1.1 Introduction

Rice is the staple food for 65% of the population in India. It is the largest consumed calorie source among the food grains. With a per capita availability of 73.8 kg it meets 31% of the total calorie requirement of the population. India is the second largest producer of rice in the world next to China. The all India area, production, and yield of rice in the year 2001-02 was 44.62 million hectares, 93.08 million tons and 2086 kg/ ha respectively. In India paddy occupies the first place both in area and production. The crop occupies about 37 % of the total cropped area and 44% (2001-02 position) of total production of food grains in India.

Paddy grain is milled either in raw condition or after par-boiling, mostly by single hullers of which over 82,000 are registered in the country. Apart from it there are also a large number of unregistered single hulling units in the country. A good number (60 %) of these are also linked with par-boiling units and sun -drying yards. Most of the tiny hullers of about 250-300 kg/hr capacities are employed for custom milling of paddy. Apart from it double hulling units number over 2,600 units, underrun disc shellers cum cone polishers numbering 5,000 units and rubber roll shellers cum friction polishers numbering over 10,000 units are also present in the country. Further over the years there has been a steady growth of improved rice mills in the country. Most of these have capacities ranging from 2 tons /hr to 10 tons/ hr.

1.4 Need for Improved Rice Mills

The recovery of whole grains in a traditional rice mill using steel hullers for dehusking is around 52-54%. There is excessive loss in the form of coarse and fine brokens. Further loss of large portion of endosperm layers during the dehusking operation further accentuates the problem. Against it, the recovery percent of whole grains in modern rice mills using rubber roll shellers for dehusking operation is around 62-64%. The whole grain recovery percent further increases to 66-68% in case of milling of parboiled paddy. Thus it can be seen that there is an overall
