Mathematical modeling of non-Newtonian fluid flow in an extruder channel, extraction included

Koshevoy E.P., Meretukov Z.A.

Phosphatide concentrate (vegetable lecithin) processing consists in direct extraction of vegetable phospholipids produced by sun flower seeds processing. When extrusion agglomeration was developed to remove solvent from phosphatide concentrate saturated with acetone after extraction refining, the flow of non- Newtonian fluid in extruder channels was modeled, high grade acetone (GOST 2768- 84) being used as a solvent. The paper presents analytical solution of differential equations that describe the axial flow of non-Newtonian fluid in the channel of single screw extruder combined with extractor.
