Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquor brewing devices, and particularly relates to a double-layer liquor stainless steel fermentation tank with a temperature control function. BACKGROUND

[0002] Liquor brewing is a process of generating an alcohol beverage containing a certain concentration of alcohol through microbial fermentation. During fermentation, raw materials are generally placed in a fermentation tank, and microorganisms are used to ferment the raw materials into liquor in a specific environment. During fermentation, the temperature in the fermentation tank needs to be kept constant. In the traditional way, heat preservation materials are used for heat preservation, and heating or cooling methods are used to keep the temperature in the fermentation tank constant.

[0003] The existing fermentation tank usually adopts a double-layer tank body. Heating wires are arranged between the double-layer tank body for heating, and heat preservation materials are arranged between the heating wires and the outer tank body for heat preservation. However, since the heating wires and the heat preservation materials have service lives, the existing method of replacing the heating wires and the heat preservation materials usually involves taking out the inner tank body from the outer tank body and replacing the heating wires and the heat preservation materials. Although the above-mentioned existing technology can realize replacement of the heat preservation materials and the heating wires, it still has some defects.

[0004] 1. The above-mentioned replacement of the heating wires and the heat preservation materials needs to be performed when no fermentation work is performed. However, from the start of the fermentation work to the end of the fermentation work, usually several weeks are needed. If the heating wires or the heat preservation materials fail during this period, the fermentation work will fail, which seriously affects the quality of the liquor, and even the whole tank of fermentation liquid cannot perform the fermentation work, wasting production time.

[0005] 2. The existing temperature control method involves arranging heating wires on the outer wall of the tank body to control the temperature in the tank body. However, the heating wires can only heat when the temperature in the tank body decreases. However, during the fermentation process, the temperature in the tank increases, and the heating wires cannot cool down. Therefore, the heating wires cannot effectively control the temperature. In addition, the heating wires arranged on the outer wall of the tank body cannot uniformly transfer heat to the tank. This may cause uneven distribution of the temperature in the fermentation tank, affecting the stability and consistency of the fermentation process. SUMMARY

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example

[0031] A double-walled stainless steel fermentation tank for baijiu (Chinese liquor) with temperature control function, such as Figures 1-7 As shown, the system includes an inner tank 2 and an outer tank 1. The inner tank 2 is fitted inside the outer tank 1. The inner tank 2 and the outer tank 1 are fitted with the same top cover 3. The top cover 3 is installed on the top of the inner tank 2. An annular groove 18 is provided on the outer edge of the bottom of the top cover 3. An annular track 19 that matches the annular groove 18 is provided on the top of the outer tank 1. A through groove is opened on the side wall of the outer tank 1. A door panel 22 is installed in the through groove through a hinge 20 and a latch 21. Annular plates 11 are arrayed on the outer wall of the inner tank 2. The annular plate 11 and the longitudinal plate 12 form multiple insulation material installation positions. The top cover 3 is equipped with a driving device. The inner tank 2 is equipped with an automatic temperature control device. The top cover 3 is equipped with a first gas storage cylinder 15 connected to the automatic temperature control device through a connecting pipe 17. The first gas storage cylinder 15 is connected to the automatic temperature control device through a heating pipe and a cooling pipe. The top cover 3 and the outer tank 1 are rotatably connected through an annular groove 18 and an annular track 19. The top cover 3 and the inner tank 2 are fixedly connected.

[0032] The insulation material is installed at the insulation material mounting position between the inner tank 2 and the outer tank 1. The insulation material mounting position array is set on the outer wall of the inner tank 2, completely covering the outer wall of the inner tank 2. The annular plate 11 and longitudinal plate 12 that make up the mounting position do not abut against the outer tank 1.

[0033] In the process of fermentation work, it is found that the insulation material in one or more insulation material installation positions is aging, and when the top cover 3 is rotated, the outer tank body 1 is in a relatively static state, and the inner tank body 2 rotates with the top cover 3. When the insulation material in the invalid position is rotated to the door plate 22, the door plate 22 on the outer tank body 1 can be opened by opening the lock buckle 21 of the pipe tank door plate 22 under the action of the hinge 20. At this time, the insulation material in the door plate 22 position is exposed, and the invalid insulation material is quickly replaced by the operator. In the replacement process, since the replaced insulation material is small and convenient and fast to replace, the temperature instability in the inner tank body 2 can be effectively avoided, and the required fermentation temperature in the inner tank body 2 can be maintained stable.

[0034] The automatic temperature control device comprises a rotating shaft 6, the rotating shaft 6 is divided into a heating channel and a cooling channel, the heating channel is communicated with a heating pipe, and the cooling channel is connected with a cooling pipe. A plurality of groups of openings are arranged on the side wall of the rotating shaft 6 in a staggered manner, the staggered openings are divided into upper openings and lower openings, the upper end of the upper opening and the lower end of the lower opening are provided with limiting rings 9, the limiting rings 9 are provided with an annular sleeve 8 capable of moving up and down through a spring 10, the middle section of the annular sleeve 8 has a cavity, the upper section and the lower section of the annular sleeve 8 shield the staggered openings respectively, and the outer edge of the annular sleeve 8 is symmetrically provided with helical stirring blades 7. The stirring blades 7 have a cavity, the surface of the stirring blades 7 is arrayed with air outlets, the air outlets are provided with one-way valves, and the cavities of the stirring blades 7 and the cavity of the annular sleeve 8 are communicated.

[0035] A limiting block is arranged between the annular sleeve 8 and the rotating shaft 6, so that the annular sleeve 8 moves up and down while rotating with the rotating shaft 6, and the heating sheet and the cooling sheet always work to heat and cool the gas entering the heating channel and the cooling channel;

[0036] When the rotating shaft 6 is not rotating, the annular sleeve 8 is always between the two limiting rings 9 due to the action of the spring 10, and the upper section and the lower end of the annular sleeve 8 can shield the openings in the heating channel and the cooling channel, so as to avoid the entry of hot gas and cold gas, and keep the temperature in the inner tank body 2 stable;

[0037] When the temperature inside the inner tank body 2 rises, the rotating shaft 6 rotates forward, because the stirring blade 7 is spiral, and the annular sleeve 8 on the stirring blade 7 is slidably installed on the rotating shaft 6 between the two limiting rings 9 through the spring 10, when the rotating shaft 6 drives the stirring blade 7 to rotate forward, the stirring blade 7 will be pressed downward by the pressure of the liquid in the fermentation tank, at this time the annular sleeve 8 presses the spring 10 below, but the upper section of the annular sleeve 8 still covers the upper opening of the staggered opening, but the cavity of the limiting sleeve is sleeved at the lower opening, the cold gas in the cooling channel of the stirring shaft enters the cavity of the annular sleeve 8 through the lower opening, because the cavity of the annular sleeve 8 is communicated with the cavity of the stirring blade 7, the cold gas enters the stirring blade 7, and then enters the fermentation liquid in the inner tank body 2 through the air outlet hole on the stirring blade 7, and the cold gas is fully mixed with the fermentation liquid through the stirring blade 7, so that the fermentation liquid is quickly cooled to a suitable temperature, avoiding that the temperature in the fermentation tank is too high to affect the quality of fermentation;

[0038] Similarly, when the temperature inside the inner tank body 2 decreases, the rotating shaft 6 rotates reversely, the stirring blade 7 will be pushed upward by the lifting force of the liquid in the fermentation tank, at this time the annular sleeve 8 presses the spring 10 above, but the lower section of the annular sleeve 8 still covers the lower opening of the staggered opening, but the cavity of the limiting sleeve is sleeved at the upper opening, the hot gas in the heating channel of the stirring shaft enters the cavity of the annular sleeve 8 through the upper opening, because the cavity of the annular sleeve 8 is communicated with the cavity of the stirring blade 7, the hot gas enters the stirring blade 7, and then enters the fermentation liquid in the inner tank body 2 through the air outlet hole on the stirring blade 7, and the hot gas is fully mixed with the fermentation liquid through the stirring blade 7, so that the fermentation liquid is quickly heated to a suitable temperature, so as to realize the temperature control effect of the fermentation liquid in the inner tank body 2, the whole structure is simple, and it is not necessary to increase control equipment and lines to control the temperature control device again, so that the temperature control of the stirring blade 7 can be realized when the stirring blade 7 works, and the control of the whole fermentation process is more simple and convenient.

[0039] The bottle mouth of the first gas storage bottle 15 is provided with a plurality of openings, the openings are respectively connected with corresponding heating pipes and cooling pipes, the first gas storage bottle 15 is provided with a pressure sensor, and the first gas storage bottle 15 is connected with external pressurizing equipment.

[0040] In the process of controlling the temperature of the fermentation liquid, the gas in the first gas storage bottle 15 will decrease, and the pressure in the first gas storage bottle 15 will change, in order to make the gas in the first gas storage bottle 15 more smoothly enter the inner tank body 2, the pressure sensor is arranged to detect the pressure change in the first gas storage bottle 15, when the pressure in the first gas storage bottle 15 decreases, the pressurizing equipment starts to pressurize the first gas storage bottle 15, so as to ensure that the gas in the first gas storage bottle 15 smoothly enters the inner tank body 2.

[0041] The longitudinal plate 12 evenly divides the bottom of the inner tank 2 into multiple sectors, and the curvature of the sector is the same as the width of the heat preservation material installation position and the door plate 22.

[0042] When the heat preservation material is inspected or replaced, the heat preservation material installation position can be directly exposed by opening the door plate 22, and the heat preservation material arranged in the sector shape at the bottom of the inner tank 2 is also convenient for the operator to quickly take out, so that the overall heat preservation material is divided into installation position size, which is convenient for targeted maintenance or replacement, and even during the fermentation process, the replacement operation can still be performed, and the local replacement can avoid the temperature inconsistency in the inner tank 2, and ensure the stability of the temperature in the inner tank 2.

[0043] The first gas cylinder 15 is filled with nitrogen, the heating channel is provided with a heating sheet, the cooling channel is provided with a cooling sheet, the heating sheet can heat the nitrogen to 35°, and the cooling sheet can cool the nitrogen to 20°.

[0044] Nitrogen is an inert gas, which can avoid chemical reaction with the fermentation liquid, and by heating or cooling the nitrogen, according to the needs of the inner tank 2, the heated nitrogen or the cooled nitrogen is introduced into the fermentation liquid, which can have the effect of heating and cooling the fermentation liquid in the inner tank 2, by heating the nitrogen to 35° and then introducing it into the fermentation liquid for stirring by the stirring blade 7, the temperature of the fermentation liquid can be quickly raised to about 30°, and by cooling the nitrogen to 20° and then introducing it into the fermentation liquid for stirring by the stirring blade 7, the temperature of the fermentation liquid can be quickly lowered to about 25°, which ensures that the temperature range of the fermentation liquid in the inner tank 2 is continuously maintained between 25° and 30°, so that the fermentation temperature of the fermentation liquid reaches the best.

[0045] The driving device includes a motor 4, the motor 4 is installed on the upper end of the top cover 3 through a mounting frame, and the power output end of the motor 4 is connected with the top end of the rotating shaft 6 through a belt 5.

[0046] The motor 4 is a forward and reverse motor 4, which can drive the rotating shaft 6 to realize forward rotation and reverse rotation through the belt 5, so as to realize the descending or ascending of the stirring blade 7, and the cold air or hot air enters the inner tank 2 to mix with the fermentation liquid, so as to achieve the temperature control effect.

[0047] The top cover 3 is also provided with a feeding hopper 13, one side of the first gas cylinder 15 is provided with a suction pump connected with the inner tank 2, and the suction pump is provided with a detachable second gas cylinder 16. The center of the bottom end of the inner tank 2 is provided with a discharge pipe 14, the discharge pipe 14 penetrates the bottom of the outer tank 1, and control valves are arranged at the discharge pipe 14 and the feeding hopper 13.

[0048] Since the injection of gas into the inner tank 2 causes the internal pressure to increase, the injected gas can be pumped into the second gas cylinder 16 by the suction pump. Since the second gas cylinder 16 is detachably connected to the suction pump, and the first gas cylinder 15 and the second gas cylinder 16 can be replaced, the inert gas inside the gas cylinder can be repeatedly used, reducing the cost required for production.

[0049] The control module is also included, and a plurality of temperature sensors are arranged on the tank wall of the inner tank 2. The temperature sensors, the pressure sensor, the motor 4, the heating fins, the cooling fins, the suction pump, and the pressurizing device are all electrically connected to the control module.

[0050] When the temperature sensor inside the inner tank 2 senses a change in temperature, it sends a signal to the control module. The control module controls the motor 4 to rotate forward or reverse, and controls the corresponding heating fins or cooling fins to work, so as to heat or cool the gas in the corresponding pipeline. The gas at the appropriate temperature is dispersed into the inner tank 2 by the stirring blade 7 and mixed with the fermentation liquid. The pressure sensor senses a change in pressure and sends a signal to the control module. The control module controls the pressurizing device to work, pressurizes the first gas cylinder 15, and makes the gas at the appropriate temperature smoothly enter the inner tank 2. In order to avoid the internal pressure of the inner tank 2 being too large due to the injection of gas, the control module controls the suction pump to work and sucks the excess gas into the second gas cylinder 16. Through the above process, better temperature control of the inner tank 2 is achieved.

[0051] The above examples are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements should also be considered to fall within the protection scope of the present application.
