Abstract

The objectives of this research are 1) to find out the proper moisture content and angular velocity of Hammer mill and Burr mill for milling, 2) to select the proper milling machine for certain material and 3) to find out the optimum milling yield. Performance test to both type of soy bean milling machine shows that the greater the angular velocity the more the capacity, the lesser the  fineness modulus and the greater the theoretical energy requirement.  The result of the effect of moisture content ranged at 12% to 20% to performance of both type of milling machine indicate that greater moisture content result in reduced capacity, increased fineness modulus and reduced theoretical energy requirement. Hammer mill gives optimum yield at 4000 rpm of angular velocity and 12% moisture content which are 3.94 kg/h of milling capacity, 2.26 of fineness modulus and 24.16 W of theoretical energy requirement.  Burr mill gives optimum yield at 1200 rpm of angular velocity and 12% moisture content which are 3.40 kg/h of milling capacity, 2.10 of fineness modulus and 26.48 W of theoretical energy requirement.   Key words: milling machine, Burr mill, Hammer mill, rpm,  soybean, moisture content

Abstract

This  research aimed to study the physicochemical characteristics of  water yam flour are due to soaking and drying treatments, as material for edible paper, as a substitute for rice flour in the producing of rice paper (fresh spring roll wrapper).  This study used Randomized  Block Design with two factors: soaking time of 0, 24, and 48 hours; and drying temperature at 40, 50, and 60 °C. The result showed increasing soaking decreased  mucilages, meanwhile increasing soaking time increased swelling power. Moisture content did not differ significantly (p>0.05).  Soaking 24 hours produced the highest final viscosity at all drying temperature. Soaking 24-hour and drying temperature 50 °C treatment could be suggested for producing yam flour and was recommended as  raw material for edible paper processing.Keywords: water yam flour, viscocity, swelling power, physichochemical properties, edible paper
