Description

Technical Field

[0001] This invention is applied to the field of health product manufacturing, and relates to the production of wheat selenium peptide nutritional products. Specifically, it is a centrifuge for rapidly drying the buds separated from malt. Background Technology

[0002] Selenium-enriched wheat peptides, a selenium-containing nutritional supplement, are manufactured using black wheat as the raw material. Black wheat is cultured in a selenium-containing nutrient solution to produce high-selenium malt. The malt sprouts and roots are then separated. The malt sprouts with higher water content are pulverized into nano-sized fine powder using an angle grinder, and then dried and sterilized to produce the selenium-enriched wheat peptide nutritional supplement. It is difficult to pulverize dried malt sprouts into nano-sized particles; therefore, separation of the malt sprouts and roots can only be achieved while the sprouts are still moist. Under moist conditions, the cells of the malt sprouts swell after absorbing water, filling the gaps and significantly increasing their density to 1.1–1.3 g / cm³. The roots have a finer, relatively denser structure, and their density increase after absorbing water is less than that of the malt sprouts, with a moist density of 0.8–1.0 g / cm³. Mechanical kneading is recommended to enhance the separation effect between the two. Based on the aforementioned physical characteristics, the applicant has applied for a patent for equipment related to the separation of malt buds and roots. This equipment utilizes the difference in specific gravity between water and the two components to separate them. Roots float and are discharged with the flowing water, while buds sink to the bottom of the equipment. The equipment releases buds by intermittently opening the door, with the water flow carrying them out. This invention is applied after a malt separation device to collect the buds in the water and centrifuge them to dry them.

[0003] Solid-liquid separation often employs centrifugal drying, a common drying method in daily life. Examples include CN219160839U, a rapid dehydration device for veterinary medicinal materials; CN115096051A, a centrifugal drying device; and CN217615359U, a centrifuge for pharmaceutical production. Compared to these technical solutions, this utility model has a simpler structure and lower manufacturing cost. Other examples include CN222267470U, a walnut oil centrifugal separation device; and CN210393815U, a swill oil-water separation tank. While these have simple structures, they are not suitable for continuous production. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a bud centrifugal dryer that uses centrifugal rotation to dry buds. It is simple to operate, suitable for continuous operation, and has low manufacturing cost.

[0005] The technical solution adopted in this utility model is as follows: The bud centrifuge includes a fixed component, a vertical moving component, and a rotating component. The fixed component includes a worktable, a central platform, a cylindrical platform, and a bottom plate. The bottom plate and the side plates of the worktable form a square or circular bucket for collecting water centrifuged from the centrifugation process. A water outlet is located at the lowest point of the bottom plate, connected to a return water pipe for water recycling. The central platform is located at the center of the bottom plate, and the cylindrical platform is located between the central platform and the side plates of the worktable, with the two cylindrical platforms arranged symmetrically. The vertical moving component includes a water-blocking ring, a top ring plate, a positioning plate, and a top cylindrical plate. The ear plate of the water-blocking ring is fixedly connected to the top ring plate to prevent the water-blocking ring from tilting during vertical movement. The top ring plate is fixed to the top of the cylinder rod of a lifting ring cylinder, which drives the vertical movement of the water-blocking ring. Two lifting ring cylinders are respectively installed on both sides of the worktable. Both the positioning plate and the top cylinder plate are fixedly connected to the cylinder rod of the lifting cylinder. The lifting cylinder is installed inside the cylindrical platform, with the upper plate of the platform located between the positioning plate and the top cylinder plate, forming a mating structure. When the lifting cylinder rises, the upper plate limits the positioning plate; when it descends, the upper plate limits the top cylinder plate. The rotating mechanism includes a turntable supported by a central platform, which is rotatably connected. A belt drive is connected to the lower end of the turntable's shaft, and the turntable is driven to rotate by the belt drive. A rotating block is fixed at the center of the upper surface of the turntable, and this rotating block mates with the central groove of the bottom plate of the centrifuge cylinder, enabling the turntable to drive the centrifuge cylinder to rotate centrifugally.

[0006] In another embodiment, the top ring plate and lifting cylinder of the water-blocking ring are replaced by a counterweight mechanism, which includes a counterweight, a support, and a fixed pulley. The support is installed on both sides of the workbench, and the fixed pulley is fixed on the top plate of the support. The groove of the fixed pulley is fitted with a steel wire rope, and the two ends of the steel wire rope are respectively fixedly connected to the counterweight and the ear plate. A guide rod is fixed on the ear plate, and the guide rod engages with a guide hole on the top plate to ensure stable up-and-down movement of the water-blocking ring.

[0007] Furthermore, a water-retaining ring is fitted onto the outside of the centrifuge cylinder to collect the water ejected during centrifugation. Water-permeable holes are provided on the bottom and side plates of the centrifuge cylinder.

[0008] Furthermore, the plane of the water-retaining ring that contacts the workbench is lower than the surface of the workbench to prevent splashed water from leaking out of the workbench surface.

[0009] Furthermore, a flange is provided around the top cylinder plate and the turntable, which serves two purposes: firstly, to reinforce the flat plate, and secondly, to prevent water from leaking through the gaps in the components.

[0010] Furthermore, the rotating block is prism-shaped, or frustum-shaped, or a combination of an upper frustum-shaped block and a lower prism with the same edge. Correspondingly, the central groove of the centrifuge cylinder bottom plate is machined into a shape that matches it.

[0011] The beneficial effects of this invention are: together with a centrifuge, it enables continuous operation of bud drying. This invention is simple to operate and convenient to use; the rotating parts are enclosed within a water-retaining ring, ensuring good safety. Attached Figure Description

Detailed Implementation

[0013] The terms "upper and lower" and "top and bottom" below refer to the relative upper and lower positions of this utility model in its installation and working state, i.e., the attached... Figure 1 The relative positions of the components are shown. To facilitate the display of the main structure of this utility model, reinforcing structures that do not affect function, such as reinforcing ribs and reinforcing plates, are not shown. Some structures, such as cylinders and belt drive components, are existing technologies. Automatic control is existing technology and is not described in detail. Example 1

[0014] The structure of the spin dryer in this embodiment is shown in the attached figure. Figure 1-3 As shown, the operation mainly includes two actions: up and down movement and centrifugal rotation. To better understand the structure of the spin dryer, the fixed parts in the attached figure are distinguished by 45° cross-sectional lines, the up and down moving parts by horizontal cross-sectional lines, and the rotating parts by 135° cross-sectional lines.

[0015] The fixed components of the spin dryer include a worktable 4, a center platform 6, a cylindrical platform 9, and a drum bottom plate 14. The moving components include a water-blocking ring 1, a positioning plate 10, a top cylinder plate 11, and a top ring plate 12. The components that drive the moving components are cylinders, including a lifting ring cylinder 2 and a lifting cylinder cylinder 5. The rotating components include a turntable 8, and the components that drive the rotation are belt drive components 7.

[0016] The side plate of the workbench 4 and the bottom plate of the bucket 14 constitute a water bucket. The water bucket can be a square bucket or a round bucket. To facilitate the drainage of water, the bottom plate of the bucket 14 is inclined. An outlet 15 is set at the lowest point of the bottom plate of the bucket 14. In this way, the water in the bucket can flow from the outlet 15 into the connected return pipe or the ground ditch for recycling.

[0017] A central platform 6 is set at the center of the bottom plate 14 of the centrifuge drum. The platform 6 supports a turntable 8, and the two are rotatably connected. The drive shaft of the turntable 8 extends downward from the platform of the central platform and is connected to a belt drive component 7. The belt drive component is connected to a motor. After the motor is started, it can drive the turntable 8 to rotate through the belt drive component 7. A rotating block 13 is fixed at the center of the upper surface of the turntable 8. In this embodiment, the rotating block 13 is a square block. The square block cooperates with the central square groove of the bottom plate of the centrifuge drum 3 to drive the centrifuge drum 3 to rotate.

[0018] Two cylindrical platforms 9 are symmetrically positioned between the side plates of the central platform 6 and the worktable 4. A lifting cylinder 5 is installed inside each cylindrical platform 9. The cylinder rod of the lifting cylinder 5 passes through the upper plate of the cylindrical platform 9 and is fixedly connected to the top plate 11 and the positioning plate 10. The top plate 11 and the positioning plate 10 are located above and below the upper plate, respectively, and cooperate with the upper plate. When the lifting cylinder 5 lifts the centrifuge cylinder 3 upwards, the upper surface of the positioning plate 10 contacts the lower surface of the upper plate, and the upper surface of the top plate 11 is flush with the surface of the worktable 4, facilitating the translation of the centrifuge cylinder on the worktable surface. When the cylinder rod of the lifting cylinder 5 moves downwards, and the lower surface of the top plate 11 contacts the upper surface of the upper plate, the top plate 11 detaches from the bottom plate of the centrifuge cylinder, and the centrifuge cylinder is completely supported by the turntable. The central square groove of the centrifuge cylinder cooperates with the square block to achieve safe rotation of the centrifuge cylinder.

[0019] On the workbench, on both sides of the centrifuge cylinder's direction of movement, there are lifting ring cylinders 2. A top ring plate 12 is fixed to the top of the cylinder rod of the lifting ring cylinder 2, and the top ring plate 12 engages with the ear plate of the water-retaining ring 1. When the cylinder rod of the lifting ring cylinder 2 rises, the top ring plate 12 lifts the ear plate, thereby causing the water-retaining ring 1 to rise. When the cylinder rod of the lifting ring cylinder 2 descends, the water-retaining ring 1 descends due to its own weight and rests on the workbench surface. To prevent the water-retaining ring from tipping over during the up-and-down movement of the cylinder rod of the lifting ring cylinder 2, the ear plate should be fixedly connected to the top ring plate 12. The water-retaining ring 1 is fitted onto the outside of the centrifuge cylinder to collect the water ejected during centrifugal rotation and deposit it into a water bucket. To prevent water from flowing out of the workbench surface from the lower end of the water-retaining ring, the plane of the water-retaining ring in contact with the workbench surface should be lower than the workbench surface.

[0020] When using this embodiment, as shown in the attached document... Figure 1As shown, lifting cylinder 2 raises the water-retaining ring 1, and lifting cylinder 5 raises the top cylinder plate 11. The centrifuge cylinder 3 moves horizontally from below the water-retaining ring to above the turntable 8. Lifting cylinder 5 descends, causing the central square groove of the centrifuge cylinder's bottom plate to align with the central square block of the turntable 8, thus completely supporting the centrifuge cylinder on the turntable. Subsequently, lifting cylinder 2 descends, and the water-retaining ring 1 is placed on the workbench surface, as shown in the attached diagram. Figure 3 As shown. Water and malt stalks from the bottom of the malt separation device are fed into a centrifuge cylinder. Centrifuge cylinder 3 is a conveyor for holding the malt stalks, and its bottom and side plates are equipped with water permeable holes. A large amount of water falls into a water tank through these holes. Then, the belt drive component 7 is activated, and the centrifuge cylinder rotates under the drive of the turntable 8. Under the action of centrifugal force, all the free water on the malt stalks is thrown out. After the malt stalks are dried, the lifting ring cylinder 2 and the lifting cylinder cylinder 5 rise, removing the centrifuge cylinder. The next centrifuge cylinder moves horizontally onto the turntable for the next centrifugal drying operation. The dried malt stalks are sent to the next process for washing and pulverizing.

[0021] In this embodiment, the cylinder can be replaced by a hydraulic cylinder, but since the purchase cost of the cylinder is low, it should be given priority. Example 2

[0022] In this embodiment, the lifting ring cylinder 2 is replaced by a counterweight mechanism, the structure of which is shown in the attached figure. Figure 4 As shown. The counterweight mechanism includes a counterweight 16, a support 17, and a fixed pulley 19. On the workbench 4, on both sides of the centrifuge cylinder 3 in the direction of movement, the support 17 is fixed. On the top plate 20 of the support, the fixed pulley 19 is fixed. A steel wire rope fits into the groove of the fixed pulley 19. The two ends of the steel wire rope are fixed to the counterweight 16 and the ear plate, respectively. A guide rod 18 is fixed to the ear plate, passing through the guide hole of the top plate 20. The cooperation of the guide rod and the guide hole constrains the water-blocking ring, making its up-and-down movement smooth. When the water-blocking ring 1 needs to be moved upwards, the counterweight 16 is pulled down, and the steel wire rope drives the water-blocking ring upwards under the guidance. When it needs to be lowered, the counterweight 16 is moved upwards, and the water-blocking ring, under the action of gravity, drives the steel wire rope downwards together.

[0023] To prevent splashed water from leaking through the gap between the central platform 6 and the cylindrical platform 9, downward-curved edges are provided around the top plate 11 and the turntable 8. These downward-curved edges prevent splashed water from entering the surface of the central platform 6 or the upper plate of the cylindrical platform 9, and guide the water droplets into the water bucket. In addition, the downward-curved edges also help to strengthen the flat plate and prevent it from deforming.

[0024] Compared to Example 1, this embodiment uses two fewer cylinders, resulting in lower manufacturing costs, but it requires manual operation to move the baffle plate up and down. Example 3

[0025] To facilitate the cooperation between the rotating block 13 and the centrifuge tube 3, the upper part of the square block in Embodiment 1 can be set as a frustum of a square pyramid, and the lower part as a prism, as shown in the attached figure. Figure 5As shown, the shape of the central groove of the centrifuge tube bottom plate corresponds to that of the rotating block 13. The lower part is a quadrangular prism groove, and the upper part is a quadrangular pyramidal truncated groove. The inclined plane guiding function of the quadrangular pyramidal truncated groove is used to realize the rapid positioning and assembly of the quadrangular prism and the quadrangular prism groove.

[0026] The rotating block 13 can be a prism-shaped structure, such as a triangular prism or a hexagonal prism; it can also be a combination of an upper frustum and a lower prism, such as an upper triangular frustum and a lower triangular prism, or an upper hexagonal frustum and a lower hexagonal prism; or it can be a single frustum, such as a triangular frustum or a hexagonal frustum. Correspondingly, the central groove of the centrifuge cylinder bottom plate is machined into a multi-faceted shape that matches the rotating block. The rotational torque is transmitted using the frustum edges, and the inclined plane guiding function of the frustum enables rapid assembly, which also helps to improve the assembly accuracy between the rotating block and the central groove.

[0027] If the lifting ring cylinder 2 and the lifting cylinder 5, or the drive mechanism of the fixed pulley 19 and the lifting cylinder 5, are connected to the automatic control system, the operator only needs to move the centrifuge cylinder up and down to complete the assembly of the rotating block and the centrifuge cylinder, thus achieving semi-automatic operation of bud spin-drying. If the centrifuge cylinder can achieve positioning and automatic feeding, then bud spin-drying can be automated.

[0028] This invention, together with the centrifuge drum, synchronizes with the intermittent discharge rhythm of malt from the malt separation device, enabling continuous malt drying. This invention is simple to operate and convenient, involving only centrifugal drying and vertical movement, resulting in low manufacturing costs. All rotating parts are enclosed within a water-retaining ring, ensuring good safety.
