Description

Technical Field

[0001] The utility model relates to the technical field of rice noodle processing, in particular to a filter with a quickly replaceable filter screen. Background Art

[0002] Vermicelli is a thin, transparent rice product. During the production process, the rice paste needs to be spread on a hot pan to form a thin layer of skin, which is then removed from the pan. Vermicelli has a chewy texture and is often used to make cold dishes, stir-fried dishes, etc.

[0003] Vermicelli is a long, translucent rice product. During the production process, the rice paste needs to be squeezed out through a mold to form the shape of vermicelli. Vermicelli has a smooth taste and is often used in making soups, stir-fried dishes, hot pot, etc.

[0004] The processing of vermicelli and rice noodles mainly includes the following steps:

[0005] Raw material selection: Choose high-quality rice, corn, mung beans, sweet potatoes, etc. as raw materials;

[0006] Cleaning: Soak the raw materials in clean water to allow them to fully absorb water, then rinse with clean water;

[0007] Grinding: Put the cleaned raw materials into the grinder, add appropriate amount of water, and grind into rice paste;

[0008] Clarification: Pour the ground rice slurry into a cloth bag and squeeze it to drain the water out of the rice slurry to obtain rice paste;

[0009] Steaming: Pour the rice paste into a steamer, steam it over high heat, take it out and let it cool;

[0010] Extrusion molding: Put the steamed rice paste into the vermicelli machine, and use the machine to squeeze the rice paste through the mold to form the shape of vermicelli;

[0011] Cooling: Put the extruded vermicelli into clean water to cool and shape it;

[0012] Drying: Take out the cooled vermicelli and dry them in the sun or in a dryer;

[0013] Packaging: Pack the dried vermicelli for easy storage and transportation;

[0014] Testing: Conduct quality testing on finished vermicelli to ensure they meet food safety standards.

[0015] At present, in the processing of rice noodle noodles, the rice slurry needs to be filtered for moisture in the clarification step, and at this time, it needs to be operated in coordination with a filter screen. However, due to the certain viscosity of the rice slurry, if only gravity filtration is adopted, the processing operation cannot be carried out. The traditional method uses a cloth bag for operation, but the cloth bag is soft and easy to break, and cannot be cooperated with a machine for pressurized filtration. Therefore, a filter needs to be designed to facilitate the filtration of the rice slurry moisture. Utility Model Content
