PERFORMANCE EVALUATION OF TWO SYSTEMS FOR MIXING AND PROCESSING FEED ADDITIVES AND CONCENTRATES
Misr Journal of Agricultural Engineering
The main experiments were carried out in a local factory for manufacturing feed additives and concentrates in El-Obour city, Kalubia Governorate to study the effect of some operating parameters on the performance of two mixing units. Experiments were carried out using both big mixer (Buhler) and small mixer (Ribbon) under four different batch sizes, four different mixing times and three different carrier materials. Evaluation of the performance of both mixers was carried out taking into
... taking into consideration the mixer productivity, homogeneity, coefficient of variation, consumed energy and mixing cost. The obtained results reveal t the following: The big mixer is recommended to be used under the following conditions: (Batch size of between 1000 and 1200 kg; mixing time of between 10 and 15 min, and carrier materials of calcium carbonate and corn gluten with ratio of 3:1). The small mixer is recommended to be used under the following conditions: (Batch size of between 200 and 250 kg; mixing time of between 40 and 60 min, and carrier materials of Maltodextrin and sucrose with ratio of 1:1).
