NOVELTY - The installation (1) has a processing apparatus (2) that crushes the used paper sanitary goods and stirs the goods with ferment microbe, to produce a process product and discharge the process product from a discharge port (5). A pellet forming apparatus (3) forms fuel pellets by press-fitting the process product injected from a product insertion opening in several die holes. A conveyor (4) conveys the process product discharged from the discharge port of the processing apparatus to the product insertion opening of the pellet forming apparatus.    USE - Solid-fuel production installation for producing pellet-form solid fuel from used paper sanitary goods such as used paper diaper for small children and adult, discharged from hospital, retirement home, nursing home and home. Can also be used for producing pellet-form solid fuel from used paper mask, used paper pad, used paper sheet and used paper medical clothing.    ADVANTAGE - The operating cost of the solid-fuel production installation can be reduced, by using a simple arrangement.    DETAILED DESCRIPTION - The installation has a processing apparatus comprising an exhaustion unit that exhausts atmospheric gas in the processing tank into which the used paper sanitary goods are thrown, for generating negative pressure inside the processing tank. A deodorizing unit deodorizes the odor gas using the exhaustion unit. A heating unit performs heat-sterilization of the fermentation processed material for a predetermined time, so that the fermentation processed material is made into a process product, while heating the crushed material in the processing tank, by adjusting the water content of the crushed material and setting the crushed material as fermentation processed material. Several die holes are formed in the disk-shaped die of the pellet forming apparatus, such that the holes are extended and penetrated to the center axis direction. The process product is press-fitted into the die hole, by rolling the board surface of the die, for forming a fuel pellet with a frictional heat, so that the fuel pellet is used as a fuel of the combustion apparatus of the reprocessing facility.
