Can I use this for liquid dosing?

Yes, when charge and qualified rate are both on a mass basis. Convert volumetric pump settings using the ingredient density at the dosing condition.

Does a lower addition rate always improve mixing?

No. Addition method, ingredient interactions, and agitation also matter. Use the qualified process limit and confirm the actual blend endpoint.

Does final batch mass include the ingredient?

Yes. A 5 wt% target in a 250 kg final batch requires 12.5 kg of this ingredient.

What if the pump operates in pulses?

Check peak rate separately. A compliant average can conceal short high-flow periods that cause flooding, clumping, or other process problems.

Ingredient Addition Rate Calculator

Calculate the average feed rate needed for an ingredient charge. Enter the complete batch mass, recipe percentage, addition time, and qualified maximum dosing rate.

What this calculator does

Calculate the average ingredient feed rate needed to meet a recipe target within your planned addition time.

Formula used

Ingredient charge = final batch mass × formulation target ÷ 100
Addition rate = ingredient charge ÷ addition time
Minimum addition time = ingredient charge ÷ qualified maximum rate
Rate headroom = qualified maximum rate − addition rate

Inputs explained

Final Recipe Batch Mass: Complete batch mass from the approved recipe, including this ingredient.
Ingredient Formulation Target: Ingredient mass percentage of the complete approved batch recipe.
Planned Addition Time: Elapsed time allocated to delivering the complete ingredient charge.
Qualified Maximum Addition Rate: Maximum rate permitted by the validated process and dosing equipment.

How to use the result

Best suited to metering-pump planning, minor ingredient addition scheduling.
Reaction heat, wetting, dust, and dosing pulses are not modeled. The calculated minimum time is a rate constraint, not a validated mixing endpoint.
