Title: David C Drown: Innovator in Oil Recovery and Alcohol Ester Purification
Introduction
David C Drown is an accomplished inventor based in Moscow, ID (US). He holds 2 patents that showcase his innovative contributions to the fields of oil recovery and alternative fuel sources. His work reflects a commitment to enhancing processes that can lead to more sustainable practices.
Latest Patents
One of Drown's latest patents is a "Process to recover oil from crumbs, food particles and carbohydrate." This invention provides a process and apparatus for the separation of oil or fat from food particles, carbohydrate matrices, and crumbs in a continuous process. The apparatus allows for the reuse and recycling of the separated oil or fat. The process involves mixing crumbs with hot water and agitating the mixture for a predetermined time. After agitation, the mixture is introduced into a non-turbulent container where the oil/fat, water, and crumbs stratify. This results in high-quality oil/fat separating and rising based on its buoyancy, allowing for easy removal and reuse. The water and crumbs also separate and can be removed similarly.
Another significant patent is the "Method for purifying alcohol esters." In this invention, triglycerides, such as vegetable oils and animal fats, are esterified with alcohols to produce alcohol esters that can serve as alternative fuel sources. By-products of the transesterification reaction are stripped from the effluent using a recovery alcohol, which can be an isolated by-product of the reaction.
