FIELD: organic fertilizers. SUBSTANCE: method consists in that droppings are exposed to microwave electromagnetic field in a chamber with continuous displacement of fertilizer and simultaneous blowing with first flow of hot heat carrier. Before charging into chamber, moisture content in fresh droppings is lowered by means of mechanical dehydration to 50% and less, after which dehydrated material is granulated, granules are blown with flow of hot heat carrier and rolled in fine powder of ground dry fertilizer. EFFECT: increased partial drying velocity and increased productivity. 1 dwg |
