[0003] Generally speaking, special dietary drinks contain at least two or more different types of purees. Since different types of purees have different ingredients, the use of ordinary mixing methods will result in insufficient mixing, making it difficult to achieve the homogeneous requirements for drinking. The prior art generally uses a high-pressure homogenizer, a high-shear emulsifier or a micro-jet homogenizer to mix the special dietary drink purees. Among them, the high-pressure homogenizer cannot achieve the effect of dispersion and grinding due to its low pressure; the micro-jet homogenizer has a small flow rate; the high-shear emulsifier has a strong stirring effect and it is difficult to achieve the homogenization requirements. Therefore, the above-mentioned equipment alone cannot achieve the industrial production requirements of special dietary drinks. In order to achieve nano-level mixing and homogenization effects, it is usually necessary to use a variety of homogenization equipment and methods according to the process, which leads to cumbersome processing steps, low processing efficiency, and difficult to control the processing process.

DETAILED DESCRIPTION

[0048] Among the related technologies that have been retrieved:

[0049] The overview of the high pressure homogenizer is as follows:

[0050] The material is sucked into the valve group through the continuous reciprocating motion of the plunger pump. The material flows through the gap under high pressure. The droplets are first extended, and then the extended part is sheared and broken due to the turbulence. The high-speed liquid flow rushing out of the valve gap hits the retaining ring, producing a high-speed impact. At the same time, the pressure drops rapidly and sharply, generating a large explosive force, instantly causing cavitation. The strong release of energy and strong high-frequency vibrations break the particles or droplets, thereby achieving the effect of homogenizing, crushing and emulsifying the liquid sample. The price is relatively low, and it is more suitable for processing soft and semi-soft granular materials, but the homogenizing valve of the homogenizer is designed with a large gap and a low homogenizing pressure. It is easy to be damaged when homogenizing high-hardness particles, and it is difficult to repair.

[0051] An overview of the high shear homogenizer is as follows:

[0052] The shearing head is composed of a rotor and a stator, which mesh with each other, and each level of the stator and rotor has several layers of gear rings. The high-speed rotation of the rotor generates a strong centrifugal force, forming a strong negative pressure area. The material is sucked into the working chamber and is subjected to shearing, centrifugal extrusion, impact tearing and turbulence in the gap between the stator and the rotor, which generates tension for splitting droplets. After the liquid leaves the small hole of the stator, the pressure rises again, thus producing a cavitation effect. The homogenizing head rotates at high speed to shear, disperse and impact the material to complete the homogenization. The processing capacity is large, the product stability is good, it is not easy to destroy the emulsion layer, the machine is relatively durable and easy to maintain, and the homogenization form is more abundant. The disadvantage is that the volume is relatively large.

[0053] The overview of the Microfluidizer is as follows:

[0054] The micro-jet high-pressure homogenizer is mainly composed of a dispersion unit and a booster mechanism. Under the action of the booster mechanism, the fluid passes through a valve core with a very small aperture using the high pressure generated by the hydraulic pump, generating a fluid at several times the speed of sound, and quickly passes through the narrow gap of the dispersion unit, performing a strong high-speed impact. During the impact process, the fluid instantly converts most of its energy, and the pressure in the fluid drops sharply to form a supersonic fluid. The particles in the fluid collide, cavitate and turbulent, and the shear force acts on the nano-sized fine molecules, making the components of the fluid exist in a completely homogenous state. Sufficient homogenization pressure can produce a better particle size distribution effect. However, its flow rate is small and the cost is relatively high.

[0055] The above-mentioned homogenizers each have their own advantages and disadvantages, but none of them can independently achieve the nano-level homogenization effect of special diet drink puree. They need to be used in coordination with other equipment to jointly meet the homogenization requirements.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] Example 1

[0059] The embodiment of the present invention provides an integrated graded homogenization structure; the ultrasonic emulsification module 1 is composed of a separation chamber 101 and an ultrasonic emulsification vibration screen 102. The upper end of the separation chamber 101 is connected to a plurality of raw pulp storage tanks 3 through a controllable high-pressure pump 2, and the lower end is connected to the upper opening of the variable diameter chamber 5; the controllable high-pressure pump 2 can send a variety of raw pulps from the raw pulp storage tank 3 into the separation chamber 101 according to the raw pulp ratio of the special dietary drink, and the pumping pressure can be adjusted according to actual needs. The ultrasonic emulsification vibration screen 102 is horizontally arranged in the separation chamber 101, and the setting position is close to the upper part. The ultrasonic emulsification vibration screen 102 is electrically connected to the ultrasonic high-frequency vibration generator 103, and the ultrasonic high-frequency vibration generator 103 is powered by an ultrasonic power supply 104. The raw pulp is vibrated and mixed by the ultrasonic emulsification vibration screen 102 to form an emulsified stock solution, and the emulsified stock solution can pass through the ultrasonic emulsification vibration screen 102 and continue to flow downward along the separation chamber 101.

[0060] A micron-scale flow channel and a vortex chamber 401 are defined inside the high-pressure microfluidic module 4. The micron-scale flow channel is connected to the ultrasonic emulsification module 1 and the vortex chamber 401 respectively. The controllable high-pressure pump 2 can pump the emulsified stock solution into the micron-scale flow channel and form a high-speed stock solution microjet; the atomizing vortex component is arranged in the vortex chamber 401, and the atomizing vortex component corresponds to the micron-scale flow channel and can atomize the high-speed stock solution microjet to form a vortex.

[0061] In this embodiment, the atomizing vortex component includes: a plurality of micron-sized flow guide devices 402, which are installed at the feed port of the vortex chamber 401, and the micron-sized flow channel is arranged in the micron-sized flow guide device 402; a high-speed stock liquid microjet flows into the vortex chamber 401 from the micron-sized flow channel and forms a microjet middle flow and a microjet side flow. It should be noted that the microjet middle flow and the microjet side flow are essentially the same, and the only difference is that the microjet side flow is located on the outside of the microjet middle flow. From the flow rate point of view, the flow rate of the microjet middle flow is greater than that of the microjet side flow. The microjet crushing spacer 403 is arranged in the vortex chamber 401 and corresponds to the microjet middle flow. The microjet middle flow collides with the microjet crushing spacer 403 and atomizes the microjet middle flow. When the microjet side flow is injected into the vortex chamber 401, due to the sudden increase of space, according to the Bernoulli principle, the microjet side flow will form a vortex in the vortex chamber 401 and mix with the atomized microjet middle flow to form a mixed atomized stock liquid.

[0062] In this embodiment, it also includes: a variable diameter chamber 5, which is located between the ultrasonic emulsification module 1 and the high-pressure microjet module 4, and is generally a cylindrical chamber with upper and lower openings. The cross-sectional area of ​​the variable diameter chamber 5 gradually decreases from the upper opening to the lower opening (similar to a cone), and the upper opening is connected to the bottom of the separation chamber 101, and the lower opening is connected to the micron-level flow channel.

[0063] In this embodiment, an electrophoresis separation module 6 is also included, and the electrophoresis separation module 6 includes a primary filter screen 601 and an electrophoresis auxiliary electrode 602. The bottom of the separation chamber 101 is connected with a stock solution pipe 1011 and an impurity solution pipe 1012, the stock solution pipe 1011 is close to the middle of the separation chamber 101, the impurity solution pipe 1012 is close to the inner wall of the separation chamber 101, and the stock solution pipe 1011 is connected with the upper opening of the variable diameter chamber 5; the primary filter screen 601 is arranged in the separation chamber 101 and is located between the ultrasonic emulsification vibration screen 102 and the bottom of the separation chamber 101. The electrophoresis auxiliary electrode 602 is disposed on the separation chamber 101 and can form an auxiliary electric field between the primary filter screen 601 and the bottom of the separation chamber 101. The auxiliary electric field can adsorb nano-scale impurities in the emulsified stock solution to a position close to the inner wall of the separation chamber 101 and precipitate downward to be discharged from the impurity solution tube 1012. The emulsified stock solution after the nano-scale impurities are removed enters the variable diameter chamber 5 from the stock solution tube 1011. The liquid discharged from the impurity solution tube 1012 contains a certain amount of recyclable emulsified stock solution, which can be used again for the preparation of special dietary drinks after further removing the nano-scale impurities.

[0064] In the present embodiment, it also includes: a vortex mixing chamber 7, which has a plurality of liquid inlet pipes 8 arranged circumferentially near the top, and the liquid inlet pipes 8 are connected to the discharge port of the vortex chamber 401; a vortex solution collection pipe 701 is arranged at the bottom center of the vortex mixing chamber 7; a plurality of wing-type isolation plates 9 are arranged circumferentially in the vortex mixing chamber 7, and the wing-type isolation plates 9 have a straight inner side surface and an arc-shaped outer side surface; the outer side surface of the wing-type isolation plate 9 is provided with a super-hydrophobic micro-texture, and the inner side surface of the wing-type isolation plate 9 is provided with a super-hydrophilic micro-texture. The outer side surface of the wing-type isolation plate 9 is crest-shaped, and the liquid outlet direction of the liquid inlet pipe 8 is generally toward the highest position of the outer side surface of the wing-type isolation plate 9. The mixed atomized stock solution flows into the vortex mixing chamber 7 through the liquid inlet pipe 8, and a flow velocity difference is formed on the outer side and the inner side surface of the wing-type isolation plate 9 to generate a vortex. The specific principle is as follows:

[0065] When the mixed atomized stock solution flows through the outer side of the wing-type isolation plate 9, the super-hydrophobic micro-texture can reduce the bonding resistance between the mixed atomized stock solution and the wing-type isolation plate 9; on the contrary, when the mixed atomized stock solution flows through the inner side of the wing-type isolation plate 9, the super-hydrophilic micro-texture can increase the bonding resistance between the mixed atomized stock solution and the wing-type isolation plate 9. In such a structural form, a flow velocity difference will be generated between the inner side and the outer side of the wing-type isolation plate 9, thereby causing the mixed atomized stock solution to generate a vortex.

[0066] The present embodiment also includes: an annular mixed flow conduit 10, one end of which is connected to the vortex solution collecting pipe 701, and the other end is connected to the liquid collecting tank 11. The annular mixed flow conduit 10 is arranged in a spiral manner, which can force the liquid to rotate and mix.

[0067] Based on the above structure, an embodiment of the present invention also provides an integrated grading and homogenizing method, including the following steps:

[0068] S1: Multiple stock storage tanks 3 pump multiple stock into the separation chamber 101 through the controllable high-pressure pump 2 according to the preset ratio, and the ultrasonic emulsification vibration screen 102 vibrates and mixes the multiple stock to form an emulsified stock solution and filters out a small amount of impurities (larger particles). The mesh of the ultrasonic emulsification vibration screen 102 should be flexibly adjusted according to the actual use situation to ensure that the emulsified stock solution after vibration mixing can pass through and enter the next process;

[0069] S2: The emulsified stock solution passes through the primary filter screen 601 to filter out large particles of impurities;

[0070] S3: the emulsified stock solution enters the auxiliary electric field, which adsorbs the nano-scale impurities in the emulsified stock solution to a position close to the inner wall of the separation chamber 101 and discharges the nano-scale impurities from the impurity solution pipe 1012. The emulsified stock solution after the nano-scale impurities are removed enters the variable diameter chamber 5 from the stock solution pipe 1011.

[0071] S4: the cross-sectional area of ​​the variable diameter chamber 5 gradually decreases from the upper opening to the lower opening, and the flow velocity of the emulsified stock solution gradually increases and flows from the lower opening into the micron-sized flow channel to form a high-speed stock solution microjet;

[0072] S5: The high-speed stock solution microjet flows from the micron-sized flow channel into the vortex chamber 401 to form a microjet middle flow and a microjet side flow outside the microjet middle flow. The microjet middle flow collides with the microjet crushing spacer 403 to be atomized. When the microjet side flow flows into the vortex chamber 401, the flow space increases, and a vortex is formed in the vortex chamber 401 based on the Bernoulli principle. The vortex is mixed with the atomized microjet middle flow to form a mixed atomized stock solution.

[0073] S6: The mixed atomized stock solution enters the vortex mixing chamber 7 along the circumferential direction through a plurality of liquid inlet pipes 8, and a flow velocity difference is formed on the outer side and the inner side of the wing-type isolation plate 9 to generate a vortex, and the mixed atomized stock solution is homogenized to form a pre-finished product liquid;

[0074] S7: The pre-finished liquid flows into the annular mixed flow conduit 10 through the vortex solution collection tube 701, rotates and mixes in the annular mixed flow conduit 10 to form a finished liquid and is discharged to the liquid collection tank 11.

[0075] The equipment and method disclosed in Example 1 were used to homogenize the special dietary drink puree, which was made of prune concentrate, green plum and coix seed. The homogenization state of the finished liquid was observed and the time of homogenization completion was recorded. The results were as follows:

[0076]

[0077] Example 2

[0078] The difference between this embodiment and embodiment 1 is that the outer side of the wing-type isolation plate 9 is coated with a super-hydrophobic coating, and the inner side is coated with a super-hydrophilic coating.

[0079] Example 3

[0080] The difference between this embodiment and embodiment 1 is that a temperature-controlled memory metal baffle plate 12 is provided on the inner side of the wing-type isolation plate 9. The temperature-controlled memory metal baffle plate 12 can be connected to an external power source through a wire (electrically controlled temperature) or directly exchange heat with the atomized stock liquid entering the vortex mixing chamber 7. When the temperature of the temperature-controlled memory metal baffle plate 12 changes, it can deform, and after deformation, it can change the channel width between adjacent wing-type isolation plates 9, thereby changing the flow rate of the liquid when it flows through the channel, accelerating the vortex forming process, and improving the homogenization effect and homogenization efficiency.

[0083] The outer surface of the machine body 13 is provided with connecting threads or other connecting structures, which can connect multiple machines 13 in series. When the raw pulp is homogenized in the previous machine body 13, it can enter the next machine body 13 for homogenization again, realizing multi-stage homogenization and enhancing the homogenization effect.
