Abstract

The roasting technique coffee bean was one of factor which influence quality powder coffee besides factor of raw material.   The roasting technique are include operator skill, mixing coffee bean in cylinder, air temperature in roasting’s cylinder,  heating source that is utilized, and activity after roasting.  The objective of this research is to make roasted machine of coffee bean with rotate mixer and test performance. Method is used by making roasted machine with cylinder made from stainless and rotate mixer from stainless strip spiral shape. In the top of cylinder fully equipped with covered and smokestack. Source of heat from elpiji stove.  The result of design was roasted machine coffee bean with dimension of length 92 cm, wide 62 cm and high 160 cm with ±40kg cylinder capacity.  Roasted machine component are beam, cylinder, mixer, side cover cylinder, inlet, outlet, top cover cylinder, anvil of stove and gearbox. Result of test showed that first test was 17,14  kg/jam capacity, second test was 24 kg/jam capacity and third test was 28.97 kg/jam capacity.  Rpm of mixer was 40 rpm and average fuel consumption 1.5 kg/jam. Keywords: roasted machine, spiral mixer

Abstract

Utilizing of biomass simple stove with high efisien intense be needed in order to be used widely society so far.  Chaff stove ussualy used is not perfectly is lack and necessary to make perfect.  Objective this research to modified  chaff stove and test performance by getting compare with before and after modified used different material. Method used by the way modified chaff stove now add material feeder, regulator flame and feeder flame.  The result indicate that the initial time light a fire until normally for chaff stove modified is longer than before modified, the end of temperature for chaff stove modified better than before modified, but chaff stove modified necessary increment with blower. On the use of coconut shell material, chaff stove modified more smoke because deficiency in oxygen, however use other material e.g chaff and sawdust is better. Keywords: chaff stove, modified
