Description

Technical Field

[0001] This invention relates to the technical field of feed preparation, and in particular to a method and equipment for preparing animal feed using waste squid viscera. Background Technology

[0002] Animal feed preparation requires animal-derived raw materials, commonly including animal bone meal or fish meal. Waste squid viscera are also frequently used as a raw material. For example, Chinese invention patent application CN121220638A proposes a crab feed to improve the quality of crab roe. This feed consists of the following feed ingredients by weight: 15-25 parts white fish meal, 10-15 parts fermented soybean meal, 50-60 parts squid viscera powder, 45-50 parts krill powder, 25-30 parts brewer's yeast, 200-220 parts high-gluten flour, 45-50 parts wheat bran, 10-20 parts soybean lecithin oil, 5-10 parts crab-specific vitamin premix, and 5-10 parts crab-specific mineral premix.

[0003] The aforementioned feed uses squid viscera powder. However, existing technologies lack methods and equipment for directly preparing animal feed using fresh, frozen waste squid viscera as raw materials. Squid viscera naturally contain a large amount of water, which means that first preparing squid viscera powder and then using the squid viscera powder to prepare animal feed is energy-intensive and complex. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a raw material preparation method and equipment for preparing animal feed from waste squid viscera, which directly prepares raw material pellets from fresh frozen squid viscera into animal feed, with low energy consumption, simplified process flow, and high work efficiency.

[0005] The present invention relates to a raw material preparation device for preparing animal feed using waste squid viscera, comprising: a crushing mechanism for crushing frozen fresh squid viscera into granules and feeding the squid viscera granules into a pelletizing mechanism; a pelletizing mechanism for mixing auxiliary powder with the squid viscera granules, wherein during the mixing process, the surface of the thawed squid viscera granules becomes sticky, and the squid viscera granules use the stickiness to coat the auxiliary powder to form raw material granules, which are fed into a drying mechanism; a powder feeding mechanism for storing and providing auxiliary powder; an air supply mechanism for pneumatically conveying the auxiliary powder provided by the powder feeding mechanism using compressed air and feeding the auxiliary powder into the pelletizing mechanism, and mixing the squid viscera granules and auxiliary powder using compressed air; and a drying mechanism for drying the raw material granules and sterilizing the raw material granules using high temperature.

[0006] Preferably, the crushing mechanism includes a crushing box with an internal crushing chamber. A hopper is located at the bottom of the crushing box, with its upper end connected to the bottom of the crushing chamber. An outlet connected to a granulation mechanism is located at the lower end of the hopper. Two upper crushing rollers are mounted on the upper part of the crushing chamber via two rotating shafts, each with a blade. Two lower crushing rollers are mounted on the lower part of the crushing chamber via two rotating shafts, each with a blade. Blades one and two are arranged perpendicularly. A drive mechanism for the two upper and two lower crushing rollers is mounted on the crushing box. Blade one can be a ring-shaped blade arranged around the upper crushing roller, and blade two can be arranged axially. The straight blade is driven by a geared motor with multiple output shafts. The output shafts of the geared motor are respectively connected to the rotating shafts of the two upper crushing rollers and the two lower crushing rollers. During operation, frozen fresh squid viscera are fed into the crushing chamber of the crushing box. The drive mechanism drives the two upper crushing rollers to rotate relative to each other and the two lower crushing rollers to rotate relative to each other. The two upper crushing rollers cut the squid viscera longitudinally with their blades, and the two lower crushing rollers cut the squid viscera laterally with their blades. At the same time, the two upper crushing rollers and the two lower crushing rollers flatten the squid viscera, thereby cutting and crushing the squid viscera into squid viscera particles of basically the same size. The squid viscera particles are conveyed to the granulation mechanism through the hopper.

[0007] Preferably, it further includes two upper drive wheels concentrically mounted at one end of the shafts of the two upper crushing rollers, and two lower drive wheels concentrically mounted at the two ends of the shafts of the two lower crushing rollers. The upper ends of the two drive belts are respectively fitted onto the two upper drive wheels, and the lower ends of the two drive belts are respectively fitted onto the two lower drive wheels. The upper drive wheels, lower drive wheels, and drive belts constitute a synchronous structure for the upper and lower crushing rollers, so that the upper and lower crushing rollers arranged vertically rotate synchronously. At this time, the drive mechanism only needs to drive one upper crushing roller and one lower crushing roller, thereby simplifying the drive mechanism and improving synchronization.

[0008] Preferably, the granulation mechanism includes: a mixing drum, which has a conical structure and a mixing chamber inside. The lower end of the hopper extends into the upper part of the mixing chamber of the mixing drum. The lower port of the mixing drum is connected to a collection box for collecting raw material particles. An outlet is installed on the collection box for conveying raw material particles to the drying mechanism. An air outlet pipe is installed on the top of the mixing drum, with its input end extending into the top of the mixing chamber of the mixing drum for discharging air. A powder feeding pipe extends into the upper part of the mixing chamber of the mixing drum, with its output end located below the lower end of the hopper. The input end of the powder feeding pipe is connected to a powder feeding mechanism and an air supply mechanism. The powder feeding pipe is used to feed auxiliary powder into the upper part of the mixing chamber of the mixing drum. During operation, the hopper feeds squid viscera particles into the upper part of the mixing chamber of the mixing drum, where they fall downwards. Simultaneously, the air supply mechanism operates, causing the powder feeding pipe to feed the powder feeding mechanism... The provided auxiliary powder is conveyed to the upper part of the mixing chamber of the mixing tank by airflow. Under the action of the airflow, the auxiliary powder mixes with the squid viscera particles, and the auxiliary powder and squid viscera rotate and fall along the conical inner wall of the mixing tank. During the fall, there is a speed difference between the auxiliary powder and the squid viscera particles, which causes them to collide. At the same time, the squid viscera particles gradually thaw, and their surface becomes moist and sticky, causing the auxiliary powder to stick to the surface of the squid viscera particles, thus completing the granulation and forming raw material particles with squid viscera particles as the core. The formed raw material particles fall into the collection box for collection and are conveyed to the drying mechanism through the discharge port. During the conveying process, the raw material particles separate from each other and are prevented from sticking together by the action of the outer auxiliary powder. Excess air in the mixing tank is discharged through the air outlet, completing the preparation of the raw material particles.

[0009] Preferably, it also includes a sieve plate, which is installed at an angle in the collection box, with the lower edge of the sieve plate aligned with the lower edge of the discharge port. The sieve plate can be multi-layered, and multiple sieve plates can perform multi-stage screening of the raw material particles falling into the collection box according to particle size, so that raw material particles of different sizes are conveyed to the drying mechanism through the corresponding discharge port.

[0010] Preferably, the powder feeding mechanism includes a discharge port one, with a storage chamber inside the discharge port one. The output port of discharge port one is connected to the input end of powder pipe one, and the output end of powder pipe one is connected to the input end of powder pipe two. A discharge nozzle is installed at the output end of powder pipe two, and the discharge nozzle is installed inside the powder feeding pipe, with the output end of the discharge nozzle facing the mixing tank. The specific composition of the auxiliary powder is adaptively adjusted according to the specific requirements of the raw materials of the animal feed to be prepared regarding nutritional indicators such as protein content. Commonly used components include plant protein powder, mineral powder, corn flour, and salt. After the components are fully mixed, they are fed into the storage chamber of discharge port one. During operation, the air supply mechanism provides airflow to the powder feeding pipe, creating a negative pressure at the output port of the discharge nozzle. This negative pressure draws out the auxiliary powder from the storage chamber of discharge port one through powder pipe two and powder pipe one, allowing the auxiliary powder to enter the powder feeding pipe and be blown into the mixing chamber of the mixing tank by airflow, thus achieving air-powered feeding.

[0011] Preferably, it also includes a three-way valve and a powder pipe three. The first channel of the three-way valve is connected to the output end of powder pipe one, the second channel of the three-way valve is connected to the input end of powder pipe two, and the third channel of the three-way valve is connected to the output end of powder pipe three. The input end of powder pipe three extends into the bottom of the collection box. After the raw material particles fall into the collection box and are classified and screened by multiple sieve plates, the excess auxiliary powder on the raw material particles will accumulate at the bottom of the collection box. When the auxiliary powder is supplied using outlet one, the three-way valve switches to connect powder pipe one and powder pipe two. When the auxiliary powder at the bottom of the collection box reaches a certain thickness, the three-way valve switches to connect powder pipe three and powder pipe two, so that the auxiliary powder collected at the bottom of the collection box is input into the powder feeding pipe through powder pipe three, the three-way valve, powder pipe two, and the outlet, realizing the recycling of residual material and reducing waste.

[0012] Preferably, the air supply mechanism includes a cabinet-type fan, the air outlet of which is connected to the input end of the powder delivery pipe. A heater is installed at the air outlet of the cabinet-type fan to heat the air output by the cabinet-type fan. The cabinet-type fan absorbs outside air and pressurizes it before inputting it into the powder delivery pipe. The heater heats the airflow to form a high-temperature airflow. The high-temperature airflow pneumatically conveys the auxiliary powder material. In the mixing chamber of the mixing tank, the high-temperature airflow carries the squid viscera particles and auxiliary powder material together for coating and granulation. The high temperature also accelerates the thawing of the squid viscera, improving the coating and granulation effect. The high-temperature airflow is output through the air outlet pipe.

[0013] Preferably, the drying mechanism includes a drying box with an internal drying chamber. The input end of the drying box is connected to a discharge port 1, and the output end of the air outlet extends into the drying chamber of the drying box. Multiple guide plates are obliquely installed in the drying chamber of the drying box. The upper edges of the multiple guide plates are respectively aligned with the lower edges of the multiple discharge ports 1, and the multiple discharge ports 2 are respectively aligned with the multiple discharge ports 2. The multiple discharge ports 2 are installed on the side wall of the drying box. The raw material particles in the collection box are input into the drying chamber of the drying box through the multiple discharge ports 1, and the raw material particles are slid or rolled along the multiple guide plates to the multiple discharge ports 2. During the conveying process, high-temperature airflow is input into the drying chamber of the drying box through the air outlet, and the high-temperature airflow fully contacts the raw material particles, thereby drying the raw material particles and sterilizing them with high temperature. The dried raw material particles are discharged from the drying box through the multiple discharge ports 2.

[0014] The present invention provides a method for preparing raw materials for animal feed using waste squid viscera, comprising: S1, using a crushing mechanism to crush frozen fresh squid viscera into thin sheets and then into squid viscera particles. S2, Input squid viscera particles into the mixing tank; S3, using a high-temperature pneumatic conveying system, the auxiliary powder is fed into the mixing tank by a high-temperature airflow, so that the auxiliary powder and squid viscera particles are fully mixed and contacted. The high-temperature airflow thaws and makes the squid viscera particles sticky, thus sticking the auxiliary powder to form raw material particles with squid viscera particles as the core. The raw material particles are separated from each other, and the outer auxiliary powder prevents them from sticking together. S4, the raw material particles are fed into the drying oven, and the residual heat of the high-temperature airflow in S3 is used to dry and sterilize the raw material particles at high temperature. S5 outputs the dried raw material particles from the drying chamber.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: It adopts a purely physical granulation method, and no longer prepares squid viscera into powder or uses it as a raw material for extracting protein or oil and then uses it for feed preparation. Instead, it uses squid viscera as the core of the raw material pellets for animal feed. Through processes such as freeze crushing, bonding and granulation using the thawing process, drying and high-temperature sterilization, it is directly prepared into raw material pellets for animal feed, which reduces energy consumption and simplifies the process flow, resulting in high work efficiency and good feed particle size.

[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0019] The present invention provides a method for preparing raw materials for animal feed using waste squid viscera, comprising: S1, using the crushing mechanism 1 to crush the frozen fresh squid viscera into thin slices and then into squid viscera particles. S2, feed the squid viscera particles into the mixing tank 13; S3, using a high-temperature pneumatic conveying system, the auxiliary powder is fed into the mixing tank 13 by a high-temperature airflow, so that the auxiliary powder and squid viscera particles are fully mixed and contacted. The high-temperature airflow causes the squid viscera particles to thaw and become sticky, thereby sticking the auxiliary powder to form raw material particles with squid viscera particles as the core. The raw material particles are separated from each other, and the outer auxiliary powder prevents them from sticking together. S4, the raw material particles are fed into the drying chamber 23, and the residual heat of the high-temperature airflow in S3 is used to dry and sterilize the raw material particles at high temperature. S5, output the dried raw material particles from the drying box 23.

[0020] Example 1

[0021] like Figures 1 to 7 As shown, the equipment for preparing animal feed raw materials using waste squid viscera based on the above-mentioned animal feed preparation method includes: a crushing mechanism 1, which crushes frozen fresh squid viscera into granules and feeds the squid viscera granules into a pelletizing mechanism 2; a pelletizing mechanism 2, which mixes auxiliary powder with squid viscera granules. During the mixing process, the surface of the thawed squid viscera granules becomes sticky, and the squid viscera granules use the stickiness to coat the auxiliary powder to form raw material granules, which are then fed into a drying mechanism 5; a powder feeding mechanism 3, which stores and provides auxiliary powder; an air supply mechanism 4, which uses compressed air to pneumatically convey the auxiliary powder provided by the powder feeding mechanism 3 and feeds the auxiliary powder into the pelletizing mechanism 2, and uses compressed air to mix the squid viscera granules and auxiliary powder; and a drying mechanism 5, which dries the raw material granules and sterilizes them using high temperature.

[0022] A purely physical granulation method is adopted, which no longer processes squid viscera into powder or uses it as a raw material for extracting protein or oil for feed preparation. Instead, squid viscera is used as the core of the raw material pellets. Through processes such as freeze crushing, binding and granulation during the thawing process, drying and high-temperature sterilization, it is directly prepared into raw material pellets for animal feed. This reduces energy consumption, simplifies the process, and results in high work efficiency and good feed pellet size.

[0023] Specifically, the crushing mechanism 1 includes a crushing box 6 with an internal crushing chamber, a feeding hopper 7 at the bottom of the crushing box 6, the upper end of the feeding hopper 7 communicating with the bottom of the crushing chamber, and a discharge port connected to the granulation mechanism 2 at the lower end of the feeding hopper 7. Two upper crushing rollers 8 are mounted on the upper part of the crushing chamber of the crushing box 6 via two rotating shafts, and each upper crushing roller 8 has a blade. Two lower crushing rollers 9 are mounted on the lower part of the crushing chamber of the crushing box 6 via two rotating shafts, and each lower crushing roller 9 has a blade. The blades are arranged vertically. A drive mechanism for mounting the two upper crushing rollers 8 and the two lower crushing rollers 9 on the crushing box 6 is also included. The mechanism further includes two upper drive wheels 10 concentrically mounted at the ends of the rotating shafts of the two upper crushing rollers 8, and two lower drive wheels 11 concentrically mounted at the ends of the rotating shafts of the two lower crushing rollers 9. The upper ends of two drive belts 12 are respectively fitted onto the two upper drive wheels 10, and the lower ends of two drive belts 12 are respectively fitted onto the two lower drive wheels 11. The granulation mechanism 2 includes: a mixing tank 13, which has a conical structure and a mixing chamber inside. The lower end of the hopper 7 extends into the upper part of the mixing chamber of the mixing tank 13. The lower port of the mixing tank 13 is connected to a collection box 15 for collecting raw material granules. A discharge port 16 is installed on the collection box 15 for conveying raw material granules to the drying mechanism 5. An air outlet 24 is installed on the top of the mixing tank 13, and the input end of the air outlet 24 extends into the mixing chamber of the mixing tank 13. At the top of the chamber, an air outlet pipe 24 is used to exhaust air; a powder feeding pipe 14 extends into the upper part of the mixing chamber of the mixing tank 13, and the output end of the powder feeding pipe 14 is located below the lower end of the feed hopper 7. The input end of the powder feeding pipe 14 is connected to the powder feeding mechanism 3 and the air supply mechanism 4. The powder feeding pipe 14 is used to feed auxiliary powder into the upper part of the mixing chamber of the mixing tank 13; it also includes a sieve plate 22, which is installed at an angle in the collection box 15, and the lower edge of the sieve plate 22 is aligned with the lower edge of the discharge port 16.

[0024] The first blade can be a ring blade arranged around the upper crushing roller 8, and the second blade can be a straight blade arranged axially. The drive mechanism can be a geared motor with multiple output shafts. The multiple output shafts of the geared motor are respectively connected to the first and second rotating shafts of the two lower crushing rollers 9 of the two upper crushing rollers 8. The upper drive wheel 10, the lower drive wheel 11, and the drive belt 12 constitute a synchronous structure for the upper crushing rollers 8 and the lower crushing rollers 9, so that the upper and lower crushing rollers 8 and 9 arranged vertically rotate synchronously. At this time, the drive mechanism only needs to drive one upper crushing roller 8 and one lower crushing roller 9, thereby simplifying the operation. The drive mechanism improves synchronization; during operation, frozen fresh squid viscera are fed into the crushing chamber of the crushing box 6. The drive mechanism drives two upper crushing rollers 8 to rotate relative to each other, and two lower crushing rollers 9 to rotate relative to each other. The two upper crushing rollers 8 use their blades to longitudinally cut the squid viscera, and the two lower crushing rollers 9 use their blades to transversely cut the squid viscera. At the same time, the two upper crushing rollers 8 and the two lower crushing rollers 9 flatten the squid viscera, thereby cutting and crushing the squid viscera into squid viscera particles of basically the same size. The hopper 7 feeds the squid viscera particles into the mixing tank 13. The mixture falls from the upper part of the chamber downwards, while the air supply mechanism 4 operates, causing the powder supply pipe 14 to convey the auxiliary powder provided by the powder supply mechanism 3 to the upper part of the mixing chamber of the mixing tank 13 by airflow. Under the action of the airflow, the auxiliary powder mixes with the squid viscera particles, and the auxiliary powder and squid viscera rotate and fall along the conical inner wall of the mixing tank 13. During the falling process, there is a speed difference between the auxiliary powder and the squid viscera particles, which causes collisions between them. At this time, the squid viscera particles gradually thaw, and their surface becomes moist and sticky. The auxiliary powder is used to adhere to the surface of the squid viscera particles, thereby completing the granulation and forming raw material particles with the squid viscera particles as the core. The formed raw material particles fall into the collection box 15 for collection. Multiple sieve plates 22 perform multi-stage sieving of the raw material particles falling into the collection box 15 according to particle size, so that raw material particles of different sizes are conveyed to the drying mechanism 5 through the corresponding discharge port 16. During the conveying process, the raw material particles are separated from each other and are prevented from sticking together under the action of the outer auxiliary powder. Excess air in the mixing tank 13 is discharged through the air outlet 24, thus completing the preparation of raw material particles.

[0025] Example 2

[0026] like Figures 1 to 4 , Figure 6 and Figure 8As shown, based on Embodiment 1, the powder feeding mechanism 3 includes a discharge port 16, with a storage chamber inside the discharge port 16. The output port of the discharge port 16 is connected to the input end of the powder pipe 17, and the output end of the powder pipe 17 is connected to the input end of the powder pipe 18. The output end of the powder pipe 18 is equipped with a discharge nozzle 19, which is installed inside the powder feeding pipe 14, and the output end of the discharge nozzle 19 faces the mixing tank 13. It also includes a three-way valve 20 and a powder pipe 21. The first channel of the three-way valve 20 is connected to the output end of the powder pipe 17, the second channel of the three-way valve 20 is connected to the input end of the powder pipe 18, and the third channel of the three-way valve 20 is connected to the output end of the powder pipe 21. The input end of the powder pipe 21 extends into the bottom of the collection box 15.

[0027] The specific composition of the auxiliary powder is adaptively adjusted according to the specific requirements of the raw materials for the animal feed to be prepared regarding nutritional indicators such as protein content. Commonly used components include plant protein powder, mineral powder, corn flour, and salt. After thorough mixing, these components are fed into the storage chamber of discharge port 16. During operation, when the auxiliary powder is supplied through discharge port 16, the three-way valve 20 switches to connect powder pipe 17 and powder pipe 18. The air supply mechanism 4 provides airflow to the powder supply pipe 14, creating a negative pressure at the output port of the discharge nozzle 19. This negative pressure, through powder pipe 18 and powder pipe 17, displaces the auxiliary powder in the storage chamber of discharge port 16. The material is extracted, allowing the auxiliary powder to enter the powder feeding pipe 14 and be blown by air into the mixing chamber of the mixing tank 13, thus achieving pneumatic feeding. After the raw material particles fall into the collection box 15 and are graded and screened by multiple sieve plates 22, the excess auxiliary powder on the raw material particles will accumulate at the bottom of the collection box 15. When the auxiliary powder at the bottom of the collection box 15 reaches a certain thickness, the three-way valve 20 switches to connect the powder pipe 3 21 with the powder pipe 2 18, so that the auxiliary powder collected at the bottom of the collection box 15 is input into the powder feeding pipe 14 through the powder pipe 3 21, the three-way valve 20, the powder pipe 2 18 and the discharge nozzle 19, realizing the recycling of residual material and reducing waste.

[0028] Example 3

[0029] like Figure 6 and Figure 9As shown, based on embodiments 1 and 2, the air supply mechanism 4 includes a cabinet fan 28, the air outlet of the cabinet fan 28 is connected to the input end of the powder supply pipe 14, and a heater 27 is installed at the air outlet of the cabinet fan 28 to heat the air output by the cabinet fan 28; the drying mechanism 5 includes a drying box 23 with an internal drying chamber, the input end of the drying box 23 is connected to the discharge port 16, the output end of the air outlet pipe 24 extends into the drying chamber of the drying box 23, and multiple guide plates 25 are obliquely installed in the drying chamber of the drying box 23. The upper edges of the multiple guide plates 25 are respectively below the output ports of the multiple discharge ports 16, and the lower edges of the multiple guide plates 25 are respectively aligned with the multiple discharge ports 26. The multiple discharge ports 26 are installed on the side wall of the drying box 23.

[0030] A cabinet-type fan 28 absorbs and pressurizes outside air, which is then fed into the powder delivery pipe 14. A heater 27 heats the airflow to form a high-temperature airflow. This high-temperature airflow pneumatically conveys the auxiliary powder material. In the mixing chamber of the mixing tank 13, the high-temperature airflow carries the squid viscera particles and auxiliary powder material together for coating and granulation. The high temperature also accelerates the thawing of the squid viscera, improving the coating and granulation effect. The high-temperature airflow is output through the exhaust pipe 24. The raw material particles in the collection box 15 are fed into the drying chamber of the drying box 23 through multiple discharge ports 16. The raw material particles are then slid or rolled along multiple guide plates 25 to multiple discharge ports 26. During the conveying process, the high-temperature airflow is fed into the drying chamber of the drying box 23 through the exhaust pipe 24. The high-temperature airflow comes into full contact with the raw material particles, thereby drying them, increasing their storage time, and using the high temperature to sterilize them, preventing spoilage and harm to the animals being fed. The dried raw material particles are then discharged from the drying box 23 through multiple discharge ports 26.

[0031] like Figures 1 to 9As shown, the present invention relates to a method and equipment for preparing animal feed using waste squid viscera. During operation, frozen fresh squid viscera are first fed into the crushing chamber of the crushing box 6. Two upper crushing rollers 8 and two lower crushing rollers 9 crush the frozen fresh squid viscera into thin sheets, which are then pulverized into squid viscera particles. These particles are then fed through the hopper 7 into the upper part of the mixing chamber of the mixing tank 13 and fall downwards. Simultaneously, a cabinet-type fan 28 and a three-way valve 20 operate, inputting a high-temperature airflow into the powder feeding pipe 14. This high-temperature airflow provides conveying power for the auxiliary powder, allowing the auxiliary powder in the discharge port 16 to be fed into the powder feeding pipe 14 through the powder pipe 17, powder pipe 28, and discharge nozzle 19. The high-temperature airflow then feeds the auxiliary powder into the mixing chamber of the mixing tank 13. Under the action of the high-temperature airflow, the auxiliary powder and squid viscera particles rotate and descend in the mixing chamber of the mixing tank 13. The high temperature thaws the squid viscera particles, causing them to adhere to the auxiliary powder and form raw material particles with the squid viscera particles as the core. Finally, the raw material particles fall into the collection box 15 and are fed into the drying box 23 through the discharge port 16. At the same time, the high-temperature airflow in the mixing tank 13 is transported to the drying front of the drying box 23 through the air outlet 24, so that the high-temperature airflow dries and sterilizes the raw material particles in the drying box 23. The dried raw material particles are output through the discharge port 26, and the prepared raw material particles are transported to the subsequent process.

[0032] The main functions achieved by this invention are: 1. To address the challenges of processing squid viscera, which are characterized by high moisture content, high viscosity, and easy spoilage, the thawing process is used to bind, encapsulate, and granulate them, directly preparing them as raw material pellets for animal feed. This reduces energy consumption, simplifies the process, increases work efficiency, and produces feed with good particle size. 2. Hot air is used to transport auxiliary powder materials, and residual auxiliary powder materials can be recycled to reduce waste; 3. Based on the principle of cyclone separation, the conical mixing barrel 13 is used for mixing and granulation. By utilizing the swirling flow field inside, the squid viscera particles and auxiliary powders are made to move relative to each other, thereby realizing the core granulation action of "encapsulation". It is simple and efficient, and reduces the mutual adhesion between squid viscera particles. 4. High heat utilization rate of high-temperature airflow: High-temperature airflow is used for cyclone granulation and raw material particle drying, utilizing waste heat and improving energy utilization efficiency, demonstrating innovativeness. The raw material preparation method and equipment for preparing animal feed using waste squid viscera of the present invention are all common mechanical methods in terms of installation, connection, or setting. As long as the beneficial effects can be achieved, they can be implemented. The crushing mechanism 1, granulation mechanism 2, powder feeding mechanism 3, air supply mechanism 4, drying mechanism 5, upper crushing roller 8, lower crushing roller 9, upper transmission wheel 10, lower transmission wheel 11, transmission belt 12, mixing tank 13, discharge port 16, discharge nozzle 19, three-way valve 20, sieve plate 22, drying box 23, guide plate 25, heater 27, and cabinet fan 28 of the raw material preparation method and equipment for preparing animal feed using waste squid viscera of the present invention are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative labor from those skilled in the art.

[0033] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
