Description

Technical Field

[0001] This application relates to the field of micro-processing technology, and in particular to a micro-processing process and apparatus for improving the stability of multiphase liquid food materials. Background Technology

[0002] Micronization of multiphase liquid food materials is a processing technology that reduces the size of solid particles or droplets in food materials to the micrometer level through mechanical action. Its core purpose is to fundamentally solve the problems of sedimentation, stratification, and oil-water separation in products by increasing the specific surface area of ​​the material and changing its physical and functional properties, thereby improving the physical stability of the multiphase system.

[0003] Traditional micronization processes rely on high-pressure homogenizers, but these are limited by their single shear valve or impact valve structure, resulting in low homogenization efficiency and poor reproducibility, making it difficult to precisely control particle size within the nanometer range. The resulting particle size distribution is often too wide, and there is a high risk of producing excessively large particles. These large fat globules are prone to floating or aggregating during storage, which is a major cause of poor product stability.

[0004] Therefore, it is necessary to propose a micronization process and device to improve the stability of multiphase liquid food materials. Improving the stability of materials after micronization has become an important technical problem that needs to be solved. Summary of the Invention

It aims to address the limitations of existing high-pressure homogenizers, which are constrained by their single shear valve or collision valve structure, resulting in low homogenization efficiency and poor reproducibility. This makes it difficult to precisely control particle size within the nanometer range. The particle size distribution is often too wide, and large particles are easily produced, which are prone to floating or agglomerating during storage, a major cause of poor product stability.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Example 1 See Figure 1 As shown, this application discloses a micro-processing method for improving the stability of multiphase liquid food materials. The micro-processing method specifically includes the following steps: S1, accurately weighing the continuous phase, dispersed phase, and emulsifier according to the formula, and preheating the micro-processing device; the continuous phase is a liquid such as water or oil, and the dispersed phase is a powder, oil, active ingredient, etc. Stabilizers or other additives are also required in some formulas. Taking high-value-added liquid milk as an example, it is necessary to weigh 80-98 parts of raw milk, 0.07-0.24 parts of HMOs, 0.08-0.12 parts of compound iron-zinc powder, and 0.06-0.12 parts of mono- and diglyceride fatty acid esters. The mono- and diglyceride fatty acid esters can be replaced by a mixture of mono- and diglyceride fatty acid esters, polyglycerol fatty acid esters, and propylene glycol fatty acid esters. The stirring mechanism is preheated to the homogenization temperature.

[0020] S2. Start the stirring mechanism of the micro-processing device, and add the continuous phase, dispersed phase and emulsifier in sequence to form a mixture. The stirring mechanism ensures that the mixture in the whole tank does not separate into layers or have a large concentration gradient, so as to continuously supply the material to be processed with consistent composition to the bottom and avoid the final product quality fluctuation caused by uneven feeding.

[0021] S3. After stirring, the mixture enters the high-shear structure for initial homogenization. After initial stirring, the rotor 32 in the high-shear structure begins to rotate. As the rotor 32 rotates at high speed inside the stator 34, a low-pressure zone is formed in its central area, and the mixture is continuously drawn into the center of the rotor 32. Upon entering, the mixture is immediately captured by the high-speed rotating rotor 32. The rotor 32 impacts the mixture, generating strong shear and causing it to rotate. As the speed of the mixture increases, under the action of strong centrifugal force, the mixture is thrown at high speed from the center towards the outer edge of the rotor 32. During this process, the mixture is accelerated to an extremely high linear velocity almost the same as the tip of the outer edge of the rotor 32. The mixture moves at extremely high speed with the rotor 32, while the stator 34 remains stationary. After the fluid is thrown out of the stator 34 holes at high speed, it impacts the relatively stationary stator 34 on the outside. This collision will generate strong shearing on the mixture, causing the dispersed phase and other additives in the mixture to be torn and broken into smaller droplets or particles. In addition, the above collision will also generate strong turbulence, which will cause violent collisions and friction between the torn and broken tiny particles and between the particles and the liquid, further carrying out hydrodynamic erosion and making the particle size distribution more uniform.

[0022] S4. The mixture is thrown into the Y-shaped orifice by the high-shear structure for secondary homogenization; the mixture thrown out at high speed by the gap between rotor 32 and stator 34 is forced into the Y-shaped orifice on stator 34. It will first be evenly split into the two branch channels 35 of the Y-shape. The two micro-jets collide at the intersection of the Y-shaped channels. During the collision, the mixture particles or droplets are directly impacted at the collision point, causing deformation and breakage. Furthermore, during the collision, the high velocity of the fluid is forcibly converted into extremely high local pressure. After the collision, the fluid will rapidly diffuse outward from this high-pressure center, and the pressure will decrease sharply, thereby triggering a strong cavitation effect and huge shear force, which completely tears apart the droplets or particles, further homogenizing the mixture.

[0023] S5. The mixture, after secondary homogenization, is pumped back into the stirring mechanism for further homogenization. This repeated homogenization of the material results in a final product with an extremely narrow particle size distribution and excellent stability.

[0024] The cycle time can be determined based on experience, and the homogenization operation can be stopped once the cycle time reaches the target. Alternatively, an online laser particle size analyzer can be used to detect the particle abundance in the mixture in real time, and the cycle can be stopped once the particle abundance reaches the target.

[0025] Specifically, this application utilizes a stirring mechanism to ensure that the entire mixture in the tank does not stratify or exhibit large concentration gradients, providing a continuous supply of uniformly composed materials to the lower part of the tank and avoiding fluctuations in final product quality caused by uneven feeding. A high-shear structure and Y-shaped orifices thoroughly break down droplets or particles, effectively homogenizing the mixture. Furthermore, the material is repeatedly homogenized, resulting in a final product with an extremely narrow particle size distribution and excellent stability.

[0026] Example 2 In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0027] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment discloses a micronization treatment device for improving the stability of multiphase liquid food materials. The micronization treatment process in Embodiment 1 is implemented through the micronization treatment device, which includes: a frame 1; the frame 1 is the structural foundation of the micronization treatment device, and other structures on the micronization treatment device are directly or indirectly installed on the frame 1; a mixing tank 26, which is disposed on the frame 1; a mixing cover 4, which is disposed on the mixing tank 26; a mixing drive 16, which is disposed on the mixing cover 4; and a mixing shaft 29, which is connected to the mixing drive 16 and partially located inside the mixing tank 26; the mixing tank 26, the mixing cover 4, the mixing shaft 29, and the mixing drive 16 together constitute a mixing mechanism. The mixing cover 4 is provided with a dry material inlet 10 and a liquid phase inlet, and multiple liquid phase inlets are provided to facilitate the simultaneous feeding of multiple liquid phases. The mixing tank 26 has openings at both the upper and lower ends, and the opening at the upper end of the mixing tank 26 is closed by the mixing tank 26 itself. The stirring shaft 29 is rotatably mounted on the stirring cover 4 via a first bearing support. A support frame 2 is connected to the end of the first bearing support. A reducer 15 is installed inside the support frame 2. The reducer 15 is connected to the stirring shaft 29. The stirring drive 16 is specifically a motor. The motor shaft of the stirring drive 16 is also connected to the reducer 15. The stirring drive 16 drives the stirring shaft 29 to rotate through the reducer 15, thereby completing the stirring of the mixture in the stirring tank 26.

[0028] Shear chamber 41 is located at the bottom of the mixing tank 26; shear drive 24 is located at the bottom of the shear chamber 41; rotor 32 is rotatably installed inside the shear chamber 41 and connected to the shear drive 24; stator 34 is installed inside the shear chamber 41; the shear chamber 41, shear drive 24, rotor 32 and stator 34 form a high shear structure, and the opening at the lower end of the mixing tank 26 is connected to the shear chamber 41, so that the liquid in the mixing tank 26 can flow into the shear chamber 41 under the action of gravity. The shearing drive 24 is specifically a motor. The motor shaft of the shearing drive 24 is connected to the rotor shaft 25 of 32 via a coupling. The rotor shaft 25 is connected to the rotor 32 by welding. The outer circumference of the rotor 32 has four protrusions spaced apart. The protrusions facilitate better shearing of the mixture by the rotor 32 and help increase the diameter of the rotor 32. With the rotational speed remaining constant, the linear velocity of the outer edge of the rotor 32 can be increased, thereby increasing the linear velocity of the mixture thrown out of the rotor 32. The bottom of the shearing chamber 41 is connected to a second bearing support by fasteners. The second bearing support is rotatably connected to the rotor shaft 25 of 32. A mechanical seal is provided between the second bearing support and the rotor shaft 25 of 32. The mechanical seal and the second bearing support are mature existing technologies, and their specific structures are not limited here. A protective cover 6 is also provided at the bottom of the shearing chamber 41 to protect the shearing drive 24.

[0029] It can be understood that upon entering the mixture, it is immediately captured by the high-speed rotating rotor 32. The rotor 32 impacts the mixture, generating strong shear and causing it to rotate. As the mixture's velocity increases, under the powerful centrifugal force, it is thrown at high speed from the center towards the outer edge of the rotor 32. During this process, the mixture is accelerated to an extremely high linear velocity almost identical to the tip of the outer edge of the rotor 32. The mixture moves at extremely high speed with the rotor 32, while the stator 34 remains stationary. After being thrown out of the stator 34's holes at high speed, the fluid impacts the relatively stationary stator 34. This collision generates strong shear in the mixture, tearing the dispersed phase and other additives into smaller droplets or particles. Furthermore, these collisions generate strong turbulence, prompting intense collisions and friction between the torn and broken particles and between the particles and the liquid, further promoting hydrodynamic erosion and resulting in a more uniform particle size distribution.

[0030] Y-shaped orifices are formed on the stator 34. Specifically, the Y-shaped orifice includes two branch channels 35 and a main channel 33. The mixture collides at the intersection of the two branch channels 35 and is discharged from the main channel 33. During the collision, the mixture particles or droplets are directly impacted at the collision point, causing deformation and breakage. Furthermore, the high velocity of the fluid is forcibly converted into extremely high local pressure during the collision. After the collision, the fluid rapidly diffuses outward from this high-pressure center, and the pressure decreases sharply, thus triggering a strong cavitation effect and enormous shear force, completely tearing apart the droplets or particles and further homogenizing the mixture.

[0031] A circulating pump 8 is connected to a shear chamber 41 via a pipeline; a return pipeline 9 is connected to the circulating pump 8, and the return pipeline 9 is connected to the mixing tank 26. An outlet pipeline is provided on the outside of the shear chamber 41, and the outlet pipeline is connected to a tee pipeline 5 via a flange. One outlet of the tee pipeline 5 is connected to the circulating pump 8 via a flange. The circulating pump 8 is connected to the return pipeline 9 via a flange. The end of the return pipeline 9 away from the circulating pump 8 is connected to the mixing tank 26. The mixture discharged from the Y-shaped orifice main channel 33 can flow back to the mixing tank 26 under the action of the circulating pump 8 for circulation and homogenization.

[0032] Preferably, in the Y-shaped hole, the diameters of the two branch channels 35 gradually decrease, allowing the mixture to be further accelerated in the branch channels 35, thereby improving the subsequent collision homogenization effect.

[0033] See Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, in some embodiments, the micro-processing device further includes: a jacket 11, which is disposed on the outer side of the mixing tank 26; the jacket 11 is connected to the outer side of the mixing tank 26 by welding. A first temperature control inlet 14 is disposed at the top of the jacket 11; a second temperature control inlet 12 is disposed at the bottom of the jacket 11; a temperature control outlet 13 is disposed at the middle of the jacket 11; and a spiral wall 27 is disposed on the outer side of the mixing tank 26, which is fitted to the jacket 11. The spiral wall 27, the jacket 11, and the outer peripheral surface of the mixing tank 26 form a spiral flow channel, and the first temperature control inlet 14, the second temperature control inlet 12, and the temperature control outlet 13 are all connected to the spiral flow channel. The temperature-controlled medium enters the spiral flow channel from the first temperature control inlet 14 and the second temperature control inlet 12, and is finally discharged from the temperature control outlet 13. During the homogenization process, the homogenization temperature needs to be controlled. For high-value-added liquid emulsions, the homogenization temperature needs to be maintained between 55℃ and 65℃ to effectively break down fat globules while minimizing the denaturation and aggregation of high-concentration proteins. A constant-temperature control medium is used to maintain the homogenization temperature, preventing excessively high or low temperatures from affecting the quality of the final product.

[0034] The spiral wall 27 forces the temperature-controlled medium to flow in a spiral pattern along the outside of the mixing tank 26, ensuring uniform flow rate and heat exchange. This also helps increase the heat exchange efficiency between the temperature-controlled medium and the mixing tank 26. The placement of the first temperature control inlet 14 and the second temperature control inlet 12 helps reduce the heat exchange time of the temperature-controlled medium, preventing temperature anomalies caused by prolonged heat exchange and ensuring the medium does not exceed the homogenization temperature range.

[0035] The temperature control outlet 13 is located close to the second temperature control inlet 12. The temperature control medium in the second temperature control inlet 12 needs to overcome gravity and flow upwards, resulting in a slow flow speed. The temperature control outlet 13 is closer to the second temperature control inlet 12, so that the heat exchange time of the temperature control medium discharged from the second temperature control inlet 12 will not be too long.

[0036] See Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the micro-processing device further includes: a stirring frame 39, which is disposed on the outer side of the stirring shaft 29; the stirring frame 39 is connected to the outer side of the stirring shaft 29 by welding. A wall scraper 40 is disposed on the stirring frame 39 and fits against the inner wall of the mixing tank 26; the wall scraper 40 is installed on the stirring frame 39 by fasteners such as bolts. Multiple wall scrapers 40 are provided, and the multiple wall scrapers 40 are arranged at intervals. Multiple stirring paddles 36, some of which are disposed on the stirring frame 39, and others are disposed on the outer side of the stirring shaft 29. The stirring paddles 36 are connected to the stirring frame 39 by welding. The stirring frame 39 and the stirring paddles 36 are used to stir the mixture in the mixing tank 26, and the wall scraper 40 on the stirring frame 39 continuously scrapes off the material that is in close contact with the inner wall of the mixing tank 26, which can eliminate dead zones and significantly improve heat transfer efficiency, preventing material coking and scaling.

[0037] See Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the micro-processing device further includes: a serrated end 37, the end of the agitator 36 is provided with a serrated end 37; and a stirring hole 38, a stirring hole 38 is formed on the agitator 36. The serrated end 37 acts like a miniature claw, providing initial shearing to break the dispersed phase in the mixture into more manageable fragments. The stirring hole 38 on the agitator 36 allows some fluid to pass through the high-pressure surface, and the fluid passing through forms a jet, precisely breaking up localized clumps around the agitator 36, eliminating wake cavities on the back of the agitator 36, and reducing the energy consumption and vibration required for agitation.

[0038] See Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the miniaturization device further includes: A filter screen 30 is installed at the bottom of the mixing tank 26. The filter screen 30 is welded to the bottom opening of the mixing tank 26 and is used to filter the material discharged from the mixing tank 26. The filter screen 30 can intercept hard foreign objects accidentally mixed in during the raw materials or pretreatment, providing mechanical overload protection for the precision stator 34, rotor 32 clearances and Y-shaped holes, preventing catastrophic structural wear. Furthermore, the filter screen 30 can effectively intercept large particles exceeding the clearance scale that cannot be completely eliminated by macro-mixing within the mixing tank 26, preventing these materials from clogging the Y-shaped holes and ensuring the smooth and stable operation of the forced circulation and homogenization process throughout.

[0039] Understandably, filter 30 physically intercepts all particles exceeding the target particle size, providing downstream high-shear homogenization with uniform pre-materials of controlled particle size. This is a crucial technological prerequisite for achieving uniform final particle size and eliminating large particles from exceeding the standard. Furthermore, filter 30 also acts as a flow field rectifyer and eddy current suppressor, providing more stable inlet conditions for high-shear structures.

[0040] A seal 31 is provided between the stator 34 and the shear chamber 41. The sealing ring forms a sealing barrier between the stator 34 and the shear chamber 41, forcing all material to pass 100% through the Y-shaped orifice. It also maintains the high pressure differential required for the collision of the Y-shaped orifice, concentrating the kinetic energy of the fluid for effective crushing, rather than letting it leak out through the gaps.

[0041] See Figure 2 , Figure 3 and Figure 8 As shown, in some embodiments, the stator 34 includes: a first segment having a first Y-shaped groove; and a second segment connected to the first segment by welding, the second segment having a second Y-shaped groove, the second Y-shaped groove and the first Y-shaped groove combining to form a Y-shaped hole. The first Y-shaped groove and the second Y-shaped groove are milled on the joint surface of the first and second segments. After machining, the first and second segments are joined together, and electron beam welding, laser welding, or vacuum diffusion welding are used to permanently fuse the first and second segments into a single unit along the outer contour. The welded stator 34 is a completely dense metal unit, avoiding leakage problems.

[0042] See Figure 4 and Figure 5As shown, in some embodiments, the micro-processing device further includes: a lifting frame connected to the stirring cover 4; and a lifting drive 23 mounted on the frame 1 and connected to the lifting frame. Specifically, the lifting drive 23 is a motor, connected to a screw 19 via a reducer 15. A nut block 22 is screwed onto the screw 19, and a lifting arm 21 is connected to the nut block 22 via fasteners. The lifting arm 21 is connected to a support frame 2. A first guide cylinder 17 is provided on the frame 1 to guide the support frame 2. A slide rod 20 is connected to the support frame 2 via fasteners, and a second guide cylinder 18 adapted to the slide rod 20 is provided on the frame 1.

[0043] The stirring cover 4 is provided with a positioning groove, and the stirring tank 26 is provided with a positioning protrusion that matches the positioning groove.

[0044] See Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the microprocessing device further includes: a sight glass 3, which is disposed on the stirring cover 4; the sight glass 3 is used to observe the condition inside the stirring tank 26. A pressure sensor, which is disposed on the stirring cover 4, is used to detect the pressure inside the stirring tank 26. The stirring cover 4 is also provided with a rinsing pipe, and the end of the rinsing pipe is provided with a spray head 28 for easy cleaning of the stirring tank 26.

[0045] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the miniaturization device further includes mounting feet 7, which are provided on the frame 1. Multiple mounting feet 7 are spaced apart on the frame 1, allowing the frame 1 to be stably placed on the ground.
