Research on Structure Design and Simulation Test of Double-Layer Chain Plate Shared Dryer

Abstract

In order to reduce the fuel consumption rate of the traditional belt drying device and improve the utilization rate of the internal space of the drying equipment, a double-layer chain plate shared drying device is designed in this paper. The device adopts the chain plate transmission mode, which can simultaneously make use of the upper and lower chain plates of a transmission chain, and adopts the drying mode of combined heat source. Based on the gas-solid heat transfer theory, a numerical simulation model of the internal chamber of the dryer was established, and the temperature field variation of the hot air on the conveyor chain plate of the dryer was analyzed. Through numerical simulation analysis, the results show that the temperature field inside the oven is evenly distributed, and the temperature difference between the boundary and the internal temperature of the conveyor chain plate is small. Combined with the comparative analysis of chili drying process curve, it is verified that the drying device can effectively control the change of its internal temperature curve, and improve the drying efficiency and space utilization of the dryer. The research results of this paper will lay a theoretical foundation for the industrial application of the double-layer chain plate shared dryer.
