Problems solved by technology

The research results show that bergamot oil mainly exists in the oil capsule of bergamot skin tissue, and there is almost no bergamot oil in the pulp tissue. The existing method for preparing bergamot oil is to directly distill the whole fruit of bergamot after being broken. The pulp part is heated and distilled together, which is unnecessary energy consumption, and the distilled pulp can no longer be used as raw materials for processing other products, resulting in great waste
The distillation process of bergamot oil is a dynamic equilibrium process between the gas-liquid two phases. The existence of the pulp part increases the amount of water added to the distilled material. At the end of the distillation, there will be more bergamot oil in the distilled material cannot be distilled out of the aqueous phase, therefore, reducing the extraction rate of bergamot oil

Embodiment Construction

[0014] The gist of the present invention is to separate the pulp of bergamot before steam distillation, leaving only the peel for distillation to extract bergamot oil, and the obtained pulp is used for processing fruit juice, fruit wine and other products.

[0015] Below in conjunction with example the present invention will be further described.

[0016] Select fresh Bergamot fruit, wash and separate the peel and pulp manually, then break the peel into particles with a particle size of about 1mm, put it into a steam distillation device, add water 4 times the weight of Bergamot peel, Heat distillation, the distillation time is 2 hours, the outlet temperature of the condensed water is controlled at 5°C, the obtained bergamot oil is separated from oil and water, and then anhydrous sodium sulfate is added to remove the moisture contained in the bergamot oil to obtain bergamot essential oil.

[0017] The process flow includes:

[0018] Raw material selection→cleaning→pulp removal...
