Generation of trust

A leader in the milling industry of Italy, PolselliI has been manufacturing flour for bread, pizza, and desserts for over a century. The company opted for ELGi air compressors to enhance the quality of its products. Air from the reliable air compressors from ELGi helps them prevent contamination.

The perfect ingredients

Flour is used worldwide to prepare bakery products, snacks, noodles, pizza, pasta, etc. It is obtained by grinding and milling grains. Wheat is among the most popular grains consumed worldwide in the form of flour.

The global wheat flour market is expected to grow at a Compound annual growth rate (CAGR) of 4.02%, reaching US$ 293.5 billion by 2027 from US$ 230.5 billion in 2021. Upsurge in demand for fast and convenient food along with the development in food processing technologies are accredited to the growth of the industry.

Wheat flour is a carbohydrate that provides strength and nutrition. Gluten in wheat flour provides elasticity to the dough and adds texture to baked products. It is a staple for many households as it also helps control blood sugar and cholesterol levels and manage obesity among many other health benefits.

Flatten the world with flour

Founded in Arce, a province in Frosinone, as a small craft business, Polselli has become a world leader in wheat flour production. The company was established in the first half of the 20th century and has become an international leader as it reaches its third generation. The products are meeting the demand across Europe, America, and Asian countries.

Over the century of its existence, the company has expanded its business by bolstering its processes. Covering an area of about 25,000 m2, the grinding installation has a capacity of 350 tons/day. The storage capacity of raw materials is 7,000 tons and about 3,500 tons of finished products. Leveraging technology to monitor products through all stages of production, Polselli offers the best products to meet the diverse demands of the food industry.

3 Ps – Products, Process, and Principles

Polselli is a family-based business driven by the principles of consistently delivering high quality and striving to improve the quality. The Polselli production process involves selecting raw materials and closely monitoring the production process. Innovating to develop new production processes while sticking to traditional methods to ensure the final product has a high level of organoleptic, health, and nutritional value. All products undergo chemical and microbiological tests for control monitoring. It helps analyse and measure the product’s nutritional value while ensuring safety for consumption.

A glitch in the grain

Polselli needs high-quality air processors to ensure contaminant-free production and packing processes across all departments of its plant. From aiding pneumatic services on the factory floor, compressed air also helps increase the shelf life of products. The challenge was deploying an effective air system that could provide oil-free air while maintaining minimal downtime.

Putting quality first

Polselli opted for 2x ELGi AB45 and 1x AB45 V air compressors. Designed specifically for the food industry, the AB Series compressor from ELGi is an oil-free screw air compressor made of materials approved for food-grade applications. The compressor provides high-quality air with ISO8573-1 Class-“0” certification, eliminating oil and moisture entering the process chamber. The unmatched reliability of ELGi air compressors ensures continuous delivery of air, free of microbiological contaminants according to ISO8573-7.

Besides the sturdy design, the compressor uses ELGi’s high-efficiency air ends to comply with safety standards as they are fitted with in-house developed η-V profile rotors.  The AB Series compressor uses a unique water separation by Impact and Centrifugal Action (WSBIC) process. It also has a custom-designed centrifugal type moisture separator to remove 99% water from compressed air and drains it automatically.

The compressor has been sourced from SOL.IM.I., one of ELGi’s channel partners in Italy. Besides the installation, maintenance services of the compressor have been provided by the Channel Partner. The compressor has been running efficiently since its installation in January 2022. The customer has a maintenance contract with the ELGi Channel Partner and any concerns are addressed within 24 hours of the call. Staff from SOL.IM.I. ensures restoration of operations with minimal downtime.

Polselli is a technology-driven organisation that strongly believes in delivering natural and additive-free products. ELGi AB Series air compressors meet the company’s need for sustainable solutions that perform tirelessly to aid all the production and packaging processes. The in-built variable frequency drives (VFD) of the ELGi compressor vary the motor speed to meet the process demand. It helps maintain the right pressure for food processing and reduces energy loss. Roller bearings and closed-loop water circuits have been used to reduce power wastage. The non-contact rotors operate with minimal sound while food-grade approved anodized aluminium housing inhibits microbiological growth. It helps in ensuring compliance with the food industry’s safety standards while also reducing the impact on the environment.

The flour fix

ELGi’s air compressor offered Polselli the following business benefits:

  • High-quality products: Food items must be free of contaminants to ensure they are healthy to consume. Polselli caters to the international market and the products must remain fresh and nutritious throughout the supply chain. High-quality compressed air helps maintain an oil-free and moisture-free environment to retain the powdery form of flour.
  • Minimal downtime: Compressed air is used in all departments of the Polselli flour mill. It is constantly needed to ensure that none of the processes are disrupted. Robust air compressors help maintain a constant flow of compressed air throughout the facility. Maintenance and repair services are provided by ELGi’s Channel Partner, SOL.IM.I. to ensure operations are not disrupted.
  • Cost savings: The food industry has specific requirements of temperature, humidity, and pressure of compressed air in their processes. Polselli has purchased air compressors that meet the specific needs of the flour mill and helps reduce operational costs. The high quality of equipment maximises productivity and the prompt after-sales service minimises expenditure on maintenance.

“ELGi compressors have been an excellent choice for us. Their product is specifically designed to meet our compressed air needs. Stable compressed air helps us maintain the quality we promise to deliver to our customers. It is critical for running our production process. ELGi air compressor is reliable and we haven’t faced any issues until now.
