Twenty five commercial copra kilns in Sri Lanka were studied for variations of their dimentions and copra curing practices in relation to the "Standard Ceylon Copra Kiln" and the quality of copra produced. Changes in the height and the width of the platform resulting in probable changes in drying conditions of copra was noted. The use of powdered charcoal appeared to improve the quality of copra produced and more cost effective than use of coocnut shells. Addition of sulphur dust to the fuel further improved the quality of copra.
