Abstract Processes in fed-batch using biomass as substrate can be more advantageous, presenting a higher productivity and a lower consumption of enzyme. However, in some cases, processes operating in fed batch may represent a problem in the way the substrate should be fed. In this article, a prototype for solids feeding is developed, which can implement different types of feeding profiles and is controlled through fuzzy logic. Tests considering different feeding profiles for two types of solid materials show that the use of a fuzzy controller provides better results when compared to the system using an On–Off control. The experimental validations of the feeding actions show that the system implementing the fuzzy controller is very effective and can be an alternative in enabling the processes of enzymatic hydrolysis in fed batch that use biomass as the main source for obtaining fermentable sugars.

使用模糊控制的自动固体进料器：用于分批进料生物过程的工具

摘要 使用生物质作为底物的分批补料工艺可能更有利，具有更高的生产力和更低的酶消耗。然而，在某些情况下，以分批补料方式运行的工艺可能会在应送入基材的方式方面存在问题。在本文中，开发了一种固体进料原型，它可以实现不同类型的进料曲线，并通过模糊逻辑进行控制。考虑两种固体材料的不同进料曲线的测试表明，与使用 On-Off 控制的系统相比，使用模糊控制器可提供更好的结果。
