Description

Technical Field

[0001] The utility model relates to the technical field of coffee fermentation, in particular to a coffee fermentation device which is convenient for increasing oxygen. Background Art

[0002] Coffee is a common beverage. Currently, during the coffee processing process, coffee can be fermented, among which wet fermentation is a commonly used fermentation method. Wet fermentation is to immerse the cleaned coffee in a water tank for fermentation. After fermentation, the pectin of the coffee beans falls off naturally, and at the same time, lactic acid bacteria decompose the sugar in the coffee pectin.

[0003] The application number in the existing public technology is: CN201921520334.6. A coffee fermentation device that utilizes microbial fermentation is provided. By setting an air pump and an air pipe, when the coffee enters the water and begins to ferment, sufficient oxygen is introduced into the water, so that the fermenting microorganisms can smoothly complete the fermentation process without performing anaerobic respiration due to lack of oxygen, thereby producing products such as lactic acid or alcohol, causing the quality of the coffee to deteriorate or the products of anaerobic respiration to damage the coffee and make it unusable, causing huge losses.

[0004] However, the above patent still has certain disadvantages when used: although it can conveniently deliver oxygen to the water body for fermenting coffee through the provided air pump and air pipe, when the air pipe is directly connected to the water body, after the oxygen enters the water body, it overflows from the top of the water body before it is absorbed into the water body, making it difficult to quickly increase the oxygen content of the water body. Moreover, the position of the air supply pipe is relatively fixed, so that the sprayed oxygen cannot act evenly on the coffee at different positions, thereby affecting the subsequent fermentation quality of the coffee. In addition, the oxygen retains for a short time inside the device, which further limits the effect of oxygen absorption into the water, making the overall oxygenation effect less than ideal and reducing the practicality of the device.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] (1) Technical problems solved

[0007] In view of the shortcomings of the existing technology, the present invention provides a coffee fermentation device that is easy to oxygenate, which has the advantages of comprehensive oxygenation, good oxygenation effect, and leakage blocking, thereby solving the problems in the above-mentioned background technology.

[0008] (2) Technical solution

[0009] In order to achieve the above advantages of comprehensive oxygenation, good oxygenation effect and leakage blocking, the specific technical solutions adopted by the utility model are as follows:

[0010] A coffee fermentation device that is convenient for oxygenation comprises a fermentation tank and a base, wherein a plurality of groups of oxygenation pipes are installed around the inner surface of the fermentation tank, a plurality of groups of exhaust holes are provided on the surface of the oxygenation pipes, one end of the oxygenation pipes passes through one side of the fermentation tank and is connected to a diverter plate, an oxygen supply pipe is installed on one side of the top of the diverter plate, a drive shaft is provided between the oxygenation pipes at a middle position inside the fermentation tank, a plurality of groups of mounting cylinders are fixedly installed on the surface of the drive shaft, a plurality of groups of stirring blades are installed around the surface of the mounting cylinders, a plurality of groups of blocking grooves are evenly provided on the surfaces of both ends of the stirring blades, and the stirring blades are located between the oxygenation pipes.

[0011] Furthermore, one end of the driving shaft passes through one side of the fermentation tank and is connected to the motor.

[0012] Furthermore, a feed port and a pressure relief valve are respectively installed on both sides of the top of the fermentation tank.

[0013] Furthermore, a discharge pipe and a liquid discharge pipe are respectively installed at the bottom of both sides of the fermentation tank.

[0014] Furthermore, a filter is installed on one side of the drainage pipe at the bottom end of the inner surface of the fermentation tank.

[0015] Furthermore, a scraper is installed at the bottom of the driving shaft.

[0016] Furthermore, a base is installed at the bottom of the fermentation tank.

[0017] Furthermore, the oxygen supply pipe is connected to an external oxygen enrichment device.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the present invention provides a coffee fermentation device that facilitates oxygenation and has the following beneficial effects:

[0020] The utility model adopts an oxygenation tube and a blocking groove. When oxygenation is needed, oxygen can be introduced through the oxygenation tube. Since the oxygenation tube is widely distributed and the exhaust holes on the surface are small and dense, the oxygen can be directly introduced into different positions inside the fermentation tank at one time. At the same time, the introduced oxygen enters the water in the form of fine bubbles. At this time, the fine bubbles will quickly burst and then melt into the water, thereby increasing the oxygen content of the water and thus improving the subsequent fermentation effect. Moreover, when the oxygen floats up, the high-speed rotating stirring blades inside increase the contact area with the oxygen, so that the oxygen is restricted by the blocking groove on the surface, delaying the floating progress, thereby extending the retention time of the oxygen, allowing the oxygen to be more fully melted into the water, thereby improving the overall oxygenation efficiency, and having the advantages of comprehensive oxygenation, good oxygenation effect, and leakage blocking.

The feed port 2 is provided to facilitate the addition of coffee beans, water and other substances used for fermentation, so as to facilitate subsequent fermentation operations, while the pressure relief valve 5 is provided to discharge the gas to a certain extent to avoid the occurrence of danger caused by excessive internal pressure.

[0033] In one embodiment, a discharge pipe 12 and a liquid discharge pipe 16 are respectively installed at the bottom of both sides of the fermentation tank 1.
