In the movie Willy Wonka and the Chocolate Factory, golden chocolate eggs are placed on an eggdicator scale to determine if they’re good or bad. Good eggs are shipped out. Bad eggs go down the garbage chute into the incinerator. Even spoilt child Veruca Salt is sent down the garbage chute. When it comes to separating good green or roasted beans from bad, the same theory applies using Satake’s range of optical sorters. Sid Jain, Satake Australia’s Optical Sorting Sales Engineer, says having a clean bean is the difference between a good flavour in the cup and an excellent one.
