The Challenge

A large commercial bakery was running three bread production lines at 60% efficiency with manual quality inspection at end-of-line—catching defects only after full production runs. Waste was running at 4.2% of output.

The Solution

Peunier automated the forming, proofing control, oven management, and cooling tunnel across all three lines—integrating inline vision inspection at four critical quality points and deploying real-time OEE monitoring.

Our Approach
01

Line Mapping

Full process mapping of all three lines with time studies, waste point identification, and sensor placement design.

02

PLC & Control Upgrade

Replaced legacy relay logic with Siemens S7-1500 PLCs with HMI touchscreens at each line control station.

03

Vision QC Integration

Installed 4 vision stations per line for shape, size, colour, and surface defect detection with automatic reject gates.

04

OEE Dashboard

Real-time production performance dashboard with shift reporting and automated shift handover summary.
