What does a Liquor Grinding Mill Operator do?
Tends one or more grinding mills that grind nibs or preground nibs of cocoa bean paste to obtain liquid chocolate of specified consistency: Starts machine and opens slide gate of hopper to release nibs, or turns valve to permit paste to flow through grinding stones. Observes ammeter on machine to determine amount of current produced by friction of grinding stone, and moves handles to adjust clearance between stones. Feels and tastes liquor to ascertain if texture conforms to standards. Draws sample for laboratory analysis. Pumps liquor to storage tanks. May pregrind nibs into paste-like consistency.
