The application relates to a method and apparatus for manufacturing a natural fiber based staple fibers. The application further relates to the staple fibers, staple fiber based raw wool and products comprising such. A method comprises providing a cellulose suspension (101, 310, 510) including water, refined cellulose fibrils and at least one rheology modifier, directing the cellulose suspension through a nozzle (102, 320, 520) onto a surface (300, 400, 500), drying the cellulose suspension onto the surface (103, 300, 400, 500) for forming a fiber (350, 550), and cutting the cellulose suspension on the surface for forming staple fibers (105).

Method and apparatus for hot air drying granular polymeric resin material records heating air temperature at a heating air outlet, computes air flow rate through a hopper, maintains desired throughput of granular material being dried in the hopper until heating air outlet temperature is stable, and thereafter maintains air flow rate through the hopper and monitors that air flow rate to adjust the air flow rate to maintain a computed preferred air flow rate through the heating hopper.

An exhaust quenching system is provided for use in connection with an asphalt concrete production plant having a dryer for drying aggregate material, an exhaust gas outlet conduit for discharge of exhaust gases from the dryer, and a dust collection assembly that is adapted to receive exhaust gases and entrained dust from the dryer via the exhaust gas outlet conduit. The exhaust quenching system is adapted to effect evaporative cooling of the exhaust gases in the exhaust gas outlet conduit upstream of the dust collection assembly.

Apparatus and method for drying spent nuclear fuel loaded in a cavity of a canister. A non-reactive gas discharged from the canister is selectively circulated through one of a contaminated circulation system and a non-contaminated circulation system according to a measured radiation dose rate.

Method and apparatus for drying granular resin material by heating compressed air to a temperature prescribed for gas separation membrane operation, presenting the heated compressed air to a membrane separating out oxygen-size and smaller molecules to provide a stream of gas molecules of at least nitrogen-size at a pressure substantially that of the compressed air, heating the stream of gas molecules of at least nitrogen-size to a temperature at which dew point of the stream is no higher than −40 degrees F., and introducing the heated stream of gas molecules into a chamber for upward flow to atmosphere through granular resin material in the chamber.
