Parboiled rice:

It is produced by process of soaking, pressure steaming and drying prior to milling. This helps the grain to absorb most of the vital nutrients from the husk.



Rice milling is the removal of hulls and bran from paddy grains to produce polished rice. A variety of indigenous milling equipment for shelling paddy and polishing rice have been in use from time immemorial.



Food spoilage is due to the action of agents that induce physical and chemical changes like the activities of micro-organisms, attack by mould and metabolic processes. Extensive researches have been carried out on the optimum conditions required, on the nature of storage structures and on the optimum conditions required, on the nature of storage structures and on the nature and extent of changes that occur in the storage of rice. Though storage of dry grains is the rule, under compelling necessity grains are stored under damp conditions also.



Drying is the process that reduces grain moisture content to a safe level for storage. Drying is the most critical operation after harvesting a rice crop. Delays in drying, incomplete drying or ineffective drying will reduce grain quality and result in loss



Grain cleaning after harvest is important as it removes unwanted materials from the grain. Clean grain has a higher value than grain that is contaminated with straws, chaff, weed seeds, soil, rubbish, and other non-grain materials. Grain cleaning will improve the storability of grain, reduce dockage at time of milling, and improve milling output and quality.  Seed cleaning will reduce damage by disease, and improve yields. Following are some general guidelines for cleaning grain and seed.

Post harvest management


Increasing emphasis on higher value farm products to meet the changing diets of urban consumers has focused renewed attention on post-harvest systems, while unacceptably high losses due to poor handling and lack of appropriate infrastructure have reduced economic benefits to small producers.
