Tea-oil camellia, another name: tea tree, tea oil tree, and white flower tea; camellia oleifera belongs to Theaceae, and is a evergreen small arbor. Its seed can be used for extracting oil (tea oil) for eating, so its name is. The tea oil is clear in color, delicious, rich in nutrition and long in storage life, and is high-quality edible oil; can also be used as lubricating oil and antirust oil for industry. The tea cake is not only a pesticide but also a fertilizer, and can improve the water storage capacity of the farmland and prevent and control pests in the rice field. The pericarp is the raw material for extracting tannin extract.

The oil tea seed oil extraction method has the advantages that the seed frying process is required to be carried out before oil extraction of oil tea seeds, the purpose of seed frying is mainly to reduce moisture in tea seeds and improve the oil yield, if the size difference of the same batch of fried tea seeds is too large, the situation that the water content of a large number of tea seeds is high and the water content of a small number of tea seeds is low can be caused, so that the integral oil yield of the tea seeds can be greatly reduced, shells and tea seeds with different sizes are required to be screened out usually after husking and before seed frying, and the tea seeds with the sizes close to each other are fried in the same batch after screening so as to improve the oil yield.

The existing oil tea vibrating screen is simple in structure, single in function and inconvenient to use, and cannot fully screen oil tea. For this reason, a corresponding technical scheme needs to be designed to solve the existing technical problems.
