Abstract
Most kitchen hoods in restaurants and hotels uses standard water mist filtration. There are two types of filtration used in the kitchen hood, namely the washing water and water mist. Water mist spray works continuously to filter the system and facilitate cleaning purposes by collecting oil and disposing it. ln a study undertaken previously, for heavy work activity on kitchen hood water mist system, water only is not effective in dissolving oil to clean the filter in kitchen hood system. In fact, water generates a high level of reading on the emission of the kitchen hood plenum system. Flat fan spray nozzle is used only for liquid spray to produce to spray water mist on kitchen hood filtration and require a low pressure water spray. In this study, mixtures of organic citric acid (lemon water) with ratio ( 1: 10) and (3: I 0) were used. Citric acid was selected because it has the same characteristics as detergent for cleaning processes. The AL 75 nozzle was used on kitchen hood system to replace the flat fan spray nozzles for detennining the water and air reduction. Kitchen hood system was built to carry out research and Grease Machine (UL1046) was used to produce a vapor as heavy work cooking activities. Results of the study showed that flat fan spray nozzle with a mixture of citric acid on Lemon 30 % and Water 70% (L30W70) is more effective as it is able to decrease 26.4 % of CO2 emission in comparison to no water mist test. Results of studies using AL 75 (1: I) with L30W70 condition is effective in reducing the amount of CO2 on average, from 5678 ppm to 4187 ppm. Mixtures of organic with experiment instruments showed that the vapor released can be controlled and nozzle AL 75 (1: 1) is effective as a filtration system. The mixed water with citric acid can reduce the emission for heavy work cooking activity on kitchen hood water mist
