NOVELTY - Processing tea resources, comprises (a) subjecting tea leaves to hot water extraction, and performing solid-liquid separation; (b) performing instant tea production line; (c) performing wastewater sewage treatment, and separating water and sludge; (d) drying sludge; (e) drying tea leaves by diaphragm frame filter press; (f) drying tea leaves; (g) mixing dried tea leaves and sludge, and extruding-molding; and (h) taking the resulting tea leaves-based biomass pellet fuel used in biomass water heaters and biomass fuel stove, where biomass water heaters provides hot water during tea extraction.    USE - The method is useful for processing tea resources.    ADVANTAGE - The method saves energy, is environmental friendly, has comprehensive utilization property, and produces tea- leaves-based biomass pellet fuel which completely meets the requirements of production process and savings (all claimed).    DETAILED DESCRIPTION - Processing tea resources, comprises (a) subjecting tea leaves to hot water extraction, and carrying out solid-liquid separation to obtain tea portion and tea leaves portion; (b) subjecting the tea portion to instant tea production line to obtain instant tea product, where the process produce waste water; (c) subjecting the wastewater produced in the step (b) to wastewater sewage treatment, and separating water and sludge to meet emission standards, and discharging the clear water; (d) drying the resulting sludge by passing through a diaphragm frame filter press; (e) drying the tea leaves portion of the step (a) by passing through diaphragm frame filter press; (f) drying the dried tea leaves by passing through a triple pass dryer drum; (g) mixing the dried tea leaves and sludge, and extruding-molding in an ring mold pellet machine to obtain tea leaves-based biomass pellet fuel; and (h) taking the resulting tea leaves-based biomass pellet fuel used in biomass water heaters and biomass fuel stove, where the biomass water heaters provides hot water during tea extraction process, and the biomass stove provides hot air for drying tea leaves in the triple pass dryer drum.
