Description

A coffee bean peeling and rinsing device

technical field

The invention relates to a coffee bean peeling and rinsing device, which belongs to the technical field of agricultural product processing equipment.

Background technique

Daily drinking coffee is made with coffee beans and various cooking utensils, and coffee beans are the nuts in the fruit of the coffee tree. After the coffee beans are obtained, they are roasted by proper roasting methods. After the mature coffee cherries are picked manually or mechanically, if the peel of the coffee beans cannot be removed in time, the quality of the coffee beans will be affected when the peel rots, causing the peculiar smell of the coffee beans. Therefore, the peel of the coffee cherries needs to be removed in time. Remove, then degumming and drying the coffee beans and put them in the warehouse for storage. At present, the commonly used method is to manually remove the coffee bean peel or mechanically remove the coffee bean peel. When mechanically removing the coffee bean peel, crush or scrape with pressure The outer peel of the coffee cherry is crushed by the method, and then the coffee beans and the peel are washed repeatedly with clean water to separate the crushed peel from the coffee beans. During the washing process, the coffee pectin attached to the surface of the coffee beans is removed by the way. , and finally finish drying and storage.

Due to the high energy consumption of the existing mechanical equipment, the silver skin of the coffee beans will be damaged when the coffee beans are obtained by extrusion or scraping, which will destroy the quality of the product and is not convenient for large-scale production. In use, a large amount of clean water is required when rinsing and flushing coffee beans, resulting in too much industrial wastewater. At the same time, the coffee pulp contains a lot of water, which is not convenient for subsequent processing.

Working process of the present invention is:

Ripe coffee fruit enters the peel separation device 2 through the feeder 17. Under the action of the height fine-tuning mechanism, the rotating shaft 6 of the peel separation device 2 has a slight angle with the horizontal direction, and the screen 7 and the peel separation device 2 The gap between the inner walls of the box increases sequentially from left to right, the motor 21 drives the rotating shaft 6 to rotate through the belt, and the coffee beans move from left to right under the action of the auger I9 of the peel separation device 2. The water outlet of the cleaning water circulation device 4 connected to the peel separation device 2 is opened, and the water flows into the peel separation device 2, and the coffee beans are separated from the coffee pulp under the extrusion of the peel squeezer 10 of the peel separation device 2, And then enter the middle of the peel separation device screen 7 or a part of the material enters the pulp separator 11 from the material inlet 23, and the pulp separator 11 rotates under the drive of the rotating shaft 6, so that the coffee beans rotate together, making it subject to collision force and centrifugal force. The coffee bean fruit collided by the pulp separator 11 is further broken, and the mixture is removed from the small hole 26 and the material outlet 25 of the pulp separator 11, and the coffee bean fruit colliding with the screen 7 under the centrifugal force is also further realized. Separation of beans from coffee rind. Due to the difference in quality between the separated coffee beans and the coffee peel, under the action of water flow and centrifugal force, the coffee peel will be thrown to the inner surface of the screen 7, and the surface of the screen 7 has small holes evenly distributed in the axial and radial directions Smaller than the shape and characteristic dimensions of coffee beans, it is ensured that the coffee peels can be discharged under the centrifugal force and water washing, and at the same time, the coffee beans are not sifted out, and are discharged by the peel and pulp collector 18 at the lower end of the peel separation device 2 under the impact of water flow Collect; at the same time, under the impact of the centrifugal force and the internal water flow of the screen 7, a part of the peel will be attached to the coffee peel baffle 8 for collection, and the peel attached to the coffee peel baffle 8 is also separated by the peel separation device under the impact of the water flow. 2. The peel and pulp collector 18 at the lower end is discharged and collected;

Because the quality of the coffee beans is much larger than that of the peel, they will sink at the bottom of the screen 7. Under the influence of the installation angle of the screen 7, the coffee beans will gradually move from left to right. The coffee bean baffle 12 is piled up. The coffee bean baffle 12 of the peel separation device has the function of collecting coffee beans and preventing the coffee beans from flying randomly on the screen 7. When the coffee beans accumulate to a certain amount, the coffee beans in the peel separation device The coffee beans at the baffle plate 12 will be discharged from the outlet of the screen cloth 7 and enter the degumming and rinsing device 3 through the feeding channel 19 .
