Description

Technical Field

[0001] This utility model belongs to the field of rice noodle machine technology, and relates to a small rice noodle machine. Background Technology

[0002] Rice noodles, as a specialty food and convenient food, are very popular in southern my country. The mass production process of large-scale rice noodle machines involves: soaking, fermentation, washing, grinding, mixing, spreading, steaming, extrusion (stretching), boiling, re-steaming, washing, draining, and finished product. The process is numerous and complicated. To suit small-batch, fast, and convenient production, various small rice noodle machines have been developed on the market. However, small rice noodle machines have certain shortcomings and areas for improvement in terms of fully cooking the rice noodles and disassembling and cleaning the extrusion screw after production.

[0003] For example, a Chinese patent with application number 2019204316923 discloses a convenient and multifunctional fresh wet rice noodle machine, including a cabinet and a feeding mechanism, an extrusion mechanism, an extrusion drive device, and a forming die head installed on the cabinet. It also includes a high-pressure heating device that can heat the rice paste in the extrusion mechanism. The high-pressure heating device includes a pressure holding chamber sleeved on the outside of the extrusion cylinder, a high-pressure steam engine connected to the pressure holding chamber by a steam outlet, and a water tank connected to the water inlet of the high-pressure steam engine by a pipe. The extrusion screw in this technical solution is not easy to disassemble, which affects the cleaning efficiency and causes the limitation of this technical solution. The high-pressure steam heating also poses certain safety hazards. Utility Model Content

[0034] like Figure 1-6 As shown, this utility model is a small rice noodle machine, including a support frame 6, a stirring device, a spiral feeding device, a screw heating and cooking extrusion device, and a forming mold device;

[0035] The mixing device includes a rice flour mixing drum 73; the screw feeding device includes a first motor 8, a feeding sleeve 71 and a feeding screw 72.

[0036] The screw heating and curing extrusion device includes an extrusion screw 63, a sleeve 62 and an annular heater 61; the sleeve 62 is provided outside the extrusion screw 63, the annular heater 61 is provided outside the sleeve 62, and a flange 64 for fixing the rice noodle forming mold is provided below the sleeve 62.

[0037] The bracket 6 is equipped with a bearing seat 66, and the outer shell of the bearing seat 66 is fixedly connected to the upper end of the sleeve 62 by an internal hex screw 65.

[0038] The support 6 is provided with a feeding sleeve 71. One end of the feeding sleeve 71 is provided with a rice noodle mixing drum 73 and a first motor 8. The first motor 8 is installed on the support 6. The other end of the feeding sleeve 71 is connected to the sleeve 62. The feeding sleeve 71 is provided with a feeding screw 72, which, driven by the first motor 8, feeds the rice noodles in the rice noodle mixing drum 73 into the sleeve 62.

[0039] Preferably, the shaft inside the bearing housing 66 is provided with a hollow spline shaft 67; the hollow spline shaft 67 is engaged with the upper end of the extrusion screw 63 to drive the extrusion screw 63 to rotate.

[0040] Preferably, the extrusion screw 63 is installed vertically, which facilitates disassembly and cleaning. Because the extrusion screw 63 is a vertical device, the flange 64 can be removed by removing the hex socket screw 65, and the extrusion screw 63 can be quickly removed for cleaning, thereby improving the cleaning efficiency of the extrusion screw 63.

[0041] Preferably, the bracket 6 is provided with a second motor 81, the output end of the second motor 81 is engaged with the hollow spline shaft 67 to drive the hollow spline shaft 67 to rotate, and drive the rice flour extrusion screw 63 to rotate.

[0042] The output end of the second motor 81 is equipped with a first pulley, and the hollow spline shaft 67 is equipped with a second pulley via a shaft. The second pulley and the first pulley are connected by a belt to drive the hollow spline shaft 67 to rotate, and drive the extrusion screw 63 to rotate. Under the drive of the second motor 81, the extrusion screw 63 rotates and, together with the heating of the annular heater 6 and frictional heat generation, forms a uniform cooking of the rice flour. The annular heating and frictional heat generation are adjustable and controllable by the temperature controller and the speed of the extrusion screw.

[0043] Preferably, the extrusion screw 63 is hollow to reduce its weight. The extrusion screw 63 includes an installation section 5, a friction heating section 4, a pressurizing section 3, a heating section 2, and a receiving section 1. The installation section 5 is fitted with the hollow spline shaft 67. The lower end of the friction heating section 4 is connected to the rice noodle forming mold device. The forming mold device is used for rice noodle forming.

[0044] The rice noodles pass through the receiving section 1, heating section 2, pressurizing section 3, friction heating section 4, and forming mold device. The heating section 2 can extend the travel path of the rice noodles, disperse and heat them, so that the rice noodles are heated evenly and quickly, and cooked well. At the same time, it is energy-saving and efficient, and ultimately improves the quality of the rice noodles.

[0045] The rice noodle extrusion screw 63 includes a first connecting rod and a first spiral blade 11. The upper end of the first connecting rod is connected to the mounting section 5, and the first spiral blade 11 is disposed on the outside of the first connecting rod. The first spiral blade 11 is used to drive the rice noodles to move downwards gradually.

[0046] The first connecting rod is provided with a first stop bar 12, which is located between the two blades of the first spiral blade 11 and is less than the depth of the first spiral blade 11. By setting the first stop bar 12, the rice noodles will become thinner when passing the second stop bar 12, which further improves the degree of cooking of the rice noodles during operation.

[0048] The partition block 21 causes the rice noodles to disperse from a single strand into multiple strands during operation, which is conducive to the uniform cooking of the rice noodles; while the guide block 22 causes the rice noodles to move up and down in a spiral on the second connecting rod, which extends the running path of the rice noodles and further helps the rice noodles to cook evenly.

[0049] The pressurizing section 3 includes a third connecting rod, a second spiral blade 31, and a second stop bar 32; the lower end of the second connecting rod is provided with a third connecting rod, the outer side of the third connecting rod is provided with a second spiral blade 31, and the third blade of the second spiral blade 31 is provided with a second stop bar 32; the setting of the second stop bar 32 allows the rice noodles to only run in the pointing direction; while the setting of the second spiral blade 31 allows the rice noodles to run onto the friction heating section 4, so as to facilitate the extrusion of the rice noodles.

[0050] Preferably, the forming mold device is a friction heating section 4. The grooves distributed circumferentially along the axial direction of the friction heating section 4 are staggered with the grooves distributed radially around it. Furthermore, the grooves distributed circumferentially along the axial direction alternately connect with and disconnect from the pressure section 3. The rice noodles pass through, intersect, and mix within the circumferentially and radially distributed grooves of the friction heating section 4, generating frictional heat and further ensuring uniform cooking of the rice noodles, thus improving the extrusion quality.

[0051] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
