[0020] Working principle: First, connect the entire device to an external power source, then pour coffee beans from the feed hopper 11 and make them enter the vibrating screen 5. The vibration of the vibrating screen 5 will gradually move the beans toward the end of the vibrating screen 5 to achieve the purpose of screening. During this process, the coffee beans will enter the cleaning chamber 2, the drying chamber 3 and the air separation chamber 4 in sequence. When in the cleaning chamber 2 on the vibrating screen 5, the cleaning liquid at the bottom of the cleaning chamber 2 can be extracted by the water pump 26, and then sprayed from the nozzle 25 to the coffee beans to clean the dust and impurities on the surface. When the water returns to the bottom of the cleaning chamber 2, it will be filtered by the dust removal filter cloth 22 to achieve the recycling of the cleaning liquid and And after the loss of cleaning liquid causes the liquid level to drop, the water replenishing pipe 21 can also be used to replenish the cleaning liquid. Then, the coffee beans enter the drying chamber 3, and the heating of the heating plate 32 is used to increase the internal temperature of the drying chamber 3, so that the cleaning liquid on the surface of the beans evaporates quickly, and finally enter the air selection chamber 4. The coffee beans will fall from the vibrating screen 5, and the air flow is generated by the fan 45. Since the weight of the gravel is greater than the weight of the coffee beans, they will fall to the inside of the partition 43 and be discharged through the gravel discharge port 42, while the coffee beans will fall to the outside of the partition 43 and be taken out through the coffee bean discharge port 41, completing the entire screening operation. The operation is more convenient and the processing efficiency is improved.
