The Gruber rectangle silo is suitable for storage of grain, corn, oilseeds, and rape. The silo with a conveyor floor, however, is not suitable for pelleted and floury goods. Optionally, a version for seeds is available.
Gruber rectangle silos can be optimally fitted to each building. The individual cells can be up to 10m long, 4m wide and up to 10m high. Single existing supports within the building can be integrated into the silos.
In the version with the conveyor or ventilation floor the silo can be used as a cold air dryer: in the Gruber ventilation silo, grain can be stored with up to 20% moisture content and can be dried by full ventilation combined with "move". The mounted conveyor and ventilation floor can be used for either ventilation or emptying the grain.
Choose Gruber grain storage, for your precious crop is threatened by the following factors:
The rectangle silos by Gruber are available in three versions:
The Gruber rectangle silo is suitable for storage of grain, corn, oilseeds, and rape. The silo with a conveyor floor, however, is not suitable for pelleted and floury goods.
Important arguments for Gruber rectangular silos:
A lot of reasons argue for conveyor-bottom:
The union of ventilation and removal of grain saves conveyors above all at several cells.
The removal by conveyor-bottom is wear-free and handles the grain with care.
plate between botom and grain:
Through the complete separation of ground and grain, no ground-moisture can reach into the storage-grain.
The ventilation is excellent through the big air-exit-surface. Cooling of the grain through winter-ventilation on 10°C is possible and protects from insects.
storage of grain up to 17% humidity:
Because of the good ventilation of the grain, the grain can be enstoraged up to maximum 17% humiditiy. With a ventilation of 50 - 100m³ air capacity / h. /m³ you can conserve the grain and prepare storable.
cold air drying:
With an air-performance of the fan from approximately 100-200m³ per hour per m³ grain, a cold-air drying is possible up to maximum 20% grain-humidity. The maximum filling height is 4-5m. You have to attend to work with a low air humidity as possible. With a heater the air can be heated (max. heating 4°-5°C!). Air-heating via a heater reduces the relative air humidity per °C about 5%. For "cold -air-drying" a relative air humidity of approx. 65-70% is enough.
Through the rectangular and quadratic silos, you take advantage of your expensive building optimally. Finaly you don´t build your hall in round nature.
Often you can save a lot of material by a clever installation of silo cells, because the first cells build parts of further cells.
You don´t waste money because of higher investment costs, but in the course of time it saves a lot of costs for drying and it is very effective against insects and is environment-frindly. Using a conveyor-bottom saves a lot of time by total emptying and is a great assistance.
Advantages of Gruber conveyor bottom in galvanized design:
Elements of rectangel silos:
Consisting of trapez-sheet metal elements, tube legs and stiffening parts.
Possible sheet length:
675 mm, 1000 mm, 1250 mm, 1450 mm, 1500 mm, 1750 mm, 2000 mm, 2225 mm, 2500 mm and 3000 mm.
800 mm or 400 mm.
1600 mm, 1200 mm, 800 mm and 400 mm.
For calculation of the silo-width of the 1st cell you have to add 2x the leg-width, for every further cell each 1x leg-width.
The grain-current when emptying: through the opened outflow-slides the larger-part of the grain flows out independently. The last rest is delivered completely by the conveying-bottom (fan).
The scheme shows like a cell is built. All elements are zinc-coated, without wood-parts and are screwed together. The arrows show the air-current.
