NOVELTY - The aerobic composting device comprises a reaction barrel (3), a reaction barrel cover (2), a water cycle heat exchanger, an air flow meter, a water tank and an oxygen detector. The reaction barrel contains kitchen waste material, and is equipped in a thermometer/hygrometer. An outside of the reaction barrel is coated with a layer of thermal insulation material (1). An exhaust gas generated in the composting process is ejected by the reaction barrel cover on a dumped guide pipe (8). A transudatory liquid in the composting process is ejected by a percolate delivery line (12).    USE - The device is useful for aerobic composting of kitchen waste material to produce compost product, which is useful for agriculture, forestry and garden.    ADVANTAGE - The device is capable of rapidly and efficiently composting the kitchen waste material with less energy consumption and without pollution to the environment thus improving the quality of the compost product.    DETAILED DESCRIPTION - The aerobic composting device comprises a reaction barrel (3), a reaction barrel cover (2), a water cycle heat exchanger, an air flow meter, a water tank and an oxygen detector. The reaction barrel contains kitchen waste material, and is equipped in a thermometer/hygrometer. An outside of the reaction barrel is coated with a layer of thermal insulation material (1). An exhaust gas generated in the composting process is ejected by the reaction barrel cover on a dumped guide pipe (8). A transudatory liquid in the composting process is ejected by a percolate delivery line (12) on the reaction barrel. An ingress pipe (13) and an air compress pump are adapted for proving air to the reaction barrel. A bottom of the reaction barrel is equipped with a gas distribution disk. Air enters the bottom of the reaction barrel through the air compress pump, the air flow meter and the water tank by the ingress pipe, and enters the reaction barrel by the gas distribution disk on the bottom of the reaction barrel. The water cycle heat exchanger is an interlayer located between the reaction barrel and the thermal insulation material, and adjusts a temperature refrigerator for adjusting the humidity in the reaction barrel by the water bath in the water cycle heat exchanger. The exhaust gas ejected from the dumped guide pipe passes through the oxygen detector to detect oxygen concentration in the exhaust gas. An outlet of the water cycle heat exchanger is connected with a first three-way valve. An inlet of the water cycle heat exchanger is connected with a second three-way valve. The first three-way valve is connected with a water inlet of a water cycle heating device and a water cycle cooling device. The second three-way valve is connected with a water outlet of the water cycle heating device and the water cycle cooling device. The thermometer/hygrometer is connected with a temperature/humidity sensor outside the reaction barrel. One end of the humidity sensor of the temperature/humidity sensor is connected with the air compress pump. One end of the temperature sensor is connected with the first three-way valve and the second three-way valve. The air compress pump adjusts the value of the ventilatory capacity by humidity numerical value. The first three-way valve and the second three-way valve select the source of the water bath. A water temperature of the water cycle heating device is 80 degrees C. A water temperature of the water cycle cooling device is room temperature. The thermometer/hygrometer is divided into an upper thermometer/hygrometer and a lower thermometer/hygrometer. The upper thermometer/hygrometer and the lower thermometer/hygrometer are separately inserted in the upper part and lower part in the middle of the waste material. An INDEPENDENT CLAIM is included for a method for controlling an aerobic composting device.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a composting device.
