Description

Technical Field

[0001] This utility model relates to the field of black goji berry concentrate production technology, and in particular to a black goji berry concentrate anti-sedimentation storage tank. Background Technology

[0002] Black goji berries, as a plant resource used for both medicinal and edible purposes, are rich in various bioactive components such as anthocyanins, polysaccharides, and polyphenols. Among them, anthocyanins are particularly high, which are the main effective components for medical and health benefits and are known as "soft gold." With the popularization of health consumption concepts, deep-processed products developed from black goji berries are increasingly favored by the market.

[0003] Black goji berry concentrate is a concentrated liquid made from fresh black goji berries through processes such as washing, pressing, extraction, filtration, and concentration. In order to ensure the continuity of production, achieve uniform quality of different batches of products, and facilitate process adjustments and quality control before bottling, large storage tanks must be set up to temporarily store and mix the black goji berry concentrate. The storage tanks play a key role in buffering, mixing, and stabilizing the supply of materials in this process.

[0004] However, because black goji berries are rich in polysaccharides, pectin, protein, and high levels of anthocyanins, these components have poor physical stability during static storage after concentration, and are prone to precipitation due to gravity and intermolecular aggregation. Existing storage tanks are typically equipped with simple top-mounted stirrers, which tend to create a central vortex when dealing with the high viscosity and easily settling black goji berry concentrate. Furthermore, they lack sufficient shear force on the tank walls and bottom, easily creating dead zones in the stirring process. This causes the viscous concentrate to adhere to the tank walls and bottom, gradually forming a hard sediment layer. Utility Model Content

[0005] To address the problem in the background art that existing storage tanks are typically equipped with simple top-mounted agitators, which easily create central vortices and stirring dead zones, causing viscous concentrate to adhere to the tank walls and bottom and gradually form a hard sediment layer, this invention proposes an anti-sedimentation storage tank for black goji berry concentrate.

[0006] The technical solution of this utility model is: a sedimentation-proof storage tank for black goji berry concentrate, including a support frame and a tank body, wherein the tank body is fixedly mounted on the support frame by multiple mounting seats provided on its outer wall. The tank is equipped with a stirring assembly, which includes a main drive motor fixed on the tank cover. The output shaft of the main drive motor is vertically inserted into the tank and a stirring shaft is fixedly mounted thereon. Multiple sets of stirring impellers are fixedly mounted on the stirring shaft at intervals along its axial direction. Each set of impellers includes two blades arranged perpendicular to the stirring shaft. Multiple sets of impellers together form two rows of blades. Each row of blades has a fixed rod extending in the vertical direction at the end away from the stirring shaft. The fixed rod has multiple scrapers spaced apart along its length. The scrapers are made of flexible and wear-resistant material. The root of the scraper is fixed to the fixed rod. The scraper has a pre-bending deformation. The scraping end of the scraper can adaptively and elastically adhere to the inner wall of the tank by utilizing the elasticity and recovery force of the material itself.

[0007] Preferably, the scrapers on the two fixed rods are staggered vertically.

[0008] Preferably, the scraper has a hollow structure in the middle.

[0009] Preferably, the impeller is an axial flow impeller, and the blades of the impeller are set at an acute angle to the plane of rotation.

[0010] Preferably, the angle between the blade and the plane of rotation is 45°.

[0011] Preferably, the bottom of the tank is an arc-shaped conical head structure with a horizontal diameter that gradually decreases from top to bottom. The bottom of the tank is fixedly connected to and connected to a connecting pipe that extends downward. The bottom end of the connecting pipe is connected to a homogenizing tank through a flange. The bottom of the outer wall of the homogenizing tank is fixedly connected to and connected to a discharge pipe. A homogenizing mechanism is provided inside the homogenizing tank.

[0012] Preferably, the homogenizing mechanism includes a secondary drive motor fixedly mounted at the bottom center of the homogenizing tank. The output shaft of the secondary drive motor is rotatably inserted into the homogenizing tank through a mechanical seal and a rotating shaft is fixedly mounted thereon. Multiple connecting rods extending upward are fixedly mounted on the bottom inner wall of the homogenizing tank. The multiple connecting rods are evenly distributed along the circumferential direction of the rotating shaft. A stator housing is fixedly mounted on the top of the multiple connecting rods. The stator housing is a hollow cylindrical structure with an open top. The top of the rotating shaft is rotatably inserted into the stator housing and a rotor is fixedly mounted thereon. Multiple discharge holes are evenly distributed along the circumference of the stator housing.

[0013] Preferably, the homogenizing tank has a removable sight glass on its outer wall.

[0014] Advantages of this utility model: (1) This utility model adopts an axial flow impeller, which can generate a strong upward axial flow, realize the macroscopic whole tank circulation of materials, effectively stir the materials at the bottom of the tank, and at the same time, a flexible scraper is set on the impeller, which uses its own elasticity to continuously stick to and scrape the inner wall of the tank, removes the wall adhesion layer that traditional agitators cannot handle, realizes the self-cleaning of the tank wall, and avoids the viscous concentrated slurry from adhering to the tank wall and gradually forming a hard sediment layer.

[0015] (2) By setting up a two-stage structure consisting of a main tank and a homogenizing tank, and combining it with the arc-shaped conical end cap design at the bottom of the tank, this utility model avoids the viscous concentrated slurry from adhering to the bottom of the tank and gradually forming a hard sediment layer. At the same time, it forces all materials to flow through the homogenizing mechanism at the bottom before discharge. This mechanism, through the triple action of intense mechanical shearing, high-speed impact and cavitation effect generated by the rotor and stator, can finely break down and homogenize the concentrated slurry, especially the stubborn sediment clumps, at the microscopic level. Ultimately, it significantly improves the product's delicate taste and physical stability, and effectively delays the recurrence of sedimentation. Attached Figure Description

[0019] 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.

[0020] Example 1: A sediment-proof storage tank for concentrated black goji berry pulp, such as... Figure 1-4 As shown, the storage tank includes a support frame 1 and a tank body 2. The tank body 2 is fixedly mounted on the support frame 1 by multiple mounting seats on its outer wall. One side of the support frame 1 is provided with an operating platform 101 with a guardrail 103. The edge of the operating platform 101 is provided with a downward-sloping ladder 102 with a guardrail 103. The operating platform 101 is provided with a control panel 3 for centralized control of the electrical components of the storage tank.

[0021] The tank body 2 is a hollow cylindrical structure with an opening at the top. The opening of the storage tank 2 is sealed with an openable tank cover 4 by a flange. The tank cover 4 is equipped with a feed pipe 401 that communicates with the inside of the tank body 2, which is used to feed black goji berry concentrated pulp into the tank.

[0022] The tank 2 is equipped with a stirring assembly that can stir the black goji berry concentrate inside. Specifically, the stirring assembly includes a main drive motor 5 fixed on the tank cover 4. The output shaft of the main drive motor 5 is vertically inserted into the tank 2 and a stirring shaft 6 is fixed thereon. Multiple sets of stirring impellers 7 are fixed on the stirring shaft 6 and spaced apart along its axial direction. When the main drive motor 5 drives the stirring shaft 6 to rotate, the multiple sets of stirring impellers 7 generate an upward axial flow, forming an upward liquid flow from the bottom of the tank to the top of the tank. This can effectively eliminate the concentration gradient of the material inside the tank and continuously lift the black goji berry concentrate components with higher density and easy to settle at the bottom of the tank to the upper part of the tank, so as to achieve uniform mixing of the material.

[0023] The impeller 7 is an axial flow impeller. Each set of impellers 7 includes two blades perpendicular to the stirring shaft 6. The blades are at a 45° angle to the plane of rotation. Multiple sets of impellers 7 together form two rows of blades. Each row of blades has a fixed rod 8 extending vertically fixed at one end away from the stirring shaft 6. The fixed rod 8 has multiple scrapers 9 spaced apart along its length. The scrapers 9 are made of food-grade flexible wear-resistant material, preferably polyurethane board. The root of the scraper 9 is fixed to the fixed rod 8 with screws. When the scraper 9 is installed, the body of the scraper 9 is pre-bent and deformed so that its scraping end tends to stick to the tank wall even without load. Utilizing the elasticity and resilience of the polyurethane material itself, in the working state, its scraping end can adaptively and tightly elastically stick to the inner wall of the tank 2 to perform scraping operation on the inner wall of the tank 2.

[0024] The scrapers 9 on the two fixed rods 8 are staggered vertically, so that the scraping areas of the two sets of scrapers 9 complement each other in the axial height of the tank wall. While completing the comprehensive scraping operation of the inner wall of the tank 2, it effectively reduces the number of scrapers 9 on a single fixed rod, thereby reducing manufacturing costs and stirring resistance.

[0025] The scraper blade 9 has a hollow structure in the middle, which helps to reduce the overall weight of the scraper blade 9, reduce the operating load of the mixing component, and at the same time reduce the adhesion of materials on the scraper blade surface, thus improving the self-cleaning ability.

[0026] The bottom of tank 2 is a circular arc conical head structure with a horizontal diameter that gradually decreases from top to bottom. This structure can guide the material inside the tank, including easily settling components, to naturally converge towards the bottom center. The bottom of tank 2 is fixedly connected to and connected to a downwardly extending connecting pipe 10. The bottom end of the connecting pipe 10 is connected to a homogenizing tank 11 through a flange. The inner diameter of the homogenizing tank 11 is smaller than that of tank 2. This small-volume homogenizing tank 11 can concentrate the material processing area, making the subsequent homogenization energy more concentrated, thereby greatly improving the homogenization efficiency. The bottom of the outer wall of the homogenizing tank 11 is fixedly connected to and connected to a discharge pipe 12.

[0027] The homogenizing tank 11 is equipped with a homogenizing mechanism. Specifically, the homogenizing mechanism includes a secondary drive motor 13 fixed at the bottom axis of the homogenizing tank 11. The output shaft of the secondary drive motor 13 rotates through the homogenizing tank 11 via a mechanical seal and is fixedly mounted on a rotating shaft 14. Multiple upwardly extending connecting rods 15 are fixedly mounted on the bottom inner wall of the homogenizing tank 11. These connecting rods 15 are evenly distributed along the circumferential direction of the rotating shaft 14. The top ends of the multiple connecting rods 15 are jointly fixed to a stator housing 16. The multi-point support structure formed by the multiple connecting rods 15 ensures the stability of the stator housing 16, providing a guarantee for high-speed precision packaging. The stator housing 16 is an open-top cylindrical hollow structure. The top end of the rotating shaft 14 rotates through the stator housing 16 and is fixedly mounted on a rotor 17. When the secondary drive motor 13 starts... The rotor 17 rotates at high speed inside the stator housing 16, generating a strong centrifugal force. This force draws the material flowing in from the connecting pipe 10 through the upper opening of the stator housing 16 and forces it through the extremely small gap between the rotor 17 and the inner wall of the stator housing 16. The outer wall of the stator housing 16 has multiple discharge holes 18 evenly distributed along its circumference. When the material passes through the tiny gap, it is subjected to intense mechanical shearing. Subsequently, when it is ejected at high speed from the discharge holes 18 on the side wall of the stator housing 16, it is subjected to further impact and cavitation effects. Under the combined effect of shearing, impact, and cavitation, the particulate agglomerates, pulp fibers, etc. in the black goji berry concentrate can be thoroughly broken up, homogenized, and refined, thereby significantly improving the product's smoothness and physical stability, and effectively delaying the occurrence of sedimentation and stratification.

[0028] Large, possibly hardened or formed, adhering materials scraped off from the inner wall of the tank 2 by the scraper 9 will be carried to the bottom of the tank by the axial circulating flow and enter the homogenizing tank 11 through the connecting pipe 10. The homogenizing mechanism, with its powerful mechanical shearing force, can effectively crush, disperse, and rehomogenize these large, stubborn agglomerates, avoiding secondary pollution and achieving material recovery and quality improvement.

[0029] A sight glass 19 is connected to the outer wall of the homogenizing tank 11 via a flange. The sight glass 19 is a detachable structure, which allows operators to directly observe the flow state of the material inside the homogenizing tank 11, the homogenization effect, and the operation of the rotor 17. This enables real-time, visual monitoring of the production process, facilitating timely adjustment of process parameters and rapid maintenance and diagnosis. If the homogenization effect decreases or abnormal noise occurs, the detachable sight glass 19 provides a convenient inspection channel for checking whether the discharge port of the stator housing 16 is blocked, or whether the rotor 17 is worn or jammed by foreign objects. This eliminates the need to disassemble the entire homogenizing tank 11, greatly simplifying the maintenance process and shortening downtime.

[0030] Working principle: When stirring the black goji berry concentrate in the storage tank, the main drive motor 5 is started, which drives the stirring shaft 6 and the axial flow stirring impeller 7 to rotate. A strong upward axial flow is generated from the bottom to the top of the tank, which lifts the bottom sediment into the main flow. At the same time, the flexible scraper 9 fixed on the stirring system moves circumferentially with the fixed rod 8. It uses its elastic deformation to closely adhere to the inner wall of the tank, scraping off the continuously generated wall adhesion layer and bringing it into the main circulation flow.

[0031] Under the action of axial circulation, all materials are effectively collected by the arc-shaped conical head structure at the bottom of the tank 2, and are all and forcibly transported to the homogenizing tank 11 below through the connecting pipe 10. The materials entering the small-volume homogenizing tank 11 are sucked into the stator housing 16 by the high-speed rotating rotor 17. When the materials pass through the extremely small gap between the rotor and the stator, they are subjected to severe mechanical shearing. When they are ejected at high speed from the discharge hole 18 on the side wall of the stator, they are subjected to further impact and cavitation effect. Under these three actions, the particulate agglomerates, fruit pulp fibers and large precipitates scraped off from the tank wall in the materials are completely broken up, crushed and homogenized, and finally a concentrated slurry with uniform texture and high stability is formed, which is discharged from the discharge pipe 12.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
