The ALFRA flexible silos are made from a special smooth and inert coated textile to prevent bridging and rat holing and ensure a fast, predictable product supply.
Flexible silos can have a higher production capacity and dosing rates than stainless steel types. They are also easier and cheaper to transport and install than rigid silos.
Outflow speed of particularly poorly flowing materials can be increased by adding air bellows or pneumatic activators to flexible silos and stirring devices to steel silos.
A standard heavy-duty silo deck (walkable and rideable with a pallet truck) can be placed on top of a block of silos. The same modular silo deck is used for flexible and steel silos. An integrated silo lid control can prevent silos from being filled with the wrong product.
Suspended from the top, flexible silos are supported at the regular intervals by form frames to keep the silo shape. Flexible walls together with extra activation substantially improve mass flow behavior of even poor flowing materials. This ensures that the First In materials are also First Out.
The flexible material is ATEX compliant, antistatic and non-conductive (FDA approval possible).
