The invention discloses a method for producing lemon
essential oil. The method comprises the steps of cleaning and disinfection,
essential oil extraction, oil-water separation, packaging and storage and the like, wherein a scarifying mode is adopted for extracting
essential oil in the essential oil extraction step; lemon fruits are fed into an upper quantitative storage bin of a vertical oil
grinding machine from the upper part of the oil
grinding machine, fall into a middle
grinding plate for grinding, and are discharged from a lateral surface; the lemon fruits continuously roll on the grinding plate under the high-speed rotation of the grinding plate, and also continuously collide with four walls of the oil grinding
machine under the action of
centrifugal force, and the peels of the lemon fruits are impacted by the rotating grinding plate, so that oil vacuoles of the peels of the fruits are completely fractured and broken to
discharge the essential oil. According to the method, the vertical oil grinding machine which is novel equipment is used for extracting the essential oil, so that the
lemon oil extraction rate reaches 0.5 percent; a feeding amount, fruit grinding time and oil grinding rotating speed can be correspondingly regulated according to characteristics of lemons, and
continuous production can be realized; the produced lemons have integral shapes, and can also be processed into products such as lemon slices and dices besides the conventional use of juicing residue formation, so that the subsequent
processing and utilization range of the lemons is widened.
