Batch Size Calculator — Scale Dairy Recipes

Batch Calculation in Dairy Processing

Scaling recipes is a critical production task. Whether you’re scaling a 200 kg lab trial to a 5,000 kg production batch, or adjusting a recipe for a different vessel size — the principle is the same:

Each ingredient scales linearly with the batch size ratio.

Scaled Quantity = (Ingredient Quantity / Master Batch Size) × Required Batch Size

Use This Calculator For

• Ice cream mix — scaling from development batch to production
• Flavored milk — adjusting recipe for different pasteurizer fill volumes
• Sweetened condensed milk — scaling evaporator batch size
• Dairy beverages — adapting recipes for different batch tank sizes
• Ghee/butter — calculating cream input for required output
• Cheese brine — scaling salt and water quantities

Scaling Best Practices

1. Scale by weight, not volume — weights are more accurate and don’t change with temperature
2. Watch out for non-linear ingredients — stabilizers, emulsifiers, and cultures often don’t scale linearly at very large or very small batches
3. Check equipment limits — ensure your scaled batch fits your vessel with adequate headspace
4. Recalculate minimum agitation speeds — some mixtures require different mixing intensities at scale

Example: Scaling a Flavored Milk Recipe

Master recipe (1000 L):

• Standardized milk: 940 L
• Sugar: 60 kg
• Mango flavor: 0.5 kg
• Stabilizer: 0.3 kg

Target batch: 3,000 L (scaling factor = 3×)
