The largest agro-industrial complex in Luanda, the capital of Angola, is currently being built. The project include Omas Flexy Mill and covers an area of 200,000 mq2; beside the mill it involves the construction of several sites for the processing of products. The production center will be divided into:

• A plant for processing the meat into charcuterie and long-life derivatives;
• A milk processing plant for the production of soft cheese and yogurt;
• A plant for the production of breakfast biscuits and stuffed cookies;
• A plant for the production of wafers;
• A pasta factory for the production of short and long pasta;
• A 500 TPD milling plant for the production of any type of flour.

Omas was able to win the contract for the milling plant thanks to the high degree of versatility of the Flexy Mill plant, combined with the technical experience gained in the milling field in Africa.

Among the technological assets of this plant, we can remember:

1. The “DD- Direct Drive technology” that drives each grinding roller with a permanent magnet motor, thus allowing the variation of the grinding speeds and the consequent possibility of variation of the grinding diagram in an intuitive and fast way. This technology, Omas’ international patent, allows to grind both soft wheat and to transform it into flour suitable for bakery, pastry and pasta, both durum wheat for the production of thin semolina for the production of high-end pasta.
2. The layout “Economy in Building” which involves the elimination of the engine floor, installing the mill on the ground floor. The building thus reaches a maximum height of 22 meters with a reduction in the costs of construction, foundation and management of the building.
3. The “Dry Scrubbing Technology” an innovative dry grain cleaning treatment. DST allows the deep removal of bacteria, moulds and any other type of external contamination and ensures maximum healthiness and sterilization of flour, to the benefit of the health of the final consumer and a greater shelf-life of flour and derived products.
4. The “KERS – Kinetic Energy Recovery System” that allows the recovery of unused energy during grinding, ensuring the reduction of the energy consumption of the plant and lower CO2 emissions.
5. The absence of transmission belts which, in addition to reducing energy loss, reduces machine and plant downtime and simplifies maintenance.

These technological advantages developed by Omas R&D are combined with two fundamental aspects for the success of a state-of-the-art plant:

• Omas’ service, the customer service that guarantees timely support thanks to the remote connection with the PLC or SCADA plant or thanks to the real time support made possible through the Omas app, using augmented reality technology to guide on-site operators towards troubleshooting.
• The high engineering design at plant level that has allowed to integrate the technical offices of other partners and suppliers in a harmonious way. In particular, we mention Fava for the pasta factory and Polin Forni for biscuits and cookies.

To date, seven food centers in Africa have implemented Flexy Mill technology by Omas, which can reduce electricity costs, ensure maximum grinding flexibility to keep pace with market trends and reduce maintenance and operating costs, to propose finished products at competitive prices.
