Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle production, and particularly relates to a plastic particle dehydrator. Background Art

[0002] During the production process, plastic particles need to be melted and squeezed out, and then cut into particles after being solidified by water cooling. There will still be moisture on the surface of the cut plastic particles, and the residual moisture will affect the quality and performance of subsequent plastic products. During the processing and molding of plastic products, if the water content is high, it will cause problems such as bubbles and thermal cracking. Traditional dehydration methods mainly use drying, centrifugal dehydration, desiccant, vacuum drying and other methods.

[0003] Although the dehydration methods currently used can achieve the purpose of dehydration and drying, the dehydration time cycle is long, and most of them require the plastic particles to be dehydrated in batches. It is impossible to directly dehydrate and dry the formed plastic particles during the production process, which greatly reduces the dehydration and drying efficiency of the plastic particles.
