Extrusion pelleting process in poultry feed pellet machine

In the modern poultry breeding industry, efficient utilization of feed and nutritional balance are the keys to ensuring the healthy growth of animals and improving breeding efficiency. As an important equipment in the field of feed processing, the poultry feed pellet machine not only significantly improves the physical properties and nutritional value of the feed through its unique pelleting process, but also further meets the nutritional needs of poultry at different growth stages. The extrusion pelleting process occupies an important position in poultry feed production with its unique advantages.

Scientific principles of extrusion granulation process
Extrusion pelleting is different from the pressing method in that the feed raw materials are forced through a mold of a specific shape through extrusion to form continuous feed strips, which are then cut into pellets. During this process, the material is subjected to strong shear force and friction in the mold, thereby achieving full mixing and plasticization of the feed.

Utilization of shear force and friction force:
During the extrusion pelleting process, feed ingredients are forced through narrow passages in a die. Due to the fixed shape and size of the channel, the material is subject to strong shear force and friction when passing through. The effect of these forces not only helps to uniformly mix the materials, but also fully plasticizes and disperses the fat, protein, fiber and other components in the feed raw materials, thus improving the uniformity and nutritional value of the feed.

Realization of mixing and plasticizing:
During the extrusion granulation process, the material stays in the mold for a long time and is subject to continuous shear and friction. This long-term mixing and plasticizing process allows the various components in the feed ingredients to more fully penetrate and combine with each other to form particles with a tight structure and uniform texture. This kind of particles not only has a smooth surface and uniform particle size, but also has better physical stability and nutritional value.

Characteristics of extrusion granulation process
The particle surface is smooth and the particle size is uniform:
The granules produced by the extrusion granulation process have a smooth surface and uniform particle size, which helps to reduce feed breakage and dust generation during transportation and storage. At the same time, the uniform particle size can also ensure that poultry can obtain balanced nutritional intake when eating and improve feed utilization.

Flexible adjustment of particle size and shape:
The extrusion pelleting process is highly flexible and can flexibly adjust the size and shape of the granules according to the different growth stages and nutritional needs of the poultry. For example, for young poultry, smaller, easier-to-swallow pellets can be produced, while for adult poultry, larger, nutritious pellets can be produced. This flexibility not only meets the individual nutritional needs of the poultry, but also improves feed palatability and digestibility.

Improve the physical properties and nutritional value of feed:
During the extrusion pelleting process, the material is subjected to strong shear force and friction in the mold, so that the various components in the feed raw materials are fully mixed and plasticized. This process not only improves the physical properties of the feed, such as hardness, density and stability, but also improves the nutritional value of the feed, such as protein utilization, fat dispersion, etc.

Practical application of extrusion granulation process
Optimization of feed formula:
The extrusion pelleting process provides the possibility for optimization of feed formula. By adjusting the shape and size of the mold, particles of different shapes and sizes can be produced to meet the nutritional needs of poultry at different growth stages. At the same time, the shear force and friction force during the extrusion process also help to fully mix and plasticize the various components in the feed, thereby further improving the nutritional value and utilization of the feed.

Improve poultry growth performance:
The feed pellets produced by the extrusion pelleting process have smooth surfaces and uniform particle sizes, making them easy for poultry to eat and digest. This kind of feed can not only improve the feed intake and digestibility of poultry, but also reduce feed waste and the occurrence of intestinal diseases. At the same time, since the components in the feed are fully mixed and plasticized, the poultry can more fully absorb and utilize the nutrients in the feed, thereby improving its growth performance and breeding efficiency.

Reduce production costs and environmental pollution:
The extrusion pelleting process not only improves the utilization rate and nutritional value of feed, but also reduces production costs and environmental pollution. Due to the moderate hardness and density of the feed pellets, feed breakage and dust generation during transportation and storage are reduced. At the same time, since the various components in the feed are fully mixed and plasticized, the poultry can more fully absorb and utilize the nutrients in the feed, reducing residues and pollutant emissions in the feces.

The importance of extrusion pelleting process in poultry breeding
Promote healthy growth of poultry:
The feed pellets produced by the extrusion pelleting process are nutritionally balanced, easy to digest, and can meet the nutritional needs of poultry at different growth stages. This kind of feed can not only improve the growth rate and immunity of poultry, but also reduce the occurrence and spread of diseases, thereby promoting the healthy growth of poultry.

Improve breeding efficiency:
The extrusion pelleting process reduces production costs and environmental pollution by improving the utilization rate and nutritional value of feed. At the same time, due to the moderate hardness and density of the feed particles, feed waste and breakage rate are reduced, and breeding efficiency is improved. In addition, since the various components in the feed are fully mixed and plasticized, the poultry can more fully absorb and utilize the nutrients in the feed, further improving breeding efficiency.

Promote the sustainable development of poultry farming industry:
As an efficient and environmentally friendly feed processing technology, the extrusion pelleting process not only meets the nutritional needs and production efficiency requirements of the poultry breeding industry, but also promotes the sustainable development of the poultry breeding industry. Through measures such as optimizing feed formula, improving feed utilization and reducing environmental pollution, the green, low-carbon and sustainable development of the poultry breeding industry has been achieved.

The extrusion pelleting process has unique advantages and broad application prospects in poultry feed pellet machines. By making full use of the shear force and friction of the material in the mold, the feed is fully mixed and plasticized; by flexibly adjusting the size and shape of the particles to meet the nutritional needs of poultry at different growth stages; by optimizing the feed formula, improving the feed utilization rate and environmental pollution reduction to promote the sustainable development of the poultry breeding industry.
