Standard plastic resin dryer Equipment principle

The dehumidification methods of dehumidification dryer are:
1. Dehumidification by adsorption wheel
The thin plate impregnated with hygroscopic agent is processed into a honeycomb wheel for ventilation to achieve the dehumidification effect.
2. Liquid absorption dehumidification

There are two types of liquid absorption dehumidification, one is to use the spray of lithium chloride aqueous solution to absorb water, the dew point can be reduced to about, but the equipment is larger, and the absorption liquid must be replaced; the other is to use capillary action to absorb water on the solid On the moisture absorbent, the dew point can be reduced, but the equipment will also become larger when the adsorption area is large.
3. Compression and dehumidification
Compress and cool the moist air to separate its moisture to achieve dehumidification effect. It should be noted that this dehumidification method is effective in small air volume occasions, but is not suitable for large air volume.
4. Cooling and dehumidification
The air is cooled to below the dew point, and then the condensed moisture is removed to achieve the dehumidification effect. This method is effective when the dew point is above.
The dehumidifier dryer system (compressor, evaporator, condenser) reduces the temperature of the surface cooler below the dew point temperature of the air, and a fan draws moist air into the machine for heat exchange with the surface cooler. The humid air When the water vapor is condensed and formed into water droplets, it is discharged out of the body or into the water tank in the body, and dry air is discharged into the room. This circulation reduces the indoor humidity, and the humid space achieves a dry effect.
Industrial dehumidification dryers can also choose temperature-regulating dryers, which can adjust the temperature by themselves according to the degree of dryness of the product. Heavy-duty industrial dehumidification dryers are general, but general air dehumidification and drying are also available for drying.

can dry to a moisture content below 0.02%, and solves the shortcomings of poor transparency, sprue sticking, bubbles, silver bars, cracks, poor dimensional stability, internal stress, and insufficient product physical strength. Dehumidification and drying feeding equipment series are composed of: non-heat dehumidification dryer, heat preservation type drying barrel and all stainless steel suction machine. The suction machine can transport the raw materials from the drying barrel to the forming machine, and can also transport the raw materials from the storage barrel to the drying barrel. According to customer needs, a kind of raw material can be delivered to two molding machines, vacuum motors and safety filter dust collectors are installed inside the machine. According to the production needs of different products, we can provide a powder-removing suction machine to separate the powder in the raw material and capture it. This device has a compact structure and is suitable for the production of precision injection products using engineering plastics such as connectors, precision gears, mobile phone communications, digital cameras and product size requirements, so that the moisture content of the raw materials after wet and dry is low and stable, which can meet strict requirements Technical and quality requirements.
Most engineering plastics are hygroscopic. When the plastic is taken out from the moisture-proof sealed packaging bag and exposed to the atmosphere, it will begin to absorb moisture from the atmosphere.
If it is a conventional hot-air barrel dryer, it is Humid external air can dry the plastic, so it cannot prevent the plastic from continuing to absorb moisture.
1. The internal circulation of the dehumidifier: through the operation of the compressor → discharge high-temperature and high-pressure gas through the exhaust port → enter the condenser for cooling → become a low-temperature and high-pressure gas → pass through the capillary tube → become a low-temperature and low-pressure liquid → evaporate and suck through the evaporator Heat → until the compressor becomes a low-temperature and low-pressure gas. So it goes back and forth.
2. The external circulation of the dehumidifier: under normal startup → through the operation of the fan → moist air is sucked in from the air inlet → passes through the evaporator → the evaporator absorbs the moisture in the air on the aluminum sheet → becomes dry air → Pass through the condenser to dissipate heat → blow out from the air outlet.

Dehumidifier dryerand other plastic resins must be dehumidified and dried during the production process to improve the quality of the finished product.

Standard plastic resin dryer series are mainly designed for high-efficiency dehumidification of engineering plastics with strong hygroscopicity. Using the honeycomb runner with ceramic fiber as the base material, which represents the highest technological achievements of today, as the core component, the dry air provided can easily reach -40℃ dew point, and ideally it can reach -50℃ or even lower dew point , And the dew point temperature is stable, ensuring the high quality and stability of the molded plastic products. The whole series adopts P.LD. temperature control system as standard equipment; also provides PLC control with LCD touch-sensitive human-machine interface and can monitor the dehumidification effect of the machine Dew point meter is optional, the maximum drying air volume of this product can reach 3000m3/hr. The plastic before molding must be dried to an orientation ratio of less than 0.02%, which is completely bad, sprue adhesion, burrs, bubbles, silver bars, flow marks, cracks, dimensional stability and internal stress. Product defects (for example, insufficient physical properties and strength) are caused by sufficient dehumidification of the plastic before molding. Especially for PET, PBT, PA, PC and other high water absorption plastics, drying equipment with an ultra-low dew point of -40°C is required.
Standard plastic resin dryer can be dried to a volume ratio of less than 0.02%, which solves the shortcomings of short circuit, gate adhesion, bubbles, silver bars, cracks, poor dimensional stability, internal stress and insufficient physical strength of the product. There are a lot more.
Mainly used in plastic products, automobiles, optical discs, experiments, communications, optics, etc.; the rotary honeycomb can reach a low dew point of zero bai for dehumidification and drying at -40°C. In the case of enhanced configuration, the dehumidification dew point can be as high as -50°C. It is a choice for high-precision industries.

Standard plastic resin dryer Precautions

一. Precautions for operation of desiccant dryer:
1. Make sure that the dehumidification dryer has been installed and adjusted;
2. Turn on the power switch on the control box power supply and the dehumidifier panel;
3. Check the temperature indication of the material barrel frequently, and repair it in time if any malfunction is found;
4. When the temperature rises to the specified temperature, check whether it is consistent with the temperature of the lower part;
5. Keep the barrel full at any time during production;
6. The raw materials can be produced only after the specified drying time is fully reached;
7. When the drying is completed, when the machine is to be shut down, close the feeding plate first, and then close the feeding system after pumping the bottom raw materials.
 二. Maintenance of dehumidification dryer:
1. Please confirm to provide cooling circulating water before machine operation;
2. Regularly clean the dehumidification return air aluminum mesh and the recycled motor aluminum mesh;
