As a technical optimization scheme of the invention, the bottom of the driving shaft 2 penetrates through the inner wall of the box body 1, and the bottom of the driving shaft 2 is fixedly connected with the output end of the driving motor.

The working principle is as follows: in use, coffee beans are first placed into the housing 1 from the hopper 23, the beans roll from the first cavity 5 towards the center, then fall onto the first sieve plate 3, then the driving motor drives the driving shaft 2 to rotate, the driving shaft 2 drives the first toothed ring 4 to rotate through the driving gear 29 and the intermediate gear 28, the first toothed ring 4 drives the first scraping plate 7 to rotate, the first scraping plate 7 rotates on the first sieve plate 3, coffee beans with the size smaller than that of the through groove 25 fall below the first sieve plate 3 through the through groove 25, part of coffee beans clamped in the through groove 25 on the first sieve plate 3 extrude the buffer plate 27 under the scraping action of the first scraping plate 7, the buffer plate 27 extrudes the return spring 30, so as to increase the space in the through groove 25, and make the clamped coffee beans fall below the first sieve plate 3, and part of the coffee beans with the volume larger than the inner diameter of the through groove 25 can be scraped into the first collecting box 8 by the first scraper 7 through the collecting groove 9;

coffee beans falling below the first sieve plate 3 pass through the first convex plate 11 and the second concave plate 14 and then fall onto the second sieve plate 12, because the aperture of the through groove 25 on the second sieve plate 12 is smaller than that of the through groove 25 on the first sieve plate 3, and the rest structure of the second sieve plate 12 is the same as that of the first sieve plate 3, after coffee beans pass through the same operation on the second sieve plate 12 as that on the first sieve plate 3, part of coffee beans larger than that of the through groove 25 on the second sieve plate 12 enter the second collection box 17, and coffee beans smaller than that of the through groove 25 on the second sieve plate 12 enter the third collection box 18 after passing through the second convex plate 16; first collection box 8, the case is collected to the second 17 and the third 18 all communicates the case of toasting, control by the staff, first collection box 8, the second is collected box 17 and the third and is collected the size of the coffee beans in the box 18 is collected to solitary one and all the same basically, and first collection box 8, the second is collected the coffee beans size of box 17 and the third in collecting the box 18 and is for by big-end-down, separate not unidimensional coffee beans and save, avoid not unidimensional coffee beans to toast together, it is different to cause the maturity, thereby influence the off-the-shelf quality of coffee beans.

When coffee beans enter the box body 1, the first air blowing port 19 and the second air blowing port 20 both blow out hot air to preheat the coffee beans, so that the roasting time of the coffee beans after entering the roasting box is reduced, and the roasting efficiency is increased;

when coffee beans pass through the first convex plate 11 and the second convex plate 16, part of impurities contained in the coffee beans enter the first convex plate 11 and the second convex plate 16 from the impurity holes 33 on the first convex plate 11 and the second convex plate 16; and more impurities enter the impurity holes 33 through the gathering of the first concave plate 5 and the second concave plate 14; when the partial impurities pass through the first sieve plate 3 and the second sieve plate 12, the partial impurities are retained in the ash storage groove 24, so that the impurities in the coffee beans are further reduced; when the coffee beans pass through the second air blowing port 20, the air blown out by the second air blowing port 20 can blow dust and small particle impurities in the coffee beans to the filter screen 22 through the air blowing groove 21, so that the impurity content in the coffee beans is ensured to be low, and the quality of finished coffee beans is prevented from being influenced;

after the roasting process of the coffee beans is finished, the driving motor is reversed to drive the first scraping plate 7 and the second scraping plate 15 to be reversed, the stop blocks 26 at the bottoms of the first scraping plate 7 and the second scraping plate 15 are respectively abutted to the corresponding baffle plates 34, the baffle plates 34 are abutted to the stop blocks 26, the stop blocks 26 drive the rotating shaft 31 to rotate, the cleaning brush 32 is moved to be matched with the ash storage groove 24, dust and impurities in the ash storage groove 24 are cleaned out, at the moment, the first air blowing port 19 and the second air blowing port 20 work to blow dust onto the filter screen 22, and the first sieve plate 3 and the second sieve plate 12 can be cleaned after the roasting process is finished.

For the process of impurity collection, the conventional coffee bean impurity removal usually adopts a screen to perform multiple-pass, coffee beans with various sizes are mixed together, due to the limitation of the sizes, some impurities can not be sufficiently removed easily, and fine dust impurities can be easily attached to the outer part of the subsequent coffee beans. If high-performance dust removal equipment is adopted, the cost is higher. In the invention, the collection of the impurities is only carried out in the process of classifying and screening the coffee beans, and some impurities in the coffee beans are removed in an auxiliary way. Because the setting of first concave plate 5 and second concave plate 14 can be concentrated the coffee beans and drop downwards, the subsequent screening of being convenient for with the help of the dispersion of the first protruding board 11 of below and second protruding board 16, utilize the hole on first protruding board 11 and the second protruding board 16 to carry out impurity collection simultaneously, the coffee beans after concentrating together the friction fall below for tiny impurity after concentrating can be convenient for collect. And impurities are removed in a sequential manner in classification, so that the subsequent impurity removal process can be omitted, the processing steps can be saved, and the production cost can be reduced. Utilize the first blast orifice 19 of top to blow the air current downwards, can accelerate impurity downstream and drop, can make coffee beans pass through second blast orifice 20 simultaneously, the wind that second blast orifice 20 blew out can blow dust and the tiny particle impurity in the coffee beans to filter screen 22 by air-blowing groove 21 on, has guaranteed that the impurity content in the coffee beans is less, avoids influencing the off-the-shelf quality of coffee beans. The first tuyere 19 and the second tuyere 20 work cooperatively, so that the impurity removal of coffee is more efficient and the cost is lower.
