Development And Performance Evaluation Of An Integrated Irvingia Spp. (Bush Mango) Nut Extraction And Drying Machine
ABSTRACT
This study focussed on development and
evaluation of an integrated bush mango nut extraction and drying machine. The
machine comprises of two processing operations: seed (nut) extracting and
drying units. The extracting unit consists of the de-fleshing/depulping chamber
and the separating chamber. Powered by a single prime mover, the integration
was achieved through open, crossed belts and pulley arrangement for
synchronized operations. The design capacity of the bush mango hopper was for
60 bush mango fruits. Performance evaluation of the nut extraction efficiency, ๐๐๐ฅ(%)
was carried out at varied fruit moisture contents (fresh and microwaved fruits)
and defleshing speed ranging from 51.8% to 91.8% and 27rpm to 67rpm
respectively. The result indicated maximum extraction efficiency, of 91.67% at
a de-fleshing speed of 27rpm and moisture content of 91.8 % with an average
output of 107.84Kg/hr. It was also found that the de-fleshing time varied
slightly with fruit mass. The dryer demonstrated a capacity of 2.57Kg of
moisture removal in 2 hrs 20 mins, evident from the test conducted. Cost
benefit analysis carried out showed that the machine has a benefit-cost ratio
of 1.28 which is acceptable for investment. Hence, the machine significantly
reduces production time and eliminates drudgery in the production of bush mango
dry nuts.
