Doubling Capacity, By design

Treating plant expansion and product development as one programme

How a North African bakery group set out to double cake capacity across four lines while developing the products to fill them — and how the same line-design experience has been applied across multi-product cake plants.

The challenge 

 A North African bakery group wanted to double its cake output across four production lines — but doubling capacity was only half the brief. The new lines had to make products the company did not yet fully have: aerated formats such as swiss rolls and cake bars on some lines, and batter products such as poundcake, cupcakes and muffins on others. Buying capacity without developing the products to run on it is how a factory ends up with fast, idle equipment. 

The two questions — "how do we make more?" and "what exactly are we making?" — had to be answered together.

The approach 

Capacity and product development were run as a single programme: 

• Define the products first — For the aerated lines, a cake-bar sponge was specified to a target specific gravity so aeration and structure were locked before equipment was sized. For the batter lines, poundcake, cupcake and muffin formulations were set so the line could be designed around real products, not assumptions. 
• Size the lines to the products — Mixing, depositing, baking and cooling capacity were matched to the defined batters and sponges across all four lines, so throughput targets were grounded in what the products actually needed. 
• Commission against protocols — Dry, wet and full-process commissioning protocols were used to bring each line up in stages, with quality KPIs set against a defined "gold standard" so acceptance was measured, not negotiated.

The result 

The expansion was approached as an integrated programme rather than two disconnected projects — products specified to measurable targets, lines sized to those products, and commissioning verified against explicit KPIs. The outcome the group was building toward was not just more cakes per hour, but more of the right cakes, made to a known standard, on lines that were never waiting for a recipe to catch up.

Key takeaway: Capacity and product development are one programme, not two. Specify the product to a measurable target first, size the line to that product, then commission against KPIs — and new capacity arrives already full of sellable, on-spec product.
