What is the difference between traditional fried peanut oil and modern fried peanut oil?

The traditional oil pressing is to fry the oil and press it at high pressure, use an iron pot to burn firewood and press it! It's human repression. After the oil is produced, it is boiled off to precipitate and sold. The oil is fragrant, but the oil output is less than that of modern oil, and the labor intensity is high. However, the cooked oil is resistant to frying and eating, and has less water content. Modern rolling oil, not frying oil, is fast, the oil is not fragrant, the oil is not boiled, and the water content is high, so many people miss the traditional oil and say it is unsanitary. I don't know where to start. Iron-containing iron pots are beneficial to people after eating, and the manpower is based on the lever principle without any pollution. The oil is boiled in the furnace to remove slag and sediment, and there is no water in the oil, which is in line with the concept of honest management. Modern oil rolling speed is fast, either frying or boiling, and the water content is very high, which annoys the people. Not only peanut oil, but also other oils. If we can combine tradition with modernity, we can make a good brand.
