The study, Development of Wood Vinegar Machine, aims to develop a Wood Vinegar
Machine that will make a wood vinegar in less tar that can use as an organic fertilizer and
pesticides. The machine is composed of two processes. The first process is the pyrolysis
process. This process is made up of a chamber with a length of 1 meter, 1.5 meters in height
and 1 meter of width. The kiln with a diameter of 0.6 meter absorbs heat when burning of
woods happens in the firewood storage. This process enables the extraction of wood which
produces smoke. The second process is the condensation process wherein the valve
actuator operates beyond 80 to 120 degrees Celsius upon collecting the smoke, while
condenser helps to condensate the passing vapour faster. Test results had shown that the
machine could produce a minimum of 200 ml wood vinegar within 3 to 4 hours. The use
of valve actuator decreases the tar content upon collecting the smoke beyond 80 to 120
degrees Celsius. The prototype is presented to thirty (30) evaluators to determine its
performance. The performance of machine is evaluated by 30 evaluators and obtained the
mean score of 4.53 which means Excellent. This concludes that the wood vinegar machine
had managed to increase the effectiveness of wood vinegar and the use of stainless steel
that have a high corrosion resistance which prevents contamination and improves the
quality of the machine.
