Method for extracting cinnamon oil using fluidized-bed and apparatus thereof

Abstract

The present invention discloses a method for abstracting cassia oil by using a fluidized bed and a device thereof. The method uses steam as fluidizing agent, cinnamon leaves are fiercely stirred in the fluidized bed, so that the cinnamon leaves contacted with steam can be constantly refreshed, thus the oil yield of the cinnamon leaves is increased. The device mainly comprises a steam generator, the fluidized bed, a condenser and an oil-water separator; wherein, the steam generator is connected with an air inlet on the lower side of the fluidized bed; an outlet on the top of the fluidized bed is connected with the input end of the condenser; the output end of the condenser is connected with the inlet of the oil-water separator; a distribution plate, which is used to uniformly distribute gas, is mounted on the bottom of the fluidized bed and positioned over the air inlet. The present invention, which has the advantages of short operation time, high oil yield, low unit energy consumption, etc., is applicable to the abstraction of substances such as vegetable oils.

Description

technical field [0001] The invention relates to the technical field of extraction of forestry chemical tree content, in particular to a process and equipment for extracting cinnamon oil from branches and leaves of osmanthus or extracting extracts such as other plant aromatic oils. Background technique [0002] Cinnamon oil has high utilization value in food and medicine, and has become one of the important sources of natural spices. Cinnamon oil is the essential oil extracted from the branches, leaves, bark and seeds of the cinnamon tree, and is the main processed product of the cinnamon tree. my country is a big producer of osmanthus oil, and the osmanthus oil produced in Guangxi and Guangdong accounts for about 80% of the world's output. my country's annual export volume of cinnamon oil is more than 1,000 tons, mainly to the United States, France and other countries. The demand continues to grow, and the demand for cinnamon oil products in the domestic market is also incr...

AI Technical Summary

Problems solved by technology

[0011] Although the above methods can improve the oil yield of cinnamon oil to a certain extent, the operation time is relatively long and the extraction of cinnamon oil is not thorough.

Because the distillation pot used is a fixed bed, all the laurel leaves that cannot be touched by water vapor, even if the time of entering water vapor is as long as 2 to 3 hours, some osmanthus leaves cannot be digested because they do not interact with water vapor well. well extracted cinnamon oil

Therefore, the extraction rate is relatively low with traditional distillation pots, which consumes time, wastes energy and resources
