The main equipment for the production of organic fertilizer fermentation, the fermentation of geosyncline or pool type

structure, can be designed into a multi slot form, greatly reducing the equipment investment.  Turning work can be

divided into the spiral stirring cage and two drum type, with high bulk materials, plant covers an area of small, low

fermentation cost, turning completely without dead angle, fully fermenting etc.. Turning machine in the forward or

backward at the same time, by rotating the spiral body, let the organic material from the bottom up lifting, turning

back, to exchange oxygen, temperature, water vapor effect.
