EFFECT OF SCOURER SCREEN PATTERNS ON THE WHEAT HUSK REMOVAL EFFICIENCY

Abstract

The scourer machines remove wheat husk contaminated with pesticides and other impurities that adversely affect product quality and shelf life. For this purpose, at least one scourer machine is used in each industrial grain flour factory, depending on the capacity. The efficiency of these machines is highly dependent on the surface texture and scourer screen patterns. In this study, the efficiency of the wheat scourer machines with various wall patterns and meshes was investigated experimentally. The investigation employed six distinct types of scourer screens. Type-4 has produced the best results in fractured grain rate, whereas Type-2 has produced the best in ash content. It was revealed that wheat's scouring efficiency and physical and chemical properties vary depending on the scourer screen pattern.
