Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically a grinding component for a soybean lecithin grinding device that is easy to disassemble and clean. Background Technology

[0002] Soybeans are an annual herbaceous plant and an extremely important legume crop globally. The cultivated soybeans widely grown today evolved from wild soybeans through long-term targeted selection, improvement, and domestication. They are not only an important food crop for humans but also a special crop whose seeds are rich in plant protein, with a protein content reaching 35%-40%, far exceeding most grains, thus holding a vital position in the dietary structure.

[0003] Soybean lecithin is a core product extracted from the oil residue produced during soybean oil production. It has a complex composition and diverse functions, primarily consisting of various active phospholipids such as lecithin, cephalin, and inositol phospholipids. These components possess both hydrophilic and lipophilic properties. In the food industry, they are commonly used as emulsifiers and stabilizers in baked goods, beverages, and confectionery. In the pharmaceutical industry, they can be used to prepare liposome drug carriers and nutritional supplements. This wide applicability makes it a highly valuable bioactive substance.

[0004] In the industrial production process of soybean phospholipids, the grinding stage is one of the key steps determining product quality. This stage breaks down the phospholipid particles in the soybean oil residue, allowing them to be fully released and evenly dispersed. This directly affects the efficiency of subsequent separation and purification, as well as the purity of the final product. However, existing grinding equipment generally has flaws in its cleaning and maintenance design: the complex structure of the grinding chamber makes it difficult to completely remove material residues, especially in corners and crevices, which easily become "cleaning dead zones." Residual phospholipid components may oxidize and deteriorate, leading to batch contamination. Furthermore, traditional grinding equipment requires a significant amount of manpower to disassemble and clean. Utility Model Content

[0005] The purpose of this invention is to provide a grinding component for a soybean lecithin grinding device that is easy to disassemble and clean, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grinding component for a soybean lecithin grinding device that is easy to disassemble and clean, comprising a main body, a shell mounted on the main body, a discharge port provided on the shell, a loading port provided above the discharge port, a grinding chamber provided below the loading port, a collection chamber provided below the grinding chamber, and a drive module mounted below the collection chamber.

[0007] Preferably, the feeding port includes a feeding ramp, and a connecting flange is installed below the feeding ramp, which is connected to the bearing above the stationary grinding disc.

[0008] Preferably, the grinding chamber includes a stationary grinding disc and a moving grinding disc. The stationary grinding disc connects the inner grinding disc to the positioning pin inside the outer casing through the positioning hole below, thereby achieving positioning and installation. At the same time, it is connected to the loading port through the bearing provided above the inner grinding disc to prevent material leakage.

[0009] Preferably, the moving grinding disc includes an outer grinding disc, and a connecting shaft is provided in the middle of the outer grinding disc. The outer grinding disc can be connected to the output shaft above the drive motor through the connecting shaft so that they rotate synchronously.

[0010] Preferably, a support platform is provided on the inner side of the outer shell, a positioning pin is provided above the support platform, and a synchronous connection flange is provided in the middle of the support platform.

[0011] Preferably, all the flanges are provided with multiple layers of sealing rings at the connection to prevent the seepage of juice during grinding.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This easily disassembled and cleaned soybean lecithin grinding device uses grinding components. In the raw material processing stage, the feed ramp at the loading port guides the material to slide down quickly at a scientifically inclined angle. It precisely connects with the connecting flange and the bearing above the stationary grinding disc, preventing material spillage and waste during the feeding process and ensuring continuous feeding. Simultaneously, the support platform and positioning pins inside the outer shell cooperate to provide stable support for both the stationary and moving grinding discs, effectively reducing vibration even under high-speed grinding conditions and ensuring stable operation during the grinding process. Regarding grinding efficiency, the stationary grinding disc is precisely positioned and installed via positioning holes and positioning pins inside the outer shell. The bearing above the inner grinding disc is tightly connected to the loading port. This dual protection stabilizes the position of the stationary grinding disc and forms a sealed space to prevent material leakage. Meanwhile, the moving grinding disc... The outer grinding disc is connected to the output shaft of the drive motor via a connecting shaft, enabling high-speed synchronous rotation and forming a grinding gap with the stationary grinding disc. This dynamic-static grinding mode can grind soybean lecithin raw materials to a fine consistency, fully meeting the stringent requirements of the product for particle uniformity and fineness, and ensuring product quality from the source. Addressing the pain points of cleaning and maintaining production equipment, this component adopts a flange connection structure that is easy to disassemble quickly. After the grinding operation is completed, the operator can separate the components without the need for complicated tools. Furthermore, all flange connections are equipped with multiple layers of sealing rings. These rings can effectively prevent juice from seeping into the equipment during grinding, avoiding corrosion of key components, and can also reduce material adhesion, making it easier to rinse away residual materials during cleaning, thereby significantly shortening the equipment cleaning time.

[0017] 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.

[0018] Example: Please refer to Figure 1 This utility model provides a technical solution: a grinding component for a soybean lecithin grinding device that is easy to disassemble and clean, including a main body 1, a shell 2 installed on the main body 1, a discharge port 3 provided on the shell 2, a loading port 4 provided above the discharge port 3, a grinding chamber 5 provided below the loading port 4, a collecting chamber 6 provided below the grinding chamber 5, and a drive module 7 installed below the collecting chamber 6.

[0019] The loading port 4 includes a feeding inclined plate 8, and a connecting flange 9 is installed below the feeding inclined plate 8, which is connected to the bearing 10 above the stationary grinding disc.

[0020] In this embodiment, the material can be effectively guided to slide down quickly and smoothly. A highly precise connection is achieved between the feed ramp, the connecting flange, and the bearing above the stationary grinding disc. On the one hand, this prevents material from spilling and being wasted during the feeding process; on the other hand, this connection ensures the continuity of feeding, preventing the entire production process from being interrupted or stalled due to discontinuous feeding.

[0021] The grinding chamber 5 includes a stationary grinding disc and a moving grinding disc. The stationary grinding disc connects the inner grinding disc 11 to the positioning pin 17 inside the outer shell 2 through the positioning hole 13 below to achieve positioning installation. At the same time, it is connected to the loading port 4 through the bearing 10 set above the inner grinding disc 11 to prevent material leakage.

[0022] The moving grinding disc includes an outer grinding disc 14, and a connecting shaft 15 is provided in the middle of the outer grinding disc 14. The outer grinding disc 14 can be connected to the output shaft above the drive motor 16 through the connecting shaft 15 so that it can rotate synchronously.

[0023] In this embodiment, the stationary grinding disc is precisely positioned and installed via positioning holes and positioning pins inside the outer casing, ensuring it remains firmly in the correct place to function. The bearing above the inner grinding disc is tightly connected to the feeding port, further stabilizing the stationary grinding disc's position and preventing it from shifting or shaking during grinding, while also creating a sealed space to effectively prevent material leakage. The outer grinding disc of the moving grinding disc is connected to the output shaft of the drive motor via a connecting shaft, enabling the moving grinding disc to rotate synchronously at high speed. When the moving grinding disc rotates at high speed, a grinding gap is formed between it and the stationary grinding disc, allowing the soybean lecithin raw material to be ground to a very fine degree.

[0024] The inner side of the outer shell 2 is provided with a support platform 18, a positioning pin 17 is provided above the support platform 18, and a synchronous connection flange 19 is provided in the middle of the support platform 18.

[0025] In this embodiment, extremely stable support is provided for both the stationary and moving grinding discs. This stable support effect is particularly evident under high-speed grinding conditions, effectively reducing equipment vibration even when the equipment is operating at high speed. This ensures smooth operation of the grinding process, preventing vibration from affecting the grinding effect and quality.

[0026] All flanges are equipped with multiple layers of sealing rings at the connection points to prevent the seepage of juices during grinding.

[0027] In this embodiment, it is very effective in preventing juice from seeping into the equipment and also reduces material adhesion. This significantly shortens the equipment cleaning time.

[0028] Working Principle: In actual operation, firstly, the outer grinding disc 14 is placed stably in the center of the support platform 18, and coaxially connected with the output shaft of the drive motor 16 via the connecting shaft 15, ensuring uniform torque transmission without sway during the transmission process. Then, the positioning hole 13 of the inner grinding disc 11 is aligned with the positioning pin 17 at the bottom of the outer casing 2, and it is securely positioned using an embedded installation method. The cover plate 12 is then bolted to the outer casing 2 to form a closed grinding chamber structure. Next, the feed ramp 8 and bearing 10 are detachably fixed via the connecting flange 9, ensuring smooth connection between the material conveying path and the grinding chamber 5.

[0029] When the equipment is started, the material enters the inclined feed plate 8 through the feeding port 4 and slides into the grinding chamber 5 at a uniform speed under the action of gravity. At this time, the drive motor 16 drives the outer grinding disc 14 to rotate, and the densely distributed grinding teeth on its surface form an intense shearing and grinding field with the stationary inner grinding disc 11. Under the action of centrifugal force, the material is squeezed into the gap between the inner and outer grinding discs, and fine grinding is achieved through high-frequency friction, impact and shearing action between the teeth. Due to the reduced particle size and increased fluidity, the ground material falls into the collection chamber 6 through the bottom channel of the grinding chamber under the pushing of subsequent feeds, and is continuously discharged along the discharge port 3, forming a stable material processing flow.

[0030] After the grinding operation is completed, the disassembly and cleaning process of the equipment is designed to balance convenience and thorough cleaning. Operators only need to follow the reverse installation sequence: loosen the cover plate 12 bolts, disassemble the connecting flange 9, remove the inner grinding disc 11, and loosen the locking device between the connecting shaft 15 and the drive motor 16 to separate the core components such as the outer grinding disc 14 and the inner grinding disc 11 one by one. This modular design allows each grinding component to be removed individually, enabling targeted cleaning of areas prone to residue buildup, such as the gaps between the grinding disc teeth and the dead corners of the grinding chamber. This avoids the cleaning blind spots caused by the inability to disassemble traditional integrated structures.

[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
