Description

Technical Field

[0001] The present invention relates to the technical field of feed processing equipment, and particularly relates to a method for preparing animal feed using citrus pulp residue and a device for preparing animal feed. Background Art

[0002] As an economically important crop widely cultivated globally, a large amount of by-products - citrus pulp residue - are generated during the deep processing of citrus, such as in juice, canned food, etc. This type of by-product mainly consists of fruit pulp, fruit kernels, fruit peels, and defective fruits selected during processing. Citrus pulp residue is rich in cellulose, hemicellulose, pectin, and various minerals, and has the natural advantage of being converted into feed raw materials. It can not only solve the environmental protection problem of agricultural product processing waste, but also broaden the source of feed raw materials, reduce the raw material cost of feed production, and has significant economic and ecological value. Currently, in the production process of preparing feed from citrus pulp residue, operations such as quantitative feeding, crushing, stirring, enzymatic reaction, drying, granulation, and cooling are required. However, in the prior art, there is a lack of equipment for integrated one-piece processes. For example, in the patent application number: CN201710848852.X, a device for making round granular feed from citrus pulp residue, the defect of this device is that although it involves the core processes of crushing and granulating citrus pulp residue, it does not achieve the full-process integration of feeding, crushing, stirring, enzymatic reaction, drying, granulation, and cooling. Each processing unit is independent, and material transfer needs to be achieved through manual or additional transfer equipment, which not only leads to poor production continuity, but also easily causes material loss and dust pollution, and cannot achieve the联动 control of process parameters, restricting the standardized production level.

[0003] In summary, in the prior art, there is a lack of a full-process integrated technology for preparing citrus pulp residue feed. Through functional modules such as feeding, crushing, collaborative stirring, efficient enzymatic reaction, energy-saving drying, standardized granulation, and directional cooling, the standardized and efficient production of citrus pulp residue feed can be achieved, promoting the规模化 development of the resource utilization of citrus pulp residue. Summary of the Invention

[0023] See Figures 1-19 As shown, an apparatus for preparing animal feed using citrus pomace according to the present invention includes: a support frame 1, and further includes: The crushing tank 2 is provided with an inlet end I21, and a crushing component 3 is provided inside the crushing tank 2. A vibration filter component 4 is provided directly below the crushing component 3. The crushing tank 2 is mounted on a support frame 1. The chain elevator 5 has its inlet end II 51 connected to the outlet end I 22 of the crushing tank 2; The preparation tank 6 has a sandwich structure 61, and a heating component 62 and an ultrasonic vibrator 63 are provided inside the sandwich 61. A stirring component 64 is provided inside the preparation tank 6, and a reaction enzyme inlet 65 is provided on the preparation tank 6. The inlet end III 66 of the preparation tank 6 is connected to the outlet end II 52 of the chain elevator 5, and the preparation tank 6 is mounted on the support frame 1. The drying conveyor box 7 is equipped with an auger assembly 71, which is connected to the hot air conveyor 72. The inlet end IV 73 of the drying conveyor box 7 is connected to the outlet end III 67 of the preparation tank 6. The granulation tank 8 is provided with a granulation assembly 81. The inlet end V82 of the granulation tank 8 is connected to the outlet end IV74 of the drying conveyor box 7, and the granulation tank 8 is mounted on the support frame 1. Cooling tank 9, which is equipped with a cold air assembly 91, and the inlet end VI 92 of cooling tank 9 is connected to the outlet end V 83 of granulation tank 8; A temperature sensor 101 is installed inside the preparation tank 6. The temperature sensor 101 is connected to the data processing module of the control module 102 installed on the preparation tank 6. The data processing module is electrically connected to the temperature control module. The temperature control module is electrically connected to the heating component 62. The preparation tank 6 is equipped with a solenoid valve 103, and the output part of the stirring assembly 64 is equipped with a torque sensor 104. The torque sensor 104 is connected to the data processing module of the control module 102, the data processing module is electrically connected to the solenoid valve control module, and the solenoid valve control module is electrically connected to the solenoid valve 103.

[0024] Working principle: S1. The operator puts the citrus residue into the crushing tank 2 through the inlet end I21. The internal crushing component 3 crushes the citrus residue into uniform fine particles, which facilitates the subsequent enzymatic hydrolysis reaction and granulation. After crushing, the material is screened by the vibrating filter component 4. Unqualified large particles are intercepted and wait for secondary crushing. Qualified particles are discharged from the outlet end I22 and fall into the inlet end II51 of the chain elevator 5 below. S2. Qualified particles are fed into the inlet end III66 of the preparation tank 6 through the outlet end II52 of the chain elevator 5. S3. The operator adds the reaction enzyme (such as compound cellulase) to the feed inlet of the preparation tank 6, starts the heating component 62 and ultrasonic vibrator 63 in the jacket structure 61 to provide a suitable preparation environment, and continuously stirs the material and enzyme solution through the stirring component 64 to make the material and enzyme solution fully mixed. During this process, the temperature sensor 101 monitors the temperature inside the preparation tank 6 in real time and feeds the data back to the data processing module of the control module 102. Then, the temperature control module sends a signal to the heating component 62 to adjust the temperature of the preparation tank 6 in real time, ensuring that the preparation tank 6 is always within the most suitable temperature range for preparation (usually 45-60℃). In addition, the ultrasonic cavitation effect of the ultrasonic vibrator 63 is used to destroy the fiber structure of citrus pomace and improve the contact efficiency between the reaction enzyme and the substrate. S4. The torque sensor 104 monitors the operating torque of the stirring assembly 64 in real time and sends a signal to the data processing module of the control module 102. After the data processing module processes the data, when the torque value is detected to be within the preset range and remains stable within the range, the data processing module sends a command to the solenoid valve control module, which controls the solenoid valve 103 to open, and the prepared material enters the inlet end IV73 from the outlet end III67. S5. The enzymatically hydrolyzed material enters the drying conveyor box 7. While the screw conveyor assembly 71 propels the material, hot air is introduced in conjunction with the hot air conveyor 72 to realize the material is conveyed and dried at the same time. The dried material enters the inlet end V82 from the outlet end IV74. S6. The dried material enters the pelleting tank 8. The operator starts the pelleting component 81, which presses the material into high-density pellet feed. The pelleted feed enters the inlet VI92 from the outlet V83. S7. Cold air is delivered to the cooling tank 9 through the cold air assembly 91 to quickly cool the feed entering the cooling tank 9, ensuring the hardness and stability of the pellets, and finally obtaining the finished feed.

[0025] In practical use, the ultrasonic vibrator 63 utilizes the ultrasonic cavitation effect to disrupt the fiber structure of citrus pomace, thereby improving the contact efficiency between the reaction enzyme and the substrate. At the same time, the ultrasonic vibrator 63 can prevent the synthesized viscous material from sticking to the inner wall of the preparation tank 6.

[0026] ② In actual use, both the temperature sensor 101 and the torque sensor 104 can be commercially available products or existing patents. The control module 102 can be an STM32H743 microprocessor, etc., and the control module 102 can communicate with the ECU controller through a 4G / 5G network to realize remote monitoring of real-time data.

[0027] ③ In actual use, support frame 1 provides stable support for the device.

[0028] In summary, this device integrates functions such as crushing, preparation, drying, granulation, and cooling to meet the needs of continuous citrus pomace feed preparation. The crushing tank 2 can crush the citrus pomace to a suitable size, reducing the stirring time in the subsequent preparation tank 6, and allowing the finer particles to facilitate better contact between the citrus pomace and the reaction enzymes. The drying and conveying are achieved simultaneously through the drying conveyor box 7. The integrated drying and conveying setup reduces the footprint of multiple devices and saves preparation time. The pellets are fed into the pelleting tank 8 for pelleting and then cooled by the cooling tank 9, ultimately resulting in feed pellets that meet the standards and are easy to transport. The overall layout is compact and stable.

[0029] As described above, the structure of the crushing component 3 includes: The crushing roller assembly consists of a left crushing roller 31 and a right crushing roller 32, which are rotatably installed directly below the inlet end I21 of the crushing tank 2 and are arranged opposite to each other. Inclined guide plates 211 are provided on both sides of the inlet end I21. The left gear 33 is located outside the crushing tank 2 and is mounted on the rotating shaft of the left crushing roller 31; The right gear 34 is located outside the crushing tank 2 and is mounted on the rotating shaft of the right crushing roller 32. The right gear 34 meshes with the left gear 33. The drive motor I35 is mounted on the support frame 1, and the output end of the drive motor I35 is connected to the rotating shaft of the right crushing roller 32.

[0030] Working principle: The operator first starts the drive motor I35 through the power supply. After the drive motor I35 starts, the output end drives the rotating shaft of the right crushing roller 32 to rotate. At this time, the right gear 34 installed on the rotating shaft of the right crushing roller 32 rotates. Through mutual meshing, the right gear 34 drives the left gear 33 to rotate. The left gear 33 is installed on the rotating shaft of the left crushing roller 31. Finally, the left crushing roller 31 rotates synchronously in the opposite direction. The operator feeds the citrus pulp into the inlet I21. Guided by the inclined guide plates 211 on both sides, it slides between the left crushing roller 31 and the right crushing roller 32. The left crushing roller 31 and the right crushing roller 32 rotate in opposite directions to generate squeezing and shearing forces, crushing the citrus pulp and other materials. The crushed material falls into the crushing tank 2, waiting for subsequent operations. In actual use, the crushing roller assembly is connected to the crushing tank 2 through bearings. Since the left gear 33 and the right gear 34 are located on the outside of the crushing tank 2, the addition of lubricating oil to the gear meshing point regularly will not affect the citrus residue inside the crushing tank 2, thus preventing oil from contaminating the citrus residue.

[0031] As described above, the side of the crushing tank 2 is vertically provided with two sets of sliding grooves 23, and an installation plate 24 is protruding directly below the sliding grooves 23. The structure of the vibration filtering component 4 includes: The bottom of the bouncing bar 41 is connected to the mounting plate 24 via a spring 42, and the bottom of the bouncing bar 41 is provided with a movable groove 43; The guide post 44 is sleeved inside the spring 42, and the guide post 44 is adapted to the movable groove 43; The filter plate assembly 45 consists of two vertically distributed sets, which are inclinedly arranged inside the crushing tank 2. The filter plate assembly 45 is located directly below the crushing component 3. The lower end of the filter plate assembly 45 is hinged to the inner wall of the crushing tank 2, and the upper end of the filter plate assembly 45 passes through the slide groove 23 and is connected to the spring rod 41. A drive motor II 46 is mounted on the support frame 1, and the output end of the drive motor II 46 is connected to the striking block 47. The top of the bouncing rod 41 is located on the movement trajectory of the striking block 47.

[0032] Working principle: The operator first starts the drive motor II 46 via power supply. The drive motor II 46 drives the striking block 47 to perform a circular motion, causing the striking block 47 to continuously strike the top of the bouncing rod 41 (e.g., Figure 19 As shown in the figure (the red line represents the position comparison between the displacement and the position before displacement), because the bouncing rod 41 is connected to the mounting plate 24 through the spring 42, the bouncing rod 41 will bounce up and down along the guide post 44 after being hit. At this time, the bouncing rod 41 is connected to the high end of the filter plate assembly 45 through the slide groove 23, and the bouncing force is transmitted to the filter plate assembly 45, causing it to vibrate up and down around the low hinge point as the axis. The crushed citrus pulp falls into the inclined filter plate assembly 45. During the vibration process, the material that meets the particle size requirements falls through the filter holes, while the large particles slide to the bottom and accumulate, waiting to be removed and crushed again. At the same time, the filter plate assembly 45 actively vibrates back and forth, which can prevent the material from clogging the filter holes.

[0033] Among them, ① because the bottom of the bouncing rod 41 has a movable groove 43, when the striking block 47 hits the top of the bouncing rod 41, the bouncing rod 41 will slide up and down along the guide post 44. The movable groove 43 provides space for the guide post 44 to move vertically, preventing the bouncing rod 41 from shifting or tilting to the left or right; at the same time, during the extension and retraction process, the spring 42 will be restricted from radial deformation by the guide post 44, avoiding the spring 42 from twisting or misaligning.

[0034] ② In actual use, there are two sets of filter plates 45 arranged vertically. The upper and lower sets can be designed with different pore sizes. The upper filter plate has a larger pore size and the lower filter plate has a smaller pore size. The crushed material first passes through the upper coarse filter to separate large particles, and then passes through the lower fine filter to obtain fine particles that meet the requirements of subsequent processing. ③ In actual use, the side of the crushing tank 2 opposite to the filter plate group 45 is provided with an opening and closing door 48 with transparent glass. The operator can observe the filtration situation through the transparent glass and can deal with the accumulated material on the filter plate group 45 at any time by opening the opening and closing door 48 with transparent glass.

[0035] ④ In actual use, a plastic film can be attached to the chute 23 to prevent external pollutants from entering the tank. At the same time, anti-collision pads are installed on the upper and lower inner walls of the chute 23 to reduce wear caused by reciprocating motion.

[0036] ⑤ In actual use, the part where the top of the bouncing rod 41 contacts the striking block 47 is a spherical structure, which realizes point contact and rolling.

[0037] In the above scheme, the sandwich structure 61 is divided into an arc-shaped region 611 and a rectangular region 612, and a heat insulation layer is provided between the arc-shaped region 611 and the rectangular region 612. The heating component 62 is located in the arc-shaped area 611, the ultrasonic vibrator 63 is installed in the rectangular area 612, and the rectangular area 612 is provided with an opening and closing door 613 on the side. The structure of the stirring assembly 64 includes: A drive motor Ⅲ641 is installed in the preparation tank 6, and the rotating shaft of the drive motor Ⅲ641 is installed in the preparation tank 6 through a bearing. The torque sensor 104 is installed on the drive shaft. The vertical X-shaped stirring blades 642 are in two sets and are installed on the upper and lower halves of the rotating shaft; A transverse three-bladed stirring blade 643 is installed in the middle of the drive shaft, and a ring 644 is provided on the outer ring of the three-bladed stirring blade 643.

[0038] Working principle: The operator turns on the heating component 62 in the arc-shaped area 611, sets the target reaction temperature (usually 45-60℃), adds the reaction enzyme (such as compound cellulase) into the preparation tank 6 through the reaction enzyme inlet 65, and starts the drive motor III 641 through the external power supply. The drive motor III 641 drives the stirring component 64 to run and turns on the ultrasonic vibrator 63 in the rectangular area 612. During the mixing process, the motor drives the transmission shaft, and all the blades rotate synchronously. The upper X-shaped stirring blades 642 push the material (the mixture of crushed citrus pulp and reaction enzymes) downwards, while the lower X-shaped stirring blades 642 push the material upwards, so that the mixture forms an axial circulation, preventing bottom sedimentation and top floating, and making the mixing more thorough. Under the axial circulation action of the X-shaped stirring blades 642, the material is continuously transported to the central area of ​​the preparation tank 6. The high-speed rotating transverse three-bladed stirring blades 643, in conjunction with the outer ring 644, subject the material to tremendous mechanical shearing, compression, and tearing when it is forced to pass through this tiny gap. This effectively breaks down long fibers, crushes pectin clumps, and disperses solid particles in fibrous materials such as citrus pomace, ensuring uniform contact between the citrus pomace and the enzyme, and increasing the enzymatic hydrolysis rate. In actual use, the torque sensor 104 collects stirring resistance data in real time and judges the change in material viscosity by the data change. For example, the more complete the reaction, the lower the viscosity and the more stable the torque value. When the value displayed by the torque sensor 104 is stable, it is determined that the material reaction is complete. The data processing module sends a command to the solenoid valve control module, which controls the solenoid valve 103 to open. The prepared material enters the inlet end IV73 from the outlet end III67.

[0039] ② In actual use, the temperature sensor 101 monitors the temperature inside the preparation tank 6 in real time and feeds the data back to the data processing module of the control module 102. Then, the temperature control module sends a signal to the heating component 62 to adjust the temperature of the preparation tank 6 in real time, ensuring that the preparation tank 6 is always in the most suitable temperature range for preparation (usually 45-60℃). ③ In actual use, heating element 62 is preferably selected as heating wire. The installation and operation of heating wire are well known in the field and will not be described in detail here.

[0040] ④ A heat insulation layer is provided between the arc-shaped area 611 and the rectangular area 612 to prevent high temperature from affecting the operation of the ultrasonic vibrator 63, and the opening and closing door 613 makes it convenient for operators to inspect or replace the ultrasonic vibrator 63 at any time.

[0041] ⑤ In practical use, the ultrasonic vibrator 63 can be a commercially available product or an existing patent. Ultrasonic vibration can accelerate the collision frequency between enzyme molecules and material fibers, reduce the activation energy of the reaction, and make the enzymatic hydrolysis reaction faster and more complete. At the same time, the high-frequency vibration will act on the inner wall of the preparation tank 6 to prevent the material from adhering to the tank wall and the stirring blades.

[0042] In the above scheme, a plurality of air outlets 75 are provided directly above the drying conveyor box 7; The drive motor Ⅳ76 is mounted on the support frame 1, and the output end of the drive motor Ⅳ76 is provided with gear Ⅰ761; The structure of the auger assembly 71 includes: A hollow rotating shaft 711 is provided with several air outlets 712, and the hollow rotating shaft 711 is connected to the air outlet pipe 721 of the hot air conveyor 72 through bearings. The hollow rotating shaft 711 is provided with spiral blades 713, and a gear II 714 is installed on the outside of the hollow rotating shaft 711 protruding from the drying conveyor box 7. The gear II 714 meshes with the gear I 761. The lateral length of the hollow rotating shaft 711 is adapted to the length of the drying conveyor box 7.

[0043] Working principle: The operator first starts the hot air conveyor 72. After the hot air temperature reaches the set value, hot air is continuously conveyed to the hollow rotating shaft 711 through the air outlet pipe 721. Then, the drive motor IV 76 is started by the external power supply. The gear I 761 of the drive motor IV 76 rotates. The gear I 761 meshing with the gear II 714 rotates. The gear II 714 drives the hollow rotating shaft 711 to rotate. The enzymatically hydrolyzed material (enzymatically hydrolyzed citrus pomace) enters the drying conveyor box 7. The spiral blades 713 push the material forward at a uniform speed, while the air outlet 712 of the hollow rotating shaft 711 continuously blows out hot air. During the conveying process, the material comes into full contact with the hot air blown out by the hollow rotating shaft 711 to achieve drying, and the moisture is discharged through the upper air outlet 75. The dried material falls from the outlet end IV74 of the drying conveyor box 7 into the inlet end V82 of the granulation tank 8, waiting for subsequent granulation operations.

[0044] Among them, ① the dried humid and hot gas generally flows upward. Because the evaporation of water in the humid and hot gas will reduce the mass per unit volume, the density is less than that of the dry and cold air. The less dense humid and hot gas will be subject to upward buoyancy in the denser cold air, and will naturally flow upward and be discharged from the outlet 75.

[0045] ② In actual use, the hot air conveyor 72 can be a commercially available product or an existing patent.

[0046] ③ In actual use, the air outlet pipe 721 of the air conveyor is fixed, while the hollow shaft 711 rotates. The bearing is positioned between the two, allowing the hollow shaft 711 to rotate freely while fixing the relative position of the air outlet pipe 721 and the hollow shaft 711, thus preventing the air outlet pipe 721 from being damaged by twisting with the hollow shaft 711. In addition, in actual use, components such as bearing end caps and sealing gaskets can be added to prevent hot air from leaking from the connection gap between the shaft and the pipe, while also preventing dust from entering the bearing.

[0047] ④ The spiral blades 713 are installed on the hollow rotating shaft 711. When the length of the hollow rotating shaft 711 matches the drying conveyor box 7, the spiral blades 713 can completely cover the lateral space of the drying conveyor box 7. After the material is fed in from the inlet end IV73, it will be smoothly pushed to the outlet end IV74 by the spiral blades 713 throughout the process, which meets the requirements of continuous production.

[0048] ⑤ In actual use, the enzymatically hydrolyzed material usually has a high moisture content. Direct pelletizing can lead to problems such as easy particle sticking, easy breakage after molding, and equipment blockage. After hot air drying in the drying conveyor box 7, the moisture content of the material is controlled within the range suitable for pelletizing (around 12%–15%). This moisture content ensures sufficient adhesion between the material particles without causing sticking due to excessive moisture or excessive brittleness that prevents molding due to excessive dryness.

[0049] As described above, the structure of the granulation component 81 includes: The granulation plate 811 is provided with a number of die holes 812, and the granulation plate 811 is located below the outlet end IV74 of the drying conveyor box 7. Telescopic electric cylinder 813 is mounted on support frame 1, and the output end of telescopic electric cylinder 813 is provided with pressure plate 814 that is adapted to the inner radius of granulation tank 8, and pressure plate 814 is located directly above granulation plate 811. A conical guide plate 815 is located directly below the granulation plate 811, and a discharge channel 816 is provided between the conical guide plate 815 and the granulation tank 8. A drive motor V 817 is provided inside the conical guide plate 815. The rotating blade 818 is connected to the output end of the drive motor V 817, and the rotating blade 818 is located directly below the pelletizing plate 811.

[0050] Working principle: When the dried material continues to fall above the granulation plate 811 and reaches the predetermined height, the operator turns off the drive motor IV76 and starts the drive motor V817 and the telescopic electric cylinder 813 through the external power supply. The telescopic electric cylinder 813 drives the pressure plate 814 to continuously squeeze the material. The material is squeezed through the die hole 812 of the granulation plate 811 to form a continuous columnar material. The drive motor V 817 drives the rotating blade 818 to rotate at high speed, cutting the columnar material squeezed out from the die hole 812 of the granulation plate 811 into particles of a set length. The cut particles are discharged from the granulation tank 8 through the discharge channel 816 between the conical guide plate 815 and the granulation tank 8 and fall into the cold air assembly 91, completing one round of granulation operation. At this point, reset the telescopic electric cylinder 813, turn off the drive motor V817, and start the drive motor Ⅳ76 to begin a new round of granulation.

[0051] Among them, ① in actual use, the telescopic electric cylinder 813 can be a commercially available product or an existing patent.

[0052] ② In actual use, the granulation plate 811 is placed directly inside the granulation tank 8 and supported by the annular bracket on the inner wall. By changing the size of the die hole 812 of the granulation plate 811, the electric cylinder pressure and the blade speed, granules of different sizes and hardness can be produced to adapt to various material properties.

[0053] ③ In actual use, the surface of the conical guide plate 815 is smooth (and can be polished), so the material is not easy to stick and accumulate, and the particles slide along the conical surface under the action of gravity, reducing the retention in the transition area and reducing the risk of clogging the discharge channel 816.

[0054] As described above, the structure of the cooling air assembly 91 includes: A partition 911 is provided with several through holes, and the partition 911 is located in the lower middle part of the cooling tank 9; Fan 912 is located at the bottom of cooling tank 9; An annular limiting block 913 is positioned directly above the fan 912, and a vent plate 914 is placed on the annular limiting block 913. The space between the vent plate 914 and the partition plate 911 is a cooling chamber 915, and a half-open door 916 is hinged to the side of the cooling chamber 915.

[0055] Working principle: To operate the equipment, open the refrigeration chamber 915 and half-open the door 916. Place sufficient cooling medium (such as dry ice) on the vent plate 914, close the half-open door 916, and ensure a seal. The fan 912 (low power) is started by an external power supply, and the temperature of the cooling chamber 915 is sent to the upper part of the cooling tank 9 through the partition 911. The cut particles are put into the cooling tank 9 from the inlet end VI92 and fall above the partition 911 to achieve cooling.

[0056] Specifically, ① in actual use, the fan 912 operates at low power, preventing the cool air from sinking and maintaining a consistently low-temperature environment in the upper part of the cooling tank 9. Simultaneously, in a weak airflow environment, the particles are not disturbed by strong winds and remain in a stable accumulation state, making them less prone to breakage or adhesion during the cooling process.

[0057] ② In actual use, the fan 912 can be inspected by opening the half-open door 916 and removing the vent plate 914 from the annular limit block 913.

[0058] ③ In actual use, the bottom of the cooling tank 9 is equipped with casters to facilitate the handling of the prepared granules by the operators.

[0059] In the above scheme, the inlet end VI92 of the cooling tank 9 is positioned opposite to the outlet end V83 of the granulation tank 8, and the area between the inlet end VI92 and the outlet end V83 is sealed by attaching a plastic film 10 to the outer wall.

[0060] Working principle: The plastic film 10 utilizes its own flexibility to tightly adhere to the outer wall of the inlet end VI92 of the cooling tank 9 and the outlet end V83 of the granulation tank 8, forming a closed transition channel to block the entry of external air and the leakage of internal particles and dust. Meanwhile, after one round of preparation is completed (operators can observe the accumulation through the transparent window on the side of the cooling tank 9), the operator can directly remove the plastic film 10, and the inlet end VI92 of the cooling tank 9 will be completely open, facilitating the operator to check the overall condition of the feed in batches and to accept the prepared feed inside the cooling tank 9. The plastic film 10 can be removed without tools; the operator can quickly remove it and directly contact the feed inside the cooling tank 9, facilitating sampling and testing, and observation of particle uniformity, hardness, etc.

[0061] Example 1: A method for preparing animal feed using citrus pomace, employing an apparatus for preparing animal feed using citrus pomace, comprising the following steps: B1. Before starting the operation, the operator first uses the outward wheel to align the cooling tank 9 with the outlet end V73 of the granulation tank 8 and installs it, and seals the area between the inlet end VI92 and the outlet end V83 by attaching a plastic film 10 to the outer wall. When the operation begins, the operator puts the citrus pulp into the crushing tank 2 through the inlet end I21. The internal crushing component 3 crushes the citrus pulp into uniform fine particles, which facilitates the subsequent enzymatic hydrolysis reaction and granulation. After crushing, the material is screened by the vibrating filter component 4. Unqualified large particles are intercepted and wait for secondary crushing. Qualified particles are discharged from the outlet end I22 and fall into the inlet end II51 of the chain elevator 5 below. B2. Qualified particles are fed into the inlet end III66 of the preparation tank 6 through the outlet end II52 of the chain elevator 5. B3. The operator adds the reaction enzyme (such as compound cellulase) to the feed inlet of the preparation tank 6, starts the heating component 62 and ultrasonic vibrator 63 in the jacket structure 61 to provide a suitable preparation environment, and continuously stirs the material and enzyme solution through the stirring component 64 to make the material and enzyme solution fully mixed. During this process, the temperature sensor 101 monitors the temperature inside the preparation tank 6 in real time and feeds the data back to the data processing module of the control module 102. Then, the temperature control module sends a signal to the heating component 62 to adjust the temperature of the preparation tank 6 in real time, ensuring that the preparation tank 6 is always within the most suitable temperature range for preparation (usually 45-60℃). In addition, the ultrasonic cavitation effect of the ultrasonic vibrator 63 is used to destroy the fiber structure of citrus pomace and improve the contact efficiency between the reaction enzyme and the substrate. B4. The torque sensor 104 monitors the operating torque of the stirring assembly 64 in real time and sends a signal to the data processing module of the control module 102. After the data processing module processes the data, when the torque value is detected to be within the preset range and remains stable within the range, the data processing module sends a command to the solenoid valve control module, which controls the solenoid valve 103 to open, and the prepared material enters the inlet end IV73 from the outlet end III67. B5. The enzymatically hydrolyzed material enters the drying conveyor box 7. While the screw conveyor assembly 71 propels the material, hot air is introduced in conjunction with the hot air conveyor 72 to achieve simultaneous conveying and drying of the material. After being dried by the hot air in the drying conveyor box 7, the moisture content of the material is controlled within the range suitable for pelletizing. This moisture content ensures sufficient adhesion between the material particles without causing them to stick together due to excessive moisture or become too brittle and unable to be formed due to excessive dryness. The dried material enters the inlet end V82 from the outlet end IV74. B6. After drying, the material enters the pelleting tank 8. The operator starts the pelleting component 81, which presses the material into high-density pellet feed. The pelleted feed enters the inlet VI 92 from the outlet V 83. B7. Cold air is delivered to the cooling tank 9 through the cold air component 91 to quickly cool the feed entering the cooling tank 9, ensuring the hardness and stability of the pellets, and finally obtaining the finished feed. After the preparation is completed, the operator can move the cooling tank 9 away through the casters to collect the feed in a unified manner. Then the cooling tank 9 is aligned with the preparation tank 8 to start a new round of preparation.

They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.
