The invention discloses a corn flour production and processing mechanism based on multidirectional feeding. The corn flour production and processing mechanism comprises a corn grain crushing device, apowder mixing device and a powder transfer device according to the technological process from front to back. The corn grain crushing device comprises a crushing unit, a drying unit and a material return device according to the technological process in sequence. The powder mixing device comprises a material mixing tank and a material mixing upper cover covering the material mixing tank, and a cavity of the material mixing tank is internally provided with a first material mixing and screening plate, a first mixing chamber, a second material mixing and screening plate and a crushing/mixing integrated chamber from top to bottom in sequence. The powder transfer device comprises a transfer conveyor belt, a turnover discharging device, a transfer baffle, a conveyer bucket, a transfer elastic device and a transfer lifting base station from front to back in sequence. The corn flour production and processing mechanism has the advantages of quality guarantee of produced corn flour, good mixing effect of corn flour and flour, high continuity of operation, precise single feeding quantity and high working efficiency, and is not liable to caking or blockage.
