Sustainable Production of Biodegradable Microcapsules

在常规工艺中，配方颗粒通常在毫米大小范围内。然而，为了改善传质特性和工艺效率，需要在更小的液滴中进行封装，并结合连续凝固步骤。学生将研究各种可持续生物聚合物/油系统的流变性、包封剂、浓度、界面现象、膜孔大小以及操作条件的影响。将研究胶囊的稳定性以保持包封剂，以了解如何优化产品的保质期。了解在一系列配方应用中对性能的影响，目的是为了获得自由流动的粉末。也可以进行控制释放/保质期测试。

In conventional processing formulated particles are often in the millimetre size range. However, to improve the mass transfer characteristics and process efficiency, encapsulation within smaller droplets is needed in combination with a continuous solidification step. The student will investigate the influence of the rheology of the various sustainable biopolymer/oil systems, encapsulants, concentrations, interfacial phenomena, membrane pore size, as well as operating conditions. Stability of the capsules to keep the encapsulants will be investigated to understand how to optimise the shelf life of the product. Understanding the effects on performance in a range of formulation applications will be examined with the intention to obtain a free-flowing powder. Controlled release / shelf-life tests might be performed too.
