Description

Technical Field

[0001] This utility model relates to the field of brewing equipment technology, and in particular to a fermentation device for brewing. Background Technology

[0002] Brewing is the process of producing alcoholic beverages with a certain concentration through microbial fermentation. However, in existing fermentation tanks, the alcohol mixture is not agitated sufficiently during use, resulting in incomplete and insufficient fermentation.

[0003] The alcohol mixture contains methanol, an impurity. To improve the quality of the alcohol, it needs to be removed during fermentation. Currently, the common method is to heat the alcohol mixture based on its different boiling points for evaporation. With existing technology, methanol has a boiling point of 64.7℃ and alcohol has a boiling point of 78.3℃. The mixture is heated using a heater before being fed into the fermentation tank, thus raising the temperature of the fermentation tank.

[0004] As hot water is gradually introduced into the fermentation tank, the temperature of the tank gradually increases. If the temperature becomes too high, simply stopping the hot water supply is insufficient to quickly lower the temperature, causing methanol and alcohol to evaporate together and resulting in alcohol loss. Therefore, a fermentation device for brewing is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fermentation device for brewing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fermentation device for brewing includes a fermentation tank. The dome of the fermentation tank is provided with a feed pipe that extends downward into the fermentation tank. The inlet of the feed pipe inside the fermentation tank is connected to a conveying pipe located at the center of the fermentation tank. A rotating nozzle is provided at the lower end of the conveying pipe.

[0008] In a preferred embodiment, the inner wall of the fermenter is provided with a sandwich layer, which is an insulation layer filled with polyurethane foam.

[0009] In a preferred embodiment, the top surface of the fermenter is provided with a pressure reducing valve and an exhaust pipe, and the bottom of the fermenter is provided with a drain valve.

[0010] The fermenter is equipped with a double-layer spiral coil inside, which is designed as a cooling water pipe and a heating water pipe, respectively. The cooling water pipe and the heating water pipe are stacked one on top of the other. A cold water pump and a hot water pump are respectively installed on both sides of the outside of the fermenter. The cold water pump and the hot water pump are connected to the cooling water pipe and the heating water pipe in the fermenter, respectively. The cold water pump and the hot water pump are located on both sides of the fermenter and are staggered vertically.

[0011] In a preferred embodiment, the top end of the cooling water pipe is designed as a cooling water outlet, and the bottom end of the heating water pipe is designed as a hot water outlet. The cooling water outlet and the hot water outlet extend out of the fermentation tank and are connected externally.

[0012] In a preferred embodiment, the conveying pipeline is equipped with a temperature sensor for monitoring the internal temperature of the fermenter.

[0013] In a preferred embodiment, the fermenter is equipped with an isolation plate inside, which is installed below the top of the fermenter.

[0014] In a preferred embodiment, the isolation plate has a sealing ring on its edge, an installation hole for the conveying pipe to be inserted into the center of the isolation plate, and air vents and leakage holes on the edge of the isolation plate, wherein the diameter of the air vents is larger than the diameter of the leakage holes.

[0015] In a preferred embodiment, the sealing ring ensures the edge sealing of the isolation plate, and the water vapor generated by evaporation passes through the pores and leakage holes.

[0016] The beneficial effects of this utility model are:

[0017] The fermentation equipment proposed in this solution solves the problem that the internal temperature of the tank cannot be quickly controlled and adjusted during alcohol fermentation and purification, which affects the alcohol fermentation effect and increases production costs. Hot water pipes and cold water pipes are spirally stacked. Hot water pipes are used to heat the fermentation tank, while cold water pipes are used to achieve rapid heat exchange when the temperature is too high, reducing the amount of alcohol evaporation. At the same time, the fermentation tank can be kept in a relatively constant state, with precise temperature control, efficient purification, reduced costs, and guaranteed alcohol fermentation effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In this embodiment, refer to Figure 1-2 A fermentation device for brewing includes a fermentation tank 1. The inner wall of the fermentation tank 1 has a jacket, which is an insulation layer 2 filled with polyurethane foam. The insulation layer 2 is used to keep the fermentation tank 1 warm. A feed pipe 3 is installed on the dome of the fermentation tank 1, extending downwards into the fermentation tank 1. The inlet of the feed pipe 3 inside the fermentation tank 1 is connected to a conveying pipe 4, which is located at the center of the fermentation tank 1. A temperature sensor 14 is installed on the conveying pipe 4 to monitor the internal temperature of the fermentation tank 1.

[0023] The top surface of fermenter 1 is equipped with a pressure reducing valve 12 and an exhaust pipe 13, and the bottom of fermenter 1 is equipped with a drain valve 6. The pressure reducing valve 12 is used to ensure that the internal pressure of fermenter 1 is constant, while the drain valve 6 is used to discharge the water after fermentation.

[0024] A rotating nozzle 5 is installed at the lower end of the conveying pipe 4. On the one hand, the rotating nozzle 5 can continuously deliver the alcohol introduced from the feed pipe 3 into the fermentation tank 1. On the other hand, the rotating nozzle 5 can guide the flow of alcohol by rotating, thereby accelerating the contact between the alcohol and the heating pipe in the fermentation tank 1 and increasing the fermentation rate.

[0025] Fermentation tank 1 is equipped with a double-layer spiral coil, as shown in the attached diagram. Figure 1 As shown, the double-layer spiral coil is designed as a cooling water pipe 7 and a heating water pipe 9, which are stacked one on top of the other.

[0026] A cold water pump 8 and a hot water pump 10 are respectively installed on the two sides of the outside of the fermentation tank 1. The cold water pump 8 and the hot water pump 10 are respectively connected to the cooling water pipe 7 and the heating water pipe 9 in the fermentation tank 1. The cold water pump 8 and the hot water pump 10 are located on both sides of the fermentation tank 1 and are staggered vertically.

[0027] The top end of the cooling water pipe 7 is designed as a cooling water outlet 71, and the bottom end of the heating water pipe 9 is designed as a hot water outlet 91. The cooling water outlet 71 and the hot water outlet 91 extend out of the fermentation tank 1 and are connected externally.

[0028] The fermenter 1 is equipped with an isolation plate 11, which is installed below the top of the fermenter 1. The isolation plate 11 has a sealing ring 1101 on its edge, and an installation hole 1102 for the conveying pipe 4 to be inserted is opened in the center of the isolation plate 11. The isolation plate 11 has an air hole 1103 and a leakage hole 1104 on its edge. The diameter of the air hole 1103 is larger than the diameter of the leakage hole 1104.

[0029] When processing methanol, only the hot water pump 10 operates. The hot water pump 10 introduces hot water into the heating water pipe 9 of the fermentation tank 1. The alcohol vapor in the fermentation tank 1 comes into contact with the heating water pipe 9, rapidly raising the temperature and thus evaporating the methanol into a gaseous phase. The isolation plate 11 serves as a barrier. The methanol vapor that evaporates first enters the upper layer through the vent 1103 and can eventually be discharged out through the exhaust pipe 13.

[0030] Temperature sensor 14 monitors the temperature inside the tank in real time. Once the temperature of the tank is too high, the alcohol will also be heated and evaporated into a gas phase. The cold water pump 8 will be started to send cooling water into the cooling water pipe 7 of the fermentation tank 1. The cooling water pipe 7, heating water pipe 9, and alcohol mixture are all kept in contact, so that the temperature of the fermentation tank 1 can be quickly reduced.

[0031] The cooling water pipe 7 and the heating water pipe 9 simultaneously transport cold and hot water, which can maintain the internal temperature of the tank at a relatively constant state, achieve precise temperature control, and ensure that the tank is at a suitable temperature to evaporate all the methanol. This is the alcohol purification process.

[0032] After the alcohol purification is complete, hot water is supplied to raise the tank temperature again, and then cooling water is supplied to maintain a constant tank temperature for alcohol fermentation.

[0033] Finally, the liquid remaining in the tank is discharged from the bottom of fermenter 1.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
