Observed YSD-UNIB12 Solar Drying Curve And Drying Time Prediction for White Pepper
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 12
Abstract
Drying is a determinant process to produce high quality white pepper. This study explored the utilization of the YSD-UNIB solar dryer to produce dry white pepper grains, aiming to determine the model of the curve of the relationship between moisture content and drying time, to predict the drying time to complete the drying process with respect to the placement of grains on the racks and the thickness of the grains layer, and to describe the resulting grains by using the Indonesian National Standard of white pepper. The results of the experiments showed that the drying air temperature was 12.15oC higher than the ambient air temperature, and the drying air relative humidity was 35.66% lower than the ambient air relative humidity. The solar drying process was 2.17 h faster than the sun drying. The average drying time varied from 12.8 h to 10.0 h from the lower rack to the upper rack, and varying the thickness of the grains layer from 2 cm to 8 cm the average drying time increased 8.7 h to 14.4 h. The dry pepper grains produced by the solar drying was qualified for Grade II but by sorting the unfilled out grains to meet the threshold of less than 1%, the grains from the 2 cm and 4 cm thickness of the grains layers were qualified for Grade I. The suggestion was made to employ the thickness of the grains layers of 4 cm and 8 cm in drying the white pepper for the world markets and the domestic markets respectively.
