[0001] The utility model relates to the technical field of drying equipment, in particular to a drying device for producing medical PVC pellets. Background Technique

[0002] When preparing medical PVC pellets, the cold cutting method is generally adopted. The cold cutting method means that the material after being mixed, plasticized by an extruder forms a sheet material from the forming die in front of the barrel, first falls into a water tank to cool down and then is coiled, and then is cut into pellets by a special pelletizer. Therefore, the material enters the pelletizer with cooling water on its surface, and the pellets after cutting have a large amount of moisture that needs to be dried.
