Excerpt from Manual of Design and Installation of Forest Service Water Spray Dry Kiln The 'best thing that can be said. Of any dry kiln is that when it is run by a properly informed operator the temperature, humidity, and circulation are constant and uniform. In an endeavor to pro duce a kiln in which each Of these could be regulated independently Of the others, the Forest Products Laboratory designed and devel oped the Forest Service Humidity Regulated Water Spray Kiln, 1 described in this bulletin. The principle Of forced circulation and humidity control by means Of sprays Of water was the basis Of the first patent taken out in 1912 and is the main feature Of the present kiln. This dry kiln is well adapted to commercial use in the kiln drying Of refractory hardwoods Of large dimensions and Of green lumber Of all kinds, and has attracted attention wherever commercial practice has been forced to realize that drying equipment incapable Of close operation will not dry green lumber economically. Experience has Shown that the details Of good design and work manship are Often disregarded, with the result that the kiln fails to function as intended. By adhering to the principles herein set forth any competent engineer should be able to design or construct an installation Of the Size suited to the peculiar needs of a given plant.
