Using solar waves to dry fruits in Mpeketoni

About 40 per cent of fruits grown in Mpeketoni, Lamu County’s food basket, go to waste during the peak season due to over production and low prices, reducing incomes of small holder farmers.

World Concern through the Government of Kenya’s Njaa Marufuku programme is addressing this challenge using a unique, innovative and inexpensive technology.

We facilitated a group of 18 farmers to dry mango fruits using solar energy.

The technology which was first introduced in the country by German Agency for Technical Cooperation (GTZ) uses solar panel, battery and greenhouse-like polythene paper called solar film to capture solar waves for drying fruits. Solar heat is harnessed by a solar panel and transmitted by fans as solar waves through a dryer enclosed with solar film.

Using this innovative technology, World Concern is helping improve incomes of small holder farmers through production of dried fruit snacks for sale. We are also cushioning them from perennial losses arising from lack of ready market and other post-harvest losses.

“We can store mangoes for a longer time and buy plenty of them from our farmers,” said Macharia, Mpeketoni Solar Dryer Group’s secretary. This way, the group will boost incomes of about 500 mango farmers in the area. “We hope to package the dried fruits for sale as a way of adding value,” he added.

Though the project focus was solely mango fruit, the group has gone ahead to dry other fruits and vegetables. “We’re now using the machine to dry tomatoes, sukuma wiki (kales) and cowpeas leaves at the moment,” said the chairman, Mr Geoffrey Mburu.

In this project, World Concern is training farmers on financial management and entrepreneurship, assisting them to set up operations as well as attaining relevant certifications.

Soon, Mpeketoni Solar Drier Self Help group will venture fully into the mango drying enterprise given their high fruit volumes, market demand and nutritious value of the fruit.

“We look forward to building a big business,” said Macharia.

  1. Dear Sir/madam,
    My names are Victor Mulinge from Donyo Sabuk in Kangundo ,Kenya andcurrently doing Mango(400),Banana(600),pawpaw(200),Passion(300) and other crops farming venture as my secondary activity.I got to know about your organization as I was browsing the internet in search of any innovations in farming. Let me first and foremost commend you for your job welldone especially on your Mango value addition project in Kwale in kenya using the new technology value addition on enabling farmers to meet the markets of their farm products without fear of wastes and spoils..

    However,many people have shifted from agriculture, which now make the production to be low while the demand remain high. I have decided to defy this and to date am doing a project on Tissue Culture banana farming which have already done 600 plants where 300 have been mature and harvested,but as for now the tubers are close to 2400 since each has done new shoots at least four each.Curiosity send me in a different direction after knowing you and that have discovered that I can never walk alone and based with what I gathered about your organization we can work
    together if allowed to.

    The value addition of the farming venture is quite good hence the point of doing it in a commercial way for community development.I am asking if there is a way we can work together as we do farming and provide for community development since this is evident from that it can assist many on food,nutrition,healthness and even economic empowerment. I will be very supportive in whatever way as the need may require so as to put things in business. Looking forward for your positive response.
