Technical Field

The invention relates to the technical field of tea oil production, and particularly relates to a tea oil purification method.

Background

Tea oil, commonly known as camellia seed oil, also called camellia oil and camellia seed oil, is pure natural high-grade edible plant oil extracted from common mature camellia seeds of camellia plants in the camellia family, and has golden or light yellow color, pure quality, clarity, transparency, fragrant smell and pure taste. The tea-seed oil squeezed by the ancient method needs to be purified and purified for removing impurities such as colored, acidic and peculiar smell in the tea-seed oil, and the production equipment used at present is single in most functions, so that the whole production efficiency and the treatment effect are difficult to meet the production requirements.
