摘要:

针对新疆传统摊晒杏干产品感官、卫生品质较低的普遍问题,利用新疆丰富的太阳能资源,研制出一种小型太阳能干燥(solar-drying,SD)装置,于2005~2008年连续4年在南疆三地州开展优质杏干的SD技术研究,通过装置热性能及产品质量的评比,提出一些简便实用的技术操作以指导实际生产。结果表明:该SD装置升温效果比较理想,温升与环境相比高出13℃,尤其下层温度可较纯温室提高8.3℃。无论天气晴阴,白天均能进行干燥,夜间防潮效果也较好。2008年SD杏干相对得率达5.19kg/m2,是传统露天摊晒的2.08倍,说明杏干的SD方式制干效率较高。优质杏干的SD工艺操作为每天10:00~19:00定时开启风机,在下雨前后需关闭风口和风机;倒盘在干燥前期(第1~3天)应放在正午14:00,以促进排湿;中后期为清晨10:00以前或傍晚20:00以后。

Abstract:

Due to poor sensory and hygienic quality of traditional dried-apricots in Xinjiang, a small-size solar-drying device (SD) with a greenhouse-like chamber that could exploit local abundant solar energy resource had been developed. Results indicated that SD had an excellent temperature-rising effect, which exhibited 13 ℃ of average temperature-rising effect and 8.3 ℃ of temperature-rising effect even in lower level of greenhouse chamber compared with the environment temperature. This solar-drying device had no limitations to weather conditions and also could provide a moisture-proofing function at night. The relative yield of apricot using this SD device was 5.19 kg/m2, which revealed 2.08 folds higher than the natural air-drying method. Therefore, SD technology can provide high-quality dried apricots due to its high efficiency. In order to obtain high-quality dried apricots, the optimal SD operation processes were investigated in this work.
