Description

Technical Field

[0001] This utility model relates to the technical field of corn grits processing, and in particular to a cylindrical screen for removing impurities from corn grits. Background Technology

[0002] Cornmeal, also known as corn grits or corn crumbs, is a common type of coarse grain. It is made from corn through peeling, crushing, grading, and screening. It is often used to cook porridge or cooked with rice. During the processing of corn grits, a small amount of ultrafine corn flour (commonly known as "flying flour") is produced after the corn is crushed and adheres to the corn grits particles. This ultrafine corn flour not only affects the luster of the corn grits, but also forms a paste during the cooking process, increasing the viscosity of the porridge or rice and affecting its taste. A corn grits brushing machine, as disclosed in prior art publication CN208742996U, includes a housing. A horizontal plate is hinged to the lower left side of the inner wall of the housing. Mounting blocks are respectively provided on both sides of the upper end of the horizontal plate. A first sieve barrel is rotatably connected inside the mounting groove. Brushes are symmetrically arranged in the middle of the inner wall of the first sieve barrel. A second sieve barrel is connected to the outer side of the rotating shaft via a connecting rod. The second sieve barrel is located inside the first sieve barrel. A motor is mounted on the upper end of the motor base. The output shaft of the motor is fixedly connected to the left end of the rotating shaft. A second outlet is opened in the middle of the right side of the outer wall of the housing. A first outlet is opened at the bottom end of the housing, and the first outlet is located directly below the through hole. However, during separation, the corn grits are easily scattered and wasted, which also affects the working environment and results in poor work continuity. Utility Model Content
