Context

Janson de Sailly high school is a historic building, Jules Ferry's first modern high school.

Issues

• A middle school and a high school in the same building: a canteen for the middle school, a canteen for the high school and a single wash-up area in the basement
• Modernize dish sorting and washing by installing conveyors without architectural modification and in compliance with the strict charter of the “Bâtiments de France”

Designing the solution

• A tray drop-off conveyor connected to a first vertical conveyor that passes under the slab, in a footprint of less than 1m2
• A horizontal conveyor suspended from the ceiling is connected to a second vertical conveyor that carries the trays down to the wash-up area
• A third vertical conveyor returns trays from the second canteen to the wash-up area
• At the exit of the two vertical conveyors, a system combines the two lines into one for sorting dishes
