[0002] PVC stabilizers are additives that improve the thermal stability of polyvinyl chloride (PVC). PVC is a polymer material formed by the polymerization of vinyl chloride monomer under the action of an initiator. It has excellent mechanical properties, chemical resistance, electrical insulation, flame retardancy, and ease of processing, and is widely used in building materials, industry, agriculture, packaging, daily necessities, and medical fields. The preparation of PVC stabilizers involves manufacturing additives that improve the thermal stability of PVC materials through specific chemical and technological processes. These additives play a crucial role in the processing and use of PVC, preventing its degradation due to heat, light, oxygen, and other factors, thereby ensuring the quality and durability of PVC products. To improve the efficiency of PVC stabilizer preparation, a continuous dryer is needed; however, existing continuous dryers still have the following shortcomings:

[0003] When existing continuous dryers are in use, most of them do not have a hot air circulation structure, which leads to a relative waste of heat energy and an increase in the energy consumption of the equipment. This results in a decrease in the practicality and efficiency of the continuous dryer. Utility Model Content

After being heated by heating chamber 504, the air is sent to the interior of main body 2, where the PVC stabilizer is dried. Air duct 506 is used for the circulation of hot air inside main body 2. The front end of air duct 506 is connected to the middle of connecting pipe 503, so that hot air is reused and then delivered to the interior of heating chamber 504 for reheating before being sent to the interior of main body 2. This reduces resource waste and energy consumption, increasing the overall practicality and efficiency of the continuous dryer.

[0022] like Figures 1 to 3As shown, the main body 2 is equipped with a mixing component 6. The mixing component 6 includes a servo motor 601, a support rod 602, a mounting crossbar 603, and a tilting plate 604.
