In a method and apparatus for continuous-flow treatment of flowable unpumpable particulate material with a treating fluid at other than ambient temperature and/or at other than atmospheric pressure, a downward flow of a column of the material under the effects of increasing weight and the action of a downward conveyor creates an increase of pressure within the material flow for injection of the treating fluid, and subsequently an upward flow of the material creates, under the effects of decreasing weight and an upward conveyor creates a reduction of the pressure, e.g. at or about atmospheric, whereby need for mechanical airlocks at the entry and exit of a pressurised treating chamber is eliminated. <IMAGE> |
