Abstract: This study done for designing industrial solar air heater drying unit with tow part of experimental steps(selecting solar air hater type and other par for controlling outlet temperature through mixing hot and ambient air through static mixture) ., The experiment done for 6 six days for each type using fabricated glass covered corrugated solar air heater with tow possibility of modifications one of them with fixed absorber plate defined as type one and other one tested with removed absorber plate which defined as type two experiments done with full accessory (air supply fans, temperature mea with same test study using device, fresh air motor controlling RPM and fabricated static mixture. The drying temperature range (45 C to 55 C).Before testing pilot unit calculation of predicted hot air temperature was done for validity of unit then the experiments has been made with pilot unit of solar air heater with fresh air steam and static condition, the result show that solar air heater type one is better for stable results for out let temperature and suitable for working. also the experiments show that, the presented value of temperature of hot mixed air of SAH type one have fitness with set point of controller 90% for day one and day two but for SAH type two the present value haven’t fitness with set point, the reading either high or low than the set temperature , for the other part of study prove that mixing hot air from solar air heater and fresh ambient air is success and control system working properly for the propellant drying process.
