Solar Dried Lumber Moisture Concerns

A solar kiln will dry the wood with a smaller chance of defects than air drying "And they won't dry wood too fast " says Dr Eugene Wengert an extension forest products specialist at the University of Wisconsin-Madison "It's pretty much a 'set it and forget it' system You can just put the wood in there and almost forget it

Drying kinetics and mathematical modeling of hot air

Drying kinetics of coir pith was studied and the properties of compressed coir pith discs were analyzed Coir pith particles were oven dried in the range of temperatures from 100 to 240 C and the rehydration ability of compressed coir pith was evaluated by finding the volume expansion The optimum drying temperature was found to be 140 C Hot air drying was carried out to
