The schematic design of solar tunnel dryer is shown in fig 1: All dimensions in mm Fig. 1: Schematic diagram of solar tunnel dryer 2) Solar Tunnel Dryer with controlling circuit: The above solar tunnel dryers parameters are tested and controlled using arduino as shown below BLOCK DIAGRAM Fig. 2: Block diagram of solar tunnel dryer CIRCUITRY 1. In comparison to drying in the open, drying in the solar tunnel reduces drying time by about 60 percent. In addition, dried products retain their natural color and have a uniform look as well as texture that can help better market prices. Drying in the sun can turn agricultural products black but not when a solar tunnel is used. In addition, solar energy assisted tunnel dryers are extensively analyzed by some researchers. Large scale tunnel dryers were developed and analyzed for different scenarios [[60], [61], [62]]. Analyzing available solar tunnel dryers exhibited high potential of this type dryers that could be utilized for drying various products. Fact.MR reveals that the global solar dryer market will be valued at US$ 4.76 billion by 2032-end, expanding at a CAGR of 6.1% over the next ten years. Short Term (2022 Q2 to 2025): Augmenting utilization and integration of solar dryers in textile industry to positively market growth. Medium Term (2025-2028): East Asia and South Asia & Oceania Chaudhari AD, Salve PSP. 2014. A Review of Solar Dryer Technologies. International Journal of Research in Advent Technology. 2(2): 218-232.

Food Processing Technology. Operation. Load product (in aluminium trays)into the solar dryer. Check if temperature is within optimum drying range. Turn on electric fans (i.e. if temperature is above optimum drying range) Open vent to regulate air flow. Periodically check the products and internal temperature of the dryer to ensure effective drying of the products. vection dryers require a power source for operating an external fan or blower to create air current within the dryer. The forced con-vection types of dryers include; solar tunnel driers, greenhouse type solar driers, indirect forced convection solar driers and roof integrated solar driers [13,14]. The solar air collector cum drying chamber of solar tunnel dryer consists of 18 m length and 3.75 m width for drying 5000 coconuts per batch. Schematic diagram of PHD [35] .
