Silos Metálicos Zaragoza S.L.U products

SIMEZA’s Tanks are used for the storage of liquids. They are designed according to the Euro-Code European norms and are manufactured to withstand stress caused by continuous use, extreme temperatures, high winds and heavy snow. They also offer greater resistance to corrosion through thicker galvanization on the steel sheets.

The filling of silos occurs through the inlet of the central dome of the roof, through gravity piping or with an overhead conveyor requiring safe access to the area. The inspection of the stored product is performed through the inspection hatch installed at roof eave also requiring safe access. Each silo storage plant must be unexceptionally equipped with stairs or ladders which allow for safe and quiet access to the overhead conveyor bridge or to the inspection platforms.

SIMEZA’s manufacturing range includes several standard steel platforms either for inspection purposes or as rest platforms along the ladder to comply with safety regulations.

SIMEZA’s manufacturing range includes 2 types of conveyor bridges: Up to 400 t/h conveyors: The bridges are a modular and open framework type designed to support the dead weight of their structure and conveyor, the product weight, the live load of maintenance operators as well as snow and wind loads according to UNE EN ISO 14222. The bridges are manufactured as standard in several widths from 1200 up to 3000 mm and made of S235 Z600 galvanized steel sheet. They are equipped with handrails on both sides as well as grated floors and are supported by posts directly anchored to the reinforced vertical stiffeners of the silo wall.

The control of the upper level of the stored product allows for proper filling and in general for proper operation of the control system of the silo.

The first parameter which warns of fermentation or infestation of the stored product is its temperature. In order to prevent these problems silos can be equipped with a distributed temperature control system for the product which includes:

The stored products are mainly cereals, wheat, maize, paddy, oilseeds and other grain crops and these organic substances exchange oxygen with the air in the intra-grain spaces. This process is exothermic and generates heat and water in the product, both of which can create problems such as fermentation or clogging. The easiest method to remove the heat and evaporate the water is forced ventilation performed by external electrical fans blowing the outside air or refrigerated air into the stored product.
