Description

Technical Field

[0001] This utility model relates to the field of feed sterilization technology, specifically to a high-temperature sterilization device for raw materials used in the preparation of cattle and sheep feed. Background Technology

[0002] Feed ingredients (such as grains, straw, silage, etc.) are easily contaminated by molds (such as Aspergillus flavus) and bacteria (such as Salmonella), leading to mold growth or toxin residues, which threaten the health of cattle and sheep. When preparing cattle and sheep feed, processing feed ingredients into pellets allows for control over the density, shape, and particle size of pelleted feed. High-temperature steam or dry heat penetration is more uniform, avoiding sterilization dead zones (such as internal mold spore residues) caused by clumping in traditional powdered feed. Furthermore, the surface of pelleted feed is smooth, reducing hygroscopicity (pellet moisture ≤12%, powder ≥15%), making it less prone to bacterial or mold growth during storage. Therefore, high-temperature sterilization (such as high-temperature ultraviolet sterilization) of pelleted feed to improve the safety of cattle and sheep feeding is a necessary measure. For example, Chinese patent application number CN201410238316.4 discloses a Caragana korshinskii pelleted feed and its preparation method, further verifying the necessity of high-temperature sterilization of pelleted feed.

[0003] Current high-temperature sterilization devices, when sterilizing cattle and sheep feed pellets, use agitation to ensure sufficient contact between the feed and the high temperature. However, when the feed is gathered in the same container and agitated, the agitation intensity is high and a large amount of feed accumulates, making it difficult for the feed at the bottom to be exposed, thus limiting the sterilization effect. In view of this, we propose a high-temperature sterilization device for raw materials used in cattle and sheep feed preparation. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings and provide a high-temperature sterilization device for raw materials used in the preparation of cattle and sheep feed.

[0005] To achieve the above objectives, this utility model provides a high-temperature sterilization device for raw materials used in the preparation of cattle and sheep feed, including a high-temperature furnace. A feeding hopper is connected to the top of the high-temperature furnace near its edge, and a discharge port is connected to the side wall of the high-temperature furnace near its bottom. The high-temperature furnace is equipped with multiple rotating perturbed bearing plates. The ends of the multiple perturbed bearing plates are staggered with notches between them and the high-temperature furnace, and the upper notch is located directly above the surface of the lower perturbed bearing plate.

[0006] Multiple disturbance bearing plates are synchronously oscillating inside the high-temperature furnace via a drive component, alternately receiving the tilted and sliding cattle and sheep feed.

[0007] As a further improvement to this technical solution, the inner layer of the high-temperature furnace is embedded with an electric heating grid and a temperature sensor, and both the electric heating grid and the temperature sensor are electrically connected to a controller. The temperature sensor senses the temperature inside the high-temperature furnace, and when the temperature is lower than the critical value for high-temperature sterilization, the controller is driven to control the electric heating grid to adjust the temperature to above the critical value.

[0008] As a further improvement to this technical solution, the disturbance support plate is equipped with an ultraviolet disinfection lamp, which is used to disinfect the feed through the disturbance support plate.

[0009] As a further improvement to this technical solution, the inner wall of the high-temperature furnace is an arc-shaped structure, and one end of the disturbance bearing plate is attached to the arc-shaped structure of the high-temperature furnace.

[0010] As a further improvement to this technical solution, a circulating conveying cylinder is connected to the end of the discharge port, and a spiral conveying rod is rotatably installed inside the circulating conveying cylinder;

[0011] The top of the spiral conveyor is fixedly connected to the output shaft of the conveyor motor, and the housing of the conveyor motor is fixed to the top of the circulating conveyor cylinder.

[0012] As a further improvement to this technical solution, a guide frame is connected to the outer wall of the circulating conveying cylinder near the top, and the end of the guide frame is located directly above the feed hopper.

[0013] As a further improvement to this technical solution, the bottom of the discharge port cavity is inclined toward the circulating conveying cylinder, and the bottom of the guide frame cavity is inclined toward the feed hopper.

[0014] As a further improvement to this technical solution, a gear set is provided between the rotating shafts of the multi-layer disturbance bearing plate, and the end of the gear on one of the gear sets is connected to the output shaft of the disturbance motor. The housing of the disturbance motor is fixed to the outer wall of the high-temperature furnace.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this high-temperature sterilization device for raw materials used in cattle and sheep feed preparation, feed is fed into the high-temperature furnace from the feed hopper. The feed falls directly onto the top of the disturbance support plate. As the disturbance support plate tilts towards the notch, the feed falls onto the lower disturbance support plate, thus agitating the feed during transmission. This prevents the feed from accumulating in one space, which would otherwise have a limited agitation effect. Furthermore, as the disturbance support plate rotates, the feed that has not yet tilted and fallen is agitated along the surface of the disturbance support plate, which helps to flip the feed covered at the bottom to the top, improving the high-temperature sterilization effect.

[0017] Furthermore, the disturbance bearing plate is in a dynamic swing state, which can also disturb the feed blocked at the gap, reducing the possibility of blockage. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 As shown, this embodiment provides a high-temperature sterilization device for raw materials used in cattle and sheep feed preparation, including a high-temperature furnace 100. A feeding hopper 110 is connected to the top of the high-temperature furnace 100 near its edge, and a discharge port 120 is connected to the side wall of the high-temperature furnace 100 near its bottom. This allows the pellets made from cattle and sheep raw materials to be fed into the high-temperature furnace 100 from the feeding hopper 110, so that the high temperature generated inside the high-temperature furnace 100 can sterilize the cattle and sheep raw materials. After sterilization, the pellets can be discharged from the discharge port 120, ensuring the rationality of the structure. The high-temperature furnace 100 is equipped with a rotating multi-layered disturbance bearing plate 200. The ends of the multiple disturbance bearing plates 200 are staggered with notches between them and the high-temperature furnace 100, and the upper notch is located directly above the surface of the lower disturbance bearing plate 200.

[0027] Multiple disturbance bearing plates 200 swing synchronously inside the high-temperature furnace 100 via a drive component, alternately receiving the tilted and sliding cattle and sheep feed.

[0028] The improvement in this embodiment lies in the fact that, because the bottom of the feed is covered during high-temperature sterilization of cattle and sheep feed raw materials or pelleted feed, the high-temperature sterilization effect is limited. Therefore, as... Figure 1-3 As shown, feed is fed into the high-temperature furnace 100 from the feed hopper 110. The feed falls directly onto the top of the disturbance support plate 200. As the disturbance support plate 200 tilts towards the notch, the feed falls onto the lower disturbance support plate 200, thus agitating the feed during transmission and preventing it from accumulating in one space with limited agitation effect. Furthermore, as the disturbance support plate 200 rotates, the feed that has not yet tilted and fallen is agitated along the surface of the disturbance support plate 200, which helps to flip the feed covered at the bottom to the top, improving the high-temperature sterilization effect.

[0029] Furthermore, the disturbance bearing plate 200 is in a dynamic swing state, which can also disturb the feed blocked at the gap and reduce the possibility of blockage;

[0030] Specifically, such as Figure 3 As shown, when the disturbance bearing plate 200 swings back and forth from a1→b1→c1→b1→a1, the feed is turned over and disturbed at the top. When it is in state a1, it is tilted towards the notch, and the feed can slide down the slope and fall to the disturbance bearing plate 200 below, which continues to swing from a2→b2→c2→b2→a2. This process is repeated to realize the transmission of feed in different areas and the turning and disturbance at the same time, which increases the probability of the feed being exposed and helps to improve sterilization efficiency.

[0031] To achieve high-temperature sterilization of cattle and sheep feed within the high-temperature furnace 100, an electric heating grid and temperature sensors need to be embedded in the inner layer of the furnace 100. Both the electric heating grid and the temperature sensors are electrically connected to a controller. The temperature sensors detect the temperature inside the high-temperature furnace 100. When the temperature is below the critical value for high-temperature sterilization, the controller drives the electric heating grid to adjust the temperature above the critical value. Therefore, the electric heating grid is made of high-temperature resistant resistive material (such as nickel-chromium alloy) and is distributed in the inner layer of the high-temperature furnace 100. After being energized, it generates Joule heat to uniformly heat the furnace cavity. The temperature sensors are thermocouples or thermistors, embedded in key locations inside the furnace (such as the center or multiple points), to monitor the temperature in real time and convert it into an electrical signal. The controller is usually a PLC or microcontroller (such as Arduino), which has signal processing, logic operation, and output control functions, and is connected to the electric heating grid and sensors through circuitry.

[0032] The user presets a high-temperature sterilization threshold (e.g., 121℃). The controller starts a self-test program, and the sensor continuously collects the temperature inside the furnace, converting the analog signal (e.g., the millivolt signal from a thermocouple) into a digital signal input to the controller. The controller compares the current temperature with the set threshold to determine whether heating is required. The controller outputs current to the heating grid for full-power heating. If the threshold is reached or exceeded, the power of the heating grid is cut off or reduced (e.g., through PWM voltage regulation), and the system enters the heat preservation mode. This forms a closed-loop feedback, continuously monitoring, comparing, and adjusting to ensure that the temperature remains stable within the set range.

[0033] Furthermore, the disturbance support plate 200 is equipped with an ultraviolet disinfection lamp, which is used to disinfect feed through the disturbance support plate 200. The ultraviolet disinfection lamp uses ultraviolet light of a specific wavelength (mainly UVC) with a wavelength of 200-280 nanometers to destroy the DNA / RNA structure of microorganisms, causing them to lose their ability to replicate, thereby achieving the effect of sterilization and disinfection.

[0034] Next, the inner wall of the high-temperature furnace 100 has an arc-shaped structure, and one end of the disturbance bearing plate 200 is attached to the arc-shaped structure of the high-temperature furnace 100. The arc-shaped structure better conforms to the natural flow path of the fluid or particles, reducing turbulence and flow separation, reducing pressure loss, thereby improving conveying efficiency and reducing energy consumption (especially at bends). At the same time, the design without sharp corners avoids material accumulation and reduces the frequency of downtime for cleaning. In addition, when the disturbance bearing plate 200 rotates, one end is attached to the inner wall of the high-temperature furnace 100, which is conducive to scraping the attached feed and avoiding long-term adhesion that is not conducive to cleaning.

[0035] Considering that the effect of a single high-temperature sterilization process is limited, a circulating conveyor cylinder 130 is connected to the end of the discharge port 120, and a spiral conveyor rod 131 is rotatably installed inside the circulating conveyor cylinder 130.

[0036] The top of the spiral conveyor 131 is fixedly connected to the output shaft of the conveyor motor 132, and the housing of the conveyor motor 132 is fixed to the top of the circulating conveyor cylinder 130. When the conveyor motor 132 is powered on, it will work and the feed discharged from the discharge port 120, that is, the feed falling from the bottom disturbance bearing plate 200, can enter the interior of the circulating conveyor cylinder 130 through the discharge port 120, causing the spiral conveyor 131 to rotate and transport the feed at the bottom to the top. During this process, the feed is further disturbed. If it is sterilized at high temperature, it can also be disturbed and cooled to facilitate the subsequent collection of feed.

[0037] Specifically, a guide frame 140 is connected to the outer wall of the circulating conveyor cylinder 130 near the top. The end of the guide frame 140 is located directly above the feed hopper 110. When the high-temperature sterilization effect is insufficient, the feed at the top of the circulating conveyor cylinder 130 is transferred through the guide frame 140, causing the feed to fall into the feed hopper 110 and re-enter the high-temperature furnace 100 for high-temperature sterilization, thus achieving circulating sterilization and ensuring sterilization quality. Furthermore, if re-sterilization is not required, the feed hopper 110 can be covered, and the sterilized feed can be received from the end of the guide frame 140. This is something that those skilled in the art can easily conceive of, and will not be elaborated here.

[0038] Furthermore, based on the above, the bottom of the inner cavity of the discharge port 120 is inclined toward the circulating conveyor cylinder 130, and the bottom of the inner cavity of the guide frame 140 is inclined toward the feed hopper 110, so as to ensure that the sterilized feed can enter the circulating conveyor cylinder 130 more fully and quickly, and the circulating feed can enter the feed hopper 110 more fully and quickly for circulation.

[0039] Furthermore, a power source is required when the multi-layer disturbance bearing plate 200 rotates; therefore, such as Figure 4 As shown, a gear set 210 is provided between the rotating shafts of the multi-layer disturbance bearing plate 200. The end of a gear on one of the gear sets 210 is connected to the output shaft of a disturbance motor 220. The housing of the disturbance motor 220 is fixed to the outer wall of the high-temperature furnace 100. The gear set 210 consists of multiple meshing gears. When one gear rotates, it drives multiple gears to rotate simultaneously. The number of gears can be customized according to the usage environment. Figure 4 This is just an illustration and does not limit the quantity or size. Therefore, the output shaft of the disturbance motor 220 drives multiple gear sets 210 to reciprocate in an oscillating manner, so as to realize the simultaneous rotation of the multi-layer disturbance bearing plate 200, thereby disturbing and sterilizing the feed.

[0040] As for the output shaft of the disturbance motor 220, the motor direction (forward rotation → reverse rotation → forward rotation...) is periodically switched by the circuit or controller. Specifically, it requires an electronic controller (such as a microcontroller or PLC) to adjust the swing parameters (frequency and amplitude are programmable) to realize the setting command, so that its output shaft rotates left and right, thereby driving the disturbance bearing plate 200 to rotate back and forth. This working principle is existing technology, and those skilled in the art can customize the settings according to the swing amplitude.

[0041] In practical use, the high-temperature sterilization device for cattle and sheep feed preparation utilizes a perturbation motor 220 whose output shaft drives multiple gear sets 210 to reciprocate in an oscillating manner. This causes multiple perturbation support plates 200 to rotate simultaneously. Cattle and sheep feed pellets are then fed from the feed hopper 110 into the high-temperature furnace 100, where the high temperature generated inside the furnace sterilizes the feed. As the feed falls onto the top of the perturbation support plates 200, these plates tilt towards a notch, causing the feed to fall onto the lower perturbation support plates 200. The feed falling from the bottom perturbation support plate 200 enters the circulating conveyor cylinder 130 through the discharge port 120. The rotating screw conveyor 131 transports the feed from the bottom to the top, where it is transferred via the guide frame 140 to the top of the circulating conveyor cylinder 130, falling back into the feed hopper 110 and re-entering the high-temperature furnace 100 for high-temperature sterilization, thus achieving cyclic sterilization.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
