Lu Ban was an outstanding inventor in ancient China. He lived in the late Spring and Autumn Period and was called Gonglei. Because he is from Lu, he is also called Lu Ban. It is said that he invented saws, planers and rulers for carpenters. He also used his wisdom to solve many problems in people's lives. When Luban lived, people wanted to eat rice flour and wheat flour. They put rice and wheat in a stone mortar and pounded them with a thick stone stick. This method is very laborious, the powder is coarse and fine, and it is rarely used at a time. Luban wants to find a way to get twice the result with half the effort. Just use two flat cylindrical stones with a certain thickness to make a grinding fan. There is a short vertical shaft made of iron in the middle of the lower fan, and a corresponding empty sleeve in the middle of the upper fan. After the two fans are combined, the lower fan is fixed and the upper fan can rotate around the shaft. On the opposite sides of the two fans, there is an empty chamber called grinding chamber, and the periphery of the chamber is made into falling grinding teeth. There are grinding eyes on the upper fan. When grinding, the grains flow into the grinding chamber through the grinding eyes, are evenly distributed around, are ground into powder, flow from the cracks to the grinding disc, and are removed by a Luo sieve to obtain flour. Inventor of soybean milk: Liu An, King of Huainan in the Western Han Dynasty, over 900 years ago/kloc-0.
According to legend, Liu An is the king of Huainan and Liu An is a dutiful son. During his mother's illness, Liu An used soaked soybeans to grind soybean milk for his mother to drink every day. Liu's illness soon recovered. Since then, soybean milk has gradually become popular among the people. When Liu An was making an alchemy in Bagongshan, Huainan, he accidentally put gypsum into soybean milk and turned it into tofu. Tofu came out at that time, and many ancient books recorded it.
"Compendium of Materia Medica" records: "Soybean milk is beneficial to underwater qi, controlling wind and heat, and relieving all kinds of toxins". The secret record of prolonging life also records that soybean milk "grows skin, benefits qi and color, fills bone marrow, adds strength and supplements deficiency." According to the theory of traditional Chinese medicine, soybean milk is flat and sweet, nourishing yin and moistening dryness. "A bowl of hot soybean milk in autumn and winter can drive away the cold and warm the stomach and keep healthy." Drinking soybean milk often is good for your health. Soymilk is a favorite drink of China people, and it is also a nutritious food suitable for all ages. It enjoys the reputation of "plant milk" in Europe and America. Soybean milk is rich in plant protein and phospholipids, and also contains vitamins B 1, B2 and nicotinic acid. In addition, soybean milk also contains minerals such as iron and calcium, especially calcium. Although it is not as delicious as tofu, it is higher than any other milk and is very suitable for the elderly, adults and teenagers.

Soymilk made by traditional stone mill is more nutritious. Using stone mill to make soybean milk can make soybean fully contact with air, and the taste is naturally good. The stone mill contains natural minerals, and is rich in natural jute which is beneficial elements selenium and germanium to human body. It is non-radioactive, tough and wear-resistant, finely crafted, green supervised and scientifically polished, which is of great benefit to health. The speed of grinding soybean milk with stone mill is very slow, so that the ground soybean milk is really delicious. Stone grinding flour, which is good for health, was invented by Lu Ban, and it took our ancestors thousands of years to grind it.
