There you will find the time-controlled schedule. Equalizing and conditioning treatments may be added as needed. This is a very common type of lumber dry kiln currently being used in the United States and Canada and will continue to dominate these markets for years to come. Other drying systems are available and enjoy varying degrees of success in the United States and Canadian markets. A few schedules have been suggested for drying selected southern pine products in direct-fired kilns.
Temperatures are frequently lower than steam-heated kilns.
The majority of the suggested schedules for steam kiln are adaptable for use with the dehumidification kilns. We believe this procedure is adequate to develop an initial kiln schedule, with modifications then made based on the drying results. At this time, we cannot comment on the usefulness of these schedules to the vacuum or RF vacuum-drying systems. Dry Kiln Operators Manual. 197 p., illus.
