RICE QUARTERLY

Rice processing
developments in

China
A

s the world's biggest producer and consumer of milled
rice, China and its 1.3 billion people are significantly impacted by developments in rice processing technology.
Deep processing of rice using advanced processing technology and making full use of the rice processing byproducts are important to the sustainable development of China,
which in 2006-07 produced 127.8 million tonnes of milled
rice while consuming approximately the same amount, according to the U.S. Department of Agriculture.

RICE PROCESSING TECHNOLOGY
Classified processing technology, which refers to classifying the paddy into several grades according to different characteristics such as size, bulk density and mechanical properties, is used by many Chinese rice processing enterprises.
Once classified, the rice is processed using different technologies and technological parameters according to the characteristics of each grade. The process includes pre-cleaning

Deep processing using advanced
technology plays important role in
Chinese rice industry
of the raw grain, stone removing and grading before hulling,
whitener milling and finished product packing.
Before milling, a conditioning device is used to treat brown
rice for 20 to 40 minutes according to the water content, quality and temperature of the rice and the processing demand.
Water addition is 0.12% to 0.16%; water content in the upper
layer of brown rice is 16% to 17%; and the water gradient between the upper layer and endosperm is 2% to 3%.
High quality rice processing is tied closely to grinding
