Engineering studies for processig poultry feather to produce animal feedstuff
Abstract: The effect of four revolving drum speeds (1500,2000,2500 and 3000 r.p.m.), three hammer edge angles (45,60and 90 degree) and two treatment of steam-processed feather (chopped and complete feather) on the power and energy requirements, milling productivity and efficiency were studied. The quality of feather meal during milling the hydrolysed feather was also considered.
Machine productivity and efficiency were increased as the revolving speed of hammer mill increased from 1500 to 3000 r.p.m., and decreased as hammer edge angle increased from 45 to 90 degree, during mill chopped feather comparing with the machine productivity and efficiency by using complete feather.
Increasing mill revolving drum speeds from 1500 to 3000 r. p. m. cause a corresponding increase in the power requirements as, no-load, loaded and useful power for both types of hydrolysed feather under study (chopped and complete). While increasing revolving drum speed from 1500 to 3000 r. p. m. cause a corresponding decrease in the energy consumed (kW .h/ ton) during milling of chopped feathers at any hammer edge angle from 45 to 90 deg.
Total power and energy requirements for chopping and milling feather at 1500 r. p. m. drum speed and 45 deg of hammer edge angled were reduced by about 35.5 % and 41.2 % respectively than that needed when processing complete feathers.
Hydrolysed of chopped feather improved the most of essential and non-essential amino acids comparing with that of complete feathers and this may be produce a meal of high digestibility.
