| Summary: | The amount of energy used for the milling process is an important economical consideration. Increasing the
energy usage will increase the operating cost or reduce the mill’s profits. The aim of this study is to reduce the
usage of energy in a break system of a flour milling process. The strategy was to introduce a recycle grinding
circuit in the break system in order to reduce the amount of energy used. The method of determining the amount
of energy used was made through the electrical power used. A comparison of energy usage between the recycle
and conventional processes at break system of flour milling was made. However, this study has limitations and
only concentrated on the calculation of energy used by the main equipments in the break system such as roller
mill, sifter, purifier and bran finisher. With similar target production, 60 tonnes white flour per day, the energy
used in recycle process was found to be 713.30 kW and conventional process was 893.01kW. The results showed
that the conventional process consumed more energy that was 25% higher compared to the recycle process. It
was concluded that the recycle process successfully reduces energy consumption at the break system compared
to the conventional milling process. |
