Description
Technical Field
[0001] This utility model belongs to the technical field of sesame oil production equipment, specifically a low-temperature grinding machine for stone mill sesame oil production. Background Technology
[0002] With the development of society, low-temperature grinding mills are often needed in other fields such as food, medicine, cosmetics, and chemicals. A low-temperature grinding mill is a device that uses a low-temperature environment to grind materials.
[0003] Stone-ground sesame oil production often requires the use of low-temperature grinding machines. Sesame seeds are rich in nutrients, such as unsaturated fatty acids, vitamin E, and sesamin. Low-temperature grinding can avoid the destruction of these nutrients by high temperatures, thus preserving the nutritional value of sesame seeds to the maximum extent and giving the sesame oil higher health benefits.
[0004] In existing technologies, long-term observation has revealed that existing low-temperature grinders typically require air cooling of sesame seeds before grinding. When sesame seeds are cooled by air, the surface temperature drops rapidly, and moisture in the surrounding environment condenses into small water droplets on the sesame seed surface, resulting in a damp surface. Damp sesame seeds tend to clump together during grinding, causing uneven grinding. Some parts are over-ground while others are under-ground, ultimately leading to uneven particle size of the sesame powder and affecting product quality. Therefore, a low-temperature grinder for stone mill sesame oil production is proposed to address these issues. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] Please see Figures 1-4This utility model provides a low-temperature grinding machine for stone mill sesame oil production, including a workbench 1; a lower grinding disc 10 is provided at the top of the workbench 1; an upper grinding disc 11 is provided at the top of the lower grinding disc 10; a first connecting rod 12 is symmetrically fixed to the top of the upper grinding disc 11; a storage tank 13 is fixed to the side wall of the first connecting rod 12; a cover 14 is provided at the top of the storage tank 13; a filling port 15 is opened at the top of the cover 14; an installation groove 16 is opened on the side wall of the storage tank 13; multiple sets of heating rods 17 are fixed to the inner side of the installation groove 16; a second connecting rod 18 is symmetrically fixed to the top of the cover 14; a servo motor is fixed to the side wall of the second connecting rod 18. 19; The output end of the servo motor 19 is fixedly connected to a rotating shaft 110; Multiple sets of stirring rods 111 are fixedly connected to the side wall of the rotating shaft 110; A guide port 112 is opened on the side wall of the storage tank 13; A feed valve 113 is rotatably installed on the side wall of the guide port 112; A discharge port 114 is opened on the side wall of the lower grinding disc 10; During operation, the workbench 1 can support the lower grinding disc 10, the lower grinding disc 10 can support the upper grinding disc 11, the upper grinding disc 11 can support the first connecting rod 12, the first connecting rod 12 can support the storage tank 13, the cover 14 can support the second connecting rod 18, and the second connecting rod 18 can support the servo motor 19. When the operator... When processing sesame oil, the worker adds the material through the filling port 15. If the surface of the material is found to be slightly damp, the heating rod 17 is supported by the mounting groove 16. The operation of the heating rod 17 raises the temperature inside the storage tank 13. Then, the servo motor 19 drives the rotating shaft 110 to rotate, which in turn drives the stirring rod 111 to stir the material in the storage tank 13, thus ensuring that the material in the storage tank 13 is dried evenly. After drying, once the material has cooled for a period of time, the feeding valve 113 is opened, allowing the material to be guided through the guide port 112 to start the process. The drive assembly drives the upper grinding disc 11 to rotate relative to the lower grinding disc 10, grinding the sesame seeds. The ground sesame paste is discharged through the discharge port 114 at the edge of the lower grinding disc 10, which can be collected for subsequent sesame oil extraction. This design is not only simple and convenient to operate, but also allows the surface of the sesame seeds to be dried before grinding. This reduces the feeding difficulties caused by the strong adhesion of damp sesame seeds, ensuring smooth and stable feeding and maintaining grinding efficiency. At the same time, drying reduces the risk of microbial growth and reduces the acceleration of oil oxidation by microbial metabolism, which is conducive to better preservation of sesame nutrition and flavor during low-temperature grinding, further improving the quality of stone-ground sesame oil and enhancing processing quality.
[0026] Furthermore, such as Figures 1-4As shown, the storage bin 13 has a guide rail 2 on its side wall; a sliding rod 21 is slidably connected to the side wall of the guide rail 2; a connecting frame 22 is fixedly connected to the side wall of the sliding rod 21; and insulation cotton 23 is fixedly connected to the side wall of the connecting frame 22. During operation, when drying the material, the operator pulls the sliding rod 21 to move it along the guide rail 2, which causes the connecting frame 22 to move the insulation cotton 23, thereby wrapping the insulation cotton 23 around the outside of the storage bin 13 and achieving a heat preservation effect. This design can keep the outside of the storage bin 13 warm when drying the material, thereby reducing heat loss and minimizing resource consumption.
[0027] Furthermore, such as Figures 1-4 As shown, a first support plate 3 is symmetrically fixed to the side wall of the storage bin 13; a second support plate 31 is symmetrically fixed to the side wall of the cover 14; an installation hole 32 is provided on the side wall of the second support plate 31; a fixing bolt 33 is provided on the inner side of the installation hole 32; a fixing nut 34 is provided in the middle of the fixing bolt 33; the fixing nut 34 and the fixing bolt 33 are connected by a thread; a sealing ring 35 is fixed to the side wall of the cover 14; during operation, the first support plate 3 and the second support plate 31 provide support. The operator inserts the fixing bolt 33 into the installation hole 32, then puts the fixing nut 34 on the fixing bolt 33 and rotates it to install the cover 14. After installation, the sealing ring 35 improves the sealing performance. This design facilitates the installation and disassembly of the cover 14, making it easier for the operator to clean the inside of the storage bin 13 later.
[0028] Furthermore, such as Figures 1-4 As shown, a third support plate 4 is fixedly connected to the side wall of the workbench 1; a limiting groove 41 is formed on the side wall of the third support plate 4; a receiving bucket 42 is provided inside the limiting groove 41; during operation, the third support plate 4 provides support, the receiving bucket 42 collects the material discharged from the outlet 114, and the limiting groove 41 limits the receiving bucket 42. This design limits the receiving bucket 42, thereby improving the stability of the receiving bucket 42 when collecting materials.
[0029] Furthermore, such as Figures 1-4 As shown, a mounting rod 5 is fixedly connected to the side wall of the workbench 1; a limiting cylinder 51 is fixedly connected to the side wall of the mounting rod 5; the limiting cylinder 51 is inclined; during operation, the mounting rod 5 can support the limiting cylinder 51, and the limiting cylinder 51 can play a guiding and limiting role. This design can play a guiding and limiting role, thereby making the discharged material more concentrated.
[0030] Furthermore, such as Figures 1-4 As shown, the bottom of the workbench 1 is fixed with multiple sets of support legs 6; the bottom of the support legs 6 is fixed with rubber pads 61; during operation, the support legs 6 can support the rubber pads 61, and the rubber pads 61 can increase the friction with the ground.

If the surface of the material is found to be damp, the mounting groove 16 supports the heating rod 17, which then operates. This raises the temperature inside the storage bin 13. Then, the servo motor 19 rotates, driving the rotating shaft 110 to rotate. The rotating shaft 110 then drives the stirring rod 111 to stir the material in the storage bin 13, ensuring the material is dried evenly. After drying, once the material has cooled for a period of time, the feed valve 113 is opened, allowing the material to be guided through the guide port 112. The drive assembly is then activated, driving the upper grinding disc 11 to rotate relative to the lower grinding disc 10. The sesame seeds are ground, and the resulting sesame paste is discharged through the outlet 114 on the edge of the lower grinding disc 10. This paste can be collected for subsequent sesame oil extraction. When drying the material, the operator pulls the slide bar 21 to move it along the guide rail 2, which in turn moves the connecting frame 22 to move the insulation cotton 23. This wraps the insulation cotton 23 around the outside of the storage bin 13, providing insulation. The first support plate 3 and the second support plate 31 provide support. The operator inserts the fixing bolt 33 into the mounting hole 32, and then... The fixing nut 34 is placed on the fixing bolt 33 and rotated to install the cover 14. After installation, the sealing ring 35 improves the sealing performance, the third support plate 4 provides support, the receiving bucket 42 collects the material discharged from the outlet 114, the limiting groove 41 limits the receiving bucket 42, the mounting rod 5 supports the limiting cylinder 51, the limiting cylinder 51 serves as a guide and limiter, the support leg 6 supports the rubber pad 61, and the rubber pad 61 increases the friction with the ground.
