Methods for inhibiting the deposition of proteinaceous materials on heat transfer surfaces.

摘要

Methods for controlling the formation of proteinaceous fouling deposits in high temperature evaporators and concentrators as employed e.g. in processing steepwater in the wet milling of corn. The methods comprise adding lecithin, or a long chain fatty acid to the steepwater in effective inhibiting amounts, e.g. an amount ranging from about 150 parts per million to about 500 parts per million steepwater.
