The methods of livestock and poultry manure feed mainly include drying method, silage method and biological method. The main drying methods are: natural drying, high temperature drying and low temperature drying. Natural drying costs are low, but the drying time is too long and is easily affected by environmental factors such as weather; high temperature drying adopts high temperature quick drying.The drying machine is heated, the drying speed is fast, the sterilization effect is good, but the energy consumption is large;
The traditional granulation method is double roller granulator, including two kinds of roll granulation method and agglomeration method. Extrusion granulation is simple and practical. After fermented compost is adjusted to a moisture content of 20% to 30%, it can be directly entered into the granulator and extruded into cylindrical granules. For small plants with an annual output of less than 10,000 tons, disc granulation should be selected, and natural air drying can be used directly, without the need to configure drying equipment, equipment investment costs are low, and space is saved; organic fertilizer plants with an annual output of 10,000 tons should choose rotary drum granulator, the granulator is equipped with rotary drum drying equipment, which has large production capacity and good granulation effect.
Using the npk fertilizer production line, firstly, the bacteria and livestock and poultry manure are fully stirred by the method of stirring, so that the microbial bacteria can be integrated into the livestock and poultry manure. Type mixers, granulators, dryers, coolers, drum screening machines, coating machines, packaging equipment, belt conveyors and other equipment are then subjected to a series of harmless treatments such as rapid heating, fermentation, decomposing, and deodorization. manufactured organic fertilizer.
