technical field

The utility model belongs to the technical field of camellia oil extraction, and relates to a pretreatment device, in particular to a camellia seed pretreatment device.

Background technique

Camellia oil is obtained from the seeds of the Camellia oleifera tree. Tea oil does not contain erucic acid, cholesterol, aflatoxins and other additives. After testing, the unsaturated fatty acid in camellia oil is as high as 90%, oleic acid reaches 80-83%, linoleic acid reaches 7-13%, and it is rich in protein and vitamins A, B, D, E, etc., especially its The rich linolenic acid contained in it is necessary for the human body but cannot be synthesized. According to scientific identification, the content of oleic acid and linoleic acid in camellia oil is higher than that in olive oil.

The pressing process of camellia oil in traditional small workshops includes four processes: drying, shelling, crushing, and pressing. Generally, after the camellia fruit is picked and dried, the shell of the camellia fruit is cracked and peeled to obtain camellia seeds, and the camellia seeds are exposed to the sun or dried before entering the stage of oil extraction.

At present, large-scale camellia oil extraction companies generally do not need to go through the process of collecting camellia seeds such as spreading and peeling, and directly purchase camellia seeds that have been peeled and dried.
