A melanger used to make chocolate

A melanger (or melangeur, from French: mélangeur, lit. "blender") is a stone-grinder that is used in chocolate-making. It typically consists of two granite wheels, which rotate inside a metal drum on top of a granite base. Given enough time the wheels can reduce the particles to sizes measured in microns, therefore making a smooth chocolate paste from cocoa beans.

Stone grinding tools have been widely used in history to make food. In Mesoamerica, cocoa was ground using a metate. Industrialization in the late 18th century favored the use of larger and water powered machines. The first melanger prototype was invented in 1811 by a French engineer named Poincelet. It was soon adopted all over Europe.[1] In 1819, François Pelletier powered a grinder and a melanger with a steam engine. This allowed him to produce 76 kilos of chocolate in twelve hours, a quantity which typically required 7 workers at the time.[2] In 1826, the melanger was also adopted (and perhaps further developed) by Philippe Suchard in his chocolate factory in Neuchâtel.[3][4]

Nowadays melangers tend to be used by small chocolate manufacturers only.[5] Melangers can be both used as refiners and conches.[6]

Tabletop wet grinders are smaller versions of the melanger.
