Reduce milling losses, enhance nutritional and organoleptic quality
The "GEM parboiling and flour production for rice" technology is an improved system designed to enhance the parboiling process for rice. This technology introduces a new, advanced design for parboiling equipment, replacing the traditional cast iron drum method that typically exposes processors to harmful emissions, such as carbon monoxide and fine particulate matter. The GEM system utilizes a stainless steel parboiler tank and an enhanced stove design to efficiently steam rice, improving the overall process performance and product quality. It's specifically tailored for small to medium-scale processors in rice-growing regions of Sub-Saharan Africa, where energy and market infrastructures are often underdeveloped. The system's structure and components are easily accessible and can be constructed in remote communities. It significantly reduces the time required for steaming rice compared to conventional methods, achieving substantial improvements in grain quality and efficiency.
This technology is TAAT1 validated.

For Manufacturers
Manufacturing the parboiling technology streamline rice processing, reduce emissions, and optimize resource utilization.
To successfully navigate this market, you need to know where to source the raw material for making the equipment, identify efficient transportation methods, and explore suitable storage facilities.
Your potential customers are : wholesale distributors of input to retailers, and to development projects, government agencies, and NGOs.
Building strong partnerships with wholesale distributor networks is key to the success of your business.
For Resellers
Selling the parboiling technology not only provides a valuable product but also fosters closer engagement with users while simultaneously reducing the significant harvest losses often recorded
To successfully navigate this market, you need to know where to source this equipment (Benin, Cameroon, Ghana and Nigeria), identify efficient transportation methods, and explore suitable storage facilities.
The cost varies depending on the size of the technology. The main expense of the GEM parboiling technology is the installation of a gasification stove, which costs around USD 400. Include the cost of transport and any import duties and taxes.
Your potential customer base is: Farmers, development projects, and farmers cooperatives or associations.
For Users
Using parboiling systems enhance productivity, improve product quality, and contribute to environmental sustainability. Additionally, integrating parboiling technology can lead to cost savings, efficiency gains, and increased market competitiveness in the rice industry.
As key partners you need sellers or fleet managers.
As for the structure of cost : The GEM parboiling technology drastically cuts firewood expenses. Traditional methods cost USD 1.83 per 100 kilograms of rice, while GEM reduces it to just USD 0.64. Installing a gasification stove, costing around USD 400, almost eliminates fuel costs by using rice husk waste for heat generation.

Cleaning and Washing Rough Rice: Clean rough rice with hulls using a winnower and wash it with water. Remove floating grains with fissures and transfer the remaining rice into a clean container, ensuring no sand or gravel from the bottom is included.
Soaking Process: Add 2 parts of water per part of rice by weight. Heat the rice and water mixture to 80°C. Let the mixture sit at ambient temperature for 16 hours.
Steaming the Soaked Rice: Place the soaked rice into a steaming vessel. Position the steaming vessel atop a tank filled with boiling water for 20-25 minutes to allow the vapor to pass through the rice.
Drying Parboiled Rough Rice: Dry the parboiled rice with hulls in the sun until it reaches 18% moisture content. Further dry the rice in the shade until it reaches 14% moisture content. Use a tarpaulin on a cemented surface raised from the ground to dry the rice.
Dehusking and Polishing: Dehusk the parboiled rice using a huller. Polish the rice using a roll mill.
Processing into Flour: Crush and grind the polished grains into a fine powder using a dry rice flour mill.
Packaging: Package the rice flour using paper or plastic bags.
