DETAILED DESCRIPTION

[0016] 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.

[0017] Example 1: See Figure 1 , a preparation process of a mineral oral liquid, comprising the following steps: S1, prepare raw materials and pour purified water into preparation tank 1; S2, heating the purified water to boil, and then pouring the raw materials into the discharge unit 2 in the preparation tank 1 for uniform discharge; S3, using the stirring unit 29 in the preparation tank 1 to stir the purified water added with the raw materials, so that the raw materials and the purified water are mixed and dissolved; S4, filtering the dissolved stock solution through a 15 μm titanium rod for the first time; S5. Add an acidity regulator to the stock solution so that the pH value of the stock solution after the initial filtration is between 3.0 and 6.0; S6, filtering the pH-adjusted stock solution for a second time using a 5 μm titanium rod and a 0.22 μm folded membrane; S7. Fill and seal the product, sterilize at 110°C for 50 minutes, then inspect by light and package.

[0018] In this scheme, the raw materials are: 1%-3% calcium citrate, 0.5%-1.5% magnesium gluconate, 0.01%-0.02% zinc gluconate, 5%-20% sugar alcohol, 0.01%-0.1% acidity regulator, 0.1%-5% colloid, 0.01%-0.03% flavoring agent, 0.5%-1% edible flavor; Calcium citrate, magnesium gluconate, zinc gluconate and sugar alcohol powder are poured into the discharge unit 2 as raw material powders in step S2, and colloids, flavoring agents and edible flavors are added in step S5. After addition, the pH value of the stock solution is adjusted by an acidity regulator.

[0019] The top of the preparation tank 1 in this solution is provided with a water inlet for the entry of purified water, and the bottom is provided with a discharge port for the discharge of the mixed stock solution. A heating layer is provided on the outside of the preparation tank 1 to heat the internal liquid.

[0020] For further information, see Figure 2 - Figure 4 and Figure 8 The discharge unit 2 shown in the figure includes a feed hopper 3, a through hole matching the feed port is opened on the tank cover of the preparation tank 1, the feed hopper 3 is fixed to the inner wall of the preparation tank 1 through a bracket, a discharge pipe 4 is rotatably installed at the bottom end of the feed hopper 3, a discharge assembly 5 is installed in the discharge pipe 4, and a rotating assembly 6 for driving the discharge pipe 4 to rotate is installed on the feed hopper 3; Among them, the discharge component 5 includes a rotating rod 7 rotatably docked with the discharge pipe 4, a support frame 8 is fixed on the discharge pipe 4, a discharge motor 9 is fixed on the support frame 8, the output end of the discharge motor 9 is fixed with a universal joint through a coupling, and is fixed to the outer end of the rotating rod 7 through the universal joint, a spiral blade 10 is fixed to the outer side of the rotating rod 7, a discharge hole 11 is opened at the bottom of the discharge pipe 4, a mixing component 12 is installed at the bottom of the support frame 8, and the mixing component 12 is used to assist the raw materials on the liquid surface to mix with the original liquid.

[0021] In this solution, the process of evenly discharging raw material powder is achieved: First, personnel pour raw material powder into the feed hopper 3, and under the action of gravity, the raw material will enter the discharge pipe 4; Afterwards, the discharge motor 9 drives the spiral blade 10 to start rotating, moving the powder entering the discharge pipe 4 and discharging it through a plurality of discharge holes 11; At the same time, the rotating assembly 6 operates, driving the discharge pipe 4 to rotate in the preparation tank 1, so that the discharged raw material powder is laid along the preparation tank 1, thereby achieving uniform discharge of the raw material powder.

[0022] It should also be noted that the discharge pipe 4 is in the shape of an L-shaped pipe, and its bottom is in an inclined state, which is convenient for the discharge of the separation in the discharge pipe 4.

[0023] For further information, see Figure 6 - Fig. 9The mixing assembly 12 includes a mixing rod 13 rotatably connected to the bottom of the support frame 8, a mixing tube 14 is fixed to the outer side of the bottom of the support frame 8, one end of the mixing rod 13 is rotatably connected to the outer end of the mixing tube 14, and a linkage gear 15 is fixed to the other end of the mixing rod 13 and the output end of the discharge motor 9. The outer sides of the two linkage gears 15 are meshed with a toothed belt 16, an agitator 17 is fixed to the outer end of the mixing rod 13, and a liquid transfer member 18 is installed at the outer end of the mixing tube 14; The agitator 17 includes an agitator frame 19 fixed to the mixing rod 13 , and an agitator plate 20 is fixed in the agitator frame 19 . The agitator plate 20 is tilted and rotates to drive the liquid in the preparation tank 1 to flow toward the center of the preparation tank 1 .

[0024] The method for dissolving the powder floating on the liquid surface into the original liquid is as follows: first, the mixing rod 13 is rotated by utilizing the action of two interlocking gears 15 and the toothed belt 16, thereby driving the stirring frame 19 to rotate synchronously. A stirring plate 20 is fixed in the stirring frame 19. Each time the stirring plate 20 rotates from above the liquid surface to the liquid surface, the floating powder is driven to move toward the liquid surface, thereby destroying the agglomeration state of the floating powder, thereby improving the dissolution efficiency between the powder and the original liquid.

[0025] It should also be noted that the stirring plate 20 is tilted so that when the stirring plate 20 rotates along the mixing rod 13 following the stirring frame 19, it can drive the stock solution to flow into the preparation tank 1, thereby achieving a certain turbulent effect and facilitating the mixing of the powder and the stock solution.

[0026] In this solution, the rotating assembly 6 includes a rotating motor 26. A recess is opened in the feed hopper 3. The rotating motor 26 is fixed in the recess. A transmission gear 27 is fixed to the top of the discharge pipe 4. The output end of the rotating motor 26 is fixed with a driving gear 28 meshing with the transmission gear 27 through a coupling. The rotating motor 26 drives the driving gear 28 to rotate, so that the transmission gear 27 follows the rotation and drives the discharge pipe 4 to rotate accordingly, thereby achieving uniform laying of powder.

[0027] For further information, see Figure 3 - Figure 6 The stirring unit 29 includes a stirring rod 30, the bottom of which is rotatably mounted with a support plate fixed to the bottom of the preparation tank 1, the top of the stirring rod 30 is fixed to the bottom of the discharge pipe 4, and a stirring blade 31 is fixed to the outside of the stirring rod 30. The rotation of the discharge pipe 4 drives the stirring rod 30 to rotate synchronously, so that the stirring blade 31 can rotate in the preparation tank 1, disturb the liquid in the preparation tank 1, and improve the dissolution efficiency of the powder.

[0028] It should be noted that when preparing the mineral oral liquid, the raw materials are first prepared according to the ratio, and then a specified amount of purified water is injected into the preparation tank 1. After the purified water is injected, the liquid level just submerges the mixing tube 14, and then the raw material powder is poured in. Through the cooperation of the discharge component 5 in the discharge pipe 4 and the rotating component 6, the material is scattered while rotating. Compared with the traditional one-time pouring method, the feeding method in this scheme can make the powder more evenly distributed on the liquid surface, which is convenient for the subsequent contact and mixing of the powder and the stock solution. Then, through the joint action of the mixing component 12 and the stirring unit 29, the powder and the stock solution are quickly mixed and dissolved, avoiding the occurrence of lumps of the stock solution floating on the liquid surface.

[0029] In this scheme, in order to improve the micronization and homogenization of the dispersed matter in the mixed solution during the preparation of the mineral oral liquid, this scheme adopts a homogenization emulsification process for the mixed solution, using existing emulsification equipment such as a homogenizer to make the solution rotate at high speed or at high pressure to achieve homogenization and emulsification, thereby increasing the absorption rate of the substances in the solution, making the solution more stable, and also improving the taste of the product to meet the public's drinking habits.

[0030] It should also be noted that the equipment designed in this scheme can also be used in the preparation of substances such as "lutein ester, AA oil, conjugated linoleic acid, astaxanthin, zeaxanthin, carotene, fish oil, krill oil, and Haematococcus pluvialis".

[0031] Example 2: Please refer to Fig. 9 and Fig.10 This embodiment further explains the first embodiment, and the difference lies in the development of one specific implementation of the liquid transfer member 18.

[0032] Specifically, the liquid transfer member 18 includes a liquid outlet pipe 21 and a liquid suction pipe 22, the liquid outlet pipe 21 and the liquid suction pipe 22 are fixedly connected to the outer end of the mixing tube 14, a one-way valve for discharging the liquid in the mixing tube 14 outward is installed in the liquid outlet pipe 21, a one-way valve for discharging the original liquid into the mixing tube 14 is installed in the liquid suction pipe 22, an extension pipe 23 that fits the mixing tube 14 is fixed to the outer end of the liquid suction pipe 22, a reciprocating thread groove is engraved on the outer side of the mixing tube 14, a piston plate 24 is threadedly sleeved on the outer side of the mixing rod 13, and a slide bar 25 that slides and fits the piston plate 24 is fixed in the mixing tube 14; In this solution, when the mixing rod 13 rotates, the piston plate 24 is driven to reciprocate in the mixing tube 14. When the piston plate 24 moves toward the support frame 8, the piston plate 24 begins to absorb liquid, and the liquid near the middle is sucked into the mixing tube 14 through the liquid suction tube 22 and the extension tube 23. Then, when the piston plate 24 moves outward, the liquid in the mixing tube 14 is discharged outward through the liquid outlet pipe 21. At this time, the liquid in the middle area of ​​the preparation tank 1 is sucked and discharged toward the periphery, thereby increasing the flow effect of the liquid and avoiding the accumulation of liquid dissolved in the middle powder. It should also be noted that the stirring frame 19 is designed not to touch the liquid outlet tube 21 , the liquid pipette 22 and the extension tube 23 when rotating normally.

[0033] Example 3: Please refer to Figure 3 - Figure 6 This embodiment further explains other embodiments, and the difference lies in that some characteristic structures of the stirring unit 29 are optimized to facilitate the flow of liquid in the preparation tank 1.

[0034] Specifically, the stirring blade 31 is in a spiral shape. When the stirring blade 31 rotates, the liquid at the bottom of the preparation tank 1 can be guided upward. A connecting plate 32 is fixed to the outer side of the stirring rod 30, and an arc plate 33 is fixed to the outer end of the connecting plate 32. Figure 4 As shown, when the arc-shaped plate 33 rotates with the stirring rod 30, it can drive the liquid on the periphery of the preparation tank 1 to flow toward the center; In this scheme, it is mainly used to guide the liquid at the bottom of the preparation tank 1 upward, and to make the liquid on the periphery of the preparation tank 1 flow toward the center, and then cooperate with the suction tube 22 and the extension tube 23 to suck the liquid near the middle into the mixing tube 14, and then when the piston plate 24 moves outward, the liquid in the mixing tube 14 is discharged outward through the liquid outlet pipe 21, thereby realizing a circular flow direction of the liquid in the preparation tank 1, so that the liquid in the preparation tank 1 can be evenly contacted and mixed with the raw material powder, so that the dissolution efficiency with the raw material powder is higher.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
