新型太阳能驱动的相变材料与干燥剂系统结合的旋转干燥机性能及生命周期评估

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 h e a t a n d m a s s t r a n s f e r 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 a d a p t i i v e n e u r o - f u z z y model used to model the relationships between the input and output variables of the system and to obtain the optimal conditions. A S u g n o - t y p e f u z z y i n f e r e n c e model used to generate various fuzzy rules defined from the input- o u t p u t d a t a - s e t 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, R 2 > 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.
