By animal flour one understands a feed for utilizable animals, which result during the processing of meat.

Raw material

Ended, dead or stillborn or parts of it as well as battle wastes and spoiled food of animal origin, which are to be eliminated innocuous, to animal flour are converted. The predominant part of the raw material are the battle wastes.

Procedure

The raw material is cut up first in rough or fine crushers in approx. 50 g and/or 20 g heavy pieces. Then it is sterilized: Up to the decay and given subsequent treatment then under 1,3 bar steam pressure 20 min. are cooked with 133"°C. Depending upon procedures now the fat is removed and the material is then dried or turned around. With Tetrachlorethen (BY) the fat is extracted or removed by presses (e.g. worm extruders, centrifuges). In the last step the material husbands becomes.

The extracted fat is continued to process in another procedure. From this for example grease for technical applications or fatty acid methyl ester ("bio Diesel" becomes).

further kinds

Blood flour: dried blood from the battle procedure
Meat fodder flour, meat bone flour: differs from animal flours by the higher portion of bones
Fodder bone pellet: cut up, degreased bones, serves primarily as mineral material carrier

For and against

Animal flour is as protein feeds a spare possibility for the soy bean, which is mostly imported in Europe. Its biological priority is dependent on the quantitative proportions of the Ausgangsmaterialen, in particular from the portion of meat and/or kollagen and keratinreichen body components as well as blood.

The use as feeds was forbidden in consequence of the BSE illnesses of cattle in the European union, because the feed is regarded of animal flour of sheep gotten sick with scrapie as a possible trip of BSE. As a cause a not sufficiently high and sufficiently long heating of the material is assumed, because in Great Britain the regulations were loosened in this connection at the beginning of the 1970er years.

Today a substantial portion of the animal flour is burned as source of energy. It is added to the coal on the one hand in brown coal power stations, and used on the other hand in Zementfabriken for process heat production.
