Emulsified sauces and dressings
Specify oil addition, temperature history, viscosity development and the accepted emulsion after the entire process. A stable laboratory sample does not establish scale-up duty.
High-shear mixing and emulsification
High-shear mixing systems.
Match shear to the product.
Compare batch and inline mixing, ingredient wetting, emulsion quality and recirculation duty before buying a larger food or beverage mixer.
How DPS can scope the process and investment decision.
Start with the business outcome
A high-shear mixing upgrade is useful when representative trials show that wetting, dispersion or emulsion formation limits accepted batches. DPS can coordinate vessel duty, an appropriate specialist mixing package, transfer, instrumentation, cleaning and installation. The objective is repeatable product within a useful cycle, rather than maximum motor power or shear for every recipe.
Agree mixer OEM responsibilities, recipe / ingredient expertise and quality acceptance explicitly. DPS process and integration scope does not imply formulation approval or manufacture of every rotor-stator, homogenizer or vacuum package.
Product and operating requirements: materials, quality and equipment duty.
Functional and protein beverages
Record powder behavior, wetting, hydration and foam. Some ingredients require dispersion energy while others require residence; excessive surface agitation can create another downstream problem.
Sensitive or particulate recipes
Define what should be dispersed and which pieces must remain intact. A shared mixing train may need different routes or operating modes rather than one aggressive setting.
Compare the process sequence, equipment options and interfaces.
Compare mixer position, liquid level and addition sequence over the real working-volume range.
Charge liquidEstablish the required starting level.

Compare operating corrections, retrofit and replacement.
Inspect the installed head, agitator, loop, liquid levels, ingredient addition and cleaning path. Trial operating corrections before assigning the project to a larger motor or replacement head.
Investment boundaryThe preset is a hypothetical intervention in an existing operation. Defined capital scope, separate site additions, owner startup expense and working capital have different boundaries. Verify useful output, purchase reductions and payroll changes independently.

Worked operating case
Hypothetical screening case: 250 days × 0.5 equivalent useful hour/day × 900 accepted kg/h × 60% realization, capped at 90,000 kg incremental demand, gives 67,500 additional sold kg/year. Net price $4.5/kg less incremental variable cost $2.9/kg gives $1.6/kg contribution. Verified baseline purchase savings are $7,200, realized payroll savings $0, energy $12,000, cleaning resources $8,000 and maintenance $5,000 per year. Deduct $20,000 additional annual fixed cost. Capacity requires actual additional conforming batches and downstream availability; it is not inferred from a shorter laboratory mixing test.
Calculated from these assumptions: steady annual net benefit $120,200; year-one net cash $71,130; cash payback 4.72 years; five-year NPV at 10% is −$106,957. Change the assumptions below to test a different case.

All defaults are illustrative. The default case is an operating-plant improvement, not a greenfield quote. For a new operation, set baseline savings to zero and enter every additional operating and capital cost.

| Base | $120,200 | −$106,957 | 4.72 years |
| Upside | $148,820 | −$7,571 | 3.88 years |
Downside: installed and site costs +20%, realization ×0.75 and unit contribution reduced by 20% of its absolute value. Upside: realization ×1.15, capped at 100%, and unit contribution improved by 10% of its absolute value. The demand ceiling still applies.
Formulas, scope and double-counting rules
Initial cash = (defined project scope + site additions) × (1 + contingency) + separate startup / shutdown cost + working capital. Contingency is conservatively treated as spent initially.
Sold incremental kg = min(days × recovered hours/day × constrained good kg/hour × realization, incremental demand). Contribution = sold incremental kg × (net price − incremental variable cost). New-volume labor, energy and packaging belong in that variable cost.
Baseline material benefit uses the verified percentage of actual purchases avoided at unchanged accepted baseline output. It is not a direct subtraction of two loss rates. Count a recovered kilogram once, either as its applicable cash saving or as incremental contribution.
Net annual benefit = contribution + independently realized baseline cash savings − added fixed operating cost. Year one scales gross benefits by the ramp factor while paying the full added fixed operating cost. Do not also count the same launch loss in the one-time startup amount.
Cash ROI = net annual benefit / initial cash. Five-year net ROI = (five-year cash inflows − initial cash) / initial cash. NPV = −initial cash + Σ cash flow(t)/(1 + discount rate)^t. Payback uses annual cash with linear interpolation within the recovery year. The threshold solver excludes terminal working-capital recovery.
This is a five-year screening horizon, not an asset’s entire life. No tax, debt, depreciation, grants, escalation, asset resale or additional replacement capital is modeled. Include recurring service costs in operating expense and use a detailed monthly budget for formal capital approval.

High-shear mixing and emulsification project FAQ
Does more shear always shorten the process?
No. Wetting, hydration, residence and emulsion formation are different mechanisms. Extra shear can damage texture, add heat or air, and leave the true constraint unchanged.
Is high-shear mixing the same as homogenization?
No. They may serve different dispersion and particle / droplet duties. Define the required final properties and specialist package sequence rather than treating the names as interchangeable.
Can a mixer price be compared without a trial?
A budget can be screened, but purchase comparison should use the same recipe envelope, accepted quality, complete cycle and supplier / installation scope.
Are these prices or returns a DPS commitment?
No. The example inputs exist to make the business-case calculation reviewable. Actual scope, prices, schedule, savings and performance need project-specific assessment and agreement.
What should the first DPS conversation include?
Bring the product and package mix, operating baseline, commercial target, retained assets, site constraints, available outage window and the capital options you are considering. Mark unknowns for measurement or supplier trials.
Bring an operating baseline and a testable investment brief.
Prepare the information below, export the assumptions you have modeled, and discuss the unknowns with DPS. An unmeasured input is a question to resolve, not a reason to invent precision.
