Work flow of corn processing impurity removal device

The corn processing impurity removal device includes a vibrating screen, a fan and a connecting pipe, and is characterized by:

1. There are two sets of vibrating screens installed vertically in series on the upper and lower floors in a closed system. The upper end of the closed system is connected with gas and a fan. The aperture of the upper vibrating screen is larger than the diameter of corn grains, and the aperture of the lower vibrating screen is smaller than that of corn grains. path.

The aperture diameter of the upper vibrating screen is 8-12 mm, and the aperture diameter of the lower vibrating screen is 4-6 mm.

The impurity removal device has a discharge port on the upper vibrating screen, a discharge port on the lower vibrating screen, and a discharge port three on the bottom of the closed system.

2. The corn processing impurity removal device is composed of a closed system consisting of a vibrating screen, a fan and connecting pipes;

3. The closed system allows the air flow generated by the fan to pass through in one direction and be discharged by the gas, especially the upper and lower vibrating screens connected vertically in series. The air flow first passes through the lower vibrating screen from bottom to top, and then passes through the upper vibrating screen from bottom to top. vibrating screen;

4. The aperture of the upper vibrating screen is larger than the aperture of the lower vibrating screen. After the impurity-removed corn enters the upper vibrating screen from the upper part of the closed system, due to the upward airflow, the lighter impurities, such as corn silk, are first blown out by the airflow;

5. After the corn enters the upper vibrating screen, as the vibrating screen vibrates, since the hole diameter of the upper vibrating screen is slightly larger than the corn particle size, the corn enters the lower vibrating screen through the upper vibrating screen holes, and the impurities with larger diameters remain on the upper vibrating screen and follow them. With vibration, it gradually flows to the discharge port and is discharged;

6. The corn entering the lower vibrating screen is under the vibration of the lower vibrating screen. Impurities with smaller particle sizes enter the bottom layer through the sieve holes and are discharged. The aperture of the lower vibrating screen is smaller than the usual corn particle size. The corn kernels after removing impurities are vibrating Then it is discharged through the second discharge port.
