    • 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.

    • PURPOSE:To prevent deterioration of filtration capacity by using accessory material used for aerobic fermentation treatment as a filter medium and holding solid contained in sewage on the filter medium, and also performing work as the accessory material similarily to the case of aerobic fermentation treatment, decomposing and removing solid. CONSTITUTION:When sewage generated from a pig-pen is uniformly spread on the upper surface of a filter medium 1 such as sawdust built-up on a stainless steel network 8 and victoria lawn 7 in the lower part of a filter tank from a sewage spray pipe 3 by a pump, solid contained in sewage is almost filtered and held on the upper layer part of the filter medium 1. Filtrate is passed through a distributing water pipe 10 thereof and stored in a receiving tank 11 and separation of liquid and solid is performed. The solid held on the upper layer part of the filter medium 1 is agitated and mixed by actuation of an agitating and cutting device 2 and aerobic fermentation treatment is performed. In this case, when filtration capacity is deteriorated in a state wherein the present agitation depth is maintained, the agitation depth of an agitation shaft 5 is deepened by an elevating/lowering device 6 of the agitation shaft and the clogging part is agitated and mixed to perform aerobic fermentation treatment. Thereby deterioration of filtration capacity is prevented.
