How did the grinding stone for the countryside come about? What is the purpose of a grinding stone?

Most of the grinding stones in the countryside are some natural stones from the mountains. This kind of stone, more unique, some sandstone, some likeBasalt。Sandy rock, generally blue-green, there are also jujube red, spicy and spicy groundHard; Like basalt, soft, grayish-black, delicate.

These two stones are relatively scarce. Before, there was no money in the villages, so some farmers went to the mountains to find it. In some areas, there is no one, and it is also very cheap to buy it in the market, at that time, it was about 5 cents a piece.

The main component of whetstone is slate.

There are sand particles on the surface, which can be rubbed with metal materials, and now this whetstone has slowly withdrawn from rural life, and when the whetstone was particularly easy to use before, we also have safflower stone and sand stone.

Whetstones, etc., basically work on it, without much attention. A whetstone is a stone that is used for grinding. Now the vast majority of whetstones used in rural areas are bought from the market, therefore, many young people do not know where the whetstones come from.

According to the application of different knives, the whetstone can be roughly divided into coarse whetstone, medium coarse whetstone, fine whetstone, and extra fine whetstone. For example, a rough whetstone is generally used to sharpen woodcutters and long knives.

The thickness of the axe is used for dirty work, while the barber's razor, the carpenter's long and thin planer, the thin planer, and the handmade.

Chisels, etc., should be finely sharpened with a knifestone. Some knives start with a medium-coarse whetstone and then use a fine whetstone that is too fine. Because of this, when picking up whetstones in the suburbs, they generally look for them according to their own needs and what kind of materials are made of local stones.

Before the millstone was popularized, the loess layer was used with moso bamboo.

The bamboo strips are sandwiched in the loess layer and tamped to dry, but they are not durable, and the rice that is ground out will be mixed with a lot of gravel. With the development of society, the grinding stone, which used to be a good assistant to farmers, is now basically invisible in rural areas, and has long been replaced by electric machinery. There were two types of grinding stones that were commonly used in rural areas, one is polishing, which is used to mill rice and corn flour and the like; There is also a kind of isTerrazzoIt is used to grind rice milk and bean paddles when making rice crackers and water tofu in the countryside.

Most of them are rural, and the people in the family make their own work, using hammers and chisels and other tools, and chisel them out little by hand; It can grind grains and grind wheat into flour, rice seeds into raw rice, and beans into soybean milk.

These millstones are some mountain stones, which are natural rocks; Most rural areas use these grinding stones to sharpen some knives or hoes, which are very common daily necessities for rural farmers.

This is a kind of sand, which can be rubbed well, can better grind various knives, and make the knives sharper.

Stone grinding is a kind of machinery used to process rice, wheat, beans and other grains into flour and pulp.

began to use human or animal power, and in the Jin Dynasty, China invented a water mill powered by water. It is usually made of two cobblestones. The mill is two layers of a plane, and the joints of the two layers have textures, and the grain enters the middle of the two layers from the hole above, moves outward along the texture, and is ground when rolled over the two layers to form a powder.

Precautions for the use of stone grinding:

Just get the stone mill, after the grinding handle is installed, put it in a basin and soak it in water for a few hours, and the grinding handle will hold up the stone grinding hole after absorbing water and expanding, which is convenient to use. Before using the stone mill, you should take some rice and repeat the grind several times, so that the stone mill can be well run-in.

Because the tooth lines of the new stone mill are cut out by hand, the tooth lines are thick and fine, so some of the fine tooth lines will be thinner and sharper, and it is easy to squeeze these small sharp tooth lines when using the new grind for the first time, so it is necessary to run in, and rinse the stone mill with water after the run-in is completed to avoid the stone powder from entering the food, and it can be officially used after washing.

Stone mill: A stone tool that uses human or animal power to peel or grind grain into powder. It consists of two short cylindrical stones of the same size and a grinding disc. Generally, it is erected on a platform made of stone or adobe, etc., and the lower fan (immovable disc) and upper fan ** moving disc are stacked on the stone or wooden grinding disc for receiving flour.

The contact surfaces of the two mills are chiseled with neatly arranged grinding teeth to grind the grain. There are two (small grinding and one) grinding eyes on the upper fan, which are used for leaking grain. There is an iron shaft between the two mills.

There is a large mill with a diameter of more than three feet six inches (meters), which must be pulled by three horses at the same time. Generally, the diameter of the mill is about 80 cm, and one person or a donkey can pull it. The diameter of the small mill is less than 40 cm, and it can be placed in a basket and shaken by hand for grinding pepper noodles.

If you add water while grinding, it is a water mill, which can grind tofu juice, which can be seen in the workshop of making tofu and starch in the past.

Grinding dough, etc., to twist solid things into small particles.

Finally the grains of wheat and something were ground into flour.

Graphite's original name was 硙, and it was not until the Han Dynasty that he was called Mo. The early graphite ruler was a pit dug for the mainstream, and his shape had many shapes. For example, there are rectangles, circles, triangles, and their shapes are irregular.

Stone grinding is a major invention used by the ancient working people of China to do grain processing. He is a machine that can process rice, wheat, beans and other grains into powders and pulps. In modern times, people can use it to grind into soybean milk, soak soybeans, and then put it in a stone mill, and then grind it all the way to add water to turn it into soy milk.

Graphite is also very good for our lives, it is convenient for us, let us save some effort to make things into powder, but also let us eat a very authentic original taste, and because it is made by hand, we will feel more sweet and delicious when we enjoy the food it makes.

And it is said that the stone grinding thing was invented by Lu Ban. Because in those days, people wanted to eat flour and wheat flour to put it in a thing and mash it with a thick stone stick, which was very laborious in this way, so he developed something to help people solve some problems. And in the past, it was generally used to grind with people or donkeys, and its output was very low, until later there was a modern flour processing plant, and then the stone mill was abandoned by the new era, because of its low output, so now many people rarely use the stone mill to grind.

But when I was young, most people used stone mills to grind things like rice and beans. In our childhood, we often pushed it with adults, and it also brought us a lot of fun.

He also has a lot of childhood memories for us. At that time, when there was no modern processing plant, it was also very important to have a graphite, it helped us people to do a lot of things, and of course it was also a very historical thing, so we should not forget the stone grinding thing. It has helped us a lot, and we should also remember this historical legacy.

The above is only my personal opinion, please forgive me if there is any error.

It was invented in the early Warring States period, and after the invention of such a thing, people could process rice, wheat, beans and other grains into a powdered state, and then it was convenient for people to live normally, and plastic could be turned into fine grain.

The time of invention is the late Spring and Autumn Period, the inventor is Lu Ban, who invented the stone mill and can polish the stone, and then the stone can be polished into a variety of shapes, and then it can also be used in life, and then improve the quality of people's lives.

In the countryside, there are a lot of knives, knives are used to chop wood, knives are used to cut pigweed, knives are used to cut vegetables, there are too many knives, and the knives will be dull if they are used too much, and the blunt knives are particularly laborious to use, so they have to re-sharpen the blade, so the whetstone is presented in everyone's daily life, and it has become an indispensable agricultural tool.

One is called sand and gravel, which can be seen with the naked eye: there are a lot of small yellow sand grains in a piece of the kind of stone, the weight is lighter than other stones such as bluestone, and can be broken into various shapes with chisels. A whetstone doesn't take a few times, the whetstone is finished, and it can't stand the use, a better whetstone should be moderately soft and hard, and it can withstand use, and it is comparable to killing iron, and the knife can be sharpened quickly. Therefore, in the countryside, it is more important to choose a good whetstone, usually in a certain area there are some better whetstones, and the whetstones in farmers' homes are mostly from the stones produced by the **, only because the ** stone is relatively easy to use.

People often refer to the whetstone made of this stone as a rough whetstone.

There is a coarse grinding stone, of course, there is a fine grinding stone, in the countryside, people use a coarse grinding stone to grind the knife, the appearance is very rough, and it is not easy to use, which has to use the fine grinding stone, as long as you use the fine grinding stone to sharpen the knife again, the appearance of the knife will be very lubricated, and it will be more and more sharp, and it is more labor-saving to use. And this kind of fine grinding stone stone is also produced in the mountain of a kind of rock mass, not everywhere, as long as there is a certain ** in the mountain, the texture is relatively fine, but not so hard, the color is blue-white, the stone is the same as marble, it can be carved into a variety of utensils, with this kind of stone made of fine grinding stone, is able to sharpen some small and sharp knives such as razors.

It is precisely because of these that in our countryside here, every household has two kinds of whetstones, two different from the mountains.

The magic stone is artificially chiseled out by hand with hammers, chisels and other tools, in the past, people need to grind rice or peanuts, beans and the like into flour to eat or feed chickens and ducks, but the number is not much, generally with grinding stone pig trough, the weight is heavy enough, fixed in a place, not afraid of pigs to damage;

The grinding stones used in rural areas are generally made of local materials, selecting relatively large objects and relatively hard objects, and repeatedly polishing them; Rural grinding stones are generally used to grind things, and beans can be ground and used to make tofu.

Most of them were picked up in the mountains and then formed through artificial modifications. It is mainly sandstone or natural grinding stone, but limestone is also used in some places. Sometimes it can be used to sharpen knives, which can make knives very sharp.

At that time, it was used to grind things, and by crushing these things into flour, coarse grains could be turned into fine grains; Let us eat more refined, improve our quality of life and living standards, and make what we eat richer and more diverse.

It is some stones that are picked up from the outside world, or they may have been made by themselves. It can be used to sharpen knives, it can be used to grind things, it can be used to grind grain, it can also be used to grind soy milk, and it can also be used to feed pigs.
