Gravity flow operated small electricity generator retrofit kit to flour mill industry

Flour milling is a grinding process to produce
flour from wheat through comprehensive stages of grinding
and separation. The primary energy is required to provide
power used in grinding of wheat. In wheat milling,
tempering is the process of adding water to wheat before
milling to toughen the bran and mellow the endosperm.
Gravity flow of the wheat is utilized to rotate the dampener
wheel with cups to add water. Low cost gravity flow
operated small electricity generator retrofit kit for dampener
was designed and developed to justify low cost energy
production without expensive solutions. Results of statistical
analysis indicated that there was significant difference
in mean values for voltage, rpm and flow rate at the 95%
probability level. The resulted maximum mechanical power
and measured electrical power were 5.1 W and 4.9 W
respectively at wheat flow rate of 1.6 Kg/s and dampener
wheel rotational velocity of 4.4 rad/s.
