Description

Technical Field

[0001] This invention belongs to the field of feed processing technology, and specifically discloses an animal feed dehumidification device. Background Technology

[0002] Feed is highly susceptible to moisture absorption and clumping during pelleting, cooling, and storage. Freshly pelleted feed pellets are at high temperatures and have a high moisture content; if not dehumidified promptly and effectively, they easily clump together. Simultaneously, feed absorbs moisture and clumps during storage due to the humid environment. Clumping not only severely affects subsequent screening, packaging, and transportation but also leads to mold growth and spoilage due to excessive moisture, shortening shelf life. Therefore, dehumidification and drying are essential steps in feed production and processing.

[0003] Currently, some technologies have been developed to address the problem of feed dehumidification. For example, Chinese patent CN102359743A discloses a dehumidification and drying device for a feed pellet mill cooler to reduce feed moisture content. This device includes a cooler with a dryer composed of heat pipes installed inside. The dryer at the bottom of the cooler heats the moisture in the feed, causing it to escape, and then it is drawn away by a fan. This solution can reduce the moisture content of the feed to some extent, but it still has the following shortcomings.

[0004] First, it cannot solve the problem of feed clumping. This device only dries feed through static heating, leaving the feed in a piled-up or static state inside the cooler, preventing the formation of clumps from being broken up. Hot air can only act on the surface of the clumps and cannot penetrate into the interior, resulting in the inability of moisture inside the clumps to escape effectively, leading to unsatisfactory drying results and even a phenomenon of "dry on the outside and wet on the inside".

[0005] Secondly, the drying efficiency is low and the uniformity is poor. Because the feed lacks movement or agitation within the cooler, the contact area between the hot air and the feed is limited, resulting in low heat transfer efficiency, long drying time, and high energy consumption. Simultaneously, the feed in different locations is heated unevenly during the stacking process, leading to poor drying consistency; some feed is over-dried while others remain damp, affecting the quality of the finished product.

[0006] To address the aforementioned problems, this invention provides an animal feed dehumidification device that integrates hot air drying with agglomeration and chopping functions. This device continuously chops and breaks up agglomerated feed during the drying process, ensuring that hot air fully contacts the interior of the agglomerates. This significantly improves drying efficiency and uniformity, effectively solving the drying problem caused by feed agglomeration. Summary of the Invention

[0007] The purpose of this invention is to solve the problems of existing feed clumps being difficult to dry, having low drying efficiency and poor uniformity, and lacking a linkage mechanism between clump treatment and drying in the background art. The invention proposes an animal feed dehumidification device, comprising a feed processing box, a sealing component on one side of the feed processing box, a drying air inlet component at one end of the feed processing box, an extension duct at one end of the drying air inlet component, and flat-nozzle air outlets installed on both sides of the extension duct. Both sets of flat-nozzle air outlets are fitted with protective filter shells. The end of the extension duct away from the drying air inlet component is connected to the inner wall of one end of the feed processing box. The feed processing box is connected to a transfer frame via an internal transverse mechanism. The transfer frame is connected to two cutting gates via a clumping and cutting lifting component above. The two cutting gates are used inside the feed processing box to cut the clumped feed, and both outer surfaces of the two cutting gates are provided with heat-conducting layering components that cooperate with the extension duct to transfer hot air.

[0008] During the reciprocating movement of the transverse mechanism, the drying air inlet assembly continuously delivers hot air to the extension air duct. The extension air duct blows hot air out of the feed processing box through the flat-nozzle air outlet. The two cutting gates cut the clumped feed through the clumping cutting lifting assembly and accelerate the circulation of hot air, thereby improving the dehumidification efficiency.

[0009] In the above scheme, the sealing component further includes a sealed door and two hydraulic opening and closing rods. The two hydraulic opening and closing rods are rotatably installed on both sides of the feed processing box. The telescopic ends of the two hydraulic opening and closing rods are connected to the sealed door through a rotating shaft. The lower end of the sealed door is rotatably engaged with the feed processing box.

[0010] In the above scheme, the drying air inlet assembly further includes a drying fan and a rectangular air duct. The rectangular air duct is installed inside one end of the feed processing box. The drying fan is connected to the rectangular air duct through an air inlet pipe at one end. The end of the rectangular air duct away from the air inlet pipe is connected to an extension air duct.

[0011] In the above scheme, the transverse movement mechanism further includes a lead screw and a slide rod. The lead screw is rotatably inserted inside one side of the feed processing box, and the slide rod is fixedly inserted inside the other side of the feed processing box. One end of the lead screw extends to the outside of the feed processing box and is connected to a drive assembly. Both the lead screw and the slide rod are provided with connecting sleeves. One of the connecting sleeves is threadedly engaged with the lead screw, and the other connecting sleeve is slidably engaged with the slide rod. The bottom sides of the moving frame are jointly supported above the two connecting sleeves.

[0012] In the above solution, the drive assembly further includes a bracket, which is fixedly installed on the outside of one end of the feed processing box, and a motor is installed above the bracket. The output end of the motor is connected to one end of the lead screw through a synchronous belt assembly.

[0013] In the above scheme, the agglomeration and slitting lifting assembly includes a protective shell and a hydraulic rod. The hydraulic rod is fixedly installed above the moving frame and near the middle. The protective shell is sleeved on the outside of the hydraulic rod and its bottom is connected to the upper surface of the moving frame. A position sensor is provided on one side of the hydraulic rod. A movable seat is fixedly installed at the telescopic end of the hydraulic rod. A locking pin is fixedly inserted inside the movable seat. Both ends of the locking pin are rotatably connected to the slitting gates on both sides through connecting rods. A slide rail is provided in the middle of the bottom of the extension duct. A slide block is slidably fitted below the slide rail. A connecting seat is provided at the lower end of the slide block. Vertical sliding slices are provided at equal intervals along the horizontal direction at the bottom of the connecting seat. The two sides of the connecting seat are rotatably engaged with the slitting gates on both sides through U-shaped rotating rods.

[0014] In the above scheme, the heat-conducting layering component further includes a plurality of guide vanes, which are distributed at equal intervals along the arc-shaped trajectory of the outer surface of the slitting gate. A plurality of guide sloping plates are arranged at equal intervals on one side of the plurality of guide vanes, and the plurality of guide sloping plates extend from the root of the guide vanes to the outer edge of the slitting gate.

[0015] In the above scheme, a temperature sensor is connected and installed on one side of the feed processing box, and a controller is fixedly installed on one side of the feed processing box near the temperature sensor. A feed pipe is connected and installed at the bottom of the feed processing box, and a feed valve is provided in the middle section of the feed pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention integrates hot air drying and agglomeration / crushing functions into the same feed processing box. During the reciprocating movement of the frame driven by the transverse mechanism, hot air is continuously delivered to the feed layer through the flat-nozzle air outlets on both sides of the extended air duct. At the same time, the two cutting gates, driven by the agglomeration / crushing lifting assembly, repeatedly and alternately cut the agglomerated feed, so that hot air drying and mechanical crushing work together.

[0018] During this process, the guide vanes and guide slant vanes on the surface of the cutting gate guide the hot air layer by layer, so that the hot air can fully penetrate into the internal gaps of the cut feed, avoiding the problem that the clumping core cannot be heated under static drying method, and effectively eliminating the phenomenon of dry outside and wet inside.

[0019] Meanwhile, the transverse mechanism drives the slitting gate to reciprocate, continuously pushing and loosening the feed layer. This significantly increases the contact area and frequency between hot air and feed particles, substantially shortening drying time, improving hot air utilization efficiency, and ensuring the consistency of feed drying within batches. The symmetrically arranged heat-conducting layering components on both sides of the slitting gate further distribute hot air evenly to different depths of the feed layer, avoiding localized overheating or insufficient drying, effectively ensuring the quality stability of the finished feed. Furthermore, the entire drying and slitting process is completed within a closed processing chamber, minimizing heat loss and further reducing energy consumption, making it suitable for the needs of continuous industrial feed production.

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0030] like Figures 1-7 The animal feed dehumidification device shown includes a feed processing box 1, which is a box structure with an internal cavity for holding feed to be dehumidified. A sealing component is installed on the upper side of the feed processing box 1 to open and close the feed inlet, keeping the box sealed during operation to prevent heat loss and the entry of external humid air. A drying air inlet component is installed at one end of the feed processing box 1 to generate and deliver heated dry air. One end of the drying air inlet component is connected to an extension duct 16. Both sides of the extension duct 16 are connected to flat-nozzle air outlets 26. The outlets of the flat-nozzle air outlets 26 are flat and narrow, used to generate a flat fan-shaped hot airflow, increasing the contact area between the hot air and the feed. Two sets of flat nozzles... All air outlet ducts 26 are fitted with protective filter shells 17. The protective filter shells 17 are mesh shell structures with mesh sizes smaller than the minimum particle size of feed particles. This is to prevent feed particles from clogging the air outlet and to ensure that hot air can pass through the mesh smoothly and be ejected. The end of the extension duct 16 away from the drying air inlet assembly is connected to the inner wall of one end of the feed processing box 1. The feed processing box 1 is connected to a transfer frame 8 through an internal transverse mechanism. The transfer frame 8 is connected to two cutting gates 19 through the clumping and cutting lifting assembly above. The two cutting gates 19 are used inside the feed processing box 1 to cut clumped feed. Both outer surfaces of the two cutting gates 19 are provided with heat-conducting layering components that cooperate with the extension duct 16 to transfer hot air.

[0031] like Figure 1 and Figure 2As shown, in this embodiment, the sealing assembly includes a sealed door 9 and two hydraulic opening and closing rods 12. The sealed door 9 is a plate-shaped structure adapted to the size of the feed processing box 1 inlet. Its lower end is rotatably engaged with the lower end of the feed processing box 1 inlet via a rotating shaft, so that the sealed door 9 can be flipped upward to close or flipped downward to open around the rotating shaft. The two hydraulic opening and closing rods 12 are respectively rotatably installed on both sides of the feed processing box 1. The telescopic ends of the two hydraulic opening and closing rods 12 are connected to the sealed door 9 via a rotating shaft. The lower end of the sealed door 9 is rotatably engaged with the feed processing box 1.

[0032] Specifically, the cylinder end of the hydraulic opening and closing rod 12 is rotatably connected to the two side walls of the feed processing box 1 via a pin. The telescopic ends of both hydraulic opening and closing rods 12 are connected to the two sides of the airtight door 9 via a rotating shaft. When the telescopic end of the hydraulic opening and closing rod 12 extends, it pushes the airtight door 9 to rotate upward around its lower end until the airtight door 9 is tightly fitted with the edge of the feed inlet of the feed processing box 1, thus achieving a sealed closure; when the telescopic end of the hydraulic opening and closing rod 12 retracts, it pulls the airtight door 9 downward to open.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the drying air intake assembly includes a drying fan 3 and a rectangular air duct 4. The drying fan 3 is a centrifugal hot air fan, whose air inlet is connected to an external air source. It is equipped with an electric heating element or heat exchanger inside to heat the intake air to a set temperature before outputting it. The rectangular air duct 4 is connected to the inside of one end of the feed processing box 1. The drying fan 3 is connected to the rectangular air duct 4 through the air inlet pipe 2 at one end. The end of the rectangular air duct 4 away from the air inlet pipe 2 is connected to the extension air duct 16.

[0034] Specifically, one end of the air inlet duct 2 is connected to the air outlet of the drying fan 3 via a flange, and the other end is connected to the air inlet of the rectangular air duct 4 via a flange. The air outlet of the rectangular air duct 4 is connected to the air inlet of the extension duct 16. The drying fan 3 heats the outside air to form hot air, which is then sent through the air inlet duct 2 into the rectangular air duct 4 for buffering and stabilization, and then into the extension duct 16. The hot air is then ejected from the flat-nozzle air outlets 26 on both sides of the extension duct 16, achieving uniform distribution and delivery of hot air. The heating temperature of the drying fan 3 is adjusted by the controller 11 based on the signal fed back by the temperature sensor 10.

[0035] like Figure 3 and Figure 5As shown, in this embodiment, the transverse movement mechanism includes a lead screw 7 and a slide rod 15. The slide rod 15 is a smooth cylindrical rod, arranged parallel to the lead screw 7. The lead screw 7 rotatably passes through one side of the feed processing box 1, and the slide rod 15 is fixedly passed through the other side of the feed processing box 1. One end of the lead screw 7 extends to the outside of the feed processing box 1, and the end is connected to a drive assembly. Both the lead screw 7 and the slide rod 15 are provided with connecting sleeves 23. One connecting sleeve 23 is threadedly engaged with the lead screw 7. Specifically, the connecting sleeve 23 located on the lead screw 7 has an internal thread that engages with the external thread of the lead screw 7, and the two form a threaded engagement. The other connecting sleeve 23 is slidably engaged with the slide rod 15. The bottom sides of the moving frame 8 are jointly supported above the two connecting sleeves 23.

[0036] Furthermore, the shift frame 8 is mounted between the lead screw 7 and the slide bar 15. The rotational motion is converted into the linear reciprocating motion of the shift frame 8 through the threaded transmission of the lead screw 7. The slide bar 15 plays a guiding and balancing role, preventing the shift frame 8 from deflecting during the movement.

[0037] like Figure 3 As shown, in this embodiment, the drive assembly includes a bracket, which is fixedly installed on the outside of one end of the feed processing box 1. A motor 13 is installed above the bracket. The output end of the motor 13 is connected to one end of the lead screw 7 through a synchronous belt assembly 14. The synchronous belt assembly 14 includes a driving synchronous pulley, a driven synchronous pulley, and a synchronous belt. The driving synchronous pulley is fixedly installed on the output shaft of the motor 13. The driven synchronous pulley is fixedly installed on the outside of the end of the lead screw 7 that extends to the outside of the feed processing box 1. The synchronous belt is tensioned and sleeved between the driving synchronous pulley and the driven synchronous pulley.

[0038] Driven by the motor 13, the lead screw 7 can rotate through the transmission of the synchronous belt assembly 14, thereby allowing the moving frame 8 to move within the housing.

[0039] like Figure 4 and Figure 5As shown, in this embodiment, the agglomeration and slitting lifting assembly includes a protective shell 5 and a hydraulic rod 22. The hydraulic rod 22 is fixedly installed above the transfer frame 8 and near the middle. The protective shell 5 is fitted over the hydraulic rod 22, and its bottom is connected to the upper end face of the transfer frame 8. The protective shell 5 is a cover-shaped shell, fitted over the hydraulic rod 22, and its bottom is fixedly connected to the upper end face of the transfer frame 8. It is used to protect the hydraulic rod 22 from feed dust contamination and external collisions. A position sensor 21 is provided on one side of the hydraulic rod 22. This position sensor 21 is a non-contact magnetostrictive displacement sensor or a Hall effect displacement sensor, used to detect the extension position of the extension end of the hydraulic rod 22 to the controller 11 in real time. The hydraulic rod 22 has a movable seat 25 fixedly installed at its telescopic end. A locking pin 27 is fixedly inserted inside the movable seat 25. Both ends of the locking pin 27 are rotatably connected to the cutting gates 19 on both sides through connecting rods 24. A slide rail is provided in the middle of the bottom of the extension air duct 16. A slide seat 31 is slidably mounted below the slide rail. The slide seat 31 can slide freely along the length of the slide rail. A connecting seat 28 is provided at the lower end of the slide seat 31. Vertical cutting slices 20 are provided at equal intervals along the horizontal direction at the bottom of the connecting seat 28. The vertical cutting slices 20 are thin sheet-like structures with a cutting edge at the lower end to assist in cutting agglomerated feed. The connecting seat 28 is rotatably engaged with the cutting gates 19 on both sides through U-shaped rotating rods 32.

[0040] Furthermore, when the telescopic end of the hydraulic rod 22 extends upward, the movable seat 25 moves upward, driving the two cutting gates 19 upward via the locking pin 27 and connecting rod 24. The connecting seat 28 slides along the slide rail via the slide block 31 to maintain balance. When the telescopic end of the hydraulic rod 22 retracts downward, the movable seat 25 moves downward, pushing the two cutting gates 19 downward to cut into the feed layer. The vertical cutting slices 20 are simultaneously inserted downward into the feed to assist in cutting.

[0041] It should be noted that the cutting frequency is detected in real time by the position sensor 21, which detects the extension and retraction stroke of the hydraulic rod 22 and feeds it back to the controller 11. The controller 11 controls the reciprocating extension and retraction of the hydraulic rod 22 according to the preset frequency and stroke parameters, so that the cutting gate 19 repeatedly cuts and lifts the agglomerated feed at the set frequency.

[0042] When the shifter 8 begins to move laterally, the hydraulic rod 22 starts to move, causing the two sets of switching gates 19 to operate.

[0043] like Figures 5-7 As shown, in this embodiment, the heat-conducting layering component includes several guide vanes 30. The several guide vanes 30 are evenly distributed along the arc-shaped trajectory of the outer surface of the slitting gate 19. Several guide oblique plates 29 are evenly arranged on one side of the several guide vanes 30. The guide oblique plates 29 are thin sheet-like structures that are inclined. The several guide oblique plates 29 extend from the root of the guide vanes 30 to the outer edge of the slitting gate 19.

[0044] Furthermore, both the guide vane 30 and the guide slant 29 are fixedly mounted on the outer surface of the slitting gate 19 and are distributed in multiple layers along the vertical direction. When the hot air ejected from the flat nozzle 26 reaches the surface of the slitting gate 19, it is first received by the guide vane 30 and guided along the surface. Then, the guide slant 29 further splits the hot air into multiple laminar flows, which are directed to feed layers at different depths and positions.

[0045] The guide vanes 30 are evenly distributed along an arc-shaped trajectory, ensuring that the hot air is guided step-by-step as it flows over the surface of the slitting gate 19. This prevents severe turbulence caused by sudden changes in airflow speed, ensuring that the hot air enters the feed layer at an appropriate speed and angle. The inclined guide vanes 29 extend obliquely from the base of the guide vanes 30 towards the outer edge of the slitting gate 19, creating a fan-shaped airflow that expands to both sides as the hot air leaves the surface of the slitting gate 19, thus increasing the coverage area of ​​the hot air in the feed layer. Simultaneously, during the lateral and vertical movements of the slitting gate 19, the guide vanes 30 and inclined guide vanes 29 move synchronously with the gate, generating additional disturbance and tumbling effects on the feed layer, further promoting full contact between the hot air and the feed particles.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, a temperature sensor 10 is installed on one side of the feed processing box 1. The temperature sensor 10 is a thermocouple or resistance temperature sensor, and its temperature probe extends into the feed processing box 1 to detect the air temperature inside the box in real time and transmit the temperature to the controller 11. The controller 11 is fixedly installed on one side of the feed processing box 1 near the temperature sensor 10. The controller 11 is a programmable logic controller (PLC) or a microcontroller control system. Its signal input terminal is electrically connected to the signal output terminal of the temperature sensor 10 through a shielded cable to receive the temperature signal fed back by the temperature sensor 10. The signal output terminal of the controller 11 is electrically connected to the control terminal of the drying fan 3, the control terminal of the motor 13, and the solenoid valve control terminal of the hydraulic rod 22, respectively, to control the start / stop, running speed, and operating frequency of each component according to the preset control logic. A feed pipe 18 is installed at the bottom of the feed processing box 1. A feed valve 6 is provided in the middle section of the feed pipe 18. The feed valve 6 is a slide gate valve or a butterfly valve, and its valve plate extends into the feed pipe 18 to open or close the channel of the feed pipe 18. When the feeding valve 6 is opened, the dried feed is discharged through the feeding pipe 18; when the feeding valve 6 is closed, the feed remains in the feed processing box 1 to continue drying.

[0047] It should be noted that the temperature sensor 10 is fixedly installed in the middle or upper part of one side wall of the feed processing tank 1. Its temperature probe extends into the tank but avoids the feed accumulation area to measure the temperature of the hot air inside the tank, rather than the internal temperature of the feed. The controller 11 is fixedly installed on the outer side wall of the feed processing tank 1 near the temperature sensor 10 to shorten the signal transmission distance and reduce signal interference. The feed pipe 18 is located at the center of the bottom of the feed processing tank 1 or off to one end, and the feed valve 6 is located in the middle section of the feed pipe 18.

[0048] The control logic of controller 11 is as follows: During equipment operation, controller 11 reads the temperature value fed back by temperature sensor 10 in real time. When the actual temperature is lower than the set value, controller 11 increases the heating power of drying fan 3 or reduces the fan speed to prolong the residence time of hot air in the heating section; when the actual temperature is higher than the set value, controller 11 reduces the heating power or increases the fan speed to prevent the feed from scorching due to excessive temperature.

[0049] Simultaneously, the controller 11 outputs control signals according to a preset timing program, controlling the motor 13 to rotate forward and backward to drive the transfer frame 8 to move back and forth horizontally, and controlling the solenoid valve of the hydraulic rod 22 to open and close to drive the cutting gate 19 to rise and fall at a set frequency. When the drying time reaches the preset duration or the temperature sensor 10 detects that the temperature change rate is lower than the set threshold, the operator is allowed to open the discharge valve 6 to discharge the material. The above control connections are common existing technologies and will not be described in detail.

[0050] Working principle: Open the airtight door 9 and put the feed to be dehumidified into the feed processing box 1. Then, activate the hydraulic opening and closing rods 12 on both sides. The hydraulic opening and closing rods 12 retract and drive the airtight door 9 to flip upward, so that the airtight door 9 and the feed processing box 1 are sealed together, ensuring that the internal hot air will not leak out, and at the same time preventing the external humid air from entering and interfering with the drying effect.

[0051] When the drying fan 3 is started, outside air enters the rectangular air duct 4 through the air inlet duct 2 and is heated to form hot air. The hot air continues to enter the extension air duct 16 and is sprayed out towards the feed layer from multiple sets of flat-nozzle air outlets 26 on both sides of the extension air duct 16. The protective filter shell 17 is fitted onto the outside of the flat-nozzle air outlets 26 to prevent feed particles from clogging the air outlets or entering the air duct, ensuring smooth airflow. After the hot air is sprayed out from the flat-nozzle air outlets 26, a uniform hot air field is formed inside the feed processing box 1.

[0052] The motor 13 is started, and the motor 13 drives the lead screw 7 to rotate through the synchronous belt assembly 14. Since the bottom of the shift frame 8 is threadedly engaged with the lead screw 7 and slidably engaged with the slide rod 15 through the connecting sleeve 23, the shift frame 8 reciprocates laterally along the direction of the lead screw 7 and the slide rod 15 when the lead screw 7 rotates. Specifically, the shift frame 8 drives the agglomeration and slitting lifting assembly and the two slitting gates 19 above it to move laterally synchronously. While the shift frame 8 moves laterally, the hydraulic rod 22 extends and retracts at a predetermined frequency. The extension end of the hydraulic rod 22 drives the movable seat 25 to move up and down reciprocally. The movable seat 25 transmits the up and down movement to the two slitting gates 19 through the locking pin 27 and the connecting rods 24 on both sides. At the same time, the two slitting gates 19 are connected to the connecting seat 28 through the U-shaped rotating rod 32. The connecting seat 28 slides along the slide rail at the bottom of the extension duct 16 through the slide seat 31, so that the two slitting gates 19 can also perform lifting and shearing movements under the drive of the hydraulic rod 22 while moving laterally with the shift frame 8. The position sensor 21 detects the extension and retraction position of the hydraulic rod 22 in real time and feeds it back to the controller 11 to precisely control the staggered frequency and stroke of the sliding gate 19 to ensure that it matches the lateral movement speed.

[0053] During this process, the two cutting gates 19, in their alternating lateral and vertical movements, shear and tear the clumps of feed, continuously breaking them down. The guide vanes 30 and guide slant vanes 29 on both sides of the cutting gates 19 further divert and guide the hot air as they move, allowing it to penetrate deep into the turned feed and preventing only the surface from being heated.

[0054] It should be noted that during the downward cutting and upward lifting processes of the slitting gate 19, a relative shearing motion is formed between the two slitting gates 19. This not only improves the slitting efficiency but also allows the feed to naturally tumble towards the center of the slitting gates 19 during the slitting process, avoiding the problem of feed being pushed in one direction and causing accumulation or compaction when a single slitting gate 19 is in motion. At the same time, the rotational engagement structure between the U-shaped rotating rod 32 and the two slitting gates 19 provides the slitting gates 19 with a certain degree of swing freedom. Even if the feed layer thickness is uneven or there are hard lumps, the slitting gates 19 can adaptively deflect at a certain angle to avoid rigid jamming or overload damage.

[0055] During the drying process, temperature sensor 10 monitors the internal temperature of feed processing box 1 in real time and feeds the signal back to controller 11. Controller 11 adjusts the power of drying fan 3 or heating temperature according to the set value to prevent the feed from scorching or losing nutrients due to excessive temperature. After drying is completed, discharge valve 6 is opened, and the dried feed is discharged and collected from discharge pipe 18.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
