Preventing Roaster Fan Failure and Protecting Product Quality in Industrial Bakery Operations

A high-capacity industrial bakery implemented Industrial Matrix
condition monitoring within the AI Suite™ ecosystem to safeguard
the performance of its roaster circulation fan, a critical asset
responsible for consistent roasting temperature and airflow. 
Early detection of imbalance and bearing deterioration enabled a
controlled replacement during planned downtime, resulting in zero
unplanned stoppage and approximately $8,300 in cost avoidance,
while stabilizing product quality.

The Challenge

The roaster circulation fan operates under intense conditions:

High temperature
Continuous duty cycles
Exposure to debris
Demanding food-safety and HACCP controls

When imbalance or bearing wear occurs, risks include:

Unscheduled downtime costing $4,000–$6,000 per hour
Inconsistent roasting temperatures and damaged product batches
Escalating energy consumption
Limited maintenance flexibility

The bakery required a predictive maintenance system capable of detecting early mechanical degradation before it impacted throughput or quality.

The Solution

Wireless vibration and temperature sensors were installed on the roaster’s circulation fan and connected into the Industrial Matrix AI Suite™ ecosystem.

This delivered:

Continuous monitoring of vibration velocity and frequency patterns
Early detection of imbalance and bearing wear
Automated anomaly alerts for trending deterioration
Expert validation from Industrial Matrix reliability specialists
A scheduled, controlled intervention instead of an emergency shutdown

Data-driven decision-making became central to roaster reliability.

Findings & Action Plan

Phase	Insight	Action	Result
Detection	December 22 - Sudden velocity spike indicating imbalance and bearing stress.Gradual rise in vibration amplitude over two weeks, followed by a rapid spike.	AI alert verified by Industrial Matrix experts.	Early identification of developing failure.
Diagnosis	Rising vibration acceleration confirmed progressive deterioration.	Recommendation for proactive mechanical replacement.	Clear fault source confirmed.
Intervention	January 19 - Fan replaced during scheduled downtime.	Controlled maintenance without production impact.	Vibration levels dropped to a stable baseline.
Verification	Post-replacement data confirmed corrected airflow and mechanical stability.	Continuous monitoring resumed.	Full resolution; risk completely eliminated.
