Abstract: A coffee hot and cold flush device comprises an upper receiving frame, a lower receiving frame, a hopper type earthen bowl, and a liquid collector. At least three support rods are connected the two receiving frame. The upper receiving frame, lower receiving frame and support rods are formed with a space having a size sufficient to receive the liquid collector. A center of the lower receiving frame has a receiving groove for placing the liquid collector. A center of the upper receiving frame is formed with an engaging hole for positioning the hopper type earthen bowl steadily. The hopper type earthen bowl has a bowl groove which is formed with a liquid guide incline. The liquid guide incline is inclined toward a middle liquid outlet. An isolating layer enclosed by filtering cloth is placed upon the liquid guide incline.

Abstract: The invention is related to a kind of device inside a grinder to peel the inner embryo membrane of coffee beans. It mainly comprises of a motor with an extruded motor shaft, a positioning cylinder located on the lateral side of a motor and equipping a lower exit inside an conveyor base, and a conveyor base, which is on the lateral side of the grinder and equips an extruded exit end on the other side of the grinder. The center of the motor extrudes a shaft connecting an eccentric synchronic rotation grinding bar. During rotation, the shaft is in a state of eccentricity, thus, the grinding surface completely hits the inner ring rim of the positioning cylinder and coffee beans are ground into particles. There is an inclined conveyor platform on the conveyor base. When grinding particles fall, due to low specific weight, the embryo membrane is sucked by a fan located on the lateral wall of a grinder and is collected in a dust collection bag.
