5.2. COMPARISON BETWEEN CANADA AND EUROPE 5.2.1. Profiles of Companies Some of the differences between the Canadian and European respondents could be due to the fact that different categories of respondents were surveyed. While the Canadian study focused exclusively on wood product plants or divisions with kiln drying facilities, the European study surveyed: a) kiln users, b) suppliers of equipment, c) users of kiln dried timber, and d) researchers/teachers. However, the majority of European responses (84.2%) came from kiln users (i.e., companies with kiln drying facilities) and therefore a comparison is meaningful. In addition, regional differences (see figures 15 and 16) that were found in the type of species dried (softwoods vs. hardwoods) and the number of employees might also account for some differences. That said, the Canadian survey was designed to maximize meaningful comparisons. 5.2.2. Important Issues For Both Regions The results of the t-tests (alpha = 0.05) show that there were only four drying issues that were not statistically significant different between the two regions. These issues were all considered from moderately important to important in both Canada and Europe. Therefore, it can be concluded that those four drying issues cause serious concerns in the wood products industries of the two continents and likely on a global scale, as well (Avramidis, personal communication). The four issues are: • Achieving target moisture content. • Use of optimized schedules (to reduce degrade and drying time depending on species and size). • Electrical energy consumption (mostly used to operate fans). • Type of kiln control unit (manual or automatic). In view of these conclusions, it is suggested that all four drying issues receive the proper amount of attention, as far as research priorities are concerned. This is advisable, since it is sometimes possible to transfer existing solutions between regions, without having to conduct new drying research. 91PDF Image | KILN DRYING PROBLEMS AND ISSUES IN CANADA
