Milling

The dried paddy is again passed through a secondary cleaning system to remove the foreign particles, stones etc. which were escaped in the preliminary cleaning. The cleaned paddy is de husked in huller mill with the help of the rubber roll hullers. The husk thus separated is either sold or sent to the boiler section for use as fuel. The de husked paddy is passed through table separators and then to the polishing section.

In the polishing section the thick brown layer of the paddy is removed with polishers/whiteners. The thick brown layer thus removed is called bran and will be sold out to the solvent extraction plants as their raw material. The polished rice then passed through sieves to remove broken. The polished rice finally passed through sorters to remove discoloured rice and then sent for packing.

The technology for the plant i.e. captive co-generation power plant and rice mills are conventional and are widely used in the respected industries. As the Government opened the avenues for export of the rice it is used imported machinery and technology.

Captive cogeneration power plant requires machinery and equipment to produce thermal energy and to convert this thermal energy into mechanical energy and to convert the mechanical energy into electrical energy. The standard equipment that are required are high pressure husk fired boiler, back pressure type steam turbine and alternator system. The technology for these items is available indigenously.

The existing technology for rice mill in India is though efficient, cannot compete with the latest technology that is developed by some foreign companies. Even though the basic mechanism and process flow is same, some foreign equipment like Sortex, polishers are being used by the rice milling industry to meet the international standards. In is used plant and machinery and technology provided by various foreign companies like Satake Corporation Ltd., Japan, Cambria., Austria etc. through their franchises in India. The technology provided by the indigenous companies like G. G. Dandekar, Naveen Engineering etc. also will be considered if they can meet the international standards.
