Dry Bean Processing Plants

Dry bean processing requires a cleaning and grading sequence that removes foreign material, splits, and off-colour beans to produce a clean, graded, and visually uniform product for the retail and export market. Facet Engineering designs dry bean processing plants including intake and pre-cleaning, destoning to remove stones and dense contaminants, aspiration to remove dust and light material, screening to grade by size, gravity table separation to remove shrivelled or low-density beans, and electronic colour sorting to remove discoloured or damaged beans. The sequence and combination of machines is determined by the incoming bean quality and the required output specification. The plant concludes with weighing and bagging at the required bag size.
