This work aimed to investigate the use of inulin as an alternative binder in fluidized bed agglomeration to improve both acacia gum functional and handling properties. Acacia gum was agglomerated in fluidized bed with inulin solution (18.0% wt/wt) at two different fluidizing air temperature (65 and 85°C) and binder feed rate (1.5 ml/min and 3.0 ml/min). The granule growth kinetics and system stability were monitored by a spatial filter velocimetry probe. The influence of process parameters on process yields and product characteristics: final particle size, wettability, and flowability were also evaluated. We observed an increase in particle size and the agglomerated particles showed a short wetting time, indicating that inulin can be successfully used as an alternative binder adding both nutritional and functional value to the acacia gum. Low binder feed rate provided better system stability and larger particle size.

相思胶流化床附聚：菊粉作为粘合剂和工艺参数分析

这项工作旨在研究菊粉在流化床附聚中作为替代粘合剂的用途，以改善阿拉伯胶的功能和处理性能。在两个不同的流化空气温度（65和85℃）和粘合剂进料速率（1.5 ml / min和3.0 ml / min）下，将菊粉胶与菊粉溶液（18.0％wt / wt）在流化床中团聚。用空间过滤测速仪监测颗粒的生长动力学和系统稳定性。还评估了工艺参数对工艺产量和产品特性的影响：最终粒径，润湿性和流动性。我们观察到粒径增加，并且团聚的颗粒显示出较短的润湿时间，表明菊粉可以成功地用作替代粘合剂，为阿拉伯胶增加营养和功能价值。
