A description of the inventions design is given in Rillieuxs 1846 patent: A series of vacuum pans, or partial vacuum pans, have been so combined together as to make use of the vapor of the evaporation of the juice in the first, to heat the. Throughout most of the eighteenth century indigo, a blue dye, was Louisianas cash crop, but the ravages of disease and insects forced planters to look for alternatives. The vacuum pan was enclosed in an area with the air removed (this was necessary because liquids can boil at a lower temperature in the absence of air than with air present, thus costing less). Originally animal power was used to grind the cane; by the 1830s, steam power began to replace animal power. Copyright 2005. Each successive chamber used the latent heat released by steam from the preceding chamber.
