MUEZ-HEST Solvent Extraction Plant is the most modern way of recovery of oil from oil bearing materials at very low temperature under vacuum to produce excellent quality of oil, compared to mechanical pressing which works under high temperatures and high pressure and causes oxidation of oil. Recent developments of the Expander system with the squeezomatic attachment invariably ensures even direct extraction of high oil content material like sunflower, rapeseed, Rice Bran, Soyabean producing the best quality of crude oil and completely eliminates the pre-pressing operations of old technology expellers. Thanks to this most modern and versatile design of expanders which can be very well adopted in the preparatory section itself. MUEZ-HEST continuous solvent extraction plant thus completely eliminates the dependency on Oil Mill Plants during lean seasons and gives additional advantage to solvent extraction plant owners by direct extraction from high oil content seeds.
