PROJECT PROFILE ON MODERN RICE MILL

Rice is a vital food material for more than half of the world’s population, the importance of
which as a food crop has been increasing with increase in population. It is estimated that the
rice requirement for Kerala is about 7500 tonnes per day whereas the production within the
state is grossly inadequate to meet the requirement. The productivity of paddy in the State at
the current level is sub optimal, meeting only 15% of the requirement, and the remaining
85% requirement is met from the neighbouring states of Tamil Nadu, Andhra Pradesh and
Modern Rice Mills are scientifically up-to-date units, with most modern plant and
machinery. Rice produced in a Modern Mill would be of superior quality and thereby
finding greater customer acceptance. Further, the bye-product of such Mills, Rice bran, could
find great demand as raw material among solvent Extraction Plants.
At present, the paddy milling capacity available in the State is about 3000-3500 Tons per day
giving an output of only about 2000 Tons of rice per day, leaving a huge gap which is being
met by Public Distribution System (PDS) and by import of paddy/ rice from other states. As
per figures from Rice Mills Owners Association, there are about 125 rice mills operating in
the State, out of which about 50% are modern sophisticated units with Whitener and Color
Sorter machinery and others are partially modernized or upgraded from the traditional Rice
Mills (by incorporating dryer systems). The remaining units are having a capacity to process
only about 10 Tons of paddy per week. Rice Mills in Kerala are meeting only 20% of the
State’s requirements and the balance is met by PDS and from other states. So the Demand-
Supply gap is huge and there is sufficient scope for more Rice Mills.
The manufacturing process employed in a Modern Rice Mill is continuous and fully
automatic, consisting of Paddy Cleaning, Par Boiling, Drying, Milling, Sorting and Packing.
The Cleaning section consists of raw paddy cleaners, de-stoner and dust blowers, where the
dust, mud, stones and immature paddy are removed to make it completely free from the
foreign materials. The next stage is a pre-milling process called Parboiling, which is the
partial cooking of the grain with husk, done to impart the required hardness to paddy grains
so as to withstand the pressure exerted during the Milling process. The parboiled paddy is
taken to the Drying section which consists of the Drying plant, Heat exchanger and Blower.
The steam produced by the boiler is used for drying the paddy in the drier. The drying time can be altered by adjusting the temperature of the drier. When the paddy is sufficiently dry,
it is taken to the Milling section. Milling is the process of removing husk from paddy by
application of force through a rubber roller. Milling section consists of a Rubber Sheller,
Cone Polishers, Bran Blower and Separator, De-stoner and a Vibrator machine. The paddy
husk is collected in a separate room and is used as the fuel for firing the boiler, or sold
loosely for making cattle feed, manure, etc.
There is tremendous potential for marketing Sortex Rice in the State, mainly through
wholesale merchants at Palakkad, Alappuzha, Thrissur, Malappuram, Kozhikode and
Kannur. By setting up a Modern Rice Mill with large capacity, competitive price could be
quoted due to economies of scale. Marketing is not at all a problem once the quality
standards and distribution channels are established. There is also great potential for exports
to Middle East countries, as India is the major exporter of Rice to the Middle East.
The broken rice, rice bran and husk could be sold in domestic market. Rice bran finds good
buyers among solvent extraction units both within and outside Kerala. Rice bran also could
be sold to units manufacturing fodder viz. Milma, Lipton, Godrej, KSE Ltd, Kerala feeds etc,
to name a few.
