RICHI MACHINERY has completed shipment of an 8-ton-per-hour premix production line to southern Brazil, supporting regional feed manufacturers focused on high-precision livestock nutrition.

Premix products form the foundation of modern feed formulations, supplying essential vitamins, minerals, and trace elements that represent small inclusion rates but have outsized effects on animal health. Accurate dosing and homogeneous mixing are not optional—they are critical to both animal performance and production economics.

Project Background

Brazil ranks among the world’s leading producers of poultry, pork, and beef, with feed conversion efficiency driving competitiveness in export markets. As formulations become increasingly sophisticated—with specialty additives, enzymes, and precisely balanced trace minerals—demand for high-quality premix facilities continues to grow.

The customer, an established feed manufacturer supplying independent livestock producers, sought a compact yet precise premix system capable of supplying multiple downstream feed mills with consistent nutrient blends. Their existing operation relied on manual addition of micro-ingredients, a method that becomes impractical as product lines diversify and accuracy requirements tighten.

Technical Solution

RICHI provided a specialized premix line incorporating:

• Micro-ingredient storage bins sized for frequent batch changeovers
• High-accuracy weighing modules with electromagnetic force restoration load cells
• Horizontal ribbon mixer engineered for gentle but complete dispersion of fine powders
• Dust-free conveying system incorporating sealed transfers and centralized filtration
• Finished product packing unit with automated bag placement and sealing

The system achieves dosing accuracy within ±0.1 percent of target weight and mixing coefficient of variation below 5 percent—performance levels required for premix operations supplying commercial feed mills.

Special anti-segregation designs prevent separation of fine powders during discharge and transfer. This is particularly important in premix applications where particle size differences between ingredients can lead to stratification and inconsistent nutrient content from bag to bag.

Factory Acceptance and Shipment

Prior to shipment, RICHI conducted full factory acceptance testing witnessed by the customer’s technical staff. Verification included weighing accuracy across the full range of batch sizes, mixer performance through tracer studies, and electrical system stability under simulated operating conditions.

The equipment was packed into four containers and dispatched in January, with installation scheduled for early March. RICHI’s Brazilian service network will provide on-site support during mechanical assembly and control system integration.

Supporting Brazil’s Feed Industry

Once commissioned, the premix plant will supply multiple compound feed lines, enhancing nutritional consistency across livestock operations ranging from poultry integrations to independent swine producers.

This project highlights RICHI’s capability to deliver high-precision feed processing systems for advanced nutrition applications—equipment that operates at tighter tolerances than standard compound feed lines while maintaining the throughput required for commercial viability.
