NOVELTY - The recycling system consists of a production unit (A) for separating foreign materials from waste foodstuffs and for producing deoiled, dry fodder. A production unit (B) is provided to produce methane gas and biomass from the waste foodstuffs. A production unit (C) comprising a mixer type fermentation apparatus produces fermented fodder.    USE - The recycling system is useful for recycling waste foodstuffs such as bean curd lees, noodles, fruits such as grapes obtained from food processing plants, to produce methane gas, biomass, dry fodder and fermented fodder for livestock.    ADVANTAGE - Enables efficiently recycling the waste foodstuffs into methane gas which is used as fuel, and fodder for livestock, by combining the different production units in the recycling system.    DETAILED DESCRIPTION - The production unit (A) has a processing tank which receives waste foodstuffs from which foreign material has been separated. Water of temperature 90 degrees Centigrade or more is sprayed on foodstuffs, in the processing tank, to remove oil, salt from the foodstuffs. The production unit (A) has a rotary, cylindrical tank in which the foodstuffs are heated by steam, for drying the foodstuffs, so as to produce dry fodder. The production unit (A) has a horizontal centrifuge to separate the broth containing oil, into solid and liquid. A separator is provided to separate the liquid into sap, oil and sludge. A cyclone and a scrubber are provided to remove particles from steam ejected from the drying tank. Foodstuffs are distributed inside the tank, by rotation of the tank. The production unit (B) has a heating and dissolution tank in which foodstuffs are heated and dissolved to form a solution. A methane fermentation tank receives the solution and produces methane gas. An algae culture tank which cultivates euglena, receives a portion of methane gas and the digestive liquor of the gas, to produce biomass. The production unit (C) has the mixer type fermentation apparatus in which lactic acid-fermentation of foodstuffs is performed in the atmosphere of nitrogen gas supplied from a nitrogen gas generator, using latobacillus. An aspirator is connected to a collection bag which collects the fermented fodder.    DESCRIPTION OF DRAWING(S) - The figure shows the schematic view of the waste foodstuffs recycling system.
