Description

Technical Field

[0001] The utility model belongs to the technical field of feed ripening, and particularly relates to a feed ripening device. Background Art

[0002] In the feed ripening and conditioning process, as a core part of the feed processing flow, its importance is self-evident. In the conditioner, the ingenious use of high-pressure steam is crucial. It not only provides the necessary heat and moisture for starch gelatinization, tight adhesion of particles, and effective killing of pathogens in the feed, but also profoundly affects the quality and production efficiency of the final pellet feed. The temperature of the steam and the residence time of the material in the conditioner, these two factors are like a double-edged sword. Under precise control, they can significantly improve the production efficiency of the feed, optimize the physical properties of the pellets, and have a positive impact on the growth performance of animals such as poultry.

[0003] However, traditional feed ripening devices often lack in the aspects of steam injection and heating uniformity. They often adopt the method of directly injecting steam into the chamber, which is difficult to ensure the full diffusion and uniform heating of steam in the feed, thus affecting the ripening effect and feed quality. In order to overcome this problem and further improve the stability of feed products, modern ripening devices innovatively adopt a double-layer design and a double-screw conveyor structure. Although it prolongs the residence time of the feed in the conditioner and provides sufficient time guarantee for the full reaction of steam and feed, it results in an increase in the volume of the device and the need to set two screws, which increases the overall cost.

[0004] Therefore, it is very necessary to invent a feed ripening device. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a feed ripening device, which includes a ripening conditioner, a modulating reverse conveying and quality-preserving device, a hopper opening, and a driving motor. The modulating reverse conveying and quality-preserving device and the hopper opening are fixedly installed outside the ripening conditioner. The modulating reverse conveying and quality-preserving device and the hopper opening are located on one side of each other. The driving motor is fixedly installed at one end of the ripening conditioner.

[0006] The aging and conditioning device includes a housing, a steam delivery shaft, spiral blades, steam diffusion holes, a return port, a steam injection pipe opening, and a bracket. The conditioning reverse delivery and quality preservation device and the hopper opening are fixedly installed on the housing. The steam delivery shaft is rotatably installed inside the housing, and one end of it rotatably passes through and is fixed to the output end of the driving motor fixedly installed outside it. The spiral blades are fixedly installed on the steam delivery shaft, and a plurality of the steam diffusion holes are evenly distributed. A plurality of the return ports are arranged on the outer surface of one end of the housing. The support is fixedly installed on the end face of one end of the return port. The steam injection pipe opening is fixedly installed on the support. One end of the steam injection pipe opening rotatably passes through the housing and is hermetically and rotatably communicated with one end of the steam delivery shaft.

[0007] The conditioning reverse delivery and quality preservation device includes a return cylinder, a blanking cover cylinder, a heating cylinder, and a heater. The return cylinder and the blanking cover cylinder are fixedly installed outside the housing and are communicated with each other. The heating cylinder and the heater are respectively fixedly installed inside and outside the return cylinder.

[0008] Preferably, the plurality of the steam diffusion holes provided on the steam delivery shaft are arranged in a spiral path, and the steam diffusion holes are located between the pitches of the spiral blades. The spiral blades do not affect the discharge of steam from the steam diffusion holes.

[0009] Preferably, the steam delivery channel provided on the steam delivery shaft is communicated with the steam injection pipe opening. The steam injection pipe opening is an L-shaped elbow pipe with its pipe opening facing upward and is connected to the steam output port of the steam generator.

[0010] Preferably, the return ports are evenly distributed in a circular array at one end of the housing. The return ports are located on one side of the steam injection pipe opening. No steam diffusion holes are provided in the area of one end of the steam delivery shaft where the return ports are located.

[0011] Preferably, the housing and the return cylinder form a chamber channel allowing the feed to be conveyed. This chamber channel is communicated with the chamber formed inside the housing through the return ports. The heater is located in the feed conveying chamber.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This utility model abandons the limitations of traditional direct steam injection and innovatively introduces a central injection and diffusion mechanism. Through the steam delivery shaft as the core medium, steam is diffused outward evenly and stably throughout the interior of the chamber. This not only ensures the wide distribution and uniformity of steam but also greatly improves the heat transfer efficiency. During the steam transportation process, its high-temperature characteristic is naturally conducted to the spiral blades through the steam delivery shaft, further strengthening the uniform distribution of heat in the feed, thus achieving a more refined and efficient cooking effect.

[0014] This utility model ingeniously adopts a single-screw structure. Through the pressure generated by the rotation and pushing of the screw, continuous and stable transportation of the feed is achieved. This simplified design not only reduces the complexity and manufacturing cost of the equipment but also significantly reduces the floor area, making the equipment layout more compact and reasonable. At the same time, after the feed enters the modulation reverse transportation and preservation device, it undergoes the reverse transportation process, fully frictions with the inner wall of the return barrel, and combined with the continuous heating effect of the heating barrel, further increases the temperature of the feed, ensuring the maximization of the cooking degree. Finally, the cooked feed is smoothly discharged through the blanking cover barrel, and the whole process is smooth without obstruction, which not only ensures the quality of the feed but also improves the production efficiency.

[0022] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0023] A feed ripening device provided by the present invention includes a ripening conditioner 1, a modulation reverse conveying and quality-preserving device 2, a hopper opening 3, and a driving motor 4. The modulation reverse conveying and quality-preserving device 2 and the hopper opening 3 are fixedly installed outside the ripening conditioner 1, and the modulation reverse conveying and quality-preserving device 2 and the hopper opening 3 are located on one side of each other. The driving motor 4 is fixedly installed at one end of the ripening conditioner 1.

[0024] Further, the ripening conditioner 1 includes a housing 11, a steam conveying shaft 12, a spiral blade 13, steam diffusion holes 14, a return port 15, a steam injection pipe opening 16, and a bracket 17. The modulation reverse conveying and quality-preserving device 2 and the hopper opening 3 are fixedly installed on the housing 11. The steam conveying shaft 12 is rotatably installed inside the housing 11 and passes through one end of the steam conveying shaft 12 and is fixed to the output end of the driving motor 4 fixedly installed outside thereof; the spiral blade 13 is fixedly installed on the steam conveying shaft 12, and a plurality of the steam diffusion holes 14 are evenly arranged; a plurality of the return ports 15 are arranged on the outer surface of one end of the housing 11, the bracket 17 is fixedly installed on the end surface of one end of the return port 15, the steam injection pipe opening 16 is fixedly installed on the bracket 17, and one end of the steam injection pipe opening 16 rotates through the housing 11 and is hermetically and rotationally communicated with one end of the steam conveying shaft 12.

[0025] Further, the modulation reverse conveying quality preservator 2 includes a folding-back cylinder 21, a blanking cover cylinder 22, a heating cylinder 23 and a heater 24. The folding-back cylinder 21 and the blanking cover cylinder 22 are fixedly installed outside the housing 11 and are interconnected with each other. The heating cylinder 23 and the heater 24 are fixedly installed inside and outside the folding-back cylinder 21 respectively.

[0026] Further, numerous steam diffusion holes 14 arranged on the steam conveying shaft 12 adopt a spiral path distribution method. These holes are cleverly located between the pitches of the spiral blades 13, ensuring that during the rotation of the spiral blades 13, steam can smoothly and evenly pass through the diffusion holes 14 and be discharged into the feed. It should be noted that the design of the spiral blades 13 does not cause any obstruction to the discharge of steam. Instead, through its rotational movement, it promotes the full mixing of steam and feed, further enhancing the ripening effect.

[0027] Further, a steam conveying channel is provided inside the steam conveying shaft 12, and this channel is closely connected to the steam injection nozzle 16, forming an efficient steam transmission system. The steam injection nozzle 16 adopts an L-shaped elbow design with its nozzle facing upward. This ingenious layout not only avoids the problem of steam condensation and backflow but also ensures that steam can be directly and stably injected into the steam conveying shaft 11. In addition, the steam injection nozzle 16 is closely connected to the steam output port of the steam generator, ensuring the continuity and stability of steam supply.

[0028] Further, a circular array of folding-back ports 15 is evenly distributed at one end of the housing 11. These folding-back ports 15 not only play the role of connecting the inner and outer chambers but also optimize the contact path between steam and feed. It should be noted that near the folding-back ports 15, no steam diffusion holes 14 are provided on the steam conveying shaft. This design avoids the direct escape of steam through the folding-back ports 15, ensuring the effective distribution and utilization of steam in the chamber.

[0029] Further, the housing 11 and the folding-back cylinder 21 together form a chamber channel for feed conveying. This channel communicates with the inner chamber of the housing 11 through the folding-back ports 15, forming a continuous and smooth feed conveying path. The heater 24 is located inside the chamber and continuously heats the feed during the feed conveying process, further enhancing the ripening degree and temperature uniformity of the feed. This design not only improves the processing efficiency of the feed but also ensures the stability of feed quality.

[0030] The working principle is as follows: First, the feed enters the interior of the housing 11 of the ripening conditioner 1 through the hopper opening 3. At this time, the drive motor 4 is started, driving the steam conveying shaft 12 and the spiral blades 13 fixed thereon to start rotating. As the spiral blades 13 rotate, the feed is gradually pushed forward and enters the area where steam and feed are mixed.

[0031] Then, the steam generated by the steam generator is injected into the steam delivery channel of the steam delivery shaft 12 through the steam injection nozzle 16. Since the steam injection nozzle 16 is designed as an L-shaped elbow with the nozzle facing upward, it effectively prevents the steam from condensing and flowing back. The steam then passes through the evenly distributed steam diffusion holes 14 on the steam delivery shaft 12 and is evenly discharged into the feed in a spiral path. The steam diffusion holes 14 are located between the pitches of the spiral blades 13, ensuring that the steam can smoothly mix with the feed during the rotation of the spiral blades, achieving uniform heating and cooking.

[0032] While the steam is mixing with the feed, the feed continues to move forward under the push of the spiral blades 13 and enters the modulation reverse delivery quality retainer 2 through the turning port 15 at one end of the outer shell 11. It should be noted that near the turning port 15, no steam diffusion holes 14 are provided on the steam delivery shaft to prevent the steam from directly escaping through the turning port, ensuring the effective distribution and utilization of the steam in the chamber.

[0033] After entering the modulation reverse delivery quality retainer 2, the feed first enters the turning cylinder 21 and undergoes preliminary heat exchange with the heating cylinder 23 inside it. Subsequently, the feed is reversely conveyed through the feeding hood cylinder 22. During this process, the feed rubs against the inner wall of the turning cylinder 21, further increasing the temperature of the feed. At the same time, the heater 24 is located in the feed delivery chamber to continuously heat the feed, ensuring the temperature stability and cooking effect of the feed during the conveying process.

[0034] Finally, the fully cooked and heated feed is smoothly discharged through the feeding hood cylinder 22, completing the entire cooking process. Through the innovative steam injection method and the design of the modulation reverse delivery quality retainer, this equipment not only improves the cooking efficiency and uniformity of the feed, but also reduces the overall floor area and manufacturing cost of the equipment, bringing significant technological progress to the feed processing industry.

[0035] Any technical solution that uses the technical solution described in this utility model, or is designed by those skilled in the art inspired by the technical solution of this utility model to achieve the above technical effects, shall fall within the protection scope of this utility model.
