Digital data driven hybrid sensor-controlled solar dryer

Drying is a critical aspect of many crops like grain, cassava, rice, coffee, beans, fruits (dried for export). In most of these crops, the quality and price depends on the effectiveness of the drying process. Low moisture content is the most important factor in maintaining the quality of the dried crops during storage, as moisture provides an ideal environment for insects and for the development of microorganisms. High moisture content during storage is therefore certain to ruin the taste and appearance. The technologies used for drying in sub Sahara Africa have remained very limited. Different methods have been used in different parts of the country ranging from spreading the crops on the ground or a piece of canvas on the ground, or even in a rented courtyard in a nearby town.

Green Heat together with the department of agricultural and bio systems engineering, Makerere University are addressing the problem of post-harvest losses among farmers by using a digital data driven hybrid sensor controlled solar dryer.

Our biogas digesters, are equipped with a Slurry Separation System (SST), providing an unique waste and biofuel solution.

Our briquettes are formed from dried banana peelings and charcoal dust, a clean and safe fuel alternative to wood and charcoal.

Our solar powered lamps are a safe replacement for hazardous kerosene lighting and provide a power outlet as well for charging small devices.

We provide revolutionary energy solutions and energy consultancy for those without electricity access or seeking an efficient alternative.

Our biogas digesters take a range of animal manure, human waste and organic detritus, converting it into energy and fertilizer.

Our systems convert waste into dry slurry, creating solid fertilizer that can be packaged, stored or applied directly to fields.
