NOVELTY - The apparatus has a shell-shaped dummy block (11) formed corresponding to the shape of mortar base where dice hole (7) is provided in center at the front-end of a piston (3). A jackup (5) of piston is provided with manual handle which withdraws/inserts the piston in container (6) to pack the biomass manure into billet the container in billet state. The piston is attached to the container through a spring (14) after the piston is pushed in the container and returned to original position by elastic force and deflection force of the spring.    USE - Domestic biomass manure pellet manufacturing apparatus.    ADVANTAGE - The dry manure pellet can be manufactured simply at low cost safely from the biomass of organic waste. The amount reduction of refuse and the reduction of administration cost can be achieved.    DETAILED DESCRIPTION - A biomass manure manufacturing machine ferments biomass and manufactures biomass manure whose water content is 10-20 weight%. The manufacturing machine includes a fermentation machine of double structure having an inner case container with perforated and filtration type stirrer which is taken in and out, and outer case container. The grinding small-piece formed by mixing an organic refuse and humus is fermented and taken out with the stirrer to cure and dry. A pellet manufacturing machine includes a cylinder having an insertion opening provided in upper side to throw biomass manure. The piston-shaped piston is arranged closet to the container from a direction opposing the dice hole to pack thrown-in biomass manure into the container. The piston is pressed in the container to compress the biomass manure in the container. The weight having 10 tons is lifted upwards vertically positioned state and the jackup of piston is positioned horizontally. The dioxin contamination is performed or the biomass to which heavy metal adhered is set separately to outside safety facilities. The slaked lime is mixed with dioxin and heavy metal, and injected into inner case container. The jackup of the piston is returned to original state by co-operating with the piston and dummy block by performing air vent of jackup after the biomass manure pellet is extruded from the dice hole.
