Animal Feed Extruder Machine

There are three main aspects of the role of the feed puffer:
1, the crushing of feed: feed expanding machine can effectively crush the feed, so that the particle size of the feed is smaller, easier to be digested by livestock, improve the digestive efficiency of the feed.
2, feed expansion: feed expander can effectively expand the feed, so that the feed particles become larger, easier to be digested by livestock, improve the digestive efficiency of feed.
3, feed mixing: feed expander can effectively mix different kinds of feed, so that the nutrition of the feed is more balanced, easier to be digested by livestock, improve the digestive efficiency of feed.
The role of feed expander is not only to improve the quality of feed, but also to improve the availability of feed, improve the digestive efficiency of livestock, improve the utilization rate of feed, and improve the productivity of livestock. Feed expanding machine can not only improve the quality of feed, but also improve the availability of feed, improve the digestive efficiency of livestock, so as to improve the productivity of livestock and improve the efficiency of farming.

Extrusion destroys the cell wall structure of the oilseed, releasing the oil from it, and this processing method improves the utilization of the oil. Expansion can also be fat and starch or protein together to form a composite product (lipoprotein) or (lipopolysaccharide), reducing the content of free fatty acids, while passivating the esterase enzyme, inhibiting the degradation of fats and oils, reducing the rancidity of fat and oil components in the process of storage and transportation of the product, which is conducive to the preservation of the feed for a long time.
Expanded feed particles are small, crispy, and release a burnt flavor, palatability improved. The expanded feed becomes loose and disorderly structure, this change provides a larger contact area for enzymes, which is conducive to the contact of starch chain, peptide chain and digestive enzymes, which is conducive to the digestion and absorption of feed, thus improving the digestibility of feed.

After extrusion, starch undergoes two main changes. First, the starch paste, puffing process disassembles the dense crystal structure of starch molecules, crystal structure absorbs water and disintegrates, hydrogen bond breaks, puffed starch granules rupture, turning into a viscous molten body. At the outlet of the puffing machine, due to the instantaneous pressure drop, the steam is instantly dissipated in large quantities, a large number of puffed starch granules disintegrate, the starch is pasty and many puffed feeds with micropores are formed. On the other hand, it is starch degradation, the average molecular weight of starch decreases significantly, and small molecule structure of oligosaccharides such as maltodextrin can be produced through cleavage. The pasted starch has strong water absorption and much stronger adhesive function than ordinary starch, which can reduce the use of starch in production and provide more choices for other raw materials. At the same time, the pasted starch can combine the protein closely with the starch matrix to form the rumen non-degradable protein body of ruminants, i.e., per rumen protein, which improves the utilization of protein by ruminants.
