Özet:

 In this study, modelling simulations were employed to analyze the effects of inlet drying air flow rate and temperature, product feed rate, and heat recovery ratio in a spray dryer. The energy efficiency, energy savings, and final product outlet temperature were investigated. As the heat recovery ratio by-pass ratio increased, total energy savings improved, though energy efficiency declined at a slower rate compared to energy savings. The modelling study, conducted with five different by-pass ratios 100, 70, 50, 30, and 0, indicated that the optimal by-pass ratio was 30. At this ratio, energy efficiency decreased by 5, while energy savings increased by approximately 16. Additionally, at higher by-pass ratios, the product outlet temperature rose significantly. To maintain product quality, it was found that the maximum acceptable temperature of 60C could be achieved at by-pass ratios of 40 or lower.
