Wooden pallet drying is an important issue for
both pallet producers and users. Many pallet user industries have
very precise requirements concerning moisture content, including
the paper and cardboard, chemicals, plaster, cement and food industries.
This project was concerned with developing improved
and more economical methods for pallet drying. Partners conducted
an in-depth survey to determine the basic needs of end users and
developed methods for testing and measuring the moisture content
of pallets. These methods can be included within pallet production
processes or can be used for quality control at pallet delivery.
Methods for estimating air-drying time and for calculating prime
costs were also elaborated and can be integrated into the industrial
manufacturing process, helping to optimise storage management. Finally,
an artificial drying process was developed, as well as a new process
for drying via the continuous kiln.
Many of the results have practical industrial
applications and partners say the new method will also lead to reduced
litigation and improved relations between manufacturers and users.
The environmental benefits are also very significant.
