Description

Technical Field

[0001] The present invention relates to the technical field of homogenization processing, and in particular to an ultrasonic atomization micro-jet special dietary drink nano-homogenization device and method. Background Art

[0002] At a time when health awareness is increasingly awakening, the concept of medicine and food having the same origin is gradually gaining popularity and becoming an important force in promoting the development of the modern nutrition and health industry. This ancient and wise tradition emphasizes the natural connection between food and medicine, and advocates conditioning the body through daily diet to prevent diseases and strengthen the body. Modern nutritional products combine the nutrients of medicine and food to make better-absorbed special dietary health drinks, aiming to condition the body, prevent diseases and strengthen the body through daily diet. Different drugs have different characteristics, which can easily lead to insufficient mixing during the manufacturing process of special dietary drinks, poor solution stability, more precipitation, and reduced utilization of effective ingredients. Therefore, solution homogenization during the manufacturing process becomes particularly important.

[0003] Homogenization, also known as homogenization, is the process of micronizing and homogenizing the dispersed matter in the suspension (or emulsion) system. This treatment simultaneously reduces the size of the dispersed matter and improves the uniformity of the dispersed matter distribution. Homogenization is a technology often used in the production of the pharmaceutical or chemical industry. It refers to the process of refining the material under the triple effects of extrusion, strong impact and decompression expansion, so that the materials can be mixed more evenly.

[0004] The existing technology usually uses high-pressure homogenizers, high-shear emulsifiers and micro-jet homogenizers for homogenization. However, high-pressure homogenizers generally have the defect of large design gaps in the homogenization valve, which leads to low homogenization pressure, easy damage when processing high-hardness particles, and difficulty in maintenance. The technical defect of the high-shear emulsifier is its large size. Although the processing volume is large and the product stability is good, the size of the machine limits its application in environments with limited space. The technical defect of the micro-jet homogenizer is that the design pressure is high, resulting in a small flow rate, and the cost is relatively high, which limits its widespread use in cost-sensitive applications.

[0005] Therefore, it is necessary to propose an ultrasonic atomization micro-jet special dietary drink nano-homogenization device and method. Summary of the invention

[0037] 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.

[0038] The prior art generally uses a high-pressure homogenizer, a high-shear emulsifier and a microfluidizer to perform homogenization.

[0039] High-pressure homogenizers mainly use the high pressure of the pressure system to squeeze, extend, impact, and crush materials, mainly relying on the cavitation effect and turbulence effect. Its working principle is: through the continuous reciprocating motion of the plunger pump, the material is sucked into the valve group, and the material flows through the gap under high pressure. The droplets are first extended, and then due to the turbulence, the extended part is sheared and broken. 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, and 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. However, the homogenizing valve of the high-pressure homogenizer is designed with a large clearance and a low homogenizing pressure. It is easy to be damaged when homogenizing high-hardness particles and is difficult to repair. The advantage is that the price is relatively low. High-pressure homogenizers are more suitable for processing soft and semi-soft granular materials.

[0040] The high shear emulsifier mainly relies on the high shear effect generated by the relative high-speed movement between the stator and the rotor to shear, tear and mix the materials. At the same time, the strong cavitation effect disperses, refines and homogenizes the material particles. The shear head of the high shear emulsifier consists of a rotor and a stator. The rotor and the stator are meshed 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 generating a cavitation effect. The homogenizing head rotates at high speed to shear, disperse and impact the material to complete the homogenization. Its advantages are large processing capacity, good product stability, not easy to destroy the emulsion layer, more durable and easy to maintain machine, more abundant homogenization forms, and disadvantages are relatively large volume.

[0041] 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 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 homogenized state. The micro-jet homogenizer uses a channel of about 100 microns to form a supersonic jet. The jets collide with each other, and perform extremely strong shearing to obtain a higher homogenization pressure and produce a better particle size distribution effect. However, its design pressure is high, the flow rate is small, and the cost is relatively high.

[0042] In view of the shortcomings of the above-mentioned prior art, the present invention develops a special dietary drink concentrate homogenizing device and method with microjet assisted ultrasonic synergistic atomization by utilizing the characteristics of microjet homogenizer, which has good homogenizing effect but small flow rate. The ultrasonic frequency is controlled to enhance the solution atomization flow rate, which is synergistically mixed with the microjet, and then an annular cooling mixing channel is used to further condense and fuse different types of drugs to form a nano-scale homogenized special dietary drink, thereby achieving the effect of improving solution stability, reducing precipitation, and increasing the utilization rate of effective ingredients.

[0043] 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.

The inside of the water tank 4 is divided into several raw pulp storage chambers to ensure sufficient supply of raw liquid. For example, in this embodiment, the raw pulp storage chamber 1 3 and the raw pulp storage chamber 2 13 are described as examples. The raw pulp storage chamber 1 3 and the raw pulp storage chamber 2 13 can respectively store the raw liquid of the special dietary drink that needs to be mixed and homogenized, and the purpose of mixing multiple raw liquids can also be achieved by adding raw pulp storage chambers. The raw pulp storage chamber is connected to the primary mixing chamber 6 through an infusion tube, and a high-pressure pump 5 is installed on the infusion tube. One end of the infusion tube is connected to the raw pulp storage chamber 1 3, and the other end is connected to the primary mixing chamber 6, and a high-pressure nozzle 8 is installed at one end of the infusion tube entering the primary mixing chamber 6, and the output flow and output pressure of the high-pressure nozzle 8 can be controlled by the control circuit 20.

The upper part is connected to the mixing cooler 11 through the mixing conduit 10. The outlet of the mixing cooler 11 is connected to the liquid collecting tank 12.

The main power supply 17 is electrically connected to the water level controller 15, the mist volume controller 16, the humidity controller 18, the ultrasonic transducer 19, the control circuit 20, etc. to provide power to the entire homogenization system. The control circuit 20 controls the output power and amplitude of the ultrasonic transducer 19 according to the homogenization requirements, ensures the ultrasonic atomization size, and meets the homogenization requirements. The humidity of the homogenization equipment environment is controlled by the humidity controller 18 to avoid environmental pollution. The input amount of the water control valve 14 entering the raw pulp storage chamber is controlled by the mist amount controller 16.

[0045] In a specific embodiment, a plurality of temperature sensors 2 are installed at the bottom of the water tank 4 to monitor the temperature change of the raw pulp storage chamber in real time to ensure the activity of the effective substances in the raw pulp.

[0046] In a specific embodiment, the ultrasonic transducer 19 is installed in the atomization chamber at the bottom of the water tank 4, and can generate high-frequency vibrations. The high-frequency acoustic vibrations of the ultrasonic transducer 19 act on the solution, destroying the surface of the solution to generate oscillation waves, thereby generating nano-scale aerosols on the surface of the solution.

[0047] In a specific embodiment, the water level controller 15 is installed in the atomization chamber at the bottom of the water tank 4 to control the height of the solution on the surface of the ultrasonic transducer 19 to optimize the atomization performance of the ultrasonic transducer 19 .

[0048] In a specific embodiment, the mist volume controller 16 is connected to the control circuit 20 to indirectly control the output power and amplitude of the ultrasonic transducer 19 according to the required output flow rate.

[0049] In a specific embodiment, the top of the atomization chamber is connected to the second raw pulp storage chamber 13 through a water control valve 14. The valve opening size can be adjusted in real time according to the feedback data of the mist volume controller 16 to control the input volume of the second raw pulp storage chamber 13.

[0050] In a specific embodiment, a dual-channel blower 7 is provided on one side of the primary mixing chamber 6, and two air outlets of the dual-channel blower 7 are respectively connected to the primary mixing chamber 6 and the mixed flow duct 10, and the air outlet connected to the primary mixing chamber 6 faces the high-pressure nozzle 8 in the primary mixing chamber 6. The dual-channel blower 7 is a flow-controllable blower, which is automatically controlled by the control circuit 20, and the output air volume can be controlled according to the homogenization requirements.

[0051] In a specific embodiment, a mixing microchannel 21 is provided in the mixing cooler 11 to ensure that the atomized homogenized stock solution has a sufficiently long mixing flow path during its flow, thereby ensuring sufficient cooling while achieving further mixing of different stock solutions.

[0052] In some optional embodiments, a patch semiconductor cooling plate 22 is provided on the mixing microchannel 21 , and the patch semiconductor cooling plate 22 is controlled by an adaptive cooling power supply 23 to ensure that the atomized homogenized stock solution in the mixing microchannel 21 is quickly cooled and liquefied.

[0053] In some optional embodiments, the mixing cooler 11 is a spiral cooler or an annular cooler.

[0054] In some optional embodiments, a crushing spacer 9 is installed in the water tank 4 above the outlet of the high-pressure nozzle 8. The high-pressure nozzle 8 and the crushing spacer 9 are installed together to ensure that the high-pressure micro-jets are accurately directed to the crushing spacer 9. At the same time, the droplets can be further atomized with the help of the airflow output by the dual-channel blower 7.

[0055] The working principle and beneficial effects of the ultrasonic atomization micro-jet special dietary drink nano-homogenization device of the embodiment of the present invention are as follows:

[0056] The control circuit 20 controls the stable operation of the ultrasonic transducer 19, the water control valve 14, the water level controller 15, the mist controller 16, the humidity controller 18, and the temperature controller. The high-pressure pump 5 forms a micro jet with the raw liquid in the raw pulp storage chamber through the high-pressure nozzle 8, and uses the compressed air provided by the flow-controllable dual-channel blower 7 to form a high-speed airflow through a small pipe mouth. The negative pressure generated drives the raw liquid to be sprayed onto the crushing partition 9, and is broken into small aerosol particles under high-speed impact. The larger droplets hit the baffle and flow back into the raw pulp storage chamber. The ultrasonic transducer 19 generates high-frequency acoustic vibrations, destroys the surface of the solution to generate oscillation waves, thereby generating aerosols on the surface of the solution. The aerosols after ultrasonic atomization are preliminarily mixed with the atomized droplets generated by the micro jets in the primary mixing chamber 6, and then collected in the mixed flow conduit 10. The mixed flow conduit 10 is simultaneously connected to the air outlet of the primary mixing chamber 6 of the dual-channel blower 7. Driven by the airflow, the mixed flow is gathered in the mixing microchannel 21 in the mixing cooler 11 for further mixing. The temperature in the mixing microchannel 21 is adjusted by controlling the patch semiconductor cooling sheet 22 through the adaptive cooling power supply 23, so that the mist homogenized stock liquid in it is quickly cooled and liquefied to form a homogenized stock liquid for special dietary drinks, and is properly collected in the liquid collecting tank 12. Through two times of mixing and homogenization, the homogenization pressure can be guaranteed at the same time, and a better particle size distribution effect can be produced. At the same time, it can also overcome the problem that the conventional microjet flow rate is small and ultrasonic atomization is difficult to control the mixing of different atomized droplets.
