The manufacturing of NPK fertilizer is mainly the mixing of different chemical fertilizer raw materials, and the most important step in the process of producing organic fertilizer from livestock manure is composting and fermentation. Nowadays, with the development of Industrial Science and technology, fertilizer plants often choose compost turner to replace labor.
The organic fertilizer production line adopts compost turner equipment, which has larger production capacity, lower production cost and guaranteed fertilizer quality. So how do these turner machines carry out composting and fermentation?

Corn flour can be added into the fermentation products to increase sugar content for the fermentation of bacteria, so that the multi-dimensional complex enzyme bacteria quickly take the advantage. The stirred ingredients are piled into long piles with a width of 1.5m-2m and a bottom of 0.8m-1m, covered with sacks for aerobic fermentation. Then feed the mixed material into the mixer for mixing. The mixing must be even and thorough, and there is no dead block left. Then add the corn flour war fungus. As usual, 45% dew is required for fermentation, that is, the feet are pinched into a ball, and there is water between the fingers, but there is no dripping water. It can be collected as soon as you let go. The windrow turner machine regularly stirs the fermented product. This fermentation method is more suitable for individuals or small businesses. In the processing of organic fertilizer, the trough compost turning machine is more widely used.Trough compost turning machine
In terms of the fermentation process, the temperature on the first day of composting can reach 60 degrees Celsius to 80 degrees Celsius, which can kill E. coli, insect eggs and other pests; the second day eliminates the smell of chicken manure; the third day compost becomes loose, dry and less Modest red mycelium; on the fourth day, a kind of koji fragrance is recovered; on the fifth day, the bacterial fertilizer will be fermented and mature, and the bag can be unpacked and shipped out of the factory after a little reduction and drying. It is heated in one day, odorless in two days, loose in three days, fragrant in four days, and fertilizer in five days. The organic matter content of the green ecological organic fertilizer is above 45%, which is a kind of organic fertilizer with comprehensive nutrients.
