Description

Technical Field

[0001] This utility model relates to the technical field of fermentation devices, and in particular to a precise fermentation control device for sesame silage. Background Technology

[0002] Fermentation equipment is widely used in industries such as dairy, beverages, bioengineering, pharmaceuticals, and fine chemicals. Silage, as a common technology for extending the shelf life of green fodder, significantly improves palatability while reducing crude fiber content. This process can achieve efficient preservation of forage nutrients, which is crucial for ensuring a stable supply of livestock feed during winter, spring, and drought periods. Protein is the basic nutrient for livestock production, so the reserve of high-protein feed is essential. However, in moderate to severe saline-alkali areas, the yield of traditional high-protein forage such as alfalfa is low due to soil environmental limitations, directly affecting the efficiency of plant nutrient absorption. How to balance the supply of high-protein roughage with the nutritional needs of ruminants in such areas remains a pressing technical challenge. Sesbania, as an annual high-protein leguminous herb, can grow rapidly in adverse conditions such as saline-alkali and waterlogged areas, as well as in moderate to severe saline-alkali areas, effectively alleviating the shortage of high-protein forage in these areas. The fermentation equipment, with the fermentation tank as its core, achieves efficient fermentation of sesbania silage through processes such as raw material stirring, sealed anaerobic fermentation, precise environmental control, and discharge maintenance.

[0003] Most small and medium-sized farms still use traditional pit or bag storage, relying on manual experience to control raw material chopping, lacking real-time monitoring methods, resulting in inaccurate fermentation environment control, localized material accumulation or insufficient fermentation, affecting fermentation effect, easy blockage during discharge, and excessive residual material. Due to lack of scraping, the material near the tank wall easily forms an adhesive layer. Traditional inoculant dosing methods are difficult to accurately match the fermentation process, and the uncontrolled release sequence of inoculants can easily lead to metabolic competition, resulting in a 30% reduction in the synergistic efficiency of fiber-degrading bacteria and lactic acid bacteria. The heating system relies on contact electric heating tubes, which have inherent defects of low thermal efficiency and poor temperature uniformity. The waste gas treatment process lacks volatile organic compound recovery devices, and resource components such as ethanol and ethyl acetate produced during fermentation are directly emitted, polluting the environment. Utility Model Content

[0004] The purpose of this invention is to provide a precise fermentation control device for sesame silage, addressing the issues raised in the background art where most small and medium-sized farms still use traditional pit or bag storage, relying on manual experience to control raw material chopping, lacking real-time monitoring methods, resulting in inaccurate fermentation environment control, localized material accumulation or insufficient fermentation affecting fermentation efficiency, easy blockage during discharge, excessive residual material, and the formation of an adhesive layer near the tank wall due to lack of scraping. Traditional inoculant delivery methods are difficult to precisely match the fermentation process, and uncontrolled release of inoculants can easily lead to metabolic competition, resulting in a 30% reduction in the synergistic efficiency of fiber-degrading bacteria and lactic acid bacteria. The heating system relies on contact electric heating tubes, which have inherent defects such as low thermal efficiency and poor temperature uniformity. Furthermore, the lack of a volatile organic compound recovery device in the waste gas treatment process leads to the direct emission of resource components such as ethanol and ethyl acetate produced during fermentation, causing environmental pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision fermentation control device for sesame silage, comprising a base, a column fixedly installed on the upper surface of the base, a discharge hopper fixedly connected to the upper end of the column, a fermentation tank fixedly connected to the upper end of the discharge hopper, a sealing ring fixedly installed on the upper surface of the outer ring of the fermentation tank, the fermentation tank and the sealing cover being tightly fitted together by the sealing ring, a guide plate fixedly connected to the inner surface of the discharge hopper, and first connecting rods fixedly through both sides of the discharge hopper, a vibration motor provided at the left end of the first connecting rod, and a guide plate fixed to the inner surface of the discharge hopper. The fermenter is equipped with a screen, and a rotating shaft is mounted on the upper surface of the screen. A drive motor is connected to the flange on the upper surface of the rotating shaft. A spiral blade is fitted around the outer ring of the rotating shaft. A second connecting rod is fixedly mounted on one side of the rotating shaft. A scraper is fixedly mounted on the inner side of the fermenter. A pneumatic control unit is fixedly mounted on the upper surface of the base. An exhaust pipe is connected to the right flange of the pneumatic control unit, and the lower end of the exhaust pipe is connected to a waste gas recovery bottle. A high-frequency electromagnetic coil is wound around the outer wall of the fermenter, and a heat insulation layer is fixedly mounted on the outer wall. Biodegradable multilayer microcapsules are fitted around the outer ring of the rotating shaft.

[0006] Preferably, the discharge hopper and the guide plate are connected by a first connecting rod, and the upper end of the guide plate is fixedly connected to the screen.

[0007] Preferably, the rotating shaft and the scraper are fixedly connected by a second connecting rod, and the scraper is driven to rotate by a drive motor via the rotating shaft.

[0008] Preferably, the left flange of the pneumatic controller is connected to an air pipe, and the sealing cover is connected to the pneumatic controller via the air pipe.

[0009] Preferably, a ladder is fixedly installed on the upper surface of the base, a platform is fixedly connected to the upper end of the ladder, and a guardrail is fixedly installed on the upper surface of the platform.

[0010] Preferably, a temperature sensor is fixedly installed on the rear side of the sealing cover, and the sensing end of the temperature sensor penetrates through the sealing cover.

[0011] Preferably, the high-frequency electromagnetic coil is made of copper enameled wire, the heat insulation layer is made of ceramic fiber material, and the multi-layer microcapsule encapsulates salt-resistant lactic acid bacteria in one layer, fiber-degrading bacteria in the middle layer, and aroma-producing yeast in three layers.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This sesame silage precision fermentation control device uses a spiral blade driven by a rotating shaft to chop and mix the material. A synchronously rotating scraper, connected to the inner wall of the fermentation tank via a second connecting rod, continuously scrapes away adhering material, preventing the formation of a stubborn adhesive layer on the tank wall. A pressure controller, connected to a sealing cap via an air pipe, precisely regulates the oxygen concentration inside the tank and maintains a constant pressure. A temperature sensor monitors the fermentation temperature in real time. The base is equipped with ladders, platforms, guardrails, and other safety operating components, providing a stable maintenance platform for personnel. The discharge hopper, combined with a vibrating motor and guide plate design, prevents material adhesion and blockage during discharge. The pH-triggered slow-release design of the layered microcapsules (one layer releases yeast oxygen-consuming bacteria in 4 hours, the middle layer releases cellulase in 12 hours, and the three layers release salt-tolerant lactic acid bacteria in 24 hours) precisely matches the fermentation process (oxygen consumption during start-up → cell wall disruption during degradation → anaerobic digestion during acid production), avoiding metabolic competition caused by asynchronous release of microorganisms. This increases the fiber degradation rate by 25% and shortens the anaerobic environment establishment time by 60%. The electromagnetic induction heating jacket uses non-contact eddy current heating to overcome the limitations of metal tank materials, solving the problems of long pretreatment time for high-fiber materials and nutrient loss due to local overheating. The waste gas recovery bottle condenses and collects the volatile organic compounds (such as ethanol and ethyl acetate) produced during fermentation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a precise fermentation control device for sesame silage, including a base 1, a column 2 fixedly installed on the upper surface of the base 1, a discharge hopper 3 fixedly connected to the upper end of the column 2, a fermentation tank 4 fixedly connected to the upper end of the discharge hopper 3, a sealing ring 5 fixedly installed on the upper surface of the outer ring of the fermentation tank 4, the fermentation tank 4 and the sealing cover 6 being tightly fitted together by the sealing ring 5, a guide plate 7 fixedly connected to the inner surface of the discharge hopper 3, a first connecting rod 8 fixedly connected through both sides of the discharge hopper 3, a vibration motor 9 provided at the left end of the first connecting rod 8, and a screen 10 fixedly installed on the inner side of the discharge hopper 3. A rotating shaft 11 is provided on the surface of the fermenter 4. A drive motor 12 is connected to the flange on the upper surface of the rotating shaft 11. A spiral blade 13 is fitted around the outer ring of the rotating shaft 11. A second connecting rod 14 is fixedly installed on one side of the rotating shaft 11. A scraper 15 is fixedly installed on the inner side of the fermenter 4. A pneumatic control machine 16 is fixedly installed on the upper surface of the base 1. An exhaust pipe 22 is connected to the right flange of the pneumatic control machine 16. The lower end of the exhaust pipe 22 is connected to a waste gas recovery bottle 23. A high-frequency electromagnetic coil 24 is wound around the outer wall of the fermenter 4. A heat insulation layer 25 is fixedly installed on the outer wall. A biodegradable multilayer microcapsule 26 is fitted around the outer ring of the rotating shaft 11.

[0020] Furthermore, the discharge hopper 3 is connected to the guide plate 7 via the first connecting rod 8. The upper end of the guide plate 7 is fixedly connected to the screen 10. Through the setting of the guide plate 7, the vibration motor 9 drives the guide plate 7 and the screen 10 to generate high-frequency micro-amplitude vibration. The vibration breaks the adhesion between the material and the plate surface, so that the silage material can still be discharged smoothly.

[0021] Furthermore, the rotating shaft 11 and the scraper 15 are fixedly connected by the second connecting rod 14. The scraper 15 is driven to rotate by the drive motor 12 through the rotating shaft 11. With the setting of the scraper 15, the scraper 15 is closely attached to the inner wall of the fermenter 4 through the second connecting rod 14, continuously scraping off the adhering material and avoiding the formation of a stubborn adhesive layer on the tank wall.

[0022] Furthermore, the left flange of the pneumatic control unit 16 is connected to an air pipe 17. The sealing cover 6 is connected to the pneumatic control unit 16 through the air pipe 17. Through the settings of the pneumatic control unit 16, the pneumatic control unit 16 collects the air pressure data in the sealed environment in real time through the pressure sensor and transmits it to the controller. The controller has a built-in algorithm that compares the measured value with the set value and generates a command to drive the air pipe 17 to adjust the air pressure. When the measured air pressure is lower than the set value, the air pipe 17 is opened to replenish the gas. When it is higher than the set value, the air pipe 17 is opened to release the gas, so that the air pressure is stabilized in the target range.

[0023] Furthermore, a ladder 18 is fixedly installed on the upper surface of the base 1, and a platform 19 is fixedly connected to the upper end of the ladder 18. A guardrail 20 is fixedly installed on the upper surface of the platform 19. The ladder 18 solves the problems of no protection, low efficiency, and difficult maintenance of traditional fermentation equipment when operating at height.

[0024] Furthermore, a temperature sensor 21 is fixedly installed on the rear side of the sealing cap 6, and the sensing end of the temperature sensor 21 penetrates through the sealing cap 6. Through the setting of the temperature sensor 21, the sensing end of the temperature sensor 21 monitors the fermentation temperature in real time.

[0025] Furthermore, the high-frequency electromagnetic coil 24 is made of copper enameled wire, the heat insulation layer 25 is made of ceramic fiber material, and the multi-layer microcapsule 26 encapsulates salt-resistant lactic acid bacteria in one layer, fiber-degrading bacteria in the middle layer, and aroma-producing yeast in the third layer. Through the setting of the multi-layer microcapsule 26, the fermentation process is precisely matched, avoiding metabolic competition caused by asynchronous release of strains.

[0026] Working Principle: This precision fermentation control device for sesame silage delivers the sesame raw material to be processed into the fermentation tank 4 through the feed inlet. The airtight seal of the fermentation tank 4 is achieved through a sealing cover 5 and an annular sealing ring 6. The output shaft of the drive motor 7 is connected to the central connecting shaft 8 via a coupling, driving the coaxially mounted spiral blade 9 and scraper 10 to rotate synchronously. The spiral blade 9, when rotating at high speed, can shear and crush the sesame stalks, and achieve tumbling and mixing of the material through axial thrust, ensuring uniform mixing of the inoculant and raw material. The scraper 10 and... Fermentation tank 4 is fitted together, and during rotation, it continuously removes material adhering to the wall of fermentation tank 6, preventing the formation of a stubborn adhesive layer that affects heat transfer efficiency. The pressure controller 16, model DTT, is connected to the gas interface on the sealing cover 6 via gas pipe 17. It regulates the gas pressure based on an external differential pressure sensor, creating stable anaerobic conditions for lactic acid bacteria fermentation. The right flange of the pressure controller 16 is connected to an outlet pipe 22, and the lower end of the outlet pipe 22 is connected to a waste gas recovery bottle 23. The waste gas recovery bottle condenses and collects the volatile organic compounds produced during fermentation. The temperature sensor 21, model FOX-2004, enables real-time monitoring of fermentation temperature. A high-frequency electromagnetic coil 24 is wound around the outer wall of the fermenter 4, and a heat-insulating layer 25 is fixedly installed on the outer wall. The coil is connected to a high-frequency power supply; when an alternating current is applied, a rapidly changing electromagnetic field is generated. The electromagnetic induction heating jacket generates heat through non-contact eddy current heating, overcoming the limitations of metal tank materials and solving the problems of long pretreatment times for high-fiber materials and nutrient loss due to localized overheating. The outer ring of the moving shaft 11 is fitted with biodegradable multi-layer microcapsules 26, which, through three layers... The microcapsules feature a pH-triggered sustained-release design, with the first layer releasing yeast oxygen-consuming bacteria over 4 hours, the middle layer releasing cellulase over 12 hours, and the third layer releasing salt-tolerant lactic acid bacteria over 24 hours. This precisely matches the fermentation process and avoids metabolic competition caused by asynchronous release of microorganisms. The equipment base 1 is equipped with a ladder 18 with guardrails 20 and a platform 19 on the side, providing a safe and stable space for personnel to maintain the equipment. During the discharge stage, the vibration motor 9 drives the guide plate 7 and the screen 10 to generate high-frequency micro-amplitude vibration. The vibration breaks the adhesion between the material and the plate surface, allowing the silage material to continue to discharge smoothly.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
