Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature cold pressing of tea oil, in particular to a low-temperature cold pressing device for tea oil with a high oil yield. Background Art

[0002] Camellia oil, also known as camellia seed oil, is obtained from the seeds of the tea tree of the Theaceae family and is one of the oldest traditional woody edible vegetable oils in my country. Camellia oil also contains a variety of active substances such as tea polysaccharides, camellia saponins, flavonoids, tea polyphenols, vitamins and phytosterols. Regular consumption has the effects of lowering cholesterol, increasing high-density lipoprotein, reducing low-density lipoprotein, lowering blood lipids, preventing cardiovascular and cerebrovascular diseases, improving immunity, resisting radiation, scavenging free radicals, and preventing tumors. The Food and Agriculture Organization of the United Nations has listed it as a healthy edible oil for key promotion. At present, the basic process of pressing camellia oil is: the oil tea seeds are crushed, dried, steamed, pressed, and filtered in turn to obtain pressed camellia oil. This pressed camellia oil (commonly known as earth-pressed camellia oil) can retain a rich flavor.

[0003] The existing camellia oil cold pressing process has a low oil yield of raw materials, which easily leads to waste of raw materials. In addition, there is a lack of a process for filtering oil residue before collecting the tea oil. The presence of oil residue can easily lead to blockage in the oil discharge channel in the later stage, thereby reducing the quality of the tea oil in the later stage.

[0004] Secondly, if the tea oil seeds are not filtered out of impurities and stone particles before being put into the cold pressing device, it will damage the pressing mechanism components in the device, reduce its service life, and affect the quality of the tea oil, which urgently needs to be developed.
