How does the traditional oil press squeeze oil?

Oil-pressing technology of traditional oil-pressing plants;

1. Camellia oleifera seeds are picked from tea trees one by one. After harvesting, it needs to go through composting, fruit drying, hulling, seed drying and other processes. , to remove the shell and moisture. When it was first picked, the tea kernel was covered with a hard skin.

2. Dry the tea seeds and peel them. After hulling and drying, the tea seeds are sent to the oil press, and then will enter the substantive oil press stage.

3. Put the sun-dried (or dried) tea seeds into a grinding tank and grind them into powder. In the past, tea seeds in the village were all crushed by physical strength. Now tea seeds can be crushed by a crusher, and of course animal power is also useful. ?

6. Stir-fried tea powder is poured into a special steamer for steaming, which is convenient for making cakes in the next step. The steamer is steaming and fragrant. Steamed tea seeds, the fluidity of their oil is enhanced, and it is easier to produce oil. ?

After the cakes are wrapped, they are stacked together and transported to a special machine or a Mulong press for oil extraction. Next, the core link of camellia oil production is commonly known as "beating oil". ?
