Description

Technical Field

[0001] The utility model relates to the technical field of coffee bean processing, in particular to a fermentation device for coffee bean processing. Background Art

[0002] Coffee bean fermentation is a biochemical process that occurs in coffee beans under specific environmental conditions, after the cherries are picked and the pulp and skin are removed. The primary purpose of fermentation is to remove the sticky pectin on the surface of the coffee beans and develop the coffee's unique flavor.

[0003] For example, a novel coffee bean fermentation device disclosed in Patent Publication No. CN211268472U comprises an outer shell, an inner shell, a stirring device, and a top cover. The outer shell is a cylindrical device with upper and lower openings, while the inner shell is open at the top and has a lower end that slopes gradually toward the center. By adopting this technical solution, the device facilitates separation of the fermentation liquid from the coffee beans, making bean removal easy, and the stirring shaft ensures that the slippery paste is fully separated from the inner rind.

[0004] Although the above patent facilitates the separation of fermentation liquid from coffee beans, the upper end area of ​​the discharge separator is small. During the separation process, coffee beans and fermentation liquid are easily accumulated on the discharge separator, resulting in blockage and making the separation process lengthy. Utility Model Content

[0005] The purpose of the present invention is to provide a fermentation device for processing coffee beans to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A fermentation device for coffee bean processing, comprising

[0008] A fermentation box, wherein an inner frame is movably installed in the middle of the inner side of the fermentation box, a filter plate with holes is fixedly installed below the inner frame, and a stirring mechanism is provided in the middle of the inner frame of the fermentation box;

[0009] The fermentation box is provided with a separation mechanism below the perforated filter plate, and the fermentation box is provided with a feeding mechanism on the upper end of one side close to the inner frame.

[0010] Preferably, the stirring mechanism includes a motor 1, which is fixedly installed at the middle of the top of the fermentation box, and the output shaft of the motor 1 is fixedly connected to the stirrer, and a feeding port is provided at the upper right end of the fermentation box;

[0011] Preferably, the separation mechanism includes a sealing ring, which is annularly arranged at the outer ring below the bottom end of the fermentation box near the perforated filter plate, and an electric push rod is fixedly installed on the outer side of the middle part of the bottom end of the fermentation box, and the output shaft of the electric push rod is fixedly connected to the blocking disk;

[0012] Preferably, the separation mechanism further comprises a blocking column, which is arranged at the lower right side of the fermentation box, and a through groove is formed through the bottom end of the blocking column, and a drainage port connected to the through groove is provided at the lower right side of the fermentation box;

[0013] Preferably, the unloading mechanism includes a gear ring, which is arranged at the outer ring of the upper end of the inner frame. A second motor is fixedly installed on the left side of the top end of the fermentation box. The output shaft of the second motor is fixedly connected to a gear, and the gear is meshed with the gear ring.

[0014] Preferably, the discharge mechanism further comprises a discharge pipe, which is symmetrically arranged on a side of the fermentation box away from the blocking column, and a discharge port is arranged on one side of the bottom end of the perforated filter plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This fermentation device for coffee bean processing is used in conjunction with an electric push rod, a perforated filter plate, a blocking plate and a blocking column. When the coffee beans are fermented, the electric push rod is started to control the blocking plate to descend. Since the discharge pipe, the blocking column and the blocking plate are movably connected, the fermentation liquid leaks after the blocking plate descends straight down, and the coffee beans are retained by the perforated filter plate. The fermentation liquid enters the blocking column from the groove and is discharged through the drain port, thereby facilitating solid-liquid separation without causing blockage.

[0017] 2. This fermentation device for processing coffee beans is used in conjunction with motor 2, gears, gear rings, a discharge port, a discharge pipe and a blocking column. After the coffee beans are separated from the fermentation liquid, motor 2 is started, and motor 2 drives the gear to rotate, and the gear drives the gear ring to rotate, and the gear ring drives the inner frame and the perforated filter plate to rotate until the discharge port moves from one end of the blocking column to one end of the discharge pipe. In this way, the coffee beans enter the discharge pipe from the discharge port and are discharged, thereby achieving the purpose of facilitating and quickly discharging.

The hopper 1 has two hoppers connected to the top of the hopper 1.

[0027] In this embodiment, when the coffee beans are fermented, the electric push rod 8 is started, and the electric push rod 8 controls the blocking plate 9 to descend. Since the discharge pipe 16, the blocking column 10 and the blocking plate 9 are movably connected, the fermentation liquid leaks after the blocking plate 9 descends linearly, and the coffee beans are intercepted by the perforated filter plate 3. The fermentation liquid enters the blocking column 10 from the through groove 11 and is then discharged through the drain port 12, thereby facilitating solid-liquid separation without causing blockage.

[0028] like Figure 3 and Figure 4 As shown, a feeding mechanism is provided at the upper end of the fermentation box 1 near the inner frame 2, and the feeding mechanism includes a gear ring 13, which is provided at the outer ring of the upper end of the inner frame 2.

In this way, the coffee beans enter the discharge pipe 16 from the discharge port 17 and are discharged, thereby achieving the purpose of facilitating and quickly discharging.

[0030] Working principle: When fermenting coffee beans, the coffee bean raw materials and the fermentation liquid are poured into the fermentation box 1 from the feeding port 6, and the motor 1 4 is started. The motor 1 4 drives the agitator 5 to stir the coffee beans and the fermentation liquid between the inner frame 2 and the perforated filter plate 3, so that the coffee beans are fully fermented; when the coffee beans are fermented, the electric push rod 8 is started, and the electric push rod 8 controls the blocking plate 9 to descend. Since the discharge pipe 16, the blocking column 10 and the blocking plate 9 are movably connected, the fermentation liquid leaks after the blocking plate 9 descends straightly, and the coffee beans are intercepted by the perforated filter plate 3. The fermentation liquid enters the blocking column 10 from the through groove 11 and is then discharged through the drain port 12; when the coffee beans are separated from the fermentation liquid, the motor 2 14 is started, and the motor 2 14 drives the gear 15 to rotate, the gear 15 drives the ring gear 13 to rotate, and the ring gear 13 drives the inner frame 2 and the perforated filter plate 3 to rotate until the discharge port 17 moves from one end of the blocking column 10 to one end of the discharge pipe 16, so that the coffee beans enter the discharge pipe 16 from the discharge port 17 and are discharged.
