Perforated disc mill for food and chemical processing
Streamline your processing workflow with a versatile solution that excels at transforming solid materials into fine granules, mashes, or purees, efficiently meeting the demands of diverse product formulations.

Processes and Comminutes Fruits, Vegetables, and Chemicals
The Perforated Disc Mill Type EL by Probst & Class is engineered for industrial food, chemical, and cosmetic processing, leveraging German-made high-quality components. It features a knife bar that rotates near a perforated disc, where cutting and impact forces efficiently comminute products. This design accommodates applications such as producing fruit puree, vegetable mash, ground meat, soy milk, and more. The mill’s capacity ranges from 150 to 20,000 kg per hour, depending on material processed. Equipped with interchangeable discs of varying hole diameters, it enables precise customization for different end-products. The Type EL supports seamless integration into existing production lines with its horizontal, in-line operation. Users can utilize their standard B3 motors thanks to the adaptable bearing block system, ensuring compatibility and performance optimization. This equipment complies with FDA standards, offering various mechanical seals, including PTFE lip seals, facilitating installation and maintenance. Optional features include ATEX certification, sterilization capability, and frequency converters for energy efficiency and versatility.
