Description

Technical Field

[0001] This invention relates to the field of food processing equipment, and in particular to a sieving device for glutinous rice cake powder. Background Technology

[0002] To make a glutinous rice cake, take a 3-pound cake as an example. Use 1 pound of eggs, 1 pound of white sugar, and 1 pound of glutinous rice flour. First, beat the eggs, add the white sugar and stir until dissolved, then add the glutinous rice flour and stir into a paste. Steam over high heat for about 45 minutes until the cake rises and turns a light yellow and soft state.

[0003] To reduce the grainy texture of glutinous rice cakes, the glutinous rice flour needs to be sieved. On August 28, 2023, our company proposed CN220658316U "Sieving Device for Water-Ground Glutinous Rice Flour", which discloses that the support plate slides into the support column through the second slide groove. At this time, the slide rail at the bottom of the sieve plate corresponds to the third slide groove above the support plate. The motor is turned on, and the motor drives the motor shaft to rotate, which in turn drives the rotating plate to rotate. The rotating plate drives the connecting plate to rotate, which in turn drives the moving block to move horizontally in the first slide groove. At this time, the sieve plate, which is fixedly connected to the connecting arm of the moving block, moves horizontally in the third slide groove. Material is poured onto the sieve plate, and the horizontal movement of the sieve plate completes the material sieving. The sieved material can be removed by sliding the support plate.

[0004] However, in actual use, although the sieve plate can move horizontally, it is still difficult to avoid the problem of glutinous rice flour getting stuck in the sieve plate mesh. The horizontal movement method has obvious limitations; it can only move the material on the surface, and it cannot remove glutinous rice flour that is tightly stuck deep in the mesh. As the usage time goes by, more and more glutinous rice flour remains in the mesh, causing large-scale blockage of the sieve plate mesh. The originally unobstructed mesh becomes congested, the material cannot pass through smoothly, the screening efficiency is greatly reduced, and the production progress is seriously affected.

[0005] To address this issue, we also tried using vibration for sieving. Vibration does loosen the glutinous rice flour stuck in the mesh to some extent. Under the vibrating sieve, the glutinous rice flour that was initially tightly blocked in the mesh slowly passes through as the sieve vibrates. Superficially, the mesh appears to be clear, and the material can pass through smoothly again. However, this method has serious drawbacks. The glutinous rice flour that vibrates through the mesh is itself the part that doesn't meet the sieving requirements and needs to be sieved. Now, it's mixed in with the material that should be acceptable, leading to inaccurate sieving results. This means we have to sieve the material again after it has already been sieved once, which not only consumes more time and effort but also increases production costs, making the entire production process more cumbersome and inefficient. Summary of the Invention

[0006] This invention provides a sieving device for glutinous rice cake powder, which solves the problem of glutinous rice powder getting stuck in holes through mechanical structural innovation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides a sieving device for glutinous rice cake flour, comprising:

[0009] A base, on which a support rod is provided;

[0010] A circular support frame is mounted on a support rod, and the inner wall of the circular support frame has a groove along the circumference.

[0011] The sieve plate body is circular and is set in the groove of the circular ring support frame, with an movable gap between it and the bottom of the groove.

The vertical rod includes a wave section and a lower vertical section. A limiting block is provided on the lower vertical section. Both the screen plate body and the collecting tray have through holes. The vertical rod passes through the through holes of the screen plate body and the collecting tray. As the wave section passes through the through holes, the screen plate body swings laterally, lifting the vertical rod. As the lower vertical section passes through the through holes, the ejector pin corresponds one-to-one with the screen hole of the screen plate body. As the vertical rod continues to be lifted, the limiting block contacts the collecting tray, pushing the collecting tray upward. The ejector pin passes through the screen hole.

[0015] Preferably, the circular support frame is composed of two semi-circular rings connected by bolts.

[0016] Preferably, the sieve plate body includes a sieve frame located on the outer ring and a sieve plate located inside the sieve frame. The sieve frame is set in the groove of the circular support frame, and there is an movable gap between the sieve frame and the bottom of the groove. The sieve holes are evenly arranged on the sieve plate.

[0017] Preferably, the bottom of the groove is provided with a sponge pad.

[0018] Preferably, the vertical rod further includes an upper vertical section, which is located at the top of the wave section.

[0019] Preferably, the upper vertical segment, the middle wavy segment, and the lower vertical segment all have the same diameter, and the transition at the joints is smooth.

[0020] Preferably, the relationship between the vertical rod and the sieve plate body and the collection tray falls into three categories:

[0021] The upper vertical section passes through the perforation of the sieve plate body, and the lower vertical section passes through the perforation of the collection tray. The limiting block does not contact the collection tray, and the collection tray is supported by the support plate.

[0022] The wavy section passes through the perforations of the sieve plate body, and the lower vertical section passes through the perforations of the collection tray. The limiting block does not contact the collection tray, and the collection tray is supported by the support plate.

[0023] The lower vertical section passes through the perforation of the sieve plate body and the perforation of the collection tray. The limiting block contacts the collection tray, and the collection tray is supported by the limiting block.

[0024] Preferably, the perforations on the sieve plate body and the collecting tray are equipped with ball bearings that contact the side wall of the vertical rod.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In this invention, a hydraulic cylinder drives a vertical rod to move up and down. The wave section passes through the perforation, and the main body of the sieve plate swings laterally to achieve the sieving work. At the same time, when the sieve holes are obviously blocked, the upper limit of the hydraulic cylinder is adjusted, and the ejector pin passes through the sieve hole to push out the glutinous rice flour blocked in the sieve hole. Through mechanical structure innovation, the problem of glutinous rice flour getting stuck in the hole is solved, and it avoids the contradiction of "cleaning the hole leading to a decrease in sieving accuracy".

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] like Figure 1 This embodiment provides a sieving device for glutinous rice cake flour, including:

[0034] A base 10, on which a support rod 11 is provided;

[0035] A circular support frame 12 is mounted on a support rod 11. The inner wall of the circular support frame 12 has a groove 13 along the circumferential direction. A sponge pad 14 is provided at the bottom of the groove 13. The circular support frame 12 is composed of two semi-circular rings connected by bolts. At the same time, the two semi-circular rings are connected to the top of the support rod 11 by bolts.

[0036] The sieve plate 16 body is circular. The sieve plate 16 body includes a sieve frame 15 located on the outer ring and a sieve plate 16 located inside the sieve frame 15. The sieve frame 15 is set in the groove 13 of the circular support frame 12, and there is an movable gap between the sieve frame 15 and the bottom of the groove 13. The sieve holes are evenly arranged on the sieve plate 16.

[0037] The presence of the sponge pad 14 serves two purposes: firstly, it fills the gap between the screen frame 15 and the bottom of the groove 13; secondly, it cushions the screen plate 16 body when it swings horizontally, preventing direct impact.

[0038] The collection tray 17 is located below the circular support frame 12 and is parallel to and vertically coaxial with the circular support frame 12. The support rod 11 is provided with a support plate 26 to support the collection tray 17. The upper surface of the collection tray 17 is provided with a plurality of pins 18.

[0039] The driving mechanism is a hydraulic cylinder 19, which is mounted on the base 10. The piston rod of the hydraulic cylinder 19 is connected to a vertical rod with its top facing upward. The vertical rod includes a wave section 20 and a lower vertical section 21. A limiting block 22 is provided on the lower vertical section 21. Both the sieve plate 16 and the collection tray 17 are provided with through holes 24. The vertical rod passes through the through holes 24 of the sieve plate 16 and the collection tray 17. The wave section 20 passes through the through holes 24, causing the sieve plate 16 to swing laterally and lift the vertical rod. The lower vertical section 21 passes through the through holes 24, and the ejector pin 18 corresponds one-to-one with the sieve holes of the sieve plate 16. The vertical rod continues to lift, and the limiting block 22 contacts the collection tray 17, pushing the collection tray 17 to rise. The ejector pin 18 passes through the sieve holes.

[0040] Place the base 10 on the ground. During installation, first pass the vertical rod connected to the piston rod of the hydraulic cylinder 19 through the through hole 24 of the collecting tray 17, place the collecting tray 17 on the support plate on the support rod 11, and then place the sieve plate 16 inside the sieve frame 15. It should be noted that the sieve frame 15 in this embodiment is an integral circular ring structure with a stepped surface on the inner side. The sieve plate 16 is placed on the stepped surface and then fixed with screws. At the same time, in order to prevent the glutinous rice flour on the sieve plate 16 from falling out of the frame, a protective plate 25 is provided on the sieve plate 16. After the sieve plate 16 is installed, the main body of the sieve plate 16 is wrapped by two semi-circular rings. The wrapped circular ring support frame 12 is fixed on the support rod 11, and the vertical rod passes through the through hole 24 of the main body of the sieve plate 16.

[0041] The vertical rod also includes an upper vertical section 23, which is located at the top of the wave section 20. Compared to the perforations 24 through which the wave section 20 penetrates the main body of the sieve plate 16 and the collection tray 17, the vertical section is easier to insert. The upper vertical section 23, the middle wave section 20, and the lower vertical section 21 all have the same diameter, and the transition at the joints is smooth. This smooth transition ensures that the vertical rod moves smoothly up and down within the perforations 24.

[0042] To reduce friction between the vertical rod and the perforations 24 of the sieve plate 16 and the collection tray 17, ball bearings are provided in the perforations 24 of the sieve plate 16 and the collection tray 17 to contact the side wall of the vertical rod.

[0043] The relationship between the vertical rod and the main body of the sieve plate 16 and the collection tray 17 can be divided into three cases:

[0044] like Figure 1 The upper vertical section 23 passes through the perforation 24 of the main body of the sieve plate 16, and the lower vertical section 21 passes through the perforation 24 of the collection tray 17. The limiting block 22 does not contact the collection tray 17, and the collection tray 17 is supported by the support plate. At this time, the sieve holes on the sieve plate 16 correspond one-to-one with the pins 18 on the collection tray 17, and there is a gap. The sieve plate 16 and the collection tray 17 do not move.

[0045] like Figure 2 The wave segment 20 passes through the perforation 24 of the main body of the sieve plate 16, and the lower vertical segment 21 passes through the perforation 24 of the collection tray 17. The limiting block 22 does not contact the collection tray 17, and the collection tray 17 is supported by the support plate. At this time, there is still a gap between the sieve holes on the sieve plate 16 and the pins 18 on the collection tray 17. As the wave segment 20 passes through the perforation 24, the main body of the sieve plate 16 swings laterally to sieve the glutinous rice flour on the sieve plate 16, while the collection tray 17 remains stationary.

[0046] like Figure 3 The lower vertical section 21 passes through the perforation 24 of the main body of the sieve plate 16 and the perforation 24 of the collecting plate 17. The limiting block 22 contacts the collecting plate 17, and the collecting plate 17 is supported by the limiting block 22. At this time, the sieve plate 16 and the collecting plate 17 are stationary, and the piston rod continues to rise. Driven by the limiting block 22, the distance between the sieve holes on the sieve plate 16 and the ejector pins 18 on the collecting plate 17 decreases until the ejector pins 18 pass through the sieve holes.

[0047] It should be noted that the stroke of the piston rod of hydraulic cylinder 19 meets the requirements of the above three situations.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0049] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
