NOVELTY - A soil-mixture injection portion (13) is arranged in the lower end of an inclined rotary cylinder (11), to supply soil mixture. The soil mixture is granulated by a spiral portion (14) set inside the cylinder. A soil dumpling discharge portion (15) is formed in the top surface of the rotary cylinder to eject soil dumpling which is molded from the soil mixture.    USE - The apparatus is useful for manufacturing soil dumpling (claimed) for use in soil reinforcement material.    ADVANTAGE - Enables efficient manufacturing of soil dumpling of predetermined size, by using the soil mixture. The soil mixture is granulated by the spiral portion and dried simultaneously and thereby the productivity is raised.    DETAILED DESCRIPTION - The soil mixture is formed by mixing sludge of organic materials such as rice bran, chaff, oil cake, fish meal, treacle, soil and useful micro-organisms. The outer wall portion of the cylinder is rotated through a roller. A projection protruding from the outer wall of the cylinder, contacts the roller intermittently so as to apply impact force to the cylinder. A mixer (16) is arranged in the soil-mixture injection portion of the cylinder, to supply soil mixture. A stirring blade (18b) is arranged in the periphery of a rotating drum (17) arranged in the mixer. A cutter (19) cuts preset length of the rod-like soil mixture extruded from the soil dumpling discharge portion. The soil mixture cut by the cutter is supplied to a conveyor.    An INDEPENDENT CLAIM is also included for soil dumpling which is formed by using soil mixture in the soil dumpling manufacturing apparatus in dry fermentation conditions. The retention temperature ranges between 15-35degreesC and the holding time is set in the range of 15-25 days.
