00:00Inventor Norbert Rilu Black History. As a result of his invention of the multiple-effect evaporator
00:05under vacuum, Norbert Rilu, 1806-1894, revolutionized sugar processing by revolutionizing the process
00:13by which it was processed. He was the first to recognize that at a reduced pressure, the
00:20repeated application of latent heat would result in the production of higher quality sugar at a
00:25lower cost and this was Rilu, greatest scientific accomplishment.
