By using the methods of rotary centrifugation, filter screen and upward wind force to counteract gravity, the powder is separated by particle diameter, and the filter screen can be automatically cleaned by using the cleaning brush 51 and the second motor 52. The output box 49 automatically collects the powder through the output chute 48 and can be manually drawn out later, which is convenient and efficient.

[0030] The box body 1 is provided with a main body and rollers, and the main body and the rollers are fixedly connected. Through the rollers, it is convenient to adjust the position of the device, further improving the practicality of the device.

[0031] The feeding module 2 is provided with a heater 33 located below the fluidized drying cavity 32 and a temperature sensor 34 inside the fluidized drying cavity 32. The heater 33 can heat the fluidized drying cavity 32 to facilitate the full drying of the powder, and the temperature sensor 34 can monitor the temperature to facilitate grasping the reaction state, and cooperate with the control button 62 to control the temperature in real time.

If a power outage occurs or the temporary use area is temporarily unable to connect to the external power supply, the device can use the internal battery for power supply, and the entire device can still work normally. In addition, the control unit can adjust the power of the first motor 45, the second motor 52, the third motor 47, the heater 33, the air box 22, the fan 44, and the temperature sensor 34 to adjust different stages and improve the applicability of the product.

[0036] Example 2:

[0037] When in use, the device can be first moved to the required working station, and then the electrical wire plug can be connected to an external power source or the internal power source can be used for temporary work, but attention should be paid to the power prompt on the display screen. Add powder particles into the powder bin 21, press the control button 52 to turn on the device. At this time, the air box 22 blows the powder particles, which enter the fluidized drying cavity 32 through the inlet 31. According to the temperature displayed by the temperature sensor 34 on the display screen 61, determine whether to adjust the power of the heater 33. After the powder is dried, it passes through the cyclone separator 35, and the waste gas is discharged from the box body 1 through the air holes. The powder enters the rotary separation disc 41. According to the information on the display screen 61, adjust the rotation speed of the first motor 45 and the rotation speed of the fan 44. Note that the fan 44 provides upward wind force. After screening, the powder is divided into three types. At this time, the manual control button 62 can be used to move the partition plate 46 away by using the third motor 47, or the time can be set in advance, and the three types of granular powders will reach the output cartridge 49. Then turn off the fluidizer, and the cartridge 49 can be taken out manually. If the screen needs to be cleaned during this process, the control button 62 can be used to operate the second motor 52 to move the cleaning brush up and down, or the time and power of each process can be set to make the device work in a cycle.
