Description

Drying device for granular materials Technical Field The utility model relates to the technical field of material drying, in particular to a drying device for granular materials. Background In order to realize effective drying, the existing particulate material generally adopts hot air as a heat source, and removes moisture in the material through heat exchange between the hot air and the material, thereby achieving the purpose of drying. At present, when hot air is in contact with stacked granular materials, since the surfaces of the materials are directly exposed to the hot air, the granular materials on the outer surfaces of the materials can quickly absorb heat and evaporate water, so that the materials are easy to dry excessively, and the excessive drying can not only lead to surface hardening and cracking of the materials, but also influence the subsequent processing and using performance of the materials. Meanwhile, because hot air is difficult to penetrate through the interior of the material pile, the heat received by the interior particles is limited, and the water evaporation speed is low, so that the condition that the interior particles are not completely dried possibly occurs, and the quality of the particle materials is reduced. The prior Chinese patent publication No. CN2786517Y is a granular material drying device, which comprises a closed heating chamber and a roller driven by a driving device to rotate, wherein materials roll continuously along with the rotation of the roller in the drying process, heat generated by a far infrared heating element is directly applied to the materials in the roller, the materials are heated uniformly, negative pressure is formed in the heating chamber under the action of an air extractor, moisture generated in the drying process can be discharged from the heating chamber efficiently, the heat efficiency is high, the drying device is suitable for drying granular materials, and is also suitable for coating and dampproof treatment of granular materials, pills and tablet medicines, but the uniform drying of the granular materials in the roller can lead the heated of the individual granular materials to be uneven and not thorough, thereby reducing the quality of the granular materials.
