太阳能和蒸汽源红外中草药干燥装置实验研究

Experimental Study of Solar Energy and Steam-Heat Far-Infrared Cabin for Drying Chinese Medicinal Herbs

本文叙述了一种将太阳能干燥技术、远红外加热技术与蒸气采暖技术结合为一体的新型综合干燥装置。就其设计原理、基本构思以及有关设计参数的选定,进行了论述与计算。并对淮山、杏仁、当归等7种中草药红外吸收光谱曲线进行了测试,给出了它们与该装置所用的低温远红外涂料的发射光谱曲线的匹配情况。文中还给出了利用太阳能干燥装置对几种中草药进行干燥加工试验的结果。

This paper describes a new comprehensive drying cabin which combines the techniques of solar energy drying, far-infrared heating and steam-heating. It discusses the basic conception, the designing principles and the selection of designing parameters and presents calculations of the design. In this paper, we present tests on the infrared spectrum absorption curves of 7 kinds of Chinese medicinal herbs, such as huaishan, apricot seeds, angelica roots etc and the matching between these absorption curves and the cabin's radiation spectrum curves of low-heat far-infrared paint. Meanwhile, this paper also gives the experimental results of drying some chinese medicinal herbs by using the solar energy drying cabin.
