摘要
针对海带烘干时间长、效果差的问题,依据有限体积法,使用三维软件建立热泵型海带烘干室物理模型,采用数值模拟软件,对海带烘干室物料层中海带含水率进行模拟计算。选取不同干燥温度、风速、格栅间距进行单因素模拟研究,综合各因素影响,对海带含水率进行优化分析,确定在烘干温度为55℃、烘干气流速度为9 m/s、保持烘干室内格栅间距为0.16 m的条件下,海带烘干效果达到最优。此研究结果为海带干燥提供了一定的理论指导。
Aiming at the problem of long drying time and poor effect of kelp,according to the finite volume method,three-dimensional software was used to establish the physical model of heat pump-type kelp drying chamber,and numerical simulation software was used to simulate the kelp moisture content in the material layer of kelp drying chamber.Different drying temperatures,wind speed,grid spacing and other factors were selected to conduct a single-factor simulation study,and the moisture content of kelp was optimized and analyzed based on the comprehensive influence of all factors.It was determined that the drying effect of kelp was optimal under the conditions of 55℃drying temperature,9 m/s drying airflow velocity and 0.16 m grid spacing in the drying room.The results provide theoretical guidance for kelp drying.
