<p>The invention provides a chamber ( or tank ) sealable when closing its cover (door), in which green lumber, agricultural products and/or earthwares to be dried can be artificially dried to the desired degree, or in which they can be provided with insect-proof and/or rotten-proof treatment or coloring treatment as well as said drying treatment. Said chamber has means for measuring the drying degree ( moisture content ) of the material to be dried and means to heat, moisture or dampen the inside of said chamber and to reduce the inside pressure of said chamber. Such processes ( drying, moisturizing and pressure reduction) are carried out in several steps, thereby changing the atmospheric conditions in said chamber in phased programs. This control is performed by checking the drying condition (degree) of the material as it is in said chamber. Moreover, unmanned operation is thereby easily secured by changing said drying condition to electrical signals and automatically setting the running conditions with said signals as input.</p> |
