Solution Overview

Problem

Current manual Neapolitan coffee makers require user intervention during water heating and coffee preparation, leading to potential over- or under-extraction issues, and there is a lack of automatic systems for optimizing coffee preparation by percolation, resulting in inconsistent coffee quality and prolonged preparation times.

Innovation Solution

An automatic system with a C-shaped supporting frame, induction heating, robotic elements, and electronic management for timed and temperature-controlled coffee preparation, allowing for remote programming and reduced user intervention, integrating a device for percolation that includes a frustum-shaped water container, coffee powder container with a filter, and a coffee beverage container for optimized coffee brewing.
