Abstract

A two-in-one machine (a pulverizer and screw press) was developed to digest a steam-treated date palm fruit (Phoenix dactylifera l.) and a screw press specially developed for extraction of juice which could further be processed into date syrup, date jam, binding ingredients for snacks, etc. The prototype design was fabricated at the Nigerian Institute for Oil Palm Research, NIFOR, Benin City, Edo State - Nigeria. The equipment has a capacity of 250 kg fruit/hr with an extraction efficiency of 95 %. A 24 factorial experiment with the following variables: time of sterilization, fruit quantity, water quantity and speed of pulverizer. The effects of these variables on the quantity of juice extracted and their interactions with one another were determined using statistical analysis. Results showed that the effect of each variable was significant (P<0.01). Optimum values for machine speed and time of sterilization were 300 rpm and 90 minutes, respectively. The juice extracted was analyzed for total solids, pH, titratable acidity, mineral contents, total and reducing sugars.
