The whole process of making tofu with tofu stone mill is commonly known as grinding tofu. Its traditional production process is as follows:

①碾片脱壳：将干黄豆分批倒进一台土砻中碾压，进行脱壳，并使黄豆碾压成片状;

① Milling and shelling: pour dry soybeans into a soil husk in batches for rolling, shelling, and rolling soybeans into flakes;

②浸泡：使清水把已完成脱壳的黄豆片浸泡4～5个小时;

② Soaking: soak the shelled soybean slices with clean water for 4 ~ 5 hours;

③磨豆浆：用人力转动一台豆腐石磨，将清水和黄豆片磨成豆浆，通常由2人操作，即一人不停地转动豆腐石磨，一人根据转速添加黄豆和水;

③ Grinding soybean milk: manually rotate a tofu stone mill to grind clean water and soybean slices into soybean milk. Usually, it is operated by two people, that is, one person keeps rotating the tofu stone mill and one person adds soybean and water according to the speed;

④过滤去渣：用一个密实的面粉袋装上豆浆，然后用力将浆液挤出流一只木桶;

④ Filter and remove the residue: put soybean milk in a dense flour bag, and then squeeze the slurry out into a wooden bucket;

⑤煮沸：将纯豆浆倒进一个大鼎，经煮沸后装进一个按比例配以石膏水的木桶里，并用一支木桨搅匀，然后让其冷却凝结;

⑤ Boiling: pour pure soybean milk into a tripod, boil it, put it into a wooden bucket with gypsum water in proportion, mix it well with a wooden paddle, and then let it cool and set;

⑥加压成形：取几块长约60×60×4厘米的槽形木板，板面呈方格状，并各垫上一块白布，然后用贝壳瓢将已凝结的豆腐花舀到几块木板槽里，用槽里的白布盖住，再压上一块木板和石头，令其减少含水量并成形。一个多小时后，搬开石头和木板并将其反转过来，除去白布，一板乳白色呈方格状的豆腐便新鲜出炉了。

⑥ Pressure forming: take several pieces about 60 long × sixty × 4 cm trough shaped wood board, the board surface is in a square shape, and each is padded with a piece of white cloth. Then, use a shell ladle to scoop the condensed tofu flowers into several board slots, cover them with the white cloth in the slot, and then press a board and stone to reduce the water content and form them. After more than an hour, remove the stones and boards and turn them around, remove the white cloth, and a plate of milky white checkered tofu will be fresh out of the oven.
