Does dried chicken manure and cow manure need to be fermented?

Sun-dried chicken manure and cow manure need to be fermented. The fermented chicken manure and cow manure belong to the category of farmyard manure. Fermentation is a key step in the production of organic fertilizer. The purpose is to deodorize, sterilize, and increase beneficial bacteria. Unfermented raw materials contain heavy metals, insect eggs, weed seeds, and other harmful bacteria. If directly applied, it will not only consume fertilizers but also increase the probability of crop diseases and insect pests.

The method of fermenting chicken manure and cow manure in a large-scale organic fertilizer processing plant:

There are three common fermentation methods: fermentation tank fermentation, strip fermentation, and tank fermentation.

Fermentation tank fermentation is the use of a new type of fermentation equipment, the raw materials are put into the fermentation tank for fermentation, the equipment has a deodorization system, a ventilation system, a stirring system, and an auxiliary heating system. The characteristic is that it is not affected by the environmental temperature, can be produced at any time, and the fermentation speed is fast.

Fermentation in a pile, using an open field for fermentation, is suitable for organic fertilizer processing plants where the site is limited and does not want to invest heavily in civil engineering. The characteristic is that the operation of the fermentation site is flexible and changeable, and the self-propelled stacker is easy to walk.

Trough type fermentation, the fermentation tank is built in the plant area, the upper end of the fermentation tank wall is installed with a track, the trough type turning and throwing machine walks on the track, the raw materials are put into the tank, and the turning machine moves back and forth to turn and throw the materials. The characteristic is that the equipment is stable. It is suitable for organic fertilizer processing plants with larger output and batch production.
