Chocolate Melting Machine - Interface Design (HMI)

Role

UX/UI Designer

Client

Krea Swiss

Industry

Food

Duration

2 Weeks

The Client : KREA Swiss, a manufacturer of precision equipment for food and textile industries.
The Project : A chocolate melting machine built for restaurants and bakeries, requiring precise temperature control for different types of chocolate.
The System : A small, hardware-based screen interface that chefs would use to monitor temperature, adjust settings, and control the machine in real time.
The Challenge : Design the complete UX/UI before physical prototype manufacturing, with no dedicated UX resource, minimal technical specs, and only a rough Excel spreadsheet as reference.
My Role : Design the complete interface and user flow before the physical device was manufactured, defining how the system should look, behave, and respond.

The Environment : Busy kitchens where speed, clarity, and quick decisions matter more than complex controls.
The Complexity : Different chocolate types, varying melting points, and continuous monitoring, all technically detailed processes happening behind the scenes.
The Constraints : A compact hardware display, limited interactions and no physical prototype to test with.
The Challenge : Translate all of this into an interface that feels simple, readable and effortless for chefs.

Workflow First : Mapped real kitchen behavior to understand what chefs need most often and prioritized those actions.
Clarity Over Clutter : Used strong hierarchy, large typography, and minimal layouts to make information readable at a glance.
Fewer Steps : Simplified interactions and reduced taps so common tasks could be completed quickly.
Designing Within Hardware : Collaborated with engineers to ensure every screen worked within display size and technical limitations.
Visual Language : Kept the interface clean, industrial, and distraction-free; matching the professional environment.
