feather meal extruder machine, feather powder to protein additive
Feather meal extruder machine matched automatic raw feather feeding device and unique structure ,it can truly achieve high output.
Feather meal extruder machine is destroying the firm feather keratin. The space structure of the feather keratin becomes smaller protein subunits or polypeptide chains arranged linearly. The keratin in feathers is puffed to become a crude protein that can be digested and absorbed by livestock, the puffing things are chopped to form feather meal to replace the protein feed components such as soybean meal and imported fish meal in the feed for livestock and poultry.
Extruded feather meals is not only sterilized and matured, but also has good palatability and can be easily absorbed by poultry and livestock,that the digestibility of amino acids reached the level of high-quality soybean meal, which was similar to the level of imported fish meal. It is a kind of high-quality protein feed.
Why we need feather extruder machine? For the farmer who are running a poultry slaughterhouse, it¡s a hard problem how to deal with the large quantity of wastes feather. The most of the chicken feather waste was burned or buried before,which is causing damage to the air and the environment. Poultry feather can be a valuable feed material or pollutant resource. The factor causing this difference is how to make use of it.
With the rapid development of poultry and livestock industry on the world, the demand for protein feed is increasing. As a necessity in the breeding process, feed has high price cost and unstable quality, which has a great impact on the feed conversion rate. It is an urgent problem to develop and produce a new high protein feed with low cost and good quality. Feather extruder machine is the best solution.Zeno brand feather powder making machine adopted advanced design of automatic feeding device and propeller structure, truly low energy and high efficiency. It is particularly suitable for slaughter plants, cashmere factories, feed factories, big farms, etc.
Feather meal extruder machine performs extrusion processing on the feathers. First, the feathers undergo a high temperature and high-pressure process in the cavity of the extruder. At the same time, the feathers interact with the screw and sleeve to generate high shear forces. At this time,the feathers in the machine are molten state. The screw pushes the material axially to the die hole. At the moment of extrusion, due to the sudden decrease of pressure and temperature, the disulfide bonds and hydrogen bonds in feather keratin are broken when they reach a high temperature of 180¡æ and a pressure of 1.5 MPa, The protein content of feather meal can be as high as 80%, the amino acid composition is relatively complete; except for its lysine and methionine are lower than fish meal, the other trace elements are all higher than fish meal.
And its content of cystine ranks first among all natural feeds, which makes it a good source of protein feed.
According to the preliminary calculation in scientist, the production profit of the puffed feather powder is about 150USD per ton, so in the full price feed production and the breeding, the cost of every 1 ton of feather powder can reduce about 450USD. So the total economic profit of extruded feather powder production and application is about 600USD per ton.
The extruding expansion processing technology can on one hand make the feathers; nutritive value greatly improved and be efficiently used, eliminate the source of pollution, on the other hand as the production process is clean and environmental, so the feather powder extruding is beneficial to reduce the environmental pollution.
