Manufacture of silos
The stockpiling of products can be done in bags or in hoppers. But when it is necessary to stockpile raw materials in large quantities, we recommend the use of silos because they have the following advantages: they take up less space, facilitate cleaning and require fewer personnel. When combined with automated extraction systems and product feeding to the production line, the need for personnel is further reduced, also reducing the likelihood of human error.
We have the solution to your dry product storage problem. You can choose between a flexible trevira silo for indoor use; a metal silo for indoor use; or, if you need to store floury products outdoors, the metal silo for outdoor use will be the most advisable. The latter can be built in steel with different finishes, and even in stainless steel.
In Prillwitz we offer customized solutions for product storage and feeding to the production line. We have different unloading systems, conveying and sifting for dry products, depending on the product to be processed. We can also provide you with dosers, granulated product mills and state-of-the-art scales that guarantee rigorous production control.
