[0072] working methods

[0073] This technical solution provides a fine grinding device for rice processing, mainly addressing the processing of small batches of freshly ground rice flour. The device is powered by mains electricity via a control unit. Rice enters the grinding chamber from the rice hopper 13. The upper cutter disc 31 is threadedly locked to the upper part of the grinding machine frame 4. The lower cutter disc 32 is driven to rotate by a cutter disc drive motor 62. The upper and lower cutter discs 31 and 32 together form the grinding chamber. The upper cutter disc 31 is driven to rotate and lift by an upper cutter disc adjustment motor 71. This lifting action increases the distance between the grinding chamber outlets at the edges of the upper and lower cutter discs 31 and 32. The smaller the distance between the grinding chamber outlets, the smaller the rice flour particles produced, thus obtaining rice flour of varying fineness. When not grinding, rice can still be stored in the rice hopper 13. When storing rice, a lid can be fitted to prevent the rice from getting damp.

[0074] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors.
