NOVELTY - An organic waste processing apparatus comprising multiple reactors that enable vapor decomposition of organic waste using steam from the boiler, is new.    USE - For decomposing organic waste e.g. foodstuffs waste material, agricultural, stock raising waste material, fishery waste material, etc., to produce manure.    ADVANTAGE - Organic waste is thermally decomposed in a short time, and provides an efficient method of recycling an organic waste. Easy to convey by drying the decomposed product.    DETAILED DESCRIPTION - An organic waste processing apparatus comprising multiple reactors that enable vapor decomposition of organic waste using steam from the boiler, is new. A sorter classifies the organic waste (U) and the sorted organic waste is crushed by the crusher. The crushed waste is passed into the reactors (R1-Rn). The reactors have a heater to heat the organic waste containing water content. The process conditions in the reactors result in the sterilization of the organic waste. The reactors have a boiler for carrying out vapor decomposition of organic waste by rotating the rotary device using steam (J) from the boiler. A manure formation unit (H) and fuel formation unit produce manure decomposition products (B) and fuel decomposition products respectively from the decomposed products of the reactors. A dryer dries the decomposed product from the reactors. Multiple cascade connection units enable vapor decomposition, and vapor-liquid separation unit performs separation of vapor-liquid about the vapor ejected from the reactor.    INDEPENDENT CLAIMS are also included for the following:    (1) an organic waste processing method; and    (2) a reactor for vapor decomposition.
