Abstract:
1. A process of drying crushed cane or other bagasses for subsequent briquetting comprising: receiving humid bagasse in a dosing hopper ( feeding the humid bagasse to the screw conveyor which is inclined at 45° ( feeding the humid bagasse to a rotary dosing valve ( discharging the humid bagasse within a hot air funnel ( dropping the hot air and humid cane bagasse into a cylindrical drying tank ( contacting the humid bagasse with a jet of hot air, having a temperature of the order of 500° C., causing instantaneous volatilization of proteins (sugars), lifting the humid bagasse and exposing the humid bagasse to hot air in a front chamber ( said front chamber ( lifting and driving slightly-humid cane bagasse to the bottom of the final drying chamber, sucking almost-dry bagasse in suspension out by pair of centrifugal blowers ( dropping it into a cyclone-type separator filter ( separating humid air from cane bagasse, having a humidity of the order of 10 % and a temperature of the order of 40 to 50° C., allowing cane bagasse to fall under gravity into a hopper ( subsequently feeding the cane bagasse to a screw conveyor ( discharging the cane bagasse in the return direction, in the direction of the hopper ( dropping said dry cane bagasse powder into distributor trough ( similarly dropping it into two feeder hoppers ( dropping the powder into air ducts swept by blowers (
