Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice cake production technology, specifically to an automated rice cake production equipment. Background Technology
[0002] In the production of rice cakes, rice flour is first ground and then steamed to cook it. The cooked rice flour is then kneaded thoroughly to achieve the ideal soft and chewy texture. The rice cake ingredients are then fed into an extruder and extruded through a specific mold to form continuous long strips of rice cakes, which are then cut into sections.
[0003] Currently, the production of rice cakes typically involves separate processes for grinding, steaming, and extrusion. This requires grinding rice flour into powder using grinding equipment, steaming the rice flour in a steamer to cook it, and finally extruding the dough into long strips using an extruder. The production process involves transferring rice flour between multiple production devices, which is cumbersome and has a low degree of automation, reducing production efficiency. Therefore, we propose an automated rice cake production equipment. Utility Model Content
[0004] The purpose of this invention is to provide an automated rice cake production equipment that allows for continuous execution of the rice flour grinding, steaming and cooking, dough mixing and kneading, and extrusion molding processes during rice cake production. This eliminates the need for multiple transfers of rice flour and dough, improving production convenience and efficiency, and enhancing automation. It solves the problem that current rice cake production processes typically involve separate grinding, steaming, and extrusion. The rice flour needs to be ground into powder using grinding equipment, then steamed, and finally extruded into long strips using an extruder. This process requires transferring rice flour between multiple production devices, which is cumbersome, has low automation, and reduces production efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated rice cake production equipment, including an extruder barrel, a feed pipe fixedly connected to one side of the upper surface of the extruder barrel, and a grinding mill fixedly installed on the upper surface of the feed pipe, a rotating shaft rotatably installed inside the extruder barrel, a first spiral blade and a second spiral blade sequentially fixedly installed on the outer surface of the rotating shaft, with the second spiral blade located below the feed pipe, the rotating shaft being hollow inside, and a steam pipe rotatably connected to the end of the rotating shaft near the feed pipe via a rotary joint, and a plurality of threaded countersunk holes evenly spaced along the spiral path of the second spiral blade on the outer surface of the rotating shaft, with a steam nozzle fixedly installed inside each threaded countersunk hole, and an extrusion die fixedly installed at the end of the extruder barrel opposite to the feed pipe.
[0006] Preferably, a transmission box is fixedly installed on the side of the extruder barrel near the steam pipe, and the rotating shaft passes through the transmission box. A rotating motor is fixedly installed on the outside of the transmission box, a motor gear is fixedly installed on the output end of the rotating motor, and a transmission gear is fixedly sleeved on the outer surface of the rotating shaft, and the motor gear and the transmission gear mesh with each other.
[0007] Preferably, an exhaust hood is fixedly installed on the upper surface of the extruder barrel at a position above the second helical blade, and an exhaust pipe is fixedly connected to the upper surface of the exhaust hood.
[0008] Preferably, the extrusion die and the extruder barrel are fixed together by bolts.
[0009] Preferably, a support frame is fixedly installed on the lower surface of the extruder barrel near both ends.
[0010] Preferably, the pitch of the first helical blade is smaller than the pitch of the second helical blade.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model, by setting up an extruder barrel, a grinding mill, a steam pipe, a rotating shaft, a steam nozzle, a first spiral blade, a second spiral blade, and an extrusion die, achieves continuous production of rice flour grinding, rice flour steaming and cooking, dough mixing and kneading, and extrusion forming during the rice cake production process. This eliminates the need for multiple transfers of rice flour and dough, improving production convenience and efficiency, and enhancing automation. Rice is added to the grinding mill, where it is ground into rice flour. The rice flour then falls into the extruder barrel through the feed pipe. Steam enters the rotating shaft through the steam pipe and is sprayed into the rice flour through the steam nozzle. During the rotation of the shaft, the second spiral blade primarily pushes and stirs the rice flour, ensuring full contact between the rice flour and steam, thus steaming and cooking the rice flour. The cooked rice flour is initially formed into a dough under the pressure of the second spiral blade. This dough is then further pushed and stirred by the first spiral blade, and finally formed into a long strip of rice cake through the extrusion die.
[0013] 2. By setting up an exhaust hood and an exhaust pipe, the steam inside the extruder barrel after contacting the rice flour is discharged into the exhaust hood and then discharged through the exhaust pipe, thereby venting the steam inside the extruder barrel. Attached Figure Description

A feed pipe 6 is fixedly connected to one side of the upper surface of the extruder barrel 1, and a mill 7 is fixedly installed on the upper surface of the feed pipe 6. Rice is ground into rice flour by the mill 7 and falls into the extruder barrel 1. A rotating shaft 15 is rotatably installed inside the extruder barrel 1, and the rotating shaft 15 and the extruder barrel 1 are rotatably connected by a bearing. A transmission box 2 is fixedly installed on the side of the extruder barrel 1 near the steam pipe 4, and the rotating shaft 15 passes through the transmission box 2. A rotating motor 3 is fixedly installed on the outside of the transmission box 2, and a motor gear 16 is fixedly installed at the output end of the rotating motor 3. A transmission gear 17 is fixedly sleeved on the surface, and the motor gear 16 and the transmission gear 17 mesh with each other. Both the motor gear 16 and the transmission gear 17 are located inside the transmission box 2. The rotating motor 3 drives the rotating shaft 15 to rotate through the meshing motor gear 16 and the transmission gear 17. The outer surface of the rotating shaft 15 is fixedly mounted with a first spiral blade 12 and a second spiral blade 14 in sequence. The second spiral blade 14 is located below the feed pipe 6. The pitch of the first spiral blade 12 is smaller than the pitch of the second spiral blade 14. The second spiral blade 14 mainly plays the role of pushing and stirring the rice flour inside the extruder barrel 1, and mainly plays the role of pushing and extruding the cooked rice flour dough.
[0021] The rotating shaft 15 is hollow inside. One end of the rotating shaft 15 near the feed pipe 6 is rotatably connected to a steam pipe 4 via a rotary joint 5. The end of the steam pipe 4 is connected to the output end of a steam boiler. High-temperature, high-pressure steam enters the interior of the rotating shaft 15 through the steam pipe 4 and the rotary joint 5. Several threaded countersunk holes 18 are evenly spaced along the spiral path of the second spiral blade 14 on the outer surface of the rotating shaft 15. A steam injection head 13 is fixedly installed inside each threaded countersunk hole 18. The steam inside the rotating shaft 15 is injected into the rice flour through the steam injection head 13. An extrusion die 10 is fixedly installed at one end of the extruder barrel 1 away from the feed pipe 6. The extrusion die 10 and the extruder barrel 1 are fixed together by bolts, which facilitates the disassembly and replacement of the extrusion die 10. An exhaust hood 9 is fixedly installed on the upper surface of the extruder barrel 1 above the second spiral blade 14. An exhaust pipe 8 is fixedly connected to the upper surface of the exhaust hood 9. The steam inside the extruder barrel 1 after contacting the rice flour is discharged into the exhaust hood 9 and discharged through the exhaust pipe 8. Support frames 11 are fixedly installed on the lower surface of the extruder barrel 1 near both ends.
[0022] In use, rice is added to the mill 7 and ground into rice flour. The rice flour then falls into the extruder cylinder 1 through the feed pipe 6. Steam enters the rotating shaft 15 through the steam pipe 4 and is sprayed into the rice flour through the steam nozzle 13. The rotating motor 3 drives the rotating shaft 15 to rotate through the meshing motor gear 16 and transmission gear 17. The rotating shaft 15 drives the second spiral blade 14 and the first spiral blade 12 to rotate. The second spiral blade 14 mainly pushes and stirs the rice flour, so that the rice flour and steam can come into full contact, thereby steaming and cooking the rice flour. The cooked rice flour is initially formed into rice balls under the extrusion action of the second spiral blade 14. Then the rice balls are further extruded and pushed by the first spiral blade 12 and further stirred and kneaded. Finally, it is formed into long strips of rice cake through the extrusion die 10.
