Pellet feed machines are an important element of the high-quality animal feed production, yet their work efficiency depends on several factors. Be it the production of livestock, poultry or aquatic feed, these are some of the main factors that can guide you to maximize on production, minimize energy use and enhance pellet quality.
We Shanghai Yuanyuda International Trade Co., Ltd. are the high-efficiency pellet feed production lines specialized company. The following are the most decisive factors which determine the performance of pellet machines:
Raw Material Quality and Preparation
Revise particle size and moisture guidelines based on feed type.
The feed ingredients and their formulation have a great influence on the pelletizing performance:
Particle size: It needs to be uniform (0.5-1.5mm) to allow better compression.
Moisture: 12-16 percent is best; dry = binding poorly, wet = clogging.
Fat and fiber content: Materials high in fat help to decrease friction, but can make weaker pellets; materials high in fiber need more powerful compression.
Solution: A hammer mill should be used when a consistent grinding is required and a mixer when the blending has to be homogeneous.
Pellet Mill Die and Roller Design
The core of pelletizing efficiency is die and rollers:
Die hole size: Diameter of the pellet is determined by the size of the hole (e.g. 2-8mm poultry/livestock).
Flip compression ratio recommendations: Higher for aquatic feed, moderate for poultry/livestock.
Wear resistance: Under abrasive conditions hardened steel or alloy dies wear longer.
Hint: Worn dies should be examined and changed frequently to keep efficiency up.
Steam Conditioning and Temperature Control
Pellet durability and digestibility are increased by proper heat treatment:
Ideal conditioning temperature: 70-90 o C (activates natural binders such as starch).
Quality of steam: The dry, saturated steam is preferred; efficiency is lowered by the use of wet steam.
Retention time: Extend steam conditioning retention time to 45–60 seconds for optimal results.The requirements for aqua feed are higher, around 120s-200s.
Solution: Replace it with high-quality steam boiler to ensure conditioning.
Machine Power and Motor Efficiency
Clarify capacity-power relationships with caveats about variable factors.
The production capacity (e.g., 15-250kW) should be equal to the motor power (kW) as appropriate (1-20 T/H).
Over loading will result in strain on the motor and inconsistency of the pellets.
Variable frequency drives (such as VFDs) are energy saving.
Pellet Cooling and Drying Process
Hot pellets are soft and brittle- correct cooling prevents:
Adjust cooling moisture target to 12–13%.Protection by hardening against transportation.
Pellet quality is enhanced by competent cooling systems (counterflow coolers).
Maintenance and Operational Practices
Breakdowns can be avoided by regular lubrication of bearings and rollers.
Add specific maintenance intervals and safety measures for operational accuracy.
Maintenance of the pellet mill: cleaning of the pellet mill will avoid material build up and corrosion.
Proper adjustments and trouble shooting is ensured through operator training.
