Most dryers are relatively simple usually a  box often 3 to 4 feet wide and 
6 to 8 feet long.
and abour 4 feet high. These are usually covered with a single sheet of tin 
and generally have
a substancial shelf built across abour 3/4 of the way up put the copra on 
for drying. there is stron box built around the top
to hold the cocnuts in place. When initially loaded with cracked coconuts 
this is  heavy load. After firing several time with a smoldering fire
husk in a pit underneath. Tthere are a great many variations in style 
quality and opperation. I have seen neatly made units
fired only by charcoal from burned down coconut shell to ones so rickity 
they collapse an but the whole load of copra.
There has been much experiemtation elswhere India Sri Lanka in particular 
but little adoption of anything else here
Obviously double walls insulation and better fire control are early step. I 
suspect that perhaps Paul Oliver peopl in the Phillapines
will have lots of information as well.
