Project report for Rubber Rice Polisher

In India, A rice huller or rice husker is an agricultural machine used to automate the process of removing the chaff of grains of rice. Throughout history, there have been numerous techniques to hull rice. Traditionally, it would be pounded using some form of mortar and pestle. An early simple machine to do this is a rice pounder. Later even more efficient machinery was developed to hull and polish rice. These machines are most widely developed and used throughout Asia where the most popular type is the Engelberg huller. Rubber rollers may be used to reduce the amount of breakage of the grains, so increasing the yield of the best quality head rice, but the rubber rollers tend to require frequent replacement, which can be a significant drawback. Rubber Rice Polishers or Rubber Brakes have special application in modern rice mill industries for polishing rice. These products are needed in large quantities in modern rice mill plant. The modern rice mill concept has greatly helped in recovering by product i.e. rice bran and has helped to be economically sound. All new plants installed to polish the rice which has adopted this method and is increasing at the rate of 5% per year with higher yield of materials. Rice Rubber Polisher brakes are important part of modern rice milling industry. To polish rice all rice mills need large quantity of rice rubber polisher sticks on regular bases. Rice Rubber Polisher are basically rectangular shaped long sticks and are generally made by natural rubber and Styrene-butadiene rubber as its basic raw material. In the Old model of rice whitening machines, big cones are used to polish the rice & other side rice polishers are used as brakes to stop the rice from flowing out of the machine.

Rice is a staple food in most parts of the country particularly in South, East and North Eastern States. It is also consumed on regular basis in Kashmir and not so regularly in the Northern states of Punjab, Haryana and some parts of Uttar Pradesh. The demand for any food product is always there particularly if it is a regular diet item like Rice or wheat. It is an essential for survival. It is consumed by all the members of the population may be either in fine costly variety by rich or the coarse cheap variety by the poor. The demand for rice will always be there so long the humanity survives. Rising food prices, infrastructure constraints in supply chain, reduction in available agricultural land, high dependency on monsoon, production technology and techniques, poor management and distribution of food commodities, efficiency and transparency of the system, and several other factors are influencing the food security scenario of the country. India needs to invest heavily in the agriculture sector which employs almost 50% of the country’s workforce and contributes 13.7% of the GDP, including the allied sectors. If losses can be prevented by proper post-harvest management system, more grains will be available to feed more people. Due to improved technologies and activities adopted in India, the post- harvest losses of major food grains have been reduced.
