Title: The Innovations of Francis E. Luddy
Introduction
Francis E. Luddy is a notable inventor based in Hatboro, Pennsylvania, with a remarkable portfolio of eight patents. His work primarily focuses on the fractionation of fats and oils, utilizing innovative processes that enhance the production of specialty fats for various applications.
Latest Patents
Luddy's latest patents include a process for obtaining a fat fraction with azeotropic solvents. This process involves dissolving fats or oils in a binary azeotropic solvent mixture, which is then cooled to crystallize a high melting stearine fraction. The high melting stearine fraction is subsequently removed from the solvent-crystal mixture. If the goal is to produce both a high melting fat and a lower melting fat (oil), the process concludes at this stage. However, for those seeking an intermediate melting solid fraction, a smaller portion of the high melting stearine fraction is removed before cooling the remaining solution to a lower temperature. This results in the crystallization of an intermediate melting solid fraction, which shares physical properties similar to cocoa butter. The remaining filtrate solution yields an oil, and the entire fractionation process can be executed in either batch or continuous modes.
