TCF Sales offers two mill grinders for grinding cacao nibs into chocolate. Produced by European manufacturer FBM, the Pre-Grinder and Rumbo Mill Grinder are effective machines for reducing particle size. The Pre-Grinder is used to quickly grind nibs into a paste. Nibs are poured into the top of the machine and pushed out in a matter of minutes in the form of a chocolate liquor. This brownie-like paste is then moved to your Mill Grinder for further processing.
