1. First, crush peanut bran and take 50-60%, mix with corn flour about 30%, soybean meal about 10%, and add the amount of fermentation bacteria at 0.5%. Mix the fermentation bacteria and each material thoroughly, then add water and mix well. The moisture content of the material is generally controlled between 65-75.

2. The judgment method is: hold a handful of the mixed fermentation material tightly. Watermarks can be seen between the fingers but no dripping. It is appropriate to loosen the fermentation material and it will spread when it hits the ground. If the water can be squeezed out and does not fall apart when dropped, the moisture content is greater than 75. Too dry or too wet is not good and should be adjusted.

3. Add water and mix well, then put it into a basin, jar, pool, plastic bag and other containers, seal and ferment at natural temperature for 2-3 days, until it smells fragrant, sweet and alcoholic. Feeding. For large-scale fermentation, it can be directly stacked on a clean cement floor or fermentation tank, and covered with a plastic film to seal the fermentation.
