Description

Technical Field

[0001] The utility model relates to equipment for brewing wine, in particular to a fermentation device. Background Art

[0002] In the prior art, during the fermentation of wine (such as pile fermentation, cellar fermentation, etc.), due to the lack of means to adjust the temperature of the fermented mash, there is a disadvantage that the temperature of the fermented mash is uncontrollable, resulting in an uncontrollable fermentation process. However, there is an optimal fermentation temperature or temperature range at each stage of the fermentation process. If the actual temperature curve in the fermentation is highly consistent with the optimal temperature curve, a higher quality fermentation product can be obtained. Utility Model Content

In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is a fermentation device for winemaking, comprising a fermentation tank, characterized in that the fermentation tank is divided into an upper chamber for placing the fermented grains and a lower chamber for storing yellow water by a sieve plate, a temperature sensor is provided in the upper chamber, and the sieve plate allows liquid and gas to pass through; the upper chamber and the lower chamber are connected by a conduit, and a temperature regulating medium composed of gas and / or liquid flows in the conduit, and the temperature regulating medium is mixed with the fermented grains in the upper chamber during the flow; the conduit is provided with a pressurizing component for the temperature regulating medium, and the conduit is provided with a heat exchanger for the temperature regulating medium.

[0004] The beneficial effect of the utility model is that liquid (such as yellow water and / or water) or gas (such as air) is used as a temperature regulating medium, the temperature regulating medium flows between the upper chamber and the lower chamber through a conduit, and the temperature of the temperature regulating medium is adjusted and controlled by a heat exchanger as needed, and the pressure component is operated according to the signal of the temperature sensor to control whether the temperature regulating medium flows and its flow rate as needed.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the principle structure of an embodiment. DETAILED DESCRIPTION

[0011] See attached Figure 1 , reflecting a specific structure of the utility model. The fermentation device for brewing wine comprises a fermentation tank 1, which is divided into an upper chamber 8 for placing fermented grains 10 and a lower chamber 15 for storing yellow water by a sieve plate 11. A temperature sensor (not shown in the figure) for measuring the temperature of each part of the sampled fermented grains 10 is arranged in the upper chamber 8. The sieve plate 11 allows liquid and gas to pass through, but can ensure that the fermented grains 10 will not leak under the sieve.

[0012] In the example, the fermentation tank 1 is provided with a one-way exhaust valve 6 for discharging fermentation gas (mainly carbon dioxide) to the outside.

[0013] In the example, liquid (such as yellow water and / or water) and gas (such as air) are used as temperature regulating medium to regulate and control the temperature of the fermented grains 10. In other embodiments, liquid or gas can be used alone as the temperature regulating medium to effectively control the temperature of the fermented grains 10.

[0014] In the example, the upper chamber 8 and the lower chamber 15 are connected through the first conduit 7 and the second conduit 2, respectively. The temperature regulating medium flows in the first conduit 7, and the liquid temperature regulating medium flows in the second conduit 2. The temperature regulating medium is mixed with the fermented grains 10 in the upper chamber 8 during the flow process to fully conduct and exchange heat, thereby achieving the purpose of temperature regulation.

[0015] In the example, the first conduit 7 is provided with a pressurizing component of the gas temperature control medium, namely a fan 13, and the first conduit 7 is provided with a first heat exchanger 12 of the gas temperature control medium. The heat exchanger adjusts and controls the temperature of the temperature control medium as required.

[0016] The fan 13 extracts air from the upper chamber 8, adjusts the temperature (can be heated or cooled) through the first heat exchanger 12, and then sends it to the lower chamber 15; the air passes through the sieve plate 11 and enters the upper chamber to mix with the mash 10 to fully conduct and exchange heat, and then passes through the mash 10 and is extracted by the fan 13 again, and the purpose of temperature regulation is achieved by such a cycle. The fan 13 works intermittently according to the signal of the temperature sensor, controls whether the air flows according to the need, and can also control the air flow rate.

[0017] In the example, the first conduit 7 is provided with an air inlet 9, and the air inlet 9 is connected to an air source through an openable / closable damper. The air source is selected from air, oxygen or carbon dioxide. The fermentation tank can be supplemented with corresponding gas according to the needs of the fermentation process, which is not only conducive to improving the fermentation quality, but also the fermentation tank can complete both stacking fermentation and cellar fermentation, avoiding the traditional process of transferring the raw materials to the fermentation tank for cellar fermentation after stacking fermentation.

[0018] In the example, the second conduit 2 is provided with a pressurizing component of the liquid temperature regulating medium, namely, a water pump 16, and the second conduit 2 is provided with a second heat exchanger 17 for the liquid temperature regulating medium. The solenoid valve 14 is opened, and the water pump 16 extracts the yellow water and / or water in the lower chamber 15, and sends it to the upper chamber 8 after adjusting the temperature through the second heat exchanger 17: Specifically, the top of the fermentation tank 1 is provided with a spray pipe 3 driven by a motor drive component 5, and the spray pipe 3 is connected to the second conduit 2, and the rotating spray pipe 3 evenly sprays the liquid temperature regulating medium sent to the upper chamber on the mash 10. The water pump 16 works intermittently according to the signal of the temperature sensor.

[0019] In the example, the second conduit 2 is provided with a yeast feeding port 4 that can be opened / closed, so as to facilitate adding yeast along with the liquid temperature regulating medium according to the needs of the fermentation process.

[0020] The utility model effectively regulates and controls the temperature of the fermented grains during the fermentation process according to the signal of the temperature sensor, when the temperature regulating medium passes through the fermented grains in the upper cavity and enters the lower cavity, so that the actual temperature curve in the fermentation is more consistent with the optimal temperature curve, thereby obtaining a fermentation product of higher quality, such as effectively reducing the bitter fusel oil.
