Abstract

Evaluation of solar dryer performance is an essential step in the selection process of the most efficient and effective solar dryer design for a particular application of solar drying. The evaluation of solar dryer performance can be carried out in various ways and there are no standardised performance evaluation procedures available for the solar dryers. This paper describes the application of an evaluation procedure of solar dryer performance, which is based on the procedure that was initially developed by Leon et al. (2002) and arguably one of the most reliable among existing ones. The procedure was validated by the use of a scaled down solar tunnel dryer model. The solar tunnel dryer was tested alongside with open sun dryer as a control measure on drying wet cassava grates. Tested parameters of dryer were based on the dryer's physical feature, thermal performance and cost analysis. The test results confirm the reliability of the procedure used to evaluate performance of the scaled down model of the dryer. Therefore, the procedure of performance evaluation demonstrated is recommended for application in similar situations.

自然对流混合模式太阳能干燥机的可靠性能评价程序

对太阳能干燥机性能的评价是为太阳能干燥的特定应用选择最高效和最有效的太阳能干燥机设计过程中必不可少的一步。太阳能烘干机性能的评估可以通过各种方式进行，目前还没有针对太阳能烘干机的标准化性能评估程序。本文描述了太阳能干燥机性能评估程序的应用，该程序基于Leon等人(2002)最初开发的程序，可以说是现有程序中最可靠的程序之一。该方法通过使用按比例缩小的太阳能隧道干燥器模型进行了验证。将太阳能隧道式干燥机与开放式太阳干燥机一起作为干燥湿木薯格栅的控制措施进行了试验。通过对干燥机的物理特性、热工性能和成本分析，确定了干燥机的试验参数。测试结果证实了用于评估干燥机按比例缩小模型性能的程序的可靠性。因此，建议在类似情况下应用所演示的性能评估程序。

期刊介绍： Technology is an increasingly crucial input in the industrialisation and development of nations and communities, particularly in the current era of globalisation, trade liberalisation and emphasis on competitiveness. The shared technologies and innovations of today are giving birth to the radically different agrifood industries and communities of tomorrow. There is mounting evidence that investments in postharvest research and infrastructure yield high rates of return that are comparable and often higher than investments in on-farm production alone.
