Description

Technical Field

[0001] This invention relates to the field of dairy processing technology, specifically a colloid mill for dairy processing. Background Technology

[0002] Dairy products are foods made primarily from cow's or sheep's milk and their processed products, with or without added vitamins and other auxiliary ingredients. They are also known as cream products and mainly include seven categories: liquid milk, milk powder, condensed milk, milk fat, cheese, and milk ice cream. Among them, milk fat products include cream, light cream, and other products, which must meet standards such as fat content ≥80% and total bacterial count ≤10^5 CFU / g. The production processes include pasteurization and ultra-high temperature instantaneous sterilization.

[0003] Dairy products often form solid lumps or stick together during processing, so they need to be ground, pulverized, and emulsified using colloid mill equipment to ensure uniform mixing.

[0004] An investigation revealed that an invention patent (publication number: CN110013908B) discloses a colloid mill for dairy product processing, comprising a drive motor, a grinding mill base, a guide sleeve, a fixed buffer seat, a discharge pipe, an automatic dairy product detection and diversion device capable of pressurization and lifting, a return material lifting pipe, a feed funnel, and grinding media. The drive motor is embedded in the upper surface of the grinding mill base, with its shaft perpendicular to the upper surface of the base. A fixed buffer seat is located to the left of the drive motor and is mounted on the same horizontal plane. The bottom end of the fixed buffer seat is welded to the upper surface of the grinding mill base. This invention uses a filter screen to classify dairy products. Finished dairy products pass through and flow out, while unfinished products remain, avoiding rework and increasing workload. Simultaneously, by adjusting the discharge stop and then pressurizing, unfinished products are reprocessed, reducing the return flow of dairy products and preventing blockages and malfunctions.

[0005] Although the aforementioned patent achieves the goal of pressurizing the gas through the booster pipe into the pipe valve body and then into the discharge trough through the connecting pipe, the unfinished dairy products move to the right from the right side of the screen under pressure and are obliquely upward by the baffle. They then enter the feed funnel through the diversion pipe to the return lifting pipe for rework, and the dairy products are classified by the filter screen. The finished dairy products pass through and flow out, while the unfinished ones are reworked, resulting in a large workload.

[0006] However, during the use of colloid mills for dairy processing, it is necessary to rework the dairy products that have not been ground. Therefore, a rework pipe needs to be installed on the surface of the colloid mill to transport the dairy products that have not been ground to the feed inlet of the colloid mill, so that the dairy products can be ground again by the colloid mill.

[0007] However, due to unreasonable pipeline design, flow blind spots are formed. For example, excessively small bend angles or sudden changes in pipe diameter cause dairy products to remain inside the rework pipeline for a long time, preventing them from entering the colloid mill for reprocessing. This not only wastes unprocessed dairy products, but also causes them to spoil due to prolonged retention. During the reprocessing of other dairy products, the spoiled dairy products enter the colloid mill along with other dairy products, contaminating the new dairy products and affecting the yield of high-quality dairy products.

[0008] Therefore, the present invention provides a colloid mill for dairy processing to solve the above-mentioned problems. Summary of the Invention

[0009] (I) Technical Problem to be Solved The present invention provides a colloid mill for dairy processing, which aims to solve the problems mentioned in the background art.

[0012] The reflux mechanism includes a protective plate mounted in a path array on the surface of the grinding mechanism. A power supply assembly is attached to one side of the protective plate. A conductive rod electrically connected to the power supply assembly is fixedly connected to one side of the power supply assembly. A connecting ring is attached to one side of the conductive rod. An electromagnet is fixedly connected inside the connecting ring. A conductive groove corresponding to the conductive rod is opened on one side of the connecting ring.

An arc-shaped filter screen plate installed inside the grinding assembly is attached to the surface of the pressing and collecting plate, and a guide plate is fixedly connected to one side of the upper surface of the arc-shaped filter screen plate.

[0014] As a preferred technical solution of this application, the grinding assembly includes a grinding housing, with discharge grooves on both sides of the surface of the grinding housing, a feed hopper fixedly connected to the upper surface of the grinding housing, a protective plate fixedly connected to the inside of the grinding housing, a power supply assembly, a connecting ring and an arc-shaped filter screen plate all installed inside the grinding housing, and a drive motor fixedly connected to one side of the grinding housing.

[0015] As a preferred technical solution of this application, the extension mechanism includes a hollow plate fixedly connected inside the grinding shell and corresponding to the guide plate, an extension plate corresponding to the grinding shell being slidably connected inside the hollow plate, and a rotating plate slidably connected to the hollow plate being fixedly connected to one side of the extension plate in a symmetrical manner, the rotating plate being slidably connected to the grinding shell.

[0016] As a preferred technical solution of this application, the extension mechanism further includes an extension block fixedly connected to the other side of the extension plate in a path array and corresponding to the extrusion collection plate. The surface of the extension plate is provided with a number of corresponding through slots in a rectangular array. The number of rotating plates and the extension block are slidably connected to the interior of the corresponding through slots. The surfaces of the number of rotating plates are jointly fitted with a sliding block that is slidably connected to the grinding shell.

[0017] As a preferred technical solution of this application, the filtration and recycling mechanism includes an arc-shaped plate rotatably connected to the other side of the upper surface of the arc-shaped filter screen plate, a rotating rod fixedly connected to the lower surface of the arc-shaped plate, a servo motor fixedly connected to one end of the rotating rod and fixedly connected to the arc-shaped filter screen plate, and magnetic suction plates fixedly connected to the opposite sides of the arc-shaped plate and the hollow plate.

[0018] As a preferred technical solution of this application, the filtration and recovery mechanism further includes a three-way water pipe fixedly connected to one side of the grinding housing and communicating with the grinding housing. A valve is fixedly connected to one side of the three-way water pipe, and a sealing block that is slidably connected to one end of the three-way water pipe is slidably connected inside the grinding housing.

[0019] As a preferred technical solution of this application, the filtration and recovery mechanism further includes a threaded rod that is threaded to the surface of the sealing block and rotatably connected to the inside of the grinding housing. One end of the threaded rod is fixedly connected to a DC motor. The sealing block corresponds to the arc plate, and the arc plate and the hollow plate are used to isolate the sealing block from the inside of the grinding housing.

[0020] As a preferred technical solution of this application, the grinding mechanism includes grinding rollers rotatably connected to the inside of the grinding housing in a path array. Each grinding roller has a rotating roller rotatably connected to the grinding housing on its surface. One end of one of the rotating rollers is fixedly connected to a drive motor. The power supply component is fixedly connected to both sides of the corresponding rotating roller. Several rotating rollers are rotatably connected to a protective plate.

[0021] As a preferred technical solution of this application, the grinding mechanism further includes a linkage gear fixedly connected to the surface of the rotating roller, wherein the surfaces of the two linkage gears are meshed with connecting gears, and the surfaces of the two connecting gears are jointly fixedly connected to a support rod rotatably connected to the grinding housing. The linkage rod corresponds to the rotating roller, and based on the cooperation of the linkage gear and the connecting gear, it drives the two adjacent grinding rollers to rotate in opposite directions.

[0022] (III) Beneficial Effects

[0023] Based on the cooperation of the reflux mechanism and the grinding mechanism, the dairy products are conveyed to the grinding rollers through the feed hopper. The drive motor is started, and based on the cooperation of the linkage gear and the connecting gear, the adjacent grinding rollers rotate in opposite directions to grind the dairy products. The ground dairy products are filtered through the arc-shaped filter screen and discharged through the discharge chute. For dairy products that cannot be filtered, the electromagnet is energized to generate magnetic force, so that the connecting ring is connected to the rotating roller through the electromagnet. The rotating roller drives the linkage rod and the extrusion collection plate to rotate on the surface of the arc-shaped filter screen, pushing the unground dairy products through the arc plate and the hollow plate to the corresponding two grinding rollers for further grinding. This achieves circulating grinding inside the grinding shell, avoiding the problem of unground dairy products remaining in the pipes for a long time and affecting the grinding of other dairy products.

[0024] Based on the cooperation of the reflux mechanism and the extension mechanism, when the extrusion collection plate pushes the unfinished dairy products, the extrusion collection plate and the extension block are in contact, so that the extension block pushes the extension plate to move. This allows the extension plate to guide the dairy products while blocking the dairy products entering the grinding shell through the feed hopper, so that the dairy products move to other grinding rollers. This prevents new dairy products and re-returned dairy products from entering the corresponding grinding rollers at the same time, which would cause high-load operation of adjacent grinding rollers and damage.

[0025] Based on the extension mechanism and other structural features, during the reprocessing of incompletely ground dairy products, the extension plate moves, causing the rotating plate to rotate both inside and outside the grinding housing. This rotation pushes the sliding block against the grinding housing, obstructing the interior and adjusting the feed speed. This ensures that the speed at which the dairy products enter the grinding housing is linked to the reprocessing process. During reprocessing, the feed speed is reduced, lowering the load on the grinding rollers and further preventing damage caused by high-load operation. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides a colloid mill for dairy product processing, with reference to... Figure 1 - Figure 9 As shown, three embodiments are provided:

[0039] Example 1:

[0040] The colloid mill for dairy processing includes a grinding assembly 1, a grinding mechanism 2 installed inside the grinding assembly 1, a reflux mechanism 3 installed on the surface of the grinding mechanism 2, a filter recovery mechanism 4 installed on the surface of the reflux mechanism 3, and an extension mechanism 5 installed inside the grinding assembly 1 near the reflux mechanism 3.

[0041] The grinding assembly 1 includes a grinding housing 101. Discharge grooves 102 are provided on both sides of the surface of the grinding housing 101. A feed hopper 103 is fixedly connected to the upper surface of the grinding housing 101. A protective plate 301 is fixedly connected to the inside of the grinding housing 101. A power supply assembly 302, a connecting ring 304, and an arc-shaped filter screen 309 are all installed inside the grinding housing 101. A drive motor 104 is fixedly connected to one side of the grinding housing 101.

[0042] The grinding housing 101 is used to isolate the grinding mechanism 2, the reflux mechanism 3, and the extension mechanism 5, etc., to prevent the external environment from affecting the dairy processing.

[0043] The discharge trough 102 is used to discharge the finished grinding dairy products;

[0044] The feed hopper 103 is used to transport dairy products into the interior of the grinding housing 101;

[0045] Among them, the drive motor 104 is used to drive the grinding mechanism 2 to grind the dairy products;

[0046] Specifically, the dairy products to be processed are conveyed into the interior of the grinding housing 101 through the feed hopper 103, so that they come into contact with the grinding mechanism 2;

[0047] The reflux mechanism 3 includes a protective plate 301 mounted in a path array on the surface of the grinding mechanism 2. A power supply assembly 302 is attached to one side of the protective plate 301. A conductive rod 303 electrically connected to the power supply assembly 302 is fixedly connected to one side of the power supply assembly 302. A connecting ring 304 is attached to one side of the conductive rod 303. An electromagnet 305 is fixedly connected inside the connecting ring 304. A conductive groove 306 corresponding to the conductive rod 303 is opened on one side of the connecting ring 304. The electromagnet 305 is electrically connected to the power supply assembly 302 through the conductive groove 306 and the conductive rod 303.

[0048] Among them, the protective plate 301 is used to limit the dairy products and prevent them from sliding inside the grinding shell 101 and affecting the electromagnet 305 and the power supply component 302.

[0049] The power supply component 302 is used to supply power to the electromagnet 305;

[0050] The conductive rod 303 is used to transfer electricity to the electromagnet 305, so that the electromagnet 305 is energized.

[0051] The connecting ring 304 is rotatably connected to the grinding housing 101 via a rotating shaft, and the connecting ring 304 is used to protect the electromagnet 305.

[0052] Among them, the electromagnet 305 is used to generate magnetic force, so that the connecting ring 304 can rotate with the grinding mechanism 2;

[0053] The conductive groove 306 is used to connect the ring 304 to rotate, and the conductive rod 303 continuously supplies power to the electromagnet 305.

[0054] The reflux mechanism 3 also includes linkage rods 307 fixedly connected to the surface of the connecting ring 304 in a path array. Several linkage rods 307 are fixedly connected to the surface of a pressing and collecting plate 308 that is linked with the electromagnet 305. An arc-shaped filter screen plate 309 installed inside the grinding assembly 1 is attached to the surface of the pressing and collecting plate 308. A guide plate 310 is fixedly connected to one side of the upper surface of the arc-shaped filter screen plate 309.

[0055] Among them, the linkage rod 307 is used to connect the connecting ring 304 to the extrusion collection plate 308;

[0056] The extrusion collection plate 308 rotates inside the grinding housing 101, pushing the dairy products that cannot be filtered on the arc-shaped filter screen plate 309.

[0057] Among them, the arc-shaped filter plate 309 is used to filter dairy products, so as to separate the ground dairy products from the unground dairy products;

[0058] Among them, the guide plate 310 is used to guide the extrusion collection plate 308 and limit the dairy products to prevent the dairy products from falling out of the grinding mechanism 2.

[0059] Specifically, after the dairy products enter the grinding housing 101 through the feed hopper 103, they are ground by the grinding mechanism 2, so that the dairy products fall onto the arc-shaped filter plate 309 through the grinding mechanism 2 and are filtered by the arc-shaped filter plate 309, so that the ground dairy products are discharged through the discharge trough 102.

[0060] After filtering the dairy products, the unground dairy products remain on the inner arc surface of the arc-shaped filter plate 309. Electrical energy is transmitted through the power supply assembly 302 and the conductive rod 303 to the electromagnet 305 via the conductive groove 306, causing it to generate magnetic force and be attracted to the grinding mechanism 2. The rotation of the grinding mechanism 2 drives the electromagnet 305 and the connecting ring 304 to rotate, thereby driving the linkage rod 307 to rotate synchronously. This causes the squeezing collection plate 308 to slide on the inner arc surface of the arc-shaped filter plate 309, pushing the unground dairy products. The dairy products follow the squeezing collection plate 308 to the top of the grinding mechanism 2, and by gravity, they fall into the grinding mechanism 2 for re-grinding. This achieves the effect of reworking the unground dairy products inside the grinding housing 101, avoiding the need for external pipelines to circulate and rework the dairy products. This also avoids the waste of dairy products caused by reworked dairy products remaining inside the pipeline and the possibility of contamination of other dairy products.

[0061] In Embodiment 2, based on Embodiment 1, the grinding mechanism 2 further includes grinding rollers 201 rotatably connected in a path array inside the grinding housing 101. Each grinding roller 201 has a rotating roller 202 rotatably connected to the grinding housing 101 fixedly connected to its surface. One end of one rotating roller 202 is fixedly connected to the drive motor 104. The power supply assembly 302 is fixedly connected to both sides of the corresponding rotating roller 202. Several rotating rollers 202 are rotatably connected to the protective plate 301.

[0062] Among them, the grinding roller 201 is used to grind dairy products;

[0063] The rotating roller 202 is used to provide power to the grinding roller 201;

[0064] The grinding mechanism 2 also includes linkage gears 203 fixedly connected to the surface of the rotating roller 202. The surfaces of the two linkage gears 203 are meshed with connecting gears 204. The surfaces of the two connecting gears 204 are fixedly connected to a support rod that is rotatably connected to the grinding housing 101. The linkage rod 307 corresponds to the rotating roller 202. Based on the cooperation of the linkage gears 203 and the connecting gears 204, it drives the two adjacent grinding rollers 201 to rotate in opposite directions. The linkage gears 203 and the connecting gears 204 cooperate with each other to make the adjacent grinding rollers 201 rotate in opposite directions, thereby achieving the grinding of dairy products.

[0065] The support rod is used to support the connecting gear 204;

[0066] Specifically, after the dairy products enter the grinding housing 101, they fall onto the corresponding grinding roller 201 by gravity. The drive motor 104 is started, and its output end drives the corresponding rotating roller 202 to rotate, causing the corresponding grinding roller 201 to rotate. Through the mutual cooperation of the linkage gear 203 and the connecting gear 204, the two adjacent grinding rollers 201 rotate in opposite directions to grind the dairy products.

[0067] The extension mechanism 5 includes a hollow plate 501 fixedly connected inside the grinding housing 101 and corresponding to the guide plate 310. An extension plate 502 corresponding to the grinding housing 101 is slidably connected inside the hollow plate 501. A rotating plate 503 slidably connected to the hollow plate 501 is fixedly connected to one side of the extension plate 502 in a symmetrical manner. The rotating plate 503 is slidably connected to the grinding housing 101.

[0068] Among them, the hollow plate 501 is used to guide the extrusion collection plate 308 and limit the dairy products;

[0069] The extension plate 502 is used to guide the dairy products entering the grinding housing 101;

[0070] Among them, the rotating plate 503 is used to push the sliding block 506 to move;

[0071] The extension mechanism 5 also includes an extension block 504 that is fixedly connected to the other side of the extension plate 502 in a path array and corresponds to the extrusion collection plate 308. The surface of the extension plate 502 is provided with a number of corresponding through slots 505 in a rectangular array. A number of rotating plates 503 and the extension block 504 are slidably connected to the inside of the corresponding through slots 505. The surfaces of the rotating plates 503 are together attached to a sliding block 506 that is slidably connected to the grinding housing 101.

[0072] The extension block 504 is used to fit with the extrusion collection plate 308, so that the extrusion collection plate 308 can drive the extension plate 502 to move.

[0073] The through slot 505 provides space for the extension block 504 and the rotating plate 503 to slide;

[0074] The sliding block 506 is used to adjust the speed at which the dairy products enter the grinding housing 101;

[0075] Specifically, when reworking and re-grinding incompletely ground dairy products, the extrusion collection plate 308 moves in contact with the extension block 504, causing the extension block 504 to drive the extension plate 502 to move. This allows the extension plate 502 to guide the dairy products entering the grinding housing 101, causing them to fall onto the grinding roller 201 on the other side for grinding. The extension plate 502 prevents the dairy products from falling onto the grinding roller 201 below it, allowing the grinding roller 201 below the extension plate 502 to re-grind the reworked dairy products, while the other grinding roller 201 grinds newly entering dairy products.

[0076] By setting the rotating plate 503, when the extension plate 502 slides, it drives the rotating plate 503 to slide synchronously, so that it rotates around the rotating roller 202 as the center. This causes the rotating plate 503 to drive the sliding block 506 to move upward, so that the sliding block 506 is inserted into the inside of the grinding housing 101, blocking the position where dairy products are added to the grinding housing 101. This reduces the speed at which dairy products enter the grinding housing 101, and avoids the situation where the raw material enters at a constant speed, causing reworked dairy products to be ground at the same time, resulting in a high load on the grinding roller 201, which may cause damage to the grinding roller 201.

[0077] In Example 3, based on Examples 1 and 2, the filter recovery mechanism 4 further includes an arc plate 401 rotatably connected to the other side of the upper surface of the arc-shaped filter screen 309. A rotating rod 402 is fixedly connected to the lower surface of the arc plate 401. A servo motor 403 fixedly connected to the arc-shaped filter screen 309 is fixedly connected to one end of the rotating rod 402. Magnetic plates 404 are fixedly connected to the opposite sides of the arc plate 401 and the hollow plate 501.

[0078] Among them, the arc-shaped plate 401 is used to isolate dairy products;

[0079] Among them, the rotating rod 402 is used to drive the arc plate 401 to rotate;

[0080] The servo motor 403 is used to provide power to the rotating rod 402;

[0081] Among them, the magnetic plate 404 is used to make the arc plate 401 and the hollow plate 501 more tightly sealed;

[0082] The filter recovery mechanism 4 also includes a three-way water pipe 405 fixedly connected to one side of the grinding housing 101 and communicating with the grinding housing 101. A valve is fixedly connected to one side of the three-way water pipe 405, and a sealing block 406 that is in contact with one end of the three-way water pipe 405 is slidably connected inside the grinding housing 101.

[0083] Among them, the three-way water pipe 405 is used to drain dairy products that cannot be ground;

[0084] Among them, the valve is used to control the opening and closing of the three-way water pipe 405;

[0085] Among them, the sealing block 406 is used to seal the three-way water pipe 405 to prevent the dairy products from entering the three-way water pipe 405 during the grinding process of the grinding mechanism 2.

[0086] The filter recovery mechanism 4 also includes a threaded rod 407 that is threaded to the surface of the sealing block 406 and rotatably connected to the inside of the grinding housing 101. One end of the threaded rod 407 is fixedly connected to a DC motor 408. The sealing block 406 corresponds to the arc plate 401. The arc plate 401 and the hollow plate 501 are used to isolate the sealing block 406 from the inside of the grinding housing 101.

[0087] Among them, the threaded rod 407 and the DC motor 408 are used to drive the sealing block 406 to move;

[0088] Specifically, after the dairy products are ground, the rotation of the extrusion collection plate 308 moves the last remaining unground dairy products on the arc-shaped filter plate 309 to the arc-shaped plate 401. The servo motor 403 is then activated, causing its output to drive the rotating rod 402 and the arc-shaped plate 401 to rotate, thus removing them from contact with the hollow plate 501. Simultaneously, the DC motor 408 is activated, causing its output to drive the threaded rod 407 to rotate, causing the sealing block 406 to move upward and no longer seal the three-way water pipe 405. This allows the dairy products to pass through the arc-shaped plate 401 into the three-way water pipe 405, and the valve is opened to discharge the dairy products, completing the dairy product processing.
