Abstract
Description
Technical Field
[0001] This application relates to the field of food processing machinery technology, and in particular to a spiral enema device for uniform mixing of polypeptides. Background Technology
[0002] Currently, in the processing of functional surimi products, the addition of active peptides has become a key means to enhance the nutritional value of the products. However, due to their high surface energy and strong intermolecular forces, bioactive substances such as cod gelatin antifreeze peptides are prone to agglomeration during traditional stirring and mixing. The industry generally adopts high-speed shear emulsification or the addition of dispersants to improve the mixing effect, but the former will lead to the destruction of peptide structure, while the latter may introduce chemical residues.
[0003] Regarding the aforementioned technologies, existing traditional paddle mixers have dead zones, leading to localized excessive peptide concentrations. This results in poor uniformity in peptide mixing, reduces peptide quality, and causes many inconveniences for users. Utility Model Content
[0004] The purpose of this application is to provide a spiral enema device for uniform mixing of peptides, which has the advantages of improving the uniformity of peptide dispersion and solves the problems mentioned in the background art.
[0005] The spiral enema device for uniform mixing of polypeptides provided in this application adopts the following technical solution: it includes a box, a feeding mechanism, a spiral mixing mechanism, and a filling mechanism. The spiral mixing mechanism includes a drive motor fixedly installed at the bottom of the box via a mounting bracket. Bearings are fixedly connected to the top and bottom of the box. A rotating shaft is rotatably connected inside each of the two bearings. The bottom end of the rotating shaft is fixedly connected to the output shaft of the drive motor. Several primary screws, intermediate screws, and final screws are fixedly connected to the surface of the rotating shaft. The primary screws, intermediate screws, and final screws are three-stage variable diameter screws.
[0006] The stirring core of the spiral mixing mechanism consists of a three-stage variable diameter screw. The diameter and pitch of the primary screw, intermediate screw and final screw decrease step by step. The primary screw, intermediate screw and final screw are all made of stainless steel and the surface is mirror polished.
[0007] By adopting the above technical solution and setting up a spiral mixing mechanism, the drive motor can drive the rotating shaft to rotate. The primary screw, with a smaller diameter and pitch, rapidly propels the material downwards while generating initial stirring. As the screw diameter and pitch gradually increase, the material is gradually compressed, and the shear force is enhanced, achieving fine mixing. At the same time, the three-stage variable diameter design ensures that the material is subjected to different intensities of mechanical action at different stages—the primary screw is responsible for rapid conveying and fine mixing, the intermediate screw strengthens shear dispersion, and the final screw achieves uniform extrusion through a larger diameter and pitch, avoiding local agglomeration. The mirror-polished stainless steel surface is smooth and without dead corners, reducing material adhesion, preventing peptide residue and deterioration, and facilitating cleaning and disinfection.
[0008] Preferably, the feeding mechanism includes a metering belt scale fixedly installed on the top of the box, two feeding boxes are fixedly connected to the top of the box, a sealing cover is movably connected to the top of the feeding box via a hinge, and a handle is fixedly connected to the top of the sealing cover.
[0009] By adopting the above technical solution and setting up a feeding mechanism, the metering belt scale can pre-weigh the raw materials proportionally, and then the data can be observed by the PLC programmable controller, avoiding errors caused by manual feeding and ensuring the consistency of the mixing ratio. It is especially suitable for the standardized production of peptide formulations. The sealed cover of the feeding box prevents material dust from escaping or external contamination. The handle facilitates manual feeding, the hinge design supports quick opening and closing, and the sealing design prevents material volatilization or reaction with air, protecting operators from dust hazards.
[0010] Preferably, the filling mechanism includes two metering pumps fixedly installed at the bottom of the box, with a discharge pipe fixedly connected to the bottom end of each metering pump, and a filling head fixedly connected to one end of the discharge pipe.
[0011] By adopting the above technical solution and setting up a filling mechanism, the output flow rate can be precisely controlled by a metering pump according to the instructions of a PLC programmable controller, and the mixed peptide material can be transported to the filling head through the discharge pipe, and then the external container can be filled.
[0012] Preferably, the top of the box has two feeding slots, and a PLC programmable controller is fixedly installed on the side of the box.
[0013] By adopting the above technical solution, the setting of the feeding chute facilitates material feeding, and the setting of the PLC programmable controller facilitates the control of the electrical parameters of the device.
[0014] Preferably, the bottom of the box is fixedly connected to four support legs, and the bottom end of each support leg is fixedly connected to a silicone block.
[0015] By adopting the above technical solution, the four support legs contact the ground through silicone blocks, absorbing the vibration of the motor during operation, improving stability, and avoiding component loosening or measurement deviation caused by vibration.
[0016] Preferably, a support plate is fixedly connected to the surface of each of the four support legs, and a collection box is attached to the top of each of the two sets of support plates.
[0017] By adopting the above technical solution, the support plate is stacked with a collection box to receive materials that may overflow during the filling process, keeping the working environment clean, reducing material waste, and facilitating subsequent cleaning.
[0018] Preferably, the bottom of the box is fixedly connected to two support seats, the discharge pipe is fixedly connected inside the support seats, and the inside of the box is coated with an anti-stick coating.
[0019] By adopting the above technical solution, the support base fixes the discharge pipe, reducing flow fluctuations caused by pipeline vibration. The anti-stick coating reduces the adhesion of the material surface, and the mixed material can be completely discharged without residue, avoiding cross-contamination of materials and reducing cleaning time.
[0020] Preferably, the box body is internally fixedly connected with four fixing blocks, and the sides of the four fixing blocks are overlapped with sealing plates. The interiors of the four fixing blocks and the sealing plates are each provided with four sets of threaded holes, and screws are threaded into the interiors of the four sets of threaded holes.
[0021] By adopting the above technical solution, the sealing plate is connected to the fixing block by screws, and the side wall of the box can be detached and opened to facilitate the inspection of the internal screws or the cleaning of residual materials.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] This spiral enema device for uniform mixing of peptides utilizes a spiral mixing mechanism. A drive motor rotates the shaft, and the primary screw, with its smaller diameter and pitch, rapidly propels the material downwards while simultaneously generating initial agitation. As the screw diameter and pitch gradually increase, the material is progressively compressed, increasing shear force and achieving fine mixing. The three-stage variable-diameter design subjectes the material to varying mechanical forces at different stages: the primary screw handles rapid conveying and fine mixing, the intermediate screw enhances shear dispersion, and the final screw, with its larger diameter and pitch, achieves uniform compression, preventing localized agglomeration. The mirror-polished stainless steel surface is smooth and free of dead corners, reducing material adhesion, preventing peptide residue and deterioration, and facilitating cleaning and disinfection.

Detailed Implementation
[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0032] Example 1: A spiral enema device for uniform mixing of polypeptides, referring to... Figure 1 , Figure 2 and Figure 3 The device includes a housing 1, a feeding mechanism 2, a spiral mixing mechanism 3, and a filling mechanism 4. The spiral mixing mechanism 3 includes a drive motor 301 fixedly mounted on the bottom of the housing 1 via a mounting bracket. Bearings 302 are fixedly connected to the top and bottom of the housing 1. A rotating shaft 303 is rotatably connected inside each of the two bearings 302. The bottom end of the rotating shaft 303 is fixedly connected to the output shaft of the drive motor 301. Several primary screws 304, intermediate screws 305, and final screws 306 are fixedly connected to the surface of the rotating shaft 303. The primary screws 304, intermediate screws 305, and final screws 306 are three-stage variable diameter screws.
[0033] The stirring core of the spiral mixing mechanism 3 consists of a three-stage variable-diameter screw. The diameter and pitch of the primary screw 304, intermediate screw 305, and final screw 306 decrease progressively. The primary screw 304, intermediate screw 305, and final screw 306 are all integrally forged from stainless steel and have a mirror-polished surface. By setting up the spiral mixing mechanism 3, the drive motor 301 can drive the rotating shaft 303 to rotate. The primary screw 304, with its smaller diameter and pitch, quickly pushes the material downwards, generating initial stirring. As the screw diameter and pitch gradually increase, the material is gradually compressed, the shear force is enhanced, and fine mixing is achieved. At the same time, the three-stage variable-diameter design ensures that the material is subjected to different intensities of mechanical action at different stages—the primary screw 304 is responsible for rapid conveying and fine mixing, the intermediate screw 305 strengthens shear dispersion, and the final screw 306 achieves uniform compression through its larger diameter and pitch, avoiding local agglomeration. The mirror-polished stainless steel surface is smooth and without dead corners, reducing material adhesion, preventing peptide residue and deterioration, and facilitating cleaning and disinfection.
[0034] Please see Figure 1 and Figure 4 The feeding mechanism 2 includes a metering belt scale 201 fixedly installed on the top of the housing 1. Two feed boxes 202 are fixedly connected to the top of the housing 1. A sealing cover 203 is movably connected to the top of the feed box 202 via a hinge. A handle 204 is fixedly connected to the top of the sealing cover 203. By setting up the feeding mechanism 2, the metering belt scale 201 can pre-weigh the raw materials according to the proportion, and then the data is observed by the PLC programmable controller 5, avoiding the error of manual feeding and ensuring the consistency of the mixing ratio. It is especially suitable for the standardized production of peptide formulations. The sealing cover 203 of the feed box 202 prevents material dust from escaping or external contamination. The handle 204 facilitates manual feeding, the hinge design supports quick opening and closing, and the sealing design prevents material evaporation or reaction with air, protecting operators from dust hazards. The filling mechanism 4 includes two metering pumps 401 fixedly installed at the bottom of the housing 1. The bottom end of the metering pump 401 is fixedly connected to the discharge pipe 402, and one end of the discharge pipe 402 is fixedly connected to the filling head 403. By setting the filling mechanism 4, the metering pump 401 can accurately control the output flow according to the instructions of the PLC programmable controller 5, and transport the mixed peptide material through the discharge pipe 402 to the filling head 403, and then perform enema operation on the external container.
[0035] Please see Figure 1The top of the housing 1 has two feeding slots 10. A PLC programmable controller 5 is fixedly installed on the side of the housing 1. The feeding slots 10 facilitate material feeding, and the PLC programmable controller 5 facilitates the control of the electrical parameters of the device. The bottom of the housing 1 is fixedly connected to four support legs 6. The bottom of the support legs 6 is fixedly connected to silicone blocks 7. The four support legs 6 are in contact with the ground through the silicone blocks 7, which absorbs the vibration of the motor during operation, improves stability, and avoids loosening of parts or measurement deviation caused by vibration.
[0036] Please see Figure 1 , Figure 4 and Figure 5 Each of the four support legs 6 has a support plate 8 fixedly connected to its surface. A collection box 9 overlaps the top of each of the two sets of support plates 8, allowing the support plates 8 to receive any overflowing material during filling, maintaining a clean working environment, reducing material waste, and facilitating subsequent cleaning. Two support seats 12 are fixedly connected to the bottom of the box body 1. A discharge pipe 402 is fixedly connected inside the support seats 12. The interior of the box body 1 is coated with an anti-stick coating 11. The support seats 12 fix the discharge pipe 402, reducing flow fluctuations caused by pipeline vibration. The anti-stick coating 11... The material surface adhesion is reduced, and the mixed material can be completely discharged without residue, avoiding cross-contamination of materials and reducing cleaning time. There are four fixed blocks 13 inside the box 1. The sides of the four fixed blocks 13 are overlapped with sealing plates 15. The interior of the four fixed blocks 13 and the interior of the sealing plates 15 are provided with four sets of threaded holes 14. The interior of the four sets of threaded holes 14 is threaded with screws 16. The sealing plates 15 are connected to the fixed blocks 13 by screws 16. The side wall of the box 1 can be disassembled and opened for easy inspection of the internal screws or cleaning of residual materials.
[0037] The implementation principle of this application embodiment is as follows: First, personnel can place the raw materials on the weighing belt scale 201. Then, the weighing data is synchronously transmitted to the PLC programmable controller 5. Personnel can monitor the feeding amount in real time to avoid random errors in manual feeding. After the ratio matching is completed, personnel will introduce the raw materials through the feeding box 202, and then enter the box 1 through the discharge chute 10. Finally, hold the handle 204 to close the sealing cover 203.
[0038] Then, the drive motor 301 operates, driving the rotating shaft 303 to rotate. Subsequently, the primary screw 304 with a smaller diameter and pitch quickly grabs the material and conveys it downward through the spiral thrust. At the same time, the shearing force of the screw blades is used for fine mixing, which is suitable for the initial dispersion of large particles. Then, the intermediate screw 305 with a larger diameter compresses the material and the pitch widens to increase the number of shearings per unit length, enhancing the friction and collision between materials and dispersing the aggregated polypeptide particles to the micron level. Finally, the final screw 306 with a larger diameter and pitch forms an extrusion chamber, where the raw material is repeatedly kneaded at the screw.
[0039] After mixing, the personnel put the external enema container onto the filling head 403, and then, through the operation of the metering pump 401, the material is fed into the container through the discharge pipe 402 and the filling head 403. The overflowing material falls into the collection box 9 for storage.
[0040] After a period of use, unscrew screw 16 to remove sealing plate 15, and finally clean the inside of box 1.
