FORFARANDE FOR HOJNING AV FODERVERDET HOS HALM I BALFORM

摘要

The invention relates to a process for increasing the feed value of lignocellulosic materials by contacting the material with an alkaline liquid. The alkaline liquid supplied in excess is allowed to run off the material before any essential alkalization effect has been reached. After the liquid absorbed in the material has provided its effect an acid solution or nutritive solution is added to the material for neutralization of non-desired excess of alkali. Said solution is applied in such an amount as to at least correspond to the residual absorption capacity of the material resulting after the drainage due to the effect of alkaline liquid absorbed by the material. The invention also provides for an apparatus suitable for carrying out such process.
