Description

Technical Field

[0001] This invention belongs to the field of rice noodle processing technology, and more specifically, relates to a processing equipment for rice noodle extrusion molding. Background Technology

[0002] Currently, rice noodles are rice products made from rice through processes such as soaking, steaming, and pressing. There are many varieties of rice noodles, which can be divided into flat rice noodles, square rice noodles, wavy rice noodles, silver thread rice noodles, wet rice noodles, and dry rice noodles. Their production processes are largely similar, generally including: rice, washing, soaking, grinding, steaming, extrusion molding, re-steaming, cooling, drying, packaging, and finished product.

[0003] Chinese Patent Publication No. CN114431394A discloses a forming device for rice noodle production, including a device body with an extrusion cylinder on the device body. Several connecting rods connect the extrusion cylinder to the device body. A discharge mechanism is connected to one side of the extrusion cylinder. The discharge mechanism includes an installation cylinder connected to one end of the extrusion cylinder. A push plate is located inside the installation cylinder, and several grooves are carved within the installation cylinder. A slider is located within each groove and connected to the push plate. A connecting pipe is connected to the push plate, and several forming holes are carved within the push plate. The connecting pipe communicates with the forming holes. Several sliding rods are located within each groove. This invention, through the corresponding structural design on the rice noodle forming device, effectively reduces the occurrence of rice noodles sticking together during extrusion, effectively reduces the probability of clogging the discharge port during rice noodle extrusion, effectively improves the forming effect of the rice noodle forming device, and effectively reduces the waste of rice noodle raw materials.

[0004] While the aforementioned patent allows for the extrusion of rice noodles, the following issues arise: During the extrusion process, the temperature of the rice noodle raw material gradually decreases due to continuous conveying, causing it to stick to the inner wall of the conveyor. Over time, this can lead to internal blockages, making it impossible to maintain a balanced temperature during rice noodle conveying. Furthermore, the device cannot regulate the extrusion volume, ensuring consistent rice noodle content and resulting in defects that affect quality. It also lacks automatic detection and adjustment, exhibiting poor conveying stability. Additionally, the dies used in the extrusion process are prone to interference, causing the rice noodles to clump and stick together, compromising independent conveying and severely impacting subsequent rice noodle processing. Summary of the Invention

The second flow divider plate is provided with multiple flow dividers, which are equidistantly distributed. A double-layer guide plate is provided below the second flow divider plate, and multiple guide holes are provided on the guide plate. The guide holes are oblong. An extrusion template is welded and sealed at the bottom of the extrusion die. A row of extrusion holes is provided on the extrusion template, through which the rice noodle raw material is evenly extruded.

[0007] As an optional embodiment of the present invention, the drive assembly includes a motor base, which is fixed on the frame. A gear reducer is mounted on the motor base. A main pulley is provided at one end of the gear reducer, and a secondary pulley is provided directly above the main pulley. The secondary pulley is assembled at one end of the rotating shaft, and the secondary pulley and the main pulley are connected for transmission via a synchronous belt.

[0008] As an optional embodiment of the present invention, the gear reducer is model RCW47-5.02-Y2.2-M1.

[0009] As an optional embodiment of the present invention, the extrusion screw is divided into two sections: one section has a pitch of 48 mm and a length of 432 mm, and the other section has a pitch of 24 mm and a length of 216 mm.

[0010] As an optional embodiment of the present invention, a heating screw sleeve is also provided on the extrusion channel.

[0013] This invention provides a processing device for rice flour extrusion molding, which has the following beneficial effects:

[0014] The extrusion screw inside the extrusion channel is driven by a rotating shaft within the bearing housing. Simultaneously, a servo motor drives a planetary reducer, and the adjusting screw continuously rotates to balance the extrusion volume of rice noodles. A heated screw sleeve heats the extrusion channel, improving the stability of the extrusion process and preventing sticking to the inner wall. An adjusting seat allows the extrusion chamber to gradually retract, and the extruded material is conveyed to the feed inlet via the adjusting screw. A flow detector monitors the extrusion volume. When the initial volume is stable, the adjusting screw maintains balance. If the initial volume is too high or too low, the flow detector transmits a signal to the servo motor, which decelerates or accelerates the adjusting screw to ensure balanced extrusion.

[0015] Setting up a flat extrusion die allows the rice noodle raw materials to be evenly distributed and guided, and finally extruded from the extrusion template, ensuring that the rice noodles are evenly and independently extruded and forming, and avoiding the rice noodles from sticking together and clumping.

The extrusion adjustment mechanism can control the extrusion amount of rice noodle raw materials.

[0026] The extrusion adjustment mechanism includes an adjustment seat 11. A motor flange 12 is mounted on one side of the adjustment seat 11. A planetary reducer 13 is mounted on one end of the motor flange 12. The planetary reducer 13 is model FPGA080-70. A servo motor, model ECMA-C20604ES, is also mounted on one end of the planetary reducer 13. An extrusion chamber is provided inside the adjustment seat 11. The extrusion chamber is conical with a gradually decreasing opening diameter. One end of the extrusion chamber is connected to the extrusion channel 7, and the other end of the extrusion channel 7 is connected to the adjustment chamber 112.

[0027] The extrusion mold 14 is flat, and an adapter 141 is welded to the top of the extrusion mold 14 for connecting the sealing adapter pipe 15.

[0028] The specific usage and function of this embodiment are as follows: First, the gear reducer 3 is started, and the main pulley 4 rotates through the synchronous belt 5 and the auxiliary pulley 601. At this time, the rotating shaft in the bearing seat 6 drives the extrusion screw 701 in the extrusion channel 7 to rotate. Simultaneously, the servo motor is started to drive the planetary reducer 13 to operate, and the adjusting screw 113 rotates continuously. At this time, the feeding operation is carried out. The rice flour raw material enters the extrusion channel 7 through the feeding hopper 8. The heating screw sleeve 9 will heat the extrusion channel 7 to improve the stability of the extrusion conveying and prevent sticking to the inner wall. After entering the adjusting seat 11, it gradually retracts in the extrusion chamber. The adjusting screw 113 is fed into the transfer pipe 15 at the feeding port. The extrusion volume is detected by the flow detector 151. When the basic volume is stable, the adjusting screw 113 rotates in a balanced manner. If the basic volume is too large or too small, the flow detector 151 will transmit a signal to the servo motor to adjust the adjusting screw 113 by decelerating or accelerating it to ensure the extrusion balance. After entering the extrusion die 14, the flow is evenly distributed and guided. Finally, the rice noodles are extruded and discharged from the extrusion template 145 to ensure that the rice noodles are extruded and formed evenly and independently, and to avoid the rice noodles sticking together and tangling. After forming, it is conveyed to the next stage for fixed-length cutting.
