Question

how are grain stored at large and at small scale​

Answer 1

For large scale storage of grain:-

Grains are stored in jute bags or metallic bins. Granaries and silos are used for large-scale storage of grains. This protects the grains from pests like insects and rodents. Vegetable and fruits are stored at a low temperature of −10°C to −18°C in cold storage, where growth of microorganisms is completely inhibited.

For small scale storage of grain:-

The adoption of the small scale metal silo in grain storage instead of the wooden crib (A) can be a great step in reducing post harvest losses of grains in sub-Saharan region. The metal silo usually has one grain inlet (B) which is secured with a rubber band (C) and an outlet (D). The metal silo is usually placed on a wooden pallet (E) to keep it cool
