    • PROBLEM TO BE SOLVED: To effectively produce granular fermented chicken droppings having high hardness by granulating the fermented chicken droppings under specific conditions using a horizontal type extrusion granulating machine with a disk type die. SOLUTION: The die varying in the shape of upper part holes and the shape of lower part holes are used. The upper part of the die is columnar and the hole size is 3 to 5mm. The lower part thereof is columnar or circular truncated cone and the ratio of the hole diameter of the lowermost part/the hole diameter of the upper part is specified to 1.3 to 1.8. The ratio of the depth of the lower part holes/the depth of the upper part holes is specified to 1 to 5. The moisture of the chicken droppings is specified to 18 to 28wt.% at the time of granulation. The fig. illustrates a schematic diagram of granulation. This granulating machine is classified to a roll type extrusion granulating machine. A disk-shaped perforated plate is used for the dies 1. The machine is installed horizontal. Plural pieces of radially disposed rolls 2 are rotated by the friction resistance with the die 1 while these rolls revolve. The fermented chicken droppings 3 supplied onto the die from a hopper 5 are pressurized between the die and the rolls and are extrusion molded from the die holes. The granular chicken droppings 4 are discharged from an outlet 6.
