Description

Technical Field

[0001] The utility model relates to the technical field of bean fermentation, in particular to a sterile fermentation device for bean materials. Background Art

[0002] The sterile fermentation of bean materials is a fermentation process carried out by specific microorganisms under sterile conditions, aiming to improve the nutritional value and flavor of bean foods. The addition of microorganisms during the fermentation process of bean materials is to utilize the metabolic activities of microorganisms to decompose and transform the original substances in beans, generating new flavors and nutritional components, so as to obtain fermented bean products with specific flavors and functions. The selection and addition times of microorganisms directly affect the quality and functionality of the final products.

[0003] However, during the fermentation process of bean materials, it is necessary to add corresponding microorganisms to the fermentation device at different fermentation stages of the bean materials. Generally, a pipette or a syringe is used to add microorganisms to the fermentation device. Then, when the pipette or the syringe is used, the fermentation device needs to be opened, and then the addition operation is carried out quickly. The operation requirements are relatively high, and it is very likely that other miscellaneous bacteria will be added to the fermentation device during the operation, thereby affecting the fermentation process of the bean materials and the fermentation effect of the final products.

[0004] Based on the above situation, it is necessary to design a sterile fermentation device for bean materials to solve the above problems. Summary of the Utility Model

[0005] The utility model provides a sterile fermentation device for bean materials to solve the problem that miscellaneous bacteria are doped when adding microorganisms to bean materials in the prior art.

[0006] The technical problems solved by the utility model are realized by adopting the following technical solutions:

[0007] A sterile fermentation device for bean materials includes a fermentation barrel for containing bean materials. A bottom plate is rotatably connected in the fermentation barrel in a sealed manner. A plurality of tanks for containing different microorganisms are connected to the outer side wall of the fermentation barrel. Valves are arranged at the input end and the output end of each tank. The output end of the tank extends into the fermentation barrel. A piston is slidably connected in the tank in a sealed manner. A driving member for driving the piston to slide is arranged on the fermentation barrel. A control component for operating the driving member is arranged on the fermentation barrel.

[0008] Preferably, an input pipe fitting and an output pipe fitting are respectively communicated with the input end and the output end of the tank, and the two valves are respectively arranged on the input pipe fitting and the output pipe fitting.

[0009] Preferably, the control component includes a controller and a position sensor arranged on the tank body. The position sensor is used to sense and locate the position of the piston. After the controller receives the position signal from the position sensor, a control signal for controlling the operation of the driving member is output from the output end of the controller.

[0010] Preferably, an air exchange pipe is connected to a position on the side wall of the tank body near the bottom, and an air exchange valve is arranged on the air exchange pipe.

[0011] Preferably, an observation window is arranged on the side wall of the tank body, and a scale bar is arranged on the observation window.

[0012] Preferably, a stirring rod is rotatably connected inside the fermentation barrel, and a first motor is connected to the top of the fermentation barrel. The output end of the first motor is connected to the stirring rod.

[0013] Preferably, a fixing plate is arranged below the bottom plate, and a second motor is connected to the fixing plate. The output end of the second motor is connected to the lower end surface of the bottom plate.

[0014] The beneficial effects of the present utility model are as follows: By providing a tank body with airtightness outside the fermentation barrel, when microorganisms are introduced into the interior of the tank body, the valve at the input end of the tank body will be opened. After the introduction is completed, the valve will immediately close to ensure the airtightness of the tank body. Then, under the action of the driving member and the piston, the microorganisms inside the tank body are introduced into the fermentation barrel. During this process, the valve on the output end of the tank body is in an open state. After the microorganisms are introduced into the fermentation barrel, the valve immediately closes. At this time, the interior of the tank body returns to an airtight state again. The microorganisms are introduced and exported in an airtight state, so it is avoided that miscellaneous bacteria will be mixed into the fermentation barrel through the introduction and export of microorganisms, thereby avoiding the influence of the introduction of microorganisms on the fermentation process.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0022] Referring to Figures 1-4 as shown, a sterile fermentation device for bean materials includes a fermentation barrel 1 for containing bean materials. When in use, the bean materials are placed in the fermentation barrel 1. The bottom plate 2 is rotatably and sealingly connected inside the fermentation barrel 1. The bottom plate 2 will carry the bean materials placed inside the fermentation barrel 1. A plurality of tank bodies 3 for containing microorganisms are connected to the outer side wall of the fermentation barrel 1. Valves are provided at both the input end and the output end of the tank body 3, and the output end of the tank body 3 extends into the fermentation barrel 1. A piston 4 is slidably and sealingly connected inside the tank body 3. A driving member 5 for driving the piston 4 to slide is provided on the fermentation barrel 1. When microorganisms are placed inside the tank body 3, the driving member 5 can be used to drive the piston 4 to squeeze the air inside the tank body 3, so that the microorganisms are discharged from the output end of the tank body 3. A control component for operating the driving member 5 is provided on the fermentation barrel 1. The control component can control the running time and stroke of the driving member 5, and can control the driving member 5 to run regularly. When in use, the tank body 3 itself is in a closed state under the action of the two valves. The microorganisms are introduced through the valve at the input end of the tank body 3. During the introduction process, the valve makes the foreign microorganism container (not shown in the figure) and the tank body 3 in a closed state. The valve will be immediately closed after the microorganisms are introduced, so as to maintain the sealing of the tank body 3. After the microorganisms are located inside the tank body 3, they will be deposited at the bottom of the tank body 3. The driving component is used to drive the driving member 5 to drive the piston 4 to move, so as to squeeze and introduce the microorganisms inside the tank body 3 into the fermentation barrel 1. During this process, the valve at the output end of the tank body 3 is in an open state. After the microorganisms are introduced into the fermentation barrel 1, the valve is immediately closed. At this time, the inside of the tank body 3 returns to a closed state again and waits for the next use. In the above process, the microorganisms are introduced and discharged in a closed state, avoiding the mixing of miscellaneous bacteria during the introduction of the microorganisms, thereby affecting the fermentation process.

[0023] ​An input pipe fitting 6 and an output pipe fitting 7 are respectively connected to the input end and the output end of the tank body 3. Two valve bodies are respectively arranged on the input pipe fitting 6 and the output pipe fitting 7. The valve bodies in the above are respectively: the valve body on the input end of the tank body 3 is the one-way valve 60, and the valve body on the output end of the tank body 3 is the solenoid valve 70. When in use, microorganisms are introduced from the input end of the tank body 3. The one-way valve 60 can allow the introduction of microorganisms and prevent the reverse flow of microorganisms from the inside to the outside at the input end position of the tank body 3.

[0024] Among them, the control component includes a controller 9 and a position sensor 8 arranged on the tank body 3. The position sensor 8 is used to sense the position of the positioning piston 4. After the controller 9 receives the position signal of the position sensor 8, a control signal for controlling the operation of the driving member 5 is output from the output end of the controller 9. The driving member 5 can be a telescopic rod with electric control or other electric devices. Its main purpose is to drive the piston 4 to move and facilitate the control of the controller 9. When in use, after the microorganisms are introduced into the tank body 3, the controller 9 is started. The controller 9 controls the operation of the driving member 5, and the driving member 5 drives the piston 4 to slide. Then the solenoid valve 70 is opened, and the microorganisms inside the tank body 3 are squeezed and introduced into the fermentation barrel 1. And the microorganisms inside the tank body 3 will only be introduced into the fermentation barrel 1 when the piston 4 slides downward. Therefore, the travel distance of the driving member 5 driving the piston 4 is related to the amount of microorganisms introduced. The position sensor 8 can sense the position of the output end of the driving member 5 and the position where the piston 4 is located. Then the controller 9 controls the output distance of the driving member 5. A corresponding threshold value can be set in advance on the controller 9, thereby affecting the operation of the driving member 5.

[0025] The controller 9 and the driving members 5 on several tank bodies 3 can be electrically connected. The controller 9 can identify and separately control the operation of several driving members 5. When one of the driving members 5 needs to operate, it can be controlled only through the controller 9.

[0026] Secondly, the setting of several tank bodies 3 can also avoid cleaning the tank body 3 once for each use. Different types of microorganisms can be respectively introduced into different tank bodies 3 to prevent cross-contamination.

[0027] The solenoid valve 70 is electrically connected to the controller 9. The controller 9 outputs a control signal for controlling the operation of the solenoid valve 70. When it is necessary to introduce the microorganisms in one of the tank bodies 3 into the fermentation barrel 1, the operator uses the controller 9 to control the opening of the solenoid valve 70. When the solenoid valve 70 is not in use, it can prevent the penetration of microorganisms from the inside of the tank body 3 into the fermentation barrel 1.

[0028] Refer to Figure 4As shown, further, an air exchange pipe 10 is connected to the side wall of the tank body 3 near the bottom. One end of the air exchange pipe 10 is connected to the inside of the tank body 3, and the other end of the air exchange pipe 10 is connected to some air disinfection equipment (not shown in the figure) to prevent some miscellaneous bacteria from entering through the air exchange pipe 10. A ventilation valve 11 is provided on the air exchange pipe 10. When the piston 4 slides, the air pressure inside the tank body 3 is controlled by the ventilation valve 11. The ventilation valve 11 is a prior art structure, which can be a one-way valve for ventilation or other gas valves, and will not be elaborated. Its main purpose is to enable the flow of gas inside the tank body 3.

[0029] Referring to Figure 2 As shown, furthermore, a fixing plate 16 is provided below the bottom plate 2. A second motor 17 is connected to the fixing plate 16, and the output end of the second motor 17 is connected to the lower end surface of the bottom plate 2. When one of the tank bodies 3 introduces microorganisms into the fermentation barrel 1, the second motor 17 drives the bottom plate 2 to rotate, so that the upper layer of the bean material on the bottom plate 2 is evenly contacted with the microorganisms.

[0030] Referring to Figure 2 As shown, still further, a stirring rod 14 is rotatably connected inside the fermentation barrel 1. A first motor 15 is connected to the top of the fermentation barrel 1, and the output end of the first motor 15 is connected to the stirring rod 14. After the upper layer of the bean material is evenly contacted with the microorganisms, the first motor 15 is started to drive the stirring rod 14 to rotate, so that the microorganisms and the bean material are fully mixed. Before that, the rotation of the bottom plate 2 makes the effect of the stirring rod 14 better and the efficiency higher when stirring.

[0031] Referring to Figure 3 As shown, among them, an observation window 12 is provided on the side wall of the tank body 3, and a scale bar 13 is provided on the observation window 12, which is convenient for the operator to observe the situation of the microorganisms inside the tank body 3 and to estimate the capacity of the microorganisms.
