Summary Improvements and refinements in the process for filtration‐extraction of cottonseed resulting from further pilot‐plant development studies are described as well as their adaptation to the first commercial plant. These improvements which depict the present status of the process for cottonseed include principally certain modifications in the method of conditioning of the meats or flakes prior to cooking and in the procedure for crisping; selection of best conveyor type for conveying cooked material over relatively long distances without objectionable comminution; selection of filter medium combining the desired properties of durability, non‐fouling, and low fines retention; determination of optimum filter‐cake thickness; and development of a method for clarification of the product miscella by continuous recycling through the formed cake on the filter. Also discussed is the quality and color stability of the oil produced from comparable lots of cottonseed by the filtration‐extraction process, as compared with that by hydraulic pressing, and by solvent extraction of uncooked flakes.
