Moringa oleifera is a multipurpose and exceptionally nutritious vegetable tree with a variety of potential uses. It is a sub-tropical species that is known by different regional names as benzolive, drumstick tree, kelor, marango, mulangay, nebeday, saijhan, mooringai and sajna.

The Problem-Drying the Moringa Oleifera leaves without losing nutritional values

Drying the leaves of Morninga Oleifera is the most critical aspect of processing the product. The leaves should be dried in a place protected from sunlight to prevent the loss of vitamins and minerals. Drying the leaves of Morninga Oleifera is the most critical aspect of processing the product. The drying should be done immediately after harvest to prevent the growth of molds and to achieve the best quality of the dried leaves.

In doing so, MAI incurred very high electricity expenses as they used a huge electric oven, which consumed high amount of electricity to produce acceptable dryness of the product .

Also, the drying process took a long time, which was an added problem. Sometimes, MAI also used organic fuels like “Bagasse” or charcoal but such fuels left carbon on the dried leaves. This conventional method forced MAI to maintain high temperature to make the drying time f aster but this increased the risk of damaging or decreasing the quality of the product since high temperature has negative effects.

Drying the Moringa leaves using a desiccant dehumidifier was highly recommended as the conventional hot air drying method, was inefficient when it came to large scale drying. Desiccant dehumidifiers maintain quality of dried products by providing constant dry air at medium temperature all year round. Bry-Air Airgineers helped solve MAI’s problems by installing a desiccant dehumidifier to supply dry air directly to their drying room in a 100% recirculation mode (closed loop). A separate air-conditioning unit was provided by MAI to keep the temperature below 40°C to ensure high product quality while drying.

MAI’s decision to shift to desiccant dehumidification resulted in a 200-300% decrease in drying time, which will boil down to costs savings in electricity, while maintaining high quality of the product. MAI is very satisfied with Bry-Air Dehumidifier‘s performance and the benefits that came along with it.
