A bench‐scale method for evaluating the processing characteristics of oilseeds for filtration‐extraction

Abstract

Summary A simple laboratory testing apparatus and its use have been described. With relatively few pounds of material it is possible to evaluate many preparation and filtration variables and to predict with a fair degree of accuracy the behavior of a continuous horizontal vacuum filter. It is felt that such a unit will be invaluable for use in commercial plants, especially during the start‐up operations of a new plant. The bench‐scale unit should also find application in connection with other processes employing the unit operations of extraction and filtration.

Crambe processing: Glucosinolate removal by water washing on a continuous filter

“…Filtration rates were determined on a bench-scale test unit similar to that described by Graci et al (21); it consisted of a stainless steel filter funnel, a 4000-ml vacuum flask, a Cartesian manostat for vacuum control, and a mercury manometer (Fig. 2).…”

STAFF-INDUSTRY COLLABORATIVE REPORT Filtration-Extraction of Cottonseed Oil

“…The filtration-extraction plant of the Mississippi Cottonseed Products Co., located at Greenwood, Miss., has been essentially in continuous operation on cottonseed and soybeans since January 26,1954. It processes from 14Ó to 200 tons of cottonseed per day (or 80 to 130 tons of soybeans).…”

“…Bench-scale tests (26) and pilot-plant data have been correlated with fullscale commercial operations. Now data can be translated reliably from one scale to another; researchers can test new materials with bench-scale operations only, to determine commercial feasibility.…”
