standard injection molding dryer Equipment principle

Standard Dehumidifying Dryer
The standard plastic resin dryer is the most effective and economical model for drying plastic raw materials. It can dry raw materials that are wet due to packaging, transportation or recycling.
The hopper is made of stainless steel, with the functions of "hot air blowing down" and "cyclone exhaust" as well as a double-layer insulation barrel, which is especially suitable for drying engineering plastic materials with a dehumidifier.

The air blown by the drying fan becomes high-temperature dry air after drying and electric heating. Through the unique design of the lower blowing pipe, the hot air is evenly dispersed in the insulation barrel to dry the raw materials; the hot air recovery device is optional, and the air blown out is filtered and then dried The wind blows out, forming a closed loop.
Drying and dehumidifying part: The hot and humid air returned from the drying barrel is cooled and blown into the honeycomb runner. The moisture in the air is adsorbed by the runner and then desorbed by the regeneration heating air. The two airflows act on the runner at the same time, and with the rotation of the runner, the moisture in the air is continuously adsorbed and then desorbed by the regeneration air to be discharged, forming a stable low dew point air, which is heated to the plastic The drying temperature is blown into the drying barrel to form a closed cycle to dry the raw materials.
Suction part: Suction material is sucked into the dry bucket from the storage bucket or other storage container. When the reed switch of the vacuum hopper detects that there is no material, the suction motor runs to generate vacuum in the vacuum hopper. The raw materials in the bucket are sucked into the vacuum hopper due to the air pressure difference. When the suction time is completed, the suction motor stops running, and the raw materials fall into the drying bucket due to their own weight. The dried raw materials are pumped from the drying barrel to the photoelectric hopper or micro-motion hopper installed in the plastic molding machine.

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. standard injection molding dryer 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. standard injection molding dryer 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.

Plastic resin dryers can be widely used in civil air defense engineering, tobacco factories, pharmaceutical factories, scientific research, industry, medical and health, instrumentation, commodity storage, underground engineering, and computer rooms, archives, warehouses and other high humidity places to prevent instruments, meters, Computers, telecommunications equipment, medicines, materials, etc. are damaged by moisture, rust, and mildew. It can work normally when the relative humidity of the environment is within the range of 35-95% and the ambient temperature is 5-38 degrees Celsius. It is mainly used in basements, archives, precision instrument rooms, workshops and warehouses of pharmaceutical factories, electronic factories, industry, storage, etc., which require high relative air humidity. It can improve product quality, humidity hazards, and mold hazards. Everywhere in daily life. Therefore, it is necessary to add dryers to the above-mentioned environment. standard injection molding dryerWith the widespread use of engineering plastics, Dehumidifying dryers have gradually replaced traditional hot air dryers.

standard injection molding 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.
