Design and Analysis of Charcoal Briquette Heat Exchanger for Fruit Drying

Published

on

Introduction to Fruit Drying

According to the United Nations, one-third of the world’s food is wasted annually. The majority of fruit loss occurs during storage or right after harvest. Drying fruit prevents food waste. Drying fruit has a lot of benefits. It can decrease post-harvest waste, increase the commercial value of fruit, add jobs to the local economy, and provide great nutritional value.

Our Community Partner

We have designed an affordable drying system that attempts to optimize drying time and reduce fuel expenditure to allow our community partner, the Teso Women Development Initiative (TEWDI Uganda), to produce attractive, clean-tasting fruit at a profit. TEWDI is based in Soroti, Uganda, and has several small businesses for charcoal briquette, charcoal Makaa cookstove, and fruit drying production.

Activities Conducted

We have evaluated multiple designs from two potential fuel sources: charcoal briquettes and peanut shells. After doing a holistic analysis of different design criteria, we concluded that the charcoal-powered Makaa cookstove heat exchanger (HEX) was the best option. It uses readily available materials and has a familiar user experience. We then designed the HEX around the Makaa cookstove’s dimensions and heat output. In our design, we prioritized the maximization of radiative heat transfer and the minimization of thermodynamic losses. The HEX was then tested for its thermodynamic efficiency.

Evaporative Cooling Shipping Container for Fruit and Vegetable Preservation (Kenya, India)

In developing countries, 30-50% of food produced is lost before it is consumed. Farmers, farmer collectives, and food vendors need an affordable cooling storage solution to increase their produce shelf life. This will not only improve profits, but also provide communities with more access to fresh produce and combat food scarcity and malnourishment. We have helped design fan and power systems of a forced-air evaporative cooling chamber that will address this issue (Figure 1). A fan system forces air through wet evaporative cooling pads, evaporating water and cooling the surrounding air that then flows into a chamber. Our solution will be housed within a 20 foot shipping container and powered by solar panels, such that it will be easily replicable in any region, regardless of access to grid power.
