Description

Technical Field

[0001] This utility model relates to the technical field of beer fermentation equipment, and in particular to a beer yeast addition device. Background Technology

[0002] Brewer's yeast is a typical top-fermenting yeast commonly used in beer production. Physical properties: It is pale yellow in color, similar to the color of peeled peanuts, and has a fineness of 60-120 mesh (see flour). Currently, the methods for adding yeast to craft beer are: after the wort has boiled, it is circulated and cooled in the boiling kettle. Once the temperature is suitable, the yeast is added to the boiling kettle and then pumped into the fermentation tank. Alternatively, the yeast can be added directly to the fermentation tank after the wort has circulated and cooled and pumped in. Both of these methods require opening the fermentation tank or boiling kettle, which introduces excessive oxygen and can cause over-fermentation, negatively impacting the beer's taste.

[0003] In the prior art, there is a Chinese utility model patent with publication number CN219010242U entitled "Yeast Addition Mechanism for Fermentation Tanks," which connects a yeast addition tank to the discharge pipe of the cooling component, allowing yeast to be added directly during wort delivery, thus overcoming the aforementioned problems. However, due to the physical properties of beer yeast, a certain amount of wort or concentrate needs to be added to the addition tank to dissolve the yeast, or the yeast-containing fermentation liquid can be dissolved first and then poured into the addition tank. Both methods are cumbersome and introduce external solvents, potentially affecting beer production. Utility Model Content

[0004] The purpose of this invention is to provide a brewer's yeast addition device to solve the problems that existing methods of adding brewer's yeast are cumbersome and introduce external solvents, which may affect beer production.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A brewer's yeast addition device is provided, which connects a boiling kettle and a fermentation tank. The device includes a pump body, a plate cooler, a yeast addition tank, a main pipe, and a branch pipe. The liquid outlet of the boiling kettle is connected to the liquid inlet of the fermentation tank through the pump body, the low-temperature passage of the plate cooler, and the main pipe in sequence. The branch pipe is connected in parallel with the main pipe, and the yeast addition tank is installed on the branch pipe.

[0007] A further technical solution is: two first valves are installed on the branch pipe, and the two first valves are located at both ends of the yeast addition tank.

[0008] A further technical solution is that an antifoamer is provided at the liquid outlet end of the main pipe.

[0009] A further technical solution is that a second valve is provided at the liquid inlet end of the main pipe.

[0010] A further technical solution is that a thermometer is installed at the liquid inlet end of the main pipe.

[0011] A further technical solution is that flow meters are installed on both the main pipe and the branch pipe.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] This invention proposes a brewer's yeast addition device. The device connects a yeast addition tank to the conveying pipeline between the boiling kettle and the fermentation tank. Yeast can be directly added to the conveying wort without opening the boiling kettle and the fermentation tank, preventing the wort from introducing too much oxygen and causing over-fermentation. In addition, the wort itself can be directly introduced as a solvent when dissolving the yeast, which is convenient to operate and avoids the introduction of new solvents, thus ensuring product quality.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0022] This implementation example Figure 1 As shown, a beer yeast adding device is connected between a boiling kettle 1 and a fermentation tank 2. The device includes a pump body 3, a plate cooler 4, a yeast adding tank 5, a main pipe 6, and a branch pipe 7. The liquid outlet of the boiling kettle 1 is connected to the liquid inlet of the fermentation tank 2 through the pump body 3, the low temperature passage of the plate cooler 4, and the main pipe 6 in sequence. The branch pipe 7 is connected in parallel with the main pipe 6, and the yeast adding tank 5 is installed on the branch pipe 7.

[0023] The wort in the boiling kettle 1 is pumped by the pump body 3 (centrifugal pump) to the plate cooler 4 for cooling, and then enters the fermentation tank 2 through the main pipe 6. During this period, an appropriate amount of yeast powder is added to the yeast addition tank 5, and the branch pipe 7 of the yeast addition tank 5 is opened. At this time, the wort in the main pipe 6 will also enter the yeast addition tank 5 to dissolve the yeast powder as a solvent. As the amount of wort in the yeast addition tank 5 increases, a parallel passage will be formed for circulation, and the yeast powder will enter the fermentation tank 2 along with the wort. After one yeast addition is completed, the branch pipe 7 can be closed for the next use.

[0024] Preferably, two first valves 8 are provided on the branch pipe 7, and the two first valves 8 are located at both ends of the yeast addition tank 5 respectively.

[0025] The working process of this utility model is as follows: Looking along the wort flow direction, the first valve 8 acts as both the passage and the circuit breaker of the branch pipe 7. Its main functions are: first, to control the entire branch pipe 7; and second, to allow the wort to enter the yeast addition tank 5 to dissolve the yeast powder. The second valve 8 mainly prevents the wort in the yeast addition tank 5 from flowing out. When both valves 8 are closed simultaneously, the yeast addition tank 5 is isolated, facilitating cleaning and adding yeast powder.

[0026] Preferably, the liquid outlet end of the main pipe 6 is equipped with a defoamer 9.

[0027] The pump body 3 will generate some air bubbles when conveying wort. The defoamer 9 can eliminate the air bubbles to ensure the conveying and fermentation effects.

[0028] Preferably, the inlet end of the main pipe 6 is provided with a second valve 10.

[0029] The second valve 10 is used to control the flow rate of the main pipe 6.

[0030] Preferably, a thermometer 11 is provided at the liquid inlet end of the main pipe 6.

[0031] The thermometer 11 can detect the temperature of the wort after passing through the plate cooler 4, ensuring the appropriate temperature when the yeast is added to the wort, which in turn ensures the activity of the yeast.

[0032] Preferably, both the main pipe 6 and the branch pipe 7 are equipped with flow meters 12.

[0033] Two flow meters 12 can monitor the flow of the main pipe 6 and the branch pipe 7 respectively, so as to facilitate the control of cooling temperature and yeast addition rate.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
