Peanut shell processing becomes waste and valuable

Peanut shell is a kind of feed source. Peanut shell is crushed and mixed with 15% of rice bran and 30% of bran to make pellet feed. It can be used for feeding pigs, feeding chickens and feeding fish. It is an ideal nutrient-rich feed; Peanut flour is added to the feed with higher crude protein content to make beef more fat. Here are some uses of peanut shells:

1. Cultivate mushrooms Directly immerse the peanut shells in 20% lime water. Disinfect for 24 hours and wash them with clean water. Lay them in a mushroom bed and insert the bacteria. Since the peanut shell contains cellulose and abundant nutrients, it can be used as a culture medium for cultivating edible fungi and as a raw material for producing soy sauce. Tests have shown that using a peanut shell to grow mushrooms has a low cost, good mushroom quality, and the mushroom body is larger than that produced with rice straw, and the yield can be increased by about 20%.

Second, the production of soy sauce first peanut crushed by 50 kg of raw materials heated water soaked 30-35 kg, and then soaked peanut shell steam 1-1.5 hours, the temperature was dropped to 30 °C and then mixed with music medicine. Per kilogram of peanut shell mix 0.25 kilograms of koji, stir evenly on a fine-eye sieve, stack into 3 cm thick into the green house. On the first day, the temperature of the culture room was kept at 37°C-38°C, dropped from 35°C to 32°C on the second day, dropped to 30°C on the third and fourth days, and the raw materials were lumpy and baked when covered with hyphae. , Turn it up and down, take out the smashing on the fifth day. Finally, the fermentation process is carried out. Each 50 kilograms of heavy material is boiled with 90 kilograms of boiling water for fermentation. When the temperature is cooled to 60 DEG C, it is mixed into a large cylinder and put into a baking room. In the first day, the room temperature was kept at 80°C, and the next day was maintained at 60°C. The third day, the oil was baked. Fermented raw materials are calculated according to the raw materials. Each 50 kg is soaked with 125 kg of cold water of Baume 18 degrees for 24 hours. Then the sauce is squeezed and the squeezed sauce is boiled until the boiling point reaches 20 degrees. Soy sauce. The residual slag from peanut shells can also be fed to pigs. According to tests, 150 kg of Grade B soy sauce can be produced for every 50 kg of peanut shell.

Third, in the industrial application According to reports, every 100 kilograms of peanut shells can make residue 3 kilograms. This kind of oil is a good raw material for making soap, and can also produce alcohol, aldehydes, and activated carbon. After the peanut shell is ground into a powder for chemical treatment, it becomes a high-quality artificial wood stick, which can be used to manufacture a variety of exquisite furniture and utensils. Each 50 kilograms of peanut shells can produce 15 kilograms of glue. This type of adhesive has stable performance and high quality. The quality of plywood produced by it exceeds the quality standard of plywood issued by the Ministry of Forestry.
