This is based on the clear evidence of a global shift towards engine and motor driven mechanization systems. The situation is outlined in detail in Farm Machinery, (EOLSS on-line, 2002). Apart from the tractor, the farm machine that has captured the public imagination is the massive combine harvester, a miracle of modern technology.
The overall sequence of operations (Figure 8) is orientated towards protecting post-harvest product quality and minimizing loss due to deterioration occasioned by respiration, microbial activity, insects or rodents. Control of respiration (i.e. conversion of carbohydrates to carbon dioxide and water) in crop products is achieved by temperature reduction, most usually by refrigeration but also by periodic ventilation typically of the cold night air.
