AI Technical Summary
In traditional pharmaceutical intermediate drying equipment, powder tends to accumulate at the bottom of the equipment, resulting in insufficient local heating, creating heating dead zones, and reducing drying efficiency and quality.
The device employs an annular electric heating plate and electric heating strips, combined with a spiral conveyor and vertical shaft drive, along with a material distribution mechanism and motor control, to achieve uniform movement of the powder within the drying drum and full contact with the heat source, eliminating heating dead zones.
It improves drying efficiency and quality, ensures that each powder is heated evenly, shortens drying time, and avoids uneven drying caused by local accumulation.
