100 pounds of fresh fruit can be about 30 pounds of tea seed kernels, this process also have to shell, dry, to artificial, 30 pounds of tea seed kernels, through the pressing method, can be about 20-25% of the tea oil, that is, can be out of the 6-7 pounds of oil, this oil is still impurities, but also have to precipitate in addition to impurities, and finally down, that is, 6 pounds of oil, the cost of fresh tea seed kernels is 300 yuan, the extraction of oil out of the tea wither! Part of the price can be folded, even if the offset artificial oil extraction process of labor costs, the cost per catty of oil is 50 yuan, people still have to invest, but also the profit, you can do the math. This is the traditional earth pressing method out of the oil, traditionally can be eaten, a lot of tea oil producing areas are also so directly eaten.
According to China's current standards for camellia oil, this can only be counted as gross oil, should be refined (refining is deodorized, dewaxed, deacidified, etc., in the middle of the alkali, etc., I am not very familiar with the specific process) after the market, the refining process, the rate of oil still have to be discounted,
Note: This is the traditional method of pressing out of the oil.
There is also a camellia oil, just processing technology is not the same, the price is cheaper, he is processed with the extraction method, the pressing method of the remaining tea wither (tea wither still contains about 10% of the oil) with the six light gasoline extraction extraction, and then separated from the refining, in line with the national standards, the camellia oil purity is also high. Not much to say, you know.
