Abstract:
The purpose of this study was to determine the yield and quantity of liquid smoke
produced from modified equipment engineering and using palm fronds as fuel. The method used is
the yield calculation method and the calculation of the quantity of the tool. The process of
assembling and manufacturing liquid smoke, preparation of materials and tools that will be used to
make engineering smoke catchers and liquid smoke makers. Welding is done and assembled into
a single unit or according to the pattern. The length of time for welding and assembling the
pyrolysis tool is approximately 3 days, arrange the palm fronds that have been cut to the size of the
furnace neatly into the furnace, install bamboo with a length of 4-5 meters with a slope of 30-40°.
After the oil palm fronds have been arranged and the bamboo has been installed, pour the
kerosene into the kiln that has been arranged with the palm fronds and then burn it. After the midrib
burns and emits black smoke, leave it for about 5 minutes because the smoke indicates the
burning of the water content has evaporated. After 5 minutes cover the stove with a pyrolisator
cover and cover it with sand or clay, prepare a shelter to accommodate the condensed liquid
vinegar fumes. After the combustion is complete, close the furnace and remove the bamboo from
the condensation tube and close it tightly, wait a moment for the liquid vinegar to come out of the
condenser. The results showed that the yield of liquid vinegar produced with an average value of
2.56%. The engineering quantity used is capable of producing 0.51 kg/hour liquid vinegar with a
raw material weight of 19.5 kg.
