Abstract

The process for the disposal and/or treatment of feathers and feather wastes such as ground feathers, in particular from chicken slaughter houses, is that the feather material is plasticised or liquefied by means of a cooker-extruder. The end product having a high protein content is suitable, in particular, as an animal feed.

Description

Die Erfindung betrifft ein Verfahren zur Entsorgung und/oder Aufbereitung von Federn oder Federabfällen wie Federmehl, insbesondere aus Hühnerschlachthäusern.The invention relates to a method for disposal and / or Preparation of feathers or feather waste such as feather meal, especially from chicken slaughterhouses.

In Hühnerschlachthäusern fallen erhebliche Mengen an Federabfällen an, die derzeit aufgrund der besonderen gesundheitlichen Vorschriften nur mit großem Aufwand zu Tierfutter aufbereitet werden können. Für die Beseitigung dieser Abfälle müssen die Schlachthäuser oder Hühnerfarmen erhebliche Kosten aufbringen. Es ist bekannt, Federn oder Federabfälle mittels eines Hydrolyseverfahrens aufzubereiten.There are significant quantities in chicken slaughterhouses Spring waste, currently due to the special health regulations only with great effort Animal feed can be processed. For elimination This waste must go to the slaughterhouses or chicken farms to incur considerable costs. It is known to feathers or Spring waste using a hydrolysis process prepare.

Mit diesem Verfahren hergestelltes Tierfutter weist jedoch nur geringe Nährstoffe auf, so daß es als minderwertig anzusehen ist.Animal feed produced using this method However, has only low nutrients, so that it as is inferior to look at.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, das wirtschaftlich zur Herstellung von Produkten mit hohem Proteingehalt aus Federn oder Federabfällen geeignet ist.The invention is based on the object of a method create that economically for the manufacture of products with high protein content from feathers or feather waste suitable is.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Federn mittels eines Kochextruders plastifiziert oder verflüssigt werden.This object is achieved in that the Plasticized springs using a cooking extruder or be liquefied.

Durch die Behandlung von Federn oder Federabfällen mittels eines Kochextruders erfolgt eine erhebliche Veränderung im Gefüge des Federmaterials. Verbunden mit der Verflüssigung oder Plastifizierung des als Abfall anzusehenden Ausgangsmaterials ist eine Sterilisation. Untersuchungen im Labor zeigen eine bedeutende Steigerung der Proteinverwertbarkeit, im Durchschnitt 40% und mehr. Enzymatische Verdaulichkeitstests haben gezeigt, daß das mittels des erfindungsgemäßen Verfahrens behandelte Material als Tierfutter geeignet ist.By treating springs or spring waste with a cooking extruder there is a significant change in Structure of the spring material. Associated with liquefaction or plasticizing what is considered waste The starting material is sterilization. Investigations in Laboratory show a significant increase in Protein usability, an average of 40% and more. Enzymatic digestibility tests have shown that the material treated by the method according to the invention is suitable as animal feed.

Gemäß einer bevorzugten Ausführungsform wird die Extrusion bei einer Temperatur von mehr als 90°C und einem Druck von mehr als 5 bar durchgeführt. Insbesondere wird ein schnell laufender Extruder zur kontinuierlichen Extrusion verwendet. Aber auch andere bekannte Extruder sind zur Durchführung des Verfahrens geeignet.According to a preferred embodiment, the extrusion at a temperature of more than 90 ° C and a pressure of carried out more than 5 bar. In particular, a quick running extruder used for continuous extrusion. But other known extruders are also used to carry out the Process suitable.

Das mittels eines kontinuierlichen Kochextrusionsprozesses behandelte Federmaterial ist insbesondere geeignet zur Herstellung von Tierfutter.With the help of a continuous extrusion process treated spring material is particularly suitable for Production of animal feed.
