Summary Advantages of the Rotocel system for cottonseed cake extraction may be summarized in the following manner: Economical conversion to solvent extraction is possible by utilizing existing or reconditioned screw‐press equipment. Conditioner and flaking rolls are not required for this process. The electrical power requirements for the cake preparation and extraction are less than the power reduction when converting from straight pressing to a prepress operation. This results in a net savings in power consumption. Vapor scrubbers used in conventional plants are not required in this process. Efficient extraction at low solvent ratios keeps the steam requirement of this process to a minimum. Low residual oil in extracted meal accomplished by this process yields a maximum product value per ton of seed. The low temperature vapor desolventizer eliminates discolorization and protein degradation of the cake granules during the desolventizing step.
