Another alternative approach for the conching process is the use of ball mills in which the refining stage is applied simultaneously. However, the use of ball mills has the disadvantage of high fat content requirement. Also, water and undesirable volatile compounds cannot be properly removed in the ball mill systems (Bolenz et al., 2014).
