method 1 for making camellia oil: drying and crushing: exposing the harvested tea seeds in the sun, or slowly drying with low fire, and grinding round or oblate tea seeds with a stone mill after their shells fall off. Because of the good viscosity of tea seeds, it should be noted that the finer the grinding, the better. 2. Extraction: steam the steamer in water, take the hot grinded grains (steamed materials) and step on the cake quickly. If it is cold, the cake will not be made, which will reduce the oil yield or even not produce oil. Then put the cake into the soil press and squeeze it. When squeezing, punch it hard and squeeze it quickly, and you can't squeeze it back halfway. 4. Refining: The pressed oil is refined to remove magazines. 21% dilute sulfuric acid can be mixed with oil and left standing at 45 tons for one day and night, so that brown magazines can be deposited, or 2 kilograms of acid white bauxite powder can be used for every 111 kilograms, mixed evenly and left standing for one day and night, or the magazines can be separated to make the oil color clear.
