[0002] Colorants, also known as food pigments, are substances used primarily for coloring food, giving it color and improving its appearance. Currently, there are more than 60 commonly used food colorants in the world, and 46 are permitted for use in my country. They are classified into two categories according to their source and properties: synthetic food colorants and natural food colorants. Different ratios of compound ingredients can produce different types of compound additives.

[0003] Emulsification is required during the preparation of compound colorants. However, commonly used emulsification equipment does not adequately disperse high-viscosity materials during the preparation of compound colorants, which can easily lead to colorant agglomeration. At the same time, the materials tend to adhere to the inner wall of the equipment, and the residue can cause cross-contamination. Summary of the Invention

[0027] Referring to Figures 1-5, an emulsification device for preparing compound colorants includes a base plate 1 and a rotating seat 2 rotatably mounted on the base plate 1. The rotating seat 2 is mounted on the base plate 1 via a thrust bearing. An emulsification tank 3 with an open top is coaxially arranged on the rotating seat 2 and placed on the rotating seat 2. The bottom of the emulsification tank 3 is provided with a discharge pipe 4 with a discharge valve. The middle of the rotating seat 2 is provided with an opening 5 for the discharge pipe 4 to pass through, so that the discharge pipe 4 can be connected to other pipes or receiving equipment. A control console 6 is fixedly arranged on the base plate 1 on one side of the emulsification tank 3. A top plate 7 is movably arranged above the control console 6. A sealing cover 8 facing the opening of the emulsification tank 3 is arranged on the lower surface of the top plate 7. An emulsification mechanism is arranged on the top plate 7 on the inner circumference of the sealing cover 8. A lifting mechanism is arranged inside the control console 6. The lifting mechanism is used to drive the top plate 7 to vertically lift the sealing cover 8 and the emulsification mechanism so that the sealing cover 8 covers the top of the emulsification tank 3 and the emulsification mechanism acts on the material inside the emulsification tank 3.

[0028] The emulsification mechanism includes an outer bushing 9 fixedly connected to the top plate 7. A connector 10 is integrally formed at the bottom of the outer bushing 9. A stator ring 11 is fixedly connected to the bottom of the connector 10 by bolts and a hanger rod. A plurality of external shearing slots 12 are evenly opened on the outer circumferential surface of the stator ring 11 (23 in this embodiment). An inner rotating rod 91 is coaxially rotatably arranged in the middle of the outer bushing 9. The bottom of the inner rotating rod 91 extends downward into the stator ring 11 and is fixedly connected to a rotor ring 13. A plurality of internal shearing slots 14 are coaxially arranged on the outer circumferential surface of the rotor ring 13 (19 in this embodiment). A shearing gap for the material is formed between the external shearing slots 12 and the internal shearing slots 14. The rotor ring 13 is coaxially arranged with the stator ring 11. A composite shearing structure combining the stator ring 11 and the rotor ring 13 is adopted. When the rotor ring 13 rotates at 2800 rpm, a local shearing rate ≥8500 s can be generated. -1 Compared to traditional paddle-type emulsifiers (≤2200s with the same power consumption), -1 It increases the homogenization of colorants by 3.8 times, effectively improving the homogenization of colorants and avoiding particle agglomeration.

[0029] The outer bushing 9 is provided with at least one scraper 15 for cooperating with the inner circumferential surface of the emulsifying tank 3. A drive mechanism for driving the rotating seat 2 to rotate the emulsifying tank 3 is provided on the bottom plate 1. A power device for driving the inner rotating rod 91 to rotate the rotor ring 13 is provided on the top plate 7.

[0030] Specifically, the outer shear opening 12 is a parallelogram structure inclined relative to the axis of the stator ring 11, and the inner shear opening 14 is a rectangular structure parallel to the axis of the rotor ring 13; the inner rotating rod 91 is fixedly connected to the stator ring 11 by a stirring blade. The stirring blade 92 can prevent water from accumulating inside the stator ring 11, effectively improving the emulsification effect.

[0031] Specifically, the lifting mechanism consists of two synchronously operating lifting cylinders 16, with the power output end of each lifting cylinder 16 fixedly connected to one side of the bottom surface of the top plate 7. The cylinder barrel of the lifting cylinder 16 is installed inside the control console 6, and the piston rod of the lifting cylinder 16 extends out of the control console 6 and is fixedly connected to the top plate 7.

[0032] Specifically, a rotating gear disk 17 is fixedly connected to the outer periphery of the rotating seat 2. The driving mechanism includes a drive motor 18 fixedly mounted on the base plate 1. A drive gear 19 is fixedly connected to the power output end of the drive motor 18. A reduction gear 20 is rotatably mounted on the base plate 1 between the drive gear 19 and the rotating gear disk 17. The drive gear 19 is connected to the rotating gear disk 17 through the reduction gear 20.

[0033] Specifically, at least two locking structures for fixing the emulsifying bucket 3 are evenly arranged circumferentially on the rotating base 2. Each locking structure includes a positioning plate 21 integrally connected to the rotating base 2, and a clamping bolt 22 passing radially through the positioning plate 21. A clamping lever 23, which is easy to tighten by hand, is threaded onto the clamping bolt 22. This arrangement allows for quick and easy removal of the emulsifying bucket 3 when maintenance or replacement is required, improving the flexibility of this invention. In the above structure, a handle 24 for easy lifting is provided on the outer periphery of the emulsifying bucket 3, and a sealing gasket 25 that mates with the sealing cap 8 is provided on the top surface of the emulsifying bucket 3.

[0034] Specifically, a horizontal telescopic cylinder 26 is fixedly installed on the upper part of the outer bushing 9. The power output end of the telescopic cylinder 26 is fixedly connected to the scraper plate 15. A horizontal auxiliary slide 27 is also provided on the lower part of the outer bushing 9. An auxiliary slide rod 28, which is fixedly connected to the scraper plate 15, is coaxially provided in the auxiliary slide 27. This arrangement facilitates the deployment of the telescopic cylinder 26 when needed, allowing the scraper plate 15 to be fitted against the inner wall of the emulsification tank 3.

[0035] Specifically, a support leg 29 is fixedly connected to the bottom of the base plate 1, and a walking wheel 30 is provided at the bottom of the support leg 29 to facilitate the movement of the equipment and further improve the flexibility of use of this utility model.

[0036] Specifically, the power equipment is a power motor 31 fixedly installed above the top plate 7, and the power output end of the power motor 31 is fixedly connected to the inner rotating rod 91 through a coupling.

[0037] When using this utility model, the operator first lifts the top plate 7 using the lifting cylinder 16, then places the emulsification tank 3 on the rotating seat 2 and locks it in place by rotating the clamping block 23; then, the colorant raw material to be emulsified is added into the emulsification tank 3 according to the preset ratio, and the lifting mechanism is started through the control console 6 to drive the top plate 7 down until the sealing cover 8 is tightly attached to the sealing gasket 25 on the top of the emulsification tank 3, forming a good sealing environment and effectively preventing the leakage of materials and the mixing of external impurities during the emulsification process.

[0038] After sealing is completed, the power equipment is started. The power motor 31 drives the inner rotating rod 91 to rotate at high speed through the coupling, causing the rotor ring 13 to rotate rapidly within the stator ring 11. Due to the high-speed relative motion between the inner shear port 14 on the rotor ring 13 and the outer shear port 12 on the stator ring 11, a strong shearing force is generated, causing the material to undergo intense shearing, tearing, and mixing within the shear gap, thereby achieving efficient emulsification of the colorant. Simultaneously, the stirring blades 92 rotate with the inner rotating rod 91, further promoting the circulation of the material within the stator ring 11, preventing water accumulation, and ensuring a uniform emulsification effect.

[0039] After the emulsification process is completed, the operator first shuts off the power equipment and drive motor 18, causing the rotor ring 13 to stop rotating. Then, the lifting mechanism is controlled via control console 6, causing the piston rod of the lifting cylinder 16 to retract, raising the top plate 7 and separating the sealing cover 8 from the emulsification tank 3. At this point, the discharge valve at the bottom of the emulsification tank 3 can be opened to discharge the emulsified colorant through the discharge pipe 4, connecting it to other pipes or receiving equipment, thus completing the entire emulsification process.

[0040] When cleaning the emulsification tank 3 is required, the operator activates the telescopic cylinder 26, causing the scraper 15 to move horizontally along the auxiliary slide rail 27 under the guidance of the auxiliary slide rod 28, and adhere to the inner wall of the emulsification tank 3. At the same time, the drive motor 18 starts, and through the transmission cooperation of the drive gear 19, the reduction gear 20 and the rotating gear plate 17, it drives the rotating seat 2 to rotate the emulsification tank 3 at an appropriate speed, which facilitates the scraping off of the material adhering to the tank wall.

[0041] Furthermore, the support leg 29 of this invention is equipped with wheels 30 at its bottom, facilitating the movement of the equipment and adjustment of its position when needed, further enhancing the equipment's flexibility and convenience. The locking structure and handle 24 on the emulsifying tank 3 make installation, disassembly, and maintenance of the emulsifying tank 3 more convenient and quick, effectively improving work efficiency.

[0042] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
