At this time, the regenerated fuel is extruded into a rod shape, cut into a suitable length by using a separate cutting device, and is produced in the form of a lump using a pellet-type or roll-forging method.

However, in this manufacturing apparatus, the flammable waste supplied through the hopper through a free-fall type free-weighting method without a separate injection device is not constantly introduced into the screw case, that is, the flammable waste is not exactly supplied to the screw thread of the screw, The supply of flammable waste becomes uneven due to the idle rotation of the screw thread, and such uneven supply is critical to the densification of the product and bubble phenomenon, which is the main cause of deteriorating the quality of the regenerated fuel.

In addition, the auxiliary heating unit in the screw is provided with a supply pipe extending over the screw electric length so as to supply the heating medium supplied through the conduit from the auxiliary heater separately provided from the outside to the tip of the hollow screw, Has a problem that the end portion thereof is left free in the hollow screw without supporting structure and the relatively long length of the supply pipe flows in the screw and is structurally unstable so that the supply pipe is easily broken by the external force .

In addition, in the molding apparatus using the roll forging method, a plurality of coarse-shaped regenerated fuels are discharged to the conveying conveyor through the chute, where the discharged lump-shaped regenerated fuels have a slight viscosity on the surface, There are many problems such as a phenomenon of sticking to each other and workability is deteriorated due to the addition of a post-work for separating them separately.
