Description

Technical Field

[0002] There is a certain amount of essential oil in the citrus peel, which usually needs to be pierced before recovery. There are generally two methods to extract citrus essential oil, one is distillation and the other is extrusion. The distillation method has high essential oil purity, but low production efficiency, while the extrusion method has high production efficiency but low essential oil purity.

[0003] Conventional citrus essential oil extraction and squeezing equipment is bulky, occupies a large indoor space, and has low applicability. In addition, the current small-scale preparation of citrus essential oil is generally done by holding the citrus, removing the citrus skin with a grater, and then squeezing the skin. During the peeling process, it is inconvenient to control the contact force between the grater and the citrus. On the one hand, the citrus pith or even the pulp may be cut off, resulting in a reduction in the purity of the essential oil. On the other hand, the hand holding the citrus may contact the grater during the grating process, which may cause finger injuries, and the safety is low. Therefore, a person skilled in the art provides a citrus essential oil extraction device to solve the problems raised in the above background technology. Utility Model Content
