Cohesive powders represent one of the most common challenges in industrial screening processes. When materials tend to agglomerate during storage or handling, they can clog the screening mesh, reducing separation efficiency, increasing downtime, and negatively affecting production continuity.

To address this issue, MLT Cuccolini has developed a range of mesh cleaning systems that operate while the sieving process is taking place, continuously keeping the mesh surface clear without interrupting production.

Drawing on its expertise in the behaviour of cohesive powders during the screening process, MLT Cuccolini identifies the most effective mesh cleaning solution for each application. Depending on the characteristics of the material and the application, different solutions can be used individually or in combination. These include the under-mesh ball system, the under-mesh cylinder system, and the over-mesh triangle system, each designed to improve material flow and prevent powder accumulation on the screening surface.

Among these solutions, the over-mesh triangle system is a modular and removable device that operates mechanically above the mesh. Its action keeps the product flowing continuously, preventing material build-up while preserving the original structure of the vibrating sieve. No machine modifications are required, making the system easy to install and highly adaptable across most of the MLT Cuccolini product range.

The effectiveness of this solution is demonstrated through testing with highly cohesive food flavouring powders, where the cleaning system maintains efficient screening performance even under demanding processing conditions.

Key benefits include compatibility with vibrating sieves of all sizes, easy cleaning, reduced mesh wear, and food-grade compliance upon request. The system has proven its effectiveness in applications across the food and nutraceutical industries.

Rather than applying a standard solution, MLT Cuccolini customizes every mesh cleaning system according to the behaviour of the material and the customer’s production process. Different cleaning technologies can also be combined when required, ensuring the most effective solution for each specific application and delivering consistent screening performance over time.
