NOVELTY - A rapid composting machine (1) comprises: shell body and fermentation unit. The fermentation unit comprises fermentation tank for fermenting raw materials; stirring unit; driving unit used to drive the stirring unit to stir mix a ferment raw material; and heating unit for maintaining the fermentation tank space at a certain temperature in order to accelerate the composting fermentation.    USE - For rapidly manufacturing of compost (claimed).    ADVANTAGE - The composting machine greatly shortens the organic compost manufacturing time; provides high quality and low cost organic compost; and also provides little pollution.    DETAILED DESCRIPTION - A rapid composting machine (1) comprises: shell body (10) and fermentation unit. The top of the shell body has port for inputting the materials to be fermented, and the bottom part of the shell body has outlet for complete fermentation output product. The fermentation unit covers from the outer shell body and comprises fermentation tank (21), stirring unit, driving unit and heating unit (24). The fermentation tank comprises an inlet port (211) connected to the outer shell of the entrance to enter to be fermented raw materials; and a discharge port. The bottom of the fermentation tank comprises semicircle for outputting complete fermentation products and cloth plural holes, in order to facilitate the flow of gas circulation. The stirring unit comprises: a stirring blade axis, provided in the center position of the fermentation tank, where the one end of the stirring blade axis is pivotally attached to container bearing seat of the shell body, and the other end is pivotally connected to a drive shaft coupling. Several stirring vanes are fixed to the ring disposed on the stirring blade axis, where the several stirring blades connecting plate are used to connect the several stirring blade. The driving unit is provided at one side of the fermentation tank and is pivotally connected to the drive shaft coupling which is used to drive the stirring blade axis of rotation. The heating unit is located in the bottom of the fermentation tank and is used to heat the fermentation tank, where a fermentation of raw material through the opening of the outer shell into the fermentation tank through the driving unit to drive the stirring unit to stir mix a ferment raw material, and by the heating unit to maintain the fermentation tank at the specific temperature. An INDEPENDENT CLAIM is included for rapidly manufacturing of compost by using composting machine involving collecting the fermentation raw material to be fermented, in accordance with to be fermented characteristic adjusting the carbon and nitrogen ratio of raw materials, adjusting the water content of 40-60%; adding compost fermenting agent, uniformly mixing, putting obtained mixture into fermenting machine, and then fermenting for 2-8 hours at 60-90 degrees C with stirring speed of 10-30 rpm. The fermentation raw material is agriculture organic waste or city garbage waste organic matter.    DESCRIPTION OF DRAWING(S) - The figure shows a front view of rapid composting machine.
