The Perfect Ingredients for Nutrition

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.

A Glitch in the Grain

POLSELLI needs high-quality air processors to ensure contaminant-free production and packing process 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 oil free 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.
