1. The variable frequency speed control feather conveying system can adjust the feeding speed at will according to the discharge situation. The position of the conveyor feed port can be made into a pit and the hopper to make it level, which makes feeding easier.
2. The vertical conical forced feeder can press the feathers fed by the feather conveyor into the puffing chamber evenly and stably to avoid the phenomenon that the feathers are too fluffy and the feeding is unstable.
3. The specially customized reduction box makes the operation more stable and suitable for users to operate for a long time.
4. The vulnerable parts are made of wear-resistant alloy material and hardness treatment, which is more durable.
5. The electromagnetic heating system is installed, the temperature is controlled by zones, the temperature rises quickly, the preheating is fast, and the sleeve can be removed after shutdown, which is more convenient for maintenance.
6. The movable independent cutting device can be opened and not used in the early stage of the machine operation. After the work is stable, the cutting device can be fixed to facilitate timely checking of the working status.
7. Different quality of raw wool will affect the output and puffing degree

Characteristics of feather powder: Poultry feathers are mainly composed of keratin. Most of the amino acids in feather keratin are hydrophobic amino acids. Hydrophobic amino acids are distributed on the periphery of keratin. A small amount of hydrophilic amino acids and groups are contained in the peptide bonds and protein skeletons. Many disulfide bonds are formed between the peptide chains, presenting a cord-like structure. The properties are extremely stable and completely insoluble in water, hydrochloric acid and dilute hydrochloric acid solutions, so it is called insoluble protein. Because there are many disulfide bonds and hydrogen bonds between the polypeptide chains of feathers, the structure of feather protein is particularly stable. If they are not treated, the digestive enzymes in the animal digestive tract basically cannot digest and decompose them. Therefore, an extruder is used to puff feathers. The principle is to use the high temperature, high pressure and high shearing effect in the extruder. The feathers are instantly subjected to high temperatures of 160ºC or above and certain catalysts during puffing, so that the feathers are decompressed and puffed at the die hole, destroying the firm spatial structure of keratin and breaking the disulfide bonds. Keratin fibers become smaller protein subunits and linearly arranged peptide chain groups, which are easy to be digested and absorbed by animals. The puffing method is a new technology that has just started at home and abroad. Its advantages are less equipment, low investment, greatly reduced processing costs, less amino acid destruction, high digestibility, no environmental pollution during the production process, and the newly improved puffing machine can also puff pig hair.
Uses of feather puffing: Processed feather powder, as a high-protein resource, has achieved good results in animal husbandry production. It is also widely used in poultry, aquatic products, and pet feed additives to replace part of meat meal and fish meal. Greatly reduces feeding costs.
