3.5 Losses in feed weight
Shortages/ losses can be estimated under following sub heads:
Handling loss
These are the losses due to loading, unloading and transportation from godown to intake hopper or railway siding to godown.
Storage loss
This is due to moisture evaporation, insect infestation, rodent and birds, putrefaction and formation due to bad storage conditions or rancidity.
Production loss
This dust loss is due to various processes, such as conveying, cleaning, mixing and grinding. Leakage of dust through various conveyers and machines can be kept to minimum by using effective packing at all bolted joints and by maintaining effective aspiration system. In grinding, loss occurs due to removal of moisture. Powdered material going out as losses can be minimized by properly maintaining the suction fans and bag filters of the dust extraction systems. However, de-oiled cakes (light material such as rice bran) suffer maximum loss due to grinding.
