The Multi-crop thresher (MCT) is a machine that can thresh crops such as rice, maize, wheat, sorghum, barley. The MCT is an improvement on traditional methods which eliminates the need for the toilsome labor and significantly reduces the time required to thresh from three hours to ten minutes per sack of rice. The MCT is designed and implemented by Imara Tech.

Imara Tech aims to make business-to-business sales to partner organizations specializing in the distribution and sales in rural areas. The product is also aimed at entrepreneurs as an additional source of income. Users will be able to purchase MCTs at the fabrication workshops which also act as service centers for machine repairs, showrooms, office space and storage areas. The company intends to provide loans for purchasing the machine.

The Multi-Crop Thresher (MCT) is a throw-in type thresher. This means that crops are fed into the machine from the top. Once they enter the threshing chamber, a rotating drum beats the grains off of the stalks. Large chaff passes through to the exit of the chamber and expelled from the machine, while threshed grain falls through a sieve-like structure called a concave. A fan blows dust and small chaff from the threshed grain, which then leaves the machine through an exit chute to be collected in bags. The thresher is powered by a small 6.5 HP petrol engine. The MCT is made using sheet metal, mild steel, nuts/bolts, welding rods and PPE.
The MCT is designed for portability in the field and around rural settings, it is equipped with two wheels. It also has an indented seat so that it easily fits onto the back of a motorcycle rack.
It is foreseen that the most common modes of failure can be repaired by local technicians. However, Imara Tech plans to use the MCT fabrication workshops as service centers for machine repairs.
Sheet metal, mild steel, nuts/bolts
The Multi-Crop Thresher is designed to thresh crops in a relatively short time compared to traditional threshing methods. It can process 1000 kgs of maize in 24 minutes
Testing by the manufacturer found the MCT to be up to 90 times faster than traditional methods of threshing.
The potential risks associated with this product include grain projectiles from the thresher and minor winding risk.
Entrepreneurs in villages can buy the machine and provide service to smallholder farmers, earning the operator up to 10 USD per hour.
