Description

Technical Field

[0001] This invention relates to the field of soybean milk grinding technology, and more particularly to a fully automatic soybean milk maker. Background Technology

[0002] With increasing attention to healthy eating, soy milk, as a nutritious and easily digestible beverage, has gained more and more popularity. Users desire soy milk with a smooth texture and rich nutrition, thus placing higher demands on the performance and functionality of soy milk makers.

[0003] Traditional methods of grinding soybeans only allow for a single grinding process, which fails to completely grind the soybeans. Impurities such as soybean pulp and skins remain in the soy milk, affecting its taste. Furthermore, the short grinding time prevents the full release of nutrients, resulting in a bland taste and reduced nutritional value. In particular, increasing the yield and quality of soy milk requires manual intervention for each grinding cycle, with the soybean pulp being re-loaded into the grinder. This process is not only time-consuming and labor-intensive but also makes it difficult to maximize the yield and quality of soy milk.

[0004] To address the above problems, this invention proposes a fully automatic soymilk maker. Summary of the Invention

[0005] Based on the existing problems with soybean grinding technology, this invention proposes a fully automatic soybean milk maker.

[0006] This invention proposes a fully automatic soymilk maker, comprising a cabinet, a bean feeding device on the upper surface of the cabinet, a flange fixedly connected to the bottom of the bean feeding hopper of the bean feeding device, a grinding device fixedly connected to the bottom of the flange, a recycling bin on one side of the cabinet, a mixing chamber inside the cabinet, the upper end of the mixing chamber fixedly connected to the inner top wall of the cabinet, one end of the grinding device fixedly connected to the inner wall of the mixing chamber, a steam generator on one side of the mixing chamber, the bottom of the steam generator fixedly connected to the inner bottom wall of the cabinet, a heat-conducting pipe inside the mixing chamber, one end of the heat-conducting pipe penetrating the mixing chamber and fixedly connected to the upper end of the steam generator via a controller, a discharge pipe fixedly connected to the side of the cabinet, the inner wall of the discharge pipe fixedly connected to the inner bottom wall of the mixing chamber, heat dissipation holes on the side of the cabinet, and rollers arranged in an array at the bottom of the cabinet.

The surface of the sliding rod is fixedly connected to the side of two adjacent filter screens. The sliding rod is made of food-grade silicone.

[0011] Preferably, one side of the storage tank is embedded and hung on the inner wall of the cavity. Feeding rollers are arranged in a circular array inside the storage tank. Motor boxes are symmetrically arranged inside the storage tank with respect to the central axis of the cavity. The motor boxes are located between the two feeding rollers. The two sides of the motor boxes are fixedly connected to the inner wall of the cavity and the inner wall of the storage tank, respectively. Two motors with opposite output shafts are arranged inside the motor boxes. The output shafts of the two motors in the motor boxes are fixedly connected to universal joints. The output shaft of one motor box is fixedly connected to one end of the feeding roller through one end of the universal joint. The output shaft of the other motor box is fixedly connected to the bottom end of the material transfer mechanism through one end of the universal joint. The surface of the material transfer mechanism is in contact with one end of the feeding roller.

[0012] Preferably, the rotating device includes a first gear fixed to the lower surface of the lower grinding disc, the lower surface of the first gear being fixedly connected to the end of the coupling of the motor, a second gear meshing with the side of the first gear, circular grooves formed on the upper and lower surfaces of the second gear, steel balls arranged in a circumferential array on the inner walls of the two circular grooves, the steel balls on the upper surface of the second gear being in contact with the lower surface of the lower grinding disc, the steel balls on the lower surface of the second gear being in contact with the upper surface of the support plate, a third gear being provided on one side of the second gear, the side of the third gear being rotatably connected to the side of the second gear, a bearing being embedded in the center of the third gear, the inner ring of the bearing being fixedly connected to the upper surface of the support plate through a limiting post, a fourth gear being rotatably connected to the side of the third gear, the lower surface of the fourth gear having the same design as the lower surface of the second gear, connecting blocks being fixedly connected in a circumferential array on the outer side of the fourth gear, one end of each connecting block being fixedly connected to the upper end of the filter plate.

[0013] Preferably, the material transfer mechanism includes a conveying pipe, which is in the shape of an inverted "L". A conveying roller is provided inside the conveying pipe. The bottom end of the conveying roller is fixedly connected to one end of the universal joint. The adjacent two ends of the conveying roller inside the right angle of the conveying pipe are fixedly connected by the universal joint. The upper end outlet of the conveying pipe is located directly above the drain hole opened on the upper surface of the upper grinding disc.

[0014] Preferably, the cleaning mechanism includes a card block that is slidably connected to the inner wall of the card slot, and a brush is fixedly connected to the lower end of the card block, with one end of the brush in contact with the surface of the filter plate.

[0015] Preferably, the outer surface of the feeding roller is coated with a silicone layer.

[0016] Preferably, the steps of using a fully automatic soymilk maker include the following steps: Step 1: Put the beans into the bean feeding chamber of the bean feeding device. The bean feeding device controls the rotation of the roller shaft connected to the motor through the motor, thereby further controlling the falling speed of the beans. When the beans enter the interior of the cavity through the connecting pipe, the beans enter the groove opened on the upper surface of the lower grinding plate through the leakage hole opened at the center of the upper grinding plate.

[0017] Step 2: The controller controls the motor 38 to rotate. The motor 38 drives the first gear, which is fixedly connected to the coupling, to rotate through the output shaft. The lower grinding disc, which is fixedly connected to the first gear, rotates synchronously. When the lower grinding disc rotates at high speed, it centrifuges the beans inside the groove and sends them out. The centrifuged beans are then crushed by the grinding of the upper and lower grinding discs. The crushed beans leave the space between the lower and upper grinding discs under the high-speed rotation of the lower grinding disc and adhere to the filter plate. At the same time, the rotation of the motor drives the second gear, which meshes with the outer side of the first gear, to rotate. The second gear drives the third gear, which meshes with it, to rotate in the opposite direction. The third gear drives the fourth gear, which is located on the outermost side, to rotate. This further drives the filter plate, which is fixedly connected to the connecting block on the outer side of the fourth gear, to rotate in the opposite direction. The bean residue attached to the surface of the filter plate is cleaned out of the filter plate under the combined action of centrifugal force and the brush and adheres to the inner wall of the cavity. This is the initial filtration of the bean residue.

[0018] Step 3: Filter the ground soybean residue thoroughly. At this time, start the electric telescopic rod. The slide rod fixedly connected to the end of the electric telescopic rod slides upward in the slide groove on the side of the filter plate, driving the filter screen embedded in the annular groove of the filter plate to rise until the top of the filter screen is in contact with the top wall of the annular groove of the filter plate.

[0019] Step 4: The soybean residue adhering to the filter screen surface is removed by the action of the brush. The removed soybean residue is thrown out by the centrifugal motion of the filter plate and adheres to the inner wall of the cavity. The soybean residue adhering to the inner wall of the cavity slides down the inner wall into the storage tank. The two motors in the motor box start at the same time, driving the feeding roller and the conveying roller to rotate respectively. The soybean residue in the storage tank is squeezed by the rotation of the feeding roller to the conveying roller, and then the conveying roller transports the soybean residue to the leakage hole of the upper grinding disc.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. By setting up a rotating device, the lower grinding disc is driven by a motor to grind the beans. At the same time, the filter plate can rotate in the opposite direction to the lower grinding disc, so as to further achieve a filtering effect on the bean residue and soy milk produced by grinding. The bean residue is then thrown off the surface of the filter plate and attached to the cavity.

[0022] 2. By setting up a storage tank, the soybean residue attached to the inner wall of the cavity can be collected. Under the rotation of the feeding roller, the soybean residue at different positions in the storage tank is conveyed and squeezed to the material transfer mechanism.

[0023] 3. By setting up a material conveying mechanism, the soybean residue concentrated in one place is re-entered into the hole of the upper grinding disc through the conveying roller and conveying pipe to achieve the circulation and grinding of soybean residue and improve the yield of soybean pulp.

[0024] 4. By setting up a filter plate, operators can choose between coarsely ground and finely ground soy milk under their control. Coarsely ground soy milk can also provide raw materials for making soy products, while finely ground soy milk can further improve the taste of soy milk. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figures 1-9 An automatic soymilk maker includes a cabinet 1. A bean feeding device 2 is provided on the upper surface of the cabinet 1. A flange is fixedly connected to the bottom of the bean feeding hopper of the bean feeding device 2. A grinding device 3 is fixedly connected to the bottom of the flange. A recycling box 4 is provided on one side of the cabinet 1. A mixing box 5 is provided inside the cabinet 1. The upper end of the mixing box 5 is fixedly connected to the inner top wall of the cabinet 1. One end of the grinding device 3 is fixedly connected to the inner wall of the mixing box 5. A steam generator 6 is provided on one side of the mixing box 5. The bottom of the steam generator 6 is fixedly connected to the inner bottom wall of the cabinet 1. A heat conduction pipe 7 is provided inside the mixing box 5. One end of the heat conduction pipe 7 passes through the body of the mixing box 5 and is fixedly connected to the upper end of the steam generator 6 through a controller. A discharge pipe 8 is fixedly connected to the side of the cabinet 1. The inner wall of the discharge pipe 8 is fixedly connected to the inner bottom wall of the mixing box 5. Heat dissipation holes are provided on the side of the cabinet 1. Rollers 9 are arranged in an array at the bottom of the cabinet 1.

[0037] To achieve the repeated grinding action of the grinding device 3 receiving beans from the bean feeding hopper of the bean feeding device 2, the grinding device 3 includes a connecting pipe 30. A cavity 31 is fixedly connected to the bottom of the connecting pipe 30. An upper grinding disc 32 is disposed inside the cavity 31, and a lower grinding disc 33 is disposed below the upper grinding disc 32. A filter plate 34 is disposed on the outer side of the lower grinding disc 33, and a storage trough 35 is disposed on the outer side of the filter plate 34. A rotating device 36 is disposed below the lower grinding disc 33, and the lower end of the rotating device 36 is fixedly connected to... A support plate 37 is provided, and a motor 38 is provided below the cavity 31. A sealed bearing 39 is embedded in the center of the bottom of the cavity 31. The output shaft of the motor 38 is fixedly connected to the inner ring of the sealed bearing 39 through a coupling, and the coupling at the end of the motor 38 extends into the interior of the cavity 31 and is fixedly connected to the bottom end of the rotating device 36. A connecting pipe 310 is fixedly connected to the side of the cavity 31. A material transfer mechanism 311 is symmetrically fixedly connected to the inner wall of the cavity 31 along the central axis of the cavity 31 in the vertical direction.

[0038] Specifically, this is achieved through a device where both the upper grinding disc 32 and the lower grinding disc 33 are ultra-fine grinding discs. Ultra-fine grinding discs offer higher grinding precision, enabling the production of soy milk with an extremely smooth texture. The automatic, repeated grinding of the soybeans fully releases the nutrients, resulting in a richer and more palatable soy milk. During multiple grinding processes, the particles in the soy milk are further refined, resulting in a smoother and more delicate texture, increased soy milk yield, and improved quality. This process also reduces manual labor and enhances work efficiency.

[0039] A funnel-shaped hole is provided at the center of the upper grinding disc 32. Fixing blocks 321 are arranged in a circular array on the surface of the upper grinding disc 32. One end of the fixing blocks 321 is fixedly connected to the inner wall of the cavity 31. A slot is provided on one side of the upper grinding disc 32. A cleaning mechanism 322 is slidably connected to the inner wall of the slot. The distance between the lower surface of the upper grinding disc 32 and the upper surface of the lower grinding disc 33 is 0.1 mm.

[0040] Specifically, through the above structural design, the soybean residue exiting from the feed mechanism 311 can easily enter the upper grinding disc 32. At the same time, the cleaning mechanism 322 cleans the filter plate 34. After the soybean residue enters the storage tank 35, the feed mechanism 311 further enables the upper grinding disc 32 to fully collect the soybean residue. The increased distance between the lower surface of the upper grinding disc 32 and the upper surface of the lower grinding disc 33 further enhances the grinding of the soybeans.

[0041] The filter plate 34 has an annular groove inside, and filter screens 341 are arranged in a circular array inside the annular groove. The outer surface of the filter plate 34 has a sliding groove arranged in a circular array. The inner wall of the sliding groove is fixedly connected to the inner wall of the annular groove. An electric telescopic rod 342 is fixedly connected to the outer surface of the filter plate 34. A sliding rod 343 is fixedly connected to the top of the electric telescopic rod 342. The surface of the sliding rod 343 is fixedly connected to the side of two adjacent filter screens 341 respectively. The material of the sliding rod 343 is food-grade silicone.

[0042] Specifically, the filter plate 34 is used to finely filter the ground soybean residue. At this time, the electric telescopic rod 342 is activated, and the slide rod 343 fixedly connected to the end of the electric telescopic rod 342 slides upward in the slide groove on the side of the filter plate 34, driving the filter screen 341 embedded in the annular groove of the filter plate 34 to rise until the top of the filter screen 341 is in contact with the top wall of the annular groove of the filter plate 34. Under the control of the operator, it is possible to select coarsely ground soybean milk or finely ground soybean milk. The coarsely ground finished soybean milk can also provide raw materials for making soy products, while the finely ground soybean milk can further improve the taste of the soybean milk.

[0043] One side of the storage tank 35 is embedded and hung on the inner wall of the cavity 31. The storage tank 35 has a feeding roller 353 arranged in a circular array inside. The storage tank 35 has a motor box 351 symmetrically arranged inside the cavity 31 with the central axis of the cavity 31. The motor box 351 is located between the two feeding rollers 353. The two sides of the motor box 351 are fixedly connected to the inner wall of the cavity 31 and the inner wall of the storage tank 35, respectively. The motor box 351 has two motors with output shafts in opposite directions. The output shafts of the two motors in the motor box 351 are fixedly connected to universal joints 352. The output shaft of one motor box 351 is fixedly connected to one end of the feeding roller 353 through one end of the universal joint 352. The output shaft of the other motor box 351 is fixedly connected to the bottom end of the material transfer mechanism 311 through one end of the universal joint 352. The surface of the material transfer mechanism 311 is in contact with one end of the feeding roller 353.

[0044] Specifically, the storage tank 35 is used to collect the soybean residue attached to the inner wall of the cavity 31. Under the rotation of the feeding roller 353, the soybean residue at different positions in the storage tank 35 is conveyed and squeezed to the material transfer mechanism 311.

[0045] The rotating device 36 includes a first gear 361 fixed to the lower surface of the lower grinding disc 33. The lower surface of the first gear 361 is fixedly connected to the end of the coupling of the motor 38. A second gear 362 meshes with the side of the first gear 361. Circular grooves are formed on the upper and lower surfaces of the second gear 362. Steel balls are arranged in a circumferential array on the inner wall of the two circular grooves. The steel balls on the upper surface of the second gear 362 are in contact with the lower surface of the lower grinding disc 33, and the steel balls on the lower surface of the second gear 362 are in contact with the upper surface of the support plate 37. A side of the second gear 362 is provided with... There is a third gear 363, the side of which is rotatably connected to the side of the second gear 362. A bearing is embedded in the center of the third gear 363, and the inner ring of the bearing is fixedly connected to the upper surface of the support plate 37 through a limiting post. A fourth gear 364 is rotatably connected to the side of the third gear 363. The lower surface of the fourth gear 364 adopts the same design as the lower surface of the second gear 362. Connecting blocks are fixedly connected to the outer side of the fourth gear 364 in a circumferential array. One end of each connecting block is fixedly connected to the upper end of the filter plate 34.

[0046] Specifically, this is implemented by using the device, where the motor 38 drives the lower grinding disc 33 to rotate and grind the beans, while also driving the filter plate 34 to rotate in the opposite direction to the lower grinding disc 33, so as to further achieve a filtering effect on the bean residue and soy milk produced by grinding, and then throw the produced bean residue from the surface of the filter plate 34 onto the cavity 31 for adhesion.

[0047] The material conveying mechanism 311 includes a conveying pipe 3111, which is inverted "L" shape. A conveying roller 3112 is provided inside the conveying pipe 3111. The bottom end of the conveying roller 3112 is fixedly connected to one end of the universal joint 352. The adjacent two ends of the conveying roller 3112 inside the right angle of the conveying pipe 3111 are fixedly connected by the universal joint. The upper end outlet of the conveying pipe 3111 is located directly above the leakage hole opened on the upper surface of the upper grinding disc 32.

[0048] Specifically, this mechanism allows the soybean residue, which is concentrated in one place, to be re-entered into the hole of the upper grinding disc 32 through the conveying roller 3112 and the conveying pipe 3111 to achieve cyclic grinding of the soybean residue and improve the yield of soybean pulp.

[0049] The cleaning mechanism 322 includes a card block 3221 that is slidably connected to the inner wall of the card slot. A brush 3222 is fixedly connected to the lower end of the card block 3221, and one end of the brush 3222 is in contact with the surface of the filter plate 34.

[0050] Specifically, this mechanism enables the filter plate 34 to rotate at high speed while the brush 3222 in contact with the surface of the filter plate 34 simultaneously cleans the soybean residue from the surface of the filter plate 34 and the filter holes, thereby improving the effect of the soybean residue being thrown out when the filter plate 34 rotates at high speed and preventing a small amount of soybean residue from adhering to the surface of the filter plate 34.

[0051] The outer surface of the feed roller 353 is coated with a silicone layer.

[0052] Specifically, through the above structural design, direct contact between the soybean residue in the storage tank 35 and the feeding roller 353 is effectively avoided, further improving food safety.

[0053] Reference Figures 1-9 The steps for using a fully automatic soymilk maker are as follows: Step 1: Put the beans into the bean feeding chamber of the bean feeding device 2. The bean feeding device 2 controls the rotation of the roller shaft connected to the motor through the motor, thereby further controlling the falling speed of the beans. When the beans enter the interior of the cavity 31 through the connecting pipe 30, the beans enter the groove on the upper surface of the lower grinding plate 33 through the leakage hole opened at the center of the upper grinding plate 32.

[0054] Step 2: The controller controls the motor 38 to rotate. The motor 38 drives the first gear 361, which is fixedly connected to the coupling, to rotate via its output shaft. The lower grinding disc 33, which is fixedly connected to the first gear 361, rotates synchronously. Under high-speed rotation, the lower grinding disc 33 centrifuges the beans inside the groove. The centrifuged beans are then pulverized by the grinding action of the upper grinding disc 32 and the lower grinding disc 33. The pulverized beans, under the high-speed rotation of the lower grinding disc 33, leave the space between the lower grinding disc 33 and the upper grinding disc 32 and adhere to the filter plate 34. Simultaneously, the motor 38... The rotation drives the second gear 362, which meshes with the outer side of the first gear 361, to rotate. The second gear 362 drives the third gear 363, which meshes with it, to rotate in the opposite direction. The third gear 363 drives the fourth gear 364, which is located on the outermost side, to rotate. This further drives the filter plate 34, which is fixedly connected to the connecting block on the outer side of the fourth gear 364, to rotate in the opposite direction. The soybean residue attached to the surface of the filter plate 34 is cleaned out of the filter plate 34 under the dual action of centrifugal force and brush 3222 and adheres to the inner wall of the cavity 31. This is the initial filtration of the soybean residue.

[0055] Step 3: Filter the ground soybean residue thoroughly. At this time, start the electric telescopic rod 342. The slide rod 343, which is fixedly connected to the end of the electric telescopic rod 342, slides upward in the slide groove on the side of the filter plate 34, driving the filter screen 341 embedded in the annular groove of the filter plate 34 to rise until the top of the filter screen 341 is in contact with the top wall of the annular groove of the filter plate 34.

[0056] Step 4: The soybean residue attached to the surface of the filter screen 341 is removed by the action of the brush 3222. The removed soybean residue is thrown out by the centrifugal motion of the filter plate 34 and attached to the inner wall of the cavity 31. The soybean residue attached to the inner wall of the cavity 31 slides down the inner wall into the storage tank 35. The two motors in the motor box 351 start at the same time, driving the feeding roller 353 and the conveying roller 3112 to rotate respectively. The soybean residue in the storage tank 35 is squeezed by the rotation of the feeding roller 353 to the conveying roller 3112, and then the conveying roller 3112 transports the soybean residue to the leakage hole of the upper grinding disc 32.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

8. The method of using a fully automatic soymilk maker according to any one of claims 1-7, characterized in that: Includes the following steps: Step 1: Place the beans into the bean inlet of the bean feeding device (2). The bean feeding device (2) controls the rotation of the roller connected to the motor through the motor to further control the falling speed of the beans. When the beans enter the cavity (31) through the connecting pipe (30), the beans enter the groove on the upper surface of the lower grinding disc (33) through the hole opened at the center of the upper grinding disc (32). Step 2: Control the motor (38) to rotate via the controller. The motor (38) drives the first gear (361) fixedly connected to the coupling to rotate via the output shaft. The lower grinding disc (33) fixedly connected to the first gear (361) rotates synchronously. Under high-speed rotation, the lower grinding disc (33) centrifuges the beans inside the groove. The centrifuged beans are crushed by the grinding of the upper grinding disc (32) and the lower grinding disc (33). After crushing, the beans leave the space between the lower grinding disc (33) and the upper grinding disc (32) under the high-speed rotation of the lower grinding disc (33) and adhere to the filter plate (34). At the same time, the motor (38) rotates simultaneously. The rotation of the first gear (361) drives the second gear (362) meshing with the outer side of the first gear (361) to rotate. The second gear (362) drives the third gear (363) meshing with it to rotate in the opposite direction. The third gear (363) drives the fourth gear (364) located on the outermost side to rotate, thereby further driving the filter plate (34) fixedly connected to the connecting block on the outer side of the fourth gear (364) to rotate in the opposite direction. The soybean residue attached to the surface of the filter plate (34) is cleaned out of the filter plate (34) under the dual action of centrifugal force and brush (3222) and attached to the inner wall of the cavity (31). At this time, the soybean residue is initially filtered. Step 3: Filter the ground soybean residue thoroughly. At this time, start the electric telescopic rod (342). The slide rod (343) fixedly connected to the end of the electric telescopic rod (342) slides upward in the slide groove on the side of the filter plate (34), which drives the filter screen (341) embedded in the annular groove of the filter plate (34) to rise until the top of the filter screen (341) is in contact with the top wall of the annular groove of the filter plate (34). Step 4: The soybean residue attached to the surface of the filter screen (341) is removed by the action of the brush (3222). The removed soybean residue is thrown out by the centrifugal motion of the filter plate (34) and attached to the inner wall of the cavity (31). The soybean residue attached to the inner wall of the cavity (31) slides down the inner wall to the storage tank (35). The two motors in the motor box (351) start at the same time, driving the feeding roller (353) and the conveying roller (3112) to rotate respectively. The soybean residue in the storage tank (35) is squeezed by the rotation of the feeding roller (353) to the conveying roller (3112), and then the conveying roller (3112) transports the soybean residue to the hole of the upper grinding disc (32).
