By adopting new plastic materials, medical devices can be made safer and more environmentally friendly. PVC is a commonly used material in medical materials. When producing medical PVC granules, the extruded medical PVC strips need to be cooled and shaped through a water tank. The cooled medical PVC strips need to be dried, and finally the dried medical PVC strips are cut into medical PVC granules.

[0003] In the Chinese patent with the publication number CN219618461U, a strip drying machine with a shaping device for plastic granule production is mentioned. The cold water in the shaping water tank is used to cool and shape the strips, and the cooling box can circulate and refrigerate the water in the shaping water tank to ensure the shaping effect of the strips and achieve the purpose of saving water. Moreover, grooves are evenly arranged on the surfaces of the first guide roller and the second guide roller in the shaping water tank, and the grooves can separate adjacent strips to prevent the strips from sticking together.

[0004] The following defects exist in the granule drying machine in the above-mentioned prior art:

[0005] 1. The water receiving tank is located below the air outlet of the hot air blower. When the hot air blower dries the plastic strips, a large amount of water vapor is generated and difficult to disperse. The water vapor adsorbs on the plastic strips, affecting the subsequent processes.

[0006] 2. The plastic strips soaked and cooled for shaping are not processed before drying and are directly conveyed into the drying equipment. There is too much residual water on the surface of the plastic strips, making it difficult to dry quickly. Content of the Utility Model

[0007] The purpose of the utility model is to provide a drying machine for medical PVC granule production to solve the problem in the prior art that when the hot air blower dries the plastic strips, a large amount of water vapor is generated and difficult to disperse, and the water vapor adsorbs on the plastic strips, affecting the subsequent processes.
