Kind Code:

A1

Abstract:

[Problem] To remove the need for a high-temperature/high-pressure treatment environment in the use of hydrolysis treatment to treat waste food-residue that is discharged in large quantities, and enable suitable, inexpensive hydrolysis treatment at high treatment efficiency, in a manner suitable for the soft but viscous properties of the waste food-residue that is to be treated. [Solution] The invention comprises: a granulate mixture formation step in which, within a cylindrical body, waste food-residue and dewatered sludge are mixed by stirring to form a mixture, and during that formation the waste food-residue and the dewatered sludge are granulated, thus forming a granulate mixture in which the granulated waste food-residue is dispersed in the granulate dewatered sludge; and a recycling raw material formation step in which the granulate mixture and steam are introduced into a reactor, and mixed by stirring, and the waste food-residue in the granulate mixture is hydrolyzed into a low-molecular-weight material, thus forming a granulate pelletized raw material in which the hydrolyzed waste food-residue is dispersed in the hydrolyzed granulate dewatered sludge.
