Drying Technology and Demand for Chicken Manure Drying

Large and medium-sized chicken farms or developing regional large-scale chicken production must have the supporting chicken manure harmless treatment facilities and make the emission standards for various pollutants in the farm. The best way until now is drying. The government should raise the awareness of the importance of the non-destructive treatment of chicken manure of the breeders and related departments.

The waste gas and dust produced during the drying of chicken manure can easily cause secondary pollution. At present, the solution to this problem in a larger chicken manure factory is that the exhaust gas is piped into a pool of dilute sodium hydroxide or dilute sulfuric acid so that the dust and harmful gases in the waste gas are absorbed; After the adsorption with activated carbon, about 75% of the harmful gas and dust in the exhaust gas after two absorption are adsorbed, and the emission of the exhaust gas is obviously improved. The other way is setting up a secondary combustion device so that the exhaust gas can be further burned to remove the stink. or you can also consider adding a moderate amount of formalin to it before the manure is processed, so that it can be combined with ammonia.

The continuity of chicken manure production and the use of fertilizer have the seasonal contradictions. The production of agriculture is obviously seasonal. In fertilizer-using peak season, the supply of dried chicken manure can not adequate to the demand, and even wet chicken manure can be quickly bought at a higher price. However, in the off-season, the chicken manure in the chicken farm often backlogs, and even though the price is very low, no one wants them. In this way, the production of chicken manure has obvious seasonality. During the period of one year, the equipment of chicken manure has been idle for several months and the processing cost has increased. Therefore, it is necessary to build a large manure field (slot) in the chicken manure processing plant. The bottom of Manure field (slot) should be hardened, with low wall in the the surrounding edge, plastic sheeting at the top, which can prevent This prevents the chicken manure wastewater from seeping into the groundwater and also can prevent the rain manure from polluting the environment. At the same time, in the plastic shed, the heating of chicken manure can also be dried, reducing the burden for subsequent drying. during the off-season, the cheap chicken manure collected in the chicken plant can be collected in the storage slot, and the regular processing can effectively reduce the purchase cost of wet chicken manure.

High water content of chicken manure can affect the processing benefits, that is, high moisture content of wet chicken manure increases the processing cost of dried chicken manure. The moisture content of chicken manure in general season is about 70%, while in summer, it can be more than 80%. Such high moisture content is not conducive to the drying of chicken manure, which needs to be pretreated before drying, reducing the moisture content of chicken manure to about 60%. Besides, the chicken plant owners should further expand the application of dried chicken manure. Of course, currently, the dried chicken manure after the dryer is mainly used as fertilizer.
