NOVELTY - The plant (1) has rough crusher that performs rough crushing of waste material. Cleaning dehydrator makes whirling force the crushed waste material, and carries out cleaning and dehydration. Chlorine-containing-resin removal apparatus determines and removes resin which contains chlorine among dehydrated waste materials based on reflectance of electromagnetic waves with cleaning dehydrator. Crusher crushes the waste material from which chlorine containing resin is removed. Pressure reduction fermentation-drying apparatus ferments and dries sludge at reduced pressure environment.    USE - Plant for manufacturing solid-fuel using sludge discharged from sewage treatment equipment, and flammables contained in general waste, business waste material, or industrial waste, such as waste plastic, wastepaper, and wood chip.    ADVANTAGE - By manufacturing the solid fuel using combustible lightweight articles and fermentation-drying sludge, the solid fuel can be manufactured by high recycling rate from waste material or sludge. Hence the terminal residue of the waste material can be reduced, and the demand of ultimate disposals can be reduced, and the construction of final disposal site can be suppressed. The chlorine containing material of sludge can be removed and generation of dioxin can be prevented. The need of heat-source apparatuses can be avoided so that the installation cost can be reduced. The emission of the carbon dioxide by use of fossil fuel can be prevented. The problem to which the recycling rate to the solid fuel of waste material falls can be prevented. The dry efficiency of pressure reduction fermentation-drying apparatus can be improved. The process chamber can be pressure-reduced, without affecting periphery environment according to odor. The formation of lump can be prevented and the to-be-processed object can be dried at favorable efficiency.    DETAILED DESCRIPTION - Molding machine is molded the fermentation-drying sludge fermented and dried with waste material crushed by crusher, and manufactured the solid fuel. Process chamber is accommodated the to-be-processed object in state to which enzyme is added, whose inside is pressure-reduced. Coil-shaped tubular portion is supplied with thermal medium, by which connects with rotating shaft in processing chamber interior so that rotation is possible. Heat stirring portion having blade is arranged at outer peripheral side of coil-shaped tubular portion. Jacket is formed in wall surface of process chamber, in which thermal medium is supplied. Pressure reduction value of other process chamber is set larger than pressure reduction value of initial process chamber. Drying process is performed continuously in drying chambers by equalizing the quantity of to-be-processed object which dries in drying chambers. Condensation portion is provided in processing chamber interior, to cool and condense the vapor from to-be-processed object. Air blower is used to suck the air of processing chamber interior of pressure reduction fermentation-drying apparatus, and supply the sucked air to boiler (6) as combustion air. Infrared irradiation portion is used to irradiate the infrared rays as electromagnetic waves to to-be-processed object on mounting surface of transfer apparatus. Position detection portion is used to detect the position of to-be-processed object where reflected wave is detected by reflected wave detection portion. Material determination portion is used to determine the material of to-be-processed object based on spectrum distribution of reflected wave which reflected wave detection portion detected. Swiveling type classification machine is used to classify the waste material into heavy article, lightweight article, and small diameter article according to the difference between dimension and specific gravity. Molding machine is screw type molding machine, ring-die type molding machine, or flat-dies type molding machine.
