The effect of postharvest processing machines on damage to maize seed.

The aim of this research was to monitor the influence of the mechanisms on maize seed damage during postharvest processing. Micro- and macro-damage of maize seed were monitored in each operation of the postharvest process. Samples of grain were collected from each mechanism including: incoming unshelled cobs; dehusked cobs; stationary dehusker; drier; the cob mix and shelled grain; and pre-cleaning. The measurements were conducted over a period of 2 years on 3 maize seed hybrids (CE-215, CE-265, TO-455). Cobs coming through the postharvest linkage at moisture contents of 25-38% were damaged from 1.6 to 1.8%, depending upon hybrid. In each postharvest linkage, the critical place was the drier. Maize grain damage increased to 5.8% after drying. The final critical part in the monitored postharvest linkage was the sheller, where an increase in total damage of 12.3% was recorded. Maize grain damage due to impact was partially dependent upon the hardness of the grain.
