Third, how are thousands of copies made?
1. Screening: Choose soybean with full grain, no moth and mildew, and it is not suitable to use newly harvested soybean because its meat is tender and its flesh is less.
2. Soaking: the ratio of soaking material to water is 1:3, the water temperature is 20℃, and the soaking time is 7~8 hours.
3. Pulping: The weight of ground soybean paste should be about 4.5 times that of soybeans soaked in water mill slurry which is 5 times the dry weight of soybeans. The color of soybean paste should be white and the texture should be fine and uniform.
4. Slurry filtration: filter with nylon of 100 mesh, and rinse the residue with clean water at 50-60℃ which is 3 times the dry weight of soybeans.
5. Boiling: When the temperature rises to about 80℃, add defoamer and keep stirring to prevent coking at the bottom of the pot. Soymilk should be boiled at 97~ 100℃ and kept boiling for 3~5 minutes.
6. Paste: Add a quarter of soybean milk to the cooked soybean milk to reduce the concentration and temperature of soybean milk. When the temperature of soybean milk drops to 60~70℃, start to order milk.
Thin thousand tablets: before ordering, put about 3% of the cooked gypsum powder into 10 times of water and stir evenly. After 65,438+00 minutes, order the pulp. When ordering the paste, add gypsum water slowly and evenly, and stir frequently. Chew the soybean milk lightly, and don't stir it randomly. When sesame-sized particles appear, stop ordering and stirring.
1,000-piece thickness: First, put about 4% gypsum gypsum powder into 10 times of water and stir evenly. 10 minutes later, you can pour gypsum gypsum solution into an empty tank, then quickly pour soybean milk into the tank, and use the impulse of pouring soybean milk to stir the slurry evenly. Then cover it and let it stand for 30~40 minutes until the brain cools to about 70℃.
7, broken brain: before the thousand drawers are squeezed, it is necessary to break the tofu brain into sawdust to exclude most of the tofu water, called broken brain.
8. Pouring: put thousands of boxes and drawers on thousands of floors, and another person will help spread thousands of pieces of cloth in the boxes. The four corners should be smooth, not folded or wrinkled. Scoop up the tofu flower in the jar with a big copper spoon, pour it evenly on thousands of pieces of cloth in the box, then fold up the four corners of thousands of pieces of cloth and cover it on the tofu flower. I've already poured 1000 copies. Fall down in turn. The difference between making thick slices and thin slices lies in the number of tofu flowers.
9. Extrusion: Move the poured thousand sheets to the extrusion position, first press the crowbar on the thousand sheets, and then gradually close the crowbar to pressurize. After about 10 minutes, remove all the drawers of these thousands of boxes, and open and press the bottom 30,000. The whole process takes about 20 minutes, and it takes about 40 minutes to make a thousand thick sheets.
10. Stripping: uncover the four corners of the cover cloth, and then pull the two diagonal corners of the cover cloth twice, that is, release thousands of sheets from the cover cloth, and then turn them over. Hold a thousand horns in one hand and pull them up in the other.
