by Bentall Rowlands

With the capabilities to design, manufacture, supply, and install storage systems from an extensive range of products, Bentall Rowlands Storage Systems Limited is a leading UK manufacturer in complete storage and processing equipment solutions for the agricultural and industrial markets

They offer a wide range of galvanized steel silos and hoppers, water tanks, catwalks and platforms, material handling equipment, cleaning and grading and weighing and drying systems that are assembled worldwide.

We are extremely proud of the projects that we have undertaken in these geographically challenged areas, proving that whatever the specification, we are sure to provide the most suitable design necessary.”

Moisture levels and unwanted consequences
Getting the moisture levels right in a silo can be challenging but it is essential that the target level be reached within the shortest possible time.

If this does not occur, the results would be the formation of mycotoxin and quality degradation. The main causes of spoilage in stored grain are fungi, insects and mites. Fungi are one of the main consequences of a variety of different moisture contents and temperatures stored in grain.

In order to control this, a principal method known as drying and cooling needs to be put in place. No storage fungi will grow below a moisture content of 14.5 percent but they do continue to grow slowly at near 0°C.

This means that cooling alone is not sufficient but the lower the temperature, the slower the rate of growth.
