The molecular sieve drying system plastic resin dryer is specifically designed to deal with engineering plastics for their high efficiency dehumidifying operations. For being indispensable dehumidifying drying equipment for the production of plastic products in their earlier stage, it is widely used in injection molding, extrusion, plastic molding and many other industries. The molecular sieve drying system is applicable to all kinds of plastic materials, such as PET, TPU, PMMA, PLA, SGP, PS, ABS, that need be dehumidified and dried.
The dehumidifier body is designed compact to save space.Different models of dehumidifiers are available for different materials and different capacity.
|Raw material||Drying time h||Drying temperature ℃||Water content before drying %||Water content after drying %||HD150||HD200||HD300||HD400||HD500||HD600||HD800||HD1000||HD1200||HD1600||HD2200||HD2600||HD3000|

External filter core, convenient for cleaning.
The condenser is easy to disassemble and to maintain.
Equip with two molecular sieve towers for alternate operation, which can stably provide the continual low dew-point dry air.
① 80mm thick insulation layer observation door, convenient monitoring.
② Wrapped with 80mm thick aluminum silicate cotton preserves the heat within and saves energy.
③ Anti-eccentric feeding device, uniform blanking, no material fault and single side blanking.
④ Complete safety measures: the top of the tank is equipped with a guardrail, and the side with a protective ladder stand.
1. The cyclone dust collector can effectively reduce the load of the return air filter and prolongs the service life of the device.
2. Stainless steel inside, equipped with independent observation window and 50mm thick asbestos insulation layer, effectively prevents heat loss.
3. The cylinder controlled built-in filter core is safe and convenient for disassembly.
4. Excellent effect of dust isolation, well guarantees the cleanliness of the material and the dust is easy to be cleaned.
The HF feeder series is equipped with a high efficiency vacuum pump with a delivery capacity of up to 1200 kg/h, the maximum conveying distance of 100 meters. It is configured with a cylinder filter which is tightly structured and combines the cyclone effect with dust separation, and is especially suitable for the delivery of dust laden materials
1. Maintenance free motor, convenient filter core cleaning.
2. Noise level is lower than 78DB (A)
3. Vertical design scheme, small covering area.
Why should you use the dehumidifying drying system?
Most engineering plastics and plastic alloy granules contain moisture content to varying degrees, and the moisture content is distributed on the surface of and inside plastic granules. If plastic granules are not properly dried, then the intrinsic quality and appearance quality of plastic products will be affected, while the processing will be more difficult. The intrinsic quality of plastic products is manifest in the significant decrease of its performance, the increase of the internal stress, easy cracking, the promotion of the polymer’s hydrolysis and degradation; the appearance quality in product yellowing, bubbling, defect, silver, markings, as well as the decrease of transparency, product cracking, inaccurate size, poor viscosity.
The presence of moisture, in injection molding and extrusion molding process results in the irregular fluctuation of the plastic melt apparent viscosity, the melt pasting passageway, occasional severe salivation, thus causing difficulties in molding. For most engineering plastics and plastic alloys, strict drying is particularly important, especially for recycled plastics, after washing, granulation and other regeneration processes, of which the moisture content is much higher than standard, and more stringent drying is needed.
