A high-efficiency dispersing and mixing machine for food slurry

Abstract

This utility model discloses a high-efficiency dispersion mixer for food slurry. A three-bladed paddle is fixedly installed on a dispersion shaft to disperse materials in a material tank. Two spiral ribbons are symmetrically arranged on opposite sides of the frame, and scraper plates are hinged to both the long and short sides of the frame. The ends of the scraper plates contact the inner wall of the material tank. The spiral ribbons are helical, with each ribbon extending diagonally from one corner of the frame from top to bottom. By setting up a composite structure of a three-bladed paddle, a rectangular frame, and spiral ribbons, multi-dimensional shearing and cyclic mixing are achieved. The three-bladed paddle provides high-intensity shearing force, effectively dispersing solid particles; the rectangular frame drives the spiral ribbons on both sides to rotate in opposite directions, forming a "sandwich" mixing chamber (upper layer convection → middle layer shearing → lower layer reflux), promoting the material to tumble up and down without dead corners; the hinged scraper plates dynamically adhere to the inner wall, thoroughly removing adhering materials, avoiding stratification and clumping, and significantly improving the mixing uniformity and fineness of high-viscosity slurries.

Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to a high-efficiency dispersion and mixing machine for food slurry. Background Technology

[0002] In the food processing industry, the homogenization of high-viscosity slurries such as sauces, dairy products, and condiments is a crucial step affecting product quality. These slurries typically contain solid particles such as colloids and flavorings, and are characterized by high viscosity and poor flowability. However, traditional mixing equipment has significant technical shortcomings in actual production:

[0003] 1. Insufficient Mixing Uniformity: Traditional mixers have limited mixing capacity for high-viscosity slurries, making it easy for materials to separate and clump. Due to the lack of an efficient overall circulation mechanism, materials in different areas of the mixer cannot achieve sufficient exchange, resulting in uneven component distribution and seriously affecting the consistency of product texture and flavor.

[0004] II. Low Shear Dispersion Efficiency: Traditional equipment provides insufficient shear force for dispersing solid particles (such as fragrances and colloids). Particles are difficult to break down and wet sufficiently, easily forming agglomerates or undissolved particles in the slurry, which not only reduces dispersion but may also cause product stability issues.

[0005] III. Functional Limitations Constrain Process Implementation: Existing equipment generally suffers from functional limitations—it may only possess high-speed dispersion capabilities but cannot achieve gentle mixing; it may only support low-speed stirring and lack high shear force; it may lack an integrated wall scraping mechanism, causing material to adhere to the cylinder wall and create dead zones; or it may lack a sealed vacuum environment, limiting its degassing and handling capabilities for hygiene-sensitive materials. This fragmented functionality makes it difficult for enterprises to match the ever-changing process requirements in new material research and development and the production of complex formulations, severely restricting technological innovation and production efficiency improvements.

[0006] Therefore, there is an urgent need for a composite device that integrates efficient dispersion, strong shearing, global mixing, adaptive wall scraping, and closed-loop processing capabilities to meet the stringent requirements for high uniformity, residue-free processing, and process adaptability in the homogenization of food slurries. It is evident that existing technologies still require improvement and enhancement. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a high-efficiency food slurry dispersion mixer to solve one or more problems existing in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency food slurry dispersion mixer, comprising a dispersion mechanism for dispersing materials in a material cylinder, the dispersion mechanism comprising: a dispersion shaft, rotatably mounted on the machine body and extending into the material cylinder for transmitting rotational torque; a three-bladed paddle, fixedly mounted on the dispersion shaft for dispersing materials in the material cylinder; a frame, having a rectangular structure, rotatably mounted on the machine body, with two spiral ribbons symmetrically arranged on opposite sides of the frame, and scraper plates hinged to both the long and short sides of the frame; scraper plates, with their ends contacting the inner wall of the material cylinder for scraping off materials adhering to the inner wall of the material cylinder; and spiral ribbons, each spiral ribbon extending from one corner of the frame diagonally downwards.

[0009] In one embodiment of the present invention, a base and a hydraulic cylinder vertically disposed on the base are further included. The machine body is fixedly connected to the end of the piston rod of the hydraulic cylinder for driving the overall lifting and lowering of the machine body by the hydraulic cylinder.

[0010] In one embodiment of this utility model, a geared motor is provided on the machine body, and the geared motor is connected to the inner bearing in sequence through a chain and a sprocket. The frame is fixedly installed on the inner bearing.

[0011] In one embodiment of the present invention, an outer bearing is also included, which is fitted onto the outside of the inner bearing and fixed to the machine body.

[0012] In one embodiment of the present invention, the dispersion shaft is coaxially disposed inside the inner bearing.

[0013] In one embodiment of the present invention, the base is provided with a tank placement rack and a locator, the tank placement rack carries a material cylinder, and the cylinder body of the material cylinder holds a locator for fixing the position.

[0014] In one embodiment of the present invention, a hydraulic station connected to the oil cylinder to provide oil pressure is also included, wherein the hydraulic station and the cylinder mounting bracket are respectively disposed at opposite ends of the base.

[0015] In one embodiment of the present invention, the positioner is provided with an insertion hole, and a locking block is provided on the outer wall of the material cylinder; it also includes a pin, which can be inserted into the insertion hole and cooperate with the locking block to form a locking structure.

[0016] In one embodiment of the present invention, the bottom of the base is rotatably equipped with casters, and a push handle is inclinedly provided on the base.

[0017] In one embodiment of this utility model, a dispersing motor is provided on the machine body, and the dispersing motor is connected to the dispersing shaft in sequence through a V-belt and a pulley.

[0018] As described above, the high-efficiency dispersion mixer for food slurries of this invention has the following beneficial effects: The high-speed rotation of the three-bladed paddle driven by the dispersion shaft generates strong shear force, instantly breaking up solid particle agglomerates and significantly improving the dispersion efficiency of sparingly soluble substances such as flavorings and colloids. Simultaneously, the rectangular frame drives the double spiral ribbons to rotate in both directions, creating a three-dimensional material flow through the diagonally spiral structure of the ribbons from top to bottom. Combined with the adaptive movement of the hinged scraper against the cylinder wall, this completely eliminates mixing dead zones and wall residue. The strong shear zone of the three-bladed paddle, the forced convection zone driven by the spiral ribbons, and the bottom reflux zone form a "sandwich-style mixing chamber," achieving stratified circulation of materials within the cylinder: the upper layer forms strong convection to promote overall exchange, the middle layer uses high shear to pulverize particles and improve fineness, and the lower layer uses the spiral ribbon to drive the material upwards, forming a closed reflux. This multi-mechanism synergistic effect effectively solves the problem of stratification and agglomeration in high-viscosity slurries, enabling food slurries such as sauces and dairy products to achieve molecular-level homogenization in a closed environment, while also considering vacuum process adaptability, providing integrated technical support for complex formula development and efficient production.

Detailed Implementation

[0026] This utility model provides a high-efficiency dispersion and mixing machine for food slurry. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Please see Figures 1 to 4 This utility model provides a high-efficiency food slurry dispersion mixer, including a dispersion mechanism for dispersing materials in a material cylinder 2. The dispersion mechanism includes: a dispersion shaft 3, rotatably mounted on a machine body 1 and extending into the material cylinder 2 to transmit rotational torque; a three-bladed paddle 4, fixedly mounted on the dispersion shaft 3 for dispersing materials in the material cylinder 2; a frame 5, rectangular in structure, rotatably mounted on the machine body 1, with two spiral ribbons 7 symmetrically arranged on opposite sides of the frame 5, and scraper plates 6 hinged to both the long and short sides of the frame 5; the scraper plates 6 have ends that contact the inner wall of the material cylinder 2 for scraping off materials adhering to the inner wall of the material cylinder 2; and spiral ribbons 7, each spiral ribbon 7 extending from one corner of the frame 5 diagonally downwards. The high-speed rotation of the three-bladed paddle 4 generates strong shear force, instantly pulverizing solid particles such as colloids and spices, significantly improving dispersion fineness; the rectangular frame 5 and double spiral ribbons 7 form a two-way three-dimensional logistics system, pushing the material up and down to eliminate stratification and agglomeration; the hinged scraper 6 adaptively conforms to the cylinder wall, thoroughly removing residues, avoiding dead corners, and ensuring the uniformity of mixing high-viscosity slurries (such as sauces). This achieves "sandwich mixing": forced convection in the upper layer, high shear in the middle layer, and closed reflux in the lower layer, achieving molecular-level homogenization.

[0028] In detail, two three-bladed paddles 4 are fixedly installed on the dispersion shaft 3. The two paddles 4 are arranged in a row and mounted opposite each other on the dispersion shaft 3. As the dispersion shaft 3 rotates, the blades of the upper and lower three-bladed paddles 4 advance at opposite helical angles, forming a counter-shearing effect. The upper three-bladed paddle 4 uses its 45° inclined blades to press the material downwards and initially break up agglomerated particles, while the lower three-bladed paddle 4 uses a reverse helical angle to flip the material upwards, forming a vortex convection with the material falling from above. This positive and negative assembly structure allows the material to form a 'compression-return' circulation path in the axial direction, and generates multi-dimensional shear force in the radial direction through the staggered blades. This effectively breaks the laminar flow state of high-viscosity slurry, while preventing the sidewall material cleaned by the screw ribbon 7 and scraper plate 6 from directly settling. This ensures that the material in the entire cylinder continuously renews the mixing interface, significantly improves the dispersion uniformity of solid particles (such as fragrances and colloids), and avoids the material retention problem in the low-pressure zone of the axis caused by traditional single-rotation paddles.

[0029] It also includes a base 8 and a hydraulic cylinder 9 vertically mounted on the base 8. The machine body 1 is fixedly connected to the end of the piston rod of the hydraulic cylinder 9, and is used to drive the overall lifting and lowering of the machine body 1 by the hydraulic cylinder 9. The hydraulic cylinder 9 drives the overall lifting and lowering of the machine body 1, which can flexibly adjust the distance between the machine body 1 and the material cylinder 2, adapting to material cylinders 2 of different heights, making operation convenient and highly stable. The lifting design facilitates the quick loading and unloading of the material cylinder 2, while avoiding the problem of uneven mixing caused by height mismatch in traditional fixed equipment, thus improving the versatility of the equipment.

[0030] A geared motor 10 is mounted on the machine body 1. The geared motor 10 is connected to the inner bearing 13 via a chain 11 and a sprocket 12. The frame 5 is fixedly mounted on the inner bearing 13. The geared motor 10 drives the inner bearing 13 through the chain 11 and sprocket 12, ensuring smooth and reliable power transmission, reducing vibration and noise, and extending the equipment's lifespan. The frame 5 is fixed to the inner bearing 13 to ensure its rotational stability and prevent a decrease in mixing efficiency due to shaking, making it particularly suitable for long-term uniform mixing of high-viscosity materials.

[0031] It also includes an outer bearing 14, which is fitted outside the inner bearing 13 and fixed to the machine body 1. The outer bearing 14, fitted outside the inner bearing 13, forms a double-layer support structure, enhancing the stability and load-bearing capacity of the frame 5 during rotation. This design can effectively disperse radial force, reduce wear on the inner bearing 13, improve equipment durability, and adapt to the needs of high-frequency, high-load continuous production. The dispersion shaft 3 is coaxially inserted inside the inner bearing 13. The coaxial insertion of the dispersion shaft 3 inside the inner bearing 13 shortens the transmission path, reduces axial offset and vibration, and ensures that the shearing force of the three-bladed paddle 4 is accurately applied to the material. The coaxial design can also reduce energy consumption and improve power transmission efficiency, especially suitable for the fine dispersion of high-viscosity slurries; in addition, it enables the independent movement of the three-bladed paddle 4 (high speed) and the frame 5 (low speed), without interference and with a compact structure.

[0032] The base 8 is equipped with a tank placement rack 15 and a positioner 16. The tank placement rack 15 supports the material cylinder 2, and the positioner 16, used for fixing the position, is held abutted against the cylinder body of the material cylinder 2. The tank placement rack 15 and the positioner 16 work together to ensure that the material cylinder 2 is firmly fixed, avoiding leakage or tilting caused by shaking during the mixing process. The positioner 16 simplifies the installation and positioning process of the material cylinder 2, improves operational efficiency, and ensures the safety and consistency of the mixing process. To further improve the stability of the material cylinder 2, the positioner 16 is provided with an insertion hole, and a locking block is provided on the outer wall of the material cylinder 2; it also includes a pin 18, which can be inserted into the insertion hole and cooperate with the locking block to form a locking structure. The cooperation between the pin 18 and the locking block forms a double locking structure to prevent the material cylinder 2 from accidentally shifting or falling off during the mixing process. The insertion hole design facilitates quick insertion and removal, is easy to operate, and has high locking reliability, significantly improving production safety and avoiding equipment damage or material waste caused by cylinder displacement.

[0033] In this embodiment, the opening of the material cylinder 2 is provided with an opening and closing cover. The cover has a through hole for the dispersing shaft 3 to pass through, which ensures the sealing of the material cylinder 2. Specifically, the inner wall of the through hole of the cover has an annular sealing groove, in which a high-temperature resistant fluororubber sealing ring is embedded, forming a dynamic sealing fit with the dispersing shaft 3. The edge of the cover fits tightly with the opening of the material cylinder 2, ensuring that the material will not leak out during the mixing process. To further improve the sealing performance, in another feasible embodiment, the diameter of the through hole and the dispersing shaft 3 are interference-fitted, and food-grade lubricating silicone grease is applied to the contact surface to further reduce rotational friction and enhance sealing reliability. This design not only meets the dynamic sealing requirements when the dispersing shaft 3 rotates at high speed, but also effectively prevents outside air from entering the cylinder, avoiding material oxidation or contamination. It is particularly suitable for the aseptic production environment of high-viscosity food slurries such as sauces and dairy products.

[0034] It also includes a hydraulic station 17 connected to the cylinder 9 to provide oil pressure. The hydraulic station 17 and the cylinder mounting bracket are respectively located at opposite ends of the base 8. The hydraulic station 17 and the tank mounting bracket 15 are located at opposite ends of the base 8 to balance the center of gravity of the equipment and improve overall stability. The hydraulic station 17 is independently pressurized to ensure that the lifting and lowering movements of the cylinder 9 are smooth and controllable, avoiding vibration of the machine body 1 caused by oil pressure fluctuations, and further ensuring mixing accuracy.

[0035] The base 8 is rotatably equipped with casters 19 at its bottom, and a push handle 20 is inclinedly mounted on the base 8. The design of the casters 19 and the inclined push handle 20 at the bottom of the base 8 gives the equipment flexible mobility, making it easy to move between different production areas. The push handle 20 is ergonomic, reducing the labor intensity of the operator, and is especially suitable for workshop environments where frequent workstation changes are required.

[0036] A dispersing motor 21 is installed on the machine body 1. The dispersing motor 21 is connected to the dispersing shaft 3 via a V-belt 22 and a pulley 23. The dispersing motor 21 drives the dispersing shaft 3 through the V-belt 22 and pulley 23, which can achieve stepless speed regulation to adapt to the speed adjustment of different material viscosities and process requirements. The V-belt 22 has a buffering and shock absorption function, which reduces the impact on the motor load and can also prevent high-viscosity materials from jamming and causing the motor to burn out, thus extending the life of the motor and transmission components and reducing energy consumption.

[0037] In summary, this utility model of a high-efficiency food slurry dispersion mixer achieves efficient homogenization of food slurry through an innovatively designed dispersion mechanism. Specifically, the three-bladed impeller 4 and the rotating spiral ribbon 7 frame 5 work together to form a unique "sandwich-style mixing chamber" structure: the upper layer of material experiences strong convection under the high-speed shearing of the three-bladed impeller 4; the middle layer fully disperses solid particles through the multi-directional shearing force generated by the rotating frame 5; and the lower layer of spiral ribbon 7 pushes the material back in a spiral flow, forming a seamless, tumbling circulation. Simultaneously, the hinged scraper plates 6 on the long and short sides of the rectangular frame 5 dynamically adhere to the inner wall of the material cylinder 2, thoroughly removing adhering material and preventing stratification and clumping. This design significantly improves the mixing uniformity and solid particle dispersion of high-viscosity slurries through the coupling effect of multi-dimensional shearing, convection, and reflux. It is particularly effective for food slurries containing flavorings or colloids, such as sauces and dairy products, by refining particle size, enhancing emulsification stability, and greatly improving product smoothness and consistency of taste. This overcomes the problems of uneven mixing and poor process adaptability caused by insufficient shearing force and limited functionality in traditional equipment. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.
