TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The combustible cellulosic fibrous material is selected from wood chips, cherry pits, olive pits, sugar-cane bagasse, sweet sorghum bagasse, grass clippings, and/or fur trees.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Apparatus: The drying unit is a rotary dryer (preferably a spinning tube dryer). The heat source comprises a system of tubes (preferably bundled tubes) that conveys the heat source. The heat source is saturated steam. Preferred Method: In step (a), the unprocessed combustible cellulosic fibrous material is continuously fed, while the material is loosened and flattened. In step (b), ferrous material and impurities are removed from the unprocessed material. In the method (M1) and step (c), the heat source is applied at 170 - 185degreesC inside tubes of the tube dryer and results in temperatures of 135 - 140degreesC on the external surfaces of the tubes in the drying unit; at a pressure of 8.34 - 9.81 bar (8.5 - 10 kgf/cm2) inside the tubes. The material remains inside the tube dryer for 12 minutes, at 4 revolutions per minute (rpm), using 2 - 3 metric tons of steam per hour. After the combustible cellulosic fibrous material leaves the tubular bundles, it is insufflated in counter flow with hot air by a duct coming from a heat radiator fed by saturated steam. In step (c), the hot and humid gases are removed on the opposite side of the entrance of the dryer by a duct with forced exhaust, and sent to a cyclone, or similar equipment; in which the solid particles (powder) are separated and sent to for burning by the boiler. In step (d), the dried combustible cellulosic fibrous material, with a humidity of (13 - 20)% is continuously fed to the pelletizers; in which the material receives an injection of saturated steam, and then enters the pressing system of the pelletizer. After step (d), the material pellets are removed from the pelletizers, by a variable-speed cleated or similar type conveyor belt. In step (e), the pellets are sorted according to their size, and/or any rejected material at the sifter, together with any excess dried combustible cellulosic fibrous material from the feeding conveyor belt is returned to the feed box to be reused in the method; the pellets are cooled down to room temperature of 20 - 40degreesC. In step (f), the final combustible cellulosic fibrous material pellets, having a humidity of (9 - 13)% and a density of (0.55 - 0.6) g/cm3 are advanced to a storage system. The method (M2) further involves: storing the dried combustible cellulosic fibrous material pellets. The method is a fully automated and/or continuous method. In the device (D2), the continuous feeding unit comprises a cleated or similar type conveyor belt, a feed box, and a sprayer. The feed box can hold a 15-minute supply and has a rectangular flat-wall, a flat-bottom, and a cleated or similar type conveyor belt. The cleaning unit comprises a cleated or similar type conveyor belt, an electromagnet, and a di-stone. The electromagnet has a minimum magnetic capacity of 1500 gauss, and the di-stone is a rotating machine consisting of 5 - 8 perpendicular axes with star-shaped knives that counter-rotate. The drying unit comprises a cleated or similar type conveyor belt, a spinning tube dryer, an insufflating system, and an exhaust system featuring cyclones. The spinning tube dryer is fitted with deflectors positioned at 45degrees, attached to the tube bundles. The minimum spacing between the tubes is 75 mm. The pelletization unit comprises a cleated or similar type conveyor belt, sloping spouts, conditioner of the pelletizer, the pelletizers, and a variable-speed cleated or similar type conveyor belt. The sloping spouts have adjustable gates and magnetic plates. The conditioner is a spinning cylindrical metal box with a diameter of 450 mm, fitted with wings and driven by a motor of 5 hp. The pelletizer comprises a pressing system, a cast-steel case; holding primary shafts, hollow mold shafts, compacting rollers and motor, and main shaft that fixes the two compacting rollers and the scarpers. The compacting roller has a diameter of 140 - 220 mm, an eccentric shaft, and a device with adjusting regulators and a metal shield pressing, having a thickness of 15 - 40 mm and grooves 2 - 5 mm deep and 2 - 5 mm wide, and spaced 8 - 12 mm apart. The pressing system of the pelletizer has a mold rotating at 360 rpm, two pressing rollers, regulators and is driven by a motor of 125 hp at 1750 rpm. The mold is fixed at the hollow rotating shaft, is driven by gears and an electric motor with power of 100 - 400 hp, at 220 - 420 rpm, is a metal ring with a flange for fixing on the hollow shaft and a surface with various holes having various sizes; and has a mold diameter of 520 - 820 mm, a diameter of mold holes of 4.76 - 19.05 mm (3/16 - 3/4 inches), a width of the track of the molds of 100 - 220 mm, and umber of holes in the molds of 860 - 4600. The sorting and second drying unit comprises a variable-speed cleated or similar type conveyor belt, a vibrating sifter, a cooler with a cleated conveyor belt having a perforated screen, and an exhaust system with a cyclone. The device further comprises a storing unit comprising a cleated or similar type conveyor belt, and big bags or silos. The pelletization unit and sorting and second drying unit are connected to the drying unit, via a cleated or similar type conveyor belt. The units are integrated into one system.
