Fermentation and granulation processes in fertilizer production lines
2023/07/21
The characteristics of fermentation process can be summarized as follows: Fertilizer production process attaches great importance to the pretreatment of organic raw materials before fermentation. The fermentation conditions of water, carbon nitrogen ratio and porosity were optimized after the raw materials and auxiliary materials were automatically weighed, tempered and mixed by the premixed conditioner;
The fermentation equipment adopts the original solar composting environment control technology. The fermentation workshop has excellent warming and heat preservation effects and control functions. The compost fermentation will not be affected by bad weather such as strong wind, rain and snow any more, which improves the fermentation environment in winter and realizes annual all-weather production;
The optimal combination of dynamic agitation and static aeration system of fermentation compost windrow turner. To realize the "four in one" balance of solar energy, biological energy, mechanical energy and wind energy to balance the overall fermentation temperature and material water evaporation, which is conducive to the complete maturity of composting materials and rapid reduction of water content.
The characteristics of granulation process can be summarized as follows:
The layout of granulation process adopts modular combination, one line multi-function, flexible production adjustment. According to the market demand, the product direction can be adjusted in time. It can produce not only the series of powdery organic fertilizer, but also the series of granular organic fertilizer and organic-inorganic compound fertilizer;
The pelletizing process adopts the extrusion pelletizing technology suitable for organic materials. The advantages of the organic fertilizer granulator are: it is suitable for both organic materials and organic-inorganic mixed materials. There is no need to add water and binder to granulate, and the raw materials do not need to be crushed too finely. It can save water and electricity, and the particle forming rate is more than 93%.
The organic fertilizer granulator has compact layout and smooth production connection. On the basis of speed control and uniform feeding, the one-stop operation of continuous grinding, continuous batching, continuous granulation, continuous drying and cooling, and continuous screening and packing is realized, which breaks through the "bottleneck" of traditional organic fertilizer production efficiency underground and reduces the system energy consumption.
The whole organic fertilizer production line has high degree of automation control, improved production environment, fewer workers and low labor intensity.
