paddy to rice conversion process- COFCO E&T Zhengzhou

Rice, which is harvested each year with 154 million ha, is the most common grain as well as the most popular food in the world. Human consumption accounts for 85% of total production for rice, compared with 72% for wheat and 19% for maize.
In addition, rice is the the most important crop for many of small farmers who grow it throughout the world, and the source of so many landless workers who can make a living from working on farms. In the future, it is necessity that the production of rice continue to grow with the rapidly growing of population.
Preparing the rice field for planting: Rice grows best with bright light and warm temperatures of at least 70°Fahrenheit (approximately 21°Celsius), so a place receiving full sunshine will be the first choice. The planting soil should consists of slightly acidic clay for the best results. There will be a reliable water source supplied and a proper way to drain that water when you ready to harvest.

Paddy transplanting: The traditional way of rice planting, is planting by hand. it is a kind of tedious and labor consuming work. With the development of economy, high-efficiency farming machines-Paddy Transplanter, which is a specialized equipment fitted to transplant rice seedlings onto well-prepared paddy field, free farmers from the tedious planting works. Mechanical transplanting requires considerably less time and labor than manual transplanting. One hectare of land requires 1 person day to establish.
Rice harvesting: Paddy harvesting activities include reaping, stacking, handling, threshing, cleaning, and hauling. Whether harvesting by hands or a machine depends on the size of the operation and the amount of mechanization. However, traditional harvesting activities such as field drying and stacking/piling are not recommended because they can lead to rapid quality deterioration and increased harvest losses. Considering these, Rice Combine Harvesters are popular and accepted by farmers worldwide. They combine all operation: cutting, handling, threshing and cleaning. The driving type rice harvester and crawler type rice harvester are among the best performers rice harvesters during these year.

After the harvesting, there are some other problems troubling farmers that is the poor rice quality. There are many ashes and imporities such as husks, small stones, and short stalks left during harvesting processing. Though rice quantity has increased a lot, the quality still troubled so many farmers. So, the advanced technological rice milling machine were brought to farmers.

Post Production
Fully automatic rice mill plant includes, pre-cleaning, dehusking, paddy separating, milling, grading etc.
Pre-cleaning process consists of two procedures, cleaning and de-stoning. Paddy cleaner is the most essential equipment in a rice mill, as it separates all the impurities like dust, straw, sand, clay and heavy particles of even an uneven sizes from paddy.
Rice dehusking is a process of removing the husk and bran from the paddy rice and producing head white rice grains that are sufficiently milled, free from impurities and contains minimum number of broken grains.
Paddy separating: rice separator separates the unhusked paddy from the brown rice.
◆ Whitening: The Rice milling is the process that helps in removal of hulls and bran's from paddy grains to produce polished rice. White rice is the result of further milling by machines that rub the grains together under pressure. This abrasion removes the bran layers, revealing "white" or "polished" rice. Rice milling machine is used.
◆ Rice grading has several advantages:
(1) immature grains are separated;
(2) a more precise adjustment of the huller is possible, which minimizes breakages;
(3) independent milling of graded lots is possible.
◆ Weighing and bagging : Preparing the milled rice for transport to the customer.
Furthermore, as the increasing cost of conventional fuel and environmental issues, people have turned to clean fuel and energy for living and production, some waste material such as, crop stalk and straw, rice husk, peanut shell, leaves, sawdust, etc.), can be pressed into solid briquettes by using Biomass Briquette, which reduce environmental pollution and recycling for crop wastes.
