Description

Technical Field

[0001] This application relates to the field of fermentation technology, specifically to a coffee bean fermentation device. Background Art

[0002] The main purpose of coffee bean fermentation is to improve its taste and quality. Through fermentation, the bad flavors in coffee beans can be removed, the aroma and taste of coffee can be enhanced, making it more rich and mellow. In addition, fermentation can also improve the antioxidant property and stability of coffee beans and extend their shelf life.

[0003] The fermentation process of coffee beans is a biochemical reaction, and its principle is similar to that of other food fermentation processes. In a closed environment, by controlling conditions such as temperature, humidity, and oxygen content, the microorganisms in coffee beans (mainly lactic acid bacteria and yeast) are activated to decompose substances such as sugars and organic acids in coffee beans, producing unique aroma and flavor substances.

[0041] As Figure 1 shown, this application provides a coffee bean fermentation device, including a support frame 1 and a tank body 2 fixedly arranged at the upper end of the support frame 1. The tank body 2 is suitable for placing coffee beans and other materials;

[0042] A feeding port 3 is fixedly arranged at the upper end of the tank body 2. At the same time, a discharging port 4 is fixedly arranged at the lower end of the tank body 2. The feeding port 3 and the discharging port 4 are suitable for the input and output of coffee beans and other materials. And a ventilation pipe 5 is fixedly arranged on one side of the upper end of the tank body 2 away from the feeding port 3. At the same time, a pressure gauge 6 is fixedly arranged on the ventilation pipe 5. The pressure gauge 6 is suitable for detecting the air pressure value inside the tank body 2;

[0043] And a valve (not marked in the figure) is sleeved on the ventilation pipe 5. The valve is suitable for controlling the discharge of gas. When the pressure gauge 6 detects that the air pressure inside the tank body 2 is too high, the valve can be opened to discharge the gas through the ventilation pipe 5;

[0044] At the same time, a temperature control pipe 8 is sleeved outside the tank body 2. The temperature control pipe 8 is provided with an outlet and an inlet, which are suitable for introducing a cooling medium to timely remove the heat generated by biological oxidation and mechanical stirring, ensuring that the fermentation process is carried out under constant temperature conditions;

[0045] As Figures 1-4 shown, a fermentation mechanism 7 is fixedly arranged inside the tank body 2. The fermentation mechanism 7 is suitable for the fermentation treatment of coffee beans. The fermentation mechanism 7 includes a support column 72 fixedly arranged inside the tank body 2. At the same time, a baffle 71 is fixedly arranged inside the tank body 2. The baffle 71 is arranged in a circle inside the tank body 2 and is fixedly connected to the inside of the tank body 2 by the support column 72;

[0046] At the same time, a stirring assembly 73 is arranged inside the baffle 71. The stirring assembly 73 includes a driving unit fixedly arranged at the upper end of the tank body 2. The driving unit includes a support platform (not marked in the figure) fixedly arranged at the middle position of the upper end of the tank body 2. A motor 730 is fixedly arranged at the lower end of the support platform. The output end of the motor 730 penetrates the tank body 2 and is fixedly provided with a stirring shaft 735. At the same time, a shaft seal 731 is fixedly arranged at the connection between the output end of the motor 730 and the tank body 2. The shaft seal 731 is suitable for preventing leakage and contamination of miscellaneous bacteria;

[0047] Meanwhile, a stirring paddle 734 is fixedly sleeved at the lower end of the stirring shaft 735. The impellers on the stirring paddle 734 are arranged in a flat blade pattern. The stirring paddle 734 is suitable for keeping the coffee beans in the liquid in a suspended state for fermentation. And a bubble-breaking paddle 733 is fixedly sleeved on the stirring shaft 735 away from the stirring paddle 734. The impellers on the bubble-breaking paddle 733 are arranged in a curved blade pattern. The bubble-breaking paddle 733 is suitable for breaking the bubbles that appear during stirring;

[0048] Meanwhile, an anti-foaming device 732 is fixedly sleeved at the upper end of the stirring shaft 735. The anti-foaming device 732 is suitable for processing the bubbles broken by the bubble-breaking paddle 733 and then reflowing them back into the original liquid. The anti-foaming device 732 includes two groups of fixing plates 738 fixedly arranged on the stirring shaft 735. A plurality of groups of impellers (not marked in the figure) are fixedly arranged between the fixing plates 738. Meanwhile, the impellers are arranged in a circular pattern between the two groups of fixing plates 738 to form an anti-foaming chamber 736. The anti-foaming chamber 736 is a region where the bubbles are broken by the turbine blades and become liquid. Meanwhile, an anti-foaming channel 737 is fixedly arranged at the lower end of the anti-foaming chamber 736. The anti-foaming channel 737 is suitable for bringing the bubbles into the anti-foaming chamber 736;

[0049] It should be noted that after the bubbles are processed in the anti-foaming chamber 736, they will reflow back into the original liquid along with the rotation of the anti-foaming device 732;

[0050] When the coffee beans and the liquid enter the fermentation tank for fermentation, the stirring assembly 73 in the fermentation mechanism 7 will stir them to make them fully blend and ferment. When the driving unit in the stirring assembly 73 drives the stirring shaft 735 to drive the stirring paddle 734 to stir, bubbles will appear and affect the fermentation. At this time, the bubble-breaking paddle 733 on the stirring shaft 735 will break the bubbles, and then the anti-foaming device 732 will process the bubbles and reflow them back into the original liquid;

[0051] As Figure 2 and Figure 5 shown, a flushing assembly 74 is fixedly arranged at the upper end inside the tank body 2. The flushing assembly 74 is suitable for flushing the liquid adhering to the inner wall of the tank body 2 and reflowing it back into the original liquid;

[0052] The flushing assembly 74 includes an air inlet 740 fixedly arranged at the upper end of the tank body 2. The air inlet 740 is suitable for injecting gas. Meanwhile, the air inlet 740 penetrates through the tank body 2 and a trachea 742 is fixedly arranged. The trachea 742 is arranged along the inner wall of the tank body 2 in a circular pattern. Meanwhile, a plurality of groups of connecting frames 741 are sleeved on the trachea 742. Meanwhile, the connecting frames 741 are fixedly connected to the inside of the tank body 2 and are suitable for fixing the trachea 742;

[0053] Meanwhile, a plurality of groups of nozzles 743 are arranged on the trachea 742. The nozzles 743 are suitable for flushing the residual liquid on the inner wall to make it reflow back into the original liquid;

[0054] It should be noted that since an anaerobic environment needs to be constructed inside the fermenter to facilitate anaerobic fermentation, the gas injected can be carbon dioxide to maintain the gas concentration inside the tank body 2.

[0055] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
