Embodiment 1
[0037] As shown in Figure 1, the compressed air in the compressed air storage tank (1) is decompressed by the pressure reducing valve (2), dehumidified by the steam radiator (5), and filtered by the filter (6), and then becomes qualified drying equipment. Air (temperature 20°C-50°C, dew point temperature -20°C-50°C) enters the flash drying host (8). Wet materials are induced by compressed air into the main unit of flash drying, mixed with warm air, dried in the main unit (8), and then enter the gas-solid separation system (11 cyclone separator, 12 dust fall chamber, 13 dust collector), Most of the solid material (about 95%) is discharged from the drying system from the cyclone separator, and the finished product is packaged; a small amount of gas fine powder material (about 5%) is intermittently discharged from the drying system from the dust drop chamber and dust collector for recycling.

Embodiment 2
[0040] As shown in Figure 1, the compressed air in the compressed air storage tank (1) is decompressed by the pressure reducing valve (2), dehumidified by the steam radiator (5), and filtered by the filter (6), and then becomes qualified drying equipment. Air (temperature 20°C-50°C, dew point temperature -20°C-50°C) enters the flash drying host (8). Wet materials are induced by compressed air into the main unit of flash drying, mixed with warm air, dried in the main unit (8), and then enter the gas-solid separation system (11 cyclone separator, 12 dust fall chamber, 13 dust collector), There are two silos under the discharge port of the cyclone separator, equipped with two butterfly valves, one of the lower silos is provided with a compressed air interface, which can be fed with compressed air for drying during operation to achieve discharge. The purpose of maintaining a certain positive pressure in the mouth. After separation, most of the solid material (98%) is discharged f...
