Title: shiping container kiln Dryer Design

Hello everyone,

Conserning the shiping container kiln why does the traditional loading design allows only 5Kbf for a 40ft container (Nyle, global container kiln). Is there anyone a problem with the design I propose (Two sets of vent)?

Note: The kiln is dedicated to harwood lumber for furniture market. No need of long planks (maximum lenth 7.5in), but about 10 000bf capacity.

Standard: Longitudinal vent

Proposed: Two sets of transversal vent

The main problem I can see with that design is how wide it makes the stacks of timber. You might get a significant moisture gradient or reduced airflow as the air has to pass through such a wide stack.?
Also is the actual dh unit going to be up to drying the extra amount of wood?

Not saying it wont work, but thats just the possible problems I can see

Cheers

Ian

It could be made to work but you would be limited to boards that are less than 8' long. It would not have practical value for most people. There have been kilns built this way but you need a pretty good sized plenum at each and and one in the center at least twice as large. If you have single phase power, have the fans blow toward the two ends, not at each other.
