Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cat food puffing, in particular to a microporous puffing machine for fresh meat cat food. Background Art
[0002] The expanded pellet feed is processed by the extruder, which increases the feed flavor and palatability, stimulates the animal's appetite, and improves the digestibility of protein and fat. The extruder integrates multiple functions such as mixing, shearing, and heating. Its working principle is to convert mechanical energy into thermal energy. The raw materials are driven by twin screws and suddenly decompressed after heating and pressurization to achieve the expansion effect. The structure includes a conditioner, a bearing box, an extrusion and expansion mechanism, an extrusion die, and a cutter mechanism, which are used for material conditioning, main machine support, material transportation and extrusion, expansion, and cutting. Finally, the expanded feed is cut into specified sizes and formed by drying equipment.
[0003] At present, in order to meet the intestinal digestion needs of cats, a new technology that can effectively destroy the structure of cat food has emerged. The purpose of this technology is to ensure that during the heating process, steam can smoothly penetrate the outer wall of the cat food and penetrate into its interior, thereby reducing the moisture content, breaking its originally tight internal structure, and forming a clear porous structure, thereby significantly improving the crispness of the cat food. The fresh meat cat food microporous extruder described in the Chinese utility model patent document with announcement number CN218354519U attempts to achieve the above goal by setting a conical protrusion structure on the extrusion channel and the surface of the tool.
[0004] However, this design has exposed significant defects in practical applications. Since the conical spike structure is a decentralized design, they cannot form a coherent and complete cat food destruction mechanism. As a result, during the extrusion and cutting process of the cat food, the cat food will be continuously affected by the coherent and complete mechanism of the conical spike structure, forming pits of different sizes and shapes. Although this design does help to open the tight structure of the cat food, it also makes it difficult for the cat food to maintain its complete shape, and the overall appearance is relatively crushed.
[0005] In addition, since the cone structures are dispersed, there is no continuous channel between them, which brings great challenges to the cleaning of the equipment. Once a large amount of residue is produced during the processing of cat food, these residues are easily accumulated between the cone structures, making subsequent cleaning extremely difficult. This not only increases the maintenance cost of the equipment, but may also affect the normal operation of the equipment and the production quality of cat food.
[0006] Therefore, it is very necessary to invent a microporous puffing machine for fresh meat cat food. Utility Model Content
[0007] In order to solve the above technical problems, the utility model provides a fresh meat cat food microporous puffing machine, comprising a puffing machine mold, a base plate, a self-cleaning mechanism and a pressure dividing body, wherein the base plate is fixedly installed on the outside of the puffing machine mold, and the self-cleaning mechanism is fixedly installed on the base plate; the puffing machine mold is fixedly installed at the discharge of the puffing machine, and the pressure dividing body is fixedly installed inside the puffing machine mold;
[0008] The extruder mold comprises a discharging mold, a main discharging cavity, a discharging port, a surface destroying body, a knife disc, a cutting knife and a cross-section destroying body.

The motor output end built into the discharging mold is fixed with the knife disc, and a plurality of the cutting knives are fixedly installed on the outside of the knife disc, and the cross-section destroying body is provided on the outer surface of the cutting knife;
[0009] The self-cleaning mechanism includes a base, a rotating shaft arm, a servo motor, a superimposed plate and a cleaning plate. The base is fixedly mounted on the substrate; the rotating shaft arm rotatably mounted on the base is fixed to the output end of the servo motor, and the servo motor is fixedly mounted on the base through a support plate; the rotating shaft arm is fixedly connected to the superimposed plate, and the cleaning plate is provided on the inner surface of the superimposed plate.
[0010] Preferably, the pressure dividing body is a conical boss structure with a round surface, the pressure dividing body is arranged in the main discharge cavity of the discharge mold, and the discharge ports are arranged around the pressure dividing body.
[0011] Preferably, the inner wall of the discharge port is provided with a plurality of surface-destroying bodies, the cross-section of which is a triangular structure, the surface-destroying bodies have a spiral angle of not less than three degrees, and spiral linear grooves are formed between the surface-destroying bodies.
[0012] Preferably, the blade bevel of the cutting knife is not less than forty-five degrees, the section destroying body is inclinedly arranged at the blade of the cutting knife, the cross section of the section destroying body is triangular, and the cat food can smoothly transition from the blade bevel of the cutting knife to the section destroying body.
[0013] Preferably, the servo motor drives the rotating shaft arm to control the overlapping plate to move away from or close to the cutting knife. The cutting knife is parallel to the overlapping plate. The cleaning plate arranged on the inner surface of the overlapping plate is allowed to contact the blade surface of the cutting knife. The cleaning plate is a cleaning structure made of highly elastic and wear-resistant polymer material.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] The utility model completely abandons the traditional scattered layout design and introduces innovative surface destroyers and cross-section destroyers with triangular cross-sections. This design is capable of forming a coherent and complete destruction processing mechanism, ensuring that the raw materials can be destroyed evenly and orderly during the cat food extrusion process, thereby avoiding the problem of the cat food being difficult to shape due to excessive destruction.
[0016] It is worth mentioning that the surface destroyer also incorporates a specific spiral angle design. This unique design allows the cat food to form more complex and rich grooves and textures during the puffing process, thereby greatly increasing the surface area of the material. This change not only enhances the appearance of the cat food, but more importantly, during the heating process, the larger surface area helps to improve the heat exchange efficiency, thereby speeding up the drying process and improving production efficiency.
[0017] In addition, the utility model is also equipped with a self-cleaning mechanism. This innovative design significantly improves the usability and maintainability of the equipment. When the cat food is not puffed and cut, the self-cleaning mechanism can automatically handle the residues between the broken bodies on the cutting knife, greatly reducing the burden of manual cleaning, while also improving the working efficiency and stability of the equipment.

[0025] As attached Figure 1 To Attachment Figure 3 As shown:
[0026] The utility model provides a microporous puffing machine for fresh meat cat food, comprising a puffing machine mould 1, a base plate 2, a self-cleaning mechanism 3 and a pressure dividing body 4. The base plate 2 is fixedly mounted on the outside of the puffing machine mould 1, and the self-cleaning mechanism 3 is fixedly mounted on the base plate 2; the puffing machine mould 1 is fixedly mounted at the discharge of the puffing machine, and the pressure dividing body 4 is fixedly mounted on the inside of the puffing machine mould 1.
[0027] The extruder mold 1 includes a discharge mold 11, a main discharge cavity 12, a discharge port 13, a surface destroying body 14, a knife disc 15, a cutting knife 16 and a cross-section destroying body 17. The discharge mold 11 is fixedly installed at the discharge of the extruder, and the base plate 2 and the pressure dividing body 4 are fixedly installed on the outside and inside of the discharge mold 11 respectively; the discharge mold 11 is provided with the main discharge cavity 12 and the discharge port 13, and the inner wall of each discharge port 13 is provided with a plurality of surface destroying bodies 14. The motor output end built into the discharge mold 11 is fixed to the knife disc 15, and a plurality of cutting knives 16 are fixedly installed on the outside of the knife disc 15, and the outer surface of the cutting knife 16 is provided with the cross-section destroying body 17. The extruder mold 1 can form a coherent and complete destruction processing mechanism to ensure that the raw materials can be destroyed evenly and orderly during the extrusion process of the cat food, thereby avoiding the problem that the cat food is difficult to form due to excessive destruction.
[0028] The self-cleaning mechanism 3 includes a base 31, a rotating shaft arm 32, a servo motor 33, a superimposed plate 34 and a cleaning plate 35. The base 31 is fixedly mounted on the base plate 2; the rotating shaft arm 32 rotatably mounted on the base 31 is fixed to the output end of the servo motor 33, and the servo motor 33 is fixedly mounted on the base 31 through a support plate; the rotating shaft arm 32 is fixedly connected to the superimposed plate 34, and the inner surface of the superimposed plate 34 is provided with the cleaning plate 35. When the self-cleaning mechanism 3 is not cutting the cat food puffing, the self-cleaning mechanism can automatically handle the residues between the cross-section destroying bodies on the cutting knife, which greatly reduces the burden of manual cleaning and also improves the working efficiency and stability of the equipment.
[0029] Embodiment 1:
[0030] Specifically, the pressure dividing body 4 is a conical boss structure with a round surface, and the pressure dividing body 4 is arranged in the main discharge cavity 12 of the discharge mold 11, and the discharge port 13 is arranged around the pressure dividing body 4. The cat food raw materials can be evenly squeezed and pushed out under the action of the pressure dividing body 4, while ensuring the consistency of the shape and size of the cat food particles. In addition, the layout of the discharge port 13 also takes into account the fluidity and puffing effect of the cat food, ensuring that the final product can meet the digestion needs and taste preferences of cats.
[0031] Specifically, a plurality of surface destroyers 14 are provided on the inner wall of the discharge port 13, and the cross-sections of these surface destroyers 14 are designed to be triangular, so as to achieve effective destruction and shaping effects during the cat food extrusion process. More importantly, these surface destroyers 14 not only have triangular cross-sections, but also have a spiral angle of not less than three degrees, so that the cat food can form spiral linear grooves and textures when passing through the discharge port 13. These grooves and textures not only increase the surface area of the cat food particles, which helps to achieve more efficient heat exchange and drying during the heating process, but also improve the taste and attractiveness of the cat food, and spiral linear grooves will be formed between the surface destroyers 14.
[0032] Specifically, the blade bevel of the cutting knife 16 is not less than 45 degrees, and the section destroying body 17 is inclinedly arranged at the blade of the cutting knife 16. When the cat food is cut by the cutting knife 16, it can smoothly transition from the blade bevel to the section destroying body 17. Since the section of the section destroying body 17 is triangular and has a proper inclination angle, it can further destroy and shape the section of the cat food, increase the surface area of the cat food and form a complex texture structure, which not only improves the cutting effect of the cat food and ensures the uniformity and consistency of the particles, but also creates better conditions for the subsequent puffing process.
[0033] Embodiment 2:
[0034] Specifically, the present design introduces a servo motor 33 to control the movement of the shaft arm 32, thereby adjusting the distance between the stacking plate 34 and the cutting knife 16. When the servo motor 33 is working, it can drive the shaft arm 32 to rotate, so that the stacking plate 34 is away from or close to the cutting knife 16. This design allows the position of the stacking plate 34 to be adjusted according to actual needs to accommodate cat food particles of different sizes or types.
[0035] The cutting blade 16 is arranged parallel to the overlapping plate 34. This design ensures that the cat food can be evenly stressed during the rotation process and avoids the situation where the residue is difficult to handle due to uneven stress.
[0036] A cleaning plate 35 is provided on the inner surface of the stacking plate 34, and the cleaning plate 35 is designed to be in contact with the blade surface of the cutting knife 16. The cleaning plate 35 is made of a highly elastic and wear-resistant polymer material, which not only has good wear resistance and can maintain stable performance during long-term use, but also has sufficient elasticity and can closely fit the blade surface of the cutting knife 16, thereby effectively removing residues on the blade.
[0037] Embodiment three:
[0038] First, the cat food raw materials are preliminarily processed inside the extruder and then enter the extruder mold 1. The pressure dividing body 4 inside the mold is designed as a conical boss structure with a round surface, which is installed in the main discharge cavity 12 and surrounded by a discharge port 13. Under the action of the pressure dividing body 4, the cat food raw materials are uniformly squeezed and pushed out to form preliminary cat food particles.
[0039] On the inner wall of the discharge port 13, there are several surface destroying bodies 14. The cross-section of these surface destroying bodies 14 is triangular and has a spiral angle of not less than three degrees. When the cat food particles pass through the discharge port 13, the surface destroying bodies 14 will destroy and shape their surface, forming spiral linear grooves and textures. These grooves and textures not only increase the surface area of the cat food particles, promote heat exchange and drying efficiency during the heating process, but also improve the taste and attractiveness of the cat food.
[0040] Subsequently, the cat food particles are cut by the cutting knife 16 on the knife disc 15. The blade bevel of the cutting knife 16 is not less than 45 degrees, which ensures the stability of the cutting and the integrity of the particles. At the same time, the section destroying body 17 is inclined at the blade of the cutting knife 16 to further destroy and shape the section of the cat food, forming a more complex texture structure.
[0041] In order to keep the equipment clean and running stably, the utility model also introduces a self-cleaning mechanism 3, which cleans the cat food when it is not puffed. The mechanism drives the rotating shaft arm 32 to move through the servo motor 33, so that the stacking plate 34 is close to or away from the cutting knife 16. The cleaning plate 35 on the inner surface of the stacking plate 34 contacts the blade surface of the cutting knife 16, and the cleaning plate 35 made of highly elastic and wear-resistant polymer material is used to remove the residue on the blade. This design greatly reduces the burden of manual cleaning and improves the working efficiency and stability of the equipment.
[0042] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
