1, cold water brewing law soil tofu, generally only 2.5 kg of soybeans per kilogram of soybeans can be made. The cold water brewing method can increase the rot content of beans by more than 30%. Method: First, the boiled soybean milk is poured into a wooden barrel. When the soybean milk is cooled until it is not hot, it is immediately poured into a bucket of cold water (a proportion of 5 kg of beans put about 10 kilograms of cold water), and then fully stirred to make the temperature even. After 5-10 minutes, add one spoonful of gypsum water to the milk. After adding 3 times, all the tofu was produced. 2. The addition of alkali-soluble soybean protein insoluble protein accounts for about 30% of total protein. These insoluble proteins are present in soymilk and it is difficult to form tofu when sizing. When soaking the beans, adding alkali to the 500:2 ratio of beans and alkali can convert some insoluble proteins into soluble proteins. In this way, the tofu can be solidified at the time of pulping, and the yield can be increased by about 40%. 3, after the first oil production system tofu first soy screening, washed cold pressed twice, so that every 100 kilograms of soybean separated from 9-10 kilograms of soybean oil and more than 80 kilograms of soybean cake. Then use bean cake to make tofu. Making tofu with cold-pressed bean cakes does not require refining. System of law: Each 10 kilograms of soybean meal is about 70 kilograms of water, and it is soaked in a barrel or cylinder for about 8 hours. After mixing, pour it into the pot and stir it while heating to prevent it from sticking. Soymilk can boil after boiling. Gypsum water is slowly poured into the grout until soybean curd appears. Other production methods are the same as traditional methods. The soybean oil produced by this method is not only a high-quality soybean oil, but its tofu is both highly productive, delicate, white and delicious. Every 100 kilograms of soybean can get 30-40 yuan more net profit. 4, the production of slag-free tofu method This method of making tofu because it does not produce soybean curd residue, it does not require filtration and other equipment, and therefore taste good, low cost and high efficiency. Method: Soybeans are first cleaned, soaked, peeled and frozen. Then it is crushed into a paste. Then, the paste is heated to 100°C, and after 3-4 minutes, the heating is stopped. Naturally, the temperature is lowered to 70-80°C, and 2%-5% of the weight of calcium sulfate is added to the soybean to solidify the paste, and then gently crushed. Remove the buoyant solution, place it in a perforated box, cover it, pressurize it, and remove the water.
