花生人人皆知，是一种美味的食品，但剩余的花生壳常被当作垃圾处理。但你知道吗，花生壳也是一种具有多种用途的生物资源。首先，花生壳含有大量粗纤维，营养价值高，可以制成动物饲料。其次，花生壳经过发酵后也可以作为肥料，为土地提供养分。最后，由于花生壳富含木纤维，粉碎碳化后可以制成炭和活性炭。
制造动物饲料
A large number of peanut shells will be produced after peanuts are processed by oil extraction plants and food processing plants. In the areas where peanuts are grown, there will also be a lot of peanut shells. It would be a pity to throw away these peanut shells as garbage. But if we make them into animals food to feed cattle, sheep, chickens, ducks and other animals, they not only grow faster, but also can replace part of the concentrated feed to reduce the cost of breeding.
制造燃料
Peanut shells can be used to make biomass briquette. The peanut shells are crushed with a 木材粉碎机 and then crushed into rods by a professional machine under high temperature and high pressure. These biomass briquettes are often used as fuel. For example, it is used for winter heating and industrial boiler fuel, so the recycled peanut shells become the most environmentally friendly and economical new energy fuel to replace coal. These sticks can be further carbonized to make charcoal, and they are also used as fuel.
制造活性炭
废弃的花生壳也可以用来制造活性炭。花生壳经过碳化后，通过化学活化法或气体活化法进一步加工制造活性炭。由于活性炭的孔隙结构非常发达，能很好地吸附水中的金属物质或空气中的少量有害物质。我们在家中通常用活性炭吸附冰箱和浴室的异味。此外，新房中甲醛含量较高，许多人会在室内放一些活性炭以吸收甲醛。
