By using fresh chicken manure as a main fermentation raw material, the organic fertilizer fermentation method disclosed by the invention achieves the purposes of harmless treatment, recycling treatment and reducing treatment.

The invention discloses a stair-stepping tea continuous-fermentation device. The stair-stepping tea continuous-fermentation device at least comprises a fermentation group. The fermentation group comprises a frame and at least two fermentation units. The at least two fermentation units are stepwise arranged from top to bottom. Each one of the at least two fermentation units comprises a fermentation tank, a discharge device, a scattering device and a conveyer device. The fermentation tank is provided with an air chamber communicated with an inner cavity of the fermentation tank. A bottom cover is arranged at the bottom of the fermentation tank. The air chamber is annular. The top and the bottom of the air chamber are sealed. A side of the air chamber is provided with a ventilation pipe communicated with an external ventilation device. An atomizing nozzle is arranged in the ventilation pipe. A temperature sensor and an oxygen concentration sensor are arranged in the inner cavity of the fermentation tank. Through the fermentation tank having two or more layers and through a cycle flow of primary fermentation, scattering and secondary fermentation, fermentation is more uniform and thorough. Through the air chamber having an annular structure, air convection ventilation is formed in the air chamber so that uniform fermentation is realized. Uniformity and consistency of quality of black tea fermented by the stair-stepping tea continuous-fermentation device are guaranteed.
