Embodiment 1

[0049] Embodiment 1: as Figure 1~5 As shown, a coffee bean classifier includes a feeding part 1, an even material screening part 2, a classifying part 3, an air blowing part 4, a receiving part 5, an electric control box 6, an air pump 7, and the feeding part 1 and The even material screening part 2 is connected,

[0050] The feeding part 1 includes a frame I8, a hopper 9, a vibration motor I11, and an impurity collector I12. The frame I8 is a rectangular frame structure. The top of the hopper 9 is installed on the top of the frame I8 through the hopper installation component 10, and the lower part of the hopper 9 extends In the frame I8, the vibration motor I11 is fixed on the side wall of the hopper 9, the impurity collector I12 is fixed horizontally on the bottom of the frame I8, and the discharge port 14 of the hopper 9 is installed obliquely on the side of the bottom of the hopper 9. The lower end of the wall and the discharge port 14 communicates with the even material...

Embodiment 2

[0060]Embodiment 2: A kind of method for classifying coffee beans, coffee beans are green coffee beans, classify according to the particle diameter of coffee beans, adopt the coffee bean classifier of embodiment 1 to classify, concrete steps are as follows:

[0061] (1) Put the coffee beans into the hopper of the feeding part, and realize the preliminary screening under the vibration of the vibration motor Ⅰ. The pre-screened adulterants pass through the bottom screen Ⅰ at the bottom of the hopper and enter the adulterant outlet. The impurities fall into the adulterant collector Ⅰ through the adulterant outlet under the action of gravity, and the preliminary screened coffee beans stay above the bottom screen Ⅰ and pass through the outlet of the hopper under the vibration and gravity of the vibration motor Ⅰ Enter the main body of the vibrating bed in the leveling and screening part;

[0062] (2) The pre-screened coffee beans in the vibrating bed main body of the homogenizing a...

Embodiment 3

[0065] Embodiment 3: A kind of coffee bean classification method, coffee beans are roasted coffee beans, carry out classification according to the color of roasted coffee beans, adopt the coffee bean classification machine of embodiment 1 to carry out classification, concrete steps are as follows:

[0066] (1) Put the coffee beans into the hopper of the feeding part, and realize the preliminary screening under the vibration of the vibration motor Ⅰ. The pre-screened adulterants pass through the bottom screen Ⅰ at the bottom of the hopper and enter the adulterant outlet. The impurities fall into the adulterant collector Ⅰ through the adulterant outlet under the action of gravity, and the preliminary screened coffee beans stay above the bottom screen Ⅰ and pass through the outlet of the hopper under the vibration and gravity of the vibration motor Ⅰ Enter the main body of the vibrating bed in the leveling and screening part;

[0067] (2) The pre-screened coffee beans in the vibr...

Abstract

The invention relates to a grader for coffee beans and a grading method, and belongs to the technical field of agricultural material sieving equipment. The grader for coffee beans comprises a feedingpart, a material evening sieving part, a grading part, an air blowing part, a collecting part, an electric control box and an air pump, wherein the feeding part is communicated with the material evening sieving part; the feeding part comprises a rack I, a hopper, a vibrating motor I and a mixed object collector I; the material evening sieving part comprises a rack II, a vibrating bed, a vibratingmotor II and a mixed object collector II; the grading part comprises CCD cameras, a microprocessor, a sealed box, a light supplementing lamp and a cleaner; the air blowing part comprises air tube pillars, an electromagnetic valve and an air pump; the collecting part comprises a collecting box I, a collecting box II, a collecting box III, a collecting box IV and a collecting box V. With the graderfor coffee beans, the coffee raw beans can be graded according to particle diameters, baked coffee beans are graded according to colors, the efficiency of sorting the coffee beans is improved, and labor intensity is lowered.

Description

technical field [0001] The invention relates to a coffee bean grading machine and a grading method, belonging to the technical field of agricultural material screening equipment. Background technique [0002] The classifier is a non-destructive sorting equipment used for quality inspection and grading of bulk materials. It is widely used in grain, food, pigment chemical industry and other industries. It is difficult to sort recycled plastic sheets, plastic granules, corn, various Bean, ore, chili, garlic, melon seeds, raisins, seeds, traditional Chinese medicine, sea rice, shrimp skin, clove fish, and special materials are all very effective in sorting. [0003] At present, my country's coffee planting area and output have reached a very large scale, but there are many problems in the classification of coffee bean size and quality and subsequent processing. At present, the grading of the size and quality of green coffee beans mainly relies on manual grading. On the one hand...
