Description

Technical Field

[0001] This utility model relates to drying equipment technology, specifically a drying equipment for the production and processing of plastic particles. Background Technology

[0002] Plastic products are now widely used in various industries. The large-scale use of plastic products has led to a surge in the supply of raw material plastic particles. The production and processing of plastic particles requires many steps, among which the drying process requires the use of a Hong'an device to dry the plastic particles.

[0003] Existing drying equipment for plastic particles is a double-cone rotary dryer. This type of dryer creates a vacuum environment on the inner wall and uses a vacuum pump to extract the humid gas and liquid produced during drying, separating them from the plastic particles themselves, thus achieving a rapid drying effect. However, during use, some particles inevitably adhere to the inner wall of the drying drum, which is troublesome and time-consuming to clean, thus delaying production efficiency. Therefore, we propose a drying equipment for plastic particle production and processing to solve the above-mentioned problems. Utility Model Content
