Patent DE-3816822-A1 (DE)
Title: Pasteurising apparatus, transportable in a container structure, for the treatment and hygienisation of pasty substrates, such as, for example, liquid manure
Inventor: RIECHELMANN HARRY
IPC: A01C3/02
Filed: 1988-05-18
Abstract: Because of concentrated mass cattle feeding in many concerns, agriculture generates a large excess quantity of liquid manure, only a maximum of half of which can and should be utilised on the farmer's own fields. These problems in agriculture are fixed and regulated, above all, by the new "Liquid-Manure Prescriptions". On the one hand, in many countries, on account of the excessively high nitrogen values in the groundwater, liquid manure can be applied to the fields only at specific times or untreated and non-"deactivated" liquid manure can no longer be applied. On the other hand, there are many, above all large, agricultural concerns which carry out just cereal farming, without any cattle, and consequently have no natural fertiliser themselves, even though this is available in excess. For large concerns involved in mass cattle breeding, large cost-intensive installations of biogas reactors, with further treatment, are provided for continuous operation. The biogas is used for the farmer's own energy requirement and the excess which occurs is still discharged. For medium and small concerns, a transportable small apparatus for complete treatment, installed in a container structure, is now developed. This apparatus can, if required, be transferred from concern to concern. It can be used as a communal or pay apparatus. The fresh liquid manure accumulated in the existing collecting pits of individual concerns is treated in the small apparatus. It is ... Original abstract incomplete.
