Description

Technical Field

[0001] This utility model relates to the field of extrusion equipment technology, specifically to a low-temperature extrusion device for improving the texture of protein bars. Background Technology

[0002] Protein bars, as a convenient high-protein nutritional supplement, have seen continuous growth in market demand in recent years due to their ability to quickly replenish the protein needed by the human body and their suitability for fitness, meal replacement, and other scenarios. The production process of protein bars requires the use of low-temperature extrusion equipment to achieve molding and extrusion. However, the existing low-temperature extrusion equipment for protein bars still has certain defects in its use.

[0003] For example, the extrusion device for processing walnut protein bars proposed in application number CN202323381933.3 relates to the field of walnut protein bar processing technology. It includes a processing device body suitable for protein bar production and processing. The processing device body includes a base, a lower mold fixedly installed on the top of the base, support columns fixedly installed around the top of the base, a top plate welded to the top of the support columns, and a raw material barrel fixedly installed on the top of the top plate. An extrusion unit is provided inside the raw material barrel. In actual use, this walnut protein bar extrusion device directly utilizes the descent of the extrusion disc in conjunction with the mold groove to achieve the forming and extrusion work when extruding the protein bar raw material. However, the raw material is prone to uneven mixing before extrusion, resulting in uneven texture in the protein bars and reducing their effectiveness. In the prior art, a separate stirring device may be used for uniform mixing before the extrusion process, which complicates the process and reduces production efficiency.

[0004] Therefore, we propose a low-temperature extrusion device to improve the texture of protein bars, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a low-temperature extrusion device that improves the texture of protein bars, in order to solve the problems mentioned in the background art. Existing extrusion devices for processing walnut protein bars directly form the bars by lowering the extrusion plate and forming them with the mold groove. This results in uneven mixing of raw materials, leading to poor texture of the protein bars. Adding a separate stirring device would increase the complexity of the process and reduce production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-temperature extrusion device for improving the texture of protein bars, comprising a shell, positioning seats fixedly installed at both ends of the shell, support seats symmetrically installed between the positioning seats, the inner side of the support seats being fixedly connected to the surface of the shell, and support frames fixedly installed at the bottom of both support seats.

[0007] The top of the outer casing is symmetrically equipped with a feeding guide mechanism;

[0008] The shell is equipped with a dispersion extrusion mechanism, the bottom of which is connected to a conveying pipe, and the discharge end of the conveying pipe is fixedly connected to a discharge forming mechanism.

[0009] Preferably, the feeding guide mechanism includes a feeding hopper movably mounted on the top of the housing, a positioning screw connecting the feeding hopper to the housing and the support base, and a discharge port installed at the bottom front end of the feeding hopper, which is connected to the housing.

[0010] Preferably, the inner bottom surface of the feed hopper slopes from the rear end towards the discharge port.

[0011] The above-mentioned structural design, with its inclined bottom surface inside the feed hopper, allows the raw materials to flow naturally towards the discharge port by gravity, preventing them from accumulating and stagnating inside the feed hopper. The positioning screw can firmly fix the relative position of the feed hopper, the outer shell, and the support base, preventing feed deviation caused by equipment vibration during the feeding process. This lays the foundation for uniform mixing of raw materials and improvement of texture, while also facilitating the disassembly and maintenance of the feed hopper.

[0012] Preferably, the dispersing extrusion mechanism includes a fixed block fixedly installed inside the rear end of the housing. A transmission rod is symmetrically arranged at the top of the inner end of the housing. A stirring rod is installed at equal intervals around the outer ring of the transmission rod. The rear end of the transmission rod is rotatably connected to the fixed block. The two ends of the transmission rod are rotatably connected to the positioning seats at the front and rear ends. A first servo motor is connected to the front end of the transmission rod. The first servo motor is fixedly connected to the positioning seat at the front end.

[0013] Preferably, the dispersive extrusion mechanism further includes extrusion screws symmetrically arranged at the bottom of the inner shell. The two ends of the extrusion screws are rotatably connected to the positioning seats at the front and rear ends. A second servo motor is connected to the front end of the extrusion screws. The second servo motor is fixedly connected to the front positioning seat. A partition seat is provided between the extrusion screws. The bottom surface of the partition seat is fixedly connected to the outer shell. A conveying groove is symmetrically opened at the bottom of the fixed block. The conveying groove fits against the outer ring of the rear end of the extrusion screw. A discharge hopper is fitted into the bottom of the rear end of the conveying groove. The discharge hopper is connected through to the bottom of the rear end of the outer shell.

[0014] With the above-mentioned structural design, the transmission rod, in conjunction with the equally spaced stirring rods, rotates at high speed under the drive of the first servo motor. This fully stirs and disperses the raw materials entering the shell, effectively solving the problem of uneven mixing of raw materials in traditional equipment. This provides a prerequisite for improving the texture of protein bars. The extrusion screw, driven by the second servo motor, achieves low-temperature extrusion and conveying. Together with the front-end stirring structure, it forms an integrated "stirring-extrusion" design, eliminating the need for additional stirring equipment, simplifying the production process, and significantly improving production efficiency.

[0015] The separator prevents mutual interference between the two extrusion screws during operation. The fit design between the conveying trough and the outer ring of the extrusion screw ensures stable material delivery. The discharge hopper guides the mixed material into the conveying pipe, ensuring the continuity and stability of the processing flow.

[0016] Preferably, the discharge forming mechanism includes a diverter seat fixedly installed at the discharge end of the conveying pipe, the two ends of the diverter seat being fixedly connected to the two positioning seats, and a discharge mold being fixedly installed at the bottom of the diverter seat.

[0017] With the above-mentioned structural design, the diversion seat can evenly distribute the raw materials conveyed by the conveying pipe to the discharge mold. The protein bars are formed in a regular manner through the forming channel of the discharge mold, ensuring that the finished protein bars have uniform shape and size, and further improving the product's appearance and textural stability.

[0018] Preferably, the discharge forming mechanism includes a diverter seat fixedly installed at the discharge end of the conveying pipe. The two ends of the diverter seat are fixedly connected to the two positioning seats. A discharge mold is movably installed at the bottom of the diverter seat. Connecting plates are fixedly installed at both ends of the discharge mold. An adjusting screw is threaded through the internal thread of the connecting plate. A turntable is fixedly sleeved on the outer end of the adjusting screw. Positioning grooves are opened at both ends of the diverter seat. The positioning grooves are engaged with the inner end of the adjusting screw.

[0019] With the above-mentioned structural design, rotating the turntable drives the adjusting screw to rotate. Combined with the engagement of the connecting plate and the positioning groove, the discharge mold can be flexibly replaced to adapt to the production needs of protein bars with different diameters and thicknesses, improving the versatility of the equipment. After installation, the discharge mold is fixed by the engagement of the positioning groove and the adjusting screw, ensuring the structural stability during the molding process and broadening the applicable scenarios of the equipment.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the low-temperature extrusion equipment for improving the texture of protein bars;

[0021] 1. By optimizing the feeding and dispersing extrusion structure, the texture of protein bars is effectively improved and production efficiency is increased. In the feeding guide mechanism, the inclined bottom of the feeding hopper guides the raw material to flow naturally and avoids accumulation. The positioning screw ensures stable feeding and lays the foundation for subsequent processing. The stirring rod of the dispersing extrusion mechanism fully disperses the raw material under the drive of the motor, solving the problem of uneven mixing. Together with the extrusion screw, it forms an integrated "stirring-extrusion" design, eliminating the need for separate stirring equipment, simplifying the process, and ensuring the uniformity of raw material mixing, providing a prerequisite for high-quality texture. The conveying trough and partition seat and other structures ensure continuous and stable raw material conveying.

[0022] 2. The discharge molding mechanism further enhances the practicality of the equipment and the stability of product quality. In the basic design, the flow divider evenly distributes the raw materials to the discharge mold, ensuring that the protein bars have uniform shape and size, and enhancing the stability of appearance and texture. The design of the replaceable discharge mold allows for flexible replacement by adjusting the screw and turntable, adapting to the production of products of different specifications and improving the versatility of the equipment. The locking and fixing of the positioning groove and the adjusting screw ensures the stability of the molding process and broadens the applicable scenarios of the equipment.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a low-temperature extrusion device for improving the texture of protein bars, including a shell 1, with positioning seats 2 fixedly installed at both ends of the shell 1, and support seats 3 symmetrically installed between the positioning seats 2. The inner side of the support seats 3 is fixedly connected to the surface of the shell 1, and support frames 19 are fixedly installed at the bottom of both support seats 3. A feeding guide mechanism is symmetrically installed on the top of the shell 1. The feeding guide mechanism includes a feeding hopper 4 movably installed on the top of the shell 1. A positioning screw 5 is connected between the feeding hopper 4, the shell 1, and the support seats 3. A discharge port 6 is installed at the bottom of the front end of the feeding hopper 4. The discharge port 6 is connected to the shell 1. The inner bottom surface of the feeding hopper 4 is inclined from the rear end to the discharge port 6.

[0034] The above-mentioned structure is designed to provide stable support through the support frame 19 at the bottom of the two side support seats 3. The positioning seats 2 at both ends of the outer shell 1 are fixedly connected to the support seats 3, which together provide a stable installation foundation for the outer shell 1 and its components. When the raw material is conveyed, the protein bar raw material is added into the feed hopper 4. Since the bottom surface of the feed hopper 4 is inclined from the rear end to the discharge port 6, the raw material will naturally flow towards the discharge port 6 under its own gravity, avoiding accumulation and retention in the feed hopper 4. Then the raw material enters the inner shell 1 through the discharge port 6, completing the feeding process. During this process, the positioning screw 5 connecting the feed hopper 4, the outer shell 1, and the support seat 3 plays a stabilizing role, which can effectively prevent the position of the feed hopper 4 from shifting due to vibration during equipment operation, ensuring that the raw material continuously and stably enters the outer shell 1, providing a stable supply of raw materials for subsequent dispersion, mixing, and extrusion processing. During subsequent maintenance, the feed hopper 4 can be disassembled and cleaned by rotating and disassembling the positioning screw 5.

[0035] The housing 1 is equipped with a dispersion extrusion mechanism. The dispersion extrusion mechanism includes a fixed block 7 fixedly installed inside the rear end of the housing 1. A transmission rod 8 is symmetrically arranged at the top inside the housing 1. A stirring rod 9 is evenly spaced on the outer ring of the transmission rod 8. The rear end of the transmission rod 8 is rotatably connected to the fixed block 7. Both ends of the transmission rod 8 are rotatably connected to the front and rear positioning seats 2. A first servo motor 10 is connected to the front end of the transmission rod 8. The first servo motor 10 is fixedly connected to the front positioning seat 2. The dispersion extrusion mechanism also includes extrusion rods symmetrically arranged at the bottom inside the housing 1. The screw 11 is rotatably connected to the front and rear positioning seats 2 at both ends. The front end of the screw 11 is connected to the second servo motor 12, which is fixedly connected to the front positioning seat 2. The screw 11 is provided with a partition seat 13 between the screws. The bottom surface of the partition seat 13 is fixedly connected to the outer shell 1. The bottom of the fixing block 7 is symmetrically provided with a conveying groove 14. The conveying groove 14 fits against the outer ring of the rear end of the screw 11. The bottom of the rear end of the conveying groove 14 is fitted with a discharge hopper 15, which is connected to the bottom of the rear end of the outer shell 1.

[0036] With the above-described structure, after the raw material enters the shell 1, the dispersion extrusion mechanism starts to work: the first servo motor 10 fixed on the front positioning seat 2 starts and drives the transmission rod 8 connected to it to rotate. Since the two ends of the transmission rod 8 are rotatably connected to the front and rear positioning seats 2 and the rear end is rotatably connected to the fixed block 7 inside the rear end of the shell 1, the transmission rod 8 is guaranteed to rotate stably. The stirring rods 9, which are installed at equal intervals on the outer ring of the transmission rod 8, rotate synchronously with it to fully stir and disperse the raw material entering the shell 1, thus solving the problem of uneven mixing of raw materials.

[0037] After mixing, the raw material accumulates at the bottom of the inner shell 1. The second servo motor 12 fixed on the front positioning seat 2 drives the extrusion screw 11 to rotate. The two ends of the extrusion screw 11 are rotatably connected to the front and rear positioning seats 2 to ensure stable rotation. The partition seat 13 between the two extrusion screws 11 prevents them from interfering with each other during operation. The raw material is conveyed backward under the rotation of the extrusion screw 11. During the process, the conveying groove 14 symmetrically opened at the bottom of the fixed block 7 fits against the outer ring of the rear end of the extrusion screw 11 to ensure stable conveying of the raw material to the rear end. Finally, it is sent out to the conveying pipe 16 through the discharge hopper 15 installed at the bottom of the rear end of the conveying groove 14, completing the dispersion and extrusion conveying process.

[0038] The bottom of the dispersive extrusion mechanism is connected to a conveying pipe 16, and the discharge end of the conveying pipe 16 is fixedly connected to a discharge forming mechanism. The discharge forming mechanism includes a flow divider 17 fixedly installed at the discharge end of the conveying pipe 16. Both ends of the flow divider 17 are fixedly connected to the two end positioning seats 2, and the bottom of the flow divider 17 is fixedly installed with a discharge mold 18.

[0039] In the above-described structure, the raw material processed by the dispersive extrusion mechanism is transported through the conveying pipe 16 connected to its bottom. The conveying pipe 16 guides the raw material into the diverter seat 17 fixedly connected to its discharge end. Since the two ends of the diverter seat 17 are fixedly connected to the two end positioning seats 2, it can ensure that the diverter seat 17 maintains structural stability during the raw material transportation process. The diverter seat 17 will evenly distribute the transported raw material into the discharge mold 18 fixedly installed at its bottom. The raw material completes the final molding in the molding channel of the discharge mold 18, forming a protein bar with a regular shape, thereby completing the entire extrusion molding process.

[0040] Example 2: Based on Example 1, this utility model adopts the following... Figure 7-8 The technical solution shown further discloses that the discharge forming mechanism includes a diverter seat 17 fixedly installed at the discharge end of the conveying pipe 16. The two ends of the diverter seat 17 are fixedly connected to the two end positioning seats 2. The bottom of the diverter seat 17 is movably installed with a discharge mold 18. The two ends of the discharge mold 18 are fixedly installed with connecting plates 20. The internal threads of the connecting plates 20 pass through an adjusting screw 21. The outer end of the adjusting screw 21 is fixedly sleeved with a turntable 22. The two ends of the diverter seat 17 are provided with positioning grooves 23. The positioning grooves 23 are engaged with the inner end of the adjusting screw 21.

[0041] The above-described structure guides the raw material evenly to the dispensing mold 18, which is movably installed at its bottom, to form protein bars. When different specifications of protein bars need to be produced, the turntable 22 on the connecting plates 20 at both ends of the dispensing mold 18 can be rotated to drive the adjusting screw 21 that passes through the connecting plates 20 to rotate. This disengages the adjusting screw 21 from the positioning grooves 23 at both ends of the dispensing mold 17, allowing the current dispensing mold 18 to be removed and replaced with a new dispensing mold 18 of the appropriate specification. After replacement, the turntable 22 is rotated in the opposite direction to re-engage the adjusting screw 21 with the positioning groove 23, thereby firmly fixing the new dispensing mold 18 at the bottom of the dispensing mold 17. This ensures the stability of the dispensing mold 18 during the forming process and meets the production needs of protein bars of different specifications.

[0042] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
