Stone ground tofu is a kind of green food with high nutritional value, which is made by the combination of modern technology and traditional technology. In the past, stone tofu was made by driving the stone mill to rotate with the power of human or animal, while the production technology of modern stone tofu is combined with the machine, and the machine generates power to drive the stone mill, which saves time and improves efficiency.

電動石磨豆漿機傳統的石磨與現代的磨漿機原理融為一體的石磨機械, 產品在不改變研磨原理,改用電力推動，為、綠色、的新型食品加工機械電動石磨,磨齒均勻運轉速度慢所磨制的豆類產品充分保留了豆類的本色及純正香味，不僅豆制品含量高、營養成分多，而且漿質細膩，豆香濃郁，又保留了豆類產品所富含的多種微量元素, 磨出的豆漿既均勻又細能讓豆類產品充分釋放蛋白質，含有的獨特礦物質與大豆營養元素天然混合、渾然一體。

Electric stone mill soybean milk machine is a stone mill machine integrating the principles of traditional stone mill and modern pulp mill. The products are driven by electricity without changing the grinding principle. It is a new type of food processing machine with high efficiency, green and environmental protection. The electric stone mill has uniform grinding teeth and slow operation speed. The price of the ground beans fully retains the natural color and pure flavor of beans, not only the content of bean products is high It has many nutrients, fine pulp quality and rich bean flavor, and retains a variety of trace elements rich in the price of bean products. The ground soybean milk is both uniform and fine, which can fully release protein from bean products. The unique minerals contained are naturally mixed and integrated with soybean nutrients.

石磨豆腐是由電動石磨豆漿機精心碾壓而成，不像純機械生產的豆腐由于長時間高而使豆腐中的蛋白質大量流失。并且石磨豆腐外觀上塊形完整，軟硬適度，質地細嫩，無雜質，具有特殊香味，味道純正清香。顏色白色中略帶黃色，富有彈性，口感。

Stone ground tofu is carefully rolled by an electric stone ground soybean milk machine. Unlike tofu produced by pure machinery, the protein in tofu is lost due to its high for a long time. In addition, stone ground tofu has complete block shape, moderate hardness, fine texture, no impurities, special flavor and pure fragrance. The color is white with a slight yellow, elastic and excellent taste.

石磨豆腐的制作方法

Preparation method of stone ground tofu

1.原料處理。取黃豆去殼篩凈，洗凈后放進水池內浸泡，冬天浸泡10～12小時，夏天7～8小時。浸泡時間一定要掌握好，不能過長，否則失去漿頭，做不成豆腐。

1. Raw material treatment. Remove the shell and screen the soybeans, wash them and soak them in the pool. Soak them for 10 ~ 12 hours in winter and 7 ~ 8 hours in summer. The soaking time must be well controlled and can not be too long, otherwise you will lose the pulp head and can't make tofu.

2.磨豆漿。黃豆浸好后，使水淹沒過黃豆，用西江電動石磨磨豆漿，因西江電動石磨采用技術,可以一次性把浸泡的黃豆放在石磨下料槽上,而不需要傳統的石磨那樣一點點向石磨加黃豆和水。磨完豆漿就是過濾豆漿的工作了!

2. Grind Soybean milk. After the soybeans are soaked, the water will submerge the soybeans, and the soymilk will be grinded by Xijiang electric stone mill. Because Xijiang electric stone mill adopts advanced technology, the soaked soybeans can be placed on the stone mill discharge tank at one time, instead of adding soybeans and water to the stone mill as a traditional stone mill. Grinding soybean milk is the work of filtering soybean milk!

3.沖豆漿。將水燒開后，沖入磨好的豆漿中，沖的過程中一邊攪拌一邊沖，使沖得均勻。此步可以令豆漿更均勻,出漿率高,濾出來的豆漿更濃郁。（開水比冷水沖豆漿的好處）

3. Make soybean milk. After boiling the water, flush it into the ground soybean milk. During the flushing process, stir and flush it at the same time to make it flush evenly. This step can make soybean milk more uniform, high milk yield and richer filtered soybean milk. (boiling water is better than cold water for soybean milk)

4.濾豆漿。將沖好的豆漿倒入過濾桶內進行過濾，過濾時不要讓豆腐渣混進豆漿內，否則豆腐就不嫩滑了，過濾過程中不停往過濾桶內加水，水量不必過大，能沖下漿即可。

4. Filter soybean milk. Pour the flushed soybean milk into the filter barrel for filtration. During filtration, do not let the bean curd residue mix into the soybean milk, otherwise the bean curd will not be tender and smooth. During the filtration process, keep adding water to the filter barrel. The amount of water does not need to be too large, and the milk can be flushed.

5.煮漿點漿。把過濾出的生漿倒入鍋內煮沸，不必蓋鍋蓋，邊煮邊撇去面上的泡沫。火要大，但不能太猛，防止豆漿沸后溢出。豆漿煮到溫度達90～110℃時即可。溫度不夠或時間太長，都影響豆漿質量。將適量食用氯化鎂（鹽點）放進水中溶解，將溶液沖入剛從鍋內舀出的豆漿里、用勺子輕輕攪勻，數分鐘后，豆漿凝結成豆腐花。（點漿根據各地方不同的風味可以鹵點，鹽點或石膏點）

5. Boil and dot the pulp. Pour the filtered raw pulp into the pot and boil it. Do not cover the lid of the pot, while boiling and skimming the foam on the surface. The fire should be big, but not too fierce to prevent the overflow of soybean milk after boiling. Soymilk can be boiled to 90 ~ 110 ℃. Insufficient temperature or too long time will affect the quality of soybean milk. Dissolve an appropriate amount of edible magnesium chloride (Salt Point) in water, flush the solution into the soybean milk just scooped out from the pot, gently stir it with a spoon, and after a few minutes, the soybean milk condenses into tofu flowers. (according to the different flavor of each place, the point slurry can be brine point, salt point or gypsum point)

6.壓豆腐。將點好的豆腐花用勺子輕輕舀進已鋪好包布的木筐（或其它容器）里，盛滿后，用包布將豆腐花包起，蓋上板，壓1-2小時，即成豆腐!

6. Press tofu. Gently scoop the ordered tofu flowers into a wooden basket (or other container) with a spoon. When it is full, wrap the tofu flowers with cloth, cover the board, and press for 1-2 hours to form tofu!
