An elimination procedure of citronella oil includes the sticking to tasks:
( 1) Lemongrass is grated at a lowered temperature level of -50 ° C to 20 mesh to obtain lemongrass powder
; (2 )Location lemongrass powder in the elimination pot, consist of 4 times the weight of the extraction agent soybean oil, fill for half an hour, activate the air pump, until the stress in the elimination pot reaches -0.1 Mpa, utilize the anxiety and anxiousness difference in between the removal pot and the solvent storage tank to The solvent butane in the solvent container is instilled right into the elimination pot. Under the problems of elimination temperature level degree of 55 ° C and removal tension of 1.0 MPa, after 7 hours of removal, the elimination fluid becomes part of the splitting up container;
( 3) The get rid of is desolvated and separated in the dividing container for 5 minutes at a temperature of 55 ° C and a pressure of -0.1 MPa. After the solvent is split, it is returned to the solvent container and the lemongrass mixed oil is built up from the electric outlet shutoff of the splitting up storage tank, which is the fragrance. Backyard oil (a mix of citronella vital oil and soybean oil).
After the slag in the removal pot is unwinded and desolvated, the lemongrass slag is accumulated.
The wetness web content of lemongrass symphonious (1) is 10%, and the material-liquid percentage of lemongrass powder to butane throughout the removal procedure symphonious (2) is 1Kg:4 L.
The extraction rate of citronella important oil is (citronella oil-soybean oil)/ citronella lawn * 100%. In this example, the extraction price of citronella important oil is 4.32%.
