Description

Technical Field

[0001] This invention relates to the field of food grinding technology, specifically to a grinding device for food processing. Background Technology

[0002] The food processing industry has a long history of development. The food industry refers to an industrial system that mainly uses products or semi-finished products from agriculture, fishery, animal husbandry, forestry or chemical industry as raw materials to manufacture, extract and process into food or semi-finished products. It has continuous and organized economic activities. In daily production and life, we often need a variety of powdered foods or food raw materials. Grinding operations are often involved in food processing, and grinding machines are usually used for grinding operations.

[0003] Now, with the development of the times, traditional stone mills are gradually being phased out, and machines are often used to process food. Current devices use machines to drive stone mills to grind food. Although they can crush and refine food, the degree of fineness of crushing cannot be flexibly and automatically adjusted. Some food may not be crushed thoroughly, and inevitably a few pieces of food will not be ground properly. These unground foods mixed in with food powder may affect subsequent processing. To solve this problem, we propose a grinding device for food processing. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for food processing, comprising: a body, a feeding hopper fixedly installed on the top of the body, the bottom of the feeding hopper penetrating the body and extending into the interior of the body, and a grinder fixedly installed on the bottom of the feeding hopper; a filter slidably connected inside the body, the filter being located directly below the grinder; a first motor fixedly installed on the outer surface of the body, the output end of the first motor penetrating the body and fixedly connected to a roller, the roller being rotatably connected between opposite surfaces inside the body; a conveyor belt sleeved on the outer surface of the roller, a collector fixedly installed on the outer surface of the conveyor belt; and a ramp fixedly connected to the bottom of the body. This device can grind food and filter and classify the ground food, only discharging the ground food.

[0005] Preferably, the bottom of the machine body is fixedly connected to a shell leg, the outer surface of the machine body is fixedly installed with a controller, and the bottom of the machine body near the conveyor belt is fixedly installed with a discharge port. The discharge port passes through the machine body and is fixedly connected to the bottom of the slope. The operation of the device can be controlled by the controller, and the ground food is sent to the outside through the discharge port.

[0006] Preferably, the grinder includes a grinding shell, which is fixedly connected to the bottom of the feed hopper. A recovery port is fixedly installed on the top of the outer surface of the grinding shell. A fixing plate is fixedly connected inside the grinding shell. A motor box is fixedly connected to the bottom of the fixing plate. A second motor is fixedly connected to the top of the inner cavity of the motor box. The output end of the second motor passes through the motor box and is fixedly mounted with a rotating rod. A cutting blade is fixedly connected to the top of the rotating rod. An upper grinding disc is fixedly connected to the bottom of the rotating rod. A lower grinding disc is fixedly installed at the bottom of the grinding shell. The lower grinding disc is located directly below the upper grinding disc. Food enters the grinding shell through the feed hopper, falls between the upper and lower grinding discs, and is ground by the upper and lower grinding discs.

[0007] Preferably, the upper grinding disc includes an elastic rod, which is fixedly connected to the bottom of the rotating rod. An upper grinding disc shell is fixedly connected to the outer surface of the elastic rod. A straight plate is fixedly connected to the inner cavity of the upper grinding disc shell. There are several straight plates, and an inclined body is fixedly installed between every two straight plates. A ball is provided on the upper surface of the inclined body. The ball and the inclined body roll and adapt to each other. The ball and the inclined body cooperate to convert centrifugal force into downward pressure, thereby increasing the fineness of the grinding.

[0008] Preferably, a grinding column is fixedly installed at the bottom of the upper grinding disc shell. There are several grinding columns, and a grinding tooth is fixedly installed between every two grinding columns. The grinding column has a certain tilt angle. When the grinding column rotates, it exerts an outward force on the food, guiding the food to move outward. The grinding tooth cooperates with the upper grinding disc shell to grind the food.

[0009] Preferably, the lower grinding disc includes a lower grinding disc housing, which is fixedly installed at the bottom of the grinding housing. A steep slope is fixedly connected to the center of the top of the lower grinding disc housing, and guide plates are provided around the steep slope. The bottom of the guide plates is fixedly connected to the top of the lower grinding disc housing. The steep slope has a certain height, and food falling onto the surface of the steep slope will slide to the sides and enter the gaps between the guide plates.

[0010] Preferably, the recycling port includes a recycling plate, which is fixedly installed on the top of the outer surface of the grinding shell. An inclined plate is fixedly connected to the bottom of the recycling plate, and a baffle tooth is fixedly connected to the top of the recycling plate. The baffle tooth and the inclined plate cooperate to send the food from the recycling device into the interior of the grinding shell.

[0011] Preferably, the filter includes a slide rail, which is fixedly connected to the inside of the machine body. A base plate is slidably connected to the surface of the slide rail, and a first filter plate and a second filter plate are slidably connected to the surface of the base plate. The second filter plate is located directly above the first filter plate. The surface of the first filter plate has a number of first filter holes, and the surface of the second filter plate has a number of second filter holes. The first filter plate and the second filter plate can work together to filter food of different sizes.

[0012] Preferably, the recycler includes a horizontal plate and a fixed column, both of which are fixedly connected to the outer surface of the conveyor belt. The fixed column is located above the horizontal plate, and a rotating plate is rotatably connected to the fixed column via a rotating rod. A baffle is fixedly connected to the top of the rotating plate, and a spring is fixedly connected to the bottom of the rotating plate. The other end of the spring is fixedly connected to the top of the horizontal plate. The rotating plate and the baffle work together to send food that falls onto the surface of the rotating plate back into the grinding shell.

[0013] This invention provides a grinding apparatus for food processing. It has the following beneficial effects:

[0014] 1. This food processing grinding device controls the fineness of the food through the upper grinding disc. After the motor drives the upper grinding disc to rotate, the ball will be subjected to a centrifugal force. The ball and the inclined body cooperate to convert the centrifugal force into downward pressure. The higher the power of the second motor, the greater the downward pressure of the upper grinding disc, and the finer the food grinding.

[0015] 2. The grinding device for food processing can control the fineness of food filtration by adjusting the positions of the first filter plate and the second filter plate. The first filter hole and the second filter hole are square of the same size. By adjusting the positions of the first filter plate and the second filter plate, the overlapping part of the first filter hole and the second filter hole can be changed, which can be changed according to the gap size of the food.

[0016] Third, this food processing grinding device can re-grind unground food through a collector. The unground food falls through a filter onto the surface of the rotating plate, and the conveyor belt then sends the collector to the top of the grinder.

[0017] IV. This food processing grinding device, through the cooperation of the recovery port and the recovery device, sends the unground food into the grinding shell. The baffle presses down on the rotating plate, the rotating plate rotates downward, the spring is compressed, and the food slides down the rotating plate and the inclined plate into the grinding shell.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] like Figures 1-9 As shown, the present invention provides a technical solution: a grinding device for food processing, comprising: a body 1, a feeding hopper 4 fixedly installed on the top of the body 1, the bottom of the feeding hopper 4 penetrating the body 1 and extending into the interior of the body 1, and a grinder 5 fixedly installed on the bottom of the feeding hopper 4; a filter 6 slidably connected inside the body 1, and the filter 6 being located directly below the grinder 5; a first motor 7 fixedly installed on the outer surface of the body 1, the output end of the first motor 7 penetrating the body 1 and fixedly connected to a roller 8, the roller 8 being rotatably connected between opposite surfaces inside the body 1; a conveyor belt 10 sleeved on the outer surface of the roller 8, a collector 9 fixedly installed on the outer surface of the conveyor belt 10; and a ramp 12 fixedly connected to the bottom of the body 1. Food enters the grinder 5 through the feeding hopper 4, and after grinding, falls onto the surface of the filter 6. The ground food is filtered by the pre-adjusted filter 6, and the unground food falls along the surface of the filter 6 to the top of the collector 9 and is sent back into the grinding shell 51.

[0030] The bottom of the machine body 1 is fixedly connected to the shell leg 2, and the outer surface of the machine body 1 is fixedly installed with the controller 3. The bottom of the machine body 1 near the conveyor belt 10 is fixedly installed with the discharge port 11. The discharge port 11 passes through the machine body 1 and is fixedly connected to the bottom of the slope 12. The ground food slides out of the discharge port 11 along the slope 12 to the outside.

[0031] The grinder 5 includes a grinding shell 51, which is fixedly connected to the bottom of the feed hopper 4. A recovery port 52 is fixedly installed on the top of the outer surface of the grinding shell 51. A fixing plate 53 is fixedly connected inside the grinding shell 51. A motor box 54 is fixedly connected to the bottom of the fixing plate 53. A second motor 55 is fixedly connected to the top of the inner cavity of the motor box 54. The output end of the second motor 55 passes through the motor box 54 and is fixedly installed with a rotating rod 56. A cutting blade 57 is fixedly connected to the top of the rotating rod 56. An upper grinding disc 58 is fixedly connected to the bottom of the rotating rod 56. A lower grinding disc 59 is fixedly installed at the bottom of the grinding shell 51. The lower grinding disc 59 is located directly below the upper grinding disc 58. When food enters the grinding shell 51, the second motor 55 starts working, driving the rotating rod 56 to rotate. The rotating rod 56 drives the cutting blade 57 and the upper grinding disc 58 to rotate. The cutting blade 57 breaks down the main structure of the food, and then the upper grinding disc 58 and the lower grinding disc 59 work together to grind the food.

[0032] The upper grinding disc 58 includes an elastic rod 581, which is fixedly connected to the bottom of the rotating rod 56. The outer surface of the elastic rod 581 is fixedly connected to the upper grinding disc housing 582. The inner cavity of the upper grinding disc housing 582 is fixedly connected to a straight plate 583. There are several straight plates 583, and an inclined body 584 is fixedly installed between every two straight plates 583. A ball 585 is provided on the upper surface of the inclined body 584. The ball 585 rolls and adapts to the inclined body 584. The rotating rod 56 drives the elastic rod 581 and the upper grinding disc housing 582 to rotate. The rotation of the upper grinding disc housing 582 exerts a centrifugal force on the ball 585, which is converted into downward pressure.

[0033] Grinding columns 586 are fixedly installed at the bottom of the upper grinding disc shell 582. There are several grinding columns 586, and grinding teeth 587 are fixedly installed between every two grinding columns 586. The grinding columns 586 can guide the movement trajectory of the food by rotating and cooperating with the lower grinding disc 59.

[0034] The lower grinding disc 59 includes a lower grinding disc housing 591, which is fixedly installed at the bottom of the grinding housing 51. A steep slope 592 is fixedly connected to the center of the top of the lower grinding disc housing 591. Guide plates 593 are arranged around the steep slope 592. The bottom of the guide plates 593 is fixedly connected to the top of the lower grinding disc housing 591. The guide plates 593 gradually become narrower and shallower from the inside to the outside, so that the food is gradually ground more finely on the top of the lower grinding disc housing 591.

[0035] The recycling port 52 includes a recycling plate 521, which is fixedly installed on the top of the outer surface of the grinding shell 51. A sloping plate 522 is fixedly connected to the bottom of the recycling plate 521, and a baffle 523 is fixedly connected to the top of the recycling plate 521. The baffle 523 presses down on the rotating plate 93, and the food slides into the interior of the grinding shell 51 through the sloping plate 522.

[0036] The filter 6 includes a slide rail 61, which is fixedly connected to the inside of the body 1. A base plate 62 is slidably connected to the surface of the slide rail 61. A first filter plate 63 and a second filter plate 65 are slidably connected to the surface of the base plate 62, with the second filter plate 65 located directly above the first filter plate 63. The surface of the first filter plate 63 has a number of first filter holes 64, and the surface of the second filter plate 65 has a number of second filter holes 66. The first filter holes 64 and the second filter holes 66 are square and the same size. By adjusting the first filter plate 63 and the second filter plate 65, the overlapping part of the first filter holes 64 and the second filter holes 66 changes, and the fineness of the food that the filter 6 can filter also changes accordingly.

[0037] The collector 9 includes a horizontal plate 91 and a fixed column 92. Both the horizontal plate 91 and the fixed column 92 are fixedly connected to the outer surface of the conveyor belt 10, and the fixed column 92 is located above the horizontal plate 91. The fixed column 92 is rotatably connected to a rotating plate 93 via a rotating rod. A baffle 94 is fixedly connected to the top of the rotating plate 93, and a spring 95 is fixedly connected to the bottom of the rotating plate 93. The other end of the spring 95 is fixedly connected to the top of the horizontal plate 91. Unground food falls into the surface of the rotating plate 93. The conveyor belt 10 drives the fixed column 92 and the rotating plate 93 to the top of the grinding shell 51, and then cooperates with the collection port 52 to send the food back into the grinding shell 51.

[0038] In use, food is fed into the device through the feed hopper 4. The food falls into the grinder 5 through the feed hopper 4. It is first cut by the cutting blade 57, which initially breaks down the main structure of the food. Then, it falls through the elastic rod 581 to the middle of the upper grinding disc 58 and the lower grinding disc 59. The steep slope 592 guides the food to scatter in all directions. The fixed plate 53 drives the rotating rod 56 and the upper grinding disc 58 to rotate. The rotation of the upper grinding disc 58 causes the grinding column 586 to exert an outward force on the food. In conjunction with the guide plate 593, the food is gradually guided outward. The food being ground falls downwards onto the upper surface of the filter 6. Through the cooperation of the first filter plate 63 and the second filter plate 65, the food is filtered. Food that does not meet the requirements slides along the filter 6 toward the collector 9 and falls onto the upper surface of the rotating plate 93. It is then conveyed by the conveyor belt 10 to the top of the grinding shell 51. After passing through the collection port 52, it falls back into the grinding shell 51 for secondary grinding. Food that meets the requirements can pass through the filter 6 and fall onto the upper surface of the ramp 12. It then slides along the ramp 12 toward the discharge port 11.

[0039] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
