Powdered milk production line

automaticwith dryingwith mixer

Overview
Converting surplus liquid milk into milk powder provides extended shelf life, reduced transport costs and flexibility for downstream processing. Powdered milk is commonly recombined locally or used as an ingredient in dairy products and infant formula. This production line is designed for industrial-scale drying and handling of milk to balance supply and demand across distribution networks.

Technology & advantages
Zhelv (Renox) supplies integrated evaporators and spray dryers engineered for energy-efficient operation and scalable throughput. Design workflows include CFD simulations prior to pilot trials to optimise airflows, heat integration and utility consumption, reducing operating costs and improving process stability.

Powder handling and processing features

• Energy-efficient evaporators and industrial spray dryers for dairy processing
• CFD-based simulation to validate line design before pilot testing
• Powder mixing with vibration screening to ensure particle uniformity
• Automatic sanitary powder conveying systems: vacuum or positive-pressure options
• Wet-mixing modules for infant formula production with variable addition ratios

Applications
Suitable for converting surplus milk into powdered milk for storage, long-distance transport, reconstitution or further processing into dairy ingredients and infant nutrition products. Applicable where liquid milk supply is variable or powdered formats improve logistics and cost-efficiency.
