Mixing and blending calculators
Calculators for mixing two ingredients to a target concentration: dairy, animal feed, meat, syrups and more. Every result comes with the working, so you can check it.
What a two-ingredient blend calculation is used for
| Field | Typical blend | Balanced on |
|---|---|---|
| Animal and fish feed | Grain with a protein meal | Crude protein % |
| Dairy | Milk with cream or skim | Fat % |
| Meat processing | Lean trim with fat trim | Fat (or lean) % |
| Syrups and juices | Concentrate with water | °Brix (sugar % by mass) |
| Home wine and spirits | Spirit with wine | % alcohol by volume (approximate) |
All of these are the same calculation: the Pearson square calculator takes two concentrations and a target and gives the amounts, with the working shown.
Problems this solves
- "How much of each feed do I need for a 16% protein ration?"
- Square the two feeds' protein values against 16%: see how to use the Pearson square method.
- "How much skim do I add to bring my milk down to 3.5% fat?"
- Square the whole milk and the skim against the target, keeping the whole milk amount fixed: see milk fat standardisation.
- "I have three ingredients."
- Fix the amount of one, or the ratio of two, and the square works again; the method guide shows both with numbers.
Mass or volume?
Blending calculations are exact when concentrations and amounts are both by mass. Volume-based blends, such as alcohol by volume, are approximate because some liquids shrink when mixed. Each calculator states which basis it assumes.
