How to deal with kitchen waste efficiently and environmentally friendly has become an urgent problem to be solved. Traditional kitchen waste treatment equipment mainly focuses on the crushing and preliminary decomposition of garbage, but these devices generally have a significant technical defect: the lack of integrated oil-water separation device.

[0003] Existing food waste treatment equipment usually does not have the function of oil-water separation, which results in the grease and water in the food waste cannot be effectively separated inside the treatment equipment. This design deficiency requires the oil-water separation to be carried out outside the equipment, increasing the complexity and cost of the treatment process.

[0015] Specifically, the novel kitchen waste treatment equipment of the present embodiment integrates an oil-water separation device and a fermentation device 2, and the kitchen waste conveying structure realizes effective connection and coordinated work between the two. The oil-water separation device includes an oil-water separation box provided with a kitchen waste inlet, and the kitchen waste inlet allows a user to directly put kitchen waste into the equipment. A kitchen waste separation chamber is provided inside the oil-water separation box, and the chamber is communicated with the kitchen waste inlet for receiving and preliminarily processing the input kitchen waste.

Through this integrated design, the novel kitchen waste treatment equipment can control each component through the control component to realize efficient treatment of kitchen waste.

[0016] Preferably, the fermentation device 2 of this embodiment is located below the oil-water separation device 1. Such a design can effectively utilize the vertical space and reduce the footprint of the equipment. This layout allows the kitchen waste to flow naturally into the fermentation chamber directly through gravity or a simple conveying mechanism, such as a ramp or a screw conveyor, after the oil-water separation is completed, thereby simplifying the conveying process and reducing energy consumption.

[0017] Preferably, the oil-water separation device is provided with an outlet, which is connected to the top inlet of the fermentation device 2. This design ensures that the separated kitchen waste can flow smoothly into the fermentation chamber.

[0018] like Figures 1 to 12 As shown, the fermentation device 2 of this embodiment includes a fermentation box 22, and a fermentation chamber 21 is located in the fermentation box 22. The fermentation chamber is a space for carrying a microbial mixture and degrading kitchen waste. This design allows the fermentation process to be carried out in a controlled environment, which is conducive to maintaining suitable temperature and humidity, thereby improving the degradation efficiency.

[0019] Preferably, the fermentation box 22 and the oil-water separation box 11 of this embodiment are mechanically connected. The fermentation box and the oil-water separation box can be fixed by bolts, buckles, hinges, etc. or other mechanical connectors. This design facilitates the disassembly and maintenance of the equipment, and also provides sufficient connection strength and sealing. The mechanical connection design makes the assembly and disassembly of the equipment easier, and is convenient for daily maintenance and cleaning. Preferably, in other embodiments, the fermentation box 22 and the oil-water separation box 11 are an integrated structure. This design simplifies the manufacturing process of the equipment and enhances the stability and sealing of the structure. The integrated structure also reduces potential leakage points at the connection, improves the reliability of the equipment, and ensures that the equipment has a compact structure, which is easy to install and move. A suitable design can be selected according to actual needs.

[0020] like Figures 1 to 12 As shown, a mechanical connection assembly is provided between the fermentation device 2 and the oil-water separation device 1 of this embodiment, and the mechanical connection assembly includes a hinge member 10. Preferably, the hinge member 10 allows the oil-water separation device to rotate relative to the fermentation device 2, thereby realizing the opening and closing of the device. This design facilitates the user to clean, maintain and inspect the equipment.

[0021] Preferably, the flip-open design reduces the number of parts that need to be disassembled for maintenance, thereby simplifying the maintenance process. Users can perform necessary maintenance and cleaning without disassembling the entire device, reducing maintenance time.

[0022] like Figures 1 to 12 As shown, the oil-water separation box 11 of the present embodiment includes a food waste conveying portion 111 and an oil-water guiding portion 112, the food waste separation chamber 13 is located in the food waste conveying portion 111, and a food waste output port 113 is provided on the oil-water separation box 11, and the food waste conveying structure 3 includes a conveying component 31 provided in the food waste conveying portion 111, and the conveying component 31 can convey the food waste in the food waste separation chamber 13 to the food waste output port 113; the oil-water separation structure 14 includes a filtering component 141 provided between the food waste conveying portion 111 and the oil-water guiding portion 112, and the filtering component 141 can guide the oil and water in the food waste conveying portion 111 to the oil-water guiding portion 112.

[0023] Specifically, the oil-water separation box includes a food waste conveying part, which is provided with a food waste separation chamber, which is used to temporarily store food waste and separate oil and water from the food waste, and the oil-water separation box also includes an oil-water guide part, which is used to receive the oil and water separated from the food waste.

[0024] Specifically, conveying components are provided in the food waste conveying section, which can convey the food waste in the food waste separation chamber to the food waste output port on the oil-water separation box. The conveying components can be a screw conveyor, a conveyor belt or other mechanical conveying devices.

[0025] Preferably, a filter assembly is provided between the food waste conveying part and the oil-water guiding part, and the function of the filter assembly is to guide the oil and water in the food waste conveying part into the oil-water guiding part, and to block the food waste to prevent the food waste from entering the oil-water guiding part, thereby achieving separation of oil and water. Preferably, the filter assembly may include other filter materials such as a filter net and a sieve plate.

[0026] Operation process: The kitchen waste is first placed into the kitchen waste separation chamber, and then pushed to the kitchen waste output port through the conveying component. During the conveying process or the static process of the kitchen waste, the filtering component filters the kitchen waste and oil and water, and guides the oil and water to the oil and water guide part, while the solid kitchen waste continues to be transported to the subsequent processing link.

[0027] By adopting the design of synergistic effects of conveying components and filtering components, effective separation of oil and water in food waste can be achieved, and processing efficiency can be improved. The design of conveying components and filtering components makes operation and maintenance more convenient, reduces the need for manual intervention, and enables food waste processing equipment to be automated.

[0028] Preferably, the fermentation device 2 of this embodiment is further provided with a kitchen waste input port 23 corresponding to the kitchen waste output port 113, the kitchen waste input port 23 is the top inlet of the fermentation device 2, and the kitchen waste output port 113 is the outlet of the oil-water separation device.

[0029] like Figures 1 to 12 As shown, the conveying component 31 of this embodiment includes a conveying screw 311 and a first driving assembly 312 , and the first driving assembly 312 is drivingly connected to the conveying screw 311 .

[0030] Preferably, the conveying component includes a conveying screw for carrying, lifting or compressing the food waste. In this application, the conveying screw is particularly suitable for viscous food waste because its spiral design can effectively push the waste to move along the axial direction of the screw.

[0031] Specifically, the first drive component is connected to the conveying screw and is responsible for providing power to rotate the conveying screw. Specifically, when the first drive component is started, it transmits power to the conveying screw, causing the conveying screw to start rotating. As the conveying screw rotates, the food waste in the food waste separation chamber is captured by the spiral blades and pushed forward, and finally transported to the food waste output port. The conveying screw can provide continuous and uniform material flow.

[0032] like Figures 1 to 12 As shown, the oil-water separation box 11 of this embodiment is provided with a first door component, which includes a first door 115 and a second drive component 116. The second drive component 116 can drive the first door 115 to block or keep the first door 115 away from the food waste outlet 113.

[0033] Specifically, the oil-water separation box is provided with a first box door, which is a movable door component for blocking or opening the kitchen waste outlet. The design of the first box door can be sliding, hinged or other mechanical structures to meet different operational requirements.

[0034] Specifically, the first door component also includes a second drive assembly, which is a power source for driving the first door to open or close, and the second drive assembly is connected to the first door through a mechanical connection. When it is necessary to prevent food waste from overflowing from the output port or to maintain the sealing of the equipment, the second drive assembly drives the first door to move to a blocking position, thereby closing the food waste output port. When the food waste needs to be transported to the next processing stage, the second drive assembly moves the first door away from the food waste output port, thereby opening the output port and allowing the food waste to pass through.

[0035] Through the control of the second drive assembly, the opening and closing of the first door can be automated, reducing the need for manual operation and improving operational efficiency.

[0036] like Figures 1 to 12 As shown, the oil-water separation box 11 of this embodiment is also provided with a box door cleaning component, which includes a clean water output nozzle 117 and a second water body providing component. The second water body providing component is connected to the clean water output nozzle 117, and the second water body providing component can provide water to the clean water output nozzle 117 for spraying to clean the surface of the first box door 115.

[0037] Preferably, the door cleaning component includes one or more clean water output nozzles, which are located at appropriate positions of the oil-water separation box 11 and are used to spray clean water to clean the door surface. The nozzle design can be fixed or adjustable to accommodate doors of different sizes and shapes.

[0038] Specifically, the door cleaning component also includes a second water body providing component, which is a water supply system responsible for providing clean water. The second water body providing component may include a water pump, a water tank, a piping system, etc. to ensure that clean water can be transported to the clean water output nozzle.

[0039] When the first door needs to be cleaned, the second water supply component will be started to transport clean water through the pipe to the clean water output nozzle, which will then spray the clean water onto the surface of the first door to wash away residual kitchen waste, oil stains and other stains. The cleaning operation can be automated, triggered by a preset program or sensor in the control component; it can also be manual, with the operator controlling the control component to start as needed.

[0040] The door cleaning component ensures the regular cleaning of the surface of the first door, reduces the growth of bacteria and odors, and improves the hygiene standards of the equipment. The automated cleaning system reduces the need for manual cleaning, saves labor costs, and improves cleaning efficiency. Regular cleaning and maintenance help extend the service life of the equipment and reduce equipment failures caused by dirt accumulation. It can effectively prevent food waste from drying and hardening and remaining on the first door, hindering the closing of the first door, or causing the first door to fail to seal the food waste outlet 113.

[0041] like Figures 1 to 12 As shown, the second water body providing component of this embodiment outputs hot water, which is convenient for cleaning the oil stains on the surface of the first door 115 and the kitchen waste stuck on the surface of the first door 115. Preferably, the second water body providing component not only includes a water pump, a water tank and a pipeline system, but also integrates a heating device, which can be an electric heater, a steam heater or other effective heating methods, for heating water to an appropriate temperature.

[0042] Specifically, the second water body providing component can heat water to a specific temperature, and then transport it to the clean water output nozzle through the pipe system. When the first box door needs to be cleaned, the heated hot water will be sprayed onto the surface of the first box door through the clean water output nozzle. The hot water can effectively dissolve oil stains and loosen adhered kitchen waste, thereby more thoroughly cleaning the first box door. The use of hot water can significantly improve the cleaning effect, especially when dealing with oil stains and kitchen waste with strong adhesion, hot water can dissolve and remove these dirt more quickly.

[0043] like Figures 1 to 12 As shown, the oil-water guide portion 112 of this embodiment is located at the bottom of the food waste conveying portion 111, and the filter assembly 141 includes a partition plate arranged between the food waste conveying portion 111 and the oil-water guide portion 112 and a plurality of filter holes arranged on the partition plate. The oil and water in the food waste conveying portion 111 can flow into the oil-water guide portion 112 through the filter holes.

[0044] Specifically, the oil-water guide part is located at the bottom of the food waste conveying part, which is a special area for collecting and separating oil and water, while the food waste conveying part is located above the oil-water guide part, which is used to transport food waste to a specific treatment area. This part adopts a conveying component 31 to reliably transport food waste.

[0045] Specifically, the filter assembly includes a partition plate arranged between the food waste conveying part and the oil-water guide part. The main function of the partition plate is to separate food waste and liquid. A plurality of filter holes are arranged on the partition plate to allow oil and water to pass through while blocking larger solid food waste. Through these filter holes, liquid parts such as grease and water can flow into the oil-water guide part below, while the solid parts remain in the food waste conveying part.

[0046] During the food waste transportation process, solid waste moves in the transportation part, while the mixed liquid part such as grease and water flows into the oil-water guide part through the filter holes on the partition plate. By setting a filter component between the food waste transportation part and the oil-water guide part, solid-liquid separation is achieved and the efficiency of oil-water separation is improved.

[0047] like Figures 1 to 12As shown, the partition plate, the oil-water guide portion 112 and the food waste conveying portion 111 of this embodiment are an integrated structure. The integrated structure reduces seams and connection points, improves the sealing and durability of the structure, and simplifies the manufacturing and installation process.

[0048] In other embodiments, the partition plate, the oil-water guide portion 112 and the food waste conveying portion 111 are a mechanical connection structure, which firmly connects the partition plate, the oil-water guide portion and the food waste conveying portion together through bolts, welding, snaps or other mechanical connection methods. The mechanical connection structure provides a certain flexibility and can quickly repair damaged parts of the oil-water separation box without replacing the entire box, which is convenient for disassembly and maintenance, while also ensuring the stability of the structure.

[0049] like Figures 1 to 12 As shown, the oil-water guide portion 112 of the present embodiment includes an oil-water conveying box located at the bottom of the kitchen waste conveying portion 111, one end of the oil-water conveying box is provided with a recovery component 119, the bottom of the oil-water conveying box has a certain slope, the oil and water in the oil-water conveying box can flow toward the recovery component 119 through the bottom slope of the oil-water conveying box and the self-weight of the oil and water, and the oil and water are collected and processed by the recovery component 119.

[0050] Preferably, the oil-water guide portion includes an oil-water conveying box located at the bottom of the food waste conveying portion. The box is designed to collect the oil-water mixture flowing in from the food waste conveying portion through the filter holes. The bottom of the oil-water conveying box is designed to have a certain slope. This slope design allows the oil and water to rely on their own gravity to flow from high to low, that is, to flow in the direction of the recovery component.

[0051] Preferably, the recovery component is located at one end of the oil-water conveying box, and its structure is designed to effectively collect and process the oil and water flowing thereto. The oil and water naturally flow to the recovery component through the bottom slope in the oil-water conveying box, and the recovery component is responsible for separating and collecting the oil and water.

[0052] Preferably, the recovery component includes an oil-water separation valve, which can discharge the oil and water in the oil-water transfer box, and extract the oil and water into the oil-water collection box in the food waste treatment equipment or discharge it to the external oil-water collection box or other collection structure for collection. The appropriate design can be selected according to actual needs.

[0053] like Figures 1 to 12As shown, the oil-water separation box 11 of the present embodiment is also provided with an oil-water separation box cleaning component capable of cleaning the inside thereof, the oil-water separation box cleaning component includes a plurality of water spray holes 1111 and a first water body providing component 1112, the plurality of water spray holes 1111 are spaced apart on the inner wall of the oil-water separation box 11, the first water body providing component 1112 is connected to the plurality of water spray holes 1111, the first water body providing component 1112 can provide water to the water spray holes 1111 for spraying, so as to clean the inner wall of the oil-water separation box 11.

[0054] The cleaning component includes a plurality of water spray holes, which are spaced apart on the inner wall of the oil-water separation box 11. The first water body providing component is connected to the plurality of water spray holes and is responsible for providing water to the water spray holes. The component can be a water pump or other water supply device that can ensure sufficient water pressure and water volume.

[0055] When the oil-water separation box 11 needs to be cleaned, the first water providing component is started to provide water to multiple water spray holes. The water is sprayed out through the water spray holes to form a high-pressure water flow to flush the inner wall of the oil-water separation box 11 opposite to the water spray holes. The high-pressure water flow can effectively wash away the oil and impurities attached to the inner wall. The sewage after flushing will flow into the oil-water transfer box through the filter holes on the partition plate, or be discharged through a specially designed sewage outlet, ensuring that the oil-water separation box 11 remains clean. By setting up cleaning components, automatic cleaning of the oil-water separation box 11 is achieved.

[0056] like Figures 1 to 12 As shown, the first water body providing component 1112 of this embodiment outputs hot water, which is convenient for cleaning the oil stains on the inner wall of the oil-water delivery box and the kitchen waste stuck on the inner wall surface of the oil-water delivery box.

[0057] Specifically, hot water can dissolve and remove oil stains more effectively, especially for grease and kitchen residues attached to the inner wall of the oil-water transfer box. Hot water has a certain bactericidal and disinfecting effect, which can reduce the growth of bacteria and microorganisms and maintain the hygiene of the oil-water separation box. The temperature of hot water can accelerate the decomposition and softening of grease, making the cleaning process faster and more thorough.

[0058] Specifically, the first water body providing component not only provides water, but also outputs hot water. The first water body providing component includes a heating device, such as an electric heater or other heating system to ensure that the water reaches a suitable temperature. When the oil and water transfer tank needs to be cleaned, the first water body providing component is started to output hot water to multiple water spray holes. The hot water is sprayed out through the water spray holes to flush the inner wall of the oil and water transfer tank. The impact force and temperature of the hot water can effectively remove oil stains and kitchen residues.

[0059] like Figures 1 to 12As shown, the stirring structure of this embodiment includes a stirring shaft assembly 24 and a third driving assembly 25. The third driving assembly 25 is transmission-connected to the stirring shaft assembly 24 to provide power to drive the stirring shaft assembly to rotate.

[0060] During the fermentation process, the third drive component is started and drives the stirring shaft component to rotate through the transmission connection to stir the microbial mixture and kitchen waste in the fermentation chamber. The function of the stirring structure is to make the microbial mixture and kitchen waste evenly mixed in the fermentation chamber, ensure that the microorganisms and kitchen waste are in full contact, and promote the fermentation reaction. Stirring can also prevent the microbial mixture and kitchen waste from precipitating in the fermentation chamber, keep the substances in the fermentation chamber evenly distributed, and avoid local over-concentration or over-diluted.

[0061] like Figures 1 to 12 As shown, the stirring shaft assembly 24 of this embodiment includes a main shaft 241 transmission-connected to the third driving assembly 25 and a plurality of first secondary shafts 242 spirally distributed along the shaft body of the main shaft 241. The design of the first secondary shaft increases the contact area and stirring effect of stirring, making the stirring more uniform and efficient.

[0062] Specifically, the third drive assembly is started and drives the main shaft to rotate through a transmission connection. The rotation of the main shaft drives the entire stirring shaft assembly to rotate. As the main shaft rotates, the first secondary shaft distributed spirally along the main shaft also rotates. The design of the first secondary shaft enables the stirring blades or stirring arms to more effectively stir the kitchen waste and / or microbial mixture, promoting uniform mixing and sufficient contact.

[0063] Specifically, through the synergistic effect of the main shaft and the first secondary shaft, the stirring shaft assembly can more effectively stir the substances in the fermentation chamber, thereby improving the stirring efficiency and the fermentation effect.

[0064] Specifically, the first sub-shaft is arranged in this manner at intervals, which can reduce the pressure of the mixture on the first sub-shaft. Compared with the existing design of the first sub-shaft with spiral integral blades, the design of multiple first sub-shafts arranged at intervals can effectively reduce the load of the mixture on the first sub-shaft without affecting the conveying and stirring functions of the stirring structure, thereby extending the service life of the first sub-shaft.

[0065] Preferably, the design of the stirring shaft assembly is convenient for disassembly and maintenance, and the first secondary shaft can be regularly inspected and replaced to ensure stirring effect and equipment life.

[0066] like Figures 1 to 12 As shown, the first secondary shaft 242 of this embodiment includes a shaft body 2421 and a blade 2422 disposed on one end of the shaft body 2421, and the other end of the shaft body is connected to the main shaft 241, and the blade 2422 has a certain curvature.

[0067] The first secondary shaft includes an axis body and a paddle disposed at one end of the axis body, the paddle blade is used to stir the material in the fermentation chamber, the paddle blade is usually designed to maximize the stirring effect, and the paddle body has a certain curvature, which helps to provide greater stirring force and better fluid dynamics.

[0068] Preferably, the other end of the shaft body is connected to the main shaft, and this connection can be welding, threaded connection or other types of mechanical connection methods, ensuring that the first secondary shaft is stable during the stirring process and can withstand the force caused by the stirring. Through the blades on the first secondary shaft, the material in the fermentation chamber can be more effectively stirred, thereby accelerating the fermentation process. The curved blades are usually more efficient and can provide a strong stirring effect while consuming less energy.

[0069] like Figures 1 to 12 As shown, the paddle 2422 of this embodiment is in the shape of a shovel, with a wide shovel surface and a certain curvature. This design helps to better push and turn over the materials during the stirring process, similar to the action of a shovel digging in the soil, thereby promoting the circulation and mixing of the materials in the fermentation chamber. The wide shovel surface and curvature design of the paddle enable it to turn over the materials, turn the materials at the bottom to the surface, or push the materials on the surface to the bottom, so as to achieve uniform distribution and full contact of the materials.

[0070] like Figures 1 to 12 As shown, two oppositely arranged second sub-shafts 243 are also provided on the main shaft 241 of this embodiment. The two second sub-shafts 243 are located at both ends of the main shaft 241 and close to the inner wall of the fermentation chamber 21. This arrangement helps to directly act on the edge area of ​​the fermentation chamber, which is usually a stirring dead corner and easily leads to material accumulation.

[0071] Preferably, the second sub-shaft 243 of the present embodiment is in a T-shape. The T-shaped second sub-shaft 243 has a larger stirring range. The T-shaped second sub-shaft 243 can stir and transport kitchen waste and / or humus fertilizer in the dead corners at both ends of the fermentation box, thereby preventing kitchen waste and / or humus fertilizer from accumulating at both ends of the fermentation box.

[0072] Since a large amount of material usually accumulates at the corners of the inner walls at both ends of the fermentation chamber, the secondary shaft with a paddle body having a certain curvature usually cannot stir the material there. In fact, the weight of the material may cause the paddle blades 2422 on the secondary shaft to be damaged. In addition, since the secondary shaft is designed to be detachably connected to the main shaft, the secondary shaft is more easily affected by the weight of the material on the main shaft, resulting in positional displacement or the secondary shaft falling off the main shaft, affecting the normal operation of the secondary shaft.

[0073] Preferably, the T-shaped secondary shaft is more evenly stressed, reducing the stress concentration caused by single-point stress, thereby reducing the risk of damage to the secondary shaft and making it less likely to be damaged. With regard to the design in which the second secondary shaft 243 is detachably connected to the main shaft, the secondary shaft is not easily affected by the weight of the material on the main shaft, and is unlikely to be displaced or fall off the main shaft, thereby ensuring the normal operation of the secondary shaft.

[0074] like Figures 1 to 12 As shown, the fermentation box 22 of this embodiment is provided with an air inlet 221 and an exhaust port 222 which are respectively connected to the fermentation chamber 21. The fermentation device 2 also includes an air filtration system 4 connected to the exhaust port 222. The air filtration system 4 can process the gas discharged from the fermentation chamber 21 to meet the emission requirements.

[0075] Specifically, the fermentation box is provided with an air inlet connected to the fermentation chamber for providing fresh air into the fermentation chamber to support the activity of microorganisms and promote the fermentation process. The fermentation box is also provided with an exhaust port for exhausting the gases generated during the fermentation process, including carbon dioxide, water vapor and possible volatile organic compounds.

[0076] The fermentation device 2 also includes an air filtration system connected to the exhaust port, which is responsible for processing the gas discharged from the fermentation chamber. The air filtration system can filter and process the gas discharged from the fermentation chamber to remove harmful substances therein, such as odor, particulates, volatile organic compounds, etc., so as to meet environmental emission requirements.

[0077] like Figures 1 to 12 As shown, the air filtration system 4 of this embodiment includes a gas disinfection component 41 and a gas filter component 42 connected in sequence, the gas filter component 42 includes a gas filter box 421 and a gas filter component 422 arranged in the gas filter box 421, the gas disinfection component 41 includes a gas disinfection box 411 and a gas disinfection component 412 arranged in the gas disinfection box 411, the exhaust port 222 is connected to the gas disinfection component 412, and the gas filter box 421 is provided with a gas exhaust port 423.

[0078] By setting up gas disinfection components and gas filtration components, the air filtration system can provide multiple protections to ensure the safety and cleanliness of the exhaust gas. Combined with the disinfection and filtration functions, the system can efficiently handle various harmful gases and microorganisms generated during the fermentation process, thereby improving the environmental performance of the entire fermentation system. The modular design of the gas disinfection box and the gas filtration box facilitates maintenance and replacement of components, thereby improving the system's operational convenience and maintainability.

[0079] like Figures 1 to 12 As shown, the gas disinfection box 411 of this embodiment includes a first disinfection part 4111 , and the gas disinfection assembly 412 includes a plurality of UV lamps arranged at intervals in the first disinfection part 4111 .

[0080] The gas generated during the fermentation process first enters the gas disinfection box through the exhaust port, and then enters the first disinfection section. When passing through multiple UV lamps arranged at intervals, ultraviolet rays can kill microorganisms. After the gas is disinfected by the UV lamp, pathogens are effectively eliminated, which improves the cleanliness of the gas. The disinfected gas will continue to enter the gas filter component for further processing.

[0081] Preferably, the multiple UV lamps arranged at intervals are designed to facilitate maintenance and replacement, ensuring the continuity and reliability of the disinfection effect. Through the joint action of multiple UV lamps, the gas in the gas disinfection box can be fully exposed to ultraviolet rays to achieve a thorough disinfection effect.

[0082] like Figures 1 to 12 As shown, the gas disinfection box 411 of this embodiment further includes a second disinfection section 4112 , the first disinfection section 4111 and the second disinfection section 4112 are arranged adjacent to each other, and the gas disinfection component 412 further includes an ozone disinfection component arranged in the second disinfection section 4112 .

[0083] Specifically, the second disinfection part is arranged adjacent to the first disinfection part, and is another part of the gas disinfection box. An ozone disinfection component is arranged inside the second disinfection part for further disinfecting the gas.

[0084] Specifically, the ozone disinfection component is disposed in the second disinfection part and disinfects the gas by generating ozone.

[0085] The gas generated during the fermentation process first enters the gas disinfection box through the exhaust port, and then enters the second disinfection section for further disinfection by the ozone generated by the ozone disinfection component. Ozone can oxidize organic and inorganic pollutants in the gas, kill residual microorganisms, and remove odors.

[0086] like Figures 1 to 12 As shown, the gas disinfection assembly 412 of this embodiment also includes a high temperature disinfection assembly arranged in the second disinfection part 4112, which achieves the effect of high temperature disinfection by heating the gas. The gas generated during the fermentation process first enters the gas disinfection box through the exhaust port. Preferably, in this embodiment, the gas first enters the first disinfection part, and when passing through a plurality of UV lamps arranged at intervals, the ultraviolet rays can kill these microorganisms.

[0087] The gas that has been treated with ultraviolet disinfection continues to enter the second disinfection part, and the high-temperature disinfection component further kills the microorganisms in the gas. After high-temperature disinfection, the gas continues to pass through the ozone disinfection component, and ozone can further kill residual microorganisms and remove odors.

[0088] After the triple disinfection of ultraviolet light, high temperature and ozone, the pathogens are effectively eliminated and the cleanliness of the gas is improved. The disinfected gas will continue to enter the gas filtration component for further processing.

[0089] Preferably, the gas can first enter the first disinfection part and then flow into the second disinfection part, or first enter the second disinfection part and then flow into the first disinfection part. The appropriate design can be selected according to actual needs, and the order of disinfection can also be selected according to actual needs. The appropriate disinfection process will not be repeated here.

The side wall of the partition box body 4113 is provided with a gas through hole 4114, and the gas through hole 4114 is communicated with the first disinfection part 4111 and the second disinfection part 4112 respectively.

[0091] Specifically, the partition box body 4113 is arranged inside the gas disinfection box, and is used to separate the gas disinfection box into two independent disinfection parts, namely the first disinfection part and the second disinfection part. A gas through hole is provided on the side wall of the partition box body, which is used to allow gas to flow from the first disinfection part to the second disinfection part.

[0092] Through the design of the partition box, the gas disinfection box is divided into two independent disinfection parts, so that the gas can be processed sequentially between different disinfection parts, ensuring the maximum disinfection effect and making the structure of the gas disinfection box more compact.

[0093] like Figures 1 to 12 As shown, the gas disinfection box 411 of this embodiment is provided with a gas inlet 4115 and a gas outlet 4116, the gas inlet 4115 is communicated with the first disinfection part 4111, and the gas outlet 4116 is communicated with the second disinfection part 4112, or, the gas inlet 4115 is communicated with the second disinfection part 4112, and the gas outlet 4116 is communicated with the first disinfection part 4111.

[0094] Preferably, the gas sterilization box 411 can have a variety of configurations: The first configuration: the gas enters the first disinfection part through the gas inlet, the gas enters the first disinfection part, and is disinfected by multiple UV lamps arranged at intervals. The gas treated with ultraviolet disinfection passes through the gas through holes on the side wall of the partition box and enters the second disinfection part. After the gas enters the second disinfection part, the gas is heated to a sufficiently high temperature by the high-temperature disinfection component to further kill the microorganisms in the gas. After the high-temperature disinfection, the gas continues to pass through the ozone disinfection component. Ozone can further oxidize and disinfect organic and inorganic pollutants in the gas, kill residual microorganisms, and remove odors. The gas that has undergone multiple disinfection treatments is discharged from the disinfection box from the gas outlet.

[0095] The second configuration: the gas enters the second disinfection section through the gas inlet. The gas first enters the second disinfection section and is heated to a sufficiently high temperature by the high-temperature disinfection component to kill the microorganisms in the gas. After the high-temperature disinfection, the gas continues to pass through the ozone disinfection component. Ozone can further oxidize and disinfect the organic and inorganic pollutants in the gas, kill the residual microorganisms, and remove odors. The gas that has been dually disinfected by high temperature and ozone enters the first disinfection section through the gas through holes on the side wall of the partition box. The gas enters the first disinfection section and passes through multiple UV lamps arranged at intervals to further ensure the cleanliness of the gas. The gas that has been multiply disinfected is discharged from the disinfection box from the gas outlet.

[0096] There are also various configurations where the positions of the high temperature disinfection component and the ozone disinfection component are interchanged, which will not be described here.

[0097] The settings of the gas inlet and gas outlet can be flexibly configured according to actual needs, allowing the gas to pass through which disinfection part first, thereby improving the adaptability of the system.

[0098] like Figures 1 to 12 As shown, the gas filter box 421 of this embodiment includes an outer box 424 and an inner box 425 arranged in the outer box 424, a heat dissipation gap 426 is provided between the outer box 424 and the inner box 425, the outer box 424 is provided with an air outlet 4241 and an assembly port 4242, one end of the inner box 425 extends to the outside of the assembly port 4242 and is connected to the output end of the gas disinfection component 41, the other end of the inner box 425 extends into the outer box 424 and is arranged corresponding to the assembly port 4242, and the gas filtering component 422 includes an activated carbon filter arranged in the inner box 425.

[0099] Specifically, the outer box is the external structure of the gas filter box, providing overall support and protection. The inner box is arranged inside the outer box and actually accommodates the part of the gas filter component. One end of the inner box extends to the outside of the air inlet of the outer box and is connected to the output end of the gas disinfection component. The other end of the inner box extends to the inside of the outer box and is arranged corresponding to the air inlet.

[0100] Specifically, the heat dissipation gap is the space between the outer box and the inner box, which is used to dissipate heat and prevent the internal temperature from being too high to affect the filtering effect.

[0101] Specifically, the gas is first disinfected by a gas disinfection component, and the disinfected gas enters the gas filter box through one end of the inner box connected to the output end of the gas disinfection component. The gas passes through the activated carbon filter in the inner box. The activated carbon filter can adsorb organic matter, odor and other impurities in the gas to further purify the gas. The filtered gas is discharged through the other end of the inner box and enters the outer box. The gas filtered by the inner box is discharged through the air outlet of the outer box, completing the entire filtration process.

[0102] Specifically, one end of the inner box extends to the outside of the air inlet and is connected to the gas disinfection component, ensuring that the disinfected gas directly enters the filter box, thereby improving the overall efficiency of the system.

[0103] like Figures 1 to 12 As shown, the outer box 424 of this embodiment is formed in a trumpet shape, the air outlet 4241 is located at the end of the outer box 424 with a smaller inner diameter, and the assembly port 4242 is located at the end of the outer box 424 with a larger inner diameter.

[0104] Preferably, the trumpet-shaped outer box design optimizes the gas flow path, and the gradual contraction from the air inlet with a larger inner diameter to the air outlet with a smaller inner diameter increases the gas flow rate and filtration efficiency, thereby improving the heat dissipation efficiency.

[0105] like Figures 1 to 12 As shown, the heating component 20 of the present embodiment can heat the fermentation box 22 to evaporate the moisture of the microbial mixture and / or kitchen waste in the fermentation box to meet the humidity requirement. When the humidity inside the fermentation box needs to be adjusted, the heating component is started to heat the fermentation box. The temperature rise causes the moisture inside the fermentation box to evaporate. The evaporated moisture reduces the humidity inside the fermentation box, thereby meeting the preset humidity requirement.

[0106] Preferably, a humidity sensor can be used to monitor the humidity in the fermentation box in real time, and the working state of the heating component can be adjusted through the control system to ensure that the humidity remains within an ideal range.

[0107] The heating component can effectively evaporate the moisture in the fermentation box, control the humidity during the fermentation process, ensure a suitable fermentation environment, promote microbial activity and fermentation effect, optimize the fermentation environment, and improve fermentation efficiency and quality. Preferably, the humidity sensor and control component are combined to automatically adjust the working state of the heating component and accurately control the humidity.

[0108] like Figures 1 to 12 As shown, the heating component 20 of this embodiment includes a heating film arranged on the outer wall of the fermentation box 22, and heats the content in the fermentation box by resistive heating.

[0109] Preferably, the heating component 20 may also adopt structures such as electric heating tubes, hot air circulation systems, infrared heaters, etc., and a suitable design may be selected according to actual needs.

[0110] like Figures 1 to 12 As shown, a main discharge port 26 and a collecting component 27 are provided on one side of the fermentation box 22 of this embodiment. The material in the fermentation box 22 can be transported and guided to the main discharge port 26 for discharge through the stirring structure, and collected by the collecting component 27.

[0111] Preferably, the stirring structure can be used to guide the material in the fermentation box to the main discharge port, and the material is discharged from the fermentation box through the main discharge port and enters the collecting component, which collects the material discharged from the main discharge port for subsequent processing or use.

[0112] Specifically, the stirring structure effectively transports the material to the main discharge port, ensuring rapid and smooth discharge of the fermented material, and the uniform stirring and discharge process ensures the stability of the fermentation quality.

[0113] Specifically, the design of the stirring shaft assembly 24 with the above-mentioned main shaft 241 and multiple first secondary shafts 242 spirally distributed along the shaft body of the main shaft 241 is adopted, so that the stirring structure has both stirring and conveying functions, making the structure of the food waste processing equipment more compact and eliminating the need to set up an additional conveying structure.

[0114] like Figures 1 to 12 As shown, the fermentation box 22 of this embodiment is provided with a second door component, which includes a second door 28 and a fourth drive assembly 29. The fourth drive assembly 29 can drive the second door 28 to block or keep the second door 28 away from the main discharge port 26.

[0115] Specifically, the second door component controls the opening and closing of the second door through the fourth driving assembly.

[0116] When the material needs to be discharged, the fourth drive assembly drives the second box door away from the main discharge port, so that the main discharge port is opened and the material can be discharged. When the material does not need to be discharged, the fourth drive assembly drives the second box door to block the main discharge port to prevent the material from being discharged.

[0117] When fermentation is completed or part of the material needs to be discharged, the control system starts the fourth drive component, and the fourth drive component drives the second box door to open the main discharge port, and the material is discharged through the main discharge port. After the discharge is completed, the fourth drive component drives the second box door to close the main discharge port to ensure the system is sealed.

[0118] Preferably, the fourth drive assembly can accurately control the opening and closing of the second door to ensure effective blocking or opening of the main discharge port. Combined with the control system, the opening and closing operation of the second door can be automated to reduce manual intervention.

[0119] like Figures 1 to 12 As shown, the collecting assembly 27 of this embodiment includes a collecting box located on one side of the fermentation box 22 . The top of the collecting box 271 has an opening, and the main discharge port 26 is located above the collecting box 271 .

[0120] Specifically, the material is discharged from the fermentation box through the main discharge port, and the main discharge port is located above the collecting box. The discharged material enters the collecting box through the opening at the top of the collecting box and is effectively collected by the collecting component. The design of the opening at the top of the collecting box simplifies the discharge and collection process of the material and reduces complex mechanisms. The user only needs to take away the collection box 271 that has collected the kitchen waste to complete the collection. It has the advantages of simple structure and easy operation.

[0121] like Figures 1 to 12 As shown, the collecting assembly 27 of this embodiment also includes a guide plate 272 arranged on one side of the fermentation box 22. The guide plate 272 has a certain slope. The guide plate 272 can guide the material discharged from the main discharge port 26 to the collecting box 271. With such a design, the kitchen waste can accurately fall into the collecting box 271 from the main discharge port 26, ensuring the scattering of the kitchen waste, keeping the working environment clean and the accurate collection of the kitchen waste.

[0122] like Figures 1 to 12 As shown, the novel kitchen waste treatment equipment of this embodiment also includes an observation component 5, which is an observation window for users to observe the status of kitchen waste and / or humus fertilizer in the fermentation box 22. When the kitchen waste in the fermentation box 22 that cannot be decomposed by microorganisms such as bones reaches a certain amount, the kitchen waste is discharged through the stirring structure and the total discharge port 26 on one side of the fermentation box 22; or when the humus fertilizer in the fermentation box 22 reaches the discharge requirement or a certain inventory, the material is discharged through the stirring structure and the total discharge port 26. Preferably, the observation component 5 includes a first observation port provided on the fermentation box 22; preferably, the observation component 5 also includes a second observation port provided on the oil-water separation device 1, and the first observation port and the second observation port are correspondingly arranged.

[0123] like Figures 1 to 12 As shown, the novel kitchen waste treatment equipment of this embodiment also includes a simulated sunlight device 6. Specifically, the simulated sunlight device 6 can provide a light source simulating sunlight for the fermentation chamber 21, which can effectively enhance the microbial activity during the fermentation process and improve the fermentation efficiency.

[0124] Preferably, the sunlight simulation device uses a light source of a specific wavelength to simulate the spectrum of natural sunlight. Preferably, the simulated sunlight device 6 can adjust the light intensity to meet the needs of different fermentation stages.

[0125] Preferably, the light can also assist in regulating the temperature in the fermentation box. By controlling the light, the humidity in the fermentation box can be indirectly affected, the stability of the fermentation environment can be maintained, and a suitable fermentation environment can be provided.

[0126] like Figures 1 to 12 As shown, the simulated sunlight device of this embodiment includes a fermentation lamp 61, which has the advantages of simple structure, convenient operation and low cost.

[0127] like Figures 1 to 12 As shown, the fermentation lamp 61 of this embodiment is located outside the fermentation box 22, and the simulated sunlight device also includes a light-transmitting window 62 arranged on the top of the fermentation box 22, and the light-transmitting window 62 is arranged corresponding to the fermentation lamp 61.

[0128] Specifically, the fermentation lamp is located outside the fermentation box, which prevents other components in the fermentation box 22 from affecting the fermentation lamp 61 and preventing the fermentation lamp 61 from being damaged. In addition, it can also prevent the moisture generated by the fermentation material and the temperature environment in the fermentation box from directly interfering with the fermentation lamp.

[0129] Preferably, the light-transmitting window is made of a material with high light transmittance to ensure that the light source can efficiently penetrate and be evenly distributed in the fermentation box. The light-transmitting window introduces the light source provided by the fermentation lamp into the fermentation box to avoid interference of the external environment on the light source, while ensuring the sealing of the fermentation environment.

[0130] The fermentation lamp efficiently introduces light into the fermentation box through the light-transmitting window, enhancing the activity of microorganisms. The design of the light-transmitting window ensures the stability of temperature and humidity in the fermentation box, providing a suitable fermentation environment.

[0131] Preferably, the fermentation lamp is located outside the fermentation box, which is convenient for maintenance and replacement, and reduces interference with the fermentation process.

[0132] like Figures 1 to 12 As shown, the number of the simulated sunlight device 6 in this embodiment is at least one.

[0133] like Figures 1 to 12 As shown, the light-transmitting window 62 of this embodiment is located in the middle area of ​​the top of the fermentation box 22 to ensure that most areas in the box can be illuminated, promote microbial activity, optimize the fermentation environment, and thus improve the fermentation efficiency and product quality. Through this innovative design, the fermentation device 2 can operate more efficiently, stably and flexibly in actual applications. In other embodiments, the number of simulated sunlight devices 6 can be multiple, evenly arranged on the top of the fermentation box 22 to form omnidirectional illumination, or at specific times, different simulated sunlight devices 6 are set to start and stop to simulate the change of sunlight, further enhancing the simulation authenticity of sunlight. Preferably, the number of light-transmitting windows 62 can correspond to the number of simulated sunlight devices 6, or the size of the light-transmitting windows 62 can be enlarged so that the sunlight of all simulated sunlight devices 6 can be irradiated into the fermentation chamber 21.

[0134] like Figures 1 to 12As shown, the simulated sunlight device of this embodiment is located between the oil-water separation device 1 and the fermentation device 2. With such a design, the oil-water separation device 1 and the fermentation device 2 can protect the simulated sunlight device 6 to prevent external factors from accidentally touching or colliding with the simulated sunlight device 6, causing the simulated sunlight device 6 to malfunction or be damaged.

[0135] like Figures 1 to 12 As shown, the simulated sunlight device of this embodiment also includes a fixing bracket 63 for fixing the fermentation lamp 61. Specifically, the fixing bracket is located outside the fermentation box and is used to fix the fermentation lamp. The fixing bracket firmly fixes the fermentation lamp in a predetermined position to prevent the light source from being offset or damaged due to vibration or other external forces. Preferably, the fixing bracket can have a certain adjustment function, allowing the angle and height of the fermentation lamp to be adjusted as needed to optimize the lighting effect.

[0136] Preferably, the light-transmitting window 62 is made of heat-resistant polycarbonate or tempered glass, and the simulated sunlight device can illuminate the inside of the fermentation box 22 .

[0137] Preferably, the method for using the control method of a novel food waste processing device of this embodiment comprises the following steps: S1. Place the medium and bacteria into the fermentation chamber, control the temperature at 40-45°C, and ferment for 20-30 hours; S2, putting the food waste to be processed into the food waste separation chamber 13 through the food waste inlet 12, and starting the oil-water separation structure 14 through the control component to separate the food waste from the oil and water, and the separation treatment time is 3-5 minutes; S3, starting the food waste conveying structure 3 through the control component to guide the food waste that has been separated from oil and water into the fermentation chamber 21, and starting the stirring structure and the heating component through the control component; S4, S4, performing a first pretreatment and a second decomposition treatment, the heating component (20) performs heating, and the stirring structure rotates forward or reversely to perform stirring; S5. After the food waste is processed, some of the processed food waste will be removed.

[0138] Specifically, the medium includes a carrier material and a composite auxiliary agent, the composite auxiliary agent includes a first composite auxiliary agent and a second composite auxiliary agent, and the bacterial species is a composite bacterial body. The carrier material and the first composite auxiliary agent are put into a fermentation chamber. After the composite bacterial body is added, it is first allowed to stand for 0.5-1 hour at 15-25°C for thawing. This process is to allow the bacterial body to gradually recover from a frozen state to an active state to avoid cell damage caused by temperature mutations. It is allowed to stand for 20-30 hours at 40-45°C and a humidity of less than or equal to 40% to ensure that the composite bacterial body is fully combined with the carrier material and activate the activity of the composite bacterial body. This high temperature and low humidity environment helps the bacterial body to reproduce rapidly and produce sufficient biological enzymes, providing a strong biological power for the subsequent kitchen waste degradation process. At the same time, the low humidity environment can prevent the bacterial body from excessively absorbing water and maintain its structural stability. In this process, the addition of the second composite auxiliary agent can not only adjust the pH to optimize the degradation environment, but also enhance the degradation ability of the composite bacterial agent to further promote the activity and degradation efficiency of the bacterial body.

[0139] Specifically, after filtering the water from the kitchen waste to be processed, remove the excess water to reduce the humidity fluctuation during the degradation process and prevent the problem of excessive water inhibiting the activity of the bacteria and affecting the degradation efficiency. Put it into the container, start the stirring structure, heating component and simulated sunlight device, the air filtration system can discharge the gas generated during the treatment process to prevent pressure accumulation, and the simulated sunlight device has a positive effect on the activity of thermophilic green sulfur bacteria and thermophilic red spiral bacteria. During the kitchen waste treatment process, the simulated sunlight device continuously illuminates the environment to improve the activity of thermophilic green sulfur bacteria and thermophilic red spiral bacteria. When the humidity in the environment is too low, the clean water output nozzle can add water to the fermentation chamber through the kitchen waste input port for humidification. When the humidity in the environment is too high, the stirring structure and heating component are started for heating and stirring, and the air filtration system exhausts air and discharges the water.

[0140] First, the kitchen waste is subjected to an oil-water separation process in the kitchen waste separation chamber 13 through the oil-water separation structure 14, and the separation process takes 3-5 minutes. Then, the kitchen waste is guided to the fermentation chamber 21 through the kitchen waste conveying structure 3. At this time, the second driving component 116 drives the first box door 115 to be continuously opened, and waits for 1-3 minutes to ensure that the kitchen waste enters the fermentation chamber 21. Then, the box door cleaning component cleans the surface of the first box door 115 for 3-10 seconds, and the oil-water separation box cleaning component cleans the inner wall of the oil-water separation box 11 for 25-60 seconds. Then, the sewage will be discharged through the sewage outlet to wait for the next oil-water separation action.

[0141] Then, the first pretreatment time is 2-5 hours, the first pretreatment temperature is 40-45℃, the first pretreatment humidity is 35-70%, the stirring structure rotates forward for 3-5 minutes, then reverses for 3-5 minutes, and then stops for 20 minutes. The first pretreatment time is set according to the food waste capacity of the fermentation chamber. The first pretreatment can cut and crush the food waste. The second pretreatment time is 4-8 hours, the second pretreatment temperature is 45-65℃, the second pretreatment humidity is 35-60%, the stirring structure rotates forward for 2 minutes, then reverses for 2 minutes, and then stops for 10 minutes. This temperature range and humidity conditions are the most active environment for most thermophilic bacteria, which helps to accelerate the degradation process of food waste. The stirring time lasts for 4-8 hours to ensure that the bacteria are fully in contact with the food waste and evenly distributed, and can also promote the circulation of oxygen and maintain the balance of anaerobic and aerobic bacteria. During the stirring process, the biological enzymes released by the bacteria will act on the organic matter in the food waste and decompose it into small molecules. After a period of stirring and degradation, the food waste will gradually form decomposition products. These decomposition products include small molecules such as water, carbon dioxide, organic acids, ammonia, and some incompletely degraded solid residues, thereby achieving volume reduction and harmlessness.

[0142] Regularly remove the food waste that exceeds the upper limit and re-add the carrier material and the second composite additive. Regularly remove some of the decomposed products in the container to reduce interference with the degradation process, help avoid accumulation of materials in the treatment container, and recycle some of the decomposed products as organic fertilizers, and free up space for new food waste to be degraded. After removing the decomposed products, re-add the carrier material and the second composite additive to the container to replenish the consumed nutrients and active ingredients to ensure the continuous degradation ability of the bacteria.

[0143] Specifically, the stirring structure is rotated to discharge the material through the opened main discharge port. When discharge is not required, the fourth drive assembly drives the second box door to block the main discharge port to prevent the material from being discharged.

[0144] Calculated by mass, the composite bacteria are 5-10 parts, the composite auxiliary agent is 5-10 parts, and the carrier material is 80-100 parts; the composite bacteria include thermooleophilic Bacillus, thermophilic Pseudomonas, thermophilic cellulose-degrading bacteria, thermophilic actinomycetes, thermophilic nitrite bacteria, thermophilic nitrate bacteria, thermophilic green sulfur bacteria, thermophilic Rhodospirilla, and Bacillus coagulans; the carrier material includes modified zeolite, modified biochar, modified kaolin, sawdust, coconut bran, and rice bran; the first composite auxiliary agent includes peptone, glycerol, trehalose, glycine, and sodium cysteine ​​glutamate; the second composite auxiliary agent includes sodium bicarbonate, lipase, cellulase, hemicellulase, protease, and amylase.

[0145] Specifically, the composite bacteria of the present invention help to accelerate the decomposition process of kitchen waste, the composite additive is used to provide nutrients required for microbial growth, can adjust the environment during the treatment process and accelerate the decomposition of organic matter, the carrier material can provide the support and environment required for microbial growth and activity, and its adsorption performance helps to extend the service life of the composite bacteria and reduce the replacement frequency. The present invention improves the decomposition efficiency during the treatment of kitchen waste through the synergistic effect of composite bacteria composed of multiple microorganisms, utilizes different carrier materials and composite additives, reduces the generation of unpleasant gases, and reduces treatment costs.

[0146] Further, calculated by mass, 1-2 parts of thermo-oleophilic geobacillus, 0.5-1.5 parts of thermophilic pseudomonas, 0.5-1.5 parts of thermophilic cellulose-degrading bacteria, 1-2 parts of thermophilic actinomycetes, 0.25-0.5 parts of thermophilic nitrite bacteria, 0.25-0.5 parts of thermophilic nitrate bacteria, 0.25-0.5 parts of thermophilic green sulfur bacteria, 0.25-0.5 parts of thermophilic red spiral bacteria, and 0.5-1.5 parts of Bacillus coagulans. Specifically, the composite thalli is composed of a variety of thermophilic microorganisms with efficient degradation capabilities. The thermophilic microorganisms can rapidly proliferate and effectively degrade various organic matter in kitchen waste under high temperature conditions. The thermophilic microorganisms in the composite thalli can quickly adapt to the high temperature environment of the kitchen waste processor, shorten the adaptation period, and quickly enter the efficient degradation state. The stability and efficiency of the composite bacterial agent reduce the number and frequency of microbial supplementation, thereby reducing the processing cost. At the same time, when thermophilic microorganisms and decomposition products are taken out as organic fertilizers for absorption by green plants, they will become dormant at normal temperature and will not affect the ecological environment.
