[0025] The conveying pipeline 3 is provided with an air electric heater 5, an air sterile filter 4, a high-pressure blower 2 and a dehumidifier 1 in sequence from the side closest to the storage silo 8 to the side furthest from the storage silo 8.

[0029] The buffer tank 17 is equipped with a material temperature sensor 27.

[0031] The working principle and operation process of this utility model are as follows:
[0032] First, air processed by dehumidifier 1 is drawn in by high-pressure blower 2 and fed into sterile air filter 4 via conveying pipe 3. The sterile air filter 4 then feeds the filtered air into electric air heater 5 for heating. The heating temperature range is 40–130℃. A high-precision temperature controller 6 precisely controls the air heater according to the required material reheating temperature, which ranges from 15–35℃. Then, the ultra-low temperature material is pulverized and fed into storage silo 8 via inlet. The material is conveyed by feed screw 10 and fed through three-way inlet 11 into mixing and heating pipe 12, where it mixes with dry, sterile, high-temperature air for rapid reheating. The reheated material then enters the first conical separator 14 via separator inlet 13 for gas-powder separation. Heavier powder particles fall to the bottom of the first conical separator 14, while gas containing a small amount of powder enters the second conical separator 15 via separation exhaust pipe 21 and connecting pipe 22 for further separation. The pneumatic butterfly valve 16 is opened to allow the gas to fall into the first and second conical separators 14. 5. The material at the bottom enters the buffer tank 17, then enters the vibrating screen sealing housing 20 and falls onto the linear vibrating screen 19. The linear vibrating screen 19 disperses the agglomerated material and spreads it evenly on the inner wall surface of the linear vibrating screen 19, causing the material to move towards the material outlet 28. The infrared heating lamp 24 on the inner wall of the vibrating screen sealing housing 20 is activated to heat and reheat the material spread on the inner wall of the linear vibrating screen 19 evenly. A dust discharge pipe 25 is also provided at the top of the vibrating screen sealing housing 20 near the material outlet 28 to prevent dust from being generated during the operation of the linear vibrating screen 19 and causing pollution to the production area.
