Automatic Thermal-Controlled Dryer Machine Integrated with Uninterruptible Power Supply for Commercial Carrot Snack Production

In response to the growing demand for efficient local food preservation technologies, an automatic thermalcontrolled drying machine integrated with an Uninterruptible Power Supply (UPS) was developed to improve the production quality of commercial dried carrot snacks in Cavite City. This study focuses on the development of a prototype that automates flavor application, regulates drying temperature, stabilizes moisture removal, and sustains operation during power interruptions. Utilizing a qualitative development research design, the study involved iterative prototyping, observational assessments, and expert evaluation to refine the machine’s features and determine its practical applicability in small-scale food processing. A qualitative development research design to develop and assess a thermal-controlled drying system for the nutrient preservation of carrot snack chips. . The effectiveness of the system will be assessed using observational data as well as semi-structured interviews with a few specific users which are vegetable sellers and consumers in Cavite City, Cavite. Initial data was collected through interviews conducted by the researchers in Cavite City where vegetable vendors and consumers routinely buy and/or sell fresh carrots. In order to assess current issues in postharvest carrot handling, a preliminary interview took place with 28 respondents, consisting of vendors/consumers in Cavite City. The findings revealed that the prototype effectively minimized spoilage, with an average rate of 7.1%, and maintained moisture content at 13.6%, which is within the acceptable standard (≤15%). The drying process preserved such as color, texture, flavor, and aroma, indicating good nutrient retention. Additionally, the integrated UPS ensured continuous and stable operation during power interruptions, improving overall efficiency and reliability. These results confirm that the prototype enhances shelf life, reduces losses, and demonstrates strong potential for practical and commercial application. In response to the increasing demand for efficient agricultural processing technologies in the Philippines, several challenges continue to affect the quality, consistency, and shelf life of dried food products such as baby carrot snacks. Findings from this research indicate that incorporating temperature control with uninterruptible power sources increases drying reliability, particularly in regions with fluctuating power. Automating various aspects of the production process supports improved efficiency and decreased reliance on human input, improving the consistency of produced goods.
