Stone mill flour mill, also known as stone mill flour mill, is a grain milling equipment combined with natural granite and modern transmission technology. The machine has the characteristics of high nutrition and beautiful appearance. It is a relatively good equipment both in terms of price and. The unit is divided into large stone mill, medium stone mill and small stone mill flour mill.

石磨面粉机是用于把米、麦、豆等粮食加工成粉、浆的一种机械。开始用人力或畜力，到了晋代，汉族劳动发明用水作动力的水磨。通常由两个圆石做成。磨是平面的两层，两层的接合处都有纹理，粮食从上方的孔进入两层中间，沿着纹理向外运移，在过两层面时被磨碎，形成粉末。

Stone flour mill is a kind of machine used to process rice, wheat, beans and other grains into powder and pulp. They began to use human or animal power. In the Jin Dynasty, the Han labor invented a water mill powered by water. It is usually made of two pebbles. The grinding is two layers of plane, and the joint of the two layers has texture. Grain enters the middle of the two layers from the hole above, migrates outward along the texture, and is ground when passing through the two layers to form powder.

一、选料炒籽。选成熟饱满、干湿适中的新芝麻，先用簸箕各种杂质，也可用清水漂洗除去漂浮的杂质和沉底的泥沙，然后栈闷起来，使其均匀吃水。炒芝麻时，先用急火加热，当快熟时，渐减火势，并加快搅动，促进烟和水气的放出。芝麻呈黄褐色时，迅速取出，摊开降温，并簸去炒焦的碎末渣滓。

1、 Fried seeds with selected ingredients. Select new sesame seeds that are mature, full and moderately dry and wet. First, use a dustpan to remove various impurities, or rinse with clean water to remove floating impurities and sediment at the bottom, and then stack them up to make them draft evenly. When frying sesame, first heat it with a quick fire. When it is about to mature, gradually reduce the fire and speed up the stirring to promote the release of smoke and moisture. When the sesame is yellowish brown, quickly take it out, spread it out to cool down, and winnow the scorched residue.

二、细磨芝炒酥拣净的芝麻趁热石碾上反复碾磙或小磨上细磨。当把芝麻碾磨稠糊料浆时检查细度，用、食指捻开料浆，不留残渣，越细越好。然后把料浆揽在盆子里，放进盛有开水的锅里用文火加热。

2、 Finely grind the sesame, stir fry, crisp and pick the clean sesame, repeatedly grind it on the hot stone or finely grind it on the small mill. When the sesame is ground to a thick paste slurry, check the fineness, twist the slurry with your and index fingers, leaving no residue. The finer the better. Then take the slurry in a basin, put it into a pot with boiling water and heat it over a slow fire.

三、对浆搅拌。经过磨料操作，加入开水搅拌，就能把料浆中的油代替出来。必须用90度以上的开水，加水量一般是芝麻重量的二分之一左右，分三四次加入，逐次加水量，每次加水后均要搅拌。油浆底部渐呈蜂窝状，大部分油即浮出。后酌量加水定浆，搅速放慢，半小时后将油撇出。

3、 Stir the slurry. After abrasive operation, adding boiling water and stirring, the oil in the slurry can be replaced. Boiling water of more than 90 degrees must be used. The amount of water added is generally about half of the weight of sesame. It is added in three or four times. The amount of water is added step by step, and it shall be stirred after adding water each time. The bottom of the oil slurry is gradually honeycomb, and most of the oil floats out. After that, add water to fix the slurry, slow down the stirring speed, and skim out the oil half an hour later.

四、震动分油。料浆加水搅拌后，大部分油从油浆中分离出来，可用面杖或葫芦类物体在油渣浆中上下震荡，促进渣浆中的小油滴结团浮出。连续震动撇油三次。震动分油时应保持温度在十度，以油的粘度。撇出的香油，若不带浆渣就不要过滤，即为清香的小磨香油。剩下的油渣可做酱油、味精和点心馅等，但要注意及时食用，防止发酶变质，油渣多时可以干藏.

4、 Vibration oil separation. After the slurry is stirred with water, most of the oil is separated from the slurry, and a face stick or gourd can be used to vibrate up and down in the slurry to promote the agglomeration and floating of small oil droplets in the slurry. Continuous vibration skimming for three times. When vibrating oil separation, the temperature shall be kept at 10 degrees to the viscosity of the oil. If there is no pulp residue, do not filter the skimmed sesame oil, which is a fragrant small grinding sesame oil. The remaining oil residue can be used as soy sauce, monosodium glutamate and dessert filling, but it should be eaten in time to prevent enzyme deterioration. The oil residue can be stored dry for a long time
