Good question @frankmeiring1049. We asked the Pac Veneer team -- here's their response: "Due to fact that we run mostly hemlock we don’t run into resin/sap issues in our process." They said when they use Doug-fir trees, there is some residual pitch in the peeling and drying processes.
@@rayonierinc.4618 Thank you for the swift response! I'd love to ask a follow-up question(s): Does the residual pitch exuded from the Doug-fir trees cause significant problems to the machinery and/or general efficiency of the sawmill? And if so, is it a good enough reason NOT to use Doug-fir trees? I'd also love to know if they collect this residual pitch and use/sell it as a byproduct and what solvents or techniques they use to remove/collect it from wherever it drips on? I'm doing a school research project on a veneer processing plant that predominantly process Pine logs, which seem to cause some problems with resin hardening on machines. I was wondering if you experience similar issues? Thank you!
@@frankmeiring1049 it sounds like you need to talk to them directly! That will give you the best info for your project. You can reach their company phone at 360-612-3745.
I was curious how plywood was made. Very clear and short explanation!
Glad you enjoyed it!
Very cool to watch this equipment in action. Do any of your veneers go to cabinet grade plywood or is it all construction grade?
Our understanding is that the Pacific Veneer team's customers are primarily using the veneer to make construction grade plywood.
Why do you put spaces between your dry veneer stacks in your stacker? 2:55
If we recall correctly, the mill uses the small pieces of wood to keep the veneer from bending too much in one direction.
It's great to know this
Do you struggle with tree resin/sap seeping out of the logs and onto machinery in the initial 1. conditioning of the logs or 2. veneer drying phase?
