Statement of problem
The process of de-pulping
African breadfruit traditionally is slow, tedious and dirty.
It also consumes considerable
amount of water and human energy.
Aim of the study
The aim of the study is to carryout dynamic simulation and
performance evaluation on a continuous process breadfruit de-pulping machine
Objectives of the study
The specific objectives of this
study are:
Solid Modeling
Dynamic Simulation and Finite
Element Analysis (FEA) using Autodesk Inventor software.
Performance evaluation using
mathematical relations
Evaluation of the effects of
speed and fermentation period on de-pulping efficiency using Analysis of variance (ANOVA) as
embedded in Microsoft excel software
Description and working principle
Research Methodology for
dynamic simulation contd.
Components under study
Experiment hypothesis for anaova
Speed has no
significant effect.
Level of fermentation period
has no significant effect.
There is no
significant interaction effect of speed and fermentation period.

Contribution to knowledge
Development
/ mechanization of the process to
de-pulp breadfruit have been attempted.
Using Analysis of Variance
(ANOVA), it is shown that fermentation period of breadfruit has a significant
effect on de-pulping efficiency while speed and interaction between speed and
fermentation period does not have a significant effect on the de-pulping efficiency
of breadfruit.
Conclusion
Dynamic
Simulation
Performance evaluation
Fermentation
period has effect on de-pulping efficiency
Speed
and interaction has no effect
3
days fermented sample has highest efficiency
De-pulping
rate of 26 seeds/sec
