Description

Technical Field

[0001] The utility model relates to the technical field of liquor fermentation, in particular to a yellow water micro-fermentation device connected in series with a Luzhou-flavor liquor cellar. Background Art

[0002] The fermentation of Luzhou-flavor liquor is carried out in traditional mud pits through solid-state fermentation, solid-state distillation, aging, and blending. No flavor substances other than those produced by the fermentation itself are added directly or indirectly. In the national standard for Luzhou-flavor liquor (GB / T10781.1-2021), ethyl hexanoate and its precursor hexanoic acid are defined as its characteristic flavor substances. Relatively speaking, the higher-quality "superior" Luzhou-flavor liquor also has a higher content of ethyl hexanoate (150-200%). In the traditional Luzhou-flavor liquor fermentation process, the highest-quality Luzhou-flavor liquor of the year often comes from the pressed-cell liquor with the longest fermentation time; the best Luzhou-flavor liquor in a cellar is often distilled from the bottom fermented grains that coexist with "yellow water", a liquid by-product of Luzhou-flavor liquor fermentation, indicating the importance of "yellow water" fermentation to the fermentation quality of Luzhou-flavor liquor.

[0003] Yellow water is a liquid byproduct of the fermentation process of Luzhou-flavor liquor and the only liquid phase during its solid-state fermentation. It contains a large amount of nutrients and microorganisms. The sufficient fermentation of microorganisms in yellow water is more conducive to improving the fermentation quality of Luzhou-flavor liquor. However, in conventional Luzhou-flavor liquor solid-state fermentation carried out in traditional mud cellars, the cellar, as a solid-state fermentation container, cannot be equipped with a stirring device to ensure uniform mixing of the fermentation liquid phase, unlike liquid fermentation tanks. Insufficient yellow water fermentation affects the fermentation quality of the Luzhou-flavor liquor fermentation cellar. The yellow water sinks due to gravity, resulting in a significant difference in quality between the upper and lower parts of the cellar. Research has found that micro-fermentation of yellow water can significantly increase the content of caproic acid, a characteristic flavor component of Luzhou-flavor liquor. In actual anaerobic fermentation of Luzhou-flavor liquor, it is impossible to extract the yellow water and expose it to oxygen. Therefore, a yellow water micro-fermentation device that can be coordinated and connected in series with the Luzhou-flavor liquor cellar is needed. Utility Model Content

[0029] like Figure 1-3 As shown, the embodiment of the present invention provides a yellow water micro-fermentation device connected in series with a Luzhou-flavor liquor cellar, comprising:

[0030] The anaerobic static micro-fermentation tank 1 has a water inlet and a water outlet. The side wall of the anaerobic static micro-fermentation tank 1 is provided with at least one set of cleaning holes, and the cleaning holes are detachably covered with a cleaning cover plate 1a. The side wall of the anaerobic static micro-fermentation tank 1 is also provided with a longitudinally arranged sight glass 1b to facilitate observation of the liquid level changes.

[0031] A water inlet pipe 2, one end of which is connected to the water inlet, and the other end of which extends into the bottom of the Luzhou-flavor liquor cellar 100;

[0032] The first pump body 3 is installed on the water inlet pipe 2;

[0033] A return water pipe 4, one end of which is connected to the water outlet, and the other end of which extends into the bottom of the Luzhou-flavor liquor cellar 100;

[0034] The second pump body 5 is installed on the return water pipe 4;

[0035] Wherein, through the cooperation of the first pump body 3 and the second pump body 5, the yellow water at the bottom of the Luzhou-flavor liquor cellar 100 is continuously pumped into the anaerobic static micro-fermentation tank 1 for micro-fermentation.

[0036] In the embodiment of the present invention, by configuring an anaerobic static micro-fermentation tank 1 and connecting it to the Luzhou-flavor liquor cellar 100 through configuring a water inlet pipe 2 and a return pipe 4, the yellow water at the bottom of the Luzhou-flavor liquor cellar 100 can be continuously pumped into the anaerobic static micro-fermentation tank 1 for micro-fermentation, thereby helping to increase the content of characteristic flavor components in the yellow water and improve the fermentation quality.

[0037] Optionally, the anaerobic static micro-fermentation tank 1 is mainly made of stainless steel and has a horizontal cylindrical shell structure.

[0038] Optionally, the first pump body 3 and the second pump body 5 both use food-grade vacuum water pumps, which provide power for extracting yellow water. They are mainly made of food-grade stainless steel 316L, and the diaphragm and check valve therein are made of FDA-certified EPDM (ethylene propylene diene monomer rubber) or NBR (nitrile rubber) and other materials.

[0039] As an optional embodiment, a carrying trolley 6 is further provided at the bottom of the anaerobic static micro-fermentation tank 1, and the carrying trolley 6 is fixedly connected to the anaerobic static micro-fermentation tank 1 via a fixed bracket. In this way, the anaerobic static micro-fermentation tank 1 can be conveniently moved between different Luzhou-flavor liquor cellars 100 as needed.

[0040] As an optional embodiment, a sample addition tube 10 is provided at the top of the anaerobic static micro-fermentation tank 1. The sample addition tube 10 is longitudinally provided with two sample addition valves, the first of which is located at the top opening of the sample addition tube 10. This configuration of the sample addition tube 10 facilitates the addition of an appropriate amount of water, pH adjuster, etc. to the anaerobic micro-fermentation tank when needed. To avoid disrupting the anaerobic or micro-anaerobic environment in the anaerobic static micro-fermentation tank 1, the sample addition tube 10 is provided with two sample addition valves. When adding samples, the lower sample addition valve is first closed, the upper sample addition valve is opened, and the valve is closed after the material is added. The lower sample addition valve is then opened to allow the material to enter the anaerobic static micro-fermentation tank 1.

[0041] The sampling valve is equipped with a PC (polycarbonate) gasket to ensure absolute sealing when closed. PC material is often used to make baby bottles, space cups, etc. It is safe and hygienic.

[0042] As an optional embodiment, a safety valve 9 and a pressure gauge 12 are provided on the top of the anaerobic static micro-fermentation tank 1. In this way, the pressure in the anaerobic static micro-fermentation tank 1 can be effectively prevented from being too high.

[0043] Optional, such as Figure 4As shown, the safety valve 9 includes a safety pipe 9a, the first end of which is connected to the anaerobic static micro-fermentation tank 1, and is provided with an inner safety valve 9b at the first end and an outer safety valve 9c at the second end. At least two bends are provided between the first and second ends of the safety pipe 9a, and a three-way valve 9d is provided at the lower bend. When the anaerobic static micro-fermentation tank 1 is in operation, the inner safety valve 9b is kept normally open, and the outer safety valve 9c and the three-way valve 9d are kept normally closed. When the pressure in the anaerobic static micro-fermentation tank 1 needs to be released, the inner safety valve 9b is closed and the outer safety valve 9c is opened. The inner safety valve 9b and the outer safety valve 9c are repeatedly opened alternately. This can achieve the purpose of pressure relief and prevent air from entering the anaerobic static micro-fermentation tank 1 through the safety valve 9. After the pressure relief is completed, during the pressure relief process, the condensed liquid caused by the meeting of hot and cold air in the safety pipe 9a is collected at the lower bend. Close the safety inner valve 9b and open the three-way valve 9d to discharge the condensed liquid.

[0044] Optionally, in order to improve the stability of the safety tube 9a, the safety valve 9 is further provided with a safety bracket 9e, the two ends of which are respectively connected to the safety tube 9a and the outer wall of the anaerobic static micro-fermentation tank 1, thereby supporting the safety tube 9a.

[0045] As an optional embodiment, the outer wall of the anaerobic static micro-fermenter 1 is equipped with an instrument panel, a pH display 1d, a power switch 1e, and a temperature regulator 1c. This facilitates real-time monitoring of important parameters within the anaerobic static micro-fermenter 1, such as the pH value and fermentation temperature. The power switch 1e is connected to the temperature regulator 1c, which is connected to an attached heating wire for continuously monitoring and controlling the temperature within the anaerobic static micro-fermenter 1 to maintain the desired temperature range.

[0046] As an optional embodiment, the return water pipe 4 is longitudinally arranged in the part extending into the anaerobic static micro-fermentation tank 1, and multiple three-way ball valves 8 are arranged at intervals, so as to adjust the return water position of the return water pipe 4 returning water to the anaerobic static micro-fermentation tank 1.

[0047] As an optional implementation, a speed limiting valve 7 and a connecting valve 11 are provided on both the water inlet pipe 2 and the water return pipe 4 .

[0048] Optionally, the water inlet pipe 2 and the return pipe 4 both use polytetrafluoroethylene hose (PTFE hose) or ultra-high molecular weight polyethylene hose (UPE hose) or ethylene propylene diene monomer rubber hose (EPDM hose) or food-grade PVC steel wire pipe (FDA plasticizer-free) commonly used in the food field, all of which have the properties of wear resistance, corrosion resistance and resistance to the acidic environment of yellow water; the connecting valve 11 uses a flange connection that can withstand high pressure to cope with the high pressure caused by the gas generated during the anaerobic fermentation process of the micro-fermentation device.

[0049] Optionally, the above valves (speed limiting valve 7, connecting valve 11 and three-way ball valve 8) are all made of food-grade stainless steel 304 or 316L, and the parts in contact with the medium are mirror-polished to meet hygiene standards.

[0050] Working principle:

[0051] The anaerobic static micro-fermentation tank 1 is connected to the Luzhou-flavor liquor fermentation tank through the water inlet pipe 2 and the water return pipe 4. The directional flow of yellow water in the anaerobic static micro-fermentation tank 1 and the Luzhou-flavor liquor fermentation tank is achieved through the first pump body 3 and the second pump body 5. The temperature of the yellow water in the anaerobic static micro-fermentation tank 1 is controlled by the temperature regulator 1c. The pH value display 1d and the sampling tube 10 are used to control the pH value and add samples of the yellow water in the anaerobic static micro-fermentation tank 1. The pressure inside the anaerobic static micro-fermentation tank 1 is safely controlled by the pressure gauge 12 and the safety valve 9. The anaerobic static micro-fermentation tank 1 is moved by the carrying trolley 6.

[0052] This device provides a movable and controllable anaerobic micro-fermentation environment connected in series with the fermentation system of Luzhou-flavor liquor. After micro-fermentation, the yellow water is returned to the Luzhou-flavor liquor fermentation cellar. It can be used to increase the fermentation depth of the liquid-phase yellow water of Luzhou-flavor liquor, which is beneficial to increase the content of characteristic flavor components in the yellow water and improve the fermentation quality.
