Plastic pellets are mostly cooled in a cold water tank during processing. However, after long-term use, the temperature of the cold water will rise due to heat exchange, which reduces the cooling efficiency of the plastic pellets. Moreover, after water cooling, water will remain on the plastic pellets, and the plastic pellets need to be dehydrated, which increases the work and is inconvenient for the staff to use.

[0003] Therefore, we have designed a cooling device for plastic pelletizing processing. Utility Model Content
