Abstract

In this study, the performance of the evaporator system at the Department of Chemical Engineering, College of Engineering and Agro-Industrial Technology, University of the Philippines Los Baños was evaluated under varying steam flow rate, cooling water flow rate and juice age during May and June 2012. From the results, it was determined that the system was able to produce syrup with a concentration of 60 brix under a continuously recycling operation with a percent evaporation of 83.33% for almost all of the runs. Theoretical steam economy and heat transfer efficiency was at around 90% while actual values obtained were on a wide range, from around 30-70%. For the experimental time, the fastest that was obtained was 100 minutes, on the high steam flow rate setting and the slowest was 210 minutes on the base cooling water flow rate. The experimental time was determined to be de3creasing as the steam flow rate was increased. For the experimental time on varying cooling water flow rates, it was expected to decrease as flow rate increased but results showed deviations for the base rate. The experimental time on varying juice age was the same as expected.
