2. method of ferment bean dregs and soybean meal as fee:
(1) Raw material formula: prepare 1kg of bacterial liquid and 200kg of bean dregs and soybean meal, and add some corn flour, wheat bran, coarse bran, etc. to adjust the nutrition.
(2) Adjusting moisture: Adjust the moisture of the assembled fermented materials to 65-75%. Moisture determination method: Grab a handful of materials by hand, and it is appropriate to disperse when it falls to the ground, because there is little water, the fermentation is slow, and the permeability of water is poor, which will also lead to the odor generated by spoilage bacteria fermentation.
(3) Temperature control: The fermentation should start at a temperature above 15-20℃ for faster fermentation.
(4) Fermentation control: the materials should be completely sealed but not compacted; When fermenting in a container with poor sealing, a plastic bag or plastic sheet should be covered or wrapped outside, tied tightly and sealed; In the process of sealed fermentation, it cannot be disassembled and overturned, and fermentation can be completed in 1-3 days (the finished product has the fragrance of wine, frankincense and acid). The fermented finished products should be sealed immediately after each feeding, and each independent small bag with specifications of 10-30 kg should be used for simultaneous fermentation in large bags or large ponds; The fermented finished products can be stored in sealed bags, or by air drying, dehydration, low temperature drying, or granulation. Fermented finished products should be fed as required.
