tailieunhanh - Physical properties of dates fruits

Date palm (Phoenix dactylifera L.) is a monocotyledon of the family of the Palmae. The date palm is grown in Kutchh region of Gujarat. The physical properties of dates fruits (Variety: Zahidi) are necessary for the design of the equipment to handle, transport, process and storage. In this study some physical properties of dates fruits determined as a function of moisture content namely, dimensions, arithmetic and geometric mean diameter, sphericity, surface area, 1000 unit mass, bulk density, true density, porosity, angle of repose and coefficient of static friction. The average values of length, breadth and thickness of date palm fruit at different moisture content and % (.) were found to be and mm, and mm, and mm respectively. The arithmetic and geometric mean diameter of fresh date fruit ranged from mm and mm respectively. The value of sphericity for different moisture content varied from to . The bulk density varied from 491 to 477 kg/m3 . The true density decreased from 576 to 533 kg/m3 . The porosity varied from to % for the moisture content of and (.). The angle of repose increased from to . It was found that the coefficient of static friction of date fruits varied from (wood surface), (steel surface) and (glass surface). | 2019 8 4 1243-1249 EXCELLENT PUBLISHERS International Journal of Current Microbiology andAppliedSciences ISSN 2319-7706 Volume 8 Number 04 2019 Journal homepage http Original Research Article https Physical Properties of Dates Fruits N1 1 2 1 .1N.
