Hi all, If you really want to dry something cheap use a greenhouse. See<br>

I thought about doing this as part of my research using a solar kiln. At it's simplest this might be wheel in an open mesh side container full of moist chip, leave for a few days, take out nice dry chip and combust/gasify. The problem, of course, is that the chip will only dry towards the outside of the container. Handling costs get restrictive if you put the chip in trays and placing the chip in some kind of tumbler involves extra expense for the tumbler and also some energy (and cost) to drive the tumbler.<br>
<br>
I was in Finland a few weeks ago where I was introduced to the concept of a drying trailer where air is actively moved across a relatively small container full of chip. Apparently this can dry the chip reasonably efficiently. I might revisit the solar kiln idea using this approach. As with everything in this area for a commercial operation it's all about the cost<br>
