Project Description

feather meal extruder machine

Feather meal extruder machine making feather powder to protein additive

Features : No pollution in the production process

Application : Feather meal,feather powder making

Raw materials : Chicken ,duck,hen,boiler feather etc


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 slaughter house, 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 factory, big farm, 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℃ 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.

Advantage of feather powder for animal farming

1.Breeding poultry animals often encounter from the pecking or mutual pecking, pecking anus, pecking toe, pecking eggs and pecking fecal matter, are collectively known as pecking feather disease or pecking addiction. Pecking feather disease not only seriously affect its value, but also cause concurrent anemia, dermatitis, feathers vulnerable to fold, coat dark, and sometimes also cause parasitic breeding. Pecking feather disease and thus early prevention and treatment. Feather powder on this disease have a good therapeutic effect.Feathery powder is rich in sulphur amino acids, so it is beneficial to the growth and development of the poultry in the spring and autumn hairy season. It also reduces the phenomenon of self bite and feather eating of chicken, ducks, pecking anus, hair jumping, mink, and fox.
2.Feather meal is all nutritious food. It can improve the health level of fur animal, improve the breeding ability, promote the improvement of fur condition, and make the hair color become healthier and luster. By extruding (expanding), feather meal can have good palatability, high digestion and absorption rate, good safety, eliminating bacterial contamination of feed, improving growth performance and skin quality, promoting growth and development, making the skin fetching time more than 10 days sooner than usual, raising feed reward, strengthening micronutrient components, having significant effect on preventing hoofs disease, self bite, self mutilation and other nutritional deficiency. It can also improve animals’ anti-stress ability and prevent the occurrence of red claw disease, dermatitis, dermatitis, skin keratosis, scab and chap.
3.The utilization of extruded feather meal can reduce environmental pollution. Unprocessed feathers can not be used directly as feed. However, there are even thousands tons of feather leftovers produced from feather industry or poultry slaughterhouses in some countries every year. If they are discarded everywhere without disposal, they will cause serious pollution to the environment. Besides, at present, the common hydrolytic processing of feather meal will also discharge a large amount of pollutants during the manufacturing process, and some government departments have taken measures to restrict or prohibit the manufacturer to produce hydrolyzed feather powder.

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.

Features of feather meal extruder machine

1. The first automatic raw feather feeding device and unique raw feather advancing structure can truly achieve high output, reduce thelabor intensity of operators and reduce production costs. Energy saving and environmental protection.
2. The structure is novel, and the main shaft screw is a combined structure, which can be adjusted according to differentmaterials, so that one machine has multiple functions and is easy to maintain and use.
3.Ideal processing effect. With automatic temperature control, it ensures feather being processed fully and keeping high digestible protein content.
4. The main components such as the screw are made of alloy materials (manganese, chromium, molybdenum, titanium), which can effectively reduce the oxidation corrosion and wear of the components under high temperature and high pressure, and make the life longer.
