Description

Technical Field

[0001] This invention relates to the field of emulsification equipment technology, specifically to an emulsification device based on a cold-melt gelatin powder compound thickener. Background Technology

[0002] Compound thickeners based on cold-soluble gelatin powder are often used as food additives. Under certain conditions, they can fully hydrate to form viscous, slippery, or gel-like macromolecular substances. In processed foods, they can increase the viscosity of the food or form gels, and have the functions of emulsification, stabilization, water retention, and crystallization control. They also help to improve the stability of food and extend its shelf life.

[0003] Currently, when preparing the aforementioned thickener using an emulsification device, various raw materials need to be added to an emulsification tank and then emulsified by stirring. During the stirring and mixing process in the emulsification tank, since all the raw materials have a certain viscosity, they tend to adhere to the inner wall of the emulsification tank. Furthermore, since the stirring structure in the emulsification device is mostly fixed, it is difficult to effectively remove these raw materials adhering to the inner wall of the emulsification tank and re-participate in the mixing process. This results in uneven material mixing and ultimately affects the overall emulsification effect and the consistency of product quality. Summary of the Invention

[0004] The purpose of this invention is to provide an emulsification apparatus based on a cold-melt gelatin powder compound thickener to solve the problems mentioned in the above process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An emulsification device based on a cold-melt gelatin powder compound thickener includes a tank and a top cover fixed to the top of the tank. A discharge pipe is fixedly installed through the bottom of the tank, and multiple feed pipes are fixedly installed through the top cover. An emulsification head assembly is rotatably mounted on the top cover, and a stirring frame is rotatably connected to the top cover. Two spiral conveying rods are rotatably connected to the stirring frame. Multiple spiral scrapers are fixedly installed on both sides of the stirring frame, and the outer sides of the spiral scrapers are in contact with the inner wall of the tank. The conveying directions of the spiral scrapers and the spiral conveying rods are opposite.

A water inlet pipe and a water outlet pipe are respectively fixed at the bottom and the top of one side of the insulated outer cylinder, and both the water inlet pipe and the water outlet pipe are connected to the interlayer.

[0010] As a preferred embodiment of the emulsification device based on cold-melt gelatin powder compound thickener described in this invention, a plurality of support columns are fixedly installed at the bottom of the tank.

[0011] As a preferred embodiment of the emulsification device based on cold-melt gelatin powder compound thickener described in this invention, a second toothed ring is fixedly installed inside the top cover, and a third gear is coaxially fixed to the top of each of the two spiral conveying rods, with both third gears meshing with the second toothed ring.

[0012] As a preferred embodiment of the emulsification device based on cold-melt gelatin powder compound thickener described in this invention, wherein: multiple fixed shafts are fixedly installed on the outside of the spiral conveying rod, and rotating plates for cleaning the bottom of adjacent spiral scrapers are rotatably connected to the outside of the multiple fixed shafts; torsion springs are sleeved on the outside of the multiple fixed shafts, and each torsion spring is fixedly connected at both ends to the corresponding fixed shaft and rotating plate.

[0013] As a preferred embodiment of the emulsification device based on cold-melt gelatin powder compound thickener described in this invention, the emulsification head assembly includes a fixed plate fixedly connected to the top cover and a rotating shaft rotatably connected to the fixed plate. Multiple fixed rods are fixedly installed at the bottom of the fixed plate, and a cylindrical stator is fixedly connected to the bottom of the multiple fixed rods. Multiple through slots are provided on the outside of the stator. A rotor is fixedly installed at the bottom of the rotating shaft, and the rotor is rotatably disposed inside the stator.

[0014] As a preferred embodiment of the emulsification device based on cold-melt gelatin powder compound thickener described in this invention, wherein: a first gear is rotatably connected to the fixed plate, and a first toothed ring is coaxially fixed to the top of the stirring frame, and the first gear meshes with the first toothed ring.

[0015] As a preferred embodiment of the emulsification device based on cold-melt gelatin powder compound thickener described in this invention, a second gear is coaxially fixed on the outer side of the rotating shaft, and the first gear and the second gear are meshed and connected.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention is equipped with a spiral scraper and a spiral conveying rod. When the mixing frame rotates, multiple spiral scrapers on both sides of the mixing frame scrape off the material adhering to the inner wall of the tank and convey the scraped material downward along the inner wall of the tank. At the same time, the rotating spiral conveying rod conveys the material at the bottom of the tank upward, thereby preventing the scraped material from accumulating at the bottom of the tank and allowing it to re-participate in the mixing, thus ensuring the full mixing of the material and improving the overall emulsification effect and quality consistency of the product.

[0018] 2. This invention uses a spiral scraper to push the material on the inner wall of the tank downwards and a spiral conveyor rod to transport the material at the bottom of the tank upwards, so that the material can circulate up and down in the tank. This avoids the material from stratifying during the mixing process in the tank and allows all the material to re-enter the emulsification head assembly for high-speed shear emulsification. This ensures the consistency of composition and viscosity of the material in the tank from top to bottom and improves the overall emulsification efficiency.

[0019] 3. As mentioned above, since the spiral conveyor is located inside the spiral scraper, the material in the tank can also circulate from the outside to the middle of the tank through the spiral scraper and the spiral conveyor. This allows the material in the middle of the tank to transfer the heat it carries to the low-temperature water in the jacket through the heat-conducting inner cylinder when it circulates to the inner wall of the tank. This effectively controls the temperature of the thickener during the emulsification process, thereby avoiding local high temperatures caused by stirring and friction, which could lead to changes in the properties or quality of some materials.

[0020] 4. When the spiral conveyor rod continuously conveys the material from the bottom upwards, the present invention can effectively prevent the scraped material from accumulating at the bottom of the tank.

[0021] 5. This invention incorporates a rotating plate, a fixed shaft, and a torsion spring. When the spiral conveyor rotates, it drives the fixed shaft to rotate around the axis of the spiral conveyor, which in turn drives the rotating plate to rotate around the axis of the spiral conveyor. When the rotating plate moves below the spiral scraper, it scrapes and cleans the material adhering to the bottom of the spiral scraper. When the relative position of the rotating plate and the bottom of the spiral scraper changes, the rotating plate rotates around the fixed shaft and rotates to stretch the torsion spring, preventing the rotating plate from affecting the rotation of the spiral conveyor. When the rotating plate is completely removed from under the spiral scraper, it resets through the torsion spring, facilitating the continued cleaning and scraping of the material adhering to the bottom of the spiral scraper in the next rotation. This reduces the pushing resistance of the spiral scraper while minimizing material waste.

[0022] 6. This invention drives the second gear to rotate through the rotation of the shaft. The meshing transmission between the second gear, the first gear, and the first gear ring causes the first gear ring to drive the stirring frame to rotate. Since the number of teeth on the first gear ring is much larger than that on the second gear, they form a reduction mechanism. This allows the stirring frame to rotate smoothly at a low speed when the shaft rotates at high speed. When the stirring frame rotates, it drives the two spiral conveying rods to revolve. Through the internal meshing of the third gear and the fixed second gear ring, the spiral conveying rods rotate on their own axis. Thus, by using only one motor to drive the shaft to rotate, the high-speed emulsification and low-speed stirring processes of the equipment can be achieved simultaneously, reducing the equipment manufacturing cost.

[0035] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention. The invention is by no means limited to any specific configurations and algorithms presented below, but covers any modifications, substitutions, and improvements to elements, components, and algorithms without departing from the spirit of the invention. Well-known structures and techniques are not shown in the drawings and the following description in order to avoid unnecessarily obscuring the invention.

[0036] Example 1, referring to Figure 1-11 This is the first embodiment of the present invention, which provides an emulsification device based on a cold-soluble gelatin powder compound thickener. The emulsification device based on the cold-soluble gelatin powder compound thickener includes a tank body 1 and a top cover 2 fixed to the top of the tank body 1. A discharge pipe 4 is fixedly fixed through the bottom of the tank body 1. Multiple feed pipes 3 are fixedly fixed through the top cover 2. An emulsification head assembly is rotatably provided on the top cover 2. A stirring frame 23 is rotatably connected to the top cover 2. Two spiral conveying rods 24 are rotatably connected to the stirring frame 23. Multiple spiral scrapers 26 are fixedly installed on both sides of the stirring frame 23, and the outer sides of the multiple spiral scrapers 26 are in contact with the inner wall of the tank body 1. The conveying directions of the spiral scrapers 26 and the spiral conveying rods 24 are opposite.

[0037] The two sets of spiral scrapers 26 on both sides of the stirring frame 23 are staggered in the vertical direction.

[0038] Two arc-shaped rods 231 are fixedly installed at the bottom of the stirring frame 23, and the outer side of the arc-shaped rods 231 abuts against the inner bottom surface of the tank 1.

[0039] Multiple support columns 11 are fixedly installed at the bottom of the tank body 1.

[0040] During use, the gelatin-based compound thickener is usually in powder form. Multiple feed pipes 3 on the top cover 2 are used to add different raw materials. First, water is added into the tank 1 as a solvent through one of the feed pipes 3. Then, the stirring frame 23 is driven to rotate, so that the solvent in the tank 1 forms a vortex. Then, the gelatin-based compound thickener is slowly added through another feed pipe 3, so that the thickener powder enters the vortex in a dispersed manner, thereby avoiding the thickener powder from clumping. Then, the stirring frame 23 is used to stir and mix the materials, and at the same time, the emulsification head assembly is used to perform high-speed shear emulsification of the materials.

[0041] When the materials are stirred and mixed in tank 1, due to the viscosity of each raw material and the viscosity of the resulting solution, the materials adhere to the inner wall of tank 1 and cannot participate in the stirring and emulsification process, resulting in uneven mixing and ultimately affecting the overall emulsification effect and product quality consistency. At this time, the two sets of spiral scrapers 26 on the outer side of the rotating stirring frame 23 rotate with the stirring frame 23 inside tank 1. Simultaneously, the two spiral conveying rods 24 rotate with the stirring frame 23 and also rotate on their own axis around the stirring frame 23. The two sets of spiral scrapers 26 on both sides of the stirring frame 23 scrape off the material adhering to the inner wall of tank 1. The spiral structure of the spiral scraper 26 simultaneously conveys the scraped material downwards along the inner wall of the tank 1. The two sets of spiral scrapers 26 on both sides of the mixing frame 23 are staggered in the vertical direction, so that the material adhering to the inner wall of the tank 1 can be conveyed downwards. When the scraped material moves to the bottom of the tank 1, the rotating spiral conveying rod 24 causes the material at the bottom of the tank 1 to be conveyed upwards along the spiral conveying rod 24, thereby preventing the material scraped by the spiral scraper 26 from accumulating at the bottom of the tank 1, so that the scraped material can rise and re-participate in the mixing, thereby ensuring the full mixing of the material and further improving the overall emulsification effect and quality consistency of the product.

[0042] The spiral conveyor 24 conveys the material at the bottom of the tank 1 upwards, while the spiral scraper 26 conveys the material downwards, enabling continuous vertical circulation of the material within the tank 1. This allows for the redistribution of the material in the vertical direction, preventing stratification during mixing. Furthermore, the upward conveying by the spiral conveyor 24 brings the material at the bottom of the tank 1 closer to the inlet of the emulsifying head assembly, ensuring that all material has the opportunity to re-enter the emulsifying head assembly for high-speed shear emulsification. This guarantees the consistency of composition and viscosity of the material within the tank 1 from top to bottom and improves the overall emulsification efficiency of the emulsification device.

[0043] In addition, as the screw conveyor 24 continuously conveys the material at the bottom of the tank 1 upwards, it can effectively prevent the scraped material from accumulating at the bottom of the tank 1.

[0044] In addition, after the stirring and emulsification are completed, when the mixed solution is discharged, the bottom discharge pipe 4 is opened and the solution is discharged from the discharge pipe 4. At the same time, the stirring frame 23 continues to rotate, so that the spiral scraper 26 scrapes off the solution adhering to the inner wall of the tank 1 and conveys it downward. When the solution moves to the bottom of the tank 1, the rotating stirring frame 23 drives the arc rod 231 to rotate, so that the arc rod 231 pushes the material at the bottom of the tank 1 to move it gradually towards the end of the discharge pipe 4 and finally discharges it from the discharge pipe 4, thereby reducing the waste of the solution after stirring and emulsification.

[0045] Preferably, the top cover 2 can be used to seal the tank 1. After all materials have been added, the top cover 2 can be used to seal the tank 1 to evacuate the air inside the tank 1, so that a certain degree of vacuum is generated inside the tank 1. Then, stirring and emulsification can continue, which can avoid the presence of too many air bubbles in the emulsified solution.

[0046] Preferably, the tank body 1 includes an insulated outer cylinder and a heat-conducting inner cylinder, and a jacket 14 disposed between the insulated outer cylinder and the heat-conducting inner cylinder. A water inlet pipe 13 and a water outlet pipe 12 are fixed to the bottom and one side top of the insulated outer cylinder, respectively. Both the water inlet pipe 13 and the water outlet pipe 12 are connected to the jacket 14.

[0047] Therefore, during the stirring and emulsification process, the solution must be kept at a suitable low temperature to avoid flavor loss or quality changes caused by high temperatures. Low-temperature water is introduced through the inlet pipe 13 at the bottom of the insulated outer cylinder of tank 1. As the liquid level rises in the interlayer 14 between the insulated outer cylinder and the heat-conducting inner cylinder, the water eventually flows out through the outlet pipe 12, thus achieving circulation of the low-temperature water within the interlayer 14. The low-temperature water exchanges heat with the material inside tank 1 through the heat-conducting inner cylinder, ensuring that the inside of tank 1 remains within a suitable temperature range for the emulsification process. Furthermore, the spiral conveyor 24 transports the material upwards from the bottom of tank 1, while the spiral scraper 26 transports the material downwards, enabling continuous vertical circulation of the material within tank 1. Meanwhile, since the spiral conveyor rod 24 is located inside the spiral scraper 26, the material simultaneously circulates from the inner wall of the tank 1 to the middle of the tank 1. In this way, the material at the inner wall of the tank transfers heat to the low-temperature water through the heat-conducting inner cylinder. Through the circulation from the inner wall of the tank 1 to the middle of the tank 1, the heat generated by the material in the middle of the tank 1 under the action of stirring and high-speed shearing of the emulsification head assembly can be quickly transferred to the low-temperature water in the jacket 14. And through the circulation of the low-temperature water, the heat is conducted to the outside of the tank 1. In this way, the heat conduction efficiency is improved by the circulation of the material, which can effectively control the temperature of the thickener during the emulsification process, thereby avoiding local high temperature caused by stirring friction and high-speed shearing, which would lead to changes in the properties or quality of some materials.

[0048] Example 2, refer to Figure 2-11 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0049] The emulsifying head assembly includes a fixing plate 21 fixedly connected to the top cover 2 and a rotating shaft 22 rotatably connected to the fixing plate 21. Multiple fixing rods 211 are fixedly installed at the bottom of the fixing plate 21. A cylindrical stator 212 is fixedly connected to the bottom of the multiple fixing rods 211. Multiple through slots 213 are provided on the outside of the stator 212. A rotor 221 is fixedly installed at the bottom of the rotating shaft 22. The rotor 221 is rotatably disposed within the stator 212.

[0050] A first gear 214 is rotatably connected to the fixed plate 21, and a first gear ring 232 is coaxially fixed to the top of the stirring frame 23. The first gear 214 meshes with the first gear ring 232.

[0051] A second gear 222 is coaxially fixed on the outer side of the rotating shaft 22, and the first gear 214 is meshed with the second gear 222.

[0052] A second toothed ring 242 is fixedly installed inside the top cover 2. A third gear 241 is coaxially fixed to the top of each of the two spiral conveying rods 24. Both third gears 241 mesh with the second toothed ring 242.

[0053] During use, a motor is fixedly installed on the top cover 2. The output shaft of the motor is fixedly connected to the rotating shaft 22. When the motor drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the rotor 221 to rotate. The fixing plate 21 is fixed to the top cover 2, and then the stator 212 is fixed relative to the top cover 2 by multiple fixing rods 211. Multiple through slots 213 are provided on the outside of the stator 212. The rotor 221 rotates at high speed under the action of the rotating shaft 22, causing the material between the blades of the rotor 221 to be thrown out at high speed. Through the narrow gap between the stator 212 and the rotor 221, the material is subjected to strong hydraulic shear in the narrow gap between the stator 212 and the rotor 221, and the interface is broken. The centrifugal force generated by the high speed of the material causes the liquid layer to collide and tear violently with the stator 212, further refining the droplets, thereby achieving the effect of emulsification. After the material between the blades of the rotor 221 is centrifugally thrown out, a negative pressure is formed inside the rotor 221, causing the material to be continuously drawn into the rotor 221, thereby achieving a continuous emulsification process.

[0054] The emulsifying head assembly adopts a structure that allows feeding from both the top and bottom. The stator 212 has a feeding hole at the top and an open structure at the bottom. The rotor 221 has a fixed baffle in the middle, which abuts against the inner wall of the stator 212. When the rotor 221 rotates, the material between the blades of the rotor 221 is blocked by the fixed baffle and can only be thrown radially by centrifugal force. This causes the material to collide and tear violently with the stator 212, further refining the droplets, and finally passing through the through groove 213 on the stator 212 and leaving the emulsifying head assembly. The fixed baffle prevents the material from directly passing through the rotor 221 along the axis of the rotor 221, ensuring the radial movement of the material.

[0055] In addition, when the rotating shaft 22 drives the second gear 222 to rotate, the second gear 222 meshes with the first gear 214, causing the first gear 214 to rotate on the fixed plate 21. The first gear 214 also meshes with the first gear ring 232. Through meshing, the first gear ring 232 drives the stirring frame 23 to rotate. Since the number of teeth of the first gear ring 232 is much larger than that of the second gear 222, the second gear 222, the first gear 214 and the first gear ring 232 form a speed reduction mechanism. This allows the rotating shaft 22 to drive the rotor 221 to rotate at high speed while the stirring frame 23 can rotate at low speed and smoothly, ensuring the smooth operation of the mixing process and avoiding unnecessary vibration of the equipment.

[0056] Meanwhile, as the mixing frame 23 rotates, it drives the two spiral conveying rods 24 to revolve around the axis of the mixing frame 23. The third gear 241 at the top of the two spiral conveying rods 24 meshes with the second gear ring 242 fixed on the top cover 2, causing the two third gears 241 to roll in the second gear ring 242 respectively. This causes the two third gears 241 to drive the two spiral conveying rods 24 to rotate around their own axes. This achieves the simultaneous revolution of the two spiral conveying rods 24 around the mixing frame 23 and rotation of their own axes. As a result, the equipment can simultaneously achieve high-speed emulsification and low-speed mixing processes by driving the rotating shaft 22 with only one motor, effectively reducing the equipment manufacturing cost.

[0057] The remaining structure is the same as that in Example 1.

[0058] Example 3, referring to Figure 2-9 This is the third embodiment of the present invention, which differs from the second embodiment in that:

[0059] Multiple fixed shafts 251 are fixedly installed on the outside of the spiral conveyor rod 24. Rotary plates 25 for cleaning the bottom of adjacent spiral scrapers 26 are rotatably connected to the outside of the multiple fixed shafts 251. Torsion springs 252 are sleeved on the outside of the multiple fixed shafts 251. Each torsion spring 252 is fixedly connected to the corresponding fixed shaft 251 and the rotating plate 25 at both ends.

[0060] During use, the spiral conveyor rods 24 are rotatably connected to the mixing frame 23, so that the two spiral conveyor rods 24 are located inside the two sets of spiral scrapers 26 respectively. Multiple fixed shafts 251 fixedly installed on the outer sides of the two spiral conveyor rods 24 correspond to multiple spiral scrapers 26 respectively. When the spiral conveyor rods 24 rotate around their own axis, the fixed shafts 251 on the outer sides of the spiral conveyor rods 24 move to below the corresponding spiral scraper 26, thereby causing the rotating plate 25 to move to below the corresponding spiral scraper 26. The top of the rotating plate 25 abuts against the bottom of the spiral scraper 26. During the continuous rotation of the spiral conveyor rods 24, the fixed shafts 251 pass under the corresponding spiral scraper 26, and the top of the rotating plate 25 scrapes off some of the material adhering to the bottom of the spiral scraper 26. When the relative position changes, the height of the top of the rotating plate 25 relative to the fixed shaft 251 decreases. At this time, the spiral scraper 26 pushes the rotating plate 25 to rotate around the fixed shaft 251. At the same time, the rotating plate 25 and the fixed shaft 251 rotate and stretch the torsion spring 252. When the top of the rotating plate 25 is completely moved out of the spiral scraper 26, the rotating plate 25 is reset by the elastic force of the torsion spring 252. This makes it easier for the fixed shaft 251 and the rotating plate 25 to continue cleaning and scraping the material adhering to the bottom of the spiral scraper 26 when rotating the next revolution. The cleaning and scraping of the bottom of the spiral scraper 26 by the rotating plate 25 can reduce the pushing resistance of the spiral scraper 26 to push the material downward, making it easier to clean the inner wall of the tank 1. On the other hand, when the solution is discharged after stirring and emulsification, the rotating plate 25 can clean the part of the solution adhering to the spiral scraper 26 to reduce waste.

[0061] Furthermore, when the spiral conveyor 24 rotates, it drives the fixed shaft 251 to rotate around the axis of the spiral conveyor 24. When the fixed shaft 251 is away from the spiral scraper 26, the rotating plate 25 on the fixed shaft 251 will push the material scraped from the bottom of the spiral scraper 26 to the middle of the tank 1. This pushes the scraped material to the upper and lower sides of the stator 212 and rotor 221 of the emulsification head assembly. This facilitates the formation of negative pressure in the rotor 221, allowing the scraped material to be directly sucked into the gap between the rotor blades, thereby accelerating the emulsification process and improving the emulsification effect.

[0062] The remaining structure is the same as that in Example 2.
