Different Types of Rice Milling Processes & Methods

The process of removing the husk and bran layers, and producing white rice kernel that is free of impurities is referred to as rice milling. Usually, the three methods of purifying the rice are a one-step process where husk and bran removal are done together, a two-step process where husk and bran are removed separately, and a multistage process in which rice undergoes a series of different rice milling processes & methods.

The two categories in which the rice milling is divided are Village Rice Mills and Commercial Mills. Rice mills which are used for milling paddy of farmers for home consumption are called as village rice mills whereas when the rice is sufficiently milled and all the husks and stones are removed to appeal to the customers, it is known as commercial rice milling. Another objective of commercial mills is to minimize grain breakage.

Multistage Rice milling Process

The paddy is boiled partially, in order to increase its nutritional value, and this process is called parboiling. It reduces breakage and even changes the texture of cooked rice.

Pre-cleaning method: In order to attain high milling recoveries, pre-cleaning of the rice is necessary. If not done properly, the fines in the rice can create dust and can reduce the airflow through the rice grain. De-stoning is done to remove undesired stones present in the rice using a gravity separator or a de-stoner. The process includes passing the rough rice through a series of sieves and a closed-circuit aspiration system.

De-Husking: The process of removing the husk from rice grains is referred to as de-husking. The process includes directing paddy into a pair of rubber rolls, rotating in opposite directions and at different speeds. A shear force is generated on the surface of the hull because of horizontal inward pressure that is applied on rubber rolls. Removing the husk from the brown rice or unhusked paddy is known as husk aspiration.

Paddy Separation: The surface of a rice grain is smooth, whereas the surface of paddy is rough. Paddy Separator uses this difference in texture to spate brown rice from paddy.

Whitening & Polishing: A humidified rice polisher is used to polish the surface of the rice. The factors which determine the extent of whiteness are the radial velocity of the stone wheels, the grid size of the stones, and the external pressure on the outlet chamber of the whitening machine.

Weighing and bagging machines are then used to pack and weigh the rice accurately to be sold in the market.

Conclusion

With so many different rice milling processes & methods, it can be confusing if you don’t have prior knowledge of it. It’s always better to look for Rice Mill Consultants for advice so as to get better results even in the initial stage of the mill.

The Advanced Paddy Drying System

Paddy Drying is the basic process of yielding rice. During the paddy arrival season, the moisture percentage in freshly harvested paddy is 18% and above, the paddy should be dried to bring down the moisture percentage of 14% which is ideal for storage purpose. After the process of parboiling and steaming the moisture increases to 35% which is actually wet paddy. So to reduce the moisture from it various steps are involved such as field drying, sun drying, heated air drying, in-store drying.

If moisture not removed from the paddy, the quality of grain decreases. Instead of sun drying and traditional drying methods, Nextech Solutions offers advancement with Paddy Drying System such as installation & design of paddy dryer machine. This helps in the drying process efficient than traditional drying methods for safe storage.

A Paddy Dryer Machine is designed to suit all the grains. It comes with a blower and furnace digitalized with meters for controlled drying, with the air flow circulation to dry the paddy grains in a closed chamber. The machine works with two chambers or tanks one for filling in and another for discharge. This Paddy dryer Machine can be efficient Paddy Drying Solution for batch type drying and continuous drying processes.

Different Milling Techniques– Modern and Traditional Mills.

Rice has remained the staple food to more than half the humanity since time immemorial despite waves of food revolutions. Covered by two different layers, namely- bran (the inner layer) and husk (outer layer), Rice paddy becomes rice only when the two layers are removed properly through hulling and milling of paddy and hence processing of rice can be termed as the hulling and milling ratio. Production wise India has risen to become the second largest producer of rice in the world (21 percent of global rice production), next only to China. The growth of population exerts more pressure- pushing for higher productivity of crops while a larger quantity of food grain continues to be lost due to inefficient milling processes in the country. Therefore, it calls for a better processing technique of rice to prevent processing loss. Generally, rice kernels are often susceptible to breakage due to inefficient milling processes. Therefore, more efficient milling processes are becoming imperative with Government encouragement and policies so that with better recovery ratio and quality rice kernel production hunger in India is ameliorated after 2030.

The efficiency of grain milling processes denotes three factors-technologies, degree of competition and capacity of utilization each of which Nextechagrisolutions- the leading Rice Mill Consultant in the domestic Food and Grain Industry elevates substantially. Nextechagrisolutions Engineering Solutions Pvt. Ltd.,- India’s leading Rice Mill Project & Rice Mill Plant Manufacturer India & of Rice Mill Machinery Consultants facilitate the transformation from a traditional Rice Mills to a modern one by transferring the expertise and experience of erecting the 360o ecosystem. Nextech Grain Processing & Engineering Solutions Pvt. Ltd. possesses the necessary wherewithal for automating and upgrading of existing Rice Mills to state of the art, automated mill through innovation and automation for customized needs. The quality in terms the rice output’s quality, whiteness, milling degree, grain dimensions is enhanced and enables the manufacturers to fulfill the exacting customer demands on quantity as well as quality parameters to capture market share and ensure greater returns.

Difference Between Traditional & Modern Milling

Generally, rice kernels are often susceptible to breakage and hence hulling and milling ratio is low due to inefficient milling processes. Therefore, modern efficient milling processes that raise productivity are often automated while ensuring a modern product ready for the supermarkets. This not only ensures better recovery ratio & quality rice kernel production but also better returns. The quality of finished rice/polished rice is also dependent on the quality of raw paddy used for conversion, the new technological improvements introduced in rice milling, but the growing demand is making never before demands on rice production. One of Nextech’s specialties is to impart 360o consultancy for the Modernization Of Rice Mills.

Rice Milling Technology– Then & Now

Traditionally, maintaining high quality and output of rice was easy with limited technology, government policies, little investment, miss-management etc. This led to the rejection of many shipped consignments due to poorer than international quality standard. Rice Mill plants were not efficient in terms of energy conservation, maintenance, productivity, and Quality management systems were not employed. The units even lacked testing labs for routine check-ups. Now(automatic and semi-automatic) manufactured and supplied by Japan & Germany are extensively employed and new technologies were introduced including the use of rubber roller technology for husking; Two-stage whitening process; Use of Paddy separators; Old stone disk hullers, vertical cone polishers replaced by emery-coated cylinders etc., Emphasis is now on Skilled operators, use of NUE (Nitrogen Use Efficient) technology and Turbo & extractive milling to speed up the process while saving energy. Nextech Solutions introduces ever more innovations to produce high-quality products for greater returns.
