Description

Technical Field

[0001] This invention relates to rice noodle processing equipment, specifically a rice noodle aging device. Background Technology

[0002] Rice noodles are a popular food enjoyed by residents of many southern provinces in my country and some Southeast Asian countries. The processing techniques for rice noodles vary depending on the region and desired texture, but the basic steps include: soaking, grinding, extruding, aging, steaming, secondary aging, loosening, drying, cutting, and packaging the rice.

[0003] The "aging" process in rice noodle production lines serves several purposes: it allows the gelatinized starch in the rice noodles to fully age, resulting in chewy noodles that don't become mushy in the soup, and it also reduces the stickiness between the rice noodles, meaning that the disordered starch molecules are partially rearranged into an ordered order.

[0004] Traditional aging devices rely primarily on manual powder handling and lack steam, depending on natural aging. This results in insufficient output, low utilization efficiency, low automation, and uneven and incomplete aging. Furthermore, low ambient temperatures severely impact aging quality, leading to problems with output, efficiency, and aging quality.

[0005] A search revealed that patent publication number "CN112189783A" discloses a multi-stage conveying device for rice noodle aging, including a box, a motor, a conveyor chain, and a fan. The conveyor chain is a paired chain structure, driven by the motor through the chain. Several pairs of conveyor chains are installed inside the box. The inner wall of the box is provided with horizontally arranged ventilation holes. The box is also connected to an external air conditioning system to facilitate precise control of the rice noodle aging process. The fan is located at the top and bottom of the box.

[0006] This technical solution can automatically transport rice noodle sticks containing rice noodles into the aging room, improving efficiency and reducing manual labor intensity. However, this technical solution has the following problems:

[0007] 1. Because this technical solution uses a multi-layer conveyor chain, it is inconvenient for workers to place the rice noodle sticks on the upper layers of the conveyor chain.

[0008] 2. When rice noodle sticks are placed on the conveyor chain manually, uneven placement may occur due to varying placement times. Summary of the Invention

[0009] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a rice noodle aging device. The rice noodle aging device can automatically move the rice noodles to each layer of conveyor belt through a lifting mechanism and a material transfer mechanism, so that they can enter the substrate and be aged after hot steam is introduced, thereby reducing labor costs and improving processing efficiency. At the same time, a heat circulation mechanism is set inside the substrate to maintain a consistent aging temperature inside, thereby ensuring that the aging quality of rice noodles on each layer of conveyor belt is consistent.

[0010] This invention is implemented by constructing a rice noodle aging device, comprising a substrate, a conveying mechanism, a lifting mechanism, a material transfer mechanism, and a thermal circulation mechanism. The substrate has a channel for material to enter and exit in a straight line and for hot steam to be introduced into the channel. The conveying mechanism is disposed on both sides inside the channel of the substrate. The lifting mechanism is disposed at the open end of the substrate. The material transfer mechanism is used to transfer the material in the lifting mechanism to the conveying mechanism. The thermal circulation mechanism is disposed in the middle position inside the substrate.

[0011] Furthermore, plates are provided on both sides of the inner end of the channel of the substrate. A conveying mechanism is connected to the plates through two parallel rotating shafts. The conveying mechanism consists of a sprocket and a chain. The purpose of this arrangement is to facilitate the lifting and conveying of both ends of the rice noodle rod, and to prevent the rice noodles on the rice noodle rod from coming into contact with the conveying mechanism and getting dirty.

[0012] Furthermore, the lifting mechanism includes a spiral shaft, a lifting block, a guide rail, and a support block A; the spiral shaft is vertically arranged on the outer side of the plate and keeps rotating; the lifting block is threadedly connected to the spiral shaft; the guide rail is arranged on the plate and contacts the lifting block to facilitate the lifting of the lifting block; the support block A is arranged on the outer end of the lifting block, the purpose of which is to facilitate lifting the rice noodle rod to the high-end conveying mechanism position, so as to facilitate layered placement of rice noodles.

[0013] Furthermore, the material transfer mechanism includes a mounting block, a sliding plate A, a mounting plate, a support block B, a cylinder B, and a connecting plate; the mounting block is disposed on the outer side of the plate at the lower end of the conveying mechanism, and the cylinder A is disposed inside the mounting block;

[0014] The sliding plate A is located at the outer end of the mounting block and is slidably connected to the mounting block via cylinder A; the mounting plate is located at the outer end of the sliding plate; the support block B is movably connected to the top of the mounting plate via a guide post; the cylinder B is located on the side wall of the mounting plate and its extension / retraction direction is vertical; the connecting plate is located on the extension / retraction part of the cylinder B and is connected to the support block B. The purpose of this arrangement is to move the rice noodle rod on the lifting mechanism to each layer of the conveying mechanism, achieving uniform layering of the rice noodles and ensuring the quality of aging.

[0015] Furthermore, the cylinder A extends and retracts between the conveying mechanism and the lifting mechanism. The purpose of this arrangement is to move the rice noodle rod on the lifting mechanism to each layer of the conveying mechanism.

[0016] Furthermore, both the top of the support block A and the support block B are provided with grooves for supporting the powder-holding rod. The purpose of this design is to facilitate the placement and fixing of the powder-holding rod.

[0017] Preferably, the conveying mechanism and the material transfer mechanism consist of four layers, which are evenly distributed vertically within the channel of the substrate.

[0018] Furthermore, the heat circulation mechanism includes two frames, a crossbeam, and a fan; the two frames are arranged opposite each other on both sides of the channel in the base; the crossbeam is connected between the top ends of the two frames; and the fan is mounted on the crossbeam.

[0019] Furthermore, the frame is hollow inside and interconnected, and multiple air vents are evenly opened on the lower end of the opposite side of the frame. One end of the crossbeam is connected to the air outlet of the fan, and the other end of the crossbeam is connected to the interior of the two frames.

[0020] Furthermore, the diameter of the air outlet further away from the fan end is larger than that of the air outlet closer to the fan end; preferably, the diameter of the air outlet gradually increases from the end further away from the fan. The purpose of this setting is to ensure that the air volume of the air outlets at both ends is the same as that of the middle air outlet as much as possible, because the air pressure is lower as it moves away from the fan. The defect of low air pressure is compensated by increasing the diameter of the outlet, thereby ensuring that the air volume of each air outlet is the same as much as possible; and the air outlet also facilitates the circulation of heat.

[0021] Furthermore, the base is made of 304 stainless steel frame, with the upper side of the opening end of the base kept closed and an automatic lifting sealing door installed on the lower side of the opening end. The purpose of this setting is to reduce the leakage of hot steam during aging and to facilitate the handling of rice noodles.

[0022] The present invention has the following beneficial effects:

[0023] This invention facilitates the automatic conveying of rice noodles through a conveying and transferring mechanism located inside the substrate, thereby achieving automated aging and ensuring processing efficiency. Furthermore, the multi-layer conveying and lifting mechanism ensures that more rice noodles can be accommodated for aging operations each time. At the same time, the internal heat circulation mechanism ensures that the internal temperature tends to be uniform, thus guaranteeing the overall aging quality of the rice noodles.

[0024] In this invention, the shape of the support block is designed to facilitate the placement and fixing of the powder support rod, thereby facilitating its automatic transport to the conveying mechanism for aging.

[0025] By setting vents of different sizes at the bottom of the frame, the flow rate of hot steam discharged from all parts of the bottom is kept consistent, thereby ensuring the quality of aging. Attached Figure Description

[0033] The following will be combined with the appendix Figures 1-7 This invention will be described in detail, and the technical solutions in the embodiments of this invention will be clearly and completely described.

[0035] In this embodiment, plates 2 are provided on both sides of the inner end of the channel of the base 1. The plates 2 are connected to a conveying mechanism 7 by two parallel rotating shafts. The conveying mechanism 7 consists of a sprocket and a chain.

[0037] like Figure 6 As shown, in this embodiment, the material transfer mechanism includes a mounting block 15, a sliding plate A16, a mounting plate 8, a support block B9, a cylinder B17, and a connecting plate 18; the mounting block 15 is disposed on the outer side of the plate 2 at the lower end of the conveying mechanism 7, and a cylinder A14 is disposed inside the mounting block 15.

[0038] The sliding plate A16 is disposed at the outer end of the mounting block 15 and is slidably connected to the mounting block 15 via the cylinder A14; the mounting plate 8 is disposed at the outer end of the sliding plate 16; the support block B9 is movably connected to the top of the mounting plate 8 via the guide post; the cylinder B17 is disposed on the side wall of the mounting plate 8 and is extended in the vertical direction; the connecting plate 18 is disposed on the extension part of the cylinder B17 and is connected to the support block B9.

[0039] In this embodiment, the cylinder A14 extends and retracts back and forth between the conveying mechanism 7 and the lifting mechanism.

[0040] like Figure 4 and Figure 5 As shown, in this embodiment, the top ends of both the support block A6 and the support block B9 are provided with grooves for supporting the powder support rod 19.

[0041] In this embodiment, the conveying mechanism 7 and the material transfer mechanism are arranged in four layers, evenly distributed vertically within the channel of the base 1.

[0042] In this embodiment, the heat circulation mechanism includes two frames 12, a crossbeam 10, and a fan 11; the two frames 12 are arranged opposite each other on both sides of the channel in the base 1; the crossbeam 10 is connected between the top ends of the two frames 12; and the fan 11 is mounted on the crossbeam 10.

[0043] In this embodiment, the frame 12 is hollow inside and interconnected. Multiple air outlets 13 are evenly opened on the lower end of the opposite side of the frame 12. One end of the crossbeam 10 is connected to the air outlet of the fan 11, and the other end of the crossbeam 10 is connected to the interior of the two frames 12.

[0044] In this embodiment, the diameter of the air outlet 13 at the end away from the fan 11 is larger than the diameter of the air outlet at the end closer to the fan 11.

[0045] In this embodiment, the substrate is made of 304 stainless steel frame, the upper side of the opening end of the substrate is kept closed, and an automatic lifting sealing door is installed on the lower side of the opening end.

[0046] The frame is entirely made of 304 stainless steel, 15 meters long, with each rice noodle support rod spaced 31.75mm apart, and a single-row, four-layer chain conveyor.

Then, through an external conveying mechanism (such as a robotic arm or AGV trolley), the rice noodle support rod 19 is placed in the groove of the support block A6. Simultaneously, the corresponding height cylinder A14 extends, moving the support block B9 to the corresponding position on the support block A6. Next, cylinder B17 extends to lift the support block B9, causing the rice noodle support rod 19 to extend and lift the support block B9. 9. The cylinder A14 is raised and then retracted, while the flagpole B17 retracts, placing the rice noodle support rod 19 on the chain of the conveying mechanism 7. During this process, the external transmission device of the conveying mechanism of that layer is activated at regular intervals to keep the rice noodle support rod 19 evenly placed on the conveying mechanism 7 of that layer. The external drive motor repeatedly rotates the spiral shaft 3, and the lifting mechanism evenly places the rice noodle support rod on each layer of the conveying mechanism 7. Finally, the lifting and sealing door is closed, hot steam is introduced into the interior, and the fan 11 is activated at regular intervals to maintain internal heat circulation and achieve automated aging of rice noodles.
