MILL: THE 6 CERTIFICATIONS YOU NEED

08.01.20

Here are the 6 certifications absolutely necessary for your mill, which will help you to ensure the highest quality and a high level of safety. They can also be useful for your feed mill, bakery or pasta factory.

In previous articles we have often pointed out that one of the objectives of a mill is the food safety of flour. It means that a food does not contain substances harmful to man. In addition, another key requirement is the possibility to reconstruct the traceability of the product.

Only a constant technological innovation allows the mill to reach and obtain the certifications.
The flour must comply with ever higher food safety standards, quality characteristics required and rules imposed by compliance with traceability.

 

What is a certification

Before analysing the certifications required for the mill, it is important to understand what is a certification.

A certificate is the certificate issued by an organism outside the company and accredited, which declares a product, a specific process, a service or a Management System in conformity with a Reference Standard.

Reference Standards may be mandatory or voluntary, and shall apply at national (UNI), European (CEN) or international (ISO) levels.

Certifying a product means giving it added value by virtue of certain characteristics possessed by the product itself.

 

The certifications for the mill

Now we come to analyze the 6 fundamental certifications that every mill should get.

Certifications Mill: IFS International Food StandardIFS – International Food Standard

The IFS (International Food Standard) standard is a standard whose purpose is to define food safety requirements. One of the peculiar aspects on which the IFS Standard is based is the Food Defence, whose purpose is to ensure that the product is protected against deliberate or intentional counterfeiting or contamination.

Certifications Mill: BRC Global Standard for Food SafetyBRC – Global Standard for Food Safety

The BRC standard is a globally recognised and validated standard. The main purpose of BRC certification is to define safety and food quality requirements. Thanks to the BRC standard, the certified company is able to demonstrate the robustness of its management system for food safety in the various stages ensuring greater control of its supply network.

Certifications Mill: UNI 10854:1999UNI 10854:1999

This certification is based on the HACCP (Hazard Analysis and critical Control Point) method. This protocol was drawn up to monitor the food safety of astronauts. This concept of food safety has now become a compulsory procedure for all food companies. The HACCP system is needed to minimise the possibility of contamination and to act promptly if food safety is at risk.

Certifications Mill: UNI EN ISO 9001:2015UNI EN ISO 9001:2015

ISO 9001 is one of the most important standards for product safety in the agribusiness. The aim is to control and optimise all aspects of management and production. This means, for the customer, the certainty of buying safe and high quality products, because they are certified and subjected to periodic checks that are carried out by inspectors of the certifying bodies.

Certifications Mill: UNI EN ISO 22005:2008UNI EN ISO 22005:2008

The certification according to the UNI EN ISO 22005:2008 standard is a certification that focuses on the control of the “Traceability system in the agri-food industry”. This standard is correlated to an agreement with the enforced Law, that it previews the presence of an integrated approach of the concepts of traceability along all the row.

Certifications Mill: Certificate of Conformity of Organic Products EuroLeafCertificate of Conformity of Organic Products

The organic certification, recognizable by the EuroLeaf brand, indicates that a food has been obtained through the organic farming only. Essential requirement to obtain it, is the respect of Reg. CE n. 834/07 and 889/08. This certification is obtained from the control carried out by an agency accredited by MIPAF (Ministry of Agriculture and Forestry).

THE MACHINES OF THE MILL: THE PURIFIER

27.11.19

The article describes the machines that make up the mill, in particular the purifier.

In the previous articles, we explained the grinding process (you can read about grinding here). We already talked about the rollermill (you can read about the rollermill here) and the plansichter (you can read about the plansichter here).

We have not discussed, however, about the products of grinding that need further processing. Purifiers process some intermediate fractions selected by the plansichters, which carry out a further selection on a particle size basis. The result is a flour particularly suitable for fresh pasta.

mulino semolatrice mill purifier

The history of the purifier

Cylindrical mills have adopted the purifiers since the second half of the nineteenth century. Those of that time were known as “semolina cleaners” and they worked in different ways.

Principles which will be developed in modern machines were defined only with the “marseillaise cleaner”. The machine was equipped with a fan, which invested the product, driving away lighter fractions, such as bran.

But it needed to work with the surface of the detachments exposed to the environment. The poor hygienic level led to the design of machines closed by a box above the trabatto, equipped with fan.

Therefore, we can trace back to the end of the 800 the birth of machines for the cleaning of the semolina based on the principles still of reference:

  • Grain size selection by stacking frames;
  • Selection based on specific weight and fluid bed functioning.mulino semolatrice mill purifier

The characteristics of the purifier

The purifiers receive the intermediate particle size fractions selected by plansichter. Therefore they are able to make a very accurate selection. The machines also select the flour according to their specific weight. This distinguishes between “clean” groats (the finished product), “dressed” groats (the product to be remilled) and bran.

Let’s see the main characteristics of the purifier:

  • They are binate machines and each side has detaching bodies that vibrate, thanks to the vibrators;
  • The detaching bodies, consisting of stacks superimposed, are surmounted by self-cleaning closed chambers, put in depression by the suction; The air flow invests the frames from the bottom to the top;
  • A self-adjustable feeding system allows a uniform distribution of the product on the sieve;
  • Collecting channels house the heavy flours and send them to further grinding stages, or to silos. The discharges, instead, send the light flours to further grinding stages;
  • Valves of the air control guarantee a constant flow of air on the stacks.mulino semolatrice mill purifier

The process carried out by the purifier in the mill can be summarized in 3 steps:

  • Flour is loaded on the stacks of the first level, which vibrate and arrange meshes with increasing lights;
  • Simultaneously a flow of air crosses the breaks from the bottom to the top;
  • Action of vibration and aspiration causes the flour to become stratified. Machine sucks in the bran fragments and sends the clothed“”semolina to the drains. Pure semolina passes to the levels below, to be purified and sent to the collecting channels.

The first Molitecnica Sud purifier

As for the company reality of Molitecnica Sud, the first purifier built in our factory dates back to 1990. Today we are able to design and build not only high-quality purifier entirely produced in Italy, but also complete mill suitable for every need.

CONFIMI INDUSTRY FOCUS ON CHILE

20.11.19

Confimi Industry Bari focus on Chile and does so through a fruitful collaboration with the Chilean Embassy in Italy and the prochile development agency. Confimi Industry Bari, Bat, Foggia promoter of a meeting in the Chamber of Commerce of Bari in collaboration with the two Chilean institutions, Dialogòi, Production District of the Cultural Industry and ApuliaPromotion.

In a previous article we already talked about the meeting between Molitecnica Sud and Chilean institutions, you can read the article here.

confimi industria cile

Sergio Romero Pizarro, Ambassador of the Republic of Chile to Italy made his debut:

“What we want to do today is not just a presentation of our country. But to talk about concrete possibilities for the common growth of our small and medium-sized industries. We have the resources, of course, but you have the technology, the high-level machinery and the specialization of the employees. We can and must combine our added values. I think it is necessary to create a Chilean consulate here in Bari that can be a safe and reliable environment to facilitate investments and flows of people. We became curious about Apulia because many people came here to discover this land, and moved there definitively”.

Chile is one of the most dynamic countries in Latin America. It currently has 28 free trade agreements with 64 markets worldwide, covering 86.3% of global GDP. Numbers that make it a strategic platform to reach important economic systems such as those Latin American and Asian area to which it directs about 30% of exports, excluding copper.

Sergio Ventricelli, President of Confiscation Bari said:

“We will take our companies to the most technological South American country and we will also open up to tourism. Bari and Puglia have always been committed to trade towards the East. We are guilty of being short-sighted when it comes to the West. That is why I am calling on the regional system today to accompany our companies in seizing this opportunity. We should consider, for example, the opening of an air route to the Chilean capital in view to a first entrepreneurial mission in the next 2020. Strengthening, for Puglia and Chile, a sector that is today strategic and already rich in recognition”.

Relations with Chile are worth 1.8€ billion for Italian exports.

The mining and forestry industries (copper and cellulose are strategic for Italian imports) naturally contribute to maintaining leadership positions in the global scenario. Along with 29 product categories including grapes, cherries and fresh blueberries, plums, salmon fillets, trout fillets, sea urchins and seaweed. Two complementary economies, the Italian and Chilean, because when importing raw materials (hazelnuts, walnuts, kiwi, frozen mussels and plywood) responds to the sending of high-value machinery for industrial processing, to which the supply side of logistics, plant engineering and construction. Still cars, medicines and cosmetics, but also paper, corn carton and corn.

Alberto gorgone, a prochile sales representative, explained:

“A composite framework, therefore, whose joint initiatives can promote the development of small and medium-sized enterprises in both countries by exchanging, together with goods and products, also technologies and knowhow in areas of common interest”. Prochile is an institution charged with increasing and diversifying the country’s exports by supporting the internationalization of small and medium-sized enterprises as well as promoting image, innovation and entrepreneurship.confimi industria cile confimi industry chile

THE MACHINES OF THE MILL: THE PLANSICHTER

06.11.19

The article describes the machines that make up the mill, in particular the plansichter.

We have described the cleaning process (you can read about the cleaning here) and grinding the grain (you can read about the cylindrical grinding here and about the stone grinding here). Contrary to what one might think, flour does not come directly from the milling processes, but is obtained thanks to the screening and selection processes, which are carried out in the plansichter.

mulino plansichter mill plansichter

The history of the plansichter

The history of grinding began in the Egyptian era, with the first attempts to sift the products of grinding. So we can trace back to this time the birth of flour as well as the beginning of the history of plansichter.

The evolution of the plansichter continues in the Roman era, when they began to use rotating hexagonal sifter.

In the Middle Ages it was then switched to centrifugal sifter, consisting of an external rotating drum, a metallic net and a counter-rotating, to push the flour thanks to the centrifugal force.

In 1880 when the flat sifter was invented and in 1905 it was equipped with a free oscillation system. The new machine conceived is patented and called “plansichter”.

The characteristics of the plansichter

Let’s see the main components of a plansichter:mulino plansichter

  • Loading handles in flexible fabric for the loading of flour to be screened;
  • Stacks, housed inside the channels contained in the steel case;
  • Channels containing “parcels” of detachments consisting of overlapping sieves and frames;
  • Insulated doors of the channels, to prevent condensation and limit noise;
  • Suspension rods made of fibreglass, are connected to the case on one side, and to the ceiling on the other. They hold the machine suspended and are flanked by metal cables that hold the case in case of accidental breakage;
  • Unloading handles made of flexible fabric that send the waste of the stacks to subsequent processing or to the flour silos.

The plansichter receives the milled products from the mills and selects the various fractions of these flour, through the stacks and the different veils:

  • Rollermills receive the coarsest fractions for the subsequent grinding steps;
  • Purifier receive the semolina and the semolina, of intermediate grain size;
  • Bran finisher receive the cortical fractions, corresponding to the outer layers of the grain, for subsequent processing;
  • Storage silos receive flour.mulino plansichter mill plansichter

In order to carry out these tasks, the detachment is mounted on a frame that has the function of separating the two adjacent detachments and collecting the product passed through the top detachment. Ejectors send the unloaded fraction to subsequent processing, pushing the flours towards the chassis drains. The movement of the ejectors, and their particular shape, equipped with brushes or rungs, allows to keep clean the veils, which would otherwise lose effectiveness remaining clogged.

The first plansichter of Molitecnica Sud

As for the company reality of Molitecnica Sud, the first plansichter built in our factory dates back to 1989. Today we are able to design and build not only high quality plansichter entirely produced in Italy, but also complete plants and suitable for every need.

FOOD 4.0: DIGITISATION OF ENTERPRISES

30.10.19

Help small and medium-sized enterprises to discover and learn about the opportunities of digitisation in the 4.0 Industry. This is the theme behind the meeting in the Chamber of Commerce in Bari, held on 28th October 2019. The event was organized by Confimi Food in collaboration with Schneider Electric.

Today, the use of data in enterprises is often partial. Yet, as soon as you implement a process of valorization of all business data, starting from an overview of all sources, the data becomes a “business carrier”, which defines business strategies.

Underlying this development is a digitisation process that allows SMEs to remain competitive in increasingly dynamic and fast markets.

In the course of the meeting these themes were explored with a focus on the case studies of companies that have already digitized, taking advantage of the incentives 4.0 Enterprise and the advantages obtained.

THE MACHINES OF THE MILL: THE ROLLERMILL

16.10.19

The article describes the machines that make up the mill, in particular the rollermill.

We have already talked about cylindrical grinding (you can read about cylindrical grinding here). This process allows you to break the grain of wheat, sift the product and regrind it to obtain the flour. The machine used for the breakage and the regrind is called a rollermill.

mulino laminatoio mill rollermill

The history of the rollermill

In ancient times, alternative grinding systems to stone grinding (you can read about stone grinding here), such as the rollermill, were developed.

The first news of an iron machine that could grind wheat goes back to the time of the Emperor Charles V of Spain. In 1500 he ordered the construction of grinding rollers equipped machines.

But only after 150 years machines with two grinding rollers, similar to the current rolling mills, were born. These machineries were able to crush grain.

The efficiency and the qualitative performance of the milling on several passages was realized. This gave a great boost to the milling evolution reaching its current characteristics around 1870.

Rollermill’s characteristics

It can be seen that these machines have maintained some characteristics unchanged for about 150 years:

mulino laminatoio mill rollermill

  • The rolling mills are topped by a transparent bell through which the grinding product is loaded. It allows an immediate visual inspection of the product to be processed;
  • The grinding product is sent to the pair of grinding rollers using feeding rollers. They ensure a regular dosing of the product;
  • Each rollermill contains 2 pairs of rollers;
  • The rollers are carved for the first grinding passages and smooth in the regrinding passages;
  • The rollers that make up each pair are counterrotating, and they move with differentiated speed. This is because for a correct grinding it is necessary, not only to crush, but also to break and stretch the grain of wheat;
  • The rollers are enclosed in a metal frame that prevents the entry of unwanted elements;
  • Distance between grinding rollers is adjusted by a lever system;
  • The collection hopper collects the freshly ground product.

Modern rolling mills offer essential improvements compared to those of the past:

  • Level sensors electronically adjust the speed of feeding rollers, depending on the amount of product in the bell;
  • Increased hygiene level thanks to the elimination of wood and glass elements and geared transmissions in oil bath. Also due to the introduction of scrapers that keep the surface of the rollers clean;

The first Molitecnica Sud rollermill

Regarding Molitecnica Sud business reality, the first rollermill built in our establishment dates back to 2005. Today we are able to design and build not only high quality rollermills, entirely produced in Italy, but also complete grinding plants, suitable for every need.

HOW THE MILL WORKS: STONE GRINDING

02.10.19

The article describes how a mill works, in particular the stone grinding. We have already explained the grain selection and the grain cleaning (you can read the dedicated article here) and illustrated how the cylinder grinding takes place (you can read the dedicated article here).

mulino macinazione a pietra mill stone grinding

The history of grinding

From the earliest times the ancient farmers crushed the grains by means of mortars and then between two stones. Until, in the year 1000 b.C. approximately, it succeeded in giving the millstones a rational shape.

The use of hydraulic force, wind and steam propulsion represented the revolution of this art. At the end of the 18th century the millstones were powered by “batteries” by hydraulic turbines or steam engines. Subsequently also the auxiliary machines were “motorized”, so the dampeners, the elevators and the plansichter appeared.

The refinement of the plansichter revealed the limit of the stone grinding. That is to treat all the grain fractions in the same way, regardless of the different resistance to grinding. So a few years later, roll mills began to take hold.

mulino macinazione a pietra mill stone grinding

The functioning of the stone grinding

Stone grinding technology is based on the knowledge from the late 18th century, shortly before the evolution of cylindrical grinding.

A millstone consists of two horizontal wheels in relative motion one on the other. One of the two wheels is fixed, the other is mobile.

The grain is loaded by means of a hopper to be milled. The grain passes into the space that remains between the two grinding wheels. To facilitate the entry of grain between the two grinding wheels, these have grooves. They also reduce the working surface, increase the air passage and reduce overheating of the product.

The millstone exerts a strong pressure and rubbing action in a single solution. Then the miller adjusts the fineness of the product by approaching or distancing the surface of the two wheels. The flour obtained from stone milling contains the 100% of the grain of wheat. It exceeds the maximum ash limit. Therefore, a selection step is necessary, which takes place in a plansichter. The results are the whole flours and type2” and type1flours.
