NOVELTY - Preparing bio-fungal wood pellet fuel, comprises (i) (a) processing of dry and fine hardwood sawdust, bio-fungal slag and wood shavings as raw materials, (b) processing of wet and fine raw materials, (c) processing of dry and crude raw materials, and (d) processing of wet and crude raw materials; (ii) fermenting bio-fungal package; (iii) stirring hardwood sawdust, bio-fungal slag and wood shavings; (iv) carrying out high temperature extrusion granulation; (v) cooling wood particles; and (vi) passing the cooled wood particles to a sieve-type filter, sieving out the debris, and packaging.    USE - The method is useful for preparing bio-fungal wood pellet fuel.    ADVANTAGE - The method produces fuel burnt under high flame which is pollution-free, and extends the combustion period.    DETAILED DESCRIPTION - Preparing bio-fungal wood pellet fuel, comprises (i) (a) processing of dry and fine hardwood sawdust, bio-fungal slag and wood shavings as raw materials, (b) processing of wet and fine raw materials, (c) processing of dry and crude raw materials, and (d) processing of wet and crude raw materials; (ii) sterilizing bio-fungal package, stacking, subjecting to fermentation, crushing, and drying; (iii) stirring hardwood sawdust, bio-fungal slag and wood shavings according to the ratio of 60:10:30; (iv) carrying out high temperature extrusion granulation by controlling a suitable temperature and pressure, then compressing the wooden meal to a certain diameter in a granulating machine, and extruding, then cutting to long round bar shaped pieces by passing by a round outlet to a cutting machine, and cutting the round bar into particles of certain length; (v) transferring the wood particles from a high temperature stainless steel conveyor belt to a counter-current air cooler, cooling at a higher than room temperature of 5-10 degrees C, and passing cool air from the cooler whose bottom part is provided with a strong fan; and (vi) passing the cooled wood particles into a sieve-type filter by batches, sieving out the debris, where the sieved out debris can be returned into the system for recycling, and then packaging the finished wood pellets, storing, and transporting.
