A New Way to Utilize the Soybean Oil Cakes

Online, July 30, 2013 (Newswire.com) - The soybean is a kind of legumes that is rich in protein. General soybean oil content is About 22% and the rot yield is above 300%. Practice has proved that the value and benefits of soybean would increase 2-3 times on the basis of the original if you do as follows. Firstly, extract the soybean oil with screw oil press, then make tofu with the squeezed soybean oil cakes, finally feed livestock and poultry with the bean curd residue.

Here is about how to turn waste into treasure, that is how to make full use of soybean to reflect its maximum nutritional value.

Step 1: Extract soybean seeds firstly. Remove impurities in the soybean with a sieve. Next wash and dry them in the sun. Then put them into a small screw oil press for cold pressing. Separate the oil from the oil cakes after cold pressed twice, you would get about 10 to 12 kg oil and approximately 80 kg oil cakes out of every 100 kg soybean. What's more, we would get 3 kg tofu out of every 1 kg of oil cake.Since it comes to soybean oil extraction, Amisy would like to teach you some soybean oil extraction tips: stir-fry until burst before extraction, the temperature is 120-130℃, the moisture is 1.5-2.8％ with the thickness of 0.7 mm. While the oil cake once-drained is too coke, and that would lead to great loss of protein.Twice-drained process method is also a good choice. Stir-fry until six or seven mature with the temperature of 80-100℃. And the moisture is 6-8％, the cake thickness is l.5-2 mm for the first process, and 0.7 mm for the second. However, the oil yield would decline in the twice-drained process.

Then how to make tofu with the squeezed soybean oil cakes?
Step 2: Tofu making process. There is no need to grind oil cake, just boil the soybean milk directly. Add about 70 kg of warm water in every 10 kg of soybean meal. Soak for 7-8 hours in barrel. Stir with a spoon into the pot during heating process to prevent cook coke. After boiled for 2-3 minutes, pour into filters, the final step is pointing pulp. Add the 1:7 gypsum water (ie : 12.5% gypsum, 87.5% water) to the pulp gradually until the block bean curd emerge. Other production procedures are in the same with the traditional tofu.
