Abstract:

Several wet protein concentrate recovery systems were evaluated using alfalfa and other plant materials. These systems included floatation, belt filtration, a combination floatation/belt filtration system, and centrifugation. The latter was totally ineffectual with the unit used. Belt filtration provided moderate levels of solids in the recovered product because an auxliary vacuum dewatering device can be incorporated, but it a has poor recovery rates. Floatation provided good recovery but a dilute protein product resulted. Use of the floatation as a pretreatment to belt filtration provided enhanced recovery rates and moderate solids concentration. Alfalfa and other plant materials (birds foot trefoil, oats, bluegrass, sweet corn stalk residue and potato vines) showed similar trends in response to the various separation systems and did exhibit considerable variations of recovery characteristics.
