Camellia Fruit Peeling Machine is simple and compact in structure, easy to operate, stable in performance, reliable and durable. The following is a brief introduction to the refining process of cold-pressed tea oil.

The processing method of camellia oil is cold pressing at low temperature. Generally, it is cold-pressed at 60 degrees, and the nutritional content is better. The refining process of cold-pressed tea oil is:
1. Storage and preservation of Camellia oleifera seeds: Camellia oleifera seeds are mainly collected by farmers and purchased from Camellia oleifera bases. Camellia oleifera seeds need to be checked, measured, dried, and cooled before they can be stored. The manufacturer of Camellia Fruit Peeling Machine tells you that the general storage temperature is 0 ℃ ~ 30 ℃, and the biochemical principle of post-ripening of plant seeds is used to promote the post-ripening of Camellia oleifera seeds.
2. Pretreatment: the dry camellia seeds put into storage are selected, cleaned and graded, shelled and separated to remove stones, and magnetically separated to remove iron. The pretreated camellia seeds are dehulled, and the solid waste produced by dehulling is mainly camellia husks. After shelling, the kernels are separated from the shells.
3. Cold pressing: use a special cold pressing machine, the pressing temperature is about 70 ℃ ~ 80 ℃, to avoid the darkening of tea seed oil due to high temperature and the loss of active ingredients. The manufacturer of Camellia Fruit Peeling Machine tells you that most of the camellia oils on the market, such as Jinhao and Suisuikang, use this method.
4. Separation of oil residue: Generally, crude oil contains 8% to 10% residue, which should be separated quickly before entering the refinery. The manufacturer of Camellia Fruit Peeling Machine tells you that whether the oil residue is separated in time will directly affect the acid value and color of crude oil. The longer the residence time, the higher the acid value and the darker the color.
