Description

Technical Field

[0001] The utility model relates to the technical field of coffee bean processing equipment, in particular to a coffee bean peeling and degumming machine. Background Art

[0002] As an important beverage in the world, coffee plays a pivotal role in people's daily life. At present, coffee planting and distribution are mainly concentrated in tropical and subtropical regions. Coffee planting in my country is mainly distributed in Hainan, Yunnan and other regions. Coffee degumming methods include natural fermentation degumming, chemical degumming, biological degumming, and physical degumming. The physical degumming method is to peel the fresh coffee fruit and then wash it, and constantly rub the coffee beans during the washing process to remove the mucus. This method usually uses a water washing machine to achieve the purpose of degumming.

[0003] The existing coffee bean degumming machine will remove the outer skin of the coffee beans before degumming the coffee beans to prevent the outer skin from hindering the degumming step, and send the peeled coffee beans into the degumming mechanism for degumming. For example, Chinese patent publication No. CN103750513B discloses "a coffee raw and ripe fruit separation, peeling and degumming combined machine", which puts raw and ripe mixed coffee fruits into a raw and ripe fruit separation device to squeeze the coffee beans against each other. Since the flesh of the ripe fruit is much softer than that of the raw fruit, the ripe fruit flesh is crushed during the squeezing of the ripe fruit with the raw fruit, exposing the coffee beans inside. The crushed flesh and coffee beans fall into the collector through the mesh screen and enter the peel separation device. The fruit in the raw and ripe fruit separation device is pushed to the fruit discharge outlet by the rotating shaft. When the fruit accumulates to a certain amount, the pressure door is forced to open, and the fruit is discharged from the fruit discharge outlet; a gravity block is installed on the pressure door to compress more fruit and improve the squeezing efficiency;

[0004] However, in actual use, since the peels, pulp and coffee beans are mixed and input into the degumming device, the peels themselves are relatively tough, resulting in the degumming device being blocked by the peels and unable to operate normally. Frequent cleaning is required, which increases the cost of use and affects processing efficiency. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes a coffee bean peeling and degumming machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A coffee bean peeling and degumming machine is designed, comprising a degumming device, wherein the degumming device comprises a machine case, a peeling mechanism and a degumming mechanism, and a collecting trough for placing a collecting box is arranged below the machine case to cooperate with the peeling mechanism and the degumming mechanism;

[0008] The upper end of the chassis is fixedly provided with a discharge port, and a feeding structure matched with the discharge port and the degumming mechanism is fixedly provided inside the chassis, and the lower end and both sides of the feeding structure are provided with strip grooves for screening peels;

[0009] A cleaning component matched with the feeding structure is arranged in the chassis.

[0010] Furthermore, the cleaning component includes a U-shaped frame arranged outside the feeding structure, and the inner wall of the U-shaped frame is fixedly provided with bristles that match the feeding structure.

[0011] Furthermore, two pulleys are rotatably arranged in the chassis, the two pulleys are connected by belt power, and the belt is fastened to the U-shaped frame by a plurality of bolts.

[0012] Furthermore, a servo motor is fixedly arranged in the chassis, a synchronous pulley is fixedly arranged on the output shaft of the servo motor and one of the pulleys, and the two synchronous pulleys are connected by a synchronous belt force.

[0013] Furthermore, two guide rails are fixedly arranged in the chassis, and guide grooves matching with the guide rails are provided on both sides of the U-shaped frame.

[0014] Furthermore, a water pipe is connected to the side of the feeding structure away from the degumming mechanism, and a PLC control device electrically connected to the peeling mechanism and the degumming mechanism is provided on the chassis.

[0015] The utility model provides a coffee bean peeling and degumming machine, which has the following beneficial effects:

[0016] In the utility model, the coffee fruit is peeled and degummed by a peeling mechanism and a degumming mechanism, and the peel and part of the pulp are filtered out by opening a strip groove on the feeding structure, thereby reducing the burden of the degumming mechanism and reducing the frequency of cleaning thereof;

[0017] Secondly, in the utility model, a cleaning component is provided to clean the feeding structure to prevent the bar grooves on the feeding structure from being clogged with pulp and unable to filter, and a water pipe is connected to the side of the feeding structure away from the degumming mechanism. When cleaning the feeding structure, water can be supplied to flush away the cleaned pulp to avoid clogging the bar grooves again. BRIEF DESCRIPTION OF THE DRAWINGS
