Description

Technical Field

[0001] The invention relates to the technical field of beverage mixing and homogenizing, and in particular discloses a beverage homogenizing feeding device. Background Art

[0002] The beverage homogenizing feeding device is one of the key equipment in the beverage production process. Its main function is to homogenize the fruit and vegetable beverages, so as to ensure that the fruit and vegetable beverages have uniform particle size and composition before entering the packaging, improve product quality, prevent stratification caused by the precipitation of fruit and vegetable particles, and maintain the stability and transparency of fruit and vegetable beverages.

[0003] Chinese patent CN118767767A discloses a homogenous feeding device for fruit and vegetable drinks. By setting up multiple stirring rods and a gushing unit to prevent precipitated particles from appearing at the bottom of the tank, the uniformity of beverage feeding is improved, and the problem of poor mixing effect and uneven distribution of particles in the beverage when a single stirring rod is set is solved.

[0004] In order to distribute the particles in the beverage more quickly and evenly in the beverage, the above-mentioned device needs to rotate multiple stirring rods at high speed and apply a large shear force to the beverage. The strong shear force will destroy the original existence state of some flavor substances in the beverage. In fruit juice beverages containing pulp particles and flavor oil droplets, the shear force generated by the high-speed rotating stirring rod may destroy the emulsified structure that wraps the flavor oil droplets. Once these oil droplets are destroyed, the volatile flavor components therein are easily evaporated and lost. Taking strawberry juice beverage as an example, the fruity aroma of strawberry comes from some esters and terpene compounds. Under the action of the shear force of the stirring rod, the wrapping structure of these compounds is destroyed, and the aroma components are volatilized, resulting in damage to the flavor. If the rotation speed of the stirring rod is reduced, although it can reduce some of the flavor loss of the beverage, it will take a longer time to mix and homogenize the beverage under low rotation speed conditions, resulting in reduced efficiency of homogenous mixing. Summary of the invention

[0005] In view of the above deficiencies in the prior art, the present invention provides a beverage homogenizing feeding device to solve the problem in the prior art that the emulsified structure encapsulating the flavor oil droplets of fruit juice drinks containing pulp particles and flavor oil droplets is easily destroyed under the shear force generated by the high-speed rotating stirring rod, resulting in the volatilization and loss of volatile flavor components therein; if the rotation speed of the stirring rod is reduced, although the partial flavor loss of the beverage can be reduced, the efficiency of homogenizing mixing will be reduced.

[0016] The beneficial effects of the present invention are: 1. The present invention is provided with a stirring assembly in the barrel. The stirring assembly rotates at a low speed in the barrel to preliminarily disperse and mix the particles in the beverage, so that these ingredients are preliminarily evenly distributed in the beverage to prevent agglomeration, and the damage to heat-sensitive and volatile flavor substances is small, which is helpful to protect the natural flavor of the raw materials; then, a part of the beverage is homogenized by a split-flow refinement homogenization unit, and the beverage enters the incident homogenization part through two split-flow shear tubes and converges, and impact homogenization and shear homogenization are generated between them. In this process, the energy transfer is more uniformly dispersed. Under the mild energy transfer environment of split-flow homogenization, the flavor substances in the beverage are not easy to chemically bond due to excessive local energy as in the traditional homogenization method. The breakage or structural change of the beverage is reduced, thereby reducing the destruction of flavor substances; the part of the beverage after homogenization and the other part of the beverage discharged from the cylinder are combined in the Venturi mixing section, and the part of the beverage treated by the diversion and refinement homogenization unit and the part of the beverage not treated by the diversion and refinement homogenization unit are combined in the throat of the Venturi mixing section. Due to the special structure of the throat of the Venturi mixing section, the fluid flow rate is accelerated and the pressure is reduced, and the two fluids can be quickly and fully mixed. This mixing method is more efficient than the ordinary mixing method, and can make the fine part after diversion and homogenization quickly diffuse into the whole beverage. On the basis of retaining the flavor of the beverage to the greatest extent, it can also further improve the overall efficiency of homogenization mixing.

[0017] 2. The present invention drives the hollow extraction tube and the drainage blade to rotate through the motor 2. The drainage blade cooperates with the stirring blade 1 to realize radial circulation of the beverage in the cylinder, thereby improving the homogenization and mixing efficiency of the beverage. At the same time, the rotation of the drainage blade causes the beverage and particles at the bottom of the cylinder cavity to flow radially upward. In combination with a plurality of drainage hoods 2 with different heights and the hollow extraction tube, the beverage and particles at different liquid levels in the cylinder can be transported into the diversion, refinement and homogenization unit. Each component of the beverage can be properly diverted, refined and homogenized. The higher liquid level part may contain more volatile flavor components, and the lower liquid level part may contain more solid particles. After being diverted, refined and homogenized respectively, and then merged through the Venturi mixing part, the entire beverage can reach a more uniform state at the microscopic level, and both the distribution of flavor substances and the degree of particle refinement are more consistent.

[0018] 3. The present invention is provided with a particle dispersion unit. When the stirring shaft rotates and drives the rotating rod to rotate, the inclined top block at the bottom of the rotating rod moves out of the inclined groove, and the inclined top block pushes the rotating rod to rise. When the inclined top block enters the inclined groove again, the spring pushes the rotating rod to descend and contacts with the inner plate to generate vibration. The vibration can break the viscous resistance and surface tension inside the liquid, so that the various ingredients in the beverage can be mixed more quickly. Adding vibration on the basis of stirring can produce a stronger convection effect. The vibration can cause the fluid to produce complex turbulence phenomena in the Venturi mixing section, reduce the viscosity of the liquid in the Venturi mixing section, improve its fluidity, and prevent the liquid from flowing poorly or being blocked due to local pressure changes. The tiny disturbance force generated by the vibration can interrupt this agglomeration trend, ensure that the particles remain dispersed, and prevent the particles from gathering again inside the Venturi mixing section.

Both sides of the outer surface of the throat end of the venturi mixing section 4 are penetrated by connecting pipes 56, and the end of the output pipe 55 away from the incident homogenizing section 54 is connected to the connecting pipe 56. The inner pipe of the rotating joint 51 penetrates the lower end of the cylinder 1 and extends to the inside of the cylinder 1. The pump body 52 is used to pump the liquid in the cylinder 1 into the flow dividing and shearing tubes 53, and the liquid in the flow dividing and shearing tubes 53 is impact homogenized and shear homogenized in the incident homogenizing section 54.

[0023] The stirring assembly includes a stirring shaft 12 located inside the cylinder 1, a plurality of stirring blades 13 fixedly connected to the outer surface of the stirring shaft 12, and a mixing rod 14. The upper end of the stirring shaft 12 is rotatably connected to the lower end of the cover 2, and the lower end of the stirring shaft 12 is rotatably connected to the inside of the cylinder 1. A motor 3 is fixedly connected to the middle of the upper end of the cover 2, and the output end of the motor 3 passes through the upper end of the stirring shaft 12 fixed to the cover 2.

[0024] A drainage cover 11 is fixedly connected to the middle of the inner bottom wall of the cylinder 1, and the drainage cover 11 is sleeved on the outside of the stirring blade 13. The lower end of the cover 2 is fixedly connected with a drainage plate 22 for guiding the material entering the cylinder 1 from the feed port 21 to flow toward the outer wall of the stirring shaft 12. The stirring blade 13 drives the material to form a circular flow in the drainage cover 11, and the drainage cover 11 guides the material to flow toward the mixing rod 14 and is further stirred by the mixing rod 14.

[0025] By adopting the above technical solution, the beverage enters the barrel 1 from the feed inlet 21, and after entering from the feed inlet 21, it first flows to the guide plate 22, which is in the shape of an inverted truncated cone. The guide plate 22 drives the beverage to flow toward the stirring shaft 12, and the motor 3 is started to drive the stirring shaft 12 to rotate at a low speed. The rotation of the stirring shaft 12 drives the plurality of stirring blades 13 and the plurality of mixing rods 14 to rotate, and the plurality of stirring blades 13 drive the material to form a circular flow in the guide cover 11, and the guide cover 11 guides the material to flow toward the mixing rod 14 and is mixed by the mixing rod 14. Further stirring, the particles in the drink are initially dispersed and mixed by the stirring assembly rotating at a low speed in the barrel 1, so that these ingredients are initially evenly distributed in the drink to prevent agglomeration, and the damage to heat-sensitive and volatile flavor substances is relatively small, which helps to protect the natural flavor of the raw materials; after being stirred and mixed by the mixing rod 14, a part of the drink is directly discharged from the discharge port 15 and enters the venturi mixing part 4, and the other part of the drink enters the inner tube of the rotary joint 51, and the pump body 52 extracts the other part of the drink in the rotary joint 51 and pumps it into the diversion shear tube 53, The beverages in the two adjacent split shear tubes 53 enter the incident homogenizing section 54 and merge to produce collision and shearing, so as to achieve homogenous mixing of the liquid. In this process, the energy transfer is more evenly dispersed. Under the mild energy transfer environment of the split homogenizing, the flavor substances in the beverage are not likely to break chemical bonds or change structures due to excessive local energy as in the traditional homogenizing method, thereby reducing the destruction of the flavor substances. The liquid discharged from the incident homogenizing section 54 enters the Venturi mixing section 4 through the output pipe 55 and the connecting pipe 56, and is mixed with the liquid discharged from the discharge port 15. The discharged parts of the beverage merge; when the part of the beverage processed by the diversion and refinement homogenization unit 5 merges with the part of the beverage not processed by the diversion and refinement homogenization unit 5 at the throat of the venturi mixing section 4, the special structure of the throat of the venturi mixing section 4 accelerates the flow rate of the fluid and reduces the pressure, and the two fluids can be quickly and fully mixed. This mixing method is more efficient than the ordinary mixing method, and can make the fine part that has been diverted and homogenized quickly diffuse into the entire beverage. On the basis of retaining the flavor of the beverage to the greatest extent, it can also further improve the overall efficiency of homogenization mixing.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, the cylinder 1 is also connected to an inner circulation radial flow unit 7, which includes a plurality of drainage covers 72 of different heights fixedly connected to the inner bottom wall of the cylinder 1 at intervals and a plurality of hollow extraction pipes 73 of different heights respectively located inside the drainage cover 72, the upper end of the hollow extraction pipe 73 is rotatably connected to the inner wall of the drainage cover 72, and the lower end of the hollow extraction pipe 73 is fixedly connected to the inner pipe of the rotary joint 51. The plurality of hollow extraction pipes 73 of different heights are used to discharge materials at different liquid levels inside the cylinder 1 into the plurality of rotary joints 51 respectively.

[0027] A plurality of drainage blades 74 are fixedly connected to the top of the outer surface of the hollow extraction pipe 73, and the drainage blades 74 are located inside the drainage cover 2 72. The plurality of drainage blades 74 drive the material to form a circular flow in the drainage cover 2 72, and the drainage cover 2 72 drives the material at the bottom of the cylinder 1 to flow upward.

[0028] The bottom of the cylinder 1 is rotatably connected to a plurality of gears 75, and the outer surfaces of the plurality of gears 75 are meshed with toothed disks 76. The plurality of gears 75 are respectively fixedly sleeved on the outside of the inner tubes of the plurality of rotary joints 51. The bottom of the cylinder 1 is also rotatably connected to a gear 2 meshed with toothed disk 76. The lower end of the cylinder 1 is fixedly connected to a motor 2 71 in cooperation with the gear 2. The output end of the motor 2 71 passes through the cylinder 1 and is fixedly connected to the lower end of the gear 2.

[0029] By adopting the above technical solution, the motor 2 71 can drive the gear 2 to rotate inside the cylinder 1, and the rotation of the gear 2 drives the toothed disc 1 76 to rotate, thereby driving the gear 1 75 to rotate, and the rotation of the gear 1 75 drives the inner tube of the rotary joint 51 and the hollow extraction tube 73 to rotate, and the rotation of the hollow extraction tube 73 drives the drainage blade 74 to rotate, and the drainage blade 74 drives the material to form a circular flow in the drainage cover 2 72, and the drainage cover 2 72 drives the material at the bottom of the cylinder 1 to flow upward, the stirring blade 13 drives the central liquid in the cylinder 1 to flow downward, and the drainage blade 74 drives the liquid at the bottom of the inner cavity of the cylinder 1 to flow upward, so that the beverage is stirred in the cylinder. A radial circulation flow is realized in the cylinder 1 to improve the homogenization and mixing efficiency of the beverage; starting the pump body 52 can pump the beverage and particles at different liquid levels in the cylinder 1 into the diversion, refinement and homogenization unit 5 through a number of hollow extraction tubes 73 with different heights, and each component of the beverage can be properly diverted, refined and homogenized. The higher liquid level part may contain more volatile flavor components, and the lower liquid level part may contain more solid particles. After being diverted, refined and homogenized respectively, and then merged through the Venturi mixing section 4, the entire beverage can reach a more uniform state at the microscopic level, and both the distribution of flavor substances and the degree of particle refinement are more consistent.

[0030] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, a movable groove 121 is provided inside the stirring shaft 12, and a particle dispersion unit 8 is arranged inside the venturi mixing section 4. The particle dispersion unit 8 includes an inner plate 84 fixedly connected to the bottom of the inner wall of the diffusion end of the venturi mixing section 4, a positioning rod 87 with one end fixedly connected to the inner wall of the movable groove 121 and the other end fixedly connected to the upper end of the inner plate 84, a rotating rod 81 movably sleeved on the outside of the positioning rod 87 and the upper end of which is inserted into the movable groove 121, and a plurality of stirring blades 83 fixedly connected to the outer surface of the rotating rod 81.

[0031] The positioning rod 87 is sleeved with a spring 82 on the outside, and the spring 82 is located inside the movable groove 121. The two ends of the spring 82 are respectively fixed to the inner wall of the movable groove 121 and the upper end of the rotating rod 81. The lower end of the rotating rod 81 is integrally formed with a plurality of inclined ejector blocks 85, and the upper end of the inner plate 84 is cooperated with to open a plurality of inclined grooves 86 for accommodating the inclined ejector blocks 85.

[0032] By adopting the above technical solution, when the stirring shaft 12 rotates to drive the rotating rod 81 to rotate, the inclined top block 85 at the bottom of the rotating rod 81 moves out of the inclined groove 86, and the inclined top block 85 pushes the rotating rod 81 to rise. When the inclined top block 85 moves into the inclined groove 86 again, the spring 82 pushes the rotating rod 81 to descend, contact with the inner plate 84 and generate vibration. The vibration can break the viscous resistance and surface tension of the liquid inside the Venturi mixing section 4, so that the various ingredients in the beverage can be mixed more quickly. Adding vibration on the basis of stirring can produce a stronger convection effect. The vibration can cause the fluid to produce complex turbulence in the Venturi mixing section 4, reduce the viscosity of the liquid in the Venturi mixing section 4, improve its fluidity, and prevent the liquid from flowing poorly or being blocked due to local pressure changes. The small disturbance force generated by the vibration can interrupt this agglomeration trend, ensure that the particles remain dispersed, and prevent the particles from gathering again inside the Venturi mixing section 4.

[0033] like Figure 9-12 As shown, a stirring cooperation unit 9 is also provided inside the Venturi mixing section 4, and the stirring cooperation unit 9 includes an active groove 2 41 opened inside the diffusion end of the Venturi mixing section 4 and an active groove 3 42 connected to the active groove 2 41, a gear 5 95 rotatably connected inside the active groove 2 41, a toothed disc 2 96 rotatably connected inside the active groove 3 42 and meshing with the gear 5 95, a connecting sleeve 97 fixed to the outer side of the toothed disc 2 96 and rotatably connected to the active groove 3 42, a gear 4 94 fixed to the connecting sleeve 97 and rotatably connected to the lower end of the Venturi mixing section 4, a rotating ring 98 rotatably connected to the inner wall of the diffusion end of the Venturi mixing section 4, and an interfering flow paddle 99 fixed to the inner wall of the rotating ring 98, the outer surface of the rotating ring 98 is provided with a tooth key meshing with the gear 5 95, and the bottom of the outer surface of the Venturi mixing section 4 is matched with and fixed with a driving part for driving the gear 4 94 to rotate.

[0034] The driving part includes a motor 3 91 fixedly connected to the bottom of the outer surface of the venturi mixing part 4, a support plate 92 fixedly connected to the lower end of the venturi mixing part 4, a gear 3 93 rotatably connected to the upper end of the support plate 92 and meshing with a gear 4 94, and the output end of the motor 3 91 is fixedly connected to the gear 3 93.

[0035] By adopting the above technical solution, when the starting motor 3 91 drives the gear 3 93 to rotate, the gear 3 93 rotates and drives the gear 4 94 to rotate. The gear 4 94 rotates and drives the toothed disc 2 96 to rotate through the connecting sleeve 97. The toothed disc 2 96 rotates and drives the rotating ring 98 to rotate through the gear 5 95. The rotating ring 98 rotates and drives the spoiler paddle 99 to rotate. The rotation direction of the spoiler paddle 99 is opposite to the rotation direction of the rotating rod 81. The stirring blade 2 83 on the rotating rod 81 pushes the fluid in the feed end of the Venturi mixing section 4 toward the throat and the diffusion end. The spoiler paddle 99 rotates inside the diffusion end to produce a reverse The force in two directions can make the fluid mix more fully under the force in two directions. This two-way stirring can form a more complex fluid movement form in the Venturi mixing section 4, including convection, vortex and other mixing methods. For tiny particles in the beverage, such as additive particles, tiny pulp particles after homogenization, etc., the counter-rotating spoiler paddles 99 can make them collide and mix with each other in different flow directions, further refine the particle distribution, and make the beverage more uniform in microstructure, which is very important for improving the delicate taste of the beverage and maintaining the stability of the tiny particles in the beverage.

[0036] Working principle and process: The beverage enters the cylinder 1 from the feed port 21, and the motor 3 is started to drive the stirring shaft 12 to rotate at a low speed. The stirring shaft 12 rotates to drive the plurality of stirring blades 13 and the plurality of mixing rods 14 to rotate. The plurality of stirring blades 13 drive the material to form a circular flow in the drainage cover 11, and the drainage cover 11 guides the material to flow toward the mixing rod 14 and is further stirred by the mixing rod 14. After being stirred and mixed by the mixing rod 14, a part of the beverage is directly discharged from the discharge port 15 and enters the venturi mixing part 4, and the other part The divided beverages enter the inner tube of the rotary joint 51, and the pump body 52 is started to pump beverages and particles at different liquid levels in the cylinder 1 into the diverter shear tube 53 through a number of hollow pumping tubes 73 with different heights. The beverages in two adjacent diverter shear tubes 53 merge in the incident homogenizing section 54 and produce collision and shearing, thereby achieving homogeneous mixing of the liquid. The liquid discharged from the incident homogenizing section 54 enters the Venturi mixing section 4 through the output pipe 55 and the connecting pipe 56 and merges with part of the beverage discharged from the discharge port 15.
