1. METHOD OF CHANGING THE TEMPERATURE OF GRANULAR MATERIAL WHICH COMPRISES THE STEPS OF: (A) FEEDING SAID GRANULAR MATERIAL ONTO THE FEED ZONE OF A CONVEYOR TABLE WHICH INCLUDES AN ELONGATED TEMFROM SAID FEED ZONE, BOTH SAID ZONES HAVING A MULTITUDE OF LONGITUDINALLY SPACED PASSAGES EXTENDING THERE-THROUGH AND INCLINED TO THE TABLE IN A COMMON DOWNSTREAM DIRECTION; (B) IMPARTING TO SAID MATERIAL ON SAID FEED ZONE A HORIZONTAL MOMENTUM TOWARD SAID CONDITIONING ZONE BY FLOWING GASEOUS ACCELERATION JETS THROUGH THE SAID PASSAGES IN THE FEED ZONE OF SAID TABLE WITH STRONG DOWNSTREAM COMPONENTS, SAID JETS HAVING TEMPERATURES MATERIALLY DIFFERENT FROM THE TEMPERATURE OF SAID MATERIAL, THEREBY MOVING SAID MATERIAL ONTO SAID CONDITIONING ZONE;
