Description

Technical Field

[0001] This utility model relates to the field of coffee fermentation technology, and in particular to a coffee fermentation device that automatically regulates oxygen content. Background Technology

[0002] The commonly used method for processing coffee beans is to ferment the peeled coffee beans after peeling, using pectinase secreted by microorganisms to break down pectin. After fermentation, the beans are washed with water to remove the oligosaccharides, thus avoiding the adverse effects of pectin on coffee quality.

[0003] The commonly used microbial strain for coffee bean fermentation is yeast. Yeast is a facultative anaerobic bacterium, which has high requirements for controlling the oxygen content in the fermentation broth. Current control methods are difficult to automate, often requiring manual sampling and activation of the oxygen supply device to adjust the oxygen content of the fermentation broth. This affects fermentation efficiency, increases workload, and because the detection of sampling results and the amount of oxygen supplied depend on operator experience, different operators have varying levels of skill, leading to significant differences in the taste of the coffee beans after fermentation and inconsistent product quality.

[0004] Traditional fermentation processes require manual operation, resulting in a long fermentation time.

[0005] Transporting and washing large quantities of fermented coffee beans requires a significant amount of manpower, resources, and time.

[0006] Traditional fermentation tanks require manual cleaning after fermentation, which increases the workload. Utility Model Content

The output of the first drive motor 201 drives the connecting rod 202 to rotate, the connecting rod 202 drives the extension arm 203 to rotate, the extension arm 203 drives the first fixed shaft 204 to rotate, the first fixed shaft 204 drives the fermentation sealing door 3 to rotate inward around the second fixed shaft 205 as the center, and finally closes, and makes the meshing part 110 inside the bucket lid mesh with the meshing end 510 under the action of external force, thereby making the stability of the stirring rotating shaft 502 better; clean water is introduced from the water inlet pipe 105, the second motor 501 is started, the output of the second motor 501 drives the stirring rotating shaft 502 to rotate, and the stirring component 5 set in this scheme automatically completes the cleaning of a large number of coffee beans in the bucket. When the operator needs to ferment the coffee beans, yeast is added, and multiple data are monitored through the central control panel 509 and the oxygen generator pump 508 and the gas one-way solenoid valve 107 are controlled and adjusted to make the oxygen content meet the user's needs;
