Short-chain fatty acids (C1-C14) and their derivatives (fatty acid salts and fatty acid glycerides) have the functions of improving growth performance and other nutritional effects, and are a powerful substitute for antibiotics. In addition, a large number of research results have shown that short-chain fatty acid glycerides have a good growth-promoting effect as a feed additive, but there are no reports on the research of short-chain fatty acid glycerides in feed.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. Start the vacuuming device. Since the other end of the suction chamber is closed, the suction chamber can only be evacuated from the central tube. Therefore, the pressure in the pipeline and the suction chamber is lower than the pressure in the sampling box. Under the action of negative pressure, if there is obvious moisture in the sampling box, the moisture begins to pass through the suction cup and enter the pipeline, and finally enters the suction chamber. Before starting the negative pressure operation on the suction chamber, the heating element needs to be started first. The heating element heats the heating tube. Therefore, when the moisture is pumped into the suction chamber, the water will make a sound when it encounters the heated outer wall of the heating tube. Since the sound sensor is close to the position of the pipeline, the sound sensor can receive the hissing sound made by the water encountering the outer wall of the heating tube. Therefore, as long as the water makes a sound after contacting the outer wall of the heating tube, it can be recognized by the sound sensor, and the first buzzer starts to make a sound. 2. Since water will evaporate when it hits the outer wall of the heating tube, a condensation plate is needed to condense the water vapor. The condensed water can drip from the condensation plate into the collection box. When the condensed water enters the collection box, the water sensor starts to trigger the second buzzer to sound, which proves that there is water vapor in the suction chamber; 3. When the rotating motor controls the rotating disk to rotate rapidly, the rotating disk drives the two sampling boxes to start orbiting. At the same time, there is a relative displacement between the transmission ring teeth and the transmission inner teeth. The transmission ring teeth begin to be driven by the transmission inner teeth and begin to rotate. The sampling box begins to rotate during the rotation process. During the rapid rotation of the sampling box, the granular material inside begins to be thrown. If the inside is moist, the moisture is thrown out and contacts the test paper. The test paper turns red after encountering water. After the rotating disk rotates for a period of time, the rotation speed of the rotating motor is reduced, and then the color sensor begins to identify the test paper on the sampling box passing through its position. If the test paper turns red, the display light can be turned on, which proves that the material in the sampling box is moist and needs to be dried. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is combined with Figure 1-4 This application is described in further detail. Embodiment 1

[0020] The present application example discloses a method for preparing a feed containing a short-chain fatty acid glyceride feed additive. Figure 1-Figure 4 The method for preparing a feed containing a short- and medium-chain fatty acid glyceride feed additive comprises the following steps: S1. Prepare materials: prepare protein source raw materials, fat source raw materials, sugar source raw materials, short-chain fatty acid glyceride feed additives and other additives according to the ratio; in this embodiment, the raw materials are composed of the following raw materials in parts by weight: 55-75 parts of carbohydrate source raw materials, 1-6 parts of conventional fat source raw materials, 20-30 parts of protein source raw materials, 0.05-1 parts of short-chain fatty acid glyceride, 0.5-1 parts of complex vitamins, 1-2 parts of complex mineral salts, 1-2 parts of calcium dihydrogen phosphate, 0.1-0.2 parts of antioxidants, and 0.1-0.5 parts of choline chloride; wherein the short-chain fatty acid glyceride is composed of the following components in parts by weight: 5-25 parts of butyric acid glyceride, 5-25 parts of propionic acid glyceride, 2-10 parts of valeric acid glyceride, 2-10 parts of caprylic acid glyceride, 2-10 parts of capric acid glyceride, 0.2-5 parts of lauric acid glyceride, 30-75 parts of bound glycerol, and 25-70 parts of free glycerol.

Inspection: Spot check the stored particles after drying to determine whether they are dried. If they are not dried, they need to go to the drying process for drying; if the drying is completed, they enter the packaging process; During the S4 drying process, detection is performed through a detection device; the detection device includes a sampling mechanism, a suction mechanism for suction detection of particles, and an adjustment mechanism for swinging detection of particles; first, the particulate material is randomly sampled by the sampling mechanism, and then the suction mechanism is used to start sucking the material. If there is obvious moisture in the particulate material, the moisture is extracted at this time and the presence of moisture in the particulate material can be identified. If the moisture is not extracted, the particles need to be swung. The shaking process can swing out a small amount of moisture compared to the extraction process, and whether the particles are completely dry can be re-detected, which can greatly ensure the accuracy of the particulate material drying detection.

[0022] The sampling mechanism includes a valve 2 connected to the storage device 1, a frame 3, a rotating disk 4 rotatably arranged on the frame 3, a plurality of sampling boxes 5 rotatably arranged on the rotating disk 4, a sealing cover 7 assembly for sealing the sampling box 5, and a rotating motor 6 for controlling the rotation of the rotating disk 4. The valve 2 is connected to the storage device 1 and the valve 2 in this embodiment can be a solenoid valve. The sampling box 5 rotates to a position facing the valve 2. The upper end of the sampling box 5 is opened and sealed by the sealing cover 7 assembly. The side wall of the sampling box 5 is porous to facilitate the water to be thrown out from the side wall of the sampling box 5. The sampling box 5 is cylindrical. The position of the rotational connection between the rotating disk 4 and the frame 3 is located at the rotating disk. At the center of the moving disk 4, the rotating motor 6 controls the rotation of the rotating disk 4. In the initial state, one of the sampling boxes 5 is located directly below the valve 2. When the valve 2 starts, the particulate material enters the sampling box 5; the sealing cover 7 assembly includes a sealing cover 7 rotatably arranged at the top opening of the sampling box 5 and a closed motor 8 for controlling the rotation of the sealing cover 7. The axis of rotation of the sealing cover 7 and the sampling box 5 is located on the symmetric plane of the sampling box 5. The output end of the closed motor 8 is fixedly connected to the end of the rotating shaft of the sealing cover 7. When the sealing cover 7 is in a horizontal state, the top of the sampling box 5 is in a closed state. When the sealing cover 7 is rotated to a vertical state, the top of the sampling box 5 is opened, and the particulate material can enter the sampling box 5.

[0023] Reference Figure 1-Figure 4The suction mechanism includes a suction pipe 9, a filter screen 10 for filtering water, an extraction component for sealing and extracting the suction pipe 9, and a judgment component for judging whether water flows out of the suction pipe 9 by sound. Both ends of the suction pipe 9 are opened and the suction pipe 9 is rotatably connected to the rotating disk 4. The filter screen 10 is arranged at one end of the suction pipe 9 and the sampling tube. The suction pipe 9 is located at the bottom of the sampling box 5. In this embodiment, the number of sampling boxes 5 is set to two or four, preferably two. The rotating disk 4 is provided with two symmetrically arranged mounting holes. The suction pipe 9 is rotatably connected to the inner wall of the mounting hole through a bearing. The rotating disk 4 is provided with There is an inner cavity, which includes multiple suction cavities 11 corresponding to the sampling tubes. The multiple suction cavities 11 are interconnected and intersect at the center of the rotating disk 4. The extraction component includes multiple pipes 12, suction cups 13 and a control part for controlling the elastic movement of the pipes 12. The multiple suction cavities 11 are all provided with multiple through holes 14. The pipes 12 are elastically arranged in the through holes 14. The top ends of the pipes 12 are fixedly connected to the suction cups 13, and the bottom ends of the pipes 12 extend into the suction cavities 11. The rotating disk 4 is provided with a central tube 15 at its center. One end of the central tube 15 intersects with the multiple suction cavities 11, and the other end of the central tube 15 is externally connected to a vacuum device 20.

[0024] In this embodiment, the air pump 20 can be any air pump, and because the center tube 15 will also rotate with the rotating disk 4, a hose is required to connect the air pump 20 to the center tube 15. The number of sampling tubes and suction chambers 11 is the same and both are two. The perforation 14 is used to connect the suction tube 9 and the pipeline 12, and the perforation 14 is vertically arranged. The bottom end of the suction tube 9 is also located in the perforation 14. The control unit includes a first electric push rod 16, an electromagnet 17, a connecting ring 18 and a spring 19. The connecting ring 18 is fixed to the part of the pipeline 12 located in the suction chamber 11. The first electric push rod 16 is fixed in the suction chamber 11. One end of the spring 19 is connected to the connecting ring 18. The upper end is fixedly connected, and the other end is fixedly connected to the inner wall of the suction chamber 11. The electromagnet 17 is used to adsorb the outer edge of the connecting ring 18, and the first electric push rod 16 controls the movement of the electromagnet 17; because in the initial state, the sampling box 5 corresponds to the pipeline 12, even after the rotating disk 4 rotates 180°, the material taking work of the two sampling boxes 5 can be realized. At this time, the two sampling boxes 5 can still correspond to the two pipelines 12 respectively, and the suction cup 13 is made of rubber material, and the area of ​​the suction cup 13 is larger than the bottom end of the suction tube 9. In order to make the suction cup 13 and the suction tube 9 fit more closely, the bottom end of the suction tube 9 is provided with an outer edge, and the outer peripheral wall of the suction cup 13 can fit tightly with the outer edge.

[0025] First, it is necessary to sample the two sampling boxes 5. When the sampling work is completed, the suction cup 13 is located in the perforation 14 at the initial position, and the spring 19 is in a stretched state. When it is necessary to connect the suction cup 13 and the suction tube 9, the electromagnet 17 is powered off. Under the action of the spring 19 restoring its original shape, the pipe 12 and the suction cup 13 both impact toward the bottom end of the suction tube 9, and the suction cup 13 and the outer edge of the bottom end of the suction tube 9 are tightly fitted together. In this embodiment, the suction cup 13 can also be separated from the suction tube 9 by pulling the first electric push rod 16, and the vacuum device 20 is started. Since the other end of the suction chamber 11 is closed, the suction chamber 11 can only be evacuated from the center tube 15. Therefore, the pressure in the pipe 12 and the suction chamber 11 is less than the pressure in the sampling box 5. Under the action of negative pressure, if there is obvious moisture in the sampling box 5, the moisture begins to pass through the suction cup 13 and enters the pipe 12, and finally enters the suction chamber 11.

[0026] Reference Figure 1-Figure 4 The judging component includes a plurality of heating tubes 21, a plurality of heating elements 22 arranged in the heating tubes 21, a plurality of sound sensors and a plurality of first buzzers 23. The heating tubes 21 are arranged in the corresponding suction chambers 11. The sound sensors are arranged near the pipes 12 and facing the heating tubes 21. The number of the heating tubes 21 corresponds to the number of the suction chambers 11. The heating elements 22 are arranged as electric heating wires. The electric heating wires start to heat the heating tubes 21. The heating tubes 21 are made of materials with high thermal conductivity. In this embodiment, in order to ensure that the water entering the suction chamber 11 can be evaporated, the heating elements 22 can heat the outer wall of the heating tubes 21 to 100 degrees Celsius. When the negative pressure operation of the suction chamber 11 is started, Before that, it is necessary to start the heating element 22, and the heating element 22 heats the heating tube 21. Therefore, when the water is pumped into the suction chamber 11, the water will make a sound when it encounters the heated outer wall of the heating tube 21. Since the sound sensor is close to the position of the pipe 12, the sound sensor can receive the hissing sound made by the water encountering the outer wall of the heating tube 21. The sound sensor and the first buzzer 23 are controlled and connected through the PLC controller. Therefore, as long as the water makes a sound after contacting the outer wall of the heating tube 21, it can be recognized by the sound sensor, and the first buzzer 23 starts to make a sound. In this embodiment, it can be set that only after both first buzzers 23 make a sound will the detection process of the adjustment mechanism be entered.

[0027] In order to improve the accuracy of detection, a condensation component is also provided at the top of the central tube 15, and the condensation component includes a condensation plate 24, a collection box 25, a water sensor 27 and a second buzzer 26. The condensation plate 24 is fixed in the central tube 15, and the collection box 25 is located below the condensation plate 24. The water sensor 27 is arranged in the collection box 25. The water sensor 27 is electrically connected to the second buzzer 26. The water sensor 27 and the second buzzer 26 are connected by a PLC controller. The sound judgment and whether condensed water is generated are used to judge, which greatly improves the accuracy of detection. In this embodiment, the condensation plate 24 needs to be smaller than the cross-sectional size of the central tube 15 to ensure that the central tube 15 and the exhaust device 20 can normally perform negative pressure operation on the suction chamber 11. ; Since water will evaporate after encountering the outer wall of the heating tube 21, the condensation plate 24 is needed to condense the water vapor. Of course, it is necessary to limit the heating behavior of the heating tube 21 so that it will not affect the moisture in the sampling box 5 and will not affect the normal operation of the condensation plate 24. When the water vapor condenses on the condensation plate 24, the condensation plate 24 can be set at an angle, and the condensed water can drip from the condensation plate 24 into the collection box 25. When the condensed water enters the collection box 25, the water sensor 27 starts to trigger the second buzzer 26 to make a sound, which proves that there is water vapor in the suction chamber 11. Of course, before this detection, it is necessary to ensure that the suction chamber 11 is in a dry state to prevent external factors from affecting the detection result of whether there is moisture in the sampling box 5.

[0028] Reference Figure 1-Figure 4When there is no water vapor or no sound between the water and the heating tube 21, the adjustment mechanism needs to start working. It is necessary to disconnect the connection between the suction cup 13 and the suction tube 9 first to ensure that the suction tube 9 and the sampling box 5 can rotate normally on the rotating disk 4. The adjustment mechanism includes a test paper 28 wound outside the sampling box 5, a winding assembly for winding the test paper 28, a color sensor 32, a display light 33 electrically connected to the color sensor 32, and a transmission assembly for realizing the rotation and revolution of the sampling box 5. The test paper 28 is movably arranged outside the sampling box 5, the color sensor 32 is arranged on the frame 3 and the color sensor 32 is facing the direction of the sampling box 5. The test paper 28 uses cobaltous chloride test paper 28, and the winding assembly includes two winding boxes 30, two winding rollers 29, multiple winding ropes 31 and multiple A guide roller is provided, and the length direction of the guide roller is arranged along the length direction of the sampling box 5. Multiple guide rollers are evenly spaced along the peripheral wall of the sampling box 5. The guide rollers are used to realize winding the test paper 28 on the outer wall of the sampling box 5. Two winding boxes 30 are arranged at two mutually close positions of the sampling box 5. The winding box 30 is provided with an opening for the test paper 28 to pass through. The winding roller 29 is rotatably arranged in the winding box 30. The axial direction of the winding roller 29 is arranged along the length direction of the sampling box 5. Multiple winding ropes 31 are arranged at intervals from multiple test papers 28. The area of ​​the test paper 28 is larger than the peripheral wall area of ​​the sampling box 5. Therefore, it can ensure that the test paper 28 covers the outer wall of the sampling box 5 to the maximum extent. The winding ropes 31 located at both ends are fixedly connected to the peripheral walls of the two winding rollers 29 respectively, and the two winding motors respectively control the rotation of the two winding motors.

[0029] Reference Figure 1-Figure 4 The transmission assembly includes a plurality of transmission ring teeth 34 and transmission inner teeth 35. The transmission ring teeth 34 are fixed to the outer wall of the suction pipe 9, and the transmission inner teeth 35 are fixed to the frame 3. The plurality of transmission ring teeth 34 are meshed and connected with the transmission inner teeth 35 and the plurality of transmission ring teeth 34 are located inside the transmission inner teeth 35. The number of transmission ring teeth 34 is set to two. When the rotating motor 6 controls the rotating disk 4 to rotate rapidly, the rotating disk 4 drives the two sampling boxes 5 to start orbiting. At the same time, there is a relative displacement between the transmission ring teeth 34 and the transmission inner teeth 35. The transmission ring teeth 34 begin to be driven by the transmission inner teeth 35 and begin to rotate. The sampling box 5 begins to rotate when it starts to rotate. During the rapid rotation of the sampling box 5, the granular material inside it begins to be shaken. If the inside is moist, the moisture is shaken out and comes into contact with the test paper 28. The test paper 28 turns red after encountering water. After the rotating disk 4 rotates for a period of time, the rotation speed of the rotating motor 6 is reduced, and then the color sensor 32 begins to identify the test paper 28 on the sampling box 5 passing through its position. If the test paper 28 turns red, the display light 33 can be turned on, indicating that the material in the sampling box 5 is moist and needs to be dried. In addition, in the present application, the drying operation and the suction operation can control only one operation, or of course, both can work in sequence.

[0030] The implementation principle of the method for preparing feed containing short and medium-chain fatty acid glyceride feed additives in the embodiment of the present application is as follows: when the cover 7 is in a horizontal state, the top of the sampling box 5 is in a closed state, and when the cover 7 is rotated to a vertical state, the top of the sampling box 5 is opened, and the granular material can enter the sampling box 5. In the initial state, the sampling box 5 corresponds to the pipeline 12. Therefore, even after the rotating disk 4 rotates 180°, the material taking work of the two sampling boxes 5 can be realized. At this time, the two sampling boxes 5 can still correspond to the two pipelines 12 respectively. The suction cup 13 is made of rubber material, and the area of ​​the suction cup 13 is larger than the bottom end of the suction tube 9. In order to make the suction cup 13 fit more closely with the suction tube 9, the bottom end of the suction tube 9 is provided with an outer edge, and the outer peripheral wall of the suction cup 13 can fit tightly with the outer edge.

[0031] Start the vacuum device 20. Since the other end of the suction chamber 11 is closed, the suction chamber 11 can only be evacuated from the central tube 15. Therefore, the pressure in the pipe 12 and the suction chamber 11 is less than the pressure in the sampling box 5. Under the action of negative pressure, if there is obvious moisture in the sampling box 5, the moisture begins to pass through the suction cup 13 and enters the pipe 12, and finally enters the suction chamber 11. Before starting the negative pressure operation on the suction chamber 11, it is necessary to start the heating element 22 first. The heating element 22 heats the heating tube 21. Therefore, when the moisture is pumped into the suction chamber 11, the water will make a sound when it encounters the heated outer wall of the heating tube 21. Since the sound sensor is close to the position of the pipe 12, the sound sensor can receive the hissing sound made by the water encountering the outer wall of the heating tube 21. Therefore, as long as the water makes a sound after contacting the outer wall of the heating tube 21, it can be recognized by the sound sensor, and the first buzzer 23 starts to make a sound. Since water will evaporate when it encounters the outer wall of the heating tube 21, the condensation plate 24 is needed to condense the water vapor. The condensed water can drip from the condensation plate 24 into the collection box 25. When the condensed water enters the collection box 25, the water sensor 27 starts to trigger the second buzzer 26 to make a sound, which proves that there is water vapor in the suction chamber 11.

[0032] When the rotating motor 6 controls the rotating disk 4 to rotate rapidly, the rotating disk 4 drives the two sampling boxes 5 to start orbiting. At the same time, there is a relative displacement between the transmission ring gear 34 and the transmission internal gear 35. The transmission ring gear 34 begins to be driven by the transmission internal gear 35 and starts to rotate. The sampling box 5 starts to rotate when it starts to rotate. During the rapid rotation of the sampling box 5, the granular material inside it begins to be thrown. If the inside is moist, the moisture is thrown out and contacts the test paper 28. The test paper 28 turns red after encountering water. After the rotating disk 4 rotates for a period of time, the rotation speed of the rotating motor 6 is reduced, and then the color sensor 32 begins to identify the test paper 28 on the sampling box 5 passing through its position. If the test paper 28 turns red, the display light 33 can be turned on, which proves that the material in the sampling box 5 is moist and needs to be dried. Embodiment 2

[0033] The present application example discloses a feed containing a short-chain fatty acid glyceride feed additive. Figure 1 The feed containing short and medium-chain fatty acid glyceride feed additive is composed of the following raw materials in parts by mass: 55-75 parts of carbohydrate source raw materials, 1-6 parts of conventional fat source raw materials, 20-30 parts of protein source raw materials, 0.05-1 parts of short and medium-chain fatty acid glycerides, 0.5-1 parts of complex vitamins, 1-2 parts of complex mineral salts, 1-2 parts of calcium dihydrogen phosphate, 0.1-0.2 parts of antioxidants, and 0.1-0.5 parts of choline chloride; wherein the short and medium-chain fatty acid glycerides are composed of the following components in parts by mass: 5-25 parts of butyric acid glyceride, 5-25 parts of propionic acid glyceride, 2-10 parts of valeric acid glyceride, 2-10 parts of caprylic acid glyceride, 2-10 parts of capric acid glyceride, 0.2-5 parts of lauric acid glyceride, 30-75 parts of bound glycerol, and 25-70 parts of free glycerol. Since short- and medium-chain fatty acid glycerides are added to the feed, the short- and medium-chain fatty acid glycerides have the characteristics of no peculiar smell, no corrosion, no pollution, and no residue. They are stable after being mixed with acids, vitamins, and trace elements, and do not react with premixes and other nutrients in feeds. They can maintain stable performance within a pH range of 1-9. Since short- and medium-chain fatty acid glycerides are added to the feed, the feed has good palatability, a fast feeding speed, reduces the dissolution loss of feed in water, and a fast growth speed. The glycerol therein can be absorbed as energy, which is helpful for feed digestion and body growth. Since the raw materials used are all feed raw materials, they do not contain artificial pigments and chemical additives.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
