Abstract

The article outlines the relevance of production of dried products using a mobile solar dryer plant with mobile shelving. For intensification of the drying process, the convection of the drying agent flow in the proposed design of drying chamber was studied via numerical solution of the Navier–Stokes equations. As a result, a graphical interpretation of isolines of moving stream of drying agent in a chamber was obtained. Varying dimensionless parameters of the drying agent enabled complete coverage of all zones of the dryer chamber. The motion of shelves due to gravitational forces allowed uniform drying of materials. Through multivariate experiments, the influence of the temperature-time regimes of the dryer chamber on the particle size was investigated. The optimal drying conditions for cut fruit are presented.

在移动式搁架式太阳能干燥机中干燥蔬菜产品

摘要

本文概述了使用带有移动货架的移动太阳能干燥设备生产干燥产品的相关性。为了强化干燥过程，通过 Navier-Stokes 方程的数值解研究了干燥室设计中干燥剂流的对流。结果，获得了腔室中干燥剂移动流的等值线的图形解释。干燥剂的变化无量纲参数能够完全覆盖干燥室的所有区域。由于重力作用，搁板的运动可以使材料均匀干燥。通过多变量实验，研究了干燥室的温度-时间制度对粒度的影响。提出了切开水果的最佳干燥条件。
