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 most important crop for many 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 a necessity that the production of rice continues to grow with a rapidly growing 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 consist 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 specialized equipment fitted to transplant rice seedlings onto a 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 operations: cutting, handling, threshing, and cleaning. The driving type rice harvester and crawler type rice harvester are among the best performers rice harvesters during these years.
After the harvesting, there are some other problems troubling farmers that are the poor rice quality. There are many ashes and impurities 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 was brought to farmers.

Post Production

Fully automatic rice mill plant includes pre-cleaning, dehusking, paddy separating, milling, grading, etc.

milling processing from paddy rice to polished rice

◆ Pre-cleaning

The 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 uneven sizes from paddy.

◆ Rice dehusking

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 a minimum number of broken grains.

◆ Paddy separating

rice separator separates the unhusked paddy from the brown rice.

◆ Whitening

Rice milling is the process that helps in the removal of hulls and brans 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 reduces environmental pollution and recycling for crop wastes.
