Solar powered tunnel dryer can be an answer to this problem. It is a cost-effective solution to the growing demand for renewable energy. It saves on water consumption and provides thermal comfort during summer periods. The solar tunnel dryer is a device that can be used to dry agricultural produce which includes fruits, vegetables, and grains. The cross sectional area of the solar tunnel dryer was trapezoidal in shape having 0.254 m 2 face area, with length and width of three meters and one meter respectively. It comprises a collector section (1.35 m) long and a drying section (1.65 m long) and two PV powered DC fans to provide the required air flow rate over the perishable Solar PV powered mixed-mode tunnel dryer for drying potato chips, Renewable Energy (2017), doi: 10.1016/j.renene.2017.10.007 This is a PDF file of an unedited manuscript that has been accepted for This paper presents the thermal modelling and experimental validation of a walk-in type solar tunnel dryer for drying of fenugreek leaves in Indian climatic conditions. The tunnel dryer is a metallic framed structure covered with a 200-μm ultraviolet stabilized plastic sheet. This dryer has a 5 × 3.75-m floor area and is 1.75 m in height. Its loading capacity of leafy vegetables is about 100 gradual reduction in price of solar collector s coupled with the increasing A solar tunnel dryer with 122.95 m2 solar collector area was sufficient for drying handmade paper from 53.85% to 9. An indirect two-stage solar tunnel dryer has been developed to study the drying characteristics of two chili pepper varieties. The effect of chili layer density on the drying time and moisture .
