As farmers begin to harvest maize and other cereals, the issue of quality comes up again. One way grain farmers can improve the quality of their produce is by investing in equipment that can remove impurities such as dust, stones, animal droppings and at the same time dry and grade it.

As farmers begin to harvest maize and other cereals, the issue of quality comes up again. One way grain farmers can improve the quality of their produce is by investing in equipment that can remove impurities such as dust, stones, animal droppings and at the same time dry and grade it.

Tonnet Agro Engineering Company Limited, a local agro machinery fabricating company based at Kanyanya, has come up with a machine that farmers can use to clean and grade their grains.

The engine-powered cleaner can process between 700kg-800kg per hour. The machine has four sieve hoppers with a capacity to sieve 100kg at a time.

The sieve gauge is changed according to the size of the grains. They sieve and grade beans, maize, sunflower, rice and groundnuts.

The grains are sorted in three standard sizes. The fourth size is considered too tiny, and is, therefore, discarded as reject. They cleaner is fitted with a fan that sucks out impurities like stones and dust from the grains.

A petrol engine of 3.5-6 horse power(hp) or a single-phase mortar of 1-3hp powers the seed cleaner. The company makes both manually and electronically-operated grain cleaners.
