After discharging the material, the first solenoid valve 5 is closed again, and the first heating and drying mechanism 3 can store new ABS resin material again for drying. A third solenoid valve 6 is fixedly connected to the lowest point at the left end of the resin air-drying tank 4.

The air-drying tank body 43 is fixedly connected to the hollow air pipe 84, so that it can be installed and placed.

[0035] Working principle: During use, due to the bottom planar shape of the bottom placement seat 7, it can be stably placed on an external flat ground for use. The vacuum feeding mechanism 2 is controlled by an external controller to generate a vacuum suction force. The feeding pipe 1 can suck the external ABS resin material due to the vacuum suction force generated by the vacuum feeding mechanism 2. The sucked ABS resin material can be added to the first heating and drying mechanism 3. The first heating and drying mechanism 3 can generate a drying temperature of 30 - 100 °C, which is lower than the thermal deformation temperature of the material. Thus, the first heating and drying mechanism 3 can dry the ABS resin material inside, and the first heating and drying mechanism 3 can set the required drying time through the heating control panel 34, and the drying time can be set between 1 and 1.5 hours.

After discharging, the first electromagnetic valve 5 is closed again, and the first heating and drying mechanism 3 can store new ABS resin material again for drying, effectively improving the overall drying efficiency. The air-blowing system 8 can generate wind to air-dry the ABS resin material inside the resin air-drying tank body 4 to avoid the remaining moisture. After air-drying, when the third electromagnetic valve 6 is opened, the ABS resin material inside the resin air-drying tank body 4 can be discharged to the outside through the discharge pipe 61 for collection.
