Description
Technical Field
[0001] This utility model relates to the field of mixer technology, specifically a raw material mixer for rice noodle production. Background Technology
[0002] The production of rice noodles mainly includes the following steps: weighing raw materials, soaking, washing, grinding, ingredient mixing, weighing rice, soaking rice, washing rice, grinding, ingredient mixing, and extrusion. Rice flour is weighed as the main ingredient, and starch is weighed as the auxiliary ingredient. The rice flour and starch are then mixed together and stirred until evenly combined before being extruded to make rice noodles.
[0003] For existing vertical mixers, dead zones are easily formed at the bottom, where materials accumulate and cannot be mixed. For example, in a rice noodle raw material mixing device proposed in document CN221333723U, paragraph
[0031] describes two mixing rods fixedly sleeved on two rotating shafts. The shape of the mixing rods is consistent with the mounting groove. When the mixing motor is started, it drives the rotating rod to rotate. Under the action of centrifugal force, the mixing rods leave the inside of the mounting groove and rotate with the rotating rod, thereby mixing the raw materials inside the tank. However, the mixing rods cannot effectively mix the materials at the bottom of the equipment, reducing the mixing efficiency. Therefore, we propose a raw material mixer for rice noodle production.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1 to 5 This utility model provides a technical solution: a raw material mixer for rice noodle production, including a tank 1. The bottom edge of the tank 1 is provided with multiple support legs 9, which are supported on the ground or fixed to the ground. The top of the tank 1 is provided with a feeding trough 2. Setting the feeding trough 2 on the top side of the tank 1 allows the tank 1 to store more rice noodle raw materials. The top of the feeding trough 2 is sealed by a detachable cover plate 3. The cover plate 3 is connected to the opening of the feeding trough 2 by a latch, which makes it convenient to open or close the cover plate 3.
[0024] Next, a discharge cylinder 10 is coaxially provided at the bottom of the tank body 1. An end cover 8 is detachably installed at the bottom of the discharge cylinder 10. The edges of the two are fastened by bolts. A discharge valve 11 is provided at the bottom side of the discharge cylinder 10. A spiral shaft 16 is provided inside the discharge cylinder 10. The top of the spiral shaft 16 extends into the tank body 1. The part of the spiral shaft 16 extending into the tank body 1 does not exceed one-third of the height of the tank body. The lower end of the spiral shaft 16 is rotatably connected to the bottom of the discharge cylinder 10. Specifically, the bottom of the spiral shaft 16 is rotatably installed at the center of the end cover 8. The two are connected by a bearing and a sealing assembly. Because the end cover 8 is easy to disassemble, the spiral shaft 16 can also be removed from the discharge cylinder 10, which is convenient for maintenance of the spiral shaft 16.
[0025] The tank body 1 is also equipped with a stirring shaft 12. The stirring shaft 12 is located above the spiral shaft 16 and there is a gap between the ends of the two to avoid contact between the ends. The upper end of the stirring shaft 12 is rotatably connected to the top of the tank body 1. The top of the tank body 1 is detachably equipped with a sealing cover 4. The sealing cover 4 is fastened to the edge of the top of the tank body 1 by bolts. Specifically, the top of the stirring shaft 12 is rotatably installed at the center of the sealing cover 4. In this way, when the sealing cover 4 and the stirring shaft 12 are disassembled as a whole, it is convenient to maintain the stirring shaft 12.
[0026] A stirring device is provided on the surface of the stirring shaft 12. For example... Figure 3 and Figure 4 As shown, the stirring device includes stirring blades 13 arranged around the stirring shaft 12. The stirring blades 13 are located on one side of the inner wall surface of the tank body 1, and the bottom of the stirring blades 13 is provided with a downwardly extending extension 14. The bottom of the tank body 1 has a conical structure, which allows the raw materials to be concentrated along the inclined surface. The extension 14 is placed above the surface of the conical structure. The extension 14 and the stirring blades 13 are respectively connected to the stirring shaft 12 through support rods 15. The extension 14 and the stirring blades 13 are inclined. The extension 14 is clearance-fitted with the surface of the conical structure, and the stirring blades 13 are clearance-fitted with the inner wall of the tank body 1.
[0027] The advantage of tilting the stirring blade 13 is that it can not only scrape the raw material on the inner wall of the tank 1, but also the extension 14 can scrape the material on the surface of the conical structure. Moreover, the tilted extension 14 can scoop up the raw material and advance it toward the discharge cylinder 10.
[0028] like Figure 3 and Figure 5 As shown, multiple spiral stirring blades 17 are also provided around the stirring shaft 12. The spiral stirring blades 17 are located between the stirring blades 13 and the stirring shaft 12. The spiral stirring blades 17 are respectively arranged on the support rod 15. The spiral stirring blades 17 rotate in the opposite direction to the blades on the surface of the spiral shaft 16, but they can also be arranged in the same direction. The spiral stirring blades 17 and the stirring blades 13 rotate at the same time, which can make the material tumble more violently.
[0029] like Figure 1 As shown, a drive device is also provided on the side of the tank 1, and the bottom of the spiral shaft 16 and the top of the stirring shaft 12 are both driven to rotate by the drive device. The drive device includes a dual-shaft motor 7 vertically mounted on the side of the tank 1. The two shafts of the dual-shaft motor 7 are respectively equipped with drive shafts 6, and the ends of the two drive shafts 6 extend to the top of the tank 1 and the lower end of the discharge cylinder 10, respectively. Pulleys are respectively installed at the ends of the two drive shafts 6 away from the dual-shaft motor 7, at the top of the stirring shaft 12, and at the bottom of the spiral shaft 16, and the pulleys are connected by belts. In this application, both the stirring shaft 12 and the spiral shaft 16 are driven to rotate by the dual-shaft motor 7, and they share a single drive device.
[0030] Specifically, when the spiral shaft 16 rotates, due to the spiral structure of the blades on the surface of the spiral shaft 16, it can transport the raw material located at the bottom of the tank 1 upward at a certain speed. The rising raw material comes into contact with the stirring device, that is, the rising material can come into contact with the spiral stirring blade 17, stirring blade 13 and extension 14, so that the raw material in the tank 1 continuously surges upward from the spiral shaft 16 and is stirred by the spiral stirring blade 17, stirring blade 13 and extension 14, which can make the raw material mix quickly.
[0031] In practical applications, different transmission ratios can be achieved by adjusting the size of the belt, which in turn can control the rotation speed of the mixing device and the spiral shaft 16. The rotation speed of the spiral shaft 16 can be set to be faster than that of the mixing device, allowing the raw materials to rise at a faster speed.
[0032] Furthermore, in order to avoid reducing strength due to excessive length of the drive shaft, the ends of the two drive shafts 6 away from the dual-axis motor 7 are respectively rotatably installed in the support arm 5. The ends of the support arm 5 away from the drive shafts 6 are respectively connected to the tank body 1 and the discharge cylinder 10. The support arm 5 is specifically installed on the sealing cover 4.
[0033] Based on the above embodiments, it should be further explained that when stirring, the spiral shaft 16 drives the raw material upward to increase the stirring speed, while when discharging, the spiral shaft 16 rotates in the opposite direction, that is, the dual-shaft motor is controlled to reverse, so that the spiral shaft 16 can convey the material downward, while the stirring blades 13 and the extension 14 can move the raw material and accelerate the discharge of the raw material.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
