In solvent extraction, flaked soybeans are washed with hot solvent, typically hexane, to separate the solids from the fats. Multiple washes dissolve the oil and carry it away. This oil solvent combination is also known as the miscella. The remaining material is the wet meal and solvent, also known as the marc.

In the modern world, one major source of protein and vegetable oil is from oilseeds, particularly the soybean – an abundant resource which is largely processed using solvent extraction, an efficient and reliable means to separate the high-protein meal solids from the high-energy edible oil.
Membrane processing of soybean oil miscella systems Processing soybean oil miscella systems. The strength of crude miscella obtained after solvent extraction is about 25–30%, which is subjected to evaporation for solvent recycling in the plant (Subramanian et al. 2021).
This work presents a mathematical model for soybean oil extraction in a belt extractor with miscella recirculation. The mathematical model consists of partial …
Finally, the miscella (MISCELLA) enters the final stage of the soybean oil production process, the solvent recovery section.
Soybean Flake Cell Structure. 0.38 mm. Lets zoom in . further to view . ... the faster the miscella diffuses through cell walls, and the faster the miscella in the cells approaches equilibrium with the surrounding miscella. When balancing extraction efficiency . with safety and environmental concerns, ...
Conditions: soybean oil/hexane miscella (25%, w/w), 35 °C, 300 rpm. In the combined process of solvent recovery and deacidification of miscella, it is intended that maximum retention of oil and maximum FFA permeation through the membrane are obtained simultaneously, that is, that the resulted retentate presents the highest percent …
The dense miscella is firstly removed the impurity by hydrocyclone, then enters into automatic slag filter to remove impurity and then enters into the first evaporation system. Solvent extractor is the extraction equipment designed by CHEMSTA for the soybean white flake(low temperature soybean meal) and is our patented product.

Miscella refining This method was originally developed for neutralizing cottonseed oil. It enables most of the gossypol to be removed with simultaneously low neutralization losses ( Fig. 6 ).
From these values it is clear that the miscella permeability decrease when the feed oil concentration increases. A higher miscella concentration in the feed implies an augment in the quantity of dissolved solutes, increasing the prompt fouling (primary adsorption) and concentration polarization effects, decreasing the membrane permeability.
