摘要

本研究评估了由间接型邪恶热管支持的太阳能干燥器的性能。为了将热量从太阳能集热器传递到干燥室,开发了一种被动式高导热热管。下午 1:30 时,干燥室与环境空气的温差为 21 °C。结果表明,经过 12 小时的干燥,香蕉片的含水量从 150 % d.b. 降至 11 % d.b.:0.1452、0.1492 和 0.1613 千克水/千克干物质/小时。有效水分扩散率在 1×10-7 到 9.405×10-8 m2/s 之间,而露天日晒干燥的平均有效水分扩散率最低,为 3.87×10-07 m2/s。烘干机的效率估计为 26%。此外,开发的干燥机的投资回收期为 0.57 年。开发的烘干机可安装在任何农村,用于烘干任何农产品。

Experimental investigation of indirect solar dryer integrated with wicked heat pipe

In the present study, the performance of a solar dryer supported by an indirect type wicked heat pipe was assessed. To transfer the heat from the solar collector to the drying chamber, a passive high thermal conductivity heat pipe was developed. At 1:30 pm, there was a 21 °C temperature difference between the drying chamber and the ambient air. The results indicated that after 12 hours of drying, the banana slices’ moisture content dropped from 150 % d.b. to 11 % d.b. It is found that the average drying rates in Trays 1, 2, and 3 are the following: 0.1452, 0.1492, and 0.1613 kg water/kg dry matter/h. The effective moisture diffusivity ranged from 1×10−7 to 9.405×10−8 m2/s, whereas open sun drying had the lowest average effective moisture diffusivity of 3.87×10−07 m2/s. The estimated dryer efficiency was 26 %. Also the payback period of developed dryer was found to be 0.57 years. The developed dryer can be installed in any rural villages to dry any agricultural products.

期刊介绍: The aim of the Journal of Mechanical Science and Technology is to provide an international forum for the publication and dissemination of original work that contributes to the understanding of the main and related disciplines of mechanical engineering, either empirical or theoretical. The Journal covers the whole spectrum of mechanical engineering, which includes, but is not limited to, Materials and Design Engineering, Production Engineering and Fusion Technology, Dynamics, Vibration and Control, Thermal Engineering and Fluids Engineering. Manuscripts may fall into several categories including full articles, solicited reviews or commentary, and unsolicited reviews or commentary related to the core of mechanical engineering.
