Excuse me, what is the ratio of hand-ground soybean milk, beans and water?

Process flow: selecting beans → peeling → soaking beans → grinding → polishing → cooking → filtering → extraction → drying → packaging.

manufacturing method

1. Pick beans and peel them. It is advisable to choose soybeans with full particles and screen out dust and impurities. Crush the selected soybeans, peel them with a peeler, and blow them clean. Peeling is to ensure yellow and white, and improve the utilization rate and yield of protein.

2. soak beans. Soak peeled soybeans in clear water for 4-5 hours in spring and autumn and 7-8 hours in winter, depending on season and temperature. The ratio of water to beans is 1: 2.5. It is advisable to knead beans by hand to swell and harden, not to be soft.

3. Grinding and throwing pulp. Both stone mills and steel mills can be used for pulping. The water used for pulping to filtration is 1: 10 (1 kg beans, 10 kg water), and the pulp is made into juice. Filter with a dryer for 3 times, and the hand-squeezed bean dregs are loose and there is no slurry.

4. Boil and filter the pulp. After the pulp is dried, it flows into a container through a pipeline, is blown by steam, and is heated to 100 ~ 1 10℃. After the pulp is cooked, it flows into the sieve bed through the pipeline, and then it is filtered by 1 time to remove impurities and improve the quality.

5. Extract soybean gluten. After filtering, the cooked pulp flows into the bean paste pot and is heated to about 60 ~ 70℃, and an oil film (oil skin) can be formed in about 10 ~ 15 minutes. Gently cut the film from the middle with a special knife, divide it into two pieces, and extract them separately. When extracting, it is rotated into a column by hand and hung on a bamboo pole to form bean gluten.

6. Drying and packaging. Send the bean gluten hanging on the bamboo pole to the drying room and arrange it in order. The temperature in the drying room reached 50 ~ 60℃, and after 4 ~ 7 hours, the surface of soybean gluten was yellow and white, bright and transparent.
