The impurities pass through the filter cylinder and are discharged. The air supply mechanism is started, so that the outside air enters the cavity and is blown onto the coffee beans inside the filter cylinder through multiple air outlets, further separating the impurities from the coffee beans, improving convenience. After the impurities are cleaned up, the motor makes the feeding mechanism under the filter cylinder, and the coffee beans inside the filter cylinder are discharged through the feeding mechanism, improving convenience.
