Description

Technical Field

[0001] The present application relates to the development and application of camphor oil, and in particular to a distillation device for extracting camphor oil from water vapor with easy control of water vapor temperature and camphor oil. Background Art

[0002] Camphor oil is extracted from the undehydrated leaves of the camphor tree (such as fresh camphor leaves) through steam distillation. It is a mixture of dozens of chemical substances. After refined processing, camphor oil extracted through steam distillation can be used in medicine and fragrances. For example, it is used as a raw material for high-end fragrances such as lilac and lily of the valley.

[0003] The existing method of extracting crude camphor oil is to put camphor leaves into the cavity of an extraction tank, then cover the tank, and heat the camphor leaves in the extraction tank cavity through a heat exchanger located outside the cavity and in the interlayer of the extraction tank to volatilize the crude oil in the camphor leaves. The crude oil gas in the cavity is collected and sent to a condensing device for condensation to obtain crude oil. The crude oil is further refined for use in medicine, spices, etc., for example, as a raw material for high-end spices to synthesize various fragrances such as lilac and lily of the valley.

[0004] The existing apparatus for extracting camphor oil by steam distillation has the following defects: (1) Since there are more camphor leaves to be extracted, under the action of gravity, the density of the camphor leaves in the bottom layer is significantly greater than that of the camphor leaves in the upper layer. Even if the heat distribution in the cavity is uniform, the amount of heat that can be obtained per unit of the camphor leaves in the bottom layer is significantly lower than that of the camphor leaves in the upper layer. As a result, the steam temperature used for heat exchange is difficult to control. If it is too high, some of the camphor leaves will be carbonized and affect the quality of the crude oil. If it is too low, the crude oil yield will be reduced. (1) The interlayer heating method makes the heat distribution in the cavity uneven on the one hand, and the heat conduction distance is long on the other hand, resulting in a large loss of thermal efficiency.
