An extruder for rice noodle production

Abstract

This utility model relates to the field of rice noodle processing technology and discloses an extruder for rice noodle production, including a base. A housing and a water tank are fixedly installed on the upper surface of the base. A conveying chamber is opened inside the housing, and an extrusion conveying assembly is arranged inside the conveying chamber. An inlet is opened on the upper left side of the housing, and an outlet is opened on the right side of the housing, with an extrusion head corresponding to the outlet on the right side of the housing. In this rice noodle extruder, after the raw material is heated and shaped, it falls into the water tank for cooling. A preheating assembly and a circulating pump extract water from the water tank and transport it to a heat exchange chamber via an inlet pipe to preheat the raw material inside the conveying chamber. This reduces the operating power of the temperature-controlled heating plate. The water after heat exchange flows back to the water tank through a return pipe, achieving water resource recycling. This also reduces the frequency of water replacement due to temperature increases, improves heat utilization, and meets the needs of green production processing.

Description

Technical Field

[0001] This utility model relates to the field of rice noodle processing technology, and more specifically to an extruder for rice noodle production. Background Technology

[0002] Rice noodles are made from rice. They are long and thin with a circular cross-section, white in color, and have a good elasticity. Rice noodles are usually made by pressing and extruding, which requires pressing and extruding equipment to extrude and shape the rice noodles.

[0003] Currently, after rice noodles are extruded and heated using an extruder, they are usually placed in water to cool and solidify to ensure the shape and texture of the noodles. However, continuous extrusion processing causes the water to heat up, requiring water replacement. This water replacement increases water consumption and wastes heat in the water, which does not meet the requirements of green production and processing.

[0004] In view of this, the present invention proposes an extruder for rice noodle production. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an extruder for rice noodle production to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an extruder for rice noodle production, including a base, with a housing and a water tank fixedly installed on the upper surface of the base respectively. The housing has a conveying chamber inside, and an extrusion conveying assembly is provided inside the conveying chamber. A feed inlet is provided on the upper left side of the housing, and a discharge outlet is provided on the right side of the housing. An extrusion head is provided on the right side of the housing corresponding to the discharge outlet. A forming hole is provided on the surface of the extrusion head, and a temperature-controlled heating plate is embedded inside the extrusion head. The forming hole corresponds to the upper opening of the water tank, and a preheating assembly is provided in the water tank corresponding to the housing.

[0007] The preheating assembly includes a circulating pump fixedly installed at a high position on the front of the water tank. The inlet end of the circulating pump extends to a high position inside the water tank. An inlet pipe is fixedly installed at the outlet end of the circulating pump. A jacket is fixedly installed on the outer wall of the casing. A heat exchange chamber is reserved between the jacket and the casing. A return water pipe is embedded at a low position on the back of the water tank. The outlet end of the inlet pipe and the inlet end of the return water pipe are both connected to the heat exchange chamber.

[0008] Furthermore, a control panel is fixedly mounted on the surface of the housing, and the control panel is electrically connected to an external power source via wires.

[0009] As a further description of the above technical solution: by setting up a control panel, operators can easily control various functions of the extruder, improving the ease of operation and intelligence of the equipment.

[0010] Furthermore, the housing has several heat-conducting wires fixedly installed inside the heat exchange cavity, and the heat-conducting wires are evenly distributed in a circumferential array inside the heat exchange cavity.

[0011] As a further description of the above technical solution: by setting heat-conducting wires, the heat exchange area can be increased, thereby improving the effect of water preheating the raw materials.

[0012] Furthermore, a feed hopper is provided on the top of the housing corresponding to the feed inlet, and a first reduction motor is fixedly installed on the top of the feed hopper. The output shaft of the first reduction motor extends into the interior of the feed hopper and a stirring rod is fixedly installed thereon.

[0013] As a further description of the above technical solution: by setting up a feeding hopper, the operator can easily pour the rice noodle raw materials into the feeding hopper. At the same time, the first reduction motor drives the stirring rod to stir the raw materials, avoiding blockage inside the feeding hopper and ensuring that the raw materials can enter the conveying chamber evenly and stably.

[0014] Furthermore, the extrusion conveying assembly includes a second reduction motor fixedly installed at the left end of the housing. The output shaft of the second reduction motor extends into the interior of the conveying cavity and is coaxially fixedly mounted with a shaft rod. An auger blade is fixedly mounted on the surface of the shaft rod.

[0015] As a further description of the above technical solution: by setting up an extrusion conveying assembly, the second reduction motor drives the shaft and auger blade to rotate, extruding and conveying the raw material, ensuring that the raw material can be stably heated and formed through the extrusion head.

[0016] Furthermore, a protective mesh cover is provided on the inner wall of the water tank corresponding to the liquid inlet end of the circulation pump, and a drain pipe is embedded in the lower right side of the water tank.

[0017] As a further description of the above technical solution: by setting up a protective net, the rice noodles in the water can be intercepted, preventing the rice noodle products from entering the circulation pump and causing damage. By setting up a drain pipe, the operator can easily drain the water in the tank for cleaning or water replacement.

[0018] Furthermore, a water supply flat pipe is fixedly installed on the inner left wall of the water tank. The inner cavity of the water supply flat pipe is connected to the return water pipe. Several nozzles are evenly embedded on the upper surface of the water supply flat pipe, which is inclined to the right.

[0019] As a further description of the above technical solution: by setting up a water delivery flat pipe and a nozzle, the water after heat exchange can be evenly sprayed into the water tank to cool the rice noodles, thereby improving the cooling efficiency and cooling effect. In addition, since the nozzle is tilted to the right, it can push the rice noodles to the right, preventing the rice noodles from piling up on the left side of the water tank.

[0020] The technical effects and advantages of this utility model are as follows: 1. Compared with existing technologies, this extruder for rice noodle production adds raw materials to the conveying chamber inside the machine casing. The raw materials are conveyed by the extrusion conveying assembly. The raw materials are heated and shaped when passing through the forming hole of the extruder head, and then fall into the water tank for cooling. By setting up a preheating assembly, a circulating pump draws water out of the water tank and uses the liquid inlet pipe to transport the water to the heat exchange chamber to preheat the raw materials in the conveying chamber. This reduces the working power of the temperature-controlled electric heating plate. The water after heat exchange flows back to the water tank through the return water pipe, realizing the recycling of water resources. At the same time, it reduces the frequency of water replacement caused by water temperature rise and improves the heat utilization rate, meeting the needs of green production and processing.

[0021] 2. Compared with existing technologies, this extruder for rice noodle production, with its control panel, allows operators to easily control various functions of the extruder, improving the ease of operation and intelligence of the equipment; the addition of heat-conducting wires increases the heat exchange area, thereby enhancing the preheating effect of water on the raw materials; and the feeding hopper allows operators to easily pour the rice noodle raw materials into it, while the first reduction motor drives the stirring rod to stir the raw materials, preventing blockage inside the feeding hopper and ensuring that the raw materials can enter the conveying chamber evenly and stably.

[0022] 3. Compared with existing technologies, this extruder for rice noodle production, by setting up an extrusion conveying assembly, uses a second reduction motor to drive the shaft and auger blades to rotate, extruding and conveying the raw materials, ensuring that the raw materials can be stably heated and formed through the extrusion head; by setting up a protective net cover, the rice noodles in the water can be intercepted, preventing the rice noodle products from entering the circulating pump and causing damage; by setting up a drain pipe, the operator can easily drain the water in the tank for cleaning or water replacement; by setting up a water delivery flat pipe and nozzles, the heated water can be evenly sprayed inside the tank to cool the rice noodles, improving cooling efficiency and effect; and because the nozzles are tilted to the right, the rice noodles can be pushed to the right, preventing them from accumulating on the left side of the tank.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The extruder for rice noodle production involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1 to 4 This utility model provides an extruder for rice noodle production, including a base 1, with an organic shell 2 and a water tank 3 fixedly installed on the upper surface of the base 1.

[0027] A control panel 11 is fixedly mounted on the surface of the casing 2. The control panel 11 is electrically connected to an external power source via wires.

[0028] By setting up the control panel 11, operators can easily control various functions of the extruder, improving the ease of operation and intelligence of the equipment.

[0029] The housing 2 has a conveying cavity inside, and a compression conveying assembly is installed inside the conveying cavity.

[0030] The extrusion conveying assembly includes a second geared motor 16 fixedly installed at the left end of the housing 2. The output shaft of the second geared motor 16 extends into the interior of the conveying chamber and is coaxially fixedly mounted with a shaft 17. An auger blade 18 is fixedly mounted on the surface of the shaft 17.

[0031] By setting up an extrusion conveying assembly, the second reduction motor 16 is started to drive the shaft 17 and the auger blade 18 to rotate, which can extrude and convey the raw materials.

[0032] A feed inlet is provided on the upper left side of the casing 2.

[0033] The top of the casing 2 is provided with a feeding hopper 13 corresponding to the feeding port. A first reduction motor 14 is fixedly installed on the top of the feeding hopper 13. The output shaft of the first reduction motor 14 extends into the interior of the feeding hopper 13 and a stirring rod 15 is fixedly installed thereon.

[0034] By setting up the feeding hopper 13, the operator can easily pour the rice noodle raw materials into the feeding hopper 13. At the same time, the first reduction motor 14 drives the stirring rod 15 to stir the raw materials, avoiding blockage inside the feeding hopper 13 and ensuring that the raw materials can enter the conveying chamber evenly and stably.

[0035] The right end of the casing 2 is provided with a discharge port, and the right end of the casing 2 is provided with an extrusion head 4 corresponding to the discharge port. The surface of the extrusion head 4 is provided with a forming hole 5, and the interior of the extrusion head 4 is fitted with a temperature-controlled heating plate 6. The forming hole 5 corresponds to the upper opening of the water tank 3.

[0036] When the extruder for rice noodle production is in use, the raw materials are fed into the conveying chamber inside the machine housing 2 through the feeding hopper 13. The raw materials are conveyed by the extrusion conveying assembly. When the raw materials pass through the forming hole 5 of the extrusion head 4, they are heated and shaped by the temperature-controlled electric heating plate 6, and then fall into the water tank 3 for cooling and shaping.

[0037] The water tank 3 is equipped with a preheating component corresponding to the casing 2.

[0038] The preheating assembly includes a circulation pump 7 fixedly installed at the high front of the water tank 3. The inlet end of the circulation pump 7 extends to the high interior of the water tank 3. An inlet pipe 8 is fixedly installed at the outlet end of the circulation pump 7. A jacket 9 is fixedly installed on the outer wall of the housing 2. A heat exchange chamber is reserved between the jacket 9 and the housing 2. A return water pipe 10 is embedded at the low back of the water tank 3. The outlet end of the inlet pipe 8 and the inlet end of the return water pipe 10 are both connected to the heat exchange chamber.

[0039] It is worth noting that during the rice noodle forming process, a preheating component is set up, the circulating pump 7 is started to extract water from the water tank 3, and the water is transported to the heat exchange chamber through the liquid inlet pipe 8 to preheat the raw materials inside the conveying chamber. This reduces the working power of the temperature-controlled electric heating plate 6, and the water after heat exchange flows back to the water tank 3 through the return water pipe 10, realizing the recycling of water resources. At the same time, it reduces the frequency of water replacement caused by water temperature rise and improves the heat utilization rate, meeting the needs of green production and processing.

[0040] The housing 2 has several heat-conducting wires 12 fixedly installed inside the heat exchange cavity. The heat-conducting wires 12 are evenly distributed in a circumferential array inside the heat exchange cavity.

[0041] By setting the heat-conducting wire 12, the heat exchange area can be increased, thereby improving the effect of water preheating the raw materials.

[0042] A protective mesh cover 19 is installed on the inner wall of the water tank 3 corresponding to the liquid inlet end of the circulating pump 7, and a drain pipe 20 is embedded in the lower right side of the water tank 3.

[0043] By setting up a protective net cover 19, the rice noodles in the water can be intercepted, preventing the rice noodle products from entering the circulation pump 7 and causing damage. By setting up a drain pipe 20, the operator can easily drain the water in the water tank 3 for cleaning or water replacement.

[0044] A water supply flat pipe 21 is fixedly installed on the inner left wall of the water tank 3. The inner cavity of the water supply flat pipe 21 is connected to the return water pipe 10. Several nozzles 22 are evenly embedded on the upper surface of the water supply flat pipe 21, which is inclined to the right.

[0045] It is worth noting that by setting up the water delivery pipe 21 and the nozzle 22, the water after heat exchange can be evenly sprayed into the water tank 3 to cool the rice noodles, which improves the cooling efficiency and cooling effect. In addition, since the nozzle 22 is tilted to the right, it can push the water and rice noodles to the right, avoiding the accumulation of rice noodles on the left side of the water tank 3.

[0046] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
