Problems solved by technology

Camellia oleifera seeds with high oil content are very viscous after crushing and are easy to agglomerate. If the organic solvent is directly sprayed with a horizontal rotation type organic solvent, the organic solvent cannot fully contact with the camellia oleifera seeds, and will block the solvent channel, making the whole extraction process impossible. conduct

Abstract

The invention relates to a device and a method for extracting oil-tea camellia seed oil at low temperature by taking a liquefiable gas as a solvent, which are used for extracting the oil-tea camellia seed oil. The inner side of an extracting container is at least provided with a group of more than two equal-distance or unequal-distance inlets capable of being opened and closed; the inlets are connected with a pump for inputting a solvent gas through a pipeline; the equal distance or unequal distance refers to a distance from a port end of the pipeline inserting to the inner side of the extracting container to the inner bottom surface of the extracting container; and the inlets capable of being opened and closed are connected with the pump for inputting the solvent gas through different pipelines or the same pipeline. The invention has the advantages that: the utilization rate of the camellia seed oil can be improved, the quality of crude oil is improved, a refining step is eliminated, the production period is shortened and the loss of nutrient substances in the camellia seed oil is reduced.

Description

technical field [0001] The invention relates to a new extraction equipment and method for camellia oleifera seed oil in light industry. Background technique [0002] Camellia oleifera seed oil is edible oil extracted from camellia oleifera seeds. It is rich in unsaturated fatty acids, many of which are essential fatty acids for human body, such as linolenic acid and linoleic acid, and omega-6 and omega-3 series of polyunsaturated Fatty acid ratios are higher than the recommended minimum ratio of 10:1 and are also used in cosmetic and medicinal products. The Chinese government vigorously develops the camellia oleifera industry as an important measure to increase farmers' economic income, improve national health, and ensure national grain and oil security. [0003] At present, the production methods of Camellia oleifera seed oil mainly include cold pressing, hot pressing and organic solvent extraction. The cold pressing method is mostly used in rural workshops, and the oil ...
