Fuente: WIPO "processing tomato" The invention provides a dryer for tomato planting fertilizer processing and a planting fertilizer drying method.The dryer comprises a machine base, a barrel is rotatably installed in the machine base, a plurality of shoveling plates are fixedly installed on the inner wall of the barrel and distributed in a circumferential array with the barrel as the center, and side plates are fixedly installed at the two ends of each shoveling plate; two symmetrically-distributed extension plates are arranged in the two side plates, when the water content of materials changes, the stir-frying height of the materials is adjusted by correspondingly adjusting the inclination angles of the extension plates, when the humidity of the materials is large, the included angles formed by the extension plates and the shoveling plates are kept in the minimum state, and at the moment, the materials start to slide off at the highest position; when the humidity of the materials is small, the included angle between the extending plate and the shoveling plate is increased, the stir-frying height of the materials is reduced, energy consumption and production cost can be saved, and meanwhile it is guaranteed that the expected drying effect is achieved.
