NOVELTY - Organic matter fermentation drier comprises: a heating system (1) with superconductive heater for heating air; a fermentation system (2) with fermentation barrel equipped with an air inlet for inputting air heated by the superconductive heater; a heat recycling system (3) with vacuum superconductive tube heat exchangers; a waste gas treatment system (4) comprising calcium hydroxide, ferric oxide and activated carbon for absorbing carbon dioxide, sulfur dioxide and ammonia respectively; and a vacuum drying system (5) with vacuum device for controlling the vacuum degree of fermentation barrel.    USE - Used as an organic matter fermentation drier.    ADVANTAGE - The two-grade heat exchanger installed for recycling the heat abundantly and reducing the evaporation heat improves the heat efficiency and the heat exchange efficiency of the fermentation drier, thus reducing the fermentation cost and conserving energy.    DETAILED DESCRIPTION - Organic matter fermentation drier comprises: a heating system (1); a fermentation system installed on the downstream of the heating system; a heat recycling system installed on the downstream of the fermentation system (2); a waste gas treatment system (4) installed on the downstream of the heat recycling system (3); and a vacuum drying system (5) connected with the fermentation system. The heating system comprises a superconductive heater for heating the air. The fermentation system comprises a fermentation barrel equipped with an air inlet for inputting the air heated by the superconductive heater. The heat recycling system comprises two groups of vacuum superconductive tube heat exchangers connected in series. The heat exchanger comprises a heat absorption cavity and a heat dissipation cavity arranged separately. In the first group of the vacuum superconductive tube heat exchangers, there is water to pass the heat absorption cavity and there is waste gas produced by the fermentation system to pass the heat dissipation cavity. In the second group of the vacuum superconductive tube heat exchangers, there is air to pass the heat absorption cavity and there is the waste gas whose heat is dissipated primarily to pass the heat dissipation cavity. The air absorbing with the heat is delivered to the superconductive heater and the waste gas produced by the fermentation system comprises carbon dioxide, sulfur dioxide and ammonia gas. The waste gas treatment system comprises calcium hydroxide capable of absorbing carbon dioxide, ferric oxide capable of absorbing sulfur dioxide and activated carbon capable of absorbing ammonia gas. The vacuum drying system comprises a vacuum device for controlling the vacuum degree of the fermentation barrel and sucking the moisture of the fermentation barrel and an industrial chiller for condensing the sucked moisture into the water.
