ABSTRACT

A motorized gingerjuice expression machine (GJEM) was designed and developed using locally available materials, lhe developed machine was tested forjuice yield, juice extraction efficiency, juice extraction loss and juice throughput capacity. Fresh ginger rhizomes at 78.69% moisture content were used tor the test. The results revealed 65.6% moisture content of UGI for three different samples gave an extraction efficiency of 13.71%. 11.12%, 17.14% and the 68% moisture content ol UGII lor three different samples gave an extraction efficiency of 16.61%, 10.36%, 9.92%. lhe highest extraction efficiency among the samples for UGI was 17.14% while that of UGII was 16.61%. this shows there was a better extraction for UGI than UGII. TheJuice yield for UGI for 3 different samples were gotten as follows: 37.1%, 26.93%, 30.48% and the yield for UGI for 3 different samples were gotten as follows: 34.45%, 19.23%, and 20.14%. The highest Juice yield for UGI was 37.1% at moisture content of 65.6% was also better than that of UGII (34.45%) at moisture content 68%. The GJEM was powered by a 3 Hp single-phase electric motor and is affordable. Drying of ginger rhizome deteriorated the oleoresin content and hence, the value and quality of ginger. The motorized gingerjuice expression machine offered an affordable and simple method of processing fresh ginger without drying
