Successful operation of the apparatus, as described in this paper, was conducted at rates of feed that ranged from 1.89 to 5.51 Ibs. per hour. The data show that cottonseed oil soapstock can be heat-treated continuously on a pilot-plant scale so that both the free and total gossypol content, as measured by thep-anisidine method (2,3), are reduced to values as low as 0.003%. In the work reported, the heat transfer medium was oil, heated electrically. Commercially a direct, gas-fired, heat exchanger would be more practical. These experiments indicate that additional work on a larger or plant scale is justified, provided, of course, that the marketing economics involved are favorable. |
