Background

Rice flour, a special snack in China, is a popular food in southern China, and is a strip-shaped or filiform rice product prepared by using rice as a raw material through the processes of soaking, cooking, layering and the like, rather than a powdery material prepared by grinding the rice as the raw material, which is understood semantically. The rice flour is flexible in texture, elastic, not easy to be burnt in water boiling, not easy to break in dry frying, matched with various dish codes or soup bases to be boiled or fried in dry, smooth and tasty, deeply popular with consumers (particularly consumers in the south), and various types of rice flour can be divided into rice noodles, square rice noodles, corrugated rice noodles, silver thread rice noodles, wet rice noodles, dry rice noodles and the like. Their production processes are largely the same and slightly different, and generally: rice-elutriating-soaking-grinding-steaming powder-tabletting (extruding), re-steaming-cooling-drying-packaging and obtaining the finished product. The traditional rice flour production adopts manual or semi-mechanical production, the production efficiency is low, the requirement of operators is large, and the traditional grinding machine usually only has one hopper to feed into a grinding device for centralized grinding, the coarse taste of rice grains is poor, the process parameters are unstable through manual control, and the increasing quality and quantity requirements of people cannot be met, so that the complete set of rice flour production equipment with high production efficiency and good product quality is necessary.

Chinese invention patent (CN201710981387.7) discloses a large-scale multifunctional complete rice noodle production device. Comprises a rice lifting machine feed opening, a rice lifting machine, a fermentation tank, a rice feeding machine, a rice flour discharge opening, an auxiliary material machine, a continuous material mixing conveyor, a discharge opening, a self-cooked forming machine conveyor belt, a hot water circulation groove, a flour feeding machine, an extruding machine, an aging machine conveyor belt, a fan, an aging machine, a primary silk loosening machine, a flour steaming machine, a discharge groove, a secondary silk loosening machine, a conveyor belt, a feed opening, an inner packing machine, a conveyor belt I, a weighing instrument, a metal detector, a conveyor belt II, a sterilizing machine and a flour picking machine which are sequentially arranged according to the material conveying direction, wherein rice enters the fermentation tank through the lifting machine at the rice lifting machine feed opening, enters the rice feeding machine through the rice lifting machine after being fermented or directly soaked and cleaned, then enters the auxiliary material machine from the rice flour discharge opening to be mixed with the auxiliary material, and then passes through, the noodle feeding machine is connected with the extruder, a hot water circulation groove is arranged around the noodle feeding machine and the extruder to heat materials, rice flour coming out of the extruder is quickly cooled by a fan, the rice flour enters the aging machine through an aging machine conveyor belt and is aged, the rice flour enters the flour steaming machine after being loosened through a primary loosening machine, the rice flour enters a secondary loosening machine through a discharge chute to loosen the rice flour, the rice flour after the secondary loosening enters an inner packing machine through the conveyor belt to be cut and packaged, the packaged rice flour sequentially passes through a weighing instrument through a conveyor belt I, a metal detector, a conveyor belt II, a sterilizer and a flour picking machine, and finally qualified products are obtained.

The invention realizes the production line of the automatic production of the rice flour, improves the production efficiency of the rice flour to a certain extent, but still has great improvement space, for example, the rice flour is intensively milled by using a rice feeding machine for one time, thus the milled rice flour is coarse, the failure of the rice feeding machine caused by card jamming or powder solidification often causes the shutdown maintenance of the whole line, and the invention does not have a steam discharge pipe to cause the overhigh temperature in a workshop and influence the taste of the rice flour and the comfort of operators, thus providing a complete set of equipment which can improve the production efficiency of the rice flour and the taste of the rice flour.
