Arjoo et al., (2017) reported that the overall system efficiency of the solar tunnel chili pepper dryer was 17.63% and it took about 7 day. Ragul Kumar et al., (2020) also reported that overall drying efficiency of solar tunnel chili dryer was 16.25% and it took about 55 h while open sun drying took about 124 h. 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 Experimental study on a solar tunnel heat pump dryer for cocoa beans. M. Yahya. Agricultural and Food Sciences. 2016. A solar tunnel heat pump dryer was designed, constructed and tested for drying cocoa beans. The dryer consists of heat pump, single pass flat plate solar collector with fin, drying tunnel, turbine….

CrossRef Google Scholar A natural convection solar tunnel dryer comprising three major units, a solar collector unit, a drying unit, and a vertical bare flat-plate chimney, was constructed. No-load tests with a horizontal configuration of air entry into the collector resulted in a bidirectional air flow in the dryer. To correct this undesirable situation, an air guide at the collector was incorporated to ensure that the solar tunnel dryer and to design a controlling circuit to control various drying parameters inside it. 1) Solar Tunnel Dryer: The material used for construction of folding type small size passive solar tunnel dryer is given in the following table 1: Table 1: Material required for solar tunnel dryer Sr. No. Item Specification/ Quantity 1. xs2a1.
