According to the normal pressing technology, 100 kg of tea seeds can squeeze out about 20 kg of oil. The price of Nanchuan tea oil is about RMB 0/00 per catty. Although it is on the high side, there is a great demand for tea oil, so the market is in short supply.

The maturity of tea seeds is 1 1 month every year. Camellia oleifera is a plant with the same flowers and fruits. Camellia hung on the treetops when picking tea seeds. After the tea seeds are picked, they should be dried. After drying, it will break the shell, and then take out the black tea kernel, which is the raw material for oil extraction.

Extended data:

Camellia oleifera likes warmth and is afraid of cold. The annual average temperature 16 ~ 18℃ and the flowering average temperature 12 ~ 13℃ are required. Sudden low temperature or late frost will cause falling flowers and fruits.

Sufficient sunshine is needed, otherwise only branches and leaves will grow, resulting in less results and low oil content. Sufficient moisture is needed, and the annual precipitation is generally above 1000 mm, but continuous rainfall at flowering stage affects pollination.
