Solvex™️ Expander

Product description

The Anderson Solvex™️ packs material to be extracted into a dense, yet very porous structure. This allows the solvent easier access to the oil, resulting in up to 50% increases in extractor capacity, 40% reduction in solvent hold-up in the solid product (marc), 20% reduction in solvent in the liquid product (miscella), and an overall reduction in solvent losses.

Expanders, like the Solvex™️, lower overall plant energy consumption and loading on the extractor, hence reducing their operational costs and increasing their capacity. The Solvex™️ Expander can also reform dense pre-press cake into a porous collet for improved extractor efficiency on high oil content materials, providing similar benefits as with soybeans.

The Solvex™️ uses steam as its primary heat source. Using steam-generated heat, the screw propelling the material through the expander requires less horsepower per ton, allowing operators to process more material in a given timeframe.
