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.

Norbert Rillieux (March 17, 1806 – October 8, 1894) was a Louisiana Creole inventor who was widely considered one of the earliest chemical engineers and noted for his pioneering invention of the multiple-effect evaporator. This invention was an …

2021年10月27日 · Rillieux’s invention, the multiple-effect evaporator, streamlined what had been a slow and costly process for purifying cane juice by using a series of vacuum chambers that used heat more efficiently and reduced waste.

Rillieux was educated in France and developed the multiple-effect evaporator in 1834. The system he invented utilized a closed chamber for evaporation, whereas the “Jamaica train” evaporated into the open air.

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 …

The multiple-effect evaporator was invented by the American (Louisiana Creole) engineer Norbert Rillieux. Although he may have designed the apparatus during the 1820s and constructed a prototype in 1834, he did not build the first industrially practical evaporator until 1845.

Norbert Rillieux (1806-1894) was the inventor of the multiple-effect vacuum evaporator, which revolutionized the processing of sugar. He gained recognition as one of the prime architects of the modern sugar industry.

Norbert Rillieux's Multiple Effect Evaporators. The following is an excerpt from Oliver Lyle's Efficient Use of Steam. Figures 1 and 2 shows the original Rillieux triple effect evaporator which was installed in a Louisiana sugar factory in 1843. The first effect normally took exhaust steam from the engines driving the cane mill.

Rillieux's multiple-effect evaporator harnessed the principles of latent heat and vacuum to enhance efficiency. The system comprised a series of containers, or effects, where sugarcane juice was subjected to sequential stages of evaporation.

Rillieux navigated a fine line between enslaved persons of color and free whites. He was educated in France and returned to Louisiana to practice engineering. There he invented the multiple- effect evaporator, a safer and more efficient device that improved the consistency of sugar produced on plantations. Rillieux is celebrated today as
