LOW-TEMPERATURE AND COMBINATION CORN DRYING IN ONTARIO.

THE PERFORMANCE OF A LOW-TEMPERATURE CORN-DRYING SYSTEM WASSTUDIED IN 1978 AND 1979. LOW-TEMPERATURE DRYING TRETMENTS INVOLVED AMBIENT AIR DRYING OF CORN DIRECTLY FROM THE FIELD,AND DRYING OF PARTIALLY DRIED CORN IN A COMBINATION HIGH-LOW TEMPERATURE APPROACH. ONE OF THE TWO LOW-TEMPERATURE BINS USED IN EACH YEAR HAD A BIN-WALL SOLAR COLLECTOR FOR SUPPLEMENTAL HEATING. THE SPECIFIC ENERGY CONSUMPTION FOR ALL FOUR EXPERIMENTS WAS FOUND TO VARY BETWEEN 3. 9 AND 4. 1 MJ/KG OFWATER REMOVED, WHICH IS SIMILAR TO THE ENERGY USE IN A CONVENTIONAL HIGH-TEMPERATURE, CONTINUOUS-FLOW DRYER. THE CORN QUALITY IN THE COMBINATION DRYING EXPERIMENT IS SUPERIOR TO THAT OF CONVENTIONALLY DRIED CORN.
