ABSTRACT:
An apparatus for treating solids with a liquid at elevated or ambient temperatures comprises an assembly of vertical Pot (1) sealed by Lid (3) in which Pot (1) contains the liquid and horizontal low level stirring means (6) inducing a liquid vortex and contains disposed above stirring means (6) horizontal spokes (9) offering minimum interference with the vortex and contains vertical open cylinder (11) bottomed by central apertured layer (10), being liquid permeable but supporting solids impermeably. The vortex rises through spokes (9) up internal vertical wall of Pot (1) and into diagonally opposite inlets (18) of horizontal tube (16) suspended internally from lid (3) above cylinder (11). Liquid downpours through exit (19) of tube (16) through solids in cylinder (11) and through layer (10) to re-enter the vortex. Layer (10) is predisposed above the unstirred level of the thermostated liquid, hence at the cease of stirring, the total liquid fall back leaves the solids isolated from the liquid at the thermostated temperature of the assembly.
