Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, and in particular to a probiotic solid fermentation incubator. Background Technology

[0002] Probiotics, as live microorganisms beneficial to the health of the host, have wide applications in food, medicine, and agriculture. Industrial production of probiotics typically employs fermentation technology, among which solid-state fermentation has become an important cultivation method due to its advantages such as low energy consumption, high product yield, and low risk of contamination.

[0003] In solid-state fermentation, to ensure the uniform and stable growth of probiotics, it is necessary to control conditions such as temperature, humidity, and oxygen concentration of the culture medium. The uniform distribution of these conditions highly depends on the effective agitation and mixing of the fermentation materials. As the core equipment for achieving this process, the material mixing structure inside the solid-state fermentation incubator is of paramount importance.

[0004] However, existing solid-state fermentation incubators typically use a single agitator or stirring arm to agitate the materials. This design has significant drawbacks. During agitation, due to the inherent viscosity of the materials, some tend to adhere to the inner wall of the tank, creating dead zones where the material cannot be effectively agitated. Simultaneously, the material at the bottom of the tank easily accumulates and compacts due to gravity, making it difficult for the agitator alone to fully agitate it, resulting in clumping. This uneven mixing directly leads to low mass and heat transfer efficiency during fermentation, severely impacting the growth activity of probiotics and the quality and uniformity of the final product.

[0005] Therefore, this invention proposes a probiotic solid-state fermentation incubator to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems existing in the probiotic solid fermentation incubator, such as the simple turning structure leading to the material easily adhering to the tank wall or accumulating and clumping at the bottom of the tank, resulting in uneven mixing and thus affecting the fermentation efficiency, this utility model aims to provide a probiotic solid fermentation incubator with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a probiotic solid fermentation incubator, including an outer tank of a fermentation tank, a cover plate assembly covering the top of the outer tank of the fermentation tank, an inner tank of fermentation tank detachably disposed inside the outer tank of the fermentation tank, and a turning assembly disposed inside the inner tank of the fermentation tank.

[0008] The cover assembly includes an upper cover and a motor fixedly installed on the upper cover; the flipping assembly includes a rotating shaft vertically arranged in the center of the fermentation tank, and the top end of the rotating shaft is connected to the output end of the motor through a transmission mechanism consisting of a drive rod, a connecting column and a transition rod connected in sequence.

[0009] The core structure of this utility model is that a spiral scraper is fixedly connected to the outer periphery of the rotating shaft, the outer edge of the spiral scraper is set to fit against the inner wall of the fermentation tank, and a turning plate is fixedly connected to the bottom of the rotating shaft. The spiral scraper and the turning plate rotate synchronously under the drive of the rotating shaft, thereby realizing three-dimensional turning and mixing of the material in the fermentation tank.

[0010] Preferably, the flipping assembly further includes a sliding ring, which is disposed around the rotating shaft and fixedly connected to the inner edge of the spiral scraper. This structure is used to provide radial support for the spiral scraper, enhance its structural stability during rotation, and ensure its fit with the tank wall.

[0011] Preferably, the upper cover is provided with a feed inlet and a ventilation groove. The feed inlet is used to conveniently add or replenish fermentation materials to the fermentation tank, and the ventilation groove is used to maintain the necessary gas exchange in the fermentation environment during the fermentation process.

[0012] Preferably, in order to enable the rapid installation and disassembly of the fermentation inner tank, a connecting slot is provided on the upper inner wall of the outer tank of the fermentation tank, and a limiting block is correspondingly provided on the outer wall of the fermentation inner tank to engage with the connecting slot. This structure makes the discharge and cleaning work after fermentation extremely convenient.

[0013] Preferably, the probiotic solid-state fermentation incubator further includes a fixing component for locking the cover assembly to the outer tank of the fermentation tank, ensuring the airtightness of the fermentation process. Specifically, the fixing component includes a fixing seat fixed to the outer side of the outer tank of the fermentation tank, a retaining plate provided at the bottom outer edge of the upper cover, and a latching block rotatably connected to the fixing seat for fastening the retaining plate. Furthermore, the fixing component also includes a push rod linked to the latching block and a plate buckle for driving the push rod to move. By operating the plate buckle, the cover assembly can be quickly locked or unlocked, making the operation simple and effortless.

[0014] Preferably, in order to ensure that the equipment can be placed stably, the bottom of the outer tank of the fermentation tank is fixedly connected with multiple support legs, and the bottom end of each support leg is connected with a support foot to increase the contact area with the ground and improve the overall stability.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem in existing solid fermentation tanks where only a single stirring paddle causes materials to easily adhere to the tank wall or accumulate and clump at the bottom, resulting in uneven mixing and insufficient fermentation. It achieves the technical effect of omnidirectional, three-dimensional, and uniform turning of materials, significantly improving fermentation efficiency and product uniformity. By setting a rotating shaft inside the fermentation tank and simultaneously fixing a spiral scraper for scraping the material on the tank wall and a turning plate for turning the material at the bottom of the tank on the rotating shaft, this invention achieves the technical effect of omnidirectional, three-dimensional, and uniform turning of materials.

[0016] 2. This utility model, by adopting a detachable structure in which the inner fermentation tank and the outer fermentation tank cooperate, and by using limiting blocks and connecting slots to achieve quick positioning and fixation, solves the problems of difficult material discharge after fermentation and tedious and time-consuming internal cleaning of traditional integrated fermentation tanks. It achieves the technical effects of simplifying the operation process, improving equipment turnover rate and cleaning efficiency.

[0017] 3. This utility model solves the problems of cumbersome operation and uneven locking force of traditional bolt or clamp fixing methods by setting a lever-type fixing component consisting of a plate buckle, a push rod and a locking block. It achieves the technical effect of quickly, effortlessly and reliably locking the cover plate and ensuring a stable and sealed fermentation environment. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 4 This utility model provides a probiotic solid fermentation incubator, which aims to solve the problems of insufficient turning and uneven mixing of solid fermentation materials in the prior art.

[0022] like Figure 1 As shown, the basic frame of the probiotic solid fermentation incubator includes an outer tank 2 of the fermentation tank and a cover plate assembly 5 covering the top of the outer tank 2 of the fermentation tank. The bottom of the outer tank 2 of the fermentation tank is fixedly connected with multiple support legs 1 for stable support. The bottom end of each support leg 1 is connected with a support foot 3 for increasing the contact area. Reference Figure 1 , Figure 2 and Figure 4 The fermenter outer tank 2 is detachably provided with an inner fermentation tank 605 for containing materials. The inner fermentation tank 605 is provided with a turning component 6 for turning the materials. The cover assembly 5 includes an upper cover 505 and a motor 504 fixedly installed on the upper cover 505, which serves as a power source. The turning component 6 includes a rotating shaft 602, which is vertically arranged at the center of the inner fermentation tank 605. Its top end passes through the inner fermentation tank 605 and is connected to the cover assembly 5 for transmission, so as to receive power from the motor 504. The power transmission structure is as follows: the output end of the motor 504 is fixedly connected to the drive rod 506, the other end of the drive rod 506 is slidably engaged with the connecting column 503 and linked together, the other end of the connecting column 503 is connected to the adapter rod 507, and the end of the adapter rod 507 is fixedly connected to the top end of the rotating shaft 602, thereby transmitting the rotational motion of the motor 504 to the rotating shaft 602. The core agitation structure of the agitation component 6 is as follows: a spiral scraper 603 extending in a spiral shape is fixedly connected to the outer periphery of the rotating shaft 602. The outer edge of the spiral scraper 603 is set to fit against the inner wall of the fermentation tank 605 and is used to scrape and turn over the material attached to the inner wall and the upper layer when rotating. A flipping plate 604 is fixedly connected to the bottom of the rotating shaft 602. The flipping plate 604 is used to perform bottom-scooping agitation on the material at the bottom of the fermentation tank 605.

[0023] To achieve the aforementioned goal of uniform turning, the core of the technical solution in this embodiment lies in the specific structural combination of the turning component 6 and its cooperation with the fermentation inner tank 605. Please refer to the following for details. Figure 4 The core structure will be described in detail below: The flipping assembly 6 also includes a sliding ring 601, which is encircled on the rotating shaft 602 and its outer edge is fixedly connected to the inner edge of the spiral scraper 603. The function of the sliding ring 601 is to provide radial support for the spiral scraper 603, ensuring that the spiral scraper 603 maintains a stable shape and distance from the tank wall during rotation. In the assembled state, both the spiral scraper 603 and the flipping plate 604 are fixed on the rotating shaft 602. When the motor 504 drives the rotating shaft 602 to rotate, the spiral scraper 603 scrapes around the inner wall of the fermentation tank 605, scraping away the adhering material and pushing it towards the central area. At the same time, the flipping plate 604 rotates synchronously at the bottom of the tank, flipping the material at the bottom upwards. The combined motion of the two ensures that the material in the tank can be mixed in a three-dimensional manner from top to bottom and from inside to outside, effectively avoiding fermentation dead corners and material clumping.

[0024] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, for ease of material addition and gas exchange, please refer to... Figure 2 The upper cover 505 is provided with a feed inlet 501 and a ventilation groove 502. The feed inlet 501 is used to put or replenish fermentation materials into the fermentation tank 605, and the ventilation groove 502 is used to maintain the gas circulation between the inside of the fermentation tank 605 and the external environment. As another preferred embodiment, to achieve rapid positioning and installation of the fermentation inner tank 605, please refer to... Figure 3 and Figure 4 The upper inner wall of the outer tank 2 of the fermentation tank is provided with a connecting slot 7, and the outer wall of the inner fermentation tank 605 is provided with a limiting block 8 that engages with the connecting slot 7. During installation, the inner fermentation tank 605 can be fixed by simply aligning the limiting block 8 and inserting it into the connecting slot 7. As another preferred embodiment, to ensure airtightness during the fermentation process, please refer to... Figure 1 and Figure 3 The incubator also includes a fixing component 4 for locking the cover assembly 5 to the outer tank 2 of the fermenter. The fixing component 4 includes a fixing seat 401 fixed to the outside of the outer tank 2 of the fermenter. An annular retaining plate 508 is provided on the bottom outer edge of the upper cover 505. A retaining block 403 is rotatably connected to the fixing seat 401. The retaining block 403 is used to retain the retaining plate 508, thereby pressing the cover assembly 5 downward onto the outer tank 2 of the fermenter. Furthermore, in order to make the locking operation more convenient and effortless, the fixing component 4 also includes a push rod 402 that is linked to the latching block 403 and a plate buckle 404 for driving the push rod 402. By operating the plate buckle 404, the push rod 402 can be driven to make the latching block 403 complete the latching or loosening of the card plate 508.

[0025] The working principle of this probiotic solid-state fermentation incubator is as follows: During fermentation, the fermentation inner tank 605 with the turning component 6 is first positioned and installed by inserting the limiting block 8 on its outer wall into the connecting slot 7 of the outer tank 2. Then, the material is put into the fermentation inner tank 605 through the inlet 501 on the cover assembly 5. After that, the cover assembly 5 is closed, and the plate buckle 404 of the fixing component 4 is operated to drive the push rod 402, which causes the buckle block 403 to rotate and fasten onto the clamping plate 508 of the cover assembly 5, thereby firmly locking the cover assembly 5 to the outer tank 2 of the fermentation tank and forming a stable fermentation environment.

[0026] When the fermentation process starts, the motor 504 installed on the top cover 505 is started. Its power is transmitted to the rotating shaft 602 inside the fermentation tank 605 through the transmission mechanism composed of the drive rod 506, connecting column 503 and adapter rod 507, driving the rotating shaft 602 to rotate. As the rotating shaft 602 rotates, the spiral scraper 603 fixed to its outer periphery moves synchronously along the inner wall of the fermentation tank 605, scraping off the material adhering to the tank wall and turning it towards the center area. At the same time, the turning plate 604 fixed to the bottom of the rotating shaft 602 performs a synchronous bottom-scooping turning at the bottom of the tank, lifting the material settled at the bottom upwards. The synergistic effect of the spiral scraper 603 and the turning plate 604 enables the material in the entire fermentation tank 605 to achieve all-round three-dimensional mixing from top to bottom and from the edge to the center, effectively solving the problem of low fermentation efficiency caused by material accumulation and uneven mixing in the prior art. Throughout the process, the venting groove 502 maintains gas exchange.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
