Introduced: September 1968
Description
F26B encompasses mechanical and thermal processes for removing moisture or other liquids from solid materials and objects. This subclass covers drying equipment and methods applicable to diverse solids such as textiles, paper, wood, chemicals, minerals, and agricultural products. Specific technologies include drum dryers, spray dryers, tunnel dryers, vibrating dryers, and rotary dryers, as well as drying by heat application or mechanical removal of liquid. F26B excludes drying by evaporation alone (covered under F26A) and focuses on apparatus and processes where solids are the primary product being dried rather than liquid recovery.
