Abstract

The paper presents the impact of carrageenan addition on rheological characterisation of some hydrocolloid aqueous solutions during stirring with rotational speed changes. Carboxymethyl cellulose, guar gum and xanthan gum were used. Measurements were conducted in a vessel equipped with an anchor stirrer under rotational speed increase and decrease conditions, equivalent to a hysteresis loop rheological test. Rheological parameters were calculated using the power-law equation. It was found that a carrageenan addition generally causes a reduction of liquid apparent viscosity and time-dependent rheological behaviour intensification, with some exceptions.

角叉菜胶添加量对某些水胶体水溶液在长时间搅拌过程中随转速变化的流变特性的影响

本文研究了角叉菜胶添加量对某些水胶体水溶液搅拌过程中随转速变化的流变性能的影响。采用羧甲基纤维素、瓜尔胶和黄原胶。测量是在一个装有锚定搅拌器的容器中进行的，在转速增加和减少的条件下，相当于一个磁滞回线流变试验。利用幂律方程计算了流变参数。研究发现，卡拉胶的加入通常会导致液体表观粘度的降低和随时间变化的流变行为的增强，也有一些例外。

期刊介绍： The content, aim and scope of the proposals should comply with the main subject of the journal, i.e. they should deal with mathematical modelling and/or experimental investigations on momentum, heat and mass transfer, unit processes and operations, integrated processes, biochemical engineering, statics and kinetics of chemical reactions. The experiments and modelling may cover different scales and processes ranging from the molecular phenomena up to production systems. The journal language is grammatically correct British English. Chemical and Process Engineering publishes: i) full text research articles, ii) invited reviews, iii) letters to the editor and iv) short communications, aiming at important new results and/or applications. Each of the publication form is peer-reviewed by at least two independent referees.
