Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, and specifically relates to a feed pelleting device for feed production. Background Technology

[0002] Feed pelleting equipment is a device that processes powdered or small granular feed ingredients (such as corn flour, soybean meal, wheat bran, etc.) into feed pellets of uniform size, shape, and density through compression, heating, and molding. Its main function is to improve the physical stability and palatability of feed, reduce raw material stratification, and facilitate storage, transportation, and animal consumption. The equipment typically includes a feeding system, a conditioning system, a pressure roller and die extrusion system, a cutting device, and a cooling and discharging system. During operation, the powdered material enters through the inlet, is heated and humidified in the conditioning cylinder, and then enters the pelleting chamber. The pressure rollers press the material into the die holes to form pellets, which are then cut and discharged by a cutter. It is suitable for preparing various feeds for pigs, cattle, chickens, fish, and other animals.

[0003] In the finished product output stage of feed pelleting equipment, the temperature of freshly extruded pellets is typically as high as 70-90℃, and they contain a certain proportion of free moisture. If they are not cooled and dehumidified in time, they will lead to feed clumping, oxidation, mold growth, or nutrient volatilization. Existing cooling devices mostly adopt a fixed fan downward blowing structure, with a simple cooling duct layout, high pellet density, and many ventilation dead zones, making it difficult to achieve a balanced release of temperature difference between the inner and outer layers of the pellets. This results in low cooling efficiency and unstable moisture content. At the same time, the accumulated moisture at the bottom cannot be discharged in time, and some structures even lack dedicated exhaust ports, which easily causes moisture to condense and moisturize the surface of the pellets, affecting the overall feed quality. Summary of the Invention

[0004] To address the above problems, the purpose of this utility model is to provide a feed pelleting device for feed production. This device solves the problem that, in the finished product output stage, the temperature of freshly extruded pellets is typically as high as 70-90℃, and they contain a certain proportion of free moisture. If not cooled and dehumidified in time, this will lead to feed clumping, oxidation, mold growth, or nutrient volatilization. Existing cooling devices mostly adopt a fixed fan-driven downdraft structure, with a simple cooling duct layout, high pellet density, and many ventilation dead zones. This makes it difficult to achieve a balanced temperature release between the inner and outer layers of the pellets, resulting in low cooling efficiency and unstable moisture content. Simultaneously, accumulated moisture at the bottom cannot be discharged in time, and some structures even lack dedicated exhaust ports, easily causing moisture to condense and humidify the pellet surface, affecting the overall feed quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feed pelleting device for feed production, wherein a blower is provided on one side of the feed cylinder, the feed cylinder is inserted into the upper inner side of the blower, a cylinder cover is fixedly provided on the upper side of the blower, an exhaust pipe is connected to the upper side of the cylinder cover, a motor is fixedly provided at the center of the lower side of the blower, a shaft is fixedly connected to the upper output end of the motor, a guide mesh is fixedly connected to the lower inner side of the blower and the upper side of the motor, a discharge port is opened on the lower side of the blower away from the feed cylinder, and the guide mesh is inclined downward toward the discharge port. The lower edge of the material screen plate is connected to the lower side of the discharge port. The shaft passes through the material guide screen plate and is fixedly arranged with staggered and equidistant mesh hoppers and flat mesh discs on the upper side. The mesh hoppers are arranged opposite each other on the upper side of the flat mesh discs. The middle of the mesh hoppers has a discharge port. The outer side of the mesh hoppers is close to the inner wall of the air duct. There is a gap between the outer side of the flat mesh discs and the air duct. The bottom inner side of the material cylinder is fixedly arranged with an air outlet ring on the outer side of the second motor. The output end of the air outlet ring faces upward. A high-speed fan is arranged on one side of the outer side of the air duct. The output end of the high-speed fan passes through the inner side of the air duct and is fixedly connected to the air outlet ring.

[0006] The beneficial effects of this invention are as follows: the feed pellets can fall layer by layer through the rotating and rolling mesh hopper and flat mesh disc, which greatly increases the total distance of the fall, resulting in a longer drying time and more thorough drying. It can also roll and shape the freshly formed feed pellets, making them less prone to loosening. At the same time, the airflow blows from bottom to top, continuously drying the surface of the feed pellets. The moisture it carries away will rise and detach from the feed, ensuring that the dried feed pellets below are not affected by moisture and guaranteeing the drying effect.

[0007] To cover the top of the hopper;

[0008] As a further improvement to the above technical solution: the upper side of the hopper is provided with a hopper cover, which is made of transparent glass.

[0009] The beneficial effects of this improvement are: it can cover the upper side of the hopper without affecting the observation of the feed ingredients, and prevent foreign objects from falling into the feed ingredients.

[0010] In order to observe the pushing and squeezing of feed ingredients inside the feed cylinder;

[0011] As a further improvement to the above technical solution: an observation window is provided on the side of the barrel near the cutter head.

[0012] The beneficial effects of this improvement are: the addition of an observation window allows for observation of the pushing and squeezing of feed ingredients inside the feed cylinder.

[0013] For use in collecting condensate;

[0014] As a further improvement to the above technical solution: an exhaust fan is connected to the output end of the exhaust pipe, a water collection tank is connected to the lower output end of the exhaust fan, an air outlet is opened on the upper side of the water collection tank away from the exhaust fan, a drain outlet is connected to the lower side of the water collection tank away from the air duct, and a plug is provided at the output end of the drain outlet.

[0015] The beneficial effects of this improvement are as follows: the feed pellets contain a large amount of water vapor, which will condense rapidly when it is separated from the feed and discharged through the exhaust pipe. An exhaust fan is set up to assist in the extraction of air, and a water collection tank is set up to collect the condensate.

[0016] To increase the condensation effect of water vapor;

[0017] As a further improvement to the above technical solution: fine-perforated condensation plates are fixedly installed at equal intervals on the inner side of the water collection tank.

[0018] The beneficial effect of this improvement is that the fine-pore condenser plate increases the condensation effect of water vapor.

[0019] For use in intercepting cooling return water;

[0020] As a further improvement to the above technical solution: a water receiving ring is fixedly installed on the inner top of the air duct near the second cover, and a return pipe is connected to the side of the air duct corresponding to the water receiving ring, and the return pipe and the exhaust pipe are fixedly connected.

[0021] The beneficial effects of this improvement are as follows: when the water vapor reaches the inner wall of the second cylinder cover, the water vapor will directly condense on the inner side wall of the second cylinder cover. A water receiving ring is provided to intercept the cooling return water, which can then be discharged through the return pipe into the exhaust pipe.

[0022] To prevent condensation from dripping directly downwards;

[0023] As a further improvement to the above technical solution: the second cylindrical cover is an inverted bucket-shaped cover.

[0024] The beneficial effect of this improvement is that it ensures that condensate flows into the water ring, preventing condensate from dripping directly downwards.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] like Figure 1 — Figure 5As shown: A feed pelleting device for feed production, wherein a duct 10 is provided on one side of the feed cylinder 1, the feed cylinder 1 is inserted into the upper inner side of the duct 10, a cylinder cover 2 11 is fixedly provided on the upper side of the duct 10, and an exhaust pipe 12 is connected to the upper side of the cylinder cover 2 11, a motor 2 13 is fixedly provided at the center of the lower side of the duct 10, and a shaft 14 is fixedly connected to the upper output end of the motor 2 13, a guide mesh plate 15 is fixedly connected to the lower inner side of the duct 10 and the upper side of the motor 2 13, and a discharge port 16 is opened on the lower side of the duct 10 away from the feed cylinder 1, the guide mesh plate 15 is inclined downward toward the discharge port 16, and the lower edge of the guide mesh plate 15 is connected to the lower side of the discharge port 16, and the shaft 14 is fixedly provided. A mesh concave hopper 17 and a flat mesh disk 18 are fixedly and alternately at equal intervals on the upper side of the feed guide plate 15. The mesh concave hopper 17 is positioned opposite to the flat mesh disk 18 on the upper side. A feed outlet is opened in the middle of the mesh concave hopper 17. The outer side of the mesh concave hopper 17 is close to the inner wall of the air duct 10. There is a gap between the outer side of the flat mesh disk 18 and the air duct 10. An air outlet ring 19 is fixedly installed on the inner bottom of the feed cylinder 1, outside the motor 13. The output end of the air outlet ring 19 faces upward. A high-speed fan 20 is installed on one side of the outer side of the air duct 10. The output end of the high-speed fan 20 penetrates into the inner side of the air duct 10 and is fixedly connected to the air outlet ring 19. The feed pellets can pass through the rotating rollers of the mesh concave hopper 17 and the flat mesh disk 18 layer by layer. The airflow increases the total distance the feed pellets travel, resulting in a longer drying time and more thorough drying. It also rolls and shapes the newly formed feed pellets, preventing them from crumbling. Simultaneously, the airflow blows from bottom to top, continuously drying the surface of the feed pellets. The moisture carried away rises away from the feed, ensuring the dried pellets below are not affected by moisture, thus guaranteeing the drying effect. A hopper cover 6, made of transparent glass, is installed on the upper side of the hopper 5 to cover the upper side of the hopper 5, allowing observation of the feed materials. An observation window 9 is provided on the side of the feed cylinder 1 near the cutter head 8 to observe the pushing and squeezing of the feed materials inside the cylinder 1. The output end of the exhaust pipe 12 is connected to a vacuum pump. The fan 21 has a water collection tank 22 connected to its lower output end. An air outlet 23 is located on the upper side of the water collection tank 22, away from the fan 21. A drain outlet 24 is connected to the lower side of the water collection tank 22, away from the air duct 10. A plug is installed at the output end of the drain outlet 24. The feed pellets contain a large amount of water vapor, which condenses rapidly when it is released from the feed and discharged through the exhaust pipe 12. The fan 21 is used to assist in air extraction, and the water collection tank 22 is used to collect the condensate. Fine-perforated condensation plates 25 are fixedly installed at equal intervals on the inner center of the water collection tank 22 to increase the condensation effect of the water vapor. A water receiving ring 101 is fixedly installed on the inner top of the air duct 10, near the duct cover 11.A return pipe 121 is connected to the side of the air duct 10, corresponding to the water receiving ring 101. The return pipe 121 is fixedly connected to the exhaust pipe 12. When water vapor reaches the inner wall of the second cover 11, it condenses directly on the inner side wall of the second cover 11. The water receiving ring 101 is provided to intercept the cooling return water, which then flows back to the exhaust pipe 12 through the return pipe 121 and is discharged. The second cover 11 is an inverted funnel-shaped cover to ensure that the condensate flows into the water receiving ring 101 and prevents the condensate from dripping directly downwards.

[0034] Working principle and usage process of this utility model:

[0035] In use, the cylinder cover 2 is fixedly installed at the end of the material cylinder 1 away from the air duct 10. A motor 3 is fixedly installed on the side of the cylinder cover 2 away from the material cylinder 1. The output end of the motor 3 passes through the inside of the cylinder cover 2 and is fixedly connected to the spiral auger 7. A support frame 4 is fixedly installed on the lower side of the material cylinder 1. A hopper 5 is fixedly connected to the upper side of the material cylinder 1 near the cylinder cover 2. Particle outlet holes are evenly distributed on the side of the material cylinder 1 away from the cylinder cover 2. A cutter disc 8 is rotatably installed at the center of the side of the material cylinder 1 away from the cylinder cover 2. The cutter disc 8 passes through the inside of the material cylinder 1 and connects with the spiral auger 7. The screw conveyor 7 is coaxially fixedly connected. This structure is the basic component of existing feed pellet mills. During use, the prepared feed material is placed into the hopper 5, and motor 3 is started. The output of motor 3 drives the screw conveyor 7 to rotate. The raw material is pushed towards the pellet outlet through the screw conveyor 7, and extruded through the outlet to form pellets. Simultaneously, the cutter disc 8 rotates and cuts the extruded material. The feed pellets fall after being cut, landing on the uppermost mesh concave hopper 17. At this time, the output of motor 13 drives the shaft 14 to rotate, and the shaft 14 drives the mesh concave hopper 17 and... The flat mesh disk 18 rotates, controlling the rotation speed of the motor 13, causing the feed pellets to roll on the mesh hopper 17 towards the central feeding port. After falling from the center onto the flat mesh disk 18, the feed pellets are subjected to centrifugal force and roll towards the edge of the flat mesh disk 18, then fall onto the upper side of the lower mesh hopper 17. This cycle repeats until the pellets finally fall onto the guide mesh plate 15 and are discharged from the discharge port 16. During the repeated feeding of feed pellets, the high-speed fan 20 starts, blowing air upwards through the air outlet ring 19. The airflow rises layer by layer through the flat mesh disk. The feed pellets, passing through the mesh concave hopper 17 and the flat mesh hopper 18, finally exit through the exhaust pipe 12. Following this process, the feed pellets roll and fall sequentially through the mesh concave hopper 17 and the flat mesh hopper 18, significantly increasing the total distance traveled and resulting in a longer drying time and more thorough drying. This rolling and shaping process also helps to prevent the feed pellets from crumbling. Simultaneously, the airflow blows from bottom to top, continuously drying the surface of the feed pellets. The moisture carried away rises away from the feed, ensuring that the dried pellets below are not affected by moisture, thus guaranteeing the drying effect. Furthermore, a hopper cover 6 is provided to cover the upper side of the hopper 5, allowing observation of the feed materials and preventing foreign objects from falling into them. An observation window 9 is also provided to observe the pushing and squeezing of the feed materials inside the feed cylinder 1. Additionally, the feed pellets contain a large amount of moisture, which condenses rapidly as it exits the feed and exits through the exhaust pipe 12. An exhaust fan 21 is provided to assist in extraction, and a water collection tank 22 is provided to collect the condensate. In addition, a fine-pore condenser plate 25 is installed to increase the condensation effect of water vapor.In addition, when the water vapor reaches the inner wall of the second cover 11, the water vapor will condense directly on the inner side wall of the second cover 11. A water receiving ring 101 is provided to intercept the cooling return water, which can then be discharged through the return pipe 121 into the exhaust pipe 12. Furthermore, the second cover 11 is an inverted bucket-shaped cover to ensure that the condensate flows into the water receiving ring 101 and prevents the condensate from dripping directly downwards.
