| titleOfInvention | Method for extracting volatile oil from industrial hemp |
| abstract | The invention provides a method for extracting volatile oil from industrial hemp, which can solve the technical defect that the volatile oil component of the industrial hemp is not utilized but is discharged along with waste gas in the prior art. The invention provides a method for extracting volatile oil from industrial hemp, which comprises the following steps: 1) drying and dehydrating industrial hemp flowers and leaves; 2) pulverizing the dried and dehydrated industrial hemp flowers and leaves in the step 1) into powder, and removing industrial hemp seeds; 3) placing the industrial hemp flower and leaf material treated in the step 2) in a heating and drying device; the air outlet of the heating drying device is connected with a condensing device, and the condensing device is used for condensing the gas exhausted from the air outlet and obtaining condensate containing volatile oil; 4) extracting the condensate obtained in the step 3) by using an extracting agent and taking supernatant; 5) washing the supernatant obtained in the step 4) with water and removing the water layer, and distilling the obtained organic layer. |
