NOVELTY - Aerobic fermentation reactor comprises circular inner part of reactor and end cover and sleeve, where the fermentation reactor is provided with an upper end cover and lower end cover. The fermentation reactor is connected with feed valve (19) and discharge unit (01), where length of fermentation reactor is greater than or equal to the diameter of the fermenting reactor that are in inclined state. The inner part of the fermentation reactor is installed with multiple tangential plate (204), spiral combination plate (205), radial pole (202), stirring stick (203) and stirring shaft (201).    USE - Aerobic fermentation reactor.    ADVANTAGE - The aerobic fermentation reactor ensures reduced area for working with improved efficiency and eco-friendly manner.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for performing an aerobic fermentation, which involves:    (A) manufacturing design of inclined bottom air inlet type aerobic fermentation reactor, and then starting power supply through a power transmission device;    (B) adding pretreated organic waste and aerobic fungus through feed inlet using controlled conveying device, and then stirring them by using energy saving stirrer;    (C) performing aerobic fermentation of the obtained material, and then controlling waste gas through valve;    (D) controlling high pressure gas by using automatic closing high pressure gas source, and then controlling fermenting condition by automatic adjusting the controller according to feedback of oxygen content sensor;    (E) regulating heating temperature according to a feedback of circulation pump and a boiler temperature sensor;    (F) setting time of fermentation, and then opening a discharge valve after completion of fermentation; and    (G) repeating all the above steps for biological fermenting and degrading organic waste to obtain the finished product.
