Description

Technical Field

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

[0002] Fermented alcoholic drink, also known as fermented alcohol or original juice alcohol, is made by fermenting starch and sugar raw materials with yeast to produce alcohol. Its production process includes saccharification, fermentation, filtration, sterilization, etc.

[0003] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microbial cells themselves, or direct metabolites or secondary metabolites. Fermentation is a biochemical reaction that humans have been exposed to for a long time, and the commonly used equipment for fermentation is the fermentation tank.

[0004] Fermentation tank refers to the device used for microbial fermentation in industry. Its main body is generally a main cylinder made of stainless steel plate, with a volume ranging from 1 cubic meter to several hundred cubic meters. It should have a tight structure and reasonable strength in design and processing. During fermentation, microorganisms need to be evenly distributed in the fermentation liquid, and the ammonia produced by fermentation is generally contained in the fermentation liquid, so the fermentation tank needs to be stirred.

[0005] The utility model patent with application number 202222582956.X discloses a fruit wine fermentation tank, which includes a tank body, a stirring member and an air supply pipe. A fermentation space is provided in the tank body. The stirring member includes a driving part, a driving connecting shaft and a plurality of stirring rods. The driving part is installed on the tank body, the driving connecting shaft is connected to the driving part and extends into the fermentation space along the length direction of the tank body, a ventilation channel is provided through the driving connecting shaft along the length direction, one end of the plurality of stirring rods is connected to the driving connecting shaft and the plurality of stirring rods are staggered along the length direction of the driving connecting shaft, an air outlet channel is provided in the stirring rod, an air outlet hole is provided on the stirring rod, and the air outlet hole and the air outlet channel are both connected to the ventilation channel; one end of the air supply pipe is connected to an end of the driving connecting shaft away from the driving part, and an end of the air supply pipe away from the driving connecting shaft extends outside the tank body; the driving connecting shaft can rotate relative to the air supply pipe. When the fruit wine fermentation tank is in use, the fermentation material is fermented in the tank body. When the fermentation liquid needs to come into contact with oxygen, filtered sterile air is supplied into the driving connecting shaft from the air supply pipe. Since the air outlet and the air outlet channel are both connected with the ventilation channel, the gas enters the fermentation space from the air outlet. While supplying air, the driving part drives a plurality of stirring rods to rotate in the fermentation space through the driving connecting shaft. Since the plurality of stirring rods are staggered along the length direction of the driving connecting shaft and the stirring rods extend in a direction away from the driving connecting shaft, the stirring rods can contact more fermentation material and fermentation liquid in the lateral direction of the tank body during rotation, thereby allowing the sterile air to more fully contact the fermentation material and fermentation liquid.

[0006] In addition, the utility model patent with application number 202321401262.X also discloses a fermentation tank capable of separating bubbles from inside the fermentation liquid, comprising a fermentation tank, an air injection pipe and a guide plate; the fermentation tank is a closed tank body, a stirring paddle is vertically arranged inside the fermentation tank, and a stirring motor is arranged outside the fermentation tank, the upper end of the stirring paddle extends out of the fermentation tank and is vertically connected to the driving shaft of the stirring motor, the driving shaft of the stirring motor is vertically arranged, and can continuously wrap the ammonia in the fermentation liquid through the bubbles of air through the injection of air, and take away the ammonia together, thereby reducing the ammonia concentration in the fermentation liquid, and can also stir the fermentation liquid up and down through the waterfall plate and the guide plate, so that the fermentation liquid is continuously raised to form a water curtain, thereby exposing the fermentation liquid in the gas, so that the ammonia in the fermentation liquid is fully separated from the liquid, thereby maintaining the pH value in the fermentation liquid stable.

[0007] For example, the fermentation tanks involved in the above two utility model patents both involve the installation of a stirring device in the fermentation tank, through which the gas, bacterial liquid and fermentation materials in the tank body are effectively stirred. However, in order to improve the stirring efficiency and stirring effect, most of the existing fermentation tanks are innovative in the shape structure of the stirring blades in the stirring device and the setting method of the stirring blades. Utility Model Content

[0008] The purpose of the utility model is to solve the technical problem that the prior art only improves the stirring effect and the stirring efficiency by the structure and setting of the stirring blades, thereby providing a mixed bacteria fermentation tank, which further improves the stirring effect and the stirring efficiency through multiple innovations such as the improvement of the bottom structure of the tank body, the reverse thrust achieved by the liquid inlet and the jet, and the up and down floating of the jet pipe.

[0021] 3. In the utility model, the outlet direction of the mash inlet pipeline is set to 20°≤β≤45°, 30°≤γ≤60°, 40°≤α≤55°. This can more effectively promote the rotation of the jet pipe during the mash spraying process, thereby improving the stirring effect of the gas, bacterial liquid and fermentation materials in the tank body.

[0022] 4. In the utility model, the air bag and the jet pipe are connected by means of a ball joint. On the one hand, the ball joint connection method can improve the smoothness of the sterile air entering the jet pipe through the air bag. On the other hand, it can also allow the jet pipe to have a certain space for up and down floating, so that the jet pipe can swing up and down during the rotation and stirring process under the push of the mash inlet pipeline, thereby improving the stirring effect of the gas, bacterial liquid and fermentation material in the tank.

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0032] Therefore, based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present utility model.

[0033] Example 1

[0034] This embodiment provides a mixed bacteria fermentation tank, which is used to stir and mix sterile gas, bacterial liquid and fermentation materials. It includes:

[0035] The fermentation tank 4 can be filled with mash and sterile air, so that the sterile gas, bacterial liquid and fermentation materials in the fermentation tank 4 are fully mixed and fermented. The bottom of the fermentation tank 4 is a tank inclined bottom 5, which is actually an inclined plane. Figure 2 shown.

[0036] The sterile air pipeline 3 is connected to the middle and lower part of the fermentation tank 4 and communicates with the inside of the fermentation tank 4. The sterile air pipeline 3 can be used to fill the tank body of the fermentation tank 4 with sterile air.

[0037] The mash inlet pipeline 6 is located below the sterile air pipeline 3, is connected to the middle and lower part of the fermenter 4, and is communicated with the inside of the fermenter 4. The mash can be filled into the tank body of the fermenter 4 through the mash inlet pipeline 6.

[0038] The tank top exhaust pipe 1 is located at the top of the fermentation tank 4, is connected to the top of the fermentation tank 4, and is communicated with the inside of the fermentation tank 4. The gas in the tank body of the fermentation tank 4 can be discharged through the tank top exhaust pipe 1.

[0039] The mash outlet pipeline 2 is located above the sterile air pipeline 3, connected to the middle and upper part of the fermentation tank 4, and communicated with the inside of the fermentation tank 4. The mash in the tank body of the fermentation tank 4 can be discharged through the mash outlet pipeline 2.

[0040] The air bag 7 is located inside the fermentation tank 4 and is installed on the tank inclined bottom 5 inside the fermentation tank 4 through the support base 9. The air bag 7 is installed on the support base 9 through conventional slots, bearings and other structures, that is, the installation of the air bag 7 is realized, and the air bag 7 can also rotate freely on the support base 9 (the air bag 7 and the support base 9, and the air bag 7 and the sterile air pipeline 3 are connected by existing conventional methods to ensure that sealing is achieved on the basis of rotation).

[0041] The jet pipe 8 is installed on the air bag 7 and is connected to the sterile air pipeline 3. The sterile air filled in the sterile air pipeline 3 can be transported to the jet pipe 8 through the air bag 7 and sprayed into the fermentation tank 4 through the jet hole 81 on the jet pipe 8.

[0042] In addition, the discharge port of the mash inlet pipeline 6 is arranged opposite to the end of the jet pipe 8, and the mash sprayed from the mash inlet pipeline 6 drives the jet pipe 8 to rotate.

[0043] When in use, sterile air and mash are respectively filled into the fermentation tank 4 through the sterile air pipeline 3 and the mash inlet pipeline 6, and the sterile air enters the jet pipe 8 through the air bag 7 and is ejected from the jet hole 81 on the jet pipe 8; the mash is ejected through the liquid outlet of the mash inlet pipeline 6 and is ejected to the free end of the jet pipe 8, and drives the jet pipe 8 to rotate on the air bag 7, thereby achieving stirring and mixing of the gas, bacterial liquid and fermented materials in the tank body; during the rotation of the jet pipe 8, since the bottom of the fermentation tank 4 is a slanted bottom 5, the material will also float up and down during the stirring process, thereby effectively improving the stirring effect of the gas, bacterial liquid and fermented materials in the tank body.

[0044] Example 2

[0045] On the basis of Example 1, the side of the jet pipe 8 facing the water when rotating is defined as the water-facing side, and the back side of the water-facing side of the jet pipe 8 is defined as the water-receiving side. Therefore, when the jet hole 81 is provided on the jet pipe 8, the jet hole 81 is provided on the water-receiving side of the jet pipe 8, and a plurality of jet holes 81 are provided on each jet pipe 8, and the plurality of jet holes 81 are evenly arranged along the length direction of the jet pipe 8.

[0046] When in use, since the jet pipe 8 jets backward, the jet pipe 8 will rotate under the action force and reaction force, thereby achieving stirring and mixing of the gas, bacterial liquid and fermentation materials in the tank.

[0047] Preferably, the outlet of the mash inlet pipeline 6 is set to be obliquely upward, and the angle between the outlet direction of the mash inlet pipeline 6 and the projection oY in the plane xoz is β, the angle between the outlet direction of the mash inlet pipeline 6 and the projection oZ in the plane xoy is γ, and the angle between the outlet direction of the mash inlet pipeline 6 and the projection oX in the plane zoy is α, and the angles β, γ, and α are all positive. Figure 6 shown.

[0048] The outgoing direction of the liquid outlet of the mash inlet pipeline 6 satisfies the following conditions:

[0049] 20°≤β≤45°, 30°≤γ≤60°, 40°≤α≤55°.

[0050] In this embodiment, by opening the jet hole 81 on the back water side of the jet pipe 8, based on the relationship between the action force and the reaction force, during the jetting process, the reaction force can drive the jet pipe 8 to rotate, which can further improve the stirring effect of the gas, bacterial liquid and fermented materials in the tank body; in addition, the outlet direction of the mash inlet pipeline 6 is set to 20°≤β≤45°, 30°≤γ≤60°, 40°≤α≤55°, which can more effectively drive the jet pipe to rotate during the mash spraying process, thereby improving the stirring effect of the gas, bacterial liquid and fermented materials in the tank body.

[0051] Example 3

[0052] On the basis of the above embodiment, a cylindrical groove 71 is provided at the lower end of the outer cylindrical surface of the air bag 7 , and a ball head groove 72 is provided in the cylindrical groove 71 .

[0053] A connecting ball head 82 is provided at the end of the connecting end of the air injection pipe 8 , and the connecting ball head 82 is matched with the ball head groove 72 .

[0054] During installation, the jet tube 8 is installed in the ball head groove 72 of the air bag 7 through the connecting ball head 82 (that is, the connecting ball head 82 is clamped in the ball head groove 72, and the connecting ball head 82 can rotate in the ball head groove 72), and the jet tube 8 can swing up and down after being installed on the air bag 7.

[0055] The upper limit of the swing of the air injection pipe 8 is OA, and the lower limit is OB. The angle θ between OA and OB satisfies the condition: 10°≤θ≤15°.

[0056] In this embodiment, the air bag 7 and the jet pipe 8 are connected by means of a ball joint. On the one hand, the ball joint connection method can improve the smoothness of the sterile air entering the jet pipe 8 through the air bag 7 (that is, the existing related structure that can achieve sealing under the ball joint condition can be adopted). On the other hand, it can also enable the jet pipe 8 to have a certain space for up and down floating, so that under the push of the mash inlet pipeline 6, the jet pipe 8 can also swing up and down during the rotation and stirring process, thereby improving the stirring effect of the gas, bacterial liquid and fermentation materials in the tank body.
