AI Technical Summary
Existing drying equipment often results in uneven heating and particle accumulation when drying plastic granules, leading to poor drying performance.
The system uses a vibrating motor and connecting spring in conjunction with a feeding sloping plate to ensure that the plastic granules fall evenly. The granules undergo multiple drying processes through a dehumidification component and a conveying auger. Combined with a dehumidification box and absorbent cotton, the system removes moisture and impurities from the hot air, thus improving the drying effect.
This method achieves uniform heating of plastic granule raw materials, improves drying efficiency, saves resources, and enhances the practicality of the drying equipment.
