Özet: The present study was conducted to develop a drying technology for citrus (orange, lemon and grapefruit) pulps by using scrubber heat source and determination of nutrient values in dried citrus pulps. Scrubber heat source of a calcite production plant was equipped for a drying system which by provided a dried pulp production. Firstly, water content of pulps was reduced to approximately 12% by mechanical press centrifugation. The pulps were then transferred to the vibrio-fluidizer fluid bed. After than pre-dried pulps transferred to rotary drum dryer for three hours and total water content of the pulps was reduced to approximately 8%. Chemical values of powder dried orange, lemon and grapefruit pulps such as DM in the air (926.70, 885.30 and 774.00 g/kg), CP (31.50, 65.70 and 77.00 g/kg), CF (28.50, 12.30 and 14.60 g/kg), EE (204.40, 60.40 and 65.90 g/kg), ME Mcal/kg DM (1.584, 2.492 and 2.356), pH (6.94, 6.96 and 6.93) and percentage of digestibility (61.32, 47.85 and 61.44%) were determined. In conclude, citrus pulps could be used as re-cycled industrial feed in animal nutrition by drying with scrubber heat source dryer.
