Description

Technical Field

[0001] The utility model relates to the technical field of beer production equipment, in particular to an oxygenating device for a beer fermentation tank. Background Art

[0002] In the process of beer production, brewer's yeast is needed. It is a facultative anaerobic microorganism that grows and reproduces under aerobic conditions and undergoes alcohol fermentation under anaerobic conditions. Beer fermentation requires a large amount of yeast. In order to save costs, it is necessary to introduce an appropriate amount of oxygen into the wort before the beer ferments, so that the yeast can reproduce under aerobic conditions to achieve the yeast required for the fermentation process, and then fermentation can be carried out. When introducing oxygen into the beer fermentation tank, an oxygenating device is required.

[0003] After searching, it was found that the utility model patent with the authorization announcement number CN208279590U disclosed an oxygenation device for a beer fermentation tank and the utility model patent with the authorization announcement number CN205893209U disclosed an oxygenation device for small and medium-sized beer fermentation tanks. After analysis, it was found that both of them have a common problem: more wort may flow into the oxygen pipe. It can be seen from a beer fermentation tank oxygenation device (such as Figure 1 ), the flow directions of oxygen and wort in the three-way pipe 11 are opposite. If the pressure of the wort is greater than the pressure of the oxygen, the wort may flow into the oxygen pipe. This situation often occurs when the oxygen tank is insufficient in oxygen. An oxygenating device for small and medium-sized beer fermenters is directly connected to the beer tank sewage butterfly valve. In this case, the required oxygen pressure is greater. Therefore, the above two have higher requirements for oxygen pressure when in use. If the oxygen pressure is low, there is a possibility that more wort will flow into the oxygen pipe.

[0004] Therefore, it is necessary to provide a beer fermentation tank oxygenation device to solve the above technical problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an oxygenation device for a beer fermenter, which can prevent more wort from entering the oxygen pipe when the oxygen pressure of the air inlet pipe is low and blocked.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The oxygenation device of a beer fermentation tank comprises: a three-way pipe, wherein the three-way pipe is connected to an oxygen pipe, and oxygen in an oxygen cylinder enters into the three-way pipe through the oxygen pipe, and two sides of the three-way pipe are respectively connected to a first connecting pipe and a second connecting pipe, and an air intake pipe is arranged on the three-way pipe, and an annular groove is provided on the inner wall of the air intake pipe, and an annular inclined groove connected to the annular groove is provided on the top of the annular groove, and a plug is movably provided inside the annular groove, and the plug is a truncated cone structure, which is adapted to the annular inclined groove, and a plurality of arc grooves are provided on the lower part of the inner wall of the air intake pipe, and the plurality of arc grooves are all connected to the annular groove.

[0011] Preferably, an unpowered impeller assembly is also provided in the three-way pipe.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] (1) When the oxygen pressure of the air inlet pipe of the utility model is low, the plugging can prevent more wort from entering the oxygen pipe. When the oxygen pressure is high, the plugging moves downward under the push of oxygen, so that oxygen enters the three-way pipe and mixes with the wort.

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0024] like Figure 2-6As shown, the oxygenation device for a beer fermentation tank provided by the utility model comprises: a three-way pipe 1, the three-way pipe 1 is connected to an oxygen pipe, oxygen in an oxygen bottle enters into the three-way pipe 1 through the oxygen pipe, two sides of the three-way pipe 1 are respectively connected to a first connecting pipe 2 and a second connecting pipe 3, the first connecting pipe 2 is connected to a plate heat exchanger, and the second connecting pipe 3 is connected to a beer fermentation tank. Before the wort enters the beer fermentation tank, it needs to be cooled by the plate heat exchanger. Generally, the wort is cooled to 20°C before being passed into the first connecting pipe 2. After that, the wort enters the three-way pipe 1 again, and finally flows into the beer fermentation tank through the second connecting pipe 3. When the wort flows into the three-way pipe 1, the wort is mixed with oxygen, so that the wort contains an appropriate amount of oxygen, thereby causing the yeast therein to multiply and increase the number of yeasts. An air inlet pipe 4 is arranged on the three-way pipe 1, and an annular groove 41 is arranged on the inner wall of the air inlet pipe 4. An annular inclined groove 42 connected to the annular groove 41 is arranged on the top of the annular groove 41, and a plug 43 is movably arranged inside the annular groove 41, and the plug 43 is a circular The trapezoidal structure is adapted to the annular bevel groove 42, and can seal the annular bevel groove 42. A plurality of arc grooves 44 are provided at the lower part of the inner wall of the intake pipe 4, and the plurality of arc grooves 44 are connected to the annular groove 41. When the tee pipe 1 is installed, it is necessary to ensure that the intake pipe 4 is upward, so that the plug 43 can be dropped to the bottom of the annular groove 41 by gravity. At the same time, high-pressure oxygen is filled into the intake pipe 4, and the oxygen can enter the plurality of arc grooves 44 through the annular bevel groove 42 and the annular groove 41, and finally the oxygen passes through A plurality of arc grooves 44 enter into the three-way pipe 1. When the oxygen pressure drops to a certain value, part of the wort enters into the air inlet pipe 4 and pushes the plug 43 to move upward until the plug 43 is completely in contact with the annular inclined groove 42. At this time, the wort cannot enter above the plug 43. In this embodiment, when the oxygen pressure is low, the plug 43 can prevent more wort from entering the oxygen pipe when the oxygen pressure is low. When the oxygen pressure is high, the plug 43 moves downward under the action of oxygen, so that oxygen enters the three-way pipe 1 and mixes with the wort.

[0025] Example 2

[0026] The plug 43 is made of rubber. After the wort contacts it, the wort will push it upward and provide buoyancy, so that the plug 43 can move upward more easily, so as to achieve the purpose of closing the annular chute 42 .

[0027] Example 3

[0028] like Figure 3 As shown, a flow pipe 5 is fixed inside the three-way pipe 1, and the wort flowing out of the plate heat exchanger passes through the flow pipe 5. The air intake pipe 4 is connected to the flow pipe 5, and oxygen enters the flow pipe 5 through the air intake pipe 4. Therefore, the wort and oxygen are preliminarily mixed in the flow pipe 5.

[0029] Furthermore, the circulation pipe 5 is composed of three parts, namely a long tapered tube 51, an intermediate thin tube 52 and a short tapered tube 53. The long tapered tube 51 and the short tapered tube 53 are respectively located on both sides of the intermediate thin tube 52. The flowing wort first enters the long tapered tube 51. When the tapered tube 51 contracts and subsequent wort continues to enter, the speed of the wort is increased, and it enters the intermediate thin tube 52 at a higher speed. The high-speed wort collides with the oxygen delivered by the air intake pipe 4, so that the two are quickly and evenly mixed. The mixed wort flows into the short tapered tube 53, and is affected by the expansion of the short tapered tube 53, and its speed is quickly reduced, thereby further improving the effect of uniform mixing of oxygen and wort.

[0030] Example 4

[0031] like Figure 3 As shown, an unpowered impeller group 6 is also arranged in the three-way pipe 1. The flowing wort drives the impeller group 6 to rotate, and the rotating impeller group 6 further improves the effect of uniform mixing of oxygen and wort.

[0032] Working principle:

[0033] When in use, the first connecting pipe 2 is connected to the plate heat exchanger, the second connecting pipe 3 is connected to the fermentation tank, and then the valves are closed to allow the wort and high-pressure oxygen to enter the three-way pipe 1. The oxygen in the air intake pipe 4 passes through the annular chute 42, the annular groove 41 and the arc groove 44 to enter the middle capillary 52. ​​The wort cooled by the plate heat exchanger passes through the first connecting pipe 2 and the long tapered pipe 51 to enter the middle capillary 52. ​​At this time, the oxygen and wort are quickly mixed in the middle capillary 52. ​​When the oxygen pressure drops to a certain value, that is, the oxygen pressure is less than the wort pressure inside the middle capillary 52, part of the wort enters the air intake pipe 4 and lifts up the blockage 43 until the blockage 43 is completely in contact with the annular chute 42. The wort cannot enter above the blockage 43, thereby preventing more wort from entering the oxygen pipe.

[0034] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
