Omas Flexy Mill is the heart of Luanda’s largest food complex

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.

Omas unveils new logo and brand identity

A new look for Omas Industries

In 2015 we have radically innovated a sector that has been static for almost two centuries. We did this starting from the heart of the mill, presenting the unique Leonardo roller mill. We did a real “milling revolution” which, besides being our pay off, has also been the mantra that has marked our everyday work and that has led us to bring Leonardo roller mill all over the world. 

Today we present ourselves with a new look because we have changed and also our way of designing machines and engineering milling plants has changed.

The evolution of milling art from antiquity to the present day

HOW LEONARDO ELECTRONIC FLEXY MILL REVOLUTIONIZED THE MILLING SECTOR

Milling is the fundamental step in the transformation of wheat into flour with the main objective to separate the endosperm of the caryopsis from the peripheral crushing parts, obtaining the best possible yield. The main product of durum wheat milling is semolina, whereas for soft wheat is flour. The machine currently used for this purpose is the roller mill.

But how did we get here? And how did the Leonardo Roller Mill revolutionize a milling system that has been standing still for years? Let’s discover it together.

FLEXY-MILL, the roller mill that allows you to modify grinding parameters during the grinding process while maintaining the quality of the finished product

In the past years, the consumption of organic grain and/or multigrain bakery products has increased by about 60%.

This development is not the result of institutional campaigns but a spontaneous process.

Durum wheat and grinding diagrams: the 4 factors that influence the grinding process

diagrammi-di-macinazione

During the durum wheat milling, the grinding diagram is well studied in order to obtain the highest percentage of semolina and flour from the incoming wheat.

The semolina, the main product of durum wheat, is collected and separated by machines called seeders. They work using 2 fundamentals, calibration and specific gravity, which are responsible for separating and selecting the semolina grains (although still dirty) coming from the Plansifter.

The good hygiene rules in the milling plant: from the wheat harvesting, to its processing, to the transport of the finished product

igiene-impianto-molitorio

In the food industry more than in other sectors, the quality and the care of the product are essential, considering that any negligence in the processing affects the health of consumers.

The entire wheat grain production chain, from raw material storage to processing and transportation, must be monitored step by step to ensure product quality and health.

This involves the use of a proper hygiene plan of the milling plant and a constant control of the entire production process.

Cereal contamination: how to contain the problem of mycotoxins?

contaminazione-grano-micotossine

In the most general and literal meaning of the term, the mycotoxins are toxic substances produced by fungi, and the first thought related to fungi inevitably evokes the image of Amanita muscaria, the red muscimol mushroom, white-spotted, the most recognizable by children!

It is necessary, however, to open the horizon: it is not only the fungi that produce mycotoxins, because among the fungal species harmful to humans we also find mould. Their nature is parasitic, as all the organisms of the kingdom of living: they infest an host (plant or animal) absorbing part of its nourishment and, through their metabolism, produce some waste substances, the so-called secondary metabolites, which are toxic to many organisms.

2019 CAPEX – Why using the Leonardo Roller mill with Torque Motors (KERS©) can reduce electricity usage and provide up to Millions USD in savings

iceberg

 

Why an iceberg? A roller mill section can be viewed in a similar way to an iceberg! The iceberg helps illustrate the hidden costs of your milling section. The visible area represents the initial equipment purchase and routine service and maintenance.

Hidden beneath is the ever increasing & uncontrollable energy costs. As you’ll note, 90% of overall (machine) cost of ownership is in electricity consumption. Of that, 50% or more of the kWh can be removed from the equation using our KERS System©, increasing net profit margins by 10-20%. In a flour mill, the roller mill section accounts for approximately 65% of the electric bill. ; By reducing energy usage by 50%, it can equal a reduction of 10-15% of labour costs.
