The grain cleaner machine in a lentil mill is a precision instrument designed to enhance the quality of lentils by removing impurities and foreign materials. It begins with a feeding system that ensures a steady flow of lentils, followed by a pre-cleaning section to eliminate larger debris. The machine employs vibrating screens and sieves to sort lentils by size, while an aspiration system and gravity separator further refine the cleaning process. A magnetic separator removes metallic impurities, and a dust collection system maintains a clean environment. Constructed with durability in mind, the machine is easily adjustable for various lentil varieties and features a user-friendly design for efficient maintenance, contributing to the production of high-quality, contaminant-free lentils.
