Recent advancements in industrial liquid mixing have significantly influenced manufacturing efficiency, product quality, and operational sustainability within the detergent industry. This comprehensive review critically evaluates the technological evolution, design optimizations, and industrial applications of an Improved Detergent Mixer in comparison with traditional mixing technologies, including variable speed drive (VSD) mixers, pan mixers, ribbon blenders, and multi-shaft homogenizers. Emphasis is placed on process intensification, energy efficiency, mixing uniformity, and maintenance strategies derived from empirical data and simulation studies. The synthesis includes a wide array of academic resources spanning computational fluid dynamics (CFD), process engineering, industrial case studies, and technical guidelines, offering a robust benchmarking of mixer technologies for detergent formulation. By integrating recent literature and expert technical reports, this review aims to provide a foundational guide for industrial practitioners, equipment designers, and researchers seeking to optimize mixing processes and select the most appropriate mixer configurations for current and future detergent production needs.
