Renewable energy sources such as solar energy for drying purposes in a more effective and efficient way is inevitable for preservation of agricultural products in developing nations with inadequate access to electricity. This study investigates the effects of using a solar tracking device on the energy performance of drying processes. Three categories of drying conditions were carried out simultaneously; for a fixed solar box dryer, a solar box dryer aided by a tracking device, and open air drying over an effective total drying time of 6 hours each day, for 5 days.

“…The indirect dryer presents many advantages in term of products quality and possibility of controlling the parameters of the system (Figure 1) (Tchaya et al, 2014). Pirasteh et al (2014) showed the importance of solar drying application. An important review regarding the various details such as design, construction and operational principles of practical solar dryers is reported by Ekechukwu and Norton (1999).…”

Solar drying is used to reduce post-harvest losses. An indirect solar dryer with oriented air is presented. It provides the ability to store energy. This work predicts the outlet temperature at the collector in the single-face and bifacial modes of collector. The heat balance applied to each element is determined taking into account the temporal term which characterises storage in the material. The simulation is done using Matlab software. Both models of the collector are validated by comparing the experimental and theoretical curves. The results show that the two curves of outlet temperatures have the same profile when the global heat transfer coefficient loss is 2.94 W.m -2 .K -1 , the contact resistance between the absorber and the insulator is 0.025 W -1 .m2.K and the velocity is 0.2 m.s -1 . The contact resistance has a significant influence on the outlet air temperature but not accessible for controlling temperature compared to the velocity. G.B.

Abstract-The energy consumption of dryers as an energy-intensive industry system is discussed in the present paper. In order to reduce this energy amount, solar dryers were applied since ancient times, among these kinds of dryers, high drying rate solar dryers include fluidized bed and spouted bed were discussed in this research study. The experiment and calculation results depicted that, the fluidized bed solar dryer has higher drying rate than spouted bed dryer, even though, spouted bed dryer has less energy intensity consumption.Index Terms-Energy efficiency, fluidized bed, solar dryer, spouted bed.
