Description

Technical Field

[0001] The present invention relates to the technical field of food fermentation equipment, in particular to a fermentation equipment for processing pet food and a use method thereof. Background Art

[0002] Fermentation is a technology that uses the metabolic activities of microorganisms to change the characteristics of food ingredients. It is often used in the field of pet food processing. It uses specific microorganisms, such as lactic acid bacteria and yeast, to decompose and transform carbohydrates, proteins and other components in pet food ingredients under suitable temperature, humidity and oxygen conditions, thereby increasing the nutritional value of pet food.

[0003] For example, the "A Pet Food Processing and Fermentation Equipment" with publication number CN115491287B includes a frame and a crushing box, a mixing tank and a fermentation tank arranged on the frame in sequence from top to bottom; the crushing box is arranged at the top center of the mixing tank, and a crushing mechanism for crushing the fermented material is provided in the crushing box; a stirring mechanism for stirring the fermented material is provided in the mixing tank; a plurality of flattening plates are provided in the fermentation tank along the axial direction, and the diameter of the flattening plates is the same as the inner diameter of the fermentation tank, and the flattening plates can rotate with their diameter as the axis, and a plurality of placement holes are provided on the flattening plates, which are interconnected, and a sealing plate that can move along the axial direction of the placement hole is provided under each placement hole.

[0004] However, in the prior art, when inoculating microorganisms, the fermentation tank needs to be opened before the microorganisms can be injected. During this process, the environment inside the fermentation tank will be connected to the external environment, which can easily cause microorganisms in the environment to enter the fermentation tank and contaminate the raw materials. Moreover, these microorganisms will also affect the activity of the microorganisms used for fermentation after subsequent contact with the microorganisms used for fermentation, which can easily lead to the final raw materials not being fully fermented. In addition, this inoculation method will cause the microorganisms to concentrate on the top of the raw materials, and sufficient stirring is required to allow the raw materials to fully contact with the microorganisms. During the stirring process, there will be a problem that the raw materials may be easily damaged if the stirring degree is too high. When the stirring degree is insufficient, the raw materials may not be fully contacted with the microorganisms, making it difficult to ensure the fermentation quality. Summary of the Invention

[0020] A method for using a fermentation device for processing pet food comprises the following steps:

[0021] S1. Open the cover and place the processed pet food raw materials into the fermentation tank body. After placing the raw materials, start the inoculation mechanism to inoculate the microorganisms. During the inoculation process, simultaneously start the stirring mechanism to stir the raw materials;

[0022] S2. Place the inoculator into the hollow tube and connect the hose to a device that provides liquid microorganisms from the outside. Then, pressurize air into the hollow tube and use the air to push the inoculator along the hollow tube. When the inoculator moves to the inoculation node, stop pressing air and start the electric push rod to connect the cavity with the inoculation node.

[0023] S3. After the liquid microorganisms enter the fermentation tank body, they are fully stirred by the stirring mechanism to ensure full contact between the raw materials and the microorganisms. Then, a suitable temperature is selected according to the microbial strain for fermentation. During the fermentation process, the stirring mechanism is started regularly to stir the raw materials compared with the existing technology.

[0024] The beneficial effects of the present invention are:

[0025] 1. In the present invention, a spiral hollow tube is provided so that the hollow tube can completely cover the entire fermentation tank body. When inoculating, the inoculator moves along the hollow tube, passing through the inoculation nodes in sequence, and injects the microorganisms for fermentation into the fermentation tank body at the inoculation nodes. The inoculation nodes surround the raw materials, ensuring that the microorganisms are in full contact with the raw materials at various positions in the fermentation tank body, thereby solving the problem of uneven mixing when inoculating the microorganisms. Compared with the traditional inoculation method, the problem of microorganisms concentrating in a certain place in the raw materials can be avoided. In addition, the stirring rod in the stirring mechanism can stir the raw materials in the vertical direction, fully mixing the injected microorganisms with the raw materials, allowing the microorganisms to be dispersed to all parts of the raw materials, and ensuring that the raw materials are fermented more fully.

[0026] 2. In the present invention, the stirring rod is rotatably mounted on the positioning cylinder, which can ensure its own structural stability, and is smoother when stirring the raw materials without increasing the load of the servo motor. In addition, during use, the stirring rod rotates in the vertical direction, which can achieve the purpose of stirring the raw materials, and can mix the raw materials below with the raw materials above. In addition, the stirring rod is also an arc-shaped structure, which reduces its own volume while ensuring the contact range with the raw materials, preventing the situation where some raw materials cannot be stirred. When used in conjunction with the turning rod at the bottom, the raw materials at the bottom can be turned to the top, so that all the raw materials can fully contact with oxygen.

[0027] 3. In the present invention, a blocking block for blocking the cavity is provided inside the inoculator. When in use, the inoculator is connected to the external feeding equipment through a hose, and the microorganisms used for inoculation enter the cavity through the hose and wait for inoculation. When the inoculator moves to the inoculation node, the electric push rod pushes the blocking block, pushes out the movable block in the docking block, and uses the movable block to synchronously push open the blocking plate, so that the microorganisms can enter the fermentation tank body and contact the raw materials. This method does not need to open the cover during operation, thereby ensuring that the environment inside the fermentation tank body will not be damaged. At the same time, it can also ensure that the microorganisms can fully contact the raw materials at various positions, thereby ensuring the fermentation efficiency and the quality of the final product.

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] Example 1: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 11 The present invention discloses a fermentation device for processing pet food and a method for using the same, comprising a fermentation tank body 1, an inoculation mechanism 4 for inoculating microorganisms fixedly mounted on the tank wall of the fermentation tank body 1, a stirring mechanism 3 for stirring the raw materials rotatably mounted on the inner side of the fermentation tank body 1, and a cover plate 2 movably mounted on the top of the fermentation tank body 1;

[0042] The inoculation mechanism 4 includes a hollow tube 41 fixedly mounted in a spiral shape on the outer wall of the fermentation tank body 1. An inoculator 43 is slidably connected to the interior of the hollow tube 41. An insulation board 42 is fixedly mounted at the junction of the fermentation tank body 1 and the hollow tube 41. Inoculation nodes 45 are evenly spaced on the insulation board 42. The inoculator 43 moves along the hollow tube 41 and passes through multiple inoculation nodes 45 in sequence to inoculate microorganisms into the raw material.

[0043] The stirring mechanism 3 includes a positioning cylinder 36 arranged on the axis of the fermentation tank body 1 and a stirring rod 37 rotatably mounted on the edge thereof. A transmission rod 32 is rotatably mounted inside the positioning cylinder 36. A transmission block 314 is fixedly mounted on the rod body of the transmission rod 32. The stirring rod 37 is located at the edge of the transmission rod 32.

[0044] A triangular notch 315 is provided at the bottom of the edge of the transmission block 314, and a receiving groove 316 is provided at the top of the triangular notch 315. A limit block 34 is fixedly installed at the bottom of the transmission block 314 below the triangular notch 315, and the shape of the limit block 34 is adapted to the shape of the triangular notch 315.

[0045] In this embodiment, the food to be processed is washed, crushed, and steamed before being poured into the fermentation tank body 1 through the cover plate 2. Then, liquid microorganisms are injected into the fermentation tank body 1 using the inoculation mechanism 4. During the inoculation process, the stirring mechanism 3 is simultaneously activated to stir the raw materials and microorganisms, allowing the microorganisms and the raw materials to be fully mixed together. Then, a suitable temperature is selected according to the microbial strain for fermentation. During the fermentation process, the stirring mechanism 3 is periodically activated to stir the raw materials to ensure that the microorganisms can obtain sufficient oxygen and to prevent the precipitation of nutrients.

[0046] The hollow tube 41 in the inoculation mechanism 4 is spirally mounted on the body of the fermentation tank 1. During inoculation, the inoculator 43 carries the liquid microorganisms and moves along the hollow tube 41, passing through the inoculation nodes 45 provided on the fermentation tank 1 in sequence. When the inoculator 43 reaches the inoculation nodes 45, the liquid microorganisms are injected into the fermentation tank 1 to contact the raw materials and complete the inoculation. An insulation plate 42 is provided at the junction of the hollow tube 41 and the fermentation tank 1 to prevent heat leakage.

[0047] During the inoculation process, the transmission rod 32 in the stirring mechanism 3 will also rotate synchronously. The transmission rod 32 drives all the stirring rods 37 to rotate in the vertical direction in turn through the transmission block 314, fully stirring the raw materials so that the raw materials are in full contact with the microorganisms, avoiding the situation where the microorganisms gather in one place. The stirring rod 37 is installed on the positioning cylinder 36, and its own arc structure is adapted to the fermentation tank body 1, which not only ensures its own structural stability, but also does not encounter too much resistance during the rotation process.

[0048] Example 2: According to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, a servo motor 31 and a coupling on its output shaft are fixedly mounted on the top of the fermentation tank body 1. The servo motor 31 is fixedly connected to a transmission rod 32 via a coupling. The bottom of the transmission rod 32 is rotatably connected to a hollow housing 33. The bottom of the hollow housing 33 is fixedly connected to a support rod 311. The bottom of the support rod 311 is fixedly connected to the fermentation tank body 1.

[0049] A triangular notch 315 is provided at the bottom of the edge of the transmission block 314, and a receiving groove 316 is provided at the top of the triangular notch 315. A limit block 34 is fixedly installed at the bottom of the transmission block 314 below the triangular notch 315, and the shape of the limit block 34 is adapted to the shape of the triangular notch 315.

[0050] An arc-shaped plate 312 is fixedly mounted on the end of the stirring rod 37 close to the transmission block 314 . Both ends of the arc-shaped plate 312 are fixedly mounted with protrusions 313 . The protrusions 313 overlap the lower surface of the transmission block 314 .

[0051] In this embodiment, the servo motor 31 is used to drive the transmission rod 32. The transmission rod 32 rotates, driving the transmission block 314. During the rotation of the transmission block 314, the limit block 34 pushes the protrusion 313 into the triangular notch 315. Since the protrusion 313 is installed at the end of the arc-shaped plate 312, when one protrusion 313 enters the triangular notch 315, the arc-shaped plate 312 rotates, causing the other protrusion 313 to move below the limit block 34.

[0052] Then the upper protrusion 313 will enter the receiving groove 316. At this time, due to the obstruction of the receiving groove 316, the upper protrusion 313 cannot move. At this time, the lower protrusion 313 will continue to move until the lower protrusion 313 moves to the other end of the triangular notch 315. At this time, the arc plate 312 will be parallel to the side of the triangular notch 315 again, and the upper protrusion 313 can be moved out of the receiving groove 316. When the subsequent transmission block 314 continues to rotate, the protrusion 313 will move out of the triangular notch 315. This process will cause the entire stirring rod 37 to complete a flip, and the support rod 311 and the hollow shell 33 can determine the position of the transmission rod 32.

[0053] Example 3: According to Figure 3 and Figure 4 As shown, a support frame 310 is fixedly installed inside the hollow shell 33, a gear shaft 39 is fixedly installed on the top of the support frame 310, a bevel gear 38 is fixedly installed on the end of the transmission rod 32, the gear shaft 39 is meshed with the bevel gear 38, and a tipping rod 35 is fixedly installed on the end of the gear shaft 39, and the tipping rod 35 is located at the bottom of the fermentation tank body 1.

[0054] In this embodiment, during the rotation of the transmission rod 32, the gear shaft 39 will be engaged through the bevel gear 38 to drive the turning rod 35 set at the end of the gear shaft 39. The turning rod 35 is at the bottom of the fermentation tank body 1. During its rotation, it can stir the raw materials at the bottom of the fermentation tank body 1 to the top of the tank body, so that the raw materials at the bottom can move to the top and fully contact with oxygen. The presence of the support frame 310 and the hollow shell 33 can ensure the structural stability of the gear shaft 39.

[0055] Example 4: According to Figure 2 、 Figure 8 、 Figure 9 and Figure 10As shown, a docking block 44 is fixedly installed on one side of the inoculator 43, and the docking block 44 is overlapped on the tank body of the fermentation tank main body 1. A first spring telescopic rod 46 is fixedly installed inside the inoculation node 45, and one end of the first spring telescopic rod 46 is slidably connected to a blocking plate 47, which is located at the entrance of the inoculation node 45;

[0056] A guide rail 49 is fixedly mounted on the inner wall of the hollow tube 41. A slider 48 is slidably connected to the inner side of the guide rail 49. The slider 48 is fixedly connected to the edge of the inoculator 43. A partition plate 411 is fixedly connected to one end of the inoculator 43. A hose 412 is fixedly connected to the interior of the inoculator 43. A movable block 414 is slidably mounted inside the docking block 44.

[0057] An electric push rod 410 is fixedly mounted on one side of the partition plate 411. One end of the piston rod of the electric push rod 410 is fixedly connected to a blocking block 413. The blocking block 413 is slidably connected to the interior of the inoculator 43. A cavity 415 is formed inside the inoculator 43.

[0058] A second trapezoidal rod 417 is fixedly installed on one side of the movable block 414, and one end of the blocking block 413 is fixedly connected to the first trapezoidal rod 416. The inclined surface of the first trapezoidal rod 416 is slidingly connected to the inclined surface of the second trapezoidal rod 417. A second spring telescopic rod 418 is fixedly connected between the movable block 414 and the inoculator 43.

[0059] In this embodiment, the docking block 44 on the side of the inoculator 43 is attached to the fermenter body 1, which can ensure the structural stability of the inoculator 43 and prevent the inoculator 43 from shaking in the hollow tube 41. A guide rail 49 is provided on the inner wall of the hollow tube 41 to determine the movement path of the inoculator 43. A slider 48 is provided between the guide rail 49 and the inoculator 43 to reduce friction.

[0060] The shape of the partition plate 411 matches that of the hollow tube 41 and is used to separate the space. During use, air is continuously pressed into the hollow tube 41, and the force of the gas on the partition plate 411 causes the inoculator 43 to move along the hollow tube 41. The inoculator 43 is connected to an external feeding device via a hose 412. Liquid microorganisms are injected into the cavity 415 through the hose 412. Under normal conditions, the movable block 414 blocks the cavity 415.

[0061] As the inoculator 43 moves along the hollow tube 41, it passes through the inoculation node 45 in sequence. A sensor is provided at the inoculation node 45. When the inoculator 43 moves to the inoculation node 45, the air is stopped from being pressed in, and the electric push rod 410 presses the blocking block 413 into the cavity 415. As the blocking block 413 moves, the first trapezoidal rod 416 pushes the second trapezoidal rod 417, so that the movable block 414 moves out of the docking block 44 and pushes the blocking plate 47 into the inoculation node 45. The blocking plate 47 compresses the first spring telescopic rod 46, allowing the liquid microorganisms to pass through the inoculation node 45 and enter the fermentation tank body 1.

[0062] After the inoculation is completed, the electric push rod 410 moves the blocking block 413 out of the cavity 415, and uses the rebound of the second spring telescopic rod 418 to pull the movable block 414 back into the cavity 415. The rebound of the first spring telescopic rod 46 can also synchronously push the blocking plate 47 back to the entrance of the inoculation node 45.

[0063] The method of use and working principle of this device are as follows: After the food to be processed has been cleaned, crushed, and steamed, it is poured into the fermentation tank body 1 through the cover plate 2. Then, liquid microorganisms are injected into the fermentation tank body 1 using the inoculation mechanism 4. The inoculator 43 is connected to the external feeding device through the hose 412. The liquid microorganisms are injected into the cavity 415 through the hose 412. Under normal conditions, the movable block 414 will block the cavity 415.

[0064] During use, air is continuously pressed into the hollow tube 41, and the inoculator 43 is moved along the hollow tube 41 by the thrust of the gas on the partition plate 411. When the inoculator 43 moves to the inoculation node 45, the air is pressed and the electric push rod 410 presses the blocking block 413 into the cavity 415. The first trapezoidal rod 416 pushes the second trapezoidal rod 417 to move the movable block 414 out of the docking block 44 and push the blocking plate 47 into the inoculation node 45, allowing the liquid microorganisms to pass through the inoculation node 45 and enter the fermentation tank body 1.

[0065] After the inoculation is completed, the electric push rod 410 moves the blocking block 413 out of the cavity 415, and uses the rebound of the second spring telescopic rod 418 to pull the movable block 414 back into the cavity 415. The rebound of the first spring telescopic rod 46 can also synchronously push the blocking plate 47 back to the entrance of the inoculation node 45, and then air is injected to push the inoculator 43 to continue moving;

[0066] During the inoculation process, the stirring mechanism 3 is synchronously activated to stir the raw materials and microorganisms. The servo motor 31 drives the transmission rod 32, and the transmission block 314 on the transmission rod 32 pushes the stirring rod 37. As the transmission block 314 rotates, the limit block 34 pushes one protrusion 313 into the triangular notch 315. At this time, the arc plate 312 rotates and moves the other protrusion 313 to the bottom of the limit block 34.

[0067] After the upper protrusion 313 enters the receiving groove 316, it becomes immobile. At this time, the lower protrusion 313 continues to move, thereby flipping the stirring rod 37 and mixing the lower and upper raw materials together. When the lower protrusion 313 moves to the other end of the triangular notch 315, the curved plate 312 becomes parallel to the side of the triangular notch 315 again, and the upper protrusion 313 can be removed from the receiving groove 316.

[0068] Then, a suitable temperature is selected according to the microbial strain for fermentation. During the fermentation process, the stirring mechanism 3 is started regularly to stir the raw materials to ensure that the microorganisms can obtain sufficient oxygen and prevent the precipitation of nutrients.

[0069] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
