| Summary, etc. | ABSTRACT VALENZUELA, MAYROSE E. and GUDOY, NOLI ANGELO F., Mariano Marcos State University. May 2021. DEVELOPMENT OF A SOLAR ENERGY SYSTEM FOR DRYING. Major Adviser: Engr. Samuel S. Franco, MSAE. Open-air sun drying or direct and uncontrolled sun drying is still the most popular method of preservation and storage but leads to contamination, theft or damage, no protection from rain, dew or any storm that causes poor quality of the dried product. Drying involves heat and mass transfer and changes several parameters of the product such as volume, density, mass, moisture content, humidity inside, product size, chemical changes along with the product quality. Such disadvantages encouraged developers, innovators to make a closed solar dryer. Several types were developed which include solar-biomass hybrid solar dryers. Students of Jazan University also developed a solar dryer which uses temperature and humidity sensors. These inspired the authors of this paper to design and develop a Solar Dryer to solve the problem of quality caused by drying in an open environment. A closed chamber solar dryer which uses the roof of a building painted with black paint as a solar thermal collector and 12V DC fan that sucks the heated air to the drying chamber. A solar dryer provided with an alternative power supply that automatically works when the battery reaches 11.5 volts to prevent over-discharge. The results obtained during the test period revealed that the temperatures inside the dryer and solar collector were much higher than the ambient temperature during most hours of the day-light. And the black paint is concluded to have a great help in increasing the temperature. The heated air temperature that pumps inside the drying cabinet were up to 60-70 degrees Celsius for about three hours just before and after 12noon, depending on the weather condition. The dryer exhibited sufficient ability to dry food items rapidly to a safe moisture level, and it ensured a superior quality of the dried. |
