Description

Technical Field

[0001] This invention relates to the field of rice noodle production technology, specifically to a chain conveyor type rice noodle steamer. Background Technology

[0002] In the production of rice noodle instant noodles, the raw rice noodles undergo pre-gelatinization, which involves pre-steaming and heating the raw rice noodles to fully "cook" the rice starch. This gives the rice noodles a chewy yet smooth texture after being soaked in hot water. After pre-gelatinization, the starch structure of the rice noodles is opened up, becoming porous. When consumers pour boiling water into the noodles, the water quickly re-enters, restoring them to a near-freshly cooked state within minutes.

[0003] In existing technologies, the pregelatinization of raw rice flour is carried out by static heating, which involves manually placing a batch of raw rice flour into a steamer, heating it for a period of time, and then manually removing and cooling it. This method is labor-intensive, inefficient, and difficult to adapt to the pace of modern production. Summary of the Invention

[0004] The purpose of this invention is to provide a chain conveyor type rice flour steamer, which can improve the automation level of the pre-gelatinization process of raw rice flour, thereby improving the efficiency of the pre-gelatinization process of raw rice flour.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A chain-driven rice flour steamer includes multiple cabinet units connected end-to-end. Each cabinet unit includes a frame with an outer shell. Two uprights are located on each side of the frame, and several crossbeams are positioned between the two uprights on the same side. A chain support plate is located on the inner side of each crossbeam. Multiple cabinet units share several sets of conveyor chains, with two chains in each set. The two conveyor chains in the same set are distributed laterally. The front cabinet unit has several driving sprockets, and the rear cabinet unit has several driven sprockets. The two ends of the conveyor chains are wound around the driving and driven sprockets. The feeding section of the conveyor chain and... The return section slides against the top side of the support plate. Several sprocket seats are provided on the inner side of the column. Each end of the support plate has a corresponding sprocket seat. The sprocket seat is equipped with a limiting sprocket. The limiting sprocket meshes with the lower side of the feeding section and the return section. Multiple connecting plates are provided at intervals on the conveyor chain. The connecting plates of two conveyor chains in the same group are aligned laterally. Two connecting plates aligned laterally are rotatably provided with connecting rods. Multiple receiving bowls are fixed to the connecting rods. Multiple ventilation holes are provided on the bottom wall of the receiving bowls. A counterweight is provided at the bottom of the receiving bowls. A steam tank is provided at the bottom of the frame. A cover plate is provided at the opening of the steam tank. The cover plate is provided with an air outlet.

[0006] Specifically, multiple cabinet units share two sets of conveyor chains, four crossbeams are provided between two columns on the same side, and four sprocket seats are provided on the inner side of the columns.

[0007] Specifically, the connecting piece has an L-shaped cross-section, forming a horizontal section and a vertical section. The vertical section is equipped with a rolling bearing, which supports the end of the connecting rod.

[0008] Specifically, the connecting rod is fixed with at least ten receiving cups, and the weight of a single counterweight is greater than the weight of a single receiving cup.

[0009] Specifically, the sidewalls of the steam tank are connected to several air inlet pipes.

[0010] Specifically, the vents on the cover plate include elongated holes and round holes, with the elongated holes and round holes alternating.

[0011] Specifically, the bottom wall of the receiving bowl is provided with several air vents, and each air vent is arranged circumferentially.

[0012] Specifically, a transverse guide plate is fixed between the bases of the two transverse drive sprockets. The cross-section of the transverse guide plate is arc-shaped. The center of the arc-shaped profile of the transverse eccentric guide plate is located diagonally above the center of the drive sprocket. The bottom of the counterweight is provided with a contact spherical surface, which is used to slide in contact with the transverse guide plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The chain conveyor rice flour steamer of this invention enables large-scale heating and gelatinization of raw rice flour, improving production efficiency. The rationally designed two-layer feeding section fully utilizes steam vertically, maximizing energy utilization and achieving green energy saving.

[0014] The counterweight ensures that the receiving bowl faces upwards during horizontal conveying, preventing rice noodles from spilling and facilitating feeding.

[0015] The horizontal guide plate design allows for rapid material discharge when the receiving bowl turns forward, eliminating the need for additional discharge mechanisms and making the production process more continuous and efficient.

[0016] The limiting sprocket meshes with the lower side of the feeding section and the return section to prevent the feeding section and the return section from detaching from the support plate. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] See Figures 1 to 4 A chain conveyor type rice noodle steamer includes multiple cabinet units (see point A in the figure), which are connected end to end. Each cabinet unit includes a frame, which is covered by a shell. Two uprights 11 are provided on both sides of the frame. Several crossbeams 12 are provided between the two uprights 11 on the same side. The inner side of the crossbeams 12 is provided with a chain support plate 13.

[0022] Multiple cabinet units share several sets of conveyor chains 2, with two conveyor chains 2 in each set, and the two conveyor chains 2 in the same set are distributed laterally. The front cabinet unit is equipped with several drive sprockets 21 (see...). Figure 2 , Figure 3The rear cabinet unit is equipped with several driven sprockets 22. The two ends of the conveyor chain 2 are wound around the driving sprocket 21 and the driven sprocket 22. The feeding section 23 and the return section 24 of the conveyor chain 2 are slidably attached to the top side of the support plate 13.

[0023] See Figure 4 , Figure 5 The inner side of the column 11 is provided with several sprocket seats 3, and each end of the chain support plate 13 is respectively provided with a sprocket seat 3. The sprocket seat 3 is provided with a limiting sprocket 31, which meshes with the lower side of the feeding section 23 and the return section 24. The conveyor chain 2 is provided with multiple connecting pieces 25 at intervals, and the connecting pieces 25 of the two conveyor chains 2 in the same group are aligned laterally. Two connecting pieces 25 aligned laterally are rotatably provided with connecting rods 41, and multiple receiving bowls 42 are fixedly connected to the connecting rods 41. The bottom wall of the receiving bowls 42 is provided with multiple vent holes. The bottom of the receiving bowls 42 is provided with a counterweight block 43. The bottom of the frame is provided with a steam tank 51, and the opening of the steam tank 51 is provided with a cover plate 52, and the cover plate 52 is provided with an air outlet.

[0024] Specifically, see Figures 2 to 4 Multiple cabinet units are equipped with two sets of conveyor chains 2, and four crossbeams 12 are provided between two columns 11 on the same side. Four sprocket seats 3 are provided on the inner side of the columns 11.

[0025] Specifically, see Figure 5 The connecting piece 25 has an L-shaped cross section, thus forming a horizontal piece and a vertical piece. The vertical piece is equipped with a rolling bearing, which supports the end of the connecting rod 41.

[0026] Specifically, see Figure 6 The connecting rod 41 is fixed with ten receiving cups 42, and the weight of a single counterweight 43 is greater than the weight of a single receiving cup 42.

[0027] Specifically, the sidewall of the steam tank 51 is connected to several air inlet pipes 53.

[0028] Specifically, the air vents provided on the cover plate 52 include elongated holes and round holes, with the elongated holes and round holes being alternately arranged.

[0029] Specifically, the bottom wall of the receiving bowl 42 is provided with several air vents, and each air vent is arranged circumferentially.

[0030] Specifically, the base at the mounting location of the two transverse drive sprockets 21 ( Figure 2 , Figure 3 A transverse guide plate 14 is fixedly connected between (not shown) and (the cross-section of the transverse guide plate 14 is arc-shaped), and the center of the arc-shaped contour of the transverse eccentric guide plate ( Figure 8 , Figure 9 (O1) is located at the center of the drive sprocket 21 ( Figure 8 , Figure 9The counterweight 43 is located diagonally above O2. The bottom of the counterweight 43 is provided with a contact spherical surface, which is used to slide in contact with the transverse guide plate 14.

[0031] The working principle of this invention is as follows: The raw rice flour to be pregelatinized is fed to the rear end of the chain conveyor rice flour steamer, that is, placed into the receiving bowl 42 connected to the feeding section 23 of each of the two sets of conveyor chains 2.

[0032] As the receiving bowl 42 moves forward with the feeding section 23, high-temperature steam is input into the steam tank 51 through the air inlet pipe 53 (in conjunction with...). Figure 4 , Figure 7 The steam then overflows through the vents in the cover plate 52. The bottom wall of the receiving bowl 42 has multiple vents, which helps the steam to heat and gelatinize the raw rice flour inside the receiving bowl 42.

[0033] When the receiving bowl 42 moves to the front of the chain conveyor rice noodle steamer, see Figure 8 The contact spherical surface at the bottom of the counterweight 43 will contact the rear edge of the top wall of the transverse guide plate 14. Due to the arc-shaped contour center of the transverse eccentric guide plate ( Figure 8 , Figure 9 (O1) is located at the center of the drive sprocket 21 ( Figure 8 , Figure 9 Above the O2), the counterweight 43, following the arc path of the drive sprocket 21, is obstructed by the contact transverse guide plate 14. This causes the counterweight 43 to no longer remain at its lowest point due to greater gravity, but is gradually "flipped" backward by the contact transverse guide plate 14, thereby causing the receiving bowl 42 to flip so that its opening faces forward (see...). Figure 8 In process C1, the heated and gelatinized rice flour is poured into the discharge receiving conveyor belt (not shown in the figure).

[0034] As the conveyor chain 2 continues to move, the counterweight 43 disengages from the leading edge of the top wall of the transverse guide plate 14 (see...). Figure 9 At this point, due to inertia, the receiving bowl 42 will continue to flip forward, causing the counterweight 43 to flip past its highest point, and then flip back to its lower position (see...). Figure 9 (Process C2) The above process avoids interference contact between the receiving bowl 42 and the leading edge of the top wall of the transverse guide plate 14.

[0035] The chain conveyor rice flour steamer of this invention enables large-scale heating and gelatinization of raw rice flour, improving production efficiency. The two-layer feeding section 23 is rationally laid out, fully utilizing steam vertically to maximize energy utilization and achieve green energy saving.

[0036] The counterweight 43 is designed so that the receiving bowl 42 faces upward during horizontal conveying, which prevents rice noodles from spilling and makes feeding easier.

[0037] The lateral guide plate 14 enables the receiving bowl 42 to quickly discharge material when turning forward, eliminating the need for additional discharge mechanisms and making the production process more continuous and efficient.

[0038] The limiting sprocket 31 engages with the lower side of the feeding section 23 and the return section 24 to prevent the feeding section 23 and the return section 24 from disengaging from the chain plate 13.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
