Abstract

A counter-current-cum-concurrent extractor (1/20) comprises a substantially “V”-shaped body (2) having a pair of inclined tubular arms (3 and 4) interconnected at the bottom (5), the said arms forming a concurrent cylinder (C1) and a counter- current cylinder (C2), an inlet (7) for feeding the raw material (8) provided at/near the top end of the concurrent cylinder, an inlet (10) for feeding the solvent (11) and an outlet (15) for discharging the waste (16) of extracted raw material provided at/near the top end of the counter-current cylinder, an opening (22) for sucking out the extract provided near the bottom of the counter-current cylinder, an inlet (12) for feeding the particularly saturated extract (13), received from the counter-current cylinder (C2), provided near top end of the concurrent cylinder (C1), an outlet (19) for recovering the final concentrated extract (18) provided at the bottom of the extractor below the junction (5) of the said two inclined arms and means (P1, P2/S1, S2) for gradually moving the raw material from top to bottom of the concurrent cylinder and then from bottom to top of the counter-current cylinder and the said means being provided with perforations (17/21), such that the solvent and/or the extract passes downwards therethrough without allowing any raw material particles to pass through.
