Abstract

Research of design of solar dryer with evacuated tube collector for drying coffee bean has been done. This research is done through the stage of formulation, design, circuit and testing tools using coffee as material to be dried.Test results of a solar dryer designed then is being used for drying coffee bean (moisture content  from 52.80% to 12.30%), with forced convection system which the air speed are varied of 2-6 m/sec. During the drying process, the average weather conditions are in the range 143-855 Watt / m2, ambient temperature of 28-36 °C. The air temperature in the collector are 85-192 °C and the temperature in the drying chamber are 35-78 °C. The results showed that air drying velocity is directly proportional to the drying rate and collector efficiency but inversely to drying time and specific energy consumption (SEC).

Abstract

AbstractIt was conducted to engineering the adsorption column by using ferro powder waste as adsorbent to removal the H2S content of biogas from Palm Oil Mill Effluent. The first step it was conducted to calculated the adsorption column as purification column by character Palm Oil Mill Effluent (POME) considering. Further, is was conducted to annealed the ferro powder from industrial waste workshop in north Sumatera. Thus, it was conducted to annealed with temperature variation (800°C, 900°C and 1000°C) and the thick adsorbent (1 cm, 2 cm).The  result shows that  each adsorbent product is tested by applied of using direct that  puts in the  adsorbent  column. Applied research is conducted by flowing biogas trought column that the adsorbent is alreadyin the column. Temperature condition and the width of adsorbent was effecting of adsorption the H2S biogas and the optimal condition are 1000°C temperature and 2 cm of width adsorbance
