Coffee processing plants produce coffee oil fume during the roasting of coffee beans, and these oil fume need to be treated in accordance with environmental protection requirements.
Causes of coffee oil fume:
Coffee beans contain about 20% oil. The palmitic acid and linoleic acid content in the fatty acid composition of coffee oil account for half. After about 5-25 minutes of roasting (depending on the selected temperature), green coffee beans will lose part Humidity turns into yellow. During this process, the coffee beans will expand and transform from a firm, high-density green bean state to a low-density fluffy state. After this process, the volume of the coffee beans will approximately double, and they will begin to appear light brown after being lightly roasted. After this stage is completed, the heat will decrease. The color of the coffee quickly turned dark.
When the preset roasting depth is reached, as the roasting time increases, the coffee beans themselves will produce oil. When the finished product comes out, it will produce oily smoke when it encounters cold air. The oily smoke is mainly composed of linoleic acid, oleic acid, palmitic acid, and stearin. It is composed of fatty acids such as acid.
