Abstract

This study introduces the development and analysis of an innovative solar rotary dryer assisted with phase change materials (PCM) and air recycling mechanism with desiccant materials. The aim purpose of this paper is to find the optimal conditions for the parameters during the drying process by considering the uniformity of the airflow distribution in the

zone in the rotary solar dryer. The performance of the rotary solar dryer system for airflow velocity and rotation speed at three levels and the thermal storage system (TES) with and without PCM. Three levels of airflow rate (2.5,3.5 and 4.5 m/s) and drum rotational speec (0.1, 0.3 and 0.5 rpm) were considered for the test. An

model used to generate various fuzzy rules defined from the input-

to make the analysis process faster. The results showed that the proposed fuzzy model can predict the performance of the proposed dryer with higher accuracy (RMSE < 0.0134, R² > 0.9). In addition, life cycle assessment was conducted using ReCipe-2016 to investigate and quantify the effect of different environmental parameters and materials during drying process of grape samples. PCM and recycling mechanism are used to enhance the performance of the designed rotary dewatering system. In addition, the LCA impact findings showed that the use of PCM leads to a reduction in environmental pollutant emissions of at least 9.7 % and at least 21.25 % relative to the system that uses electrical energy to feed the rotary dryer. By considering the findings, it can be stated that the proposed system can be used as a sustainable and scalable solution for agricultural applications.

一种新型相变材料和干燥剂太阳能旋转干燥机的性能和LCA评价

本文介绍了一种新型的太阳能旋转干燥机的开发和分析，该干燥机辅助相变材料（PCM）和干燥剂材料的空气循环机制。本文的目的是考虑旋转太阳能干燥机传热传质区气流分布的均匀性，找出干燥过程中各参数的最佳条件。研究了旋转太阳能干燥机系统在风速和转速三个水平下的性能，以及蓄热系统（TES）在有和没有PCM的情况下的性能。试验考虑了三种风速水平（2.5、3.5和4.5 m/s）和转鼓转速（0.1、0.3和0.5 rpm）。采用自适应模糊模型对系统的输入和输出变量之间的关系进行建模，从而得到系统的最优条件。一种sugno - typefuzzyference模型，用于根据输入-输出数据集生成各种模糊规则，使分析过程更快。结果表明，所提出的模糊模型能较好地预测所提出的干燥机的性能(RMSE <；0.0134, R2 >；0.9)。此外，利用ReCipe-2016进行生命周期评价，考察和量化不同环境参数和物料对葡萄样品干燥过程的影响。采用PCM和循环机构提高了所设计的旋转脱水系统的性能。此外，LCA的影响结果表明，相对于使用电能给旋转干燥机供电的系统，使用PCM可减少至少9.7%和21.25%的环境污染物排放。考虑到研究结果，可以表明所提出的系统可以作为农业应用的可持续和可扩展的解决方案。
