How to Improve Feed Pellets Quality

How to Improve Feed Pellets Quality
Research has concentrated primarily on the benefits of feeding pellets versus mash. Pellet quality has become more important in the swine and poultry industries as integrators continue to expand and recognise the value of feeding quality pellets. It is one of the important methods for modern feed companies to improve product quality by upgrading their process technology. Let us go through the whole production process and emphasise step by step where improvements can be made.
1. feed particle size
Generally, feed particle size should take consideration of many factors like feeding method, process costs, capacity and growing characteristics of the animals. Particle size should be no more than 1/3 of the diameter of the pellet. Appropriate feed particle size can improve digestion rate of the nutritious elements. Research has shown that when the average particle size of corn in sow feeds is reduced from 1,200 µm to 400 µm, its digestion rate could be raised by 14%, dry matter in manure could be reduced by 21% and nitrogen output would be lowered by 31%. The key point of particle size control technology is to grind each raw material to the best size suitable for digestion to ensure each batch of feed can acquire best growth efficiency and economic profit. It is necessary to study the best digestion size of each raw material for different animals.

2. mixing uniformity
Uniformity is vital for pellets quality as it will determine whether the animal can get full nutrition from the feedstuff. It is critical to choose the right mixer, mixing period and feeding method to ensure uniformity and proper nutrition.Technical improvements in the mixing process should focus on the following aspects:
☆Select proper mixers to ensure uniformity;
☆Add materials in correct order (big ones first and small ones later);

☆Add all materials in proper amount and order.    ☆In case of change of formula, clean mixer thoroughly to avoid cross contamination;
☆Keep transportation distance and height of materials after weighing to a minimum and do not use conveying equipment like pneumatic devices which could cause separation of materials.
3.conditioning process
Conditioning is the primary control point of pellet quality which includes temperature, time, water and gelatinisation degree of starch. The secondary control point covers fines rate, cooling temperature, moisture, cutting blade even degree and water durability of feed. To meet these requirements, proper steam supply and control system, conditioning, pelleting, cooling and screening equipment should all be equipped and the control parameters should be scientifically adjusted.
