Description

Technical Field

[0001] The utility model specifically relates to a fermentation tank for optimizing fermentation conditions. Background Art

[0002] The fermentation tank is an external environment device for microorganisms to grow, reproduce and form products during the fermentation process. As a microbial cultivation reactor, it can mix materials evenly, disperse gases well in the liquid phase, suspend solid particles evenly in the liquid, and suspend or fully emulsify the other uneven liquid phase, thereby strengthening the mass transfer and heat transfer between materials. It replaces traditional fermentation containers such as cultivation bottles, sauce jars and wine cellars, and plays an important role in continuous large-scale production, increasing output and yield, and greatly improving efficiency and output.

[0003] However, when the existing fermentation tank is in use, the raw materials tend to gather at the bottom of the tank under the influence of their own gravity, resulting in the inability to quickly mix the bacteria and the fermentation liquid, which needs to be optimized.

[0004] Therefore, it is necessary to invent a fermentation tank that optimizes fermentation conditions to solve the above problems. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-3 A fermentation tank for optimizing fermentation conditions shown includes a tank body 1, a rotating shaft 2 disposed inside the tank body 1, and an optimization component 3 installed on the rotating shaft 2;

[0028] The optimization component 3 includes a plurality of blades 31 installed at the bottom end of the rotating shaft 2, a plurality of stirring rods 32 located above the blades 31 and connected to the rotating shaft 2, and a liquid spraying pipe 33 penetrating the rotating shaft 2;

[0029] The liquid spray pipe 33 is tilted, and a plurality of disturbance rods 34 are connected to the outside of the liquid spray pipe 33 to optimize the mixing rate of the fermentation liquid and the bacteria in the tank body 1 .

[0030] In one embodiment, each of the blades 31 is arranged in an arc shape and is inclined so that the bacteria at the bottom of the tank body 1 can be lifted up when the blades 31 rotate, and the bacteria will not be damaged due to excessive shear force. The number of the stirring rods 32 is not less than three, and they are evenly distributed in a circular array on the outside of the rotating shaft 2, which are used to stir the lifted bacteria again to increase the mixing rate of the bacteria and the fermentation liquid. The disturbance rods 34 are distributed on the left and right sides of the spray pipe 33, and the number of disturbance rods 34 on the side of the spray pipe 33 close to the rotating shaft 2 is less than the number of disturbance rods 34 on the other side. The disturbance rods 34 can stir and mix the mixed liquid in the upper layer of the tank body 1 as the spray pipe 33 rotates, and can also break the floating bubbles to achieve the defoaming function, thereby improving the fermentation quality of the bacteria.

[0031] In one embodiment, a motor 4 is also installed on the top of the tank body 1, and the top of the rotating shaft 2 is connected to the output end of the motor 4 to drive the rotating shaft 2 to rotate. An observation window 5 is installed on the front side of the tank body 1 to facilitate the staff to observe the fermentation process of the bacteria in the tank body 1. A feed pipe 6 is installed on the top of the tank body 1, and a discharge pipe 7 is installed at the bottom of the tank body 1. Support legs 8 are also installed at the four corners of the bottom of the tank body 1 to facilitate the staff to use the fermentation tank.

[0032] The specific implementation mode is as follows: when the utility model is in use, the staff will pass the bacteria and fermentation liquid to be fermented into the tank body 1 through the feeding pipe 6, and then start the motor 4 to make its output end rotate counterclockwise, thereby driving the rotating shaft 2 to rotate counterclockwise. At this time, the blade 31 located at the bottom end of the rotating shaft 2 will rotate counterclockwise accordingly to stir the bacteria and fermentation liquid at the bottom of the tank body 1. Since the blade 31 is arranged in an arc shape, it can be avoided that the blade 31 scratches the bacteria when rotating, and the inclined design allows the bacteria and fermentation liquid to be lifted up, so that the bacteria and fermentation liquid can roll upward. At the same time, the rotation of the rotating shaft 2 will also drive the stirring rod 32 to rotate, and stir and mix the raised mixed liquid, thereby increasing the mixing rate of the bacteria and the fermentation liquid. At the same time, the liquid spraying pipe 33 will also rotate with the rotation of the rotating shaft 2, and the liquid spraying pipe 33 obliquely inserted into the rotating shaft 2 will generate centrifugal force when it rotates around the axis of the rotating shaft 2, so that the bottom opening of the liquid spraying pipe 33 is The raised mixed liquid can enter the interior of the liquid spraying pipe 33, and then under the action of centrifugal force, the mixed liquid in the liquid spraying pipe 33 has a tendency to move away from the rotation center, and then is thrown upward through the top opening of the liquid spraying pipe 33, so that the mixed liquid at the bottom layer can be replaced with the mixed liquid at the top layer, so that the bacteria are no longer always gathered at the bottom of the tank body 1, and can be thrown upward, and under the action of gravity, while falling, they are stirred in turn by the liquid spraying pipe 33 itself, the orbiting rod, and the stirring rod 32, that is, the bacteria and the fermentation liquid at the bottom of the tank body 1 are tumbled, raised, stirred, mixed, thrown upward, and refluxed, so as to optimize the fermentation conditions inside the tank body 1, so that the mixing rate of the bacteria and the fermentation liquid is further accelerated, and a uniformly mixed state can be quickly achieved. When all the bacteria are fermented, the staff opens the discharge pipe 7 to collect the mixed liquid in the tank body 1, and then injects clean water to clean the inside of the tank body 1, and then the next batch of bacteria can be put into fermentation treatment;

[0033] This embodiment specifically solves the problem in the prior art that when the current fermentation tank is in use, the raw materials are easily gathered at the bottom of the tank body 1 under the influence of their own gravity, resulting in the inability to quickly mix the bacteria and the fermentation liquid, which needs to be optimized.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
