Abstrak

The drying process is an important step in the postharvest handling of agricultural materials with the aim of preserving, reducing the volume and weight of the material. Farmers generally do the drying process by drying agricultural material directly in the sun. Drying in this way is very dependent on weather conditions, drying takes place relatively long, cleanliness is poorly maintained, drying quality is relatively uneven and requires a large area. Efforts to overcome these problems are by applying the artificial drying method. Drying air characteristics are needed for successful drying, namely high temperature, low relative humidity and high air velocity. To obtain these characteristics, various types of dryers have been engineered. This research is the development of solar collectors that can move to the position of the sun. The purpose of the research was to design a solar collector to move to the position of the sun, to prove the movement of solar collectors and the speed of fluid flow to the performance of solar collectors. The variables used in the study include solar radiation, ambient temperature, data collection time, speed of fluid flow at the outlet, movement of solar collectors, temperature in the solar collector and the temperature of the solar collector outlet. The speed of fluid flow varied into 3 treatments, while the movement of solar collectors varied by 2 treatments. Data collection starts from 8:00 a.m. to 4:00 p.m. with the interval of data collection is every 30 minutes. The results of the study show that there is an increase in the performance of solar collectors that move to the position of the sun rather than a silent solar collector of 13.7% in the space of the solar collector and 2.6% at the outlet of the solar collector. Keywords: dryer, solar collector, sun position
