Impurity Removal Standards for Maize Processing Equipment

In the production of maize processing equipment, effective removal of impurities is a crucial process for enhancing finished product quality, reducing ash content, and ensuring production safety. What, then, are the specific impurity removal standards for maize processing equipment?

To guarantee the purity of maize entering the mill, all types of impurities in the raw material must be removed. The primary focus should be on various dust and debris impurities, particularly inorganic impurities that significantly impact production and product purity. When sequencing impurity removal, priority should be given to eliminating large dust particles and debris that pose direct hazards to production, followed by other mixed and adherent impurities.

For impurities differing from corn in two or more aspects, simpler and more effective removal methods should be prioritised. For instance, screening proves more effective than stone removal machines for sand and gravel particles significantly larger or smaller than corn kernels.

　　Impurities with a suspension velocity similar to corn kernels present a significant challenge for removal, such as larger mud clods. Corn processing equipment requires selective sorting or a combination of multiple methods to eliminate such impurities.

　　Within corn processing operations, hard, large impurities can damage machinery, particularly high-impact equipment, while sparks from collisions may trigger dust explosions. Flexible contaminants like string, paper scraps, and similar materials readily cause entanglement and blockages. Dust from raw materials can escape, causing contamination and compromising the production environment. To safeguard normal production and extend the service life of corn processing equipment, these impurities must be removed as thoroughly as possible.
