Grain Silos & Storage Bins

Facet Engineering are specialists in the fields of conveyance and process engineering. Included in these specialisations is the design, manufacture, and supply of Grain Silos in South Africa. As to our capacity to do so, we are able to create a grain silo to meet a wide array of specifications.

A silo, or bin, as it is known, is a means by which materials such as grain and other food products are stored and processed. Their usefulness as a storage medium for bulk products, despite their capital intensive nature and relative complexity, means that the usage of grain storage bins and grain silos are common worldwide.

Operation of Grain Silos in South Africa

A grain silo needs to be properly equipped in order to handle the various tasks it is involved in. The grain or product being conveyed is expected to change hands often, and as such, the ownership of the grain is passed along many hands as it is taken from the silo. The grain itself is moved to and from the silo through the use of specially designed conveyor belts and elevation equipment.

This means that a silo needs to be equipped with equipment that is able to accurately measure the quantity of grain or product that is discharged from it. Aside from this, special equipment is also used that allows for grain to be weighed, sampled, and tested while it still remains in the grain silo.

Other Functions of a Grain Silo

Aside from their usage as a measurement tool, and for storage, storage bins and grain silos in South Africa also provide drying capabilities for the agricultural sector. Through the use of a drying system, the process of aeration can be enacted upon wet grain in order to dry it prior to being sold commercially.

Drying via aeration is generally done at the earliest possible point within the grain handling process. Aeration helps to prevent the advent of insects and microbial intrusion, both of which severely degrade the quality of the grain. The drying system also serves to keep the grain at a uniform, low temperature, which assists in drying the grain itself. Running at higher temperatures causes condensation, stimulating microbial growth and insects within the grain silos.

Preparing Grain for Transport to Buyers

Once grain is needed to be moved from the storage bins to be moved to another premises for processing, various actions need to be undertaken beforehand. The first of these is cleaning. Cleaning is done to separate any foreign matter and cracked grain from the rest of the product.

Dust control systems are also essential during this process to prevent dust explosions, which are extremely dangerous and have led to loss of life in past years. Fumigation of the grain also takes place, which involves the use of liquid, gas, or solid pellets to eliminate any surviving pests that may have survived the drying process.

Finally, the storage bins are expected to be able to mix grain in a precise manner. In order to meet grain standards for commercial use, several different loads of them are mixed together. Due to the fact that certain lots of grain have differing characteristics, mixing them makes it possible to reach an “average” in characteristics. This mixing can also be done to meet the specifications of a client, so long as they also meet standards as set out by regulation.
