Description

Technical Field

[0001] The utility model belongs to the field of pet food processing, and in particular relates to a pet food processing device. Background Art

[0002] With the rapid development of the pet industry, pet food has also begun to diversify. In order to achieve rich nutrition and healthy formulas for pet food, double-blended or multi-blended pet food has begun to be launched, such as double-blended food consisting of beef food and natural grain food. Beef food can provide protein and energy, and natural grain food can provide cellulose, amino acids and other substances to provide balanced nutrition for pets.

[0003] Some pet foods are simply made by mixing two flavors of pre-made pet foods in a certain proportion. Due to the difference in taste and smell between the two pet foods, pets are generally picky eaters when eating ordinary two-flavor pet foods, and only eat one of the pet foods and not the other. Simple two-flavor pet foods cannot achieve the purpose of balanced nutrition.

[0004] Therefore, some double-blended pet food mixes two kinds of food raw materials together, and then expands and shapes them to make double-blended food, so that one grain contains two kinds of food materials at the same time. However, different food raw materials have different expansion temperatures and pressures. During the expansion process of the mixed food raw materials, there is a problem of uneven expansion, some food raw materials cannot be fully expanded, or some food raw materials are over-ripened, resulting in the loss of nutrients.

[0005] Moreover, the existing double-mixed pet food processing devices generally simply stack the two puffed food materials together and shape them by cutting. The puffed food materials will expand, and the two food materials will separate during the expansion process. In addition, after the food materials are dried, the bonding force between the two food materials is reduced, and the double-mixed pet food is more likely to fall off. Utility Model Content

[0006] The utility model provides a pet food processing device to solve the problem of uneven puffing caused by mixing and puffing different food raw materials and the problem of poor pet food forming stability and falling off caused by simply stacking multi-flavor food materials.

[0007] The technical solution adopted by the utility model is:

[0009] The pet food processing device of the utility model also has the following additional technical features:

[0010] The guide surface is provided with spiral protrusions, and a spiral channel for guiding the rotation of the food material is formed between the spiral protrusions.

[0011] The guide member can rotate along a horizontal rotation axis, the angle between the rotation axis of the guide member and the transport direction is less than 90°, and the guide surface cooperates with the transport channel to form a guide channel for food materials to pass through.

[0012] The guide member has a guide channel for accommodating food materials, the guide channel is connected to the transport channel, the inner wall of the guide channel constitutes the guide surface, the guide member can rotate along a horizontal rotation axis, and the rotation axis of the guide member is parallel to the transport direction of the transport channel.

[0014] The transport channel is also provided with a limiting member, which is located on the downstream side of the guide member. The limiting member forms a limiting channel for accommodating food materials, and the size of the limiting channel is smaller than the size of the transport channel.

[0015] Two screws are arranged in each of the puffing bins. The screws include a shaft and screw blades arranged on the shaft. The screw blades of the two screws rotate in opposite directions. The two screws rotate in opposite directions.

[0016] The spiral element is divided into a feeding section, a conveying section and an extruding section located between the feeding section and the conveying section. The pitches of the feeding section and the conveying section are greater than the pitch of the extruding section.

[0017] The forming mechanism also includes a forming member, which includes a transport roller and a matching roller located on the upper side of the transport roller. The transport roller and the matching roller cooperate to extrude the food material located between the transport roller and the matching roller.

[0018] The forming mechanism is provided with an adjusting rod for fixing the matching roller, and the adjusting rod comprises a threaded section and a threaded sleeve, and the threaded section and the threaded sleeve can cooperate to adjust the length of the adjusting rod to adjust the gap between the transport roller and the matching roller.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0020] 1. In the utility model, the puffing mechanism is provided with a plurality of puffing bins for containing food materials, and different puffing bins work independently. The puffing bins are independently set with working parameters such as temperature and pressure to avoid the quality decline of the finished product caused by too low temperature, such as the poor taste, too hardness, lack of toughness of pet food caused by low temperature, and the problems of color distortion caused by too high temperature. Different food materials are placed in different puffing bins, and different powers are set for the spiral parts in different puffing bins according to the different properties of the food materials. Different working temperatures and pressures are set in different puffing bins, so that all food materials can be fully puffed, avoiding the problems of uneven puffing and destruction of nutrients caused by uniform puffing, such as the destruction and loss of temperature-sensitive nutrients such as vitamin B under high temperature and high pressure.

[0021] In addition, the transport channel is connected to the multiple puffing bins, and the puffed food materials from the multiple puffing bins enter the transport channel, forming a multi-flavor food material composed of a combination of multiple food materials. The guide member has a guide surface in contact with the food material, and the guide member can rotate relative to the transport channel. The guide surface can at least produce a partial movement perpendicular to the transport direction, thereby driving the food material to produce a rotational movement perpendicular to the transport direction, forming a twisted structure formed by twisting multiple food materials. The twisted food material structure makes the bonding of multiple food materials more stable. After the food materials are puffed, the expansion force of the food materials is partially converted into an extrusion force between the food materials, which improves the stability of the bonding, improves the stability of the pet food molding, and prevents the pet food from falling off.

[0022] 2. As a preferred embodiment of the present invention, the guide member can rotate along a horizontal rotation axis, the angle between the rotation axis of the guide member and the transport direction is less than 90°, and the guide surface cooperates with the transport channel to form a guide channel for the food material to pass through. The guide member is located on one side of the food material, and the guide surface cooperates with the side wall of the transport channel to form a guide channel. The guide member cooperates with the side wall of the transport channel to squeeze the food material located in the guide channel, so that the adhesion between the various different food materials is more stable. The angle between the rotation axis of the guide member and the transport direction is less than 90°. When the guide member rotates along the rotation axis, the movement of the guide plane can at least be decomposed into a sub-movement perpendicular to the transport direction, thereby driving the food material to produce a twisting motion perpendicular to the transport direction.

[0023] 3. As a preferred embodiment of the present invention, the guide member has an output end located on the downstream side of the transport direction, and a shaping hole is provided on the output end. The guide channel is connected to the transport channel through the shaping hole, and the guide member and the transport channel are detachably connected. The food material guided by the guide space is squeezed into the transport channel through the shaping hole. The shaping hole can change the shape of the food material. For example, the shaping hole is a polygon with edges and corners, and the food material passing through the shaping hole is shaped into angular particles, so that the pet food can have a friction and cleaning effect on the pet's teeth, reducing the occurrence of dental plaque and other diseases. The guide member and the transport channel are detachably connected, and different types of pet food can be produced on a set of the pet food processing device by replacing the guide member with different shaping holes, thereby expanding the production function of the pet food processing device and reducing the investment cost in production equipment due to the expansion of pet food production categories.

[0024] 4. As a preferred embodiment of the present utility model, the spiral element is divided into a feed section, a feeding section, and an extrusion section located between the feed section and the feeding section, and the pitch of the feed section and the feeding section is greater than the pitch of the extrusion section. The feed section at least corresponds to the feed port position of the puffing bin, and the food material falls into the feed section position from the feed port. The pitch of the feed section is greater than the pitch of the extrusion section. The food material is transported downstream under the guidance of the feed section, which can reduce the accumulation of food material in the feed section. The food material is transported under the guidance of the spiral element, and enters the extrusion section from the feed section. The pitch of the extrusion section becomes smaller, which increases the extrusion effect on the food material and improves the puffing effect of the puffing bin. The food material is transported from the extrusion section to the feeding section. The pitch of the feeding section is greater than the pitch of the extrusion section, which reduces the resistance to the transportation of the food material, making it easier for the food material to be output from the puffing bin, reducing the accumulation and adhesion of the food material in the puffing bin.

[0025] 5. As a preferred embodiment of the present invention, the forming mechanism further comprises a forming part, the forming part comprises a transport roller and a matching roller located on the upper side of the transport roller, the forming mechanism is provided with an adjusting rod for fixing the matching roller, the adjusting rod comprises a threaded section and a threaded sleeve, the threaded section and the threaded sleeve cooperate to adjust the length of the adjusting rod to adjust the gap between the transport roller and the matching roller. The transport roller can rotate to provide power for the food material on the upper side of the transport roller to transport backwards, and standardize the transport direction of the food material. The matching roller cooperates with the transport roller to squeeze the food material located between the matching roller and the transport roller, which can increase the adhesion between the food materials, improve the stability of the pet food, and reduce the problem of pet food scattering and dropping. The adjusting rod can adjust the fixed position of the matching roller to adjust the gap between the matching roller and the transport roller, control the thickness of the food material, and control the size of the pet food. For example, the production of larger-sized pet food can reduce the eating speed of large pets to increase the degree of chewing of pet food by pets. The gap between the matching roller and the transport roller can be freely adjusted so that pet food of different sizes can be produced on a set of the pet food processing device according to needs.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0042] like Figure 1 and Figure 5 As shown, a pet food processing device comprises a frame, and a puffing mechanism 1 and a forming mechanism 2 arranged on the frame, wherein the puffing mechanism 1 is provided with a plurality of puffing bins 11 for accommodating food materials, and a spiral member 12 for transporting and extruding food materials is arranged in the puffing bins 11;

[0043] The forming mechanism 2 is provided with a transport channel 21, and the transport channel 21 is connected to the multiple puffing bins 11. The transport channel 21 is provided with a guide member 22, and the guide member 22 has a guide surface 221 in contact with the food material. The guide member 22 can rotate relative to the transport channel 21 so that the guide surface 221 drives the food material to rotate in a direction perpendicular to the transport direction.

[0044] It should be noted that the pet food processing device is used to process multi-flavor pet food, and a grain of multi-flavor pet food has food materials of multiple flavors at the same time. Of course, the pet food processing device can also be used to process single-flavor pet food, and the puffing mechanism 1 is provided with a plurality of puffing bins 11 for accommodating food materials. The design of a plurality of puffing bins 11 can improve the processing efficiency of single-flavor pet food, and the present invention does not limit this.

[0045] The puffing mechanism 1 is provided with a plurality of puffing bins 11 for accommodating food materials, and each puffing bin 11 is provided with a feed port 13. The puffing mechanism 1 is also provided with a hopper 3 and a stirring motor 31 for stirring the food materials in the hopper 3. After the food materials are proportioned, they are stirred evenly in the hopper 3. Each hopper 3 is provided with a feeding port 32 corresponding to the feed port 13, and the food materials stirred evenly by the hopper 3 enter the puffing bin 11 through the feeding port 32 and the feed port 13.

[0046] The different puffing bins 11 work independently, and the working parameters such as temperature and pressure can be set independently to avoid the quality decline of the finished product caused by the temperature in the puffing bin 11 being too high or too low. For example, the pet food may have a poor taste, be too hard, lack toughness, etc. due to the low temperature. It can also avoid the problems of destroying some nutrients and causing color distortion due to excessively high temperature.

[0047] The pet food processing device places different food materials in different puffing bins 11, and sets different powers for the spiral members 12 in different puffing bins 11 according to the different properties of the food materials. Different working temperatures and pressures are set in different puffing bins 11, so that all food materials can be puffed evenly, avoiding the problem of uneven puffing and destruction of nutrients caused by uniform puffing, such as the destruction and loss of temperature-sensitive nutrients such as vitamin B under high temperature and high pressure. At the same time, by controlling the speed of adding food materials in different puffing bins 11 and the transportation speed of food materials in the puffing bins 11, the matching ratio between different food materials can be controlled.

[0048] In addition, the transport channel 21 is connected to the plurality of puffing bins 11, and the puffed food materials in the plurality of puffing bins 11 enter the transport channel 21, forming a multi-flavor food material composed of a plurality of food materials. The guide member 22 has a guide surface 221 in contact with the food material, and the guide member 22 can rotate relative to the transport channel 21, and the guide surface 221 can at least produce a movement perpendicular to the transport direction, thereby driving the food material to produce a rotational movement perpendicular to the transport direction, so that the food material forms a twisted structure formed by twisting a plurality of food materials. The twisted food material structure makes the bonding of a plurality of food materials more stable. After the food materials are puffed, the expansion force of the food materials is partially converted into the extrusion force between the food materials, which improves the stability of the bonding, improves the stability of the pet food molding, and prevents the pet food from falling off.

[0049] It should be noted that the transport channel 21 described in the present invention may refer to a transport pipe or a transport bin, in which a connected transport space is formed, or may refer to a conveyor belt, above which a transport space is formed, in which food materials are transported.

[0050] The pet food processing device may be provided with one transport channel 21, and the transport channel 21 is connected to a plurality of the puffing bins 11. Alternatively, each of the puffing bins 11 is provided with a plurality of discharge ports, and the pet food processing device is provided with a plurality of transport channels 21, and the transport channel 21 is at least connected to at least one discharge port of each of the puffing bins 11, so that pet food can be produced in parallel, thereby improving production efficiency.

[0051] As a preferred embodiment of the present invention, Figure 4 As shown, the guide surface 221 is provided with a spiral protrusion 222, and a spiral channel 223 for guiding the rotation of the food material is formed between the spiral protrusions 222. The spiral protrusions 222 increase the friction between the guide surface 221 and the food material, and increase the force perpendicular to the transportation direction generated by the guide surface 221 on the food material, thereby pushing the food material to produce a rotational motion perpendicular to the transportation direction. The spiral channel 223 for guiding the rotation of the food material is formed between the spiral protrusions 222, and the food material can be transported in rotation along the spiral channel 223, which can reduce the adhesion of the food material on the guide surface 221, reduce the frequency of cleaning the guide 22, and reduce the convenience of using the pet food processing device.

[0052] The present invention does not limit the implementation of the guide member 22, and any one of the following implementations may be adopted:

[0053] In one embodiment, Figure 4 and Figure 5 As shown, the guide member 22 can rotate along the horizontal rotation axis, the angle between the rotation axis of the guide member 22 and the transportation direction is less than 90°, and the guide surface 221 cooperates with the transportation channel 21 to form a guide channel for food materials to pass through. The guide member 22 performs rotational motion, and the guide surface 221 generates a sub-motion perpendicular to the transportation direction. The guide member 22 can drive the food materials in the guide channel 224 to rotate perpendicular to the transportation direction. When the angle between the rotation axis of the guide member 22 and the transportation direction is 0°, the guide surface 221 only performs a motion perpendicular to the transportation direction, and has the strongest guiding ability for the food materials in the guide channel 224. When the angle between the rotation axis of the guide member 22 and the transportation direction is greater than 0° and less than 90°, the guide surface 221 generates a sub-motion perpendicular to the transportation direction and a sub-motion along the transportation direction, which can not only guide the food materials to rotate, but also push the food materials to be transported forward, reducing the accumulation of food materials at the guide member 22.

[0054] In this embodiment, there is no limitation on the positional relationship between the guide member 22 and the food material, and the guide member 22 can be located on the upper side, lower side, or left and right sides of the food material; there is no limitation on the number of the guide members 22, and multiple guide members 22 can be arranged in the transport direction of the transport channel 21, or multiple guide members can be arranged in the circumferential direction of the food material to improve the guiding effect of the food material.

[0055] Embodiment 1: Figure 4 and Figure 5 As shown, the guide member 22 is located above the food material, the guide surface 221 is located on the lower side of the guide member 22, and the guide surface 221 cooperates with the lower side wall of the transport channel 21 to form a guide channel 224. The guide member 22 cooperates with the lower side wall of the transport channel 21 to squeeze the food material located in the guide channel 224. The rotation of the guide member 22 makes the adhesion between the various food materials more stable. The angle between the rotation axis and the transport direction is less than 90°. When the guide member 22 rotates along the rotation axis, the movement of the guide surface can at least be decomposed into a movement perpendicular to the transport direction, thereby driving the food material to produce a twisting movement perpendicular to the transport direction.

[0056] Embodiment 2: The guide member 22 is located below the food material, and the guide surface 221 is located on the upper side of the guide member 22. The food material covers the upper side of the guide surface 221 under the action of gravity, thereby increasing the friction between the food material and the guide surface 221. When the guide member 22 rotates along the rotation axis, the guide surface 221 can more effectively drive the food material to produce a twisting motion.

[0057] Embodiment 3: The transport channel 21 is provided with a guide member 22 on both sides of the food material. The two guide members 22 rotate in opposite directions. Both sides of the food material are guided by the guide surface 221, which is more conducive to the twisting movement of the food material.

[0058] In another embodiment, the guide member 22 has a guide channel for accommodating food materials, the guide channel is connected to the transport channel 21, the inner wall of the guide channel constitutes the guide surface 221, the guide member 22 can rotate along a horizontal rotation axis, and the rotation axis of the guide member 22 is parallel to the transport direction of the transport channel 21. The food materials enter the guide channel through the transport channel 21, the guide member 22 can rotate along a horizontal rotation axis, and the inner wall of the guide channel has a guiding effect on the surrounding side of the food materials, thereby improving the twisting effect of the food materials.

[0059] Specifically, the transport channel 21 is a transport tube, and a connected transport space is formed inside the transport tube. The guide member 22 is sleeved in the transport channel 21. The guide member 22 and the transport channel 21 are fixed by bearings. The guide member 22 can rotate relative to the transport channel 21. A guide channel connected to the transport channel 21 is formed inside the guide member 22.

[0060] Alternatively, the transport channel 21 can be divided into multiple transport sections and guide sections, the transport sections are arranged before and after the guide sections, the guide sections form the guide members 22, the guide sections can rotate relative to the transport sections, the rotation axis of the guide sections is parallel to the transport direction, and a guide channel is formed in the guide sections.

[0061] Preferably, the guide member 22 has an output end located on the downstream side of the transport direction, and a shaping hole is provided on the output end. The guide channel is connected to the transport channel 21 through the shaping hole, and the guide member 22 is detachably connected to the transport channel 21. The food material guided by the guide space is squeezed into the transport channel 21 through the shaping hole. The shaping hole can change the shape of the food material. For example, the shaping hole is a polygon with edges and corners, and the food material passing through the shaping hole is shaped into angular particles, so that the pet food can have a friction and cleaning effect on the pet's teeth, reducing the occurrence of dental plaque and other diseases. The guide member 22 is detachably connected to the transport channel 21, and different types of pet food can be produced on a set of the pet food processing device by replacing the guide member 22 with different shaping holes, so as to expand the production function of the pet food processing device and reduce the investment cost in production equipment due to the expansion of pet food production categories.

[0062] like Figure 4 As shown, the transport channel 21 is further provided with a limiting member 23, which is located on one side of the downstream direction of the guide member 22. The limiting member 23 forms a limiting channel 231 for accommodating food materials, and the size of the limiting channel 231 is smaller than the size of the transport channel 21. The limiting member 23 is located on one side of the downstream direction of the guide member 22, and the food materials enter the limiting channel 231 after passing through the guide channel 224 or the guide channel. The size of the limiting channel 231 is smaller than the size of the transport channel 21. After the food materials are guided by the guide member 22, they twist perpendicularly to the transport direction, and the transport direction of the food materials may change. The side wall of the limiting channel 231 has a limiting effect on the food materials to limit the transport direction of the food materials.

[0063] As a preferred embodiment of the present invention, Figure 2 and Figure 3As shown, two screws 12 are arranged in each puffing bin 11, and the screw 12 includes a shaft and a screw blade 121 arranged on the shaft. The screw blades 121 of the two screws 12 rotate in opposite directions, and the two screws 12 rotate in opposite directions. The two screws 12 in each puffing bin 11 can not only play the role of conveying food materials, but also have the function of stirring and extruding food materials. Two screws 12 are used in each puffing bin 11, that is, a double-screw puffing bin. The food materials are squeezed by the two screws 12, which can improve the puffing efficiency of the puffed food materials. The double-screw puffing bin can improve the puffing efficiency of the food materials by 1.5-2 times compared with the single-screw puffing bin. The rotation directions of the screw blades 121 of the two screw members 12 are opposite, and the rotation directions of the two screw members 12 are opposite, which can better transport the food materials forward, reduce the accumulation of food materials in the gap between the two screw members 12, and avoid the accumulation of food materials causing the screw members 12 to get stuck and stop working.

[0064] Preferably, Figure 3 As shown, the spiral member 12 is divided into a feeding section 122, a feeding section 124, and an extruding section 123 located between the feeding section 122 and the feeding section 124. The pitches of the feeding section 122 and the feeding section 124 are greater than the pitch of the extruding section 123. The feeding section 122 at least corresponds to the position of the feeding port 13 of the puffing bin 11. The food material falls into the feeding section 122 from the feeding port 13. The pitch of the feeding section 122 is greater than the pitch of the extruding section 123. The food material is transported to the downstream direction under the guidance of the feeding section 122, which can reduce the accumulation of the food material in the feeding section 122. The food material is transported under the guidance of the spiral member 12, and enters the extrusion section 123 from the feeding section 122. The pitch of the extrusion section 123 becomes smaller, which increases the extrusion effect on the food material and improves the puffing effect of the puffing bin 11. The food material is transported from the extrusion section 123 to the feeding section 124. The pitch of the feeding section 124 is greater than the pitch of the extrusion section 123, which reduces the resistance to the transportation of the food material, making it easier for the food material to be output from the puffing bin 11, and reducing the accumulation and adhesion of the food material in the puffing bin 11.

[0065] As a preferred embodiment of the present invention, Figure 4 and Figure 5As shown, the forming mechanism 2 also includes a forming member 24, and the forming member 24 includes a transport roller 241 and a matching roller 242 located on the upper side of the transport roller 241, and the transport roller 241 and the matching roller 242 cooperate to squeeze the food material located between the transport roller 241 and the matching roller 242. After the food material flows out of the puffing bin 11, the temperature and pressure decrease rapidly, the food material expands, and the shape of the food material will be deformed to a certain extent. The transport roller 241 and the matching roller 242 cooperate to squeeze the food material located between the transport roller 241 and the matching roller 242, which can not only increase the adhesion between the food materials, improve the stability of the pet food, and reduce the problem of pet food scattering and falling, but also the transport roller 241 and the matching roller 242 cooperate to control the thickness of the food material, reduce the deformation of the food material, and make the formed pet food more in line with production requirements.

[0066] Preferably, the outer peripheral surfaces of the transport roller 241 and the matching roller 242 are inwardly concave shaping surfaces, and the food material passes through the space surrounded by the two shaping surfaces, and the two shaping surfaces cooperate to shape the food material. For example, the food material can be shaped into a bone stick shape as needed to increase the attractiveness of the pet food to the pet dog.

[0067] Preferably, Figure 5 As shown, the forming mechanism 2 is provided with an adjusting rod 25 for fixing the matching roller 242. The adjusting rod 25 includes a threaded section 251 and a threaded sleeve 252. The threaded section 251 and the threaded sleeve 252 cooperate to adjust the length of the adjusting rod 25 to adjust the gap between the transport roller 241 and the matching roller 242. The adjusting rod 25 can adjust the fixed position of the matching roller 242 to adjust the gap between the matching roller 242 and the transport roller 241, control the thickness of the food material, and control the size of the pet food. For example, the production of larger-sized pet food can reduce the eating speed of large pets to increase the degree of chewing of pet food by pets. The gap between the matching roller 242 and the transport roller 241 can be freely adjusted so that pet food of different sizes can be produced on a set of the pet food processing device as needed.

[0068] The present invention does not limit the arrangement of the shearing member 4. Figure 5As shown, in a specific embodiment, the transport channel 21 is provided with two mutually cooperating shearing pieces 4, and the shearing pieces 4 are provided with shearing protrusions 41 at intervals in the circumferential direction. The shearing pieces 4 can rotate relative to the transport channel 21, and the shearing protrusions 41 cooperate at intervals to cut the food material. In this embodiment, the length of the formed pet food can be controlled by controlling the rotation speed of the shearing pieces 4. And the shape of the formed pet food can be changed by controlling the shape of the shearing protrusions 41, such as a crescent-shaped incision.
