Most of the equipment is mainly composed of a feeding system, a mixing chamber, a drive device and a discharge port. It usually uses spiral, blade or double-axis mixing to fully mix feeds of different coarseness and physical properties. In order to further improve the quality of pig feed, modern feed introduces bacterial liquid during the mixing process. By adding bacterial liquid during the feed mixing process, the growth of beneficial microorganisms is promoted and the intestinal health of pigs is enhanced. In actual application, the equipment can automatically adjust the mixing time and the amount of bacterial liquid added to achieve precise and automated feed preparation to meet the nutritional needs of different feeding stages.

[0051] Example 1

[0052] like Figure 1-7 As shown, this embodiment discloses a system for stirring feed and heat preservation fermentation, including a feed stirring system and a heat preservation fermentation box, wherein the feed stirring system and the heat preservation fermentation box are placed independently; the feed stirring system includes a main cabinet frame, wherein the main cabinet frame is provided with a stirring component 1, a transmission unit 2, a control box and a fixing frame 3;

[0053] The main cabinet frame includes a mixing chamber 4 and a first barrel chamber 5; the bottom of the mixing chamber 4 is connected to the top of the first barrel chamber 5; the mixing component 1 is arranged in the mixing chamber 4 in the main cabinet frame, and the end of the mixing component 1 extends into the first barrel chamber 5;

[0054] The fixing frame 3 is connected to the stirring assembly 1 and the transmission unit 2 respectively, and the transmission unit 2 controls the stirring assembly 1 to move in the vertical direction by controlling the fixing frame 3;

[0055] A second barrel compartment 6 is provided in the heat-insulating fermentation box; a barrel moving vehicle and a barrel 8 are provided in the first barrel compartment 5 and the second barrel compartment; a temperature sensor is provided in the barrel 8, and the temperature sensor is electrically connected to the controller in the control box; heat-insulating cotton for keeping feed warm is laid on the wall of the heat-insulating fermentation box.

[0056] The stirring assembly 1 includes a first motor 101, a fixing flange 102 and a cover plate 103; the fixing flange 102 fixes the first motor 101 on the fixing frame 3, and the fixing frame is fixedly connected to the cover plate 103;

[0057] A through hole is provided in the center of the cover plate 103, and the power output end of the first motor 101 is connected to the power rotating shaft 104, and the end of the power rotating shaft 104 extends into the first barrel compartment 4;

[0058] A spiral flip stirring head 105 is also provided in the vertical direction of the power rotating shaft 104 .

[0059] The stirring assembly 1 adopts a spiral flip stirring head 105, which allows the feed to be flipped multiple times in the vertical direction, ensuring uniform mixing of the feed components; the power rotating shaft 104 is connected to the first motor 101, and is fixed to the fixed frame 3 through the fixing flange 102, ensuring smooth operation during the stirring process and improving the stirring efficiency.

[0060] The cover plate 103 is provided with a fan installation slot, and a hot air blower 106 is provided at the fan installation slot. The hot air blower 106 is used for auxiliary heating during the stirring process and drying the generated water vapor;

[0061] The cover plate 103 is integrated with a hot air blower 106, which not only provides necessary auxiliary heating during the stirring process, but also can timely dry the water vapor generated by heating to avoid the quality of the feed being reduced due to increased moisture, thereby maintaining the feed in the best condition.

[0062] The feed is placed in the barrel 8, and the bacterial liquid is added and stirred. During the fermentation and stirring process, the activity of the bacterial liquid and the temperature of the feed need to be kept relatively stable. The stirring process requires a water heater to perform secondary series preheating of the reaction water, while keeping the temperature of the feed and the barrel 8 relatively constant; the spiral flip stirring head 105 inside the barrel 8 cooperates with the cleaning unit 9 to spray and wash by adding disinfectant water with a pH value of 2.5; at the same time, the fermentation incubator adopts internal circulation constant temperature insulation to keep the feed fermentation temperature relatively constant.

[0063] The cleaning unit 9 is installed on the inner surface of the cover plate 103, and a sprinkler pipe clamp 901 and a sprinkler pipe 902 are also fixed on the inner surface of the cover plate 103. A hot water inlet is provided on the cover plate 103, and one end of the sprinkler pipe 902 passes through the hot water inlet and is fixed on the sprinkler pipe clamp 901; the water heater is installed on the inner wall of the main cabinet frame, and the water heater is connected to the sprinkler pipe 902 through a hot water delivery pipeline.

[0064] The main function of the cleaning unit 9 is to automatically clean the equipment, ensure the cleanliness of the inner surface of the equipment, and reduce the impact of residual feed on the operation of the equipment and the fermentation process. The following is a description of a specific embodiment:

[0065] After the equipment stops running, ensure that there is no material residue in the mixing chamber 4 and the first barrel chamber 5. The operator sends a command to start the cleaning unit 9 through the control box. The cleaning unit 9 is electrically connected to the control box, and the entire cleaning process is controlled by an automatic program; the water outlet end of the sprinkler pipe 902 is fixed to the inner surface of the cover plate 103 through the sprinkler pipe clamp 901 to ensure that the spraying angle covers the key areas of the mixing chamber, the barrel chamber and the mixing component.

[0066] The water heater is connected to the watering pipe 902 through a hot water delivery pipeline to supply constant temperature hot water. The hot water temperature can be set by the control box according to the cleaning requirements, usually 50°C to 80°C. The watering pipe 902 starts to spray hot water, and a uniform water flow is generated under pressure, covering the surfaces of the mixing chamber 4, the power rotating shaft 104, the spiral flip-type mixing head 105 and other components to remove the attached feed residues.

[0067] According to the equipment cleaning requirements, multiple cleaning cycles can be set, and each cleaning lasts 5 to 10 minutes; if deeper cleaning is required, an appropriate amount of environmentally friendly detergent can be added through the hot water inlet, and the sprinkler pipe 902 can spray hot water with detergent for cleaning, which can effectively dissolve grease and difficult-to-clean feed residues.

[0068] After cleaning is completed, the hot air blower 106 is started to blow hot air through the fan installation slot on the cover plate 103 to evaporate the moisture in the cabin to prevent the equipment parts from rusting or mildewing due to residual moisture.

[0069] The spiral flip stirring head 105 is a key component. Its special spiral structure makes it easy for feed residues and fermentation bacteria to adhere, making it difficult to clean.

[0070] The spiral part of the spiral flip type stirring head 105 can be designed to have a reasonable pitch (7cm to 15cm), which can not only ensure the stirring efficiency, but also allow the water flow or cleaning liquid to fully flow through the spiral gap to avoid residual accumulation; at the same time, the surface of the stirring head is treated with a smooth coating or an anti-stick coating to reduce the adhesion of the feed and facilitate cleaning. A number of guide holes are set on the spiral structure of the spiral flip type stirring head 105 to facilitate the cleaning liquid to penetrate the entire stirring head structure during rotation cleaning and fully cover and clean. During the cleaning process, the power rotating shaft 104 and the transmission unit 2 are started in coordination to make the spiral flip type stirring head 105 rotate at a low speed. The high-pressure hot water or cleaning liquid sprayed by the sprinkler pipe 902 fully covers its surface and gaps during the rotation of the spiral stirring head. The rotating action produces a water flow disturbance effect to wash away the attachments. The sprinkler pipe 902 sprays the spiral flip type stirring head 105 with high-pressure water flow, and the strong water flow can penetrate into the bottom of the spiral and the joint of the rotating shaft to clear the hard-to-reach areas.

[0071] A multi-hole adjustable nozzle is installed at the end of the sprinkler pipe 902, and the spray angle can be adjusted according to the spiral characteristics of the mixing head to ensure that the cleaning liquid can cover all directions of the spiral flip type mixing head 105, including the inside, outside and the area connected to the rotating shaft. In the program of the cleaning unit 9, the additional spraying time and water pressure intensity are set for the key parts of the spiral flip type mixing head 105 (such as the spiral root and the rotating shaft connection area) to ensure thorough cleaning. After the cleaning is completed, the hot air is blown out by the hot air blower 106 on the cover plate 103 to quickly dry the surface of the mixing head to prevent secondary contamination or rust caused by residual moisture. The infrared sensor in the system can detect the cleanliness of the surface of the mixing head. If the residue is not cleaned up, the system will automatically start the secondary cleaning program until the cleanliness meets the standard.

[0072] The system is equipped with a cleaning unit 9 with a built-in sprinkler pipe 902, which is connected to a water heater. After use, it can be automatically cleaned with hot water and mixed with hot water during the mixing process, which greatly reduces the workload of manual cleaning. At the same time, it effectively prevents the accumulation of residues inside the equipment and prolongs the service life of the equipment. Even in winter or cold areas, it can still achieve the best state of feed mixing and stirring. The wastewater generated during the cleaning process is automatically discharged to the wastewater treatment system through the drainage pipe at the bottom of the bilge, ensuring that the equipment cleaning process is environmentally friendly and pollution-free. After the cleaning is completed, the system will automatically shut down and check whether the equipment is cleaned through an infrared sensor or a temperature sensor. If residues are detected, the system will prompt and restart the cleaning program until the cleaning is completed.

[0073] Example 2

[0074] like Figure 1-7 As shown, this example provides another system for stirring feed and heat preservation fermentation, which is similar to Example 1, except that:

[0075] The transmission unit 2 includes a second motor 201 and a transmission chain 202 . A transmission tooth which is transmission-connected to the transmission chain 202 is provided on the power output end of the second motor 201 .

[0076] The fixing frame 3 is configured as a horizontal T-shape as a whole, and is provided with an upper beam and a lower beam in the vertical direction; a first chain fixing bracket 301 is fixedly provided on the upper beam; and a second chain fixing bracket 302 is fixedly provided on the lower beam;

[0077] One end of the transmission chain 202 is fixedly connected to the first chain fixing bracket 301 ; the other end of the chain is cooperatively connected to the second chain fixing bracket 302 .

[0078] The transmission unit 2 also includes a motor rotating group 203 fixed on the main cabinet frame, and the power output end of the motor rotating group 203 is connected to the rolling bearing; the circumference of the rolling bearing is matched with the chain transmission teeth; the transmission chain is mounted and connected to the chain transmission teeth.

[0079] The transmission unit 2 adopts the design of the transmission chain 202 and the transmission gear to ensure that the power output of the second motor 201 can be efficiently transmitted to the stirring system. The motor rotating group 203 realizes the stable drive of the chain through the matching connection with the rolling bearing, and enhances the reliability and working accuracy of the transmission unit 2.

[0080] A pulley slot 304 is provided in the mixing chamber 4 and fixed in the main cabinet frame; a pulley assembly 303 composed of a plurality of pulleys is installed in the pulley slot 304; the pulley assembly is connected to the fixed frame 3;

[0081] The transmission unit 2 is also provided with a drag chain, one end of which is fixedly connected to the fixing frame 3 and the other end is connected to the main cabinet frame; the transmission unit 2 moves in the vertical direction, thereby driving the auxiliary fixing frame 3 to move smoothly in the vertical direction. The design of the drag chain further enhances the movement stability of the fixing frame 3, ensuring that the transmission unit 2 is not affected by external resistance when moving up and down.

[0082] The fixing frame is designed as a horizontal T-shaped structure, with an upper beam and a lower beam, and the first chain fixing bracket 301 and the second chain fixing bracket 302 are used to stably support the transmission chain 202. The pulley assembly 303 further ensures the stable movement of the fixing frame in the vertical direction, avoiding possible shaking and deviation during the movement.

[0083] Two infrared sensor probes are provided on the main cabinet frame, which respectively sense the highest and lowest positions of the transmission chain moving in the vertical direction. The infrared sensor probes equipped on the main cabinet frame can monitor the highest and lowest positions of the transmission chain 202 in real time, accurately control the movement range of the stirring component 1, prevent excessive movement, and protect the safety and long-term operation of the equipment.

[0084] Example 3

[0085] like Figure 1-7 As shown, this example provides another system for stirring feed and heat preservation fermentation, which is similar to Example 1, except that:

[0086] The barrel moving vehicle is configured as a push-pull type, and is provided with an arc fixing frame fixedly connected to the barrel; the first barrel compartment 5 and the second barrel compartment 6 are both fixed with a barrel limiting ring; the barrel moving vehicle adopts a push-pull design, which is convenient for operators to freely move the barrel 8 in the first barrel compartment 5 and the second barrel compartment 6, and the barrel moving vehicle is provided with a push-pull panel, and the height of the push-pull panel is respectively adapted to the size of the first barrel compartment 5 and the second barrel compartment 6; the bottom surface of the barrel moving vehicle is respectively adapted to the bottom surface size of the first barrel compartment 5 and the second barrel compartment 6, and the barrel moving vehicle can connect the barrel 8 with the first barrel compartment 5 by push-pull, and the barrel 8 and the mixing compartment 4 form a mixing space together; the barrel moving vehicle is moved to the second barrel compartment 6 by push-pull, and push-pull connection is formed together with the second barrel compartment 6 to form a heat preservation chamber. The arc fixing frame ensures that the barrel 8 is stable and does not shake during the movement, and the limiting ring further fixes the position of the barrel 8 to avoid affecting the operation effect due to the movement of the barrel during the mixing and heat preservation process.

[0087] The feed mixing system is also provided with a bacterial liquid constant temperature room, which is installed at the lower part of the control box, and a bacterial liquid constant device 7 is provided in the bacterial liquid constant temperature room, and the bacterial liquid constant device 7 is set as a porous hollow type; a constant temperature heating component is provided in the bacterial liquid constant device 7. A bacterial liquid storage barrel can be placed in the bacterial liquid constant temperature room, and the bacterial liquid in the storage barrel is transmitted to the mixing cabin through a conveying pipeline for mixing and stirring the feed.

[0088] The system has added a bacterial liquid constant temperature chamber with a porous hollow interior configuration. The bacterial liquid constant device 7 ensures that the bacterial liquid is always at a suitable temperature during the process of being transported and added to the mixing barrel 8. The constant temperature heating component can ensure temperature stability and improve the activity of the beneficial bacterial liquid, thereby enhancing the fermentation effect of the feed and the nutrient absorption of the animals.

[0089] The pitch h of the spiral flip type stirring head 105 is 7 cm-15 cm; the appropriate pitch h design makes the spiral flip type stirring head 105 more uniform during the stirring process, ensuring the uniform distribution of the components of the feed.

[0090] The barrel 8 is designed as a trapezoidal italic body, and the bottom diameter D of the barrel 8 is greater than or equal to the cross-sectional diameter d of the spiral flip type stirring head 105, and the difference between the bottom diameter D and the cross-sectional diameter d does not exceed 10 cm. The barrel adopts a trapezoidal italic design, and the reasonable ratio between the bottom diameter setting and the cross-sectional diameter of the spiral flip type stirring head (the difference does not exceed 10 cm) further enhances the stirring efficiency and avoids the situation where the feed adheres to the barrel wall or the bottom during the stirring process and is difficult to stir.

[0091] A method for stirring feed and heat preservation fermentation, comprising the following steps:

[0092] S1. Start the system for mixing feed and heat preservation and fermentation, open the cleaning unit 9 to automatically clean the equipment through the sprinkler pipe 902;

[0093] S2. After the bacterial liquid in the bacterial liquid storage barrel in the bacterial liquid constant temperature chamber reaches a suitable temperature, the feed barrel mobile vehicle containing the feed is pushed into the first feed barrel compartment 5, the stirring assembly 1 is started and the bacterial liquid is added to stir the feed;

[0094] S3. Push the stirred barrel mobile vehicle into the second barrel compartment 6 of the heat preservation fermentation box for heat preservation and fermentation; start the cleaning unit 9 equipment for automatic cleaning.

[0095] The more specific steps are as follows:

[0096] S1: Start the equipment and clean it

[0097] Before starting the system for mixing feed and keeping warm for fermentation, the staff checked whether all components were firmly connected, including the material barrel 8, the mixing component 1, etc., and ensured that the sprinkler pipe 902 was properly connected, and the water heater and the cleaning liquid storage device were in working condition.

[0098] The operator selects "cleaning mode" through the control box, starts the cleaning unit 9, and the sprinkler pipe 902 delivers heated cleaning liquid through the hot water inlet and sprays it to key parts such as the mixing chamber 4, the first barrel chamber 5, the spiral flip-type mixing head 105, and the power rotating shaft 104. The high-pressure water flow combined with the multi-angle nozzle of the sprinkler pipe 902 is used for comprehensive flushing to remove residual feed, bacterial liquid and other impurities. After cleaning is completed, the system starts the hot air blower 106, blows hot air through the fan installation slot, and quickly dries the cleaned parts. The sensor detects whether the surface of the equipment is clean. If there is any residue, the system will automatically perform a second cleaning.

[0099] S2: Feed mixing and bacterial liquid addition

[0100] In the bacterial liquid constant temperature room, the temperature of the bacterial liquid is heated to a set range (such as 30°C to 40°C) by the constant temperature heating component of the bacterial liquid constant 7. The control box monitors and displays the bacterial liquid temperature in real time. When the temperature reaches the set value, the system prompts that the bacterial liquid is available. Fix the barrel 8 filled with feed on the barrel mobile vehicle, and push the barrel into the first barrel cabin 5 through the barrel mobile vehicle to ensure that the barrel 8 is tightly connected to the mixing cabin 4 to form a mixing space. The barrel limit ring ensures that the barrel is in a stable position in the first barrel cabin to avoid shaking or displacement during mixing.

[0101] Start the stirring assembly 1, the first motor 101 drives the power rotating shaft 104, and drives the spiral flip stirring head 105 to evenly stir the feed in the barrel; the stirring speed and time are adjusted by the controller to optimize the stirring effect according to the characteristics of the feed. The system controls the bacterial liquid channel in the sprinkler pipe 902 to open, and sprays the preheated bacterial liquid into the barrel at a uniform flow rate to fully mix with the feed. The temperature sensor detects the temperature of the mixed material in real time to ensure that the material maintains a suitable fermentation temperature during the stirring process. After the stirring is completed, the system prompts the operator through sound effects or display screens that the mixture in the barrel 8 is ready for fermentation.

[0102] S3: The mobile vehicle is pushed into the heat preservation fermentation box

[0103] The operator pushes the barrel moving cart out of the first barrel compartment 5 and moves it to the second barrel compartment 6 of the insulated fermentation box, ensuring that the barrel is firmly pushed into the second barrel compartment 6. The size of the barrel limit ring and the push-pull panel fully matches the barrel to ensure the sealing and stability of the barrel.

[0104] The system starts the insulated fermentation box, and maintains a constant temperature (e.g., 35°C to 45°C) through the insulation cotton and temperature control device laid on the inner wall, providing a suitable fermentation environment. The temperature sensor in the barrel 8 is electrically connected to the controller in the control box to monitor the fermentation temperature in real time. When temperature deviation occurs during the fermentation process, the controller adjusts the hot air blower 106 in the fermentation box to ensure temperature stability.

[0105] After the fermentation process begins, the system starts the cleaning unit 9 again to perform a second cleaning of the mixing chamber 4, the first barrel chamber 5 and related components to prevent the residual bacterial liquid from corroding the equipment components or contaminating subsequent production. The cleaning unit 9 repeats the cleaning process according to the set program, spraying with high-pressure hot water and cleaning liquid, and quickly drying with a hot air blower. After the cleaning is completed, the system displays a "cleaning completed" prompt and the equipment enters the standby state.
