At United Foods we give special importance to our supply chain management systems. Supply chain management systems and operations play an important role in this particular industry, majorly because the products are highly perishable and thus, reducing lead time at each stage becomes highly important. Similarly, while quality is again a generic issue, it is obviously more critical in the food supply chains. This enables United Foods to be amongst the best rice and sugar exporters from India.
Finally, public policies and regulation have a significant role in influencing food supply chains since the ‘product’ is an essential good, every citizen is a consumer, and a significant percentage of the citizens are producers.
Through our various techniques we ensure efficient operations and supply chain management.
Following is a glimpse of the operations we follow for rice processing that is followed by any world class rice producer:
Rice is cleaned from dust and foreign particles. Classifiers are used to remove straw, sand, stone and paper etc. from the rice, while destoners remove heavy impurities such as stones and glass.
This is a pre-cleaning machine which removes stones from the rice through the principle of oscillating to and fro the particles of different material densities. Pre-cleaned rice is spread on a to and fro oscillating horizontal sieve with air blown from under the sieve. The stones of higher density descend on the sieves and are discharged as waste.
Whitening & Polishing:
During whitening and polishing bran layers are removed from the rice. This not only enhances the appearance of the rice but also increases its shelf life, since the lipids contained in the embryo and the bran layers are highly susceptible to enzymatic and non-enzymatic oxidation. The bran removal is best achieved in several steps to ensure evenly milled rice grains with minimum broken grains and optimum whiteness. The number of passes required depends upon the desired finish and variety of rice. In the whitening process bran is removed by abrasive action. Bran is removed by creating high friction forces between the rice grains. Whitening process results in smooth rice grains with an opaque appearance.
The Silky Polisher is used to obtain high degree of smoothness and shining. It is made from stainless steel non corrosive polishing roll and screw feeder. Due to its unique construction it generates very less broken grains.
Optical inspection is the final quality control and enhancement step in the rice mill. Discoloured grains and optionally chalky kernels are removed to yield a first grade product.
Grading removes broken grains from head rice and sorts it into fractions of different length. Head rice, broken rice and tips are further separated by a sequence of indent cylinders into fractions of different broken sizes and head rice.
Weighing & Packing:
Finally through this machine rice is packed according to buyer’s specification.
