Description

Technical Field

[0001] The invention relates to the technical field of sweet potato vermicelli production, and in particular to a sweet potato vermicelli cutting device and method. Background Art

[0002] Sweet potato vermicelli is a green and healthy food made from sweet potato starch in the form of strips or filaments. When making handmade sweet potato vermicelli, a filament extruder is used to extrude the sweet potato starch slurry into a thread shape, which is then directly dropped into boiling water and cooked to form vermicelli. However, in modern industrial production, in order to improve production efficiency, the production process of sweet potato vermicelli has also changed. The vermicelli skin is first produced and then cut into vermicelli. The slurry is directly transported in a belt-like manner to form a slurry belt of a certain thickness. The slurry is directly steamed in a steamer to form a vermicelli skin state, which is then aged at low temperature. The vermicelli skin is then cut into filaments by a cutting mechanism to form vermicelli. For example , a Chinese invention patent with authorization announcement number CN108450924A discloses a new type of vermicelli production process, which discloses the following steps: S1: mixing slurry; S2: spreading slurry; S3: maturation; S4: aging: the maturated vermicelli is automatically cooled to room temperature under dry and ventilated conditions, and then the vermicelli is frozen and aged, the freezing time is 1.5-2.5 hours, and the freezing temperature is 0-5 degrees Celsius; S5: shredding; S6: drying and forming; wherein the current vermicelli skin is cut into vermicelli using multiple uniformly arranged cutting blades, and the vermicelli skin is formed into vermicelli after passing through multiple uniformly arranged cutting blades, but this cutting method has the following defects: When the rice noodles pass through the cutting knife, if part of the cutting knife is blunt, it is easy to cause the rice noodles at that position to pass unsmoothly and form lumps, which requires a high degree of sharpness of the cutting knife; in addition, the rice noodles after aging still have a certain viscosity, and the gaps between the vermicelli formed after passing through the cutting knife are small and will contact each other, resulting in some vermicelli sticking together in the finished product.

After passing through the cutting mechanism 4, it is cut under the pressure of the strip knife 43 to form vermicelli of a specified length.

[0027] Example 4: Please refer to Figure 1-9 , which is the fourth embodiment of the present invention. This embodiment is based on the above three embodiments. When the present invention is used, according to the required thickness of the sweet potato vermicelli, a slitting mechanism 3 with an annular cutting blade 34 with corresponding spacing is selected, the slitting mechanism 3 is installed on the two guide rods 24, and the locking nut 26 is tightened to fix it. According to the required length of the sweet potato vermicelli, the pneumatic push rod 619 on the speed change assembly 6 is adjusted to change the rotation speed of the driven long shaft 63, and then the rotation speed of the cutting roller 42 of the cutting mechanism 4 is adjusted; the cooked and aged rice noodles pass through the transverse roller 32 and the extrusion roller 33 on the slitting mechanism 3, and the transverse roller 32 and the extrusion roller 33 rotate to transport the rice noodles. Under the action of the annular cutting blade 34, the rice noodles are cut into vermicelli, and the rice noodles are squeezed by the extrusion ring 35, so that the cut vermicelli have gaps between each other, and the vermicelli falls and passes between the separation blades 39 to ensure that the vermicelli maintains a certain distance; the vermicelli formed after slitting falls onto the guide conveyor belt 29, and the guide conveyor belt 29 The rice noodles are transported to the conveyor belt 15, and after passing through the cutting mechanism 4, they are cut under the pressure of the strip knife 43 to form rice noodles of a specified length. The present invention cuts the rice noodles into rice noodles through the slitting mechanism 3. The slitting mechanism 3 uses a plurality of evenly arranged annular cutting blades 34 to cut the rice noodles to form rice noodles. The cutting is carried out in a rotating manner. The rice noodles are contacted and transported by the annular cutting blades 34 and the extrusion rollers 33, which is convenient for passing through the position of the annular cutting blades 34, and the sharpness of the annular cutting blades 34 is not required to be high. Moreover, during cutting, the rice noodles are squeezed on both sides by the annular cutting blades 34 and the extrusion rings 35 to complete the slitting. Under the action of the extrusion rings 35, the rice noodles move toward one side of the annular cutting blades 34, so that the spacing between the cut rice noodles is increased, and the rice noodles fall through a plurality of separation blades 39. Since the separation blades 39 are narrow at the top and wide at the bottom, the rice noodles after passing through the separation blades 39 maintain a certain spacing, so as to avoid contact between the rice noodles and avoid the situation where the rice noodles are adhered to each other.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
