Fermentation process of fresh duck and goose manure

Organic fertilizer production process: A package of 'high temperature bacteria starter for poultry feces' is mixed with a small amount of corn flour and directly sprinkled into duck and goose feces for fermentation, each package can ferment 1 cubic meter; or a package of 'special high temperature bacteria starter for poultry manure' and corn flour can be directly used; or one package of this product can be mixed with brown sugar (white sugar and molasses can be used) and warm Water, made into a mixture of bacteria, fermentation 24 hours standby, we call the activated strain, can ferment 2-3 cubic meters.

The activated bacteria were layered or simply mixed into 2-3 cubic meters of duck and goose feces, and a small amount of bacteria mixture was left on the upper layer of the whole pile. Duck and goose manure with water content more than 80% will slow down the fermentation. Some auxiliary materials (hay, mushroom bran, straw, etc.) can be added. The moisture content of duck and goose manure after fermentation should be kept at about 65%, and the fermentation speed is the fastest.


The fermentation material pile is simply covered with thin film, which does not need to be sealed, and it should be protected from rain. Generally, the internal temperature can reach above 75, after 24 hours of fermentation, and the fermentation compost windrow turner turns the pile for 1-2 times or does not turn the pile (turning the pile will speed up the fermentation speed, and the quality is better). After the temperature is relatively constant, the fermentation is completed. The symbol of successful fermentation is: the material has completely no odor of feces, on the contrary, it has a light aroma after biological fermentation, and the pile is full of a large number of white hyphae.

There are two steps to process commercial organic fertilizer in the organic fertilizer production line: early fermentation and treatment part and deep processing granulation part. Organic fertilizer equipment needs fermentation compost windrow turner, crusher, mixer, organic fertilizer granulator, dryer, cooler, screening machine, coating machine, packaging machine, conveyor and other equipment.
