FIELD: process engineering.
SUBSTANCE: invention relates to fluid extract expressing from pressed material. Pressed material is transferred by screw press along pressing path, subjected to pressing pressure and mixed with at least one extragent. The latter is withdrawn together with extract from pressed material. Extragent is added to pressed material with weight fraction making twice as much as that of extract contained in pressed material. Proposed device comprises screw press with screw moving in cylindrical shell. Said press is coupled with at least one extragent feed device and at least one extract collecting device. Said feeding device is communicated with proportioner that outputs required amount of extragent.
EFFECT: higher efficiency.
