WOOD PELLET MANUFACTURING METHOD UTILIZING AGRICULTURAL AND LIVESTOCK WASTE

摘要

The present invention relates to a wood pellet manufacturing method utilizing agricultural and livestock waste. According to the present invention, crop stems discarded after fruit harvesting and forest tree byproducts are turned into a chip by being crushed with a crushing machine, and then foreign matter screening is performed. Then, resinous pine tree knot powder which is rich in resin, highly exothermic, and highly combustible and animal oil and fat as livestock waste is added and press molding, drying, and the like are conducted. Then, wood pellet with a high heating value is produced, which can be used as a fuel in, for example, thermal power plants, firewood boilers, and fireplaces. The wood pellet manufacturing method utilizing agricultural and livestock waste according to the present invention includes: a step in which a chip is produced with a crushing machine and by mixing of forest tree byproducts and agricultural waste; a step in which foreign matter screening is performed with the produced chip put into a screener; a step in which resinous pine tree knot powder and animal oil and fat are added to the foreign matter-screened chip; a step in which the resinous pine tree knot powder- and animal oil and fat-added chip is put into a wood pellet production machine and a pressure of at least 5,000 kg is applied for wood pellet production; and a step in which the produced wood pellet is put into a drying facility and dried to a moisture content of 15% or less.;COPYRIGHT KIPO 2016
