Norbert Rillieux (1806-1894) revolutionized sugar processing with the invention of the Multiple Effect Evaporator under Vacuum. Rillieux's great scientific achievement was his recognition that at reduced pressure the repeated use of latent heat would result in the production of better quality sugar at lower cost.

What effect did Norbert Rillieux have on Louisiana agriculture? He invented a vacuum pan evaporator to refine sugar into a finer, whiter product with less costs. What was the major means of transportation in antebellum Louisiana?

Norbert Rillieux (1806-1894) sent this scale model of the Multiple Effect Vacuum Evaporator to the US Patent Office when he applied for, and received, his first patent in 1843. Reillieux's invention would revolutionize the sugar industry.

Rillieux used steam instead of wood fire to heat and power his machine. The hot steam was passed through closed tubes throughout the apparatus to provide constant heat during the entire process. He was also able to trap any heat escaping the machine, and diverted it to other areas.

Norbert Rillieux revolutionized the sugar industry by inventing a refining process, evaporation in multiple effect, that is still in use today not only for the production of sugar, but also of soap, gelatin, condensed milk, and glue, as well as for the recovery of waste liquids in factories and distilleries.
