Starch separator for starch production

Optimize your starch production with a high-capacity, energy-efficient separator designed for continuous high-speed operations. Perfect for maximizing yield in starch and gluten separation while maintaining reliable uptime and low maintenance.

Separates and Clarifies Starch Products Efficiently

The Merco 32 and Merco 38 nozzle centrifuges from Alfa Laval are engineered specifically for the starch industry, providing a robust solution for challenging separation processes. Designed to handle high solids loads and continuous discharge, these centrifuges utilize a unique recirculation system to efficiently separate, thicken, and clarify starch products such as cornstarch and wheat gluten. With the capability to adjust starch production settings dynamically, the Merco nozzle centrifuges allow for precision control over the process, enhancing yield and purity. The Merco 38 model offers up to a 30% capacity increase and a 25% reduction in power consumption, underscoring its energy-efficient design. Installation is straightforward, and the units are compatible with existing systems for seamless integration. Constructed with durability in mind, they require minimal maintenance, thus ensuring high uptime and a reduced total cost of ownership for starch producers and food processing companies.
