Air-recycling aspiration channel for grain cleaning
Optimize grain processing with an innovative air-recycling system that efficiently cleans and removes dust, while reducing energy consumption. Ideal for maintaining high-quality standards in flour production and beyond.

The Air-Recycling Aspiration Channel MVSS from Bühler offers an innovative solution for efficient grain cleaning and dust removal in milling processes. This equipment is distinctive for its use of recirculated air and frequency converters, significantly reducing energy consumption by up to 15% and minimizing fresh air intake by 90% compared to conventional systems. It expertly manages dust and low-density particle removal across various grains, including wheat, rice, and pulses, and is essential for producing high-quality end products like whole wheat flour and basmati rice.
Operating on a continuous, automated basis, the MVSS integrates seamlessly into existing production lines, supporting operations in food processing and grain milling industries. Its adjustable airflow control enables precise separations tailored to specific product needs, achieved through a simple rotary potentiometer or plant control system. This modular system also promises reduced filtration area requirements, enhancing cost-effectiveness and operational efficiency. Built for ease of cleaning and maintenance, the MVSS ensures long-term performance and adaptability across diverse processing applications.
