  Business Proposal: Mama Diop Hybrid Solar Dryer Management summary, December 2009 solar dried mango 1. Introduction  Mama Diop   is the name of an enterprise initiated by a Dutch foundation called “Stichting Gambia Project”. The idea is to make local communities benefit by making good use of three specific properties pertaining to many African countries !. the peaks of abundance of arious fruits# usually rotting a$ay aimlessly# %. the abundant a ailability of solar energy# and &. lo$ cost labour. 'rom %((! )uropean demand for dried tropical fruit has been rising at an a erage annual rate of *+# demonstrating that impro ed fruit drying and e,porting capabilities constitute potential means of economic de elopment and po erty alle iation.  Mama Diop  aims at effectuating these opportunities by building means of production in -est Africa# buying the dried products and selling them in )urope. ornerstone of this comprehensi e supply chain approach is the  Hybrid Solar Dryer (HSD)  as described in this document. /o research 0 de elopment is re1uired# merely plain engineering# reducing technical project risk to irtually 2ero. A schedule indicating the re1uired means and time to de elop# build and test a prototype is included. Present status Thirty years of creati e hands3on engineering in )urope plus fi e years of $ood and metal construction in Africa along $ith the de elopment and serial building of relati ely small Solar Dryers in the Gambia ha e gained  Mama Diop  some in aluable African e,perience and kno$3ho$# also regarding 4appropriate management5.The ac1uired insights led to the concept of the 6SD as presented in this document. The ery same dryer $as found to be in demand in 7urkina 'aso and 8ali too9 for a fe$ decades these countries ha e been producing and e,porting dried fruit# mainly :organic; mango. 8ost of it is dried in propane3fuelled 4Atesta5 o ens that ha e become rather obsolete o er time. <ising energy prices and stringent )=3food safety re1uirements add to the loss of competing po$er on the $orld market. /o drying de ice to suit these demands is presently marketed in these countries. A market for the 6SD can safely be presumed in many other African countries. Primary aim >t is  Mama Diop’s  goal to de elop the 6SD and build the prototype in such a $ay that an upgrading3kit for the current Atesta3dryers can be deri ed at the same time# using the same components and 6ybrid Solar technology.

The HSD  Mama Diop’s  6SD is de ised as a modular concept. The basic module $ill re1uire a surface of about ,!( metres and has a capacity of e aporating (( kgs of $ater per %B hrs. >t can be used to dry irtually any crop# from mango to groundnuts. The capacity of the module $ill typically fit the potential of a rural community of !(( 3 &(((. >n an a erage mango season it can dry the yield of about B to C trees. The 6SD3module comprises 3a solar heat collector# reducing fuel consumption93a drying chamber $ith ariable recirculation# minimi2ing the use of energy and optimi2ing product 1uality93a burner using biogas to bridge periods $ithout sunshine93heat e,changers to indirectly heat the air and reuse energy# increasing energy efficiency93a processing space for pre3 and post3drying treatment and for handling and packing dried products9 3a small scale digester# turning %( kgs of daily $aste into biogas# pro iding energy for about !% hours of nighttime drying.3a small P3installation# pro iding electricity for entilation and mo ement in the drying chambers and for lighting the $orking space. 34smart5 drying cycle# adaptable to different crops and?or re1uirements93 The use of $aste heat from the production of electricity for drying purposes is optional9 this could reduce fuel usage for the sole purpose of fruit drying to almost 2ero.3 >n order to minimi2e handling and manipulation of the :bare; product Efor reasons of both cost3efficiency and foodsafetyE# scrupulous attention $ill be paid to $orkflo$ lay3out as $ell as to ergonomics and logistics. 3 Data pro ided by the 8alian 48inistFre de l5Agriculture5 indicate that energy sa ings bet$een (+ and C+ compared to the 4Atesta5 dryers can be e,pected.
