The theme discussed is “the beginning of a new era“, between digitization, energy efficiency and sustainability.
During the seminar have spoken:
(Giuseppe Bratta, President of Distretto Produttivo La Nuova Energia; Eugenio di Sciascio, Vicemayor of Bari; Riccardo Figliolia, General Secretary of Confimi Industria Puglia; Riccardo Chini, President of Confimi Industria Meccanica Nazionale; Giuseppe Gesmundo, General Secretary Cgil Puglia; Carlo Pellicola, Management director of Molitecnica Sud and President of Confimi Meccanica Puglia).
Riccardo Chini, President of Confimi Industria Meccanica Nazionale:
“Confimi is the association that has been formed to promote and protect the world of manufacturing industry. In this world we work to move forward and moving forward means producing things in a more sustainable way and with respect for environmental resources.
The institutions must play their role as always and must commit themselves to creating the conditions for companies to invest, to finance renewal processes. Industry 4.0 and the circular economy are the two directions in which we need to go. But this requires support in terms of infrastructure and public investment.
The problems are and are partly dictated by exogenous factors. But our industry needs to be supported in evolving, I don’t see a lack of willingness on the part of entrepreneurs to move things forward”.
Carlo Pellicola, Management director of Molitecnica Sud and President of Confimi Meccanica Puglia:
“The event serves to clarify the innovative process of Industry 4.0. We, as Molitecnica, have already started innovation processes with regard to customer service. We hope that in a couple of years we can get this kind of innovation project up and running, so as to facilitate customers in plant management”.
Carlo Pellicola, Management director of Molitecnica Sud and President of Confimi Meccanica Puglia, during the interview for TRM.

Eugenio di Sciascio, Vicemayor of Bari:
“The green new deal is not a cost, but it is an opportunity. We have to work to have increasingly efficient and effective solutions. We must ensure that this is not only environmentally sustainable, but also economically sustainable”.
Alfonso Cialdella, President of Steel Tech:
“Our goal is to make visitors understand that the mechanics must have more and more participation. Especially from students and universities. The objective is also to have the participation of training schools, useful to entrepreneurs and employees. With the new technology of industry 4.0 we need new skills“.
MOLITECNICA SUD AT MECSPE BARI 2019
Molitecnica Sud, together with Gruppo Pellicola, Clustech and Technalia, took part at MECSPE event. The event was held in Bari, at the Nuova Fiera del Levante, from 28 to 30 November 2019.
The new edition of MECSPE covered the Central and South Italian market and the Mediterranean Basin.
It represents a business and networking opportunity, where you can discover the excellence of the whole industry for a smart factory.
600 exhibiting companies in a space of 20,000 m², 54 conferences and workshops, 10 special initiatives.
These were the numbers of MECSPE, a reference event for the manufacturing industry that was held for the first time in Bari. The theme of this edition was innovation and digitization of the company.
Carlo Pellicola has commented
Carlo Pellicola, Management Director of Molitecnica Sud and President of Confimi Meccanica Puglia, commented during the interview for the Gruppo Norba:
“We are here in Bari representing Puglia, with our affiliated companies such as Molitecnica Sud and Gruppo Pellicola. We deal with the agro-food world, but in a metalworking key. (Click here to learn more about Molitecnica Sud).
Today MECSPE talks about industry 4.0. It must help companies in the production process and facilitate customers in our case in plant management.
Taking part in events such as MECSPE, in Italy and abroad, is an opportunity to demonstrate the presence of your company on the market.”
Carlo Pellicola (Management Director of Molitecnica Sud and President of Confimi Meccanica Puglia), during the interview for the Gruppo Norba.
Riccardo Figliolia declared
Among the exhibitors are also Confimi Mechanical Industry, confederation of Italian manufacturing industry and private enterprise. During the event presented a new model of integrated development to be tested in the realities of the territory.
Riccardo figliolia, General Secretary of Confimi Industry Apulia, said to TRM microphones:
“We had to be there at MECSPE Bari, because it is the first edition in this city, since it usually takes place in Parma. It is a showcase for all the Italian mechanical manufacture and in particular for the whole one of the South. Another reason why we could not miss is that the theme of the event is that of innovation.
Innovation is also the main challenge for businesses and we want to help them. In fact, we presented the Confimi plan that committed us to all 2019. It was built with important partners such as Schneider Electric, CSQA and Tempor. We have experimented with this integrated model, throughout Italy starting from the food sector.
For 2020 we will expand to the mechanical industry and integrate to the system also the Universities, starting from the Polytechnic of Bari. We will implement in Puglia an integrated development model where the enterprise is at the centre”

THE MACHINES OF THE MILL: THE PURIFIER
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.
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.
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.
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. To find out more about our machines click here.
CONFIMI INDUSTRY FOCUS ON CHILE
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.
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 know–how 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.
THE MACHINES OF THE MILL: THE PLANSICHTER
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.
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
- 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.
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.

THE MACHINES OF THE MILL: THE ROLLERMILL
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.
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.
It can be seen that these machines have maintained some characteristics unchanged for about 150 years:
- 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 counter–rotating, 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. To find out more about our rolling mills, please consult the data sheet by clicking here, you can also read about our mill plants here.
HOW THE MILL WORKS: STONE GRINDING
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).
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.
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 type “2” and type “1” flours.

HOW THE MILL WORKS: CYLINDRICAL GRINDING
The article describes how the mill works, in particular the cylindrical grinding.
After the grain has been cleaned in the mill (you can read about the cleaning here), the grinding of the grain begins. It is divided into 3 steps:
- Each grain breaks to ecstasize extract the endosperm;
- The sieve separate the flour from the intermediate products;
- It regrind the endosperm to turn it into flour.
The process is performed for a number of steps defined by the grinding diagram. That is the representation of the flow of all the processes to which the various products are subjected inside the mill.
Grinding in the rolling mills
Milling in a cylindrical mill is carried out by rolling mills. These machines have inside them cylinders that go to work on the grain.
Roll mill perform very different functions. They are distinguished by:
- “breakage” roll mills. They are located at the beginning of the process and have the function of breaking the grain. Use striped cylinders whose surfaces never come into contact. These are indicated by the letter B (from the French “Broyage”), followed by a serial number.
- “regrinding” roll mills. They are placed in the successive stages of the process, have the function of regrinding intermediate products. Inside, they use smooth and rounded rollers, whose surfaces can be in contact. It is indicated by the letter C (from the French “Convertissage”), followed by a serial number.
To learn more about grinding plants and mills built by Molitecnica Sud click here.
The grain begins its path in the mill entering the first breaking mill, from which it comes out in the form of a compound. The compressed air transport loads the product on a machine, called plansichter, which classifies the various components making it possible to select the flour.
Selection in the plansichter
The plansichter is a detaching machine whose inside are stacks of sieves superimposed, ordered according to the diagram diagrams. In each stack, the upper cuts have wider mesh veils. While the lower ones have narrower mesh veils.
To learn more about the plansichter made by Molitecnica Sud click here.
The lighter and larger fractions, i.e., the crustal layers, can be switched to storage silos, or they can remain in the process if you want to produce whole meal. While the finest and heaviest fractions are the flour, which comes out of the process to be sent to the silos.
From the intermediate part of the stacking stack, products that need further processing are produced.
These may be sent to rolling mills or grinding machines.

HOW THE MILL WORKS: RECEPTION AND CLEANING
The article describes how the mill works, in particular the reception and cleaning of the grain.
Wheat selection is the first step in milling and also one of the most important because it requires a good knowledge of wheat. Each variety, in fact, has particular characteristics and this means different flours in terms of properties and uses.
Grinding is an ancient process, because the flour produced is the same as always. But there are some determining variables: the choice of the raw material and the sensitivity of the miller who follows and regulates the machinery.
To understand how the mill works, from reception to cleaning, we proceed step by step.
Arrival at the mill
As soon as it arrives at the mill, the grain load is subjected to olfactory and visual controls. In the case of suspected odours or excessive presence of foreign bodies in the cargo, it shall be rejected.
Measurement of specific weight
These initial assessments are followed by the measurement of the specific weight. It determines the milling capacity of the cereal. If the specific weight is below the reference values, the goods are rejected.
Quality analysis of wheat
Then follow the analysis at the entrance that define the quality level of the grain. We detect the protein content and other parameters. If they correspond to the typical values of the variety, the acceptance phase is concluded.
Silage and pre-cleaning
At this point, the grain begins its journey towards silage. During the journey it must pass through a machine that performs the pre-cleaning, making it suitable for the permanence in the storage silos.
The whole stage of reception, unloading and silage of the grain is controlled and recorded by a tracking system. It makes it possible to reconstruct the entire production chain.
Evaluation of rheological values
Analysts grind the samples taken from each accepted load and arrive at the rheological values. They will define the behaviour of flour in the process of dough and leavening.
Cleaning of the grain
Now that the characteristics of the grain silage are known, it is ready to be cleaned from any impurities. The first cleaning process is started, followed by a second cleaning. At their completion the grain enters the final phase of processing, the grinding.
