Advancements in Coffee Manufacturing: From Dehydration Techniques to Quality Control

Abstract

This comprehensive study delves into advanced dehydration techniques and processing technologies in the realm of coffee manufacturing. It offers a comparative analysis of these techniques, specifically focusing on green coffee beans and instant coffee production. The examination encompasses the pivotal steps of grading, roasting, grinding, extraction, and dehydration, which form the core of the coffee manufacturing process. In the context of instant coffee production, two primary dehydration methods, spray-drying and freeze-drying, are scrutinized for their roles in water removal from coffee extracts and slurries and their impact on final product quality and efficiency. This study emphasizes the significance of dehydration processes as the linchpin of manufacturing optimization, considering their prominence in coffee production plants. Furthermore, the research extends to investigate the diverse extraction techniques, additional processes, and critical technologies, such as agglomeration, used in the production of coffee instant powder. Quality control, life cycle analysis, and assurance are scrutinized to provide insights into the overall sustainability of coffee manufacturing. The examination also explores the environmental impact, byproducts, and nuanced properties of coffee powder across different production systems. In essence, this review serves as a valuable resource for industry professionals, researchers, and coffee enthusiasts, offering a holistic understanding of advanced coffee dehydration techniques and their impact on quality, efficiency, and sustainability in the context of both green coffee beans and instant coffee production.
