Powdea FoodSafe Fluidisation bottom for silos

Fluidization method

One of the worst problems with handling powdery materials is their tendency to arch/vault in silos . The powdery ingredient becomes tightly packed when the air is evacuated after the silo filling. In this case, the ingredient becomes poorly flowable, in which case the steady flow from the silo  is completely blocked or weakened. Poor flow also prevents the so-called FIRST IN-FIRST OUT operation, which means that the raw material that comes in first is also the first to leave.

The “fluidity properties” of powdered ingredient can be restored by blowing air into the silo cone in a controlled manner. This is called FLUIDIZATION. It is not necessary to fluidize the entire powder silo, but a very small amount of air is sufficient for the purpose, when it is led to the right place and in the right amount.

For fine particle sized and poorly flowing powders, the fluidization method is the most common and the most effective solution in the market

Powdea fluidisation cone for for silos

Powdea’s fluidisation equipment prevents vaulting of powders in silos and guarantees a controlled and undisturbed discharge  of the silo.

Suitability

• for all powders used by the food and non-food industry
• easy to retrofit into silos and tanks of all sizes and models

Benefits

• production increases – production interruptions caused by vaulting are eliminated
• money is saved – the working time wasted on removing the vault can be used for production
• the quality of the final product improves – the silo empties using the FIFO principle
