NOVELTY - The processing of liquid manure and organic solids for the production of biogas and fertilizer by fermentation, comprises suspending the solids into the liquid manure, coarse crushing the solids in suspension by a coarse crusher of first crushing unit on a largest extension of maximum 5 cm, fine crushing the solids by a fine crusher (10) of the second crushing unit on a largest extension of maximum 1 mm, and homogenizing the solids in suspension by a homogenizer (11) arranged downstream of the fine crusher, which is arranged downstream of the coarse crusher.    USE - Method for processing of liquid manure and organic solids (claimed) for the production of biogas and fertilizer by fermentation.    ADVANTAGE - The process ensures fast and economical production of the biogas and fertilizer with high quality and quantity, reduces required retention period, and increases fermentation speed.    DETAILED DESCRIPTION - The processing of liquid manure and organic solids for the production of biogas and fertilizer by fermentation, comprises suspending the solids into the liquid manure, coarse crushing the solids in suspension by a coarse crusher of first crushing unit on a largest extension of maximum 5 cm, fine crushing the solids by a fine crusher (10) of the second crushing unit on a largest extension of maximum 1 mm, and homogenizing the solids in suspension by a homogenizer (11) arranged downstream of the fine crusher, which is arranged downstream of the coarse crusher. The solid is uniformly dispersed in the suspension. The dispersion is carried out directly or after the further treatment of the fermentation. The first crushing unit breaks voluminous and disrupts fibrous solids in a dry mixture. The second crushing unit crushes the solids in suspension by scissors and cavitation. The homogenizer is led in suspension with the manure. An INDEPENDENT CLAIM is included for a device for processing of liquid manure and organic solids.    DESCRIPTION OF DRAWING(S) - The figure shows a device for processing of liquid manure and organic solids.    Conveying device (3)    Mixing container (4)    Feed pipeline (6)    Fine crusher (10)    Homogenizer. (11)
