Özet
It was aimed to dry a by-product of tomato paste production (tomato pomace) by minimizing the losses valuable components and reducing energy consumption. In this concept, a daylight simulated photovoltaic-assisted dryer (DPVD) applying the daylight in different modes and intensities during drying was custom-designed. The effects of daylight applications on the change of some quality characteristics of tomato pomace and system performance characteristics were investigated, and the optimum drying condition was determined. The process conditions included the combination of three different daylight application modes (UV-blocked daylight via solar tube-DLST, DLST + LED, and LED) and three different daylight intensities (2,500, 7,500, and 10,000 lux). The drying was applied for 240 min at constant air temperature (60 degrees C) with an air velocity of 2 m/s. The moisture content and the water activity values of dried tomato pomace were 8.86 +/- 2.00% and 0.57 +/- 0.10%, respectively. The lycopene and beta-carotene losses after drying were determined as 68.36 +/- 4.32% and 65.66 +/- 4.33%, respectively. The energy and exergy efficiencies of the system were in the range of 19.56%-35.73% and 5.10%-17.05%, respectively. The optimum condition meeting the criteria of superior quality and high-performance characteristics was obtained by applying DLST at 7,500 lux (desirability 0.728). In the performance improvement studies, it has been concluded that all the energy required for the process could have been fulfilled as 100% from solar energy with the support of photovoltaic panels. In other words, it was demonstrated that the developed DPVD system could be used to dry the tomato pomace not only in terms of providing high food quality and safety, but also in terms of having high energy efficiency.
