Hopper Dehumidifing dryer Equipment principle

Hopper Dehumidifing dryer 1. Adopt a high-performance hot air diffusion device that evenly disperses hot air to keep the plastic drying temperature uniform and increase drying efficiency.
2. The special hot air elbow design can avoid the accumulation of dust on the bottom of the electric heating tube and cause burning.

3. All kinds of dehumidification dryer models can provide preheating timing device, microcomputer control, and double-layer insulation barrel selection.
4. The material barrel and internal parts are all made of stainless steel, and the material barrel is separated from the bottom, which is convenient for material cleaning and rapid material change.
5. The proportional deviation indicating temperature controller is used to accurately control the temperature.
6. There are double overheating protection devices, which can reduce accidents caused by man-made or mechanical failures.
7, 0-99 hours timed automatic startup, providing intermittent drying method to achieve the purpose of power saving.
  The working principle of this basic solution is: pour the cleaned and crushed plastic into the feeding box, start the motor, and the motor drives the first fan to rotate. When the first fan rotates, a large amount of airflow is generated, and the airflow gradually removes all plastic Blow into the spiral tube. Open the valve, the dry powder falls into the spiral tube, the airflow will blow the dry powder and the plastic at the same time, when the absorbent powder comes in contact with the water on the plastic, it will absorb the moisture. The output end of the motor can also drive the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the gear shaft and the worm on the gear shaft to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the rotating ring to rotate. When the plastic passes through the rotating ring with elastic strips, the elastic strips in the rotating ring will brush to the plastic and make the plastic rotate to change the direction, so that every surface of the plastic can contact with the dry powder and get dried. When the plastic passes through the rotating ring with a brush, the brush can brush off the dry powder contaminated on the plastic, and separate the plastic from the dry powder.

Hopper Dehumidifing dryer application

Since most engineering plastics are hygroscopic, coupled with the influence of weather and regional climate, it is easy to cause the plastic pellets to be excessively wet and fail to achieve the molding effect. In addition, the plastic raw materials are different in the previous granulation process, so the air moisture content and hygroscopicity are also different. Therefore, when molding, it is easy to produce bubbles, silver bars, poor transparency, cracks, and poor stability, which seriously affect product quality. The air pipeline of the desiccant dryer adopts a closed circulation system, which can not be affected by the external weather. The material can be dried well in dry weather or wet weather, without reversing moisture, and the product quality is high.
The desiccant dryer first draws the air in the environment to remove the moisture in the air under low dew point, and then heats the dried air into one or more standard drying hoppers, which can improve the drying efficiency and shorten the drying time. If a traditional hot air blower uses moisture with external air to dry the material, it is difficult to achieve the drying effect. In addition, when the plastic is taken out of the moisture-proof sealed packaging bag and exposed to the atmosphere, it will begin to absorb moisture from the atmosphere. Traditional hot air blowers cannot prevent the plastic from continuing to absorb moisture, and the drying effect is poor.Hopper Dehumidifing dryer,Hopper desiccant dryer, European style desiccant dryer, vacuum dryer
Especially suitable for engineering plastic materials with strong moisture absorption. Such as PA, PET, PC, PBT, etc., among which optical-grade GCD-OP models can be used in the manufacturing process of optical-grade products such as lenses, LCD light guide plates, optical discs, etc., under ideal conditions the lowest dew point can reach -40℃ .

Hopper Dehumidifing dryer Precautions

Hopper Dehumidifing dryer Maintenance and maintenance of hopper desiccant dryer:
(1) Ensure that the hot air is clean.
(2) Measures should be taken to prevent coke dust and avoid backflow of hot air.
(3) For viscous materials, measures should be taken to minimize wall sticking.
(4) The exhaust air temperature is not allowed to exceed the requirements to ensure product quality and safety.
(5) During the drying process of the material, all parts of the equipment in contact with the material must be easy to clean and sterilize.
(6) In order to improve the solubility, instant solubility, and dry products, they should be continuously discharged from the drying chamber quickly and packaged after cooling.
