Rice Threshing and Polishing Machines Axial flow thresher and improved quality polishing

Efficient rice threshing and polishing for premium quality grains, boosting income and market access in african communities.

This technology uses special machines to help process rice after it's harvested. The first machine separates the rice from its protective covering. The second machine makes the rice look and taste better by gently polishing it. These machines are easy to move and can be used right in the fields where the rice is grown. They can be powered by generators or solar panels, so they work even in places with no electricity. Made from strong stainless steel, these machines are durable and easy to keep clean. This technology is a big step forward for rice processing, especially for farmers in Sub-Saharan Africa.

Problem

  • High grain losses due to manual threshing methods.
  • Inefficiencies in the traditional polishing process, particularly manual rubbing.
  • Time-consuming and labour-intensive artisanal practices.
  • Difficulty in processing large volumes of rice in communities.
  • Limited adoption of mechanized equipment due to high capital investment and configuration challenges.
  • Lack of access to modern mechanized technologies in many rural regions of Sub-Saharan Africa.

Solution

  • The motorized axial flow threshers employ a turning drum that efficiently separates rice grain from the chaff. This process significantly reduces grain breakage and loss compared to traditional manual methods.
  • The introduction of abrasive polishers using talc or fine dust automates and enhances the polishing process. This ensures a consistent and thorough removal of the bran layers, resulting in higher-quality rice.
  • The mechanized equipment drastically reduces the time and labour required for threshing and polishing. This allows for the processing of larger volumes of rice in a shorter amount of time.
  • The self-contained mobile units can be brought directly to paddy fields, eliminating the need for extensive transportation. This increases the processing capacity and efficiency, especially in communities with high rice production.
  • The technology addresses this by providing cost-effective and easily adaptable mobile units. These units utilize compact generators and solar panels, reducing the capital investment required for mechanized processing.
  • The mobile units are designed to be highly mobile and can be easily transported to even remote rural areas. This enables farmers in these regions to benefit from modern mechanized processing technologies.
