The invention relates to a quick coffee grading and screening device, and belongs to the technical field of agricultural production and processing. The rapid grading and screening device based on coffee comprises at least two screening devices, a visual screening system and a rack, a discharging port of the upper-stage screening device is in butt joint with a feeding port of the lower-stage screening device, and the rack is further provided with the visual screening system used for detecting and removing defective beans and impurities. Through the multi-layer sorting mechanism and elimination of the visual inspection system, one-time multi-grade sorting is achieved, sorting of coffee of different varieties is achieved, defective beans, impurities and other coffee beans difficult to sort by human eyes and machines can be detected and eliminated through the visual inspection system, whole-process automatic treatment is achieved, the screening precision can be guaranteed, and the screening efficiency is improved
