Abstract
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.
Highlights
Quality forage resources as grasslands, fruit juice industry with a cultivated forage crops pulp residue are of great importance for Turkey
Citrus pulps are three very important advantages of such as animal feed; i) primarily to prevent the animals being common to the food of the people, ii) contributing to the production of high quality forage needed in industry and iii) the factors that could make environmental pollution are more effective to prevent damage to the environment by providing the opportunity to use
70% of the total citrus is produced in Çukurova region in Turkey. 95% of grapefruit, lemons 85%, oranges 65%, while 75% still mandarins are grown in this region
Summary
Quality forage resources as grasslands, fruit juice industry with a cultivated forage crops pulp residue are of great importance for Turkey. Rich pulp in terms of a significant amount of the water released as waste material in Turkey cannot be assessed at the desired level for ruminant animals. For making it harmless while they are causing environmental pollution and preventing global warming raided, it has been tried or removed with additional costs. Produced and exposed in the processing of industrial waste processed fruit and vegetables has great importance as a feed ingredient. Citrus fruits (orange, lemon and grapefruit) pulp materials which are exposed in large amounts in Çukurova Region are considered as a model in the present study. The pulp will be removed, and the waste will be turned to a by-product, and it will be dried and processed and it is aimed to determine the possibilities to use as a quality feed source for animal feed
