from the air and makes it dry.

2. Drying functionworking principle:-Drying machine: Drying machines typically use a hot air circulation system to heat and dry plastic pellets.-Heating: Dry air is heated to a set temperature by a heater, forming high-temperature dry air.-Circulation: High temperature dry air is sent into the drying hopper by a blower, which comes into contact with plastic particles and carries away the moisture in the plastic particles.-Dehumidification: Wet air with moisture is discharged from the drying hopper and enters the dehumidifier for further dehumidification treatment, forming a closed-loop system.

3. Feeding functionworking principle:-Feeding system: The dried plastic particles are transported to the injection molding machine or other molding equipment through the feeding system.-Vacuum feeding: Using a vacuum pump to generate negative pressure, the dried plastic particles are sucked into the feeding device through a pipeline and then transported to the injection molding machine hopper.-Pneumatic feeding: Using compressed air as power, dry plastic particles are blown into the injection molding machine hopper through pipelines.

Integrated workflow

1. Air treatment: The external air is first treated by a preprocessing unit to remove dust and impurities, and then enters a dehumidifier for dehumidification, forming dry air.

2. Hot air circulation: Dry air is heated to the set temperature by a heater, forming high-temperature dry air, which is then blown into the drying hopper by a blower.

3. Drying process: High temperature dry air comes into contact with plastic particles, taking away the moisture in the plastic particles, and humid air is discharged from the drying hopper.

4. Dehumidification regeneration: Wet air enters the dehumidifier for further dehumidification treatment, returning to dry air and continuing to circulate.

5. Feeding process: The dried plastic particles are transported to the injection molding machine or other molding equipment through a vacuum feeding or pneumatic feeding system.

Control system

-Automated control: The entire system is managed by a central control system, which can set and monitor various parameters such as temperature, humidity, pressure, etc., to ensure the stability and efficiency of the drying process.

-Sensors: Various sensors are used to monitor the operating status of the system, such as temperature sensors, humidity sensors, pressure sensors, etc., and provide real-time feedback data to the control system.

Through the above working principle, the three machine integrated dehumidification dryer achieves efficient and stable plastic material drying and feeding processes, ensuring the quality and production efficiency of plastic products.
