Description
Technical Field
[0001] The utility model relates to the technical field of food fermentation, and particularly relates to a fermentation device based on biological detection. Background Technique
[0002] A fermentation device based on biological detection is an advanced fermentation system (device) integrating biological detection technology. It realizes precise control and optimization of the fermentation process by real-time monitoring of biological parameters during fermentation. The device is internally provided with a variety of biological sensors or detection modules, which can real-time monitor key biological parameters such as the concentration of microorganisms, the content of metabolites, and the enzyme activity in the fermentation broth. These biological detection technologies include, but are not limited to, optical detection, electrochemical detection, biochip technology, etc., and have high sensitivity, high selectivity, and real-time performance. By real-time monitoring of biological parameters, the device can automatically adjust fermentation conditions such as temperature, pH value, dissolved oxygen content, stirring speed, etc., to maintain the optimal growth and metabolic state of microorganisms.
[0003] In order to improve fermentation efficiency, improve product quality, and enhance production stability, sterile oxygen is injected into the tank body. (Many food fermentation processes rely on aerobic microorganisms such as acetic acid bacteria and yeast. Uniform injection of sterile oxygen can provide sufficient oxygen for these microorganisms, enabling their respiration to proceed smoothly, thereby accelerating the growth, reproduction, and metabolic activities of microorganisms. For example, in the acetic acid fermentation process, acetic acid bacteria need oxygen to oxidize ethanol into acetic acid. Sufficient oxygen supply can significantly improve the activity of acetic acid bacteria and accelerate the production rate of acetic acid, shortening the fermentation cycle).

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: This fermentation device based on biological detection has the following advantages compared with the traditional technology:
[0013] Through the cooperation among the tank body, the tank cover, the sensor integration box, the feeding hopper and the stirring unit, the user first puts an appropriate amount of materials to be mixed and fermented into the tank body through the feeding hopper, closes the top baffle of the feeding hopper, and starts the motor to enable the two stirring pipes to mix and stir the materials inside the tank body. During this period, by opening and closing the valve, oxygen is injected into the inside of the riser pipe, the circular pipe, the cavity block and the stirring pipe through the connecting pipe. After the oxygen enters the inside of the stirring pipe, it will be discharged from the air outlet holes and act on the materials. In this process, because the two stirring pipes continuously revolve around the circular pipe, the position of the supplied oxygen can be continuously changed, which is convenient for the discharged oxygen to act on the materials evenly, so as to achieve better effects in improving the fermentation efficiency and product quality.
[0014] Through the cooperation among the tank body, the tank cover, the sensor integration box, the feeding hopper, the stirring unit and the auxiliary unit, during the rotation of the cavity block, through the transmission of the insertion rod, the sleeve can be rotated. Since the sleeve is slidably connected with the reciprocating lead screw, the sleeve, the convex block, the bracket and the toothed bar can move up and down reciprocally. During this period, the toothed bar can meshingly drive the gear, so that the gear and the stirring pipe rotate intermittently clockwise and counterclockwise. In this process, the uniformity of the oxygen acting on the materials can be further improved.
[0015] Through the cooperation among the tank body, the tank cover, the sensor integration box, the feeding hopper, the stirring unit and the protection unit, during the injection of pressurized oxygen into the stirring pipe, when the injection pressure is greater than the acting force exerted by the compression spring on the attaching plate, a gap is generated between the attaching plate and the circular ring for the oxygen to pass through and be discharged from the air outlet holes. When the oxygen supply stops, the compression spring quickly rebounds, and the attaching plate will fit and press tightly against the circular ring, which can prevent the materials from entering the inside of the cavity block, and can greatly reduce the maintenance frequency of the internal structural parts of the cavity block, facilitating the long-term and stable operation of the equipment.
[0016] Through the cooperation among the tank body, the tank cover, the sensor integration box, the feeding hopper, the stirring unit and the efficiency enhancing unit, during the process of starting the motor to make the stirring pipe stir the materials inside the tank body, the spiral sheet will rotate together with the circular pipe. Since the spiral sheet is attached to the inner wall of the vertical cylinder, it can transport the materials at the lower part inside the tank body upward, and part of the materials will freely fall from the top end of the vertical cylinder. In addition to making a one-way rotational movement, the materials can also make an up-and-down reciprocating movement, thereby improving the stirring effect on the materials.
[0017] Through the cooperation among the tank body, the tank cover, the sensor integration box, the feeding hopper, the stirring unit and the cleaning unit, after the materials inside the tank body are mixed and fermented and discharged from the tank body, the user starts the motor again. During this process, a pair of groove plates can rotate around the circular tube as the center, and the scraping plates installed inside the groove plates can scrape the inner wall of the tank body, so that the residual materials on the inner wall of the tank body gather and are discharged downward, which can greatly reduce the residual amount of materials on the inner wall of the tank body and is conducive to efficiently carrying out subsequent cleaning operations.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.
[0027] Please refer to Figures 1-6 , the present utility model provides a technical solution: a fermentation device based on biological detection, including: a tank body 1, a tank cover 2 is installed at the top of the tank body 1, a sensor integration box 3 is installed on one side of the upper surface of the tank cover 2, a feeding hopper 4 is fixedly connected to the other side of the upper surface of the tank cover 2, and a stirring unit is arranged below the tank cover 2. The stirring unit includes: a circular tube 5, the circular tube 5 is rotatably connected to the inner wall of the tank cover 2, a disc 6 is fixedly sleeved on the outer wall above the circular tube 5, a toothed ring 7 is fixedly connected to the upper surface of the disc 6, a toothed column 8 is meshed and connected above the toothed ring 7, a rotating rod 9 is fixedly connected to the inner wall of the toothed column 8, a housing 12 is rotatably connected to the outer wall of the rotating rod 9, a motor 10 is installed on the side wall of the housing 12, an output shaft of the motor 10 is fixedly connected to the rotating rod 9, a vertical pipe 11 is rotatably connected to the top of the circular tube 5, a valve 13 is fixedly connected to the top of the vertical pipe 11, a connecting pipe 14 is fixedly connected to the top of the valve 13, a cavity block 15 is fixedly connected to the bottom of the circular tube 5, stirring pipes 16 are rotatably connected to both sides of the cavity block 15, and a plurality of air outlet holes 17 are uniformly formed in the outer wall of the stirring pipes 16.
[0028] In the specific implementation process, it is worth particularly pointing out that the tank body 1 is the tank body structure in the fermentation equipment based on biological detection. An outlet is provided at the bottom end of the tank body 1. The tank cover 2 is connected to the tank body 1 through fastening screws. Rotating the fastening screws can realize the installation and disassembly of the tank cover 2. The sensor integration box 3 is internally provided with a variety of biological sensors or detection modules, which can monitor key biological parameters such as the concentration of microorganisms, the content of metabolites, and the enzyme activity in the fermentation broth in real time. These biological detection technologies include but are not limited to optical detection, electrochemical detection, biochip technology, etc., and have the characteristics of high sensitivity, high selectivity, and real-time performance. The inside of the feeding hopper 4 is communicated with the inside of the tank body 1. An activity baffle is provided at the top end of the feeding hopper 4. The circular tube 5 is rotatably connected to the tank cover 2 through a sealing bearing. The rotating rod 9 is rotatably connected to the housing 12 through a ball bearing. The bottom end of the housing 12 is fixedly connected to the tank cover 2. The housing of the motor 10 is fixedly connected to the housing 12. The motor 10 is a servo motor (the specific model is not limited, as long as it meets the usage requirements), and its power cord is connected to an external power supply device to provide the electric energy required for the operation of the motor 10. The riser 11 is fixedly connected to the circular tube 5 through a sealing bearing. The outer wall of the riser 11 is fixedly connected to the housing 12. The air inlet and outlet of the valve 13 are respectively communicated with the connecting pipe 14 and the riser 11. The end of the connecting pipe 14 away from the valve 13 is connected to an external oxygen supply device. The cavity block 15 is communicated with the inside of the circular tube 5. The stirring pipe 16 is rotatably connected to the cavity block 15 through a sealing bearing.
[0029] Furthermore, a pair of one-way valves 36 are fixedly connected to the upper surface of the tank cover 2.
[0030] In the specific implementation process, it is worth particularly pointing out that the one-way valve 36 is mainly composed of components such as a valve body, a valve core, and a spring. Its working principle is to allow the fluid to conduct in the forward direction and cut off in the reverse direction. The one-way valve 36 allows the gas inside the tank body 1 to be discharged, but the outside air cannot enter the inside of the tank body 1 through it. In this way, it can not only prevent the pressure inside the tank body 1 from being too high, but also facilitate the smooth injection of oxygen into the inside of the tank body 1 to contact the materials. In addition, a hose is installed at the air outlet of the one-way valve 36. Through the conduction of the hose, the discharged gas can be discharged into a gas treatment device or discharged to a distance.
[0031] Further, an auxiliary unit is provided inside the cavity block 15. The auxiliary unit includes: a reciprocating lead screw 18, which is vertically located inside the cavity block 15. The reciprocating lead screw 18 is rotationally connected to the cavity block 15 through a sealed bearing. The bottom end of the reciprocating lead screw 18 is fixedly connected to the inner bottom end of the tank body 1. A sleeve 19 is slidably connected to the outer wall of the reciprocating lead screw 18. On both sides of the outer wall of the sleeve 19, there are fixedly connected convex blocks 20. An insertion rod 21 is inserted into the upper surface of the convex block 20. The top end of the insertion rod 21 is fixedly connected to the cavity block 15. On the side of the convex block 20 away from the sleeve 19, there is a gear 22. The inner wall of the gear 22 is fixedly connected to the stirring pipe 16. The rear side of the gear 22 is meshed with a toothed bar 23. The toothed bar 23 is fixedly connected to the convex block 20 through a bracket 24.
[0032] In the specific implementation process, it is particularly worth noting that the insertion rod 21 penetrates through the convex block 20, and the outer wall of the insertion rod 21 has a clearance fit with the penetration surface of the convex block 20. During the rotation of the cavity block 15, through the transmission of the insertion rod 21, the sleeve 19 can be rotated. Since the sleeve 19 is slidably connected to the reciprocating lead screw 18, the sleeve 19, the convex block 20, the bracket 24, and the toothed bar 23 can perform up and down reciprocating movements. During this period, the toothed bar 23 can engage and drive the gear 22, causing the gear 22 and the stirring pipe 16 to rotate intermittently clockwise and counterclockwise, which can further improve the uniformity of the oxygen acting on the material during this process.
[0033] Further, a protection unit is provided inside the stirring pipe 16. The protection unit includes: a circular ring 25, which is fixedly connected to the inner wall of the stirring pipe 16. A patch plate 26 is attached to the side of the circular ring 25 close to the air outlet hole 17. On the surface of the patch plate 26 close to the circular ring 25, there are fixedly connected a pair of cross bars 27. The cross bars 27 penetrate through the circular ring 25. A gasket 28 is fixedly sleeved on the outer wall of the cross bars 27. A compression spring 29 is fixedly connected between the gasket 28 and the circular ring 25.
[0034] In the specific implementation process, it is particularly worth noting that the outer wall of the cross bar 27 has a clearance fit with the penetration surface of the circular ring 25. Clearance fit means a fit with a clearance (including the minimum clearance equal to zero). When injecting pressurized oxygen into the stirring pipe 16, when the injection pressure is greater than the force exerted by the compression spring 29 on the patch plate 26, a gap is generated between the patch plate 26 and the circular ring 25 for the oxygen to pass through and be discharged from the air outlet hole 17. When the oxygen supply stops, the compression spring 29 quickly rebounds, and the patch plate 26 will fit and press tightly against the circular ring 25, which can prevent the material from entering the inside of the cavity block 15 and can greatly reduce the maintenance frequency of the internal structural parts of the cavity block 15.
[0035] Further, a cleaning facilitation unit is provided at the end of the stirring tube 16 away from the cavity block 15. The cleaning facilitation unit includes a groove plate 30 fixedly connected to the end of the stirring tube 16 away from the cavity block 15. A scraping plate 31 is inserted into the interior of the groove plate 30. Bolts 32 are threadedly connected to both the front and rear sides of the groove plate 30. The bolts 32 penetrate a part of the groove plate 30 and abut against the scraping plate 31, and the scraping plate 31 abuts against the inner wall of the tank body 1.
[0036] In the specific implementation process, it is particularly worth noting that the scraping plate 31 is made of fluororubber material and has a certain flexibility. The scraping plate 31 is inserted and connected to the groove plate 30. The scraping plate 31 can be replaced by rotating the bolt 32, and it can ensure that the scraping plate 31 effectively abuts against the inner wall of the tank body 1. After the material in the tank body 1 is mixed and fermented and discharged from the tank body 1, the user starts the motor 10 again. During this process, a pair of groove plates 30 can rotate around the circular tube 5 as the center. The scraping plate 31 installed in the groove plate 30 can scrape the inner wall of the tank body 1, so that the residual material on the inner wall of the tank body 1 gathers and discharges downward, which can greatly reduce the residual amount of material on the inner wall of the tank body 1.
[0037] Further, an efficiency improvement unit is provided on the outer side of the circular tube 5. The efficiency improvement unit includes: a pair of vertical rods 33 fixedly connected to the inner top end of the tank cover 2. A vertical cylinder 34 is fixedly connected to the bottom end of the vertical rod 33. A spiral sheet 35 is attached to the inner wall of the vertical cylinder 34, and the spiral sheet 35 is fixedly connected to the circular tube 5.
[0038] In the specific implementation process, it is particularly worth noting that in order to facilitate understanding that the rotation of the spiral sheet 35 can lift the material, it is necessary to give an example of the working principle of the spiral sheet 35. When the spiral sheet 35 rotates and fits with the inner wall of the vertical cylinder 34, the principle of lifting the material is the same as that of the feeding principle of a screw conveyor. During the period when the motor is started and the stirring tube 16 stirs the material inside the tank body 1, the spiral sheet 35 will rotate together with the circular tube 5. Because the spiral sheet 35 fits with the inner wall of the vertical cylinder 34, it can transport some of the material below the tank body 1 upward, and some of the material will freely fall from the top end of the vertical cylinder 34. In addition to making a one-way rotational movement, the material can also perform an up-and-down reciprocating movement.
[0039] Working principle:
[0040] Oxygen supply operation for the material inside the tank:
[0041] First, the user inputs an appropriate amount of materials to be mixed and fermented into the interior of the tank body 1 through the feeding hopper 4, closes the top cover of the feeding hopper 4, and starts the motor 10 to enable the two stirring pipes 16 to mix and stir the materials inside the tank body. During this period, by opening and closing the valve 13, oxygen is injected into the interior of the riser pipe 11, the circular pipe 5, the cavity block 15, and the stirring pipe 16 through the connecting pipe 14. After the oxygen enters the interior of the stirring pipe 16, it will be discharged from the air outlet holes 17 and act on the materials. In this process, since the two stirring pipes 16 continuously revolve around the circular pipe 5, the oxygen supply position can be continuously changed, facilitating the uniform action of the discharged oxygen on the materials, thereby achieving better effects in improving the fermentation efficiency and product quality. During the rotation of the cavity block 15, through the transmission of the insertion rod 21, the sleeve 19 can be rotated. Since the sleeve 19 is slidably connected to the reciprocating lead screw 18, the sleeve 19, the convex block 20, the support 24, and the tooth bar 23 can perform up-and-down reciprocating movements. During this period, the tooth bar 23 can engage and drive the gear 22, causing the gear 22 and the stirring pipe 16 to rotate intermittently clockwise and counterclockwise. In this process, the uniformity of the oxygen acting on the materials can be further improved;
[0042] Operation to enhance the stirring of the materials inside the tank body:
[0043] During the period when the motor is started to make the stirring pipe 16 stir the materials inside the tank body 1, the spiral blade 35 will rotate together with the circular pipe 5. Since the spiral blade 35 is in contact with the inner wall of the vertical cylinder 34, the materials at the lower part inside the tank body 1 can be transported upward, and some materials will freely fall from the top of the vertical cylinder 34. In addition to making a one-way rotational movement, the materials can also perform up-and-down reciprocating movements, thereby enhancing the stirring effect on the materials;
[0044] Pre-operation before cleaning the interior of the tank body:
[0045] After the materials inside the tank body 1 are mixed and fermented and discharged from the tank body 1, the user starts the motor 10 again. During this process, a pair of groove plates 30 can rotate around the circular pipe 5 as the center, and the scraping plates 31 installed inside the groove plates 30 can scrape the inner wall of the tank body 1, causing the residual materials on the inner wall of the tank body 1 to gather and be discharged downward, which can greatly reduce the residual amount of materials on the inner wall of the tank body 1 and is conducive to the efficient development of subsequent cleaning operations.
[0046] It should be noted that whether the motor 10 in the equipment runs to stir the materials inside the tank body 1 and whether oxygen supply operations need to be performed on the materials inside the tank body 1 need to be judged according to the data collected by the sensor integration box 3.
[0047] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
