Abstract

Determination of powder flow behaviour is very important due to the importance of their technological applications. Use of powder flowability data in the design of hoppers is one example. Investigation of the parameters such as particle size, particle size distribution, particle shape, chemical composition, water content and temperature which affect flowability is necessary. Within this work a powder flow tester (PFT) from Brookfield Engineering Laboratories Inc. was employed to assess the flow behaviour of table sugar and rock salt powders having varied size fractions. Flow function, bulk density as well as compressibility of powder samples were tested. The rock salt and table sugar powders were grinded, screened and fractioned into 5 fractions of rock salt and 7 fractions of table sugar powder. The results indicated that increasing particle size led to increasing flowability and bulk density while decreasing compressibility. The threshold particle size range which changes these parameters significantly was notes as 100-200 µm.

Özet

Toz gıdaların üretiminde akış davranışlarının belirlenmesi teknolojik uygulamalar açısından oldukça önemlidir. Toz akış davranışı verilerinin kullanıldığı bir uygulama, depo ünitesi dizaynıdır. Toz gıdaların akış davranışları partikül boyutu, dağılımı, parçacık şekli, parçacıkların kimyasal bileşimi, nem ve sıcaklık gibi parametrelere bağlı olduğundan bu parametrelerin belirlenmesi gereklidir. Bu amaçla kaya tuzu ve sofra şekeri tozlarının farklı partikül boyutlarındaki akış davranışları PFT Toz Akış Test Cihazı kullanılarak belirlenmiştir. Böylece tozların akış fonksiyonu, yığın kütle yoğunluğu ve sıkıştırılabilirlik özelliklerinin partikül boyutuna göre değişimi incelenmiştir. Kaya tuzu ve sofra şekeri örnekleri öğütme ve eleme işlemlerinden geçirilerek tuzdan 5 farklı fraksiyon, şekerden ise 7 farklı fraksiyon elde edilmiştir. Elde edilen sonuçlara göre partikül boyutu büyüdükçe akışkanlığın kolaylaştığı, yoğunluğun arttığı, sıkıştırılabilirliğin ise azaldığı tespit edilmiştir. Bu parametrelerin önemli derecede değişim gösterdiği eşik partikül boyut değerinin 100-200 µm boyut aralığı olduğu tespit edilmiştir.
