In this study, ultrasound either as a pretreatment technique or as an integrated technique was employed to enhance fluidized bed drying of Ascophyllum nodosum, and drying kinetics and dried product quality were assessed. In order to compare technology efficiency and dried product qualities, oven drying and fluidized bed drying (FBD) were employed. The novel drying methods included airborne ultrasound-assisted fluidized bed drying (AUA), ultrasound pre-treatment followed by FBD (USP), and hot water blanching pre-treatment followed byFBD (HWB). Six drying kinetics models were used to describe the drying curves, among which the Page model was the best in fitting USP and AUA. Model by Millidi et al. was employed to describe HWB. Airborne ultrasound in AUA did not reduce energy consumption or drying time, but retained total phenolic content (TPC) as well as colour, and exhibited the highest yield among the novel drying methods. USP and HWB showed lower energy consumption and drying time considerably, but the TPC was the lowest among the studied methods. At the same time, USP dried product exhibited the lowest a_w, followed by HWB and then AUA. This studyalso demonstrated that FBD could be a very practical drying method on Irish brown seaweed, and ultrasound-assisted drying methods may have potential developments in Irish brown seaweed drying process.

在这项研究中，采用超声波作为一种预处理技术或一种综合技术来增强结节菌的流化床干燥。，并评估了干燥动力学和干燥产品质量。为了比较技术效率和干燥产品质量，采用了烤箱干燥和流化床干燥（FBD）。新颖的干燥方法包括：机载超声辅助流化床干燥（AUA），超声预处理，然后进行FBD（USP），以及热水烫漂预处理，然后进行FBD（HWB）。六个干燥动力学模型用于描述干燥曲线，其中Page模型最适合拟合USP和AUA。Millidi等人的模型。用于描述HWB。在AUA中，机载超声波没有降低能耗或干燥时间，但保留了总酚含量（TPC）和颜色，并且在新型干燥方法中表现出最高的收率。USP和HWB显示出较低的能耗和干燥时间，但TPC是研究方法中最低的。同时，USP干品表现最低一个_W¯¯，其次是HWB然后AUA。这项研究还表明，FBD可能是爱尔兰褐色海藻非常实用的干燥方法，而超声辅助干燥方法可能在爱尔兰褐色海藻干燥过程中具有潜在的发展。
