A
powder material
plasma sterilizer comprises a
machine case, a feeding vibrating
bed and a discharging vibrating
bed are arranged in the
machine case, a sterilizing cavity is formed between the feeding vibrating
bed and the discharging vibrating bed, a
plasma generating device is arranged in the sterilizing cavity, the
plasma generating device comprises a positive
electrode plate and a negative
electrode plate which are symmetrically arranged in an up-down mode, a plurality of micro pipes are arranged in the sterilizing cavity between the positive
electrode plate and the negative electrode plate, feeding ports of the micro pipes are connected with a discharging port of the feeding vibrating bed through a
flow divider, discharging ports of the micro pipes are connected with the discharging vibrating bed, feeding electromagnetic clamping valves are arranged on the micro pipes close to the feeding ports, and discharging electromagnetic clamping valves are arranged on the micro pipes close to the discharging ports. By means of the plasma generating device, normal-temperature sterilization of
powder materials is achieved. By means of the micro pipes, separated sterilization is achieved, and good sterilizing effects are guaranteed. Due to the feeding vibrating bed and the discharging vibrating bed,
powder materials can flow and be conveyed. Due to the discharging electromagnetic clamping valves, the sealing performance is achieved.
