SORTEX Z+ first to sort coffee by colour and shape
Wednesday 25 July 2007Bühler launched new shape sorting technology that allows coffee processors to sort simultaneously by shape as well as colour, at the Tea and Coffee World Cup in Geneva.
It gives Bühler’s SORTEX Z+ optical sorters a unique advantage as the company targets this important market sector. Until now it was only possible to distinguish defects in coffee beans by optical colour sorting. The removal of foreign material the same colour as the accept product, such as brown sticks in roasted coffee, could previously only be done by a mechanical or hand sorting process.
