The cleaned cocoa beans are tipped on to a vibrating belt heated by infra-red strips to obtain what is called the ‘pop effect’: i.e. the 6-8% moisture in the beans is reduced to 4-6% by the heat and the shells become more brittle, making the separation of nib - the inner seed of the bean after the shell has been removed - and shell easier during shelling.
