AI Technical Summary
Existing plastic granule dryers suffer from problems such as uneven hot air distribution, low drying efficiency, and high energy consumption. In particular, insufficient hot air coverage in corners far from the nozzles leads to uneven drying, and vibration and hot air circulation are independent and fail to be optimized in a coordinated manner.
The interior of the drying chamber is divided into spiral air ducts by spiral guide plates. Combined with the zoned drying design and independent air circulation components, the material turning component works in coordination with the air duct to achieve orderly circulation of hot air and precise temperature control. The material turning motor drives the material turning blades to turn the material, extending the contact time between the material and the hot air.
It significantly improves drying uniformity and efficiency, reduces energy consumption, improves material temperature uniformity, reduces defect rate, increases production capacity, improves thermal energy utilization, and reduces energy consumption.
