不均匀干燥是传统多托盘干燥机的主要缺点。因此,提出了一种改进的具有和不具有集成显热存储(SHS)的主动式太阳能干燥机。这种干燥机的一个独特的特点是它的可移动的壁从干燥机的侧面将其转换为间接或混合模式,并在必要时。藤黄(GP)是印度东北部的当地季节性药用水果。GP的干燥动力学,在没有SHS的间接太阳能干燥机中评估了干燥机的干燥机性能和经济性分析(Exp。I),无SHS的混合模式太阳能干燥机(实验。II),带SHS的间接太阳能干燥机(实验。III),带SHS的混合模式太阳能干燥机(实验。IV),和开放式晒干(OSD)。干燥机的平均效率为18.12%,22.37%,21.74%,和24.46%的经验。I,Exp.II,Exp.III,和Exp。IV,分别。GP的水分含量从87.99%(w.b.)降低至12.09%(湿基(w.b.))。Exp的总干燥时间。I,Exp.II,OSD,Exp.III和Exp。静脉分别为31、26、53、28和10小时,分别。从11种干燥模型中,两期限模型是Exp的最佳拟合模型。I,Exp.II,OSD和Exp。III,米迪利和库库克模型是为Exp设计的。IV.最终产品的香味和颜色对Exp更好。IV.为Exp开发此干燥机。I,Exp.II,Exp.III和Exp。IV,所需价格约为25,000、27,000、26,000和28,000卢比(1美元=74.57卢比),分别,虽然经济回收期为1.6年,0.9年,1.4年,0.59年,分别。
Uneven drying is the key drawback of a conventional multi-tray dryer. Therefore, an improved active solar dryer with and without integrated sensible heat storage (SHS) was proposed. A unique feature of this dryer is its movable walls from the sides of the dryer to transform it to an indirect or mixed-mode as and when necessary.
Garcinia Pedunculata (GP) is a local seasonal medicinal fruit in Northeast India. Drying kinetics of GP, the dryer performance and economic analysis of dryer were evaluated in the indirect solar dryer without SHS (Exp. I), mixed-mode solar dryer without SHS (Exp. II), indirect solar dryer with SHS (Exp. III), mixed-mode solar dryer with SHS (Exp. IV), and open sun drying (OSD). The dryer\'s average efficiencies were 18.12%, 22.37%, 21.74%, and 24.46% for Exp. I, Exp. II, Exp. III, and Exp. IV, respectively. The moisture content of GP was reduced to 12.09% in wet basis (w.b.) from 87.99% (w.b.). The overall drying time for Exp. I, Exp. II, OSD, Exp. III and Exp. IV were 31, 26, 53, 28, and 10 h, respectively. From the eleven drying models, the Two-Term model was the best-fitted model for Exp. I, Exp. II, OSD and Exp. III, and Midilli and Kucuk model was for Exp. IV. The final product\'s fragrance and colour are better for Exp. IV. Developing this dryer for Exp. I, Exp. II, Exp. III and Exp. IV, the price required was around 25,000, 27,000, 26,000, and 28,000 INR (1 US$ = 74.57 INR), respectively, while the economic payback periods are 1.6 years, 0.9 year, 1.4 years, and 0.59 year, respectively.
