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