Description

Technical Field

[0001] This invention relates to the field of animal feed production technology, specifically a high-efficiency constant-temperature feed fermentation tank device. Background Technology

[0002] In the animal feed production sector, fermented feed is highly dependent on fermentation equipment due to its advantages such as improving nutrient absorption efficiency and inhibiting the growth of harmful bacteria. High-efficiency constant-temperature feed fermentation tanks are one of the core pieces of equipment for achieving large-scale and stable production of fermented feed. These devices typically need to complete key processes such as mixing after raw material pretreatment, temperature control, stirring, aeration, and pH monitoring during fermentation to create a suitable environment for microbial (e.g., yeast) fermentation, ensuring the quality and safety of the final feed product. Currently, widely used fermentation tanks in the industry typically include basic components such as the fermentation tank body, temperature control equipment, stirring equipment, aeration equipment, and pH monitoring equipment. Through the coordinated work of these components, raw materials such as corn and soybean meal are mixed in specific proportions and fermented for a certain period under set temperature, aeration, and other parameters to ultimately produce fermented feed that meets the requirements, supporting the animal feed industry's demand for high-quality fermented products.

[0003] Existing high-efficiency constant-temperature feed fermentation tanks suffer from poor coordination between stirring and heating in practical applications. The stirring equipment is mostly a single rotating shaft or a fixed structure, which easily creates blind spots in the stirring process, resulting in uneven mixing of materials inside the tank. At the same time, the heating equipment mostly uses tank wall heating or single-area heating, making it difficult to achieve precise temperature control in different areas of the tank. Temperature fluctuations often exceed ±3℃, making it impossible to stably maintain the suitable temperature range required for microbial fermentation. Therefore, in view of the above situation, there is an urgent need to develop a high-efficiency constant-temperature feed fermentation tank to overcome the shortcomings in current practical applications. Summary of the Invention

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] 1. Synergistic optimization of feed formulation and preparation process to improve the quality and production stability of fermented feed: A precise ratio of 60% corn, 25% soybean meal, 8% wheat bran, 2% yeast powder, 1% mineral premix, and 5% water is used. The mineral premix is ​​formulated with calcium, phosphorus, and potassium sources in specific proportions, and the yeast powder is selected with a live bacteria count ≥1×10⁻⁶. 9The active brewing yeast powder (CFU / g) is prepared by crushing corn and soybean meal to 1.0-2.0mm during raw material pretreatment to ensure material contact area and flowability. During fermentation, the temperature (30-38℃), stirring speed (30-50r / min), aeration rate (0.5-1.0m³ / (h・m³ material)), and pH value (aeration is stopped when the pH is below 4.0) are precisely controlled, and the temperature fluctuation is maintained at ≤±2℃. This effectively adapts to the yeast fermentation requirements, inhibits the growth of miscellaneous bacteria, and ensures balanced feed nutrition and low miscellaneous bacteria content.

[0044] 2. Integrated mixing and heating design to solve the problem of uneven heating of materials: The drive unit of the mixing equipment drives the mixing shaft to rotate. The cross bracket on the shaft is connected to the support cylinder. The heating equipment is installed in the protective shell on the support cylinder. The step heating module in the heating equipment is connected to the temperature control equipment. It can independently control the temperature according to the temperature feedback of different areas in the tank. Combined with the rotation of the mixing shaft, it realizes "dynamic mixing + zoned precise heating", avoiding local overheating or underheating, ensuring that the overall temperature of the material is stable within the appropriate range, and improving fermentation efficiency and feed quality consistency.

[0045] 3. The telescopic heating control plate works in conjunction with the push-pull assembly to flexibly adjust the heating area and stirring disturbance: The lifting chamber, the limiting channel, and the push-pull assembly work together. The lifting drive component drives the telescopic heating control plate to extend and retract within the sliding detection chamber through the connecting rod and the push-pull rod. The limiting protrusion can limit the extension distance to prevent the components from colliding and materials from entering the chamber. The extension length of the heating control plate can be adjusted according to the fermentation stage (initial heating, later anti-sticking) to change the heating area and stirring disturbance intensity, avoid material sedimentation, and ensure that the material is in full contact with air and heat.

[0046] 4. Asynchronous adjustment clamping control component enables differentiated disturbance and heating to adapt to different material characteristics: The support slide column, guide slide column, sliding ball and asynchronous adjustment clamping control component work together to control the inflation / extraction of the extrusion section through an external air source, independently clamp the rotating body on different push-pull rods, so that the telescopic heating control plate on the same support cylinder can achieve asynchronous extension and retraction, forming a "multi-area differentiated disturbance + asynchronous heating" mode, which can adapt to the mixing needs of materials with different particle sizes and moisture content, and can also adjust the heating and disturbance intensity according to the fermentation progress of different areas in the tank, ensuring the synchronicity of fermentation of materials in the whole tank and reducing energy waste;

[0047] 5. Reliability of the protective and limiting structure lifting device: The protective outer shell protects the heating equipment and prevents chemical reactions with the feed; the V-shaped part at the end of the telescopic heating control plate can turbulently prevent material adhesion and breakage; the limiting space and baffle of the sliding ball prevent the ball from falling off; the transverse anti-slip stripes of the extrusion part ensure clamping stability; the rotating body reduces frictional resistance; the overall structure effectively reduces material adhesion and component collision damage, and extends the service life of the device.

Detailed Implementation

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0063] Please see Figures 1-12 This invention provides a high-efficiency constant-temperature feed fermentation tank device for preparing animal feed, wherein the feed is composed of the following components by weight percentage:

[0064] Corn 60%, soybean meal 25%, wheat bran 8%, yeast powder 2%, mineral premix 1%, water 5%;

[0065] The mineral premix comprises a calcium source, a phosphorus source, and a potassium source in a mass ratio of 1:0.8-1.2:0.3-0.5, wherein the calcium source is calcium carbonate, the phosphorus source is dicalcium phosphate, and the potassium source is potassium chloride; the yeast powder is active brewing yeast powder with a viable count ≥1×10⁻⁶. 9 CFU / g.

[0066] Please see Figure 1 The feed preparation method is based on a device including a fermentation tank, temperature control equipment, stirring equipment, aeration equipment, and pH monitoring equipment. The specific steps are as follows:

[0067] Raw material pretreatment: Crush corn and soybean meal into particles with a diameter of 1.0-2.0 mm. Then weigh corn flour, soybean meal, wheat bran, yeast powder and mineral premix according to the above weight percentages, put them into a mixing container and stir for 5-10 minutes to obtain mixed dry material.

[0068] Material loading: Add the water of the above weight percentage to the mixed dry material obtained in step 1, stir evenly, and then transport the material into the fermentation tank and close the tank sealing cover.

[0069] Fermentation control: Stabilize the tank temperature at 30-38℃ using a temperature control device, start the agitator and continuously stir at 30-50 rpm, while simultaneously introducing sterile air into the tank through a ventilation device, controlling the aeration rate to 0.5-1.0 m³ / min. 3 / (h・m 3 materials);

[0070] Process monitoring and temperature control: The pH value of the material in the tank is monitored in real time by pH monitoring equipment. When the pH value is lower than 4.0, the aeration is stopped and stirring is maintained. Fermentation continues for 48-72 hours. During this period, the temperature fluctuation in the tank is maintained at no more than ±2℃ by temperature control equipment to obtain fermented feed.

[0071] By combining the above feed formulation and preparation method, efficient and stable fermented feed production can be achieved. In the field of animal feed fermentation, traditional fermentation often results in insufficient mixing due to uneven particle size of raw materials, or low fermentation efficiency and unstable feed quality (such as pH loss leading to the growth of miscellaneous bacteria) due to insufficient temperature control precision (temperature fluctuations are mostly above ±3℃) and poor coordination between aeration and stirring. In this invention, corn and soybean meal are first crushed to 1.0-2.0mm (this particle size ensures material flowability during subsequent stirring and provides sufficient contact area for microorganisms), and then the dry materials are mixed according to the formula and water is added and stirred to ensure uniform initial moisture content of the materials; after the materials are sealed in the tank, the temperature is stabilized at 30-38℃ using a temperature control device (this temperature range is suitable for active brewing yeast powder (live count ≥1×10⁻⁶)). 9 The optimal fermentation temperature (CFU / g) can significantly improve yeast metabolic efficiency. Simultaneously, the stirring equipment operates at a low speed of 30-50 r / min (to avoid high-speed stirring damaging the yeast cell structure). Aeration equipment introduces 0.5-1.0 m³ / (h・m³ of material) of sterile air (meeting the aerobic fermentation requirements of yeast and inhibiting the growth of anaerobic bacteria). During the process, pH monitoring equipment (such as an insertable pH electrode) is used to monitor the pH in real time. When the pH value drops below 4.0 (at which point the fermentation system has formed an acidic environment, which can inhibit most harmful bacteria; continued aeration can easily lead to excessive acidification of the material), aeration is stopped while stirring continues to ensure uniform heating and reaction of the material. Finally, within a 48-72h fermentation cycle, temperature fluctuations are maintained at ≤±2℃ using temperature control equipment to ensure continuous and efficient yeast metabolism, producing a nutritionally balanced fermented feed with low levels of harmful bacteria.

[0072] In one embodiment of the present invention, please refer to Figures 1-12 The stirring device includes a drive unit and a stirring shaft 1;

[0073] The drive unit is located inside the fermentation tank, and the drive unit is also fixedly connected to the stirring shaft 1, which is rotatably installed inside the fermentation tank.

[0074] The drive unit drives the stirring shaft 1 to rotate inside the fermentation tank to achieve stirring and uniform heating of the feed.

[0075] The stirring shaft 1 is provided with a cross bracket 3 and a cross bracket 5, and a plurality of supporting cylinders 6 are provided between the cross bracket 3 and the cross bracket 5.

[0076] Each of the supporting cylinders 6 is provided with multiple storage and protective shells 7, and each of the multiple storage and protective shells 7 is provided with a heating device, which is signal-connected to the temperature control device.

[0077] The heating device includes a telescopic heating control board 8, a step heating module 9, and a V-shaped section 10;

[0078] The telescopic heating control board 8 is located inside the sliding detection compartment 12 opened on the storage protective shell 7, and the telescopic heating control board 8 is also provided with multiple step heating modules 9, which are connected to the temperature control device via signals.

[0079] The V-shaped section 10 is located at the end of the telescopic heating control plate 8.

[0080] By integrating the stirring and heating equipment, the technical problem of uneven heating of materials due to "blind spots in stirring" in traditional fermenters can be solved. Traditional fermenters often use wall heating or a single stirring shaft heating, which easily leads to local temperature deviations exceeding 5°C, affecting the consistency of microbial fermentation. In this invention, the drive unit (such as a servo motor + gear transmission) is fixed inside the fermenter and connected to the stirring shaft 1. When the stirring shaft 1 is driven to rotate, it drives the cross bracket 1 3 and cross bracket 2 5 to rotate synchronously, thereby driving the multiple supporting cylinders 6 between them to rotate, achieving preliminary stirring of the materials inside the tank. The storage and protective shell 7 on the supporting cylinders 6 (which can be made of high-temperature resistant stainless steel to avoid chemical reaction with the feed) provides installation and protection space for the heating equipment. The telescopic heating control plate 8 in the heating equipment (which uses a metal heating base plate with a non-stick coating to prevent feed sticking) is located in the sliding detection chamber 12 of the storage and protective shell 7. The V-shaped part 10 at its end can be stirred... The mixing process creates turbulence in the materials, preventing feed from sticking together (especially during the extension and retraction of the telescopic heating control plate 8, it can also break up the feed). The multiple step-by-step heating modules 9 (such as ceramic heating elements, each module with independent temperature control) on the telescopic heating control plate 8 are connected to the temperature control equipment (such as a PLC temperature control system). Based on the temperature feedback from different areas inside the tank (collected in real time by temperature sensors), the corresponding step-by-step heating module 9 can be started and stopped independently. In conjunction with the rotation of the supporting cylinder 6 with the stirring shaft 1, the "dynamic mixing + precise zone heating" of the materials inside the tank is achieved, avoiding local overheating or underheating, ensuring that the overall temperature of the materials is stable within the fermentation temperature range of 30-38℃, and improving fermentation efficiency and feed quality consistency.

[0081] In one embodiment of the present invention, please refer to Figures 1-12 It also includes: a lifting chamber 14, which is located in the middle of the supporting cylinder 6, and the lifting chamber 14 is connected to the sliding detection chamber 12 through a limiting channel 13;

[0082] A limiting protrusion 15 is provided between the sliding detection chamber 12 and the limiting channel 13, and the limiting protrusion 15 is used to limit the telescopic heating control plate 8.

[0083] And a push-pull assembly, which is connected to the cross bracket 3 and the telescopic heating control plate 8 respectively, and is slidably connected to the limiting channel 13 and the lifting chamber 14 respectively, for pushing or pulling the telescopic heating control plate 8 to extend and retract within the sliding detection chamber 12, so as to change the heating area and the stirring disturbance effect inside the fermenter.

[0084] The push-pull assembly includes:

[0085] Push-pull rod 17, one end of which is rotatably connected to the side wall of the telescopic heating control plate 8 via a hinge seat 16, and the push-pull rod 17 is also fitted into the limiting groove 13 and slidably connected to the limiting groove 13.

[0086] A connecting rod 18, one end of which is located inside the lifting chamber 14 and is movably connected to the push-pull rod 17;

[0087] And a lifting drive component 4, which is fixedly installed on the cross bracket 3, and the output end of the lifting drive component 4 is also fixedly connected to the connecting rod 18.

[0088] The flexible extension and retraction of the telescopic heating control plate 8 can be achieved through the cooperation of the lifting chamber 14, the limiting structure, and the push-pull assembly. In this invention, the lifting chamber 14 supporting the middle of the cylinder 6 is connected to the sliding detection chamber 12 through the limiting channel 13. The limiting protrusion 15 between the limiting channel 13 and the sliding detection chamber 12 (the other end of the sliding detection chamber 12 can also be provided with a limiting protrusion 15, wherein the limiting protrusion 15 can be made of elastic rubber material, which has both limiting and sealing functions to prevent materials from entering the chamber) can limit the maximum extension and retraction distance of the telescopic heating control plate 8, avoid it from colliding with the tank wall due to excessive extension, and ensure that the telescopic heating control plate 8 is stably stored in the sliding detection chamber 12 when retracting. The lifting drive component 4 in the push-pull assembly (which can be an electric telescopic cylinder with precise stroke control function) is fixed on the cross bracket 3, and its output end is fixedly connected to the connecting rod 18. When it is necessary to adjust the extension length of the telescopic heating control plate 8, the lifting drive component 4... The drive connecting rod 18 moves up and down within the lifting chamber 14. The connecting rod 18 drives the push-pull rod 17 (made of high-strength alloy material to ensure load-bearing capacity and corrosion resistance) to slide within the limiting groove 13. One end of the push-pull rod 17 is connected to the side wall of the telescopic heating control plate 8 through the hinge seat 16, thereby pushing or pulling the telescopic heating control plate 8 to extend and retract within the sliding detection chamber 12. This structure can adjust the heating area according to the fermentation stage—in the early stage of fermentation, when the material is relatively dry, the telescopic heating control plate 8 can be extended to a longer length to increase the contact area with the material and accelerate the material's temperature rise; in the later stage of fermentation, when the material's moisture content increases, the extension length of the telescopic heating control plate 8 can be shortened to reduce material adhesion. At the same time, by changing the extension position of the telescopic heating control plate 8, the intensity of disturbance during stirring can be adjusted to avoid material sedimentation, ensure sufficient contact between the material and air and heat, and improve the uniformity of fermentation.

[0089] In addition, when the temperature difference of the feed inside the tank is large and the temperature distribution is uneven, the extension position of the telescopic heating control plate 8 can be controlled. At the same time, according to the displacement of the telescopic heating control plate 8, more step heating modules 9 can be put into operation (the displacement sensor can detect the movement position of the telescopic heating control plate 8, thereby controlling different numbers of step heating modules 9 to work), so as to ensure that the feed is heated evenly as a whole.

[0090] In one embodiment of the present invention, please refer to Figures 1-12 It also includes: a support slide column 23, which is fixedly connected to the connecting rod 18, and a plurality of guide slide columns 19 are fixedly installed on the support slide column 23;

[0091] Each of the guide slides 19 is provided with a limiting space 21 and a limiting space 22, and a baffle 25 is provided between the limiting space 21 and the adjusting slot 22.

[0092] A sliding ball 26 is fixedly installed at the end of the push-pull rod 17;

[0093] The sliding ball 26 is located within the limiting space 21, and the stop bar 25 is used to limit the sliding ball 26 to prevent it from falling out of the limiting space 21.

[0094] And an asynchronous adjustment clamping control component, which is connected to the stirring shaft 1, the cross bracket 3, the guide slide column 19 and the adjustment slot 22 respectively, and is used to control the asynchronous extension and retraction of different telescopic heating control plates 8 on the same support cylinder 6 in the sliding detection chamber 12.

[0095] The asynchronous adjustment clamping control component includes:

[0096] Transmission channel 2 is provided on the stirring shaft 1 and is connected to an external air source suction device.

[0097] Branch hole 11, the branch hole 11 is opened on the cross bracket 3, and one end of the branch hole 11 is connected to the transmission channel 2, and the other end of the branch hole 11 is connected to the air hole 20.

[0098] Each of the guide slides 19 is provided with an air hole 20, and the air hole 20 is connected to the branch hole 11 through a hose, and a solenoid valve is provided on the hose.

[0099] And an extrusion section 24, which is fixedly installed inside the adjustment slot 22;

[0100] Each of the adjustment slots 22 has two extrusion sections 24 symmetrically arranged inside, and both extrusion sections 24 are connected to the air holes 20 through the channels opened on the step heating module 9 of the transmission channel 2.

[0101] An external air source fills the extrusion section 24 with air, which clamps the push-pull rod 17, restricting its vertical movement. The push-pull rod 17 can only rotate between the two extrusion sections 24. During the rotation of the push-pull rod 17, it pushes the telescopic heating control plate 8 to move outward within the sliding detection chamber 12, thereby changing the extension of the telescopic heating control plate 8 and controlling the number of step heating modules 9 that are engaged, so as to control the heating area of ​​the feed or increase the stirring and disturbance effect.

[0102] A rotating body 27 is rotatably mounted on the push-pull rod 17, and the rotating body 27 is located between the two extrusion parts 24;

[0103] The extrusion section 24 is provided with multiple transverse anti-slip stripes to increase the resistance of the rotating body 27 when it moves upward or downward.

[0104] By cooperating with the supporting sliding column 23, the sliding ball 26, the asynchronous adjustment clamping control component and the rotating body 27, the asynchronous extension and retraction of different telescopic heating control plates 8 on the same supporting cylinder 6 can be realized, which solves the problem that "the disturbance mode of the material in the tank is singular and cannot be adapted to different material characteristics (such as feed with different particle size and moisture)" in the traditional "synchronous extension and retraction" mode. The stirring components of traditional fermentation tanks are mostly synchronous, and the disturbance mode is fixed, which easily leads to the material forming "following flow" and cannot achieve full mixing. In this invention, the supporting slide column 23 is fixedly connected to the connecting rod 18. When the connecting rod 18 moves up and down, it drives multiple guide slide columns 19 on it to move synchronously. The limiting space 21 on the guide slide column 19 is used to accommodate the sliding ball 26 (made of wear-resistant ceramic material to reduce sliding friction) at the end of the push-pull rod 17. The stop strip 25 (made of elastic plastic material with a certain deformation capacity) can prevent the sliding ball 26 from falling out of the limiting space 21, while allowing the sliding ball 26 to rotate within a small range within the limiting space 21. In the asynchronous adjustment clamping control assembly, the transmission channel 2 on the stirring shaft 1 is connected to an external air source suction device (such as an air pump). The press and vacuum generator are connected. The branch hole 11 on the cross bracket 3 diverts the airflow of the transmission channel 2 to the air hole 20 of each guide slide 19 (a one-way valve is installed at the air hole 20 to prevent material backflow). The air hole 20 is connected to the branch hole 11 through a hose with a solenoid valve (which can be independently controlled to achieve precise airflow distribution). The symmetrically arranged extrusion section 24 (which can be an airbag or a telescopic plate with flexible clamping capability) in the regulating slot 22 is connected to the air hole 20 through the channel. When it is necessary to control the extension and retraction of a certain telescopic heating control plate 8, the external air source inflates the corresponding extrusion section 24. After the extrusion section 24 expands, The rotating body 27 on the push-pull rod 17 (the rotating body 27 is made of polytetrafluoroethylene to reduce frictional resistance, and can adopt a rotating shaft structure, which is rotatably connected to the push-pull rod 17. The two ends of the rotating shaft structure are spherical structures, which contact the extrusion part 24, similar to a dumbbell structure) increases the resistance to the vertical movement of the rotating body 27 by the transverse anti-slip stripes on the extrusion part 24, so that the push-pull rod 17 can only rotate around the rotating body 27 between the two extrusion parts 24, thereby pushing the telescopic heating control plate 8 to move outward in the sliding detection chamber 12 (or retracting the telescopic heating control plate 8 by the reverse movement of the lifting drive 4). By independently controlling the inflation / deflation states of different extrusion sections 24, multiple telescopic heating control plates 8 on the same supporting cylinder 6 can extend to different lengths. Combined with the rotation of the stirring shaft 1, this forms a "multi-regional differentiated disturbance + asynchronous heating" mode. This mode can adapt to the mixing needs of materials with different particle sizes, such as corn and soybean meal. It can also adjust the heating and disturbance intensity according to the fermentation progress of different areas in the tank (e.g., if the fermentation in the edge area is slower, the corresponding telescopic heating control plate 8 can be extended longer and more step heating modules 9 can be activated). This ensures the synchronicity of fermentation of materials throughout the tank, improves the stability of fermented feed quality, and reduces energy waste.
