Technical Field

[0001] The utility model belongs to the technical field of wine making, and in particular relates to a fermentation tank. Background Art

[0002] Before entering the tank for fermentation, the mash with koji added is first piled up for fermentation. This piled fermentation process is an important stage in which a series of products of protein degradation are converted into pyrazine aroma components under certain conditions. The important factor affecting the growth metabolism of microorganisms and material conversion is temperature.

[0003] Traditional processes mostly involve placing the mash material in a fermentation tank for fermentation. However, during the fermentation process, the heat generated by the fermentation process usually makes the internal temperature of the fermentation tank uneven, thereby affecting the growth of microorganisms, causing the so-called "heartburn" in the winemaking process and affecting the quality of the wine.

However, most of the current fermentation tanks are sprayed with cooling water on the surface of the fermentation tank, which has a slow cooling speed and cannot quickly reduce the internal temperature of the fermentation tank to a suitable temperature in time, thereby affecting the fermentation effect.

[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] The utility model embodiment discloses a fermentation tank, the structure of which is as shown in the attached figure. Figure 1 As shown, it includes a fermentation tank body 1, a cover body 2, and a stirring component 3.

[0033] Specifically, the top of the fermentation tank body 1 is open, the tank wall is provided with an annular hollow chamber 11, and a cooling pipe 12 is provided at the center position of the interior. Among them, a drain pipe 111 is provided on the upper part of the side wall of the hollow chamber 11, and a water inlet pipe 112 is provided on the lower part of the side wall. The water inlet end of the cooling pipe 12 extends to the outside of the fermentation tank body 1 through the bottom of the fermentation tank body 1, and the water outlet end extends to the outside of the fermentation tank body 1 through the top of the tank wall of the fermentation tank body. When cooling is required, the cooling water source is connected, and cooling water is injected into the hollow chamber 11 and the cooling pipe 12, so as to cool the middle and outer parts of the fermentation tank body 1. The cooperation of the two can achieve rapid cooling, thereby avoiding excessively high temperature of the mash, affecting the production of microorganisms, and effectively improving the fermentation quality; at the same time, the hollow chamber 11 and the cooling pipe 12 both adopt the bottom water inlet method, which can increase the residence time of the cooling water, thereby facilitating the cooling effect.

[0034] The cover 2 is disposed on the top of the fermentation tank body 1, and a mutually matching snap-fitting structure is provided on one surface of the cover 2 and the top of the fermentation tank body 1. Specifically, a circular positioning boss 211 is provided on the top of the fermentation tank body 1, and a groove 212 is provided on one side of the cover 2 to match the positioning boss 211. The positioning boss 211 and the groove 212 are clearance-matched. The above-mentioned detachable structure is adopted to facilitate cleaning of the fermentation tank.

[0035] Considering that the fermentation tank needs good sealing performance, a sealing gasket is provided between the positioning boss 211 and the groove 212 to ensure the sealing performance inside the fermentation tank, which is beneficial to improving the fermentation effect.

[0036] The stirring assembly 3 is mounted on the cover 2, and includes a stirring shaft 31 and a driving mechanism 32. Among them, a plurality of stirring shafts 31 are evenly arranged around the cooling pipe 12, and stirring blades 33 are provided thereon. The driving mechanism 32 is connected to the stirring shaft 31 by transmission to drive the stirring shaft 31 to rotate. Thus, the stirring blades 33 are used to stir the fermented mash, which can not only mix the fermented mash raw materials evenly, but also keep the internal temperature of the fermented mash uniform, avoid local temperature overheating, and thus help improve the fermentation effect.

[0037] In this embodiment, the stirring blade 33 is a spiral blade, so that the mash can be rolled up and down, and the stirring effect is good.

[0038] Specifically, the driving mechanism 32 includes a sun gear 321, a planetary gear 322 and a motor 323. The sun gear 321 is arranged at the center of the cover 1; a plurality of planetary gears 322 are arranged around the sun gear 321 and mesh with the sun gear 321, and a shaft connected to the stirring shaft 31 is provided in the middle of the planetary gear 322. The motor 323 is connected to the sun gear 321 to drive the sun gear 321 to rotate, and drive the planetary gear 322 to rotate, thereby driving the stirring shaft 31 to rotate. With the planetary gear transmission device, the structure of the entire device is simple and the transmission performance is stable.

[0039] In some embodiments, in order to ensure smooth fermentation, sufficient oxygen needs to be supplied to the fermentation tank, so in this embodiment, an air intake assembly 4 is also provided. Specifically, the air intake assembly 4 includes a high-pressure nozzle 41 disposed at the bottom of the fermentation tank body 1 and an air pipe connecting the high-pressure nozzle 41 and the air pump, so as to add oxygen to the fermentation tank body 1, which is beneficial to improving the fermentation quality.

[0040] It is understandable that the oxygen source may be a high-concentration oxygen tank, thereby preventing impurities and other gases from mixing in.

[0041] More specifically, in order to ensure the safety of the fermentation tank, the cover body 2 is further provided with an air outlet pipe 22 which is in communication with the interior of the fermentation tank body 1 , and a safety valve is provided on the air outlet pipe 22 .

[0042] In some embodiments, in order to facilitate temperature control, a temperature sensor for monitoring the temperature of the fermented grains is also included (not shown in the drawings). When the temperature sensor detects that the temperature of the fermented grains is too high, an external water source is connected to inject cooling water into the hollow chamber 11 and the cooling pipe 12 to cool the fermented grains.

[0043] It is understandable that a control system may also be included, which is connected to the temperature sensor signal and can control the injection time of cooling water according to the signal of the temperature sensor, thereby achieving automatic cooling, which is beneficial to reducing the labor intensity of workers. This is common in the prior art.

[0044] As a specific implementation of the above embodiment, in order to facilitate the installation of the cover body 2, the cover body 2 is also provided with a handle for hoisting or for staff to take (not shown in the drawings).

[0045] It can be seen from the above description that the working principle and beneficial effects of the embodiment of the utility model are:

[0046] By providing the hollow chamber 11 and the cooling pipe 12, the mash can be cooled from both the inside and the outside, thereby achieving rapid cooling, avoiding the mash temperature being too high, affecting the production of microorganisms, and effectively improving the fermentation quality; further, a stirring component 3 is provided to stir the mash, and the driving mechanism 32 adopts a planetary gear transmission structure.
