Analysis of the whole process of poultry feed production

With the intensive development of poultry farming, feed processing is the core link of the industrial chain, and its process standardization and precise parameter control directly affect the breeding benefits. This article systematically explains the technical specifications of the whole process of modern poultry feed production, focusing on the operation points of key equipment such as animal feed pelletizers, and provides the industry with quantifiable quality control standards and process optimization solutions.

Poultry feed production process guide

Modern poultry feed production adopts modular assembly line operation, including raw material reception → primary screening → batching bin → crushing → mixing → pelleting → cooling → packaging 8 major links. The key control points are raw material moisture detection (need to be controlled below 12%) and formula error rate (≤0.3%). Among them, the steam conditioning temperature of the animal feed pelletizer should be stable at 85±5℃, which is the core parameter to ensure the gelatinization degree of starch.

Detailed explanation of poultry feed processing methods

Raw material pretreatment

The system uses a double-layer cleaning screen to remove impurities from raw materials such as corn and soybean meal, and a magnetic separation device removes metal residues. During the crushing process, you need to adjust the screen aperture according to the poultry’s growth stage: use a 2.0mm screen for poultry feed and a 3.0mm screen for adult poultry.

Precision batching system

The electronic weighing system precisely adds trace elements, and you need to dilute the vitamin premix step by step. Actual measurements from a large feed factory show the effectiveness of the automatic batching system. At the front end of the animal feed pelletizer, it can achieve a mixing uniformity CV value of ≤5%.

Poultry pellet feed manufacturing method

The working process of the core equipment animal feed pelletizer is as follows:

Conditioning

The steam pressure of 0.2-0.4MPa makes the water content of the material reach 16-18%

Compression mold

Ring die compression ratio 1:8 (egg poultry feeds) to 1:12 (meat poultry feeds)

Cutter

Adjust the particle length to 1.5-2 times the diameter

Actual measurements show that maintaining a reasonable ring die opening rate of 25-30% can increase production capacity by 15%. At the same time, it reduces the energy consumption of the animal feed pelletizer by 10-12 kW·h per ton.

Production method of crushed feed

Secondary crushing process

Coarse crushing (hammer type) → grading screen → fine crushing (water drop type crusher), this combination reduces power consumption by 18%

Micro powder technology

When using an 80 mesh screen to produce milk replacer feed, a pulse dust removal system is required. This system helps control the risk of dust explosion.

Key points of quality control

Particle durability index (PDI) ≥ 95%

The temperature of the particles after cooling is not higher than the ambient temperature by 5℃

Monthly inspection of wear degree of animal feed pellet mill ring die (＞0.2mm needs to be replaced)

Conclusion

The current mainstream configuration is an animal feed pellet production line with an output of 5-10 tons per hour, and the investment return period is about 2.5 years. We recommend calibrating the gap between the pellet mill rollers once a month, keeping it within the standard range of 0.3-0.5mm.
