The production process of dried bean curd sheets is complex and requires strict control at each stage to ensure product quality.

　　Dried bean curd sheets are made from soybeans. The detailed production process and key control points are introduced below:

　　Production Process

　　1. Selection of materials: Select fresh soybeans with full grains and remove dust and impurities.

　　2. Peeling: Use a dehulling machine to crush and peel the soybeans, and blow away the outer skin.

　　3. Soaking: Soak the peeled soybeans in water approximately 4 times their volume. The soaking time depends on the season and temperature. In winter, it takes more than 12 hours, in summer 2-3 hours, and in spring and autumn 4-5 hours.

　　4. Grinding: Put the soaked soybeans into a blender or stone mill, add an appropriate amount of water, and stir into a paste.

　　5. Boiling and filtering: Boil the ground soy milk and then filter to remove impurities.

　　6. Extraction of dried bean curd sheets: Heat the cooked soy milk to a suitable temperature. An oily film will form on the surface of the soy milk. Use a tool to open and lift it, and hang it on a bamboo pole.

　　7. Drying: Send the bamboo poles filled with dried bean curd sheets to the drying room for drying. Control the room temperature at 35℃ to 40℃. The product is finished when the surface of the dried bean curd sheets is yellowish-white and bright and translucent.

　　8. Packaging: Package the finished dried bean curd sheets.

　　Key Control Points

　　1. Raw material selection: The quality of soybeans directly affects the quality of dried bean curd sheets.

　　2. Fermentation: Pay attention to controlling the fermentation time and temperature.

　　3. Steaming/Boiling: Adjust the steaming/boiling time to ensure that the dried bean curd sheets have good toughness and unique taste after shaping.

　　4. Drying: The drying time and environment need to be controlled. Generally, it is dried in a ventilated and dry place.

　　In summary, the production process of dried bean curd sheets is complex and requires strict control at each stage to ensure product quality.
