Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a plant grinding and processing device for the production of condiments. Background Technology

[0002] With the ever-accelerating pace of work and life, families where both spouses work have less and less time to cook. After get off work, preparing a nutritious and delicious meal in the shortest amount of time has become a major desire for those who cook at home. On the other hand, with the influx of foreign fast-food chains, the modernization of kitchens in Chinese restaurants, such as hot pot restaurants, must be accelerated. This development of different types of catering businesses has driven the consumption of various types of compound seasonings.

[0003] Seasonings are supplementary food products that enhance the color, aroma, and flavor of dishes, stimulate appetite, and are beneficial to human health. Among them, plant-based seasonings require grinding equipment during production to grind plant seeds, buds, fruits, flowers, bark, and roots into small particles.

[0004] Existing seasoning plant material grinding equipment typically employs high-speed rotary crushing and grinding. During this process, the plant materials are rapidly rotated and ground, repeatedly colliding with the grinding components. This quickly accelerates the rise in internal temperature, causing the seasoning powder to easily develop off-flavors or unpleasant tastes, thus affecting the final flavor and texture of the finished product. For example, the duration of spiciness in chili powder is a crucial factor in determining product quality. Traditional chili powder production often uses the aforementioned high-temperature grinding method. While this method allows for rapid processing, it results in the loss of significant amounts of aroma and spiciness components, as well as minerals and vitamins in the chili peppers, leading to a poor product taste. Summary of the Invention

[0005] This invention provides a plant grinding and processing device for condiment production, which can solve the problem in the prior art where high-speed rotating crushing grinding methods cause the internal temperature of the grinder to rise, and the seasoning powder is prone to producing off-flavors or unpleasant tastes after being heated, thus affecting the final flavor and taste of the seasoning powder product.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a plant grinding and processing device for condiment production, comprising: Grinding box; A grinding mechanism, comprising: an annular screen disposed inside a grinding chamber; a rotating shaft rotatably connected to the grinding chamber, the central axis of the rotating shaft coinciding with the central axis of the annular screen; a connecting plate fixedly connected to the rotating shaft; a crushing plate fixedly connected to the connecting plate; and a first driving unit, the rotating shaft being fixedly connected to the output end of the first driving unit. The cooling mechanism includes a cooling chamber located inside the rotating shaft, connecting plate, and crushing plate. The cooling chamber is used to fill a cooling medium, which is water or cooling oil.

[0007] Preferably, the cooling mechanism further includes hollow fan blades, which are mounted on a rotating shaft and communicate with the cooling cavity.

[0008] Preferably, the cooling mechanism further includes a plurality of hollow protrusions disposed on the working surface of the crushing plate, the interior of the protrusions communicating with the cooling cavity.

[0009] Preferably, an air filter is provided on the side wall of the grinding box, and two cleaning brushes are provided on the rotating shaft, with the two cleaning brushes arranged opposite each other on both sides of the air filter.

[0010] Preferably, the annular screen includes a lower arc-shaped plate and an upper arc-shaped filter screen. The lower arc-shaped plate is sealed and fixedly connected to the inner wall of the grinding box, and the upper arc-shaped filter screen is connected to the upper opening of the lower arc-shaped plate.

[0011] Preferably, the upper arc-shaped filter screen is provided with arc-shaped guide plates at both ends, and the lower arc-shaped plate is provided with arc-shaped guide grooves at both ends. The arc-shaped guide plates are slidably connected to the arc-shaped guide grooves on the same side. The arc-shaped guide groove on the right side is provided with a first elastic element, which is a spring. The inner wall of the arc-shaped guide plate on the right side is provided with an elastic metal sheet, which is made of stainless steel.

[0012] Preferably, a second elastic element, which is a spring, is provided inside the arc-shaped guide groove on the left side.

[0013] Preferably, the system also includes a collection tank, the inside of which is provided a filter cylinder. The upper and lower ends of the filter cylinder are sealed to the collection tank. An air outlet pipe for air discharge is provided on the side wall of the collection tank. A collection pipe extending from the upper end of the grinding box into the filter cylinder is provided at the upper end of the grinding box.

[0014] Preferably, the lower end of the collection tank is provided with a discharge pipe, and a second driving part is provided on the outer wall of the discharge pipe. The output end of the second driving part is provided with a plurality of discharge plates located inside the discharge pipe.

[0015] Preferably, it also includes a feeding mechanism, which includes a screw conveyor connected to the rotary shaft for speed reduction and a feeding cylinder fixedly connected to the side wall of the grinding box. The screw conveyor is rotatably connected inside the feeding cylinder, and a feeding hopper is provided on the feeding cylinder.

[0016] Compared to existing technologies, this invention utilizes a combination of a grinding chamber, an annular screen, a rotating shaft, a connecting plate, a crushing plate, a first driving unit, and a cooling chamber. The first driving unit drives the connecting plate to rotate via the rotating shaft, which in turn drives the crushing plate to rotate. While the crushing plate crushes and grinds the plant materials, it also drives the airflow within the grinding chamber. In addition, the cooling medium circulates within the cooling chamber, allowing the heat generated during the grinding process to be transferred from the crushing plate to the cooling medium. This ensures that the plant materials are ground at a low temperature. After grinding, the seasoning powder that meets the particle size requirements passes through the annular screen and enters the grinding chamber, separating from the plant materials. This prevents the seasoning powder from developing off-flavors or unpleasant tastes after being heated, thus improving the final flavor and texture of the seasoning powder product.

[0019] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1 to 6 As shown, a plant grinding and processing apparatus for condiment production includes: Grinding box 1; The grinding mechanism includes: an annular screen, which is disposed inside the grinding box 1; a rotating shaft 2, which is rotatably connected to the grinding box 1, and the central axis of the rotating shaft 2 coincides with the central axis of the annular screen; a connecting plate 3, which is fixedly connected to the rotating shaft 2; a crushing plate 4, which is fixedly connected to the connecting plate 3; and a first driving unit 6, which is fixedly connected to the output end of the rotating shaft 2. The cooling mechanism includes a cooling chamber 8 located inside the rotating shaft 2, the connecting plate 3, and the breaking plate 4. The cooling chamber 8 is used to fill the cooling medium, which is water or cooling oil.

[0021] In practical use, the first drive unit 6 drives the connecting plate 3 to rotate via the rotating shaft 2. The connecting plate 3 drives the crushing plate 4 to rotate. While the crushing plate 4 crushes and grinds the plant raw materials, it also drives the air flow in the grinding box 1. In addition, the cooling medium circulates inside the cooling chamber 8, so that the heat generated during the grinding process is transferred from the crushing plate 4 to the cooling medium, allowing the plant raw materials to be ground at a low temperature. After grinding, the seasoning powder that meets the particle size requirements enters the grinding box 1 through the annular screen and is separated from the plant raw materials.

[0022] To achieve the purpose of low-temperature grinding, preferably, the cooling mechanism also includes a hollow fan blade 7, which is mounted on the rotating shaft 2. The interior of the fan blade 7 is connected to the cooling chamber 8, and a protective cover is provided on the exterior of the fan blade 7.

[0023] Specifically, during the grinding process, the rotating shaft 2 drives the fan blades 7 to rotate. The rotation of the fan blades 7 introduces cold air into the grinding chamber 1, which cools the crushing plate 4 and the plant materials. The cooling medium circulates inside the cooling chamber. The heat generated during the grinding process is transferred from the crushing plate 4 to the cooling medium, which then transfers the heat to the fan blades 7, which are in contact with the outside air. The rotation of the fan blades 7 accelerates the heat dissipation of the cooling medium, allowing the heat inside the grinding chamber 1 to be quickly dissipated into the outside air. This allows the plant materials to be ground at a low temperature. After grinding, the seasoning powder that meets the particle size requirements will pass through the annular screen under the wind force of the fan blades 7 and enter the grinding chamber 1 to separate from the plant materials. This prevents the seasoning powder from producing off-flavors or unpleasant tastes after being heated, which is beneficial to improving the final flavor and taste of the seasoning powder product. In addition, the protective cover prevents workers from touching the fan blades 7, improving the safety of use.

[0024] To achieve the purpose of low-temperature grinding, preferably, the cooling mechanism also includes a plurality of hollow protrusions 5 disposed on the working surface of the crushing plate 4, the interior of the protrusions 5 being in communication with the cooling chamber 8.

[0025] Specifically, the protrusion 5 is spherical or strip-shaped. On the one hand, the protrusion 5 can increase the shearing force and improve the grinding effect; on the other hand, it can increase the contact area with plant materials and cooling medium, accelerate heat transfer, and improve the cooling effect.

[0026] To achieve the purpose of low-temperature grinding, preferably, an air filter 23 is provided on the side wall of the grinding chamber 1, and two cleaning brushes 24 are provided on the rotating shaft 2, with the two cleaning brushes 24 arranged opposite each other on both sides of the air filter 23.

[0027] Specifically, during the grinding process, the air filter 23 filters the air entering the grinding chamber 1 to prevent dust in the air from mixing with the seasoning powder. The cleaning brush 24 on the outside of the grinding chamber 1 promptly scrapes off the dust filtered by the air filter 23, while the cleaning brush 24 on the inside of the grinding chamber 1 promptly scrapes off the seasoning powder that falls on the inside of the air filter 23, so that the air filter 23 remains breathable, improves ventilation capacity, and improves the air cooling effect, thereby enabling grinding at low temperatures.

[0028] To facilitate the centralized collection of seasoning powder, preferably, the annular screen includes a lower arc plate 9 and an upper arc filter 10. The lower arc plate 9 is sealed and fixedly connected to the inner wall of the grinding box 1, and the upper arc filter 10 is connected to the upper opening of the lower arc plate 9.

[0029] Specifically, since the lower arc plate 9 is sealed and fixedly connected to the inner wall of the grinding box 1, and the upper arc filter 10 is connected to the upper opening of the lower arc plate 9, the seasoning powder will not fall into the lower part of the grinding box 1. During the grinding process, the seasoning powder that meets the particle size will enter the upper part of the grinding box 1 from the upper arc filter 10 under the action of the wind force of the fan blade 7, which facilitates the centralized collection of the seasoning powder.

[0030] To avoid clogging of the annular screen and improve the grinding effect on plant materials, preferably, the upper arc-shaped filter screen 10 is provided with arc-shaped guide plates 11 at both ends, and the lower arc-shaped plate 9 is provided with arc-shaped guide grooves 12 at both ends. The arc-shaped guide plates 11 are slidably connected to the arc-shaped guide grooves 12 on the same side. The arc-shaped guide groove 12 on the right side is provided with a first elastic element 13, which is a spring. The inner wall of the arc-shaped guide plate 11 on the right side is provided with an elastic metal sheet 14, which is made of stainless steel.

[0031] Specifically, when the circular protrusion 5 contacts the elastic metal sheet 14 during rotation, the elastic metal sheet 14 will drive the upper arc-shaped filter screen 10 to rotate and compress the first elastic element 13. When the elastic metal sheet 14 contacts the arc-shaped guide groove 12, the elastic metal sheet 14 will be blocked by the arc-shaped guide groove 12 and will no longer rotate. The elastic metal sheet 14 will deform and bend until the circular protrusion 5 separates from the elastic metal sheet 14. Then the first elastic element 13 will release its elastic potential energy, causing the upper arc-shaped filter screen 10 to sway left and right. During the swaying process, the seasoning powder that is blocked on the upper arc-shaped filter screen 10 will be shaken off, which helps to prevent the upper arc-shaped filter screen 10 from being blocked by seasoning powder. In addition, when the plant material comes into contact with the left and right swaying upper arc-shaped filter screen 10, it will generate friction and shearing on the plant material, improving the grinding effect of the plant material.

[0032] In order to improve the grinding effect on plant materials, preferably, a second elastic element 16 is provided inside the arc-shaped guide groove 12 on the left side, and the second elastic element 16 is a spring.

[0033] Specifically, when the first elastic element 13 is compressed, the second elastic element 16 will be stretched, and when the first elastic element 13 is stretched, the second elastic element 16 will be compressed, increasing the elastic potential energy, improving the left and right swaying of the upper arc-shaped filter screen 10, improving the frictional shearing ability of the plant material, and thus improving the grinding effect of the plant material.

[0034] To achieve the purpose of collecting seasoning powder, preferably, a collection tank 17 is also included. A filter cylinder 18 is provided inside the collection tank 17. The upper and lower ends of the filter cylinder 18 are sealed to the collection tank 17. An air outlet pipe 19 for air discharge is provided on the side wall of the collection tank 17. A collection pipe 15 extending from the upper end of the collection tank 17 into the filter cylinder 18 is provided at the upper end of the grinding box 1.

[0035] Specifically, under the action of the wind force of the fan blade 7, the seasoning powder enters the filter cylinder 18 from the collection pipe 15. The filter cylinder 18 intercepts the seasoning powder and transfers it to the collection tank 17, while the air is discharged from the air outlet pipe 19.

[0036] In order to achieve the purpose of unloading the seasoning powder, preferably, the lower end of the collection tank 17 is provided with a discharge pipe 20, the outer wall of the discharge pipe 20 is provided with a second drive unit 21, and the output end of the second drive unit 21 is provided with a plurality of discharge plates 22 located inside the discharge pipe 20.

[0037] Specifically, the second drive unit 21 is activated, which drives the feeding plate 22 to rotate, ensuring even feeding and preventing seasoning powder from clogging the discharge pipe 20.

[0038] Preferably, it also includes a feeding mechanism, which includes a screw conveyor 25 that is decelerated and connected to the rotating shaft 2 and a feeding cylinder 26 that is fixedly connected to the side wall of the grinding box 1. The screw conveyor 25 is rotatably connected to the inside of the feeding cylinder 26, and a feeding hopper 27 is provided on the feeding cylinder 26.

[0039] Specifically, the rotating shaft 2 drives the screw conveyor 25 to rotate at a reduced speed through the reducer, and uniformly transports the plant raw materials in the feed hopper 27 to the grinding box 1. The grinding is carried out while feeding, resulting in high grinding efficiency. The reducer is a commonly used device by those skilled in the art, and its principle and usage are common knowledge, so it will not be described in detail here.

[0040] Compared to existing technologies, this invention utilizes a combination of a grinding chamber 1, an annular screen, a rotating shaft 2, a connecting plate 3, a crushing plate 4, a first driving unit 6, and a cooling chamber 8. The first driving unit 6 drives the connecting plate 3 to rotate via the rotating shaft 2, and the connecting plate 3 drives the crushing plate 4 to rotate. While the crushing plate 4 crushes and grinds the plant materials, it also drives the airflow within the grinding chamber 1. In addition, the cooling medium circulates within the cooling chamber 8, allowing the heat generated during the grinding process to be transferred from the crushing plate 4 to the cooling medium. This ensures that the plant materials are ground at a low temperature. After grinding, the seasoning powder that meets the particle size requirements passes through the annular screen and enters the grinding chamber 1, separating from the plant materials. This prevents the seasoning powder from developing off-flavors or unpleasant tastes after being heated, thus improving the final flavor and texture of the seasoning powder product.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
