Description

Technical Field

[0001] This utility model relates to the field of rice milk production technology, specifically to a homogenizer for producing natural rice milk. Background Technology

[0002] Homogenizers are widely used in the food, pharmaceutical, chemical, and cosmetic industries, primarily to refine and homogenize particles in liquids, emulsions, or suspensions, thereby improving product stability and quality. Their working principle involves the shearing, collision, and cavitation effects generated when high-pressure material flows through the narrow gap between the valve core and valve seat, achieving material homogenization. Existing homogenizers only have one homogenizing valve, limiting their effectiveness in handling high-viscosity, multiphase mixtures. The material is not sufficiently dispersed before entering the homogenizing gap, affecting the final homogenization efficiency and particle refinement. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a homogenizer for producing natural rice milk, which features multi-stage homogenizing valves and a mixing mechanism to promote material mixing and improve homogenization results.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides a homogenizer for producing natural rice milk, comprising:

[0005] A feed pipe, on which a one-way valve is installed;

[0006] A plunger pump, wherein the feed end of the plunger pump is connected to a feed pipe;

[0007] A multi-stage homogenizing valve, wherein the inlet end of the multi-stage homogenizing valve is connected to the outlet end of the plunger pump;

[0008] The multi-stage homogenizing valve includes a valve body, a primary valve core, and a secondary valve core. A mixing mechanism is provided in the valve body between the primary and secondary valve cores. The material enters from the feed end of the multi-stage homogenizing valve and passes through the primary valve core, the mixing mechanism, and the secondary valve core in sequence before being discharged from the discharge end.

[0009] Preferably, the mixing mechanism includes:

[0010] The mixing channel, located within the valve body, connects the discharge end of the primary valve core with the inlet end of the secondary valve core.

[0011] Multiple mixing units are distributed sequentially within the mixing channel to drive the material to repeatedly change between flowing towards the inner wall of the mixing channel and flowing towards the axis of the mixing channel.

[0012] Preferably, the mixing unit comprises:

[0013] A dispersing cone is disposed within a mixing channel, with its tip facing the feeding direction;

[0014] A converging ring is disposed in the mixing channel at the rear end of the dispersing cone. The converging ring has a funnel-shaped through hole at its center, with the smaller diameter end of the through hole facing the discharge direction.

[0015] Preferably, the dispersing cone is fixed to the ring body by a connecting plate, and the ring body and the converging ring are staggered in the mixing channel.

[0016] Preferably, the valve body has a first mounting cavity for installing a primary valve core and a second mounting cavity for installing a secondary valve core. The primary valve core includes an adjusting rod, which is threaded onto the valve body. A plug is provided at one end of the adjusting rod located in the first mounting cavity, and the diameter of the plug is larger than the diameter of the feed end of the first mounting cavity.

[0017] Preferably, the first mounting cavity has a mounting hole at the end away from the plug, and a fixing cylinder is sealed and installed in the mounting hole, with the adjusting rod threaded onto the fixing cylinder.

[0018] Preferably, a guide sleeve is fixed at one end of the plug near the adjusting rod, and the adjusting rod is movably inserted into the guide sleeve.

[0019] Preferably, the adjusting rod between the guide sleeve and the fixed cylinder is stepped and fitted with a disc spring.

[0020] Preferably, a wear-resistant disc is provided at the end of the plug away from the adjusting rod.

[0021] Preferably, the end of the plug near the wear-resistant disc is tapered, and the wear-resistant disc has a tapered groove that mates with the plug.

[0022] The beneficial effects of this utility model are as follows:

[0023] This invention features a one-way valve on the feed pipe that draws in material during the return stroke of the plunger pump, while preventing material from returning to the feed pipe during the push stroke, thus ensuring unidirectional flow and preventing the pump from running dry. The multi-stage homogenizing valve employs a structure of a primary valve core, a mixing mechanism, and a secondary valve core. Material passes through these three parts sequentially, achieving graded homogenization. The primary valve core initially processes the material, the mixing mechanism further mixes it, and the secondary valve core performs deep homogenization. This graded processing effectively breaks down material particles, resulting in a more uniform particle size distribution in the natural rice milk, a smoother texture, and improved product quality. Multiple mixing units are distributed within the mixing channel, driving the material to repeatedly change between flowing towards the inner wall of the mixing channel and flowing towards the axis of the mixing channel. This generates high-frequency shearing, collision, and turbulence, enhancing the mixing effect and resulting in a more uniform dispersion of the components in the natural rice milk.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] like Figures 1 to 6 As shown in the figure, Embodiment 1 of this utility model provides a homogenizer for producing natural rice milk, including a feed pipe 1, a plunger pump 2, and a multi-stage homogenizing valve 3. A hopper is provided at the top of the feed pipe 1, and the feed pipe 1 is connected to the feed inlet of the plunger pump 2. A one-way valve is installed on the feed pipe 1. The one-way valve opens during the return stroke of the plunger pump 2, drawing material from the feed pipe 1 into the pump. When the plunger pump 2 is in its pushing stroke, the one-way valve automatically closes due to spring force, effectively preventing material from flowing back into the feed pipe 1, avoiding wear caused by the plunger pump 2 running dry, and ensuring continuous feeding. The discharge end of the plunger pump 2 is connected to the feed end of the multi-stage homogenizing valve 3. The reciprocating motion of the plunger pressurizes and transports the rice milk slurry to the multi-stage homogenizing valve 3.

[0036] like Figure 4 and Figure 5 As shown, the multi-stage homogenizing valve 3 includes a valve body 4, a primary valve core 5, and a secondary valve core 6. The primary valve core 5 and the secondary valve core 6 have the same basic structure. The valve body 4 has a first mounting cavity 11 and a second mounting cavity 12, which are used to install the primary valve core 5 and the secondary valve core 6, respectively. A mixing mechanism is provided in the valve body 4 between the primary valve core 5 and the secondary valve core 6. The discharge end of the primary valve core 5 is located on the side wall of the first mounting cavity 11 and can be connected to the inlet end of the second mounting cavity 12 through the mixing channel 7. Four mixing units are distributed sequentially along the material flow direction in the mixing channel 7. Each mixing unit includes a dispersing cone 8 and a converging ring 9.

[0037] like Figure 5 and Figure 6 As shown, the dispersing cone 8 is conical in shape and fixed to the inner side of the ring 10 by three connecting plates. The tip of the dispersing cone 8 faces the feeding direction, diffusing the material, which has been initially homogenized by the first-stage valve core 5, towards the inner wall of the mixing channel 7. The converging ring 9 is fixed behind the dispersing cone 8, with a funnel-shaped through hole in the center. The end of the through hole with a smaller diameter faces the discharge direction, forcing the diffused material to converge towards the channel axis. The material undergoes periodic "dispersion-convergence" disturbances in the mixing channel 7, generating turbulence and achieving uniform mixing of the material.

[0038] During operation, the rice milk slurry enters the plunger pump 2 through the feed pipe 1 via a one-way valve. After being pressurized, it sequentially passes through the primary valve core 5 for initial crushing, the mixing mechanism for dynamic mixing, and the secondary valve core 6 for deep homogenization. The primary valve core 5 applies initial pressure shearing to the material, while the mixing mechanism forces the material to repeatedly change its flow direction through its flow channel structure, enhancing particle collision and dispersion. The secondary valve core 6 further refines the particles, and finally, uniformly sized rice milk is discharged from the outlet, significantly improving the product's fineness and stability.

[0039] Example 2:

[0040] Based on Embodiment 1, this embodiment provides a detailed description of the specific structures of the primary valve core 5 and the secondary valve core 6. Since the primary valve core 5 and the secondary valve core 6 have the same basic structure but different positions, the specific structure of the primary valve core 5 will be explained using it as an example.

[0041] like Figure 4 and Figure 5 As shown, the primary valve core 5 includes an adjusting rod 13 and a plug 14. A mounting hole is provided at the end of the first mounting cavity 11 furthest from the plug 14. A fixed cylinder 15 is threaded into the mounting hole, and a sealing ring is provided between the outer wall of the fixed cylinder 15 and the inner wall of the mounting hole. The adjusting rod 13 passes through the fixed cylinder 15 and is threaded into it. A sealing ring is also provided between the outer wall of the adjusting rod 13 and the inner wall of the fixed cylinder 15. The plug 14 is located at the end of the adjusting rod 13 within the first mounting cavity 11. Because the diameter of the plug 14 is larger than the diameter of the feed end of the first mounting cavity 11, when high-pressure material enters from the feed end of the first mounting cavity 11, due to the small gap between the plug 14 and the feed end, the material forms a high-speed jet as it passes through the gap. Through instantaneous pressure changes and intense shearing and impact, the particles in the material are refined and uniformly mixed.

[0042] The gap between the plug 14 and the feed end can be changed by rotating the adjusting rod 13, thereby achieving stepless adjustment of the homogenization pressure. For example, when processing brown rice slurry, the gap can be increased to reduce the initial pressure and avoid overload; when processing polished rice slurry, the gap can be reduced to increase the pressure and ensure the refining effect.

[0043] Example 3:

[0044] Based on Embodiments 1 and 2, this invention further includes a guide sleeve 16 fixed to one end of the plug 14 near the adjusting rod 13. The end of the adjusting rod 13 is movably inserted into the guide sleeve 16, ensuring that the plug 14 moves coaxially with the first mounting cavity 11 during adjustment, thus preventing sealing failure caused by eccentric shaking. The adjusting rod 13 between the guide sleeve 16 and the fixed cylinder 15 is stepped and fitted with multiple disc springs 17.

[0045] like Figure 5 As shown, when the material contains large particles that cause blockage, the disc spring 17 is compressed, causing the plug 14 to move backward briefly to release pressure. After the particles pass through, the disc spring 17 returns to its original position, achieving pressure adaptive compensation and preventing overload of the plunger pump 2. Simultaneously, considering the rapid wear rate at the plug 14, a wear-resistant disc 18 is provided at the end of the plug 14 furthest from the adjusting rod 13. The wear-resistant disc 18 is made of zirconia ceramic material, and its surface has a conical groove that matches the conical structure at the front end of the plug 14. Thus, when the wear-resistant disc 18 is impacted by material, it can automatically align with the groove of the wear-resistant disc 18 through the conical surface of the plug 14, thus fitting the plug 14.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
