[0002] Plastic bottle flakes usually refer to a type of raw material that is sliced ​​from recycled plastic. It can be used to produce various plastic products. After purchasing the plastic bottle flakes, they first need to be cleaned and dried, and then transferred to the next device after processing so that they can be processed more efficiently.

[0003] After cleaning the plastic bottle flakes, they need to be dried. Existing drying devices for recycled plastic bottle flakes can be divided into electric heating drying devices and hot air drying devices. The electric heating drying device is a device that uses electricity as a heat source to heat and dry the material. During the drying process of recycled plastic bottle flakes, the electric heating drying device is usually used to provide heat to help remove moisture from the plastic bottle flakes, thereby improving their quality and stability. Most of the existing drying devices may cause the plastic bottle flakes to not be heated evenly during the drying process. Some areas may be overheated while other areas still contain moisture, resulting in uneven drying effects. The dust and particles generated during the drying process will accumulate inside the equipment. Long-term accumulation may cause dust accumulation problems inside the equipment, affecting the normal operation and life of the equipment. Utility Model Content
