Designed to meet starch processing requirements

The Merco range of separators are different from conventional multi-purpose nozzle centrifuges, specially developed to meet starch processing requirements. These involve high solids loads and continuous discharge, combined with a need to avoid nozzle blockages.

Merco nozzle centrifuges are now widely used in the starch industry for processes that include primary starch separation, gluten thickening, mill stream thickening and the clarification of middlings. As part of this, they are used for classifying, concentrating and washing solids, and for clarifying liquids that contain relatively high concentrations of solids.

The key feature of the Merco design is a special recirculation system in which solids can be recirculated to the nozzles at the edge of the bowl, at the same time as wash water is added. This unique capability means users can adjust production settings while the system is in operation, simply by varying the nozzle draw-off.

The operator can change the split and the concentration by a simple adjustment of the underflow draw-off valve in the discharge line. This provides a uniquely efficient way to control the separation process by determining exactly how much underflow is to be removed, how much is to be recycled back to the rotor and how much wash water is to be added.

This also makes it possible to use large-diameter nozzles that can deal with variations in feed concentration, as well as helping prevent blockages. This in turn makes the unit more versatile, and makes it easy to vary procedures based on the characteristics of individual feed flows.

Our product range consisting of two models - Merco 32 and Merco 38 - is able to cover all the capacities and business demands at the milling plants.

How to upgrade your Merco H-30 to Merco 32

If you own a machine of older generation Merco H-30 machine, you can easily upgrade it to the latest modification - Merco 32 - by replacing the bowl. It will allow you to increase the plant capacity considerably at a lower capital cost than purchasing a new separator. The installation of a new bowl can be done within one day and at a minimum installation cost.

Merco 32 Capacity Booster: simply replace your Alfa Laval Merco H-30 rotor assembly and feed inlet assembly with our new product Merco 32 rotor assembly and feed inlet assembly. Watch this video to see how easily it can be done at a less investment.
