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

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.

How is a grain of wheat made? Property, structure and molecular composition

chicco-di-frumento

How is wheat ground? How is flour made? What is the difference between durum wheat and soft wheat? There are lots of questions to be asked when choosing the right products to buy, when it comes to making careful, aware choices about diet.

The starting point, when answering these questions, is to look at the origin of milling wheat: how is it ground and how is the structure of the wheat grain organised?

How to recover the food from cereals damaged by atmospheric agents: grain fermentation for alcohol production

immagine-2

Wholemeal flour can be used for the production of alcohol destined for human consumption.

The distilling industry normally uses cereals with very low specific weight, between 0.65 and 0.72 kg/l. These are foods that have been damaged, probably during cultivation, by the elements leading to compromised or halted development, making it unsuitable for food production.
