Bread Inspection

The Challenge:

Our customer wanted to be able to check the colour of every loaf to ensure that the ‘bake time’ was correct. The loaves exit the oven in batches of 12 tins.  The customer wanted to introduce a ‘closed loop’ system whereby consistent under or over baking adjusted the conveyor speed through the oven in order to compensate accordingly.

Our Solution:

A high resolution, colour area scan camera was installed along with diffuse LED lighting. The colour of each loaf in the batch is analysed and based upon statistical trend analysis the control system PLC adjusts the line speed as required. Additionally, individual loafs which fall outside acceptable colour limits are rejected from the line downstream. If more than 5 consecutive loafs are rejected the camera sends an ’emergency’  signal to the PLC so that the operator knows there was a major problem on the line. The system also sends an email to senior management so that they are aware of a major fault, likely to impact production rates.
