Semi-solid material quick drying system

Abstract

The invention belongs to the technical field of energy conservation and environmental protection, and particularly relates to a system for rapidly drying a semi-solid material. Comprising a shaftless double-screw conveyor, a material distributing machine, a forming machine, a drying machine, a chain conveyor, a cyclone separator and a waste gas fan, and the material distributing machine and the forming machine are of an integrated machine type; a preheating roller and a drying roller are arranged in the drying machine, and a separating knife is correspondingly arranged on the outer side wall of the corresponding drying roller above a lower outlet of the drying machine; a top air outlet of the drying machine is communicated with an inlet of the cyclone separator through a pipeline, a top air outlet of the cyclone separator is communicated with an air inlet of the waste gas fan through a pipeline, and semi-solid materials are conveyed to an inlet of the material distributing machine and mixed and stirred through the pair of stirring shafts to form particle materials. Particle materials are subjected to three-time extrusion forming through a pair of first rollers, a pair of second rollers and a pair of third rollers to form sheet-shaped materials, the sheet-shaped materials are preheated and dried at high temperature, dried particle materials are obtained through a separation knife, and the humidity of the dried particle materials is smaller than or equal to 30%.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a system for rapid drying of semi-solid materials. Background technique [0002] With the rapid development of modern industry and agriculture and the acceleration of urbanization, human beings are increasingly aware of energy conservation and environmental protection. Material drying has become an indispensable and important part of the industrial and agricultural process, especially the requirements for semi-solid materials are more prominent. At present, for the drying of semi-solid materials, due to the large heat transfer resistance, uneven drying, easy moisture return of materials, and low drying efficiency, it has become a technical difficulty in the drying process. The traditional process drying system has high energy consumption, low thermal efficiency, and high production and operation costs, which are not conducive to ene...
