Title: If you had a smaller volume dry kiln would your drying quality improve?
Post by: PhilM on July 24, 2014, 11:03:47 AM

Do you think that if you had a smaller volume dry kiln your drying quality would improve?  Possible reasons for improved drying quality could include:

• less time required to build a complete kiln load of same species, thickness, and length (and less need to mix species, thicknesses, or initial moisture contents)
• less time would mean less chance of developing the precursors of stain in lumber before the kiln during summer months
• less time might mean lumber packages spend a similar amount of time on air drying yard, hence have similar initial moisture contents so that the starting kiln schedule is right for all the lumber
• a smaller kiln should be able to achieve more uniform drying conditions in terms of heat, humidity and air flow, resulting in a more uniform final moisture content

Obviously having multiple smaller kilns (as opposed to a single larger kiln) would be a larger capital investment.  Do you think there is enough demand for lumber having a high drying quality that would support the increased price due to increased costs?

Yes, possibly.  Having smaller kilns could help the operator control the species or dimension mix better and also help to keep the inventory rotated.
