The work presents the development of an automated control system for the cold brew coffee preparation process using the slow drip method.
The aim of the study is to create an accessible technical solution to improve the stability, efficiency, and convenience of the brewing process. The object of the study is the extraction process of flavor compounds under the influence of cold water, while the subject is the control system for water supply, brewing time, and sensor-based feedback.
The first chapter outlines the project objectives, analyzes existing solutions, and reviews the historical development of cold brew technology, highlighting technical features of the selected method. The second chapter describes the system architecture, operating principle, and component selection — including microcontroller, sensors, and actuators. The third chapter focuses on system implementation: control algorithm, user interface, circuit diagram, and interaction logic between modules. The fourth chapter includes functionality assessment, efficiency calculations, and analysis of the practical applications of the engineering solutions used.
The developed system automates the cold brew drip process with flow rate, temperature, and liquid level control. It can be used at home, in small coffee shops, in educational labs, or as a basis for further commercial development.
