There are 4 parts (objectives) to the SWI research programme. Detail on the research focus within each objective is provided below – this is constantly changing as work is completed and new priorities established.
Appearance
- CODIL for control of resin showthrough and resin bleed.
- Ultrasound detection of intra-ring checking and resin pockets.
- Automated location of pith on log ends using digital photography. Applies to both appearance and structural mills.
- Head rig open face grading system. Applicable to appearance manufacturers for resinous defects and for structural manufacturers processing a mix of pruned and unpruned logs.
Logs & Stems
- Stem and log segregation technologies to get the right log to the right mill and to optimise breakdown for structural and appearance product performance.
- Internal defect recognition for green logs to detect 3D distribution of resinous defects, compression wood & spiral grain, & therefore log rotation for optimal sawing patterns.
Structural
- More efficient structural lumber manufacturing with higher yields of better performing performance guaranteed products (using less energy and less water).
- Green segregation technology for key wood properties to identify poor material and get it out of the manufacturing process early.
- The need for on line scanning for delivering warp stable solid wood products.
Energy Drying & Water
- Energy Challenge – 5% savings (see separate tab).
- Reduced energy, water usage and emissions in kiln drying of lumber (including residues utilisation options).
- Optimisation of existing batch drying processes.
- Smarter monitoring of kiln conditions and endpoints.
- Controlling kiln emissions, water & energy.
- Work on Continuous Kiln development.
