1. Purchase:

Northeast China High-quality soybeans, free of insects, moldy beans, black beans, and impurities.

2. Washing:

Wash the soybeans with water before soaking.

3. Soaking beans:

1 pound of soybeans with 4 pounds of water to soak. The soaking time is 8-10 hours in spring, 6-8 hours in summer and 12 hours in winter. (If you use warm

water to soak beans, the temperature should not exceed 35 degrees.) The beans should not be exposed to the water when they are swollen. (Beans are flaky when split in two, with a concave center

meaning they are not soaked through. There is foam means soaked over)

4. grinding beans:

The first mill with a moderate amount of water, the water flow ￠ 8-10 mm, add 14 kg of wet soybeans (about 6 kg of dry beans) tofu with the ratio of water

1:6 that is, 36 kg of raw soymilk (soymilk with the ratio of water is 1:8 to 1:10). The amount of soymilk is less than 40 kilograms.

Note: (After the first grinding, then the soybean residue with water to make a paste, and then grind again to add to the pulp.)

5. Boil the pulp:

Boil the pulp to about 80 degrees and add the defoamer (proportion of 8 grams/40 kilograms) with a long spoon and stir evenly until the foam disappears to 98 degrees when it goes out

. (Soymilk will be heated to 103 degrees with the remaining heat. It can reduce power consumption)

6. Put the pulp:

Put the pulp with a filter rack and filter, natural cooling to 80-85 degrees can be point brine.

7. point brine:

Halogen flakes diluted with water, (ratio of 1:1.5) made of brine, add the appropriate salt, (there is a little salt precipitation is desirable) the temperature of the pulp

in the 80-85 degrees with a spoon to make it in the barrel up and down slowly turning, slowly add brine, flocculent appearance of the brine flow to put a small, appeared

80% of flocculent halting brine, (the amount of about 250-300 ml of points of salt), the amount of about 250-300 ml of brine, the amount of about 250-300 ml of brine. Point brine amount of about 250-300 ml) and sprinkle brine pressure surface on the liquid surface.

8. Squatting tank:

Stand still for about 10 minutes to allow the protein to fully solidify.

9. molding:

Tofu molding box, the first bean bag cloth diagonally spread flat, from the corners of the box to put the soybean brain, put the soybean brain shall not be stirred before the bean bag bra flat cover

good, and then rotary molding, rotary pressure should be the spring slowly extrusion, when the spring has a little gap, you can stop, and so on, so repeated three

times, 10 minutes can be molded.
