Summary
A preliminary cost study was made of a combination screw-press extraction-fractionation plant. The economic advantage of the combination plant over the screw-press operation as shown here is small in comparison with the large additional investment required for the combination plant. The present value of the combination process lies in the production of two new products, a purified high-protein meal and a concentrated pigment gland fraction and in the possibility of producing a high-grade oil as the removal of the whole pigment gland prevents the pigment material from coming in contact with the oil. Pilot-plant work under way indicates improvements in the process such as a higher recovery of the meal as purified meal. The development of additional and more profitable uses for the products would increase their value and provide a broader and more stable market for cottonseed.
