3 Ton per hour (75 tons per day) and larger capacities up to 240+ tons per day in respect of maize and wheat mills is developed by ABC Hansen Africa in collaboration with such world class manufacturers as Imas from Turkey, United Milling Systems, Engsko and Skiold of Denmark, AGI, Sweet Manufacturing and Global Industries of the USA, Dynamic Generale of Italy and other renowned manufacturers.

In the case of maize mills, the Sub Sahara region has specific requirements, not nearly consistent for the region, for maize meal where it is often staple diet. In some Central and West African countries casava may form the main staple while maize would still be an important source of carbo hydrates.

In the pre-1990's maize meal was standardized into three distinct qualities by the then South African Maize Board who subsidized maize meal and had to ensure millers. The main two qualities were briefly defined as follows:

Super Maize Meal         Special Maize meal
Fat                            Less than 2%            2% min, 3% max
Fibre                            0.8% max                  1.2% max
Particle size    90% <1,400my              90% > 300my

These qualities form a basis for maize meal throughout the Southern and East African region with major exceptions. The low fat content is achieved by de-germinating maize. In the case of grits used for beer, the fat content becomes even more important.

In some markets, while low fat content maize is desired, a finer particle size is preferred. This usually stems from a region where large scale roller mills ceased to function due to for instance conflict or economic factors, and where hammer milled meal formed the basis of the staple diet and to which the market became accustomed.

Inversely some markets prefer a coarser degerminated meal.

In all cases, meal is preferred with a longer shelf life which is obtained by removed as much of the germ as possible. A lower fibre content is also desired.

The ABC Hansen Africa maize milling systems keep all these factors in mind and design it accordingly.

In the case of large scale wheat milling, ABC Hansen Africa has not only its own expertise, but also that of its global partners at its disposal in the design of large scale milling systems for Africa.

Some equipment used in these systems are shown.
