The results of the above trial clearly show that this type of structure is suitable for the prolonged storage of dry barley. It should be noted that in addition to the low structural cost and ecological advantages of the bunker system, storage losses can be compared very favorably with weight losses in conventional structures.
The major problem encountered was the establish net of temperature gradients in the upper layers of the bulk that promoted moisture migration towards the peak. This resulted in small quantities of mould-damaged grain that had to be separated from the rest of the bulk before unloading. A possible solution to this problem could be by altering the structural configuration of the apex to a flattened area at the peak.
