Description

Technical Field

[0001] The present invention relates to the technical field of beer cooling fermentation, and specifically, to a fresh beer cooling fermentation process. Background Art

[0002] Beer is a nutritious beverage. In addition to containing minerals, alcohol, and carbon dioxide, it also contains various vitamins, minerals, and amino acids required by the human body. Beer is a fermented wine with a low alcohol content containing carbon dioxide bubbles, which is mainly made from malt and fermented with hops. It is a refreshing beverage for preventing heatstroke, quenching thirst, and stopping sweating in summer and autumn. According to the research of medical and beverage experts, beer contains 4% alcohol, which can promote blood circulation. For example, a Chinese patent with the publication number CN113583769B, a beer fermentation process and fermentation equipment;

[0003] In the process of beer production, first, the malt is crushed and mixed with water, and a saccharification reaction is carried out at a specific temperature to decompose the starch in the malt into fermentable sugars and other nutrients under the action of enzymes, forming a saccharification mash. After saccharification is completed, clarified wort is obtained by filtration. Then, the wort is boiled in a boiling pot and hops are added to give the beer bitterness and aroma, and at the same time, it plays a role in sterilization and stabilizing foam. The boiled wort needs to be quickly cooled to a temperature range suitable for yeast fermentation. Generally, equipment such as a plate heat exchanger is used to exchange heat between cold water or other refrigerants and the wort to quickly reduce the wort temperature to about 5 - 8°C. Then, the cooled wort is pumped into a fermentation tank, and an appropriate amount of yeast strain is added at the same time. The yeast starts to ferment under suitable temperature, nutrient and other conditions. In the initial stage of fresh beer fermentation, once the yeast starts to reproduce and ferment, heat will be released. If this is not controlled, the fermentation temperature will rise sharply. Usually, a jacketed fermentation tank is selected to hold the cooled wort. A refrigerant can be introduced into the jacket of the tank body of this type of fermentation tank, such as an ethylene glycol aqueous solution, for the purpose of timely removing the heat generated by yeast fermentation to achieve the preliminary control of the fermentation temperature.

[0004] However, in the beer brewing industry, the fermentation tank usually has a relatively large volume. The refrigerant is only in the jacket of the tank wall, and heat transfer can only be achieved by the contact between the jacket and the wort. For the wort that is far from the jacket and does not contact the tank wall, it is difficult to cool down quickly and sufficiently. In this way, the temperature of some wort deep in the fermentation tank may be too high for a long time, affecting the stability of fermentation. Summary of the Invention

[0014] A connecting groove is formed on the contact surface between the spiral rack and the fermentation tank, and the connecting groove is fixedly communicated with the empty groove;

[0015] A water inlet is fixedly communicated with the end of the spiral rack, and a water outlet is fixedly communicated with the end of the spiral rack away from the water inlet.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0039] Please refer to Figures 1-8 As shown, this embodiment provides a fresh beer cooling fermentation process, which includes a support main body 100. A support tank 120 is fixedly connected to the top of the support main body 100. A feed inlet 121 is fixedly communicated with the surface of the support tank 120. A ladder 130 is fixedly connected to the top of the support main body 100. A stirring device 110 is fixedly connected to the inner cavity of the support main body 100. A cooling component 200 for carrying wort is arranged in the inner cavity of the support tank 120;

[0040] A channel for circulating the refrigerant is arranged in the inner cavity of the cooling component 200, and the refrigerant flows in this channel, so as to cool the wort in contact with the cooling component 200;

[0041] The inner cavity of the cooling component 200 is provided with an auxiliary cooling component 300. The auxiliary cooling component 300 is used to cool the wort in the inner cavity of the cooling component 200, and the refrigerant flowing in the inner cavity of the cooling component 200 is in communication with the auxiliary cooling component 300. A driving component 400 is arranged at the end of the cooling component 200;

[0042] During beer production, malt is first crushed and mixed with water, and undergoes a saccharification reaction at a specific temperature. Under the action of enzymes, malt starch is converted into fermentable sugars, etc., to obtain a saccharified mash. After filtration, clarified wort is obtained. The wort is boiled in a boiling pot with hops added to impart flavor to the beer and sterilize and stabilize the foam. Then, with equipment such as a plate heat exchanger, cold water or refrigerant is used for heat exchange with the wort to quickly reduce the wort temperature from the boiling temperature to 5 - 8 °C. Finally, it is pumped into the cooling component 200 for fermentation.

[0043] After pouring the cooled wort into the inner cavity of the cooling component 200, an appropriate amount of yeast strain is added, and the stirring device 110 is started to rotate in the inner cavity of the cooling component 200 to fully mix the yeast strain and the wort evenly. After stopping the stirring, the wort starts to ferment. Considering that in the initial stage of fresh beer fermentation, once the yeast starts to reproduce and ferment, heat will be released. If this is not controlled, the fermentation temperature will rise sharply. At this time, the driving component 400 will work to drive the refrigerant to flow in the inner cavity of the cooling component 200, thereby cooling the wort in contact with the inner wall of the cooling component 200;

[0044] At the same time, considering that in the beer brewing industry, the cooling component 200 carrying the wort is generally large in volume. Relying only on the flowing refrigerant to take away the heat of the wort takes a long time and cannot quickly take away the heat of the wort. Moreover, it is difficult to fully cool the wort that does not contact the inner wall of the cooling component 200. Therefore, by setting the auxiliary cooling component 300 communicated with the inner wall of the cooling component 200, the refrigerant in the inner cavity of the cooling component 200 can flow in the inner cavity of the auxiliary cooling component 300, and the auxiliary cooling component 300 is arranged in the inner cavity of the cooling component 200, so as to realize that the auxiliary cooling component 300 can cool the wort in the inner cavity of the cooling component 200.

[0045] On the above basis, the specific structure is disclosed in detail:

[0046] As Figures 2-5 shown, in order to enable the cooling component 200 to carry the cooled wort and allow the wort to ferment in the inner cavity of the cooling component 200, it is necessary to further disclose the parts of the cooling component 200. Therefore, the cooling component 200 includes a fermentation tank 210 fixedly connected to the bottom of the inner cavity of the support tank 120. The surface of the fermentation tank 210 is fixedly communicated with the end of the feed inlet 121. A sealing cover 230 is threadedly connected to the top of the fermentation tank 210. A stirring device 110 is rotatably connected to the bottom of the inner cavity of the fermentation tank 210;

[0047] A temperature sensor 240 is fixedly connected to the bottom of the inner cavity of the fermentation tank 210. By rotating the sealing cover 230 to separate the sealing cover 230 from the fermentation tank 210, at this time, the cooled wort is poured into the inner cavity of the fermentation tank 210. Then, an appropriate amount of yeast strain is put into the inner cavity of the fermentation tank 210, and the stirring device 110 is started to rotate, so that the yeast strain and the wort are fully mixed evenly, enabling the wort to ferment in the inner cavity of the fermentation tank 210.

[0048] As Figures 2-4 shown, considering that the yeast fermentation process is an exothermic reaction and generates heat. If the heat generated by the yeast is not removed in time, the ambient temperature around the yeast will rise. When the temperature exceeds the suitable growth range of the yeast, the activity of the yeast will be inhibited. Therefore, the inner wall of the fermentation tank 210 is provided with an empty groove 2101, and the empty groove 2101 is in a sandwich shape and is used to carry the circulating refrigerant.

[0049] The fermentation tank 210 is cylindrical, and the empty groove 2101 is cylindrical; by providing the empty groove 2101 on the inner wall of the fermentation tank 210, the refrigerant circulates on the inner wall of the empty groove 2101. At this time, the wort located in the inner cavity of the empty groove 2101 will contact the refrigerant through the fermentation tank 210, thereby achieving the cooling of the wort.

[0050] A spiral frame 220 is fixedly connected to the surface of the fermentation tank 210, and the spiral frame 220 is spirally wound around the outer wall of the fermentation tank 210;

[0051] A connection groove 2203 is provided on the contact surface between the spiral frame 220 and the fermentation tank 210, and the connection groove 2203 is fixedly communicated with the empty groove 2101;

[0052] As Figure 7As shown in the figure, the end of the spiral rack 220 is fixedly connected and communicated with a water inlet 2201, and the end of the spiral rack 220 far from the water inlet 2201 is fixedly connected and communicated with a water outlet 2202. By inputting the refrigerant from the water inlet 2201, the refrigerant entering the water inlet 2201 will reach the connection groove 2203 and the empty groove 2101, and continue to move upward until the empty groove 2101 and the connection groove 2203 are filled. At this time, the wort in the inner cavity of the fermentation tank 210 will contact the refrigerant through the fermentation tank 210, thereby cooling the wort. However, since the temperature generated by fermentation is continuous, at this time, a refrigerant with a continuously lower temperature is required to cool the wort. At this time, connect the water outlet 2202 to the water outlet pipe so that the water outlet 2202 can flow the refrigerant out of the empty groove 2101 and the connection groove 2203. During this process, since the spiral rack 220 is spiral and surrounds the outer wall of the fermentation tank 210, when the refrigerant flows on the inner wall of the connection groove 2203, it can guide the refrigerant to move along the preset spiral trajectory, extending the residence time and flow path of the refrigerant on the inner wall of the connection groove 2203, enhancing the heat exchange effect between the refrigerant and the outer wall of the fermentation tank 210, and making the flow of the refrigerant more stable and uniform, avoiding the problem of heat exchange imbalance caused by uneven refrigerant flow rate or local accumulation.

[0053] As Figures 3-4 shown, in order to enable the auxiliary cooling component 300 to cool the wort in the inner cavity of the fermentation tank 210, it is necessary to further disclose the parts of the auxiliary cooling component 300. Therefore, the auxiliary cooling component 300 includes a cooling pipe 310 fixedly connected to the inner wall of the fermentation tank 210, and a connection frame 320 is fixedly connected to the surface of the cooling pipe 310, and the end of the connection frame 320 is fixedly connected to the inner wall of the fermentation tank 210;

[0054] Specifically as Figure 8 shown, there are several cooling pipes 310, which are annularly distributed in the inner cavity of the fermentation tank 210. By distributing multiple cooling pipes 310 in the inner cavity of the fermentation tank 210 in an annular array and communicating with the fermentation tank 210, the wort in the inner cavity of the fermentation tank 210 in contact with the inner wall of the fermentation tank 210 can contact the cooling pipes 310, so that the cooling pipes 310 can cool the contacted wort.

[0055] As Figure 3 shown, in order to enable the refrigerant in the inner cavities of the empty groove 2101 and the connection groove 2203 to be transmitted into the cooling pipe 310, thereby cooling the wort in contact with the cooling pipe 310, therefore, a plurality of through holes are opened on the inner wall of the fermentation tank 210, and the inner wall of the through holes is fixedly communicated with the cooling pipe 310. As Figure 3, First, the refrigerant is introduced from the water inlet 2201 and first enters the empty tank 2101. As the refrigerant continues to enter, when it reaches the s1 position, since the cooling pipe 310 is connected to the fermentation tank 210, the refrigerant will flow into the inner cavity of the connected cooling pipe 310 along the trend and reach the s2 position inside the cooling pipe 310. Due to the continuous supply of the refrigerant, the refrigerant continuously flowing into the cooling pipe 310 will move steadily upward from the s2 position under the combined action of the pressure difference and gravity until it reaches the s3 position. At this time, below the s3 position, the refrigerant continuously surges upward. Under this pressure environment, the refrigerant at the s3 position will flow out from the s4 outlet along the path of the cooling pipe 310 and then smoothly return to the inner cavity of the empty tank 2101. The wort carried in the inner cavity of the fermentation tank 210 always keeps in close contact with the cooling pipe 310. At this time, the refrigerant in the inner cavity of the cooling pipe 310 will continuously take away the heat generated by the wort, thereby cooling the wort.

[0056] As Figure 1 shown, in order to enable the driving component 400 to transfer the refrigerant into the cooling component 200, it is necessary to further disclose the parts of the driving component 400. Therefore, the driving component 400 includes a water inlet pipe 410 fixedly connected to the end of the water inlet 2201. One end of the water inlet pipe 410 away from the water inlet 2201 is fixedly connected to a driving water pump 420. The bottom of the driving water pump 420 is fixedly connected to a box body 430. The end of the water outlet 2202 is fixedly connected to a water outlet pipe 440. By the operation of the driving water pump 420, the refrigerant in the box body 430 can be input into the water inlet pipe 410, and the refrigerant is transmitted to the water inlet 2201 through the water inlet pipe 410, and then the refrigerant is transferred to the water outlet 2202 by the water inlet 2201. Then, by continuously operating the driving water pump 420, the refrigerant fills the inner cavities of the empty tank 2101 and the connecting tank 2203. At this time, the excess refrigerant will flow out from the water outlet pipe 440.

[0057] As Figure 1 shown, in order to enable the water outlet pipe 440 to stably discharge the refrigerant from the connecting tank 2203, it is necessary to fix the water outlet pipe 440. Therefore, a pipe fixing frame 4401 is fixedly connected to the surface of the support tank 120. The inner wall of the pipe fixing frame 4401 is fixedly connected to the surface of the water outlet pipe 440. By setting the pipe fixing frame 4401 on the surface of the water outlet pipe 440 and then fixing the pipe fixing frame 4401 on the surface of the support tank 120, the pipe fixing frame 4401 can fix the water outlet pipe 440, so that the water outlet pipe 440 will not shake during the process of transmitting the refrigerant.

[0058] In summary, the overall working process is as follows:

[0059] First, rotate the sealing cover 230 to separate it from the fermentation tank 210, and pour the boiled and cooled wort into the inner cavity of the fermentation tank 210;

[0060] Pour an appropriate amount of yeast strain into the fermentation tank 210, and start the stirring device 110 to work, so that the wort and the yeast strain are evenly mixed to facilitate the subsequent fermentation of the wort. Rotate the sealing cover 230 to seal the wort in the inner cavity of the fermentation tank 210;

[0061] During the fermentation of the wort, the temperature sensor 240 monitors the temperature of the wort. If the monitored temperature of the wort is high;

[0062] At this time, the driving water pump 420 will transfer the refrigerant in the box body 430 to the water inlet 2201 through the water inlet pipe 410. The refrigerant will fill the connecting groove 2203 and the empty groove 2101 from the water inlet 2201, so that the temperature can be reduced when the wort in the inner cavity of the fermentation tank 210 contacts the fermentation tank 210.

[0063] During the process of filling the empty groove 2101, the refrigerant will reach the position s1, and then flow into the inner cavity of the cooling pipe 310 connected thereto, flow through s2 - s3 - s4 in sequence, and finally flow back to the empty groove 2101. At this time, the refrigerant in the inner cavity of the cooling pipe 310 will continuously take away the heat generated by the wort;

[0064] By continuously operating the driving water pump 420, the refrigerant fills the inner cavities of the empty groove 2101 and the connecting groove 2203. At this time, the excess refrigerant will flow out from the water outlet pipe 440.
