Biohacker Ingredient Intelligence

Freeze-dried yield and cost calculator

Estimate finished mass, feed-to-output ratio and production cost from your own solids, moisture and cost assumptions.

Free tool. No sign-up. Calculations stay on your device.

Your scenario. Verify every assumption with measurements or documentation.

Your inputs

Ingredient (optional context)

Selecting a fruit does not fill in solids, costs or process suitability.

Mass balance

Ready-for-drying feed mass

Use prepared material, after peeling, filtering or other preparation losses. Costs are always entered per kg, even when mass is in lb.

Mass unit

1 lb = 0.45359237 kg

Total dry solids (% wet basis)

Not °Brix. Use measured or documented total solids, including insoluble solids.

Dry-solids retention (%)

The fraction of initial dry solids retained in the finished product, not the percentage of water removed. 95% is only an example.

Final moisture (% wet basis)

Must be below initial moisture. Moisture content is not water activity and does not establish food safety.

Source of physical inputs

Production cost assumptions

Single currency

No exchange rates or currency conversion. Changing currency clears all prices and costs.

A blank or unknown cost is not zero. Unit cost is unavailable until every cost is entered or explicitly excluded.

Raw material / kg feed: Cost treatment

Processing fee / kg: Cost treatment

Packaging / kg finished: Cost treatment

Fixed overhead / batch: Cost treatment

Processing fee basis

Selling price / kg finished (optional)

Use a decimal point without thousands separators, e.g. 1.5. Maximum input: 1 trillion; no exponent notation.

Estimated results

Enter valid mass, solids, retention and moisture to see the mass balance.

Physical inputs include assumptions, not verified measurements.

Engineering estimate only. Not a quotation, guaranteed yield, process validation, COA or safety assessment. Factory-cost scenario, not landed cost.

Excludes costs not entered: freight, insurance, duties, taxes, QA, certifications, energy, financing, spoilage and selling expenses. Requires a separate commercial and technical review.

Discuss the next step

Attach my technical inputs to the RFQ for Biohacker's review. Also attach my cost and selling-price assumptions. Use estimated finished mass as an editable purchase target. I intend to purchase this quantity of finished product.

Optional and unchecked by default. Context uses this tab's storage for up to 30 minutes, then is removed on transfer. No calculations in URLs, advertising pixels, backup forms, Supabase or WhatsApp. Only your final RFQ submission sends the selected attachment through the existing email provider.

A development inquiry is not a purchase commitment. Processing availability and feasibility are reviewed separately; Brazil-specific services are not assumed available internationally.

Methodology and units

Mass balance

All percentages are wet-basis mass fractions, divided by 100 once. The model tracks retained dry solids, then adds the specified residual water.

M₀: prepared feed (kg); s: total solids fraction; r: dry-solids retention; u: final moisture fraction; Mƒ: finished mass (kg).

S₀ = M₀ × s

Sᵣ = S₀ × r

Mƒ = Sᵣ ÷ (1 − u)

Finished yield: 100 × Mƒ ÷ M₀

Feed-to-finished ratio: M₀ ÷ Mƒ

Residual water in finished product: Mƒ × u

When solids are lost, the difference between initial and final mass is not all sublimated water. This tool does not estimate vapor load, energy or drying time.

Production cost assumptions

Batch cost = feed × raw cost + charged mass × processing fee + finished mass × packaging + fixed overhead. Unit cost = batch cost ÷ finished mass.

No exchange rates or currency conversion. Changing currency clears all prices and costs.

Excludes costs not entered: freight, insurance, duties, taxes, QA, certifications, energy, financing, spoilage and selling expenses. Requires a separate commercial and technical review.

High-sugar or high-oil materials and carrier-containing formulations need product-specific process evaluation. This mass balance cannot establish freeze-drying suitability or shelf life.

Method references

References explain drying and its limitations; they do not certify the input data, costs or this scenario.

Questions about the calculator

Can I use °Brix as total solids?

No. °Brix is not a general measurement of total dry solids. Obtain a suitable total-solids measurement or documented specification for the prepared feed.

Is 95% retention a standard yield?

No. It is only an illustrative assumption for retained dry solids. Preparation losses and process-specific solids losses need separate evidence.

Why is there no unit cost?

Unknown costs are not treated as zero. Enter each cost, including zero when justified, or explicitly mark it as not applicable. A valid mass balance can still be calculated without prices.

Are these Biohacker supplier prices?

No. All prices are entered by you or loaded as a clearly labeled example. Availability, MOQ, specifications, lead time and pricing require a separate RFQ review.

Does a low final moisture prove safety?

No. Moisture is not water activity. A mathematical mass balance does not validate microbiology, shelf life, packaging, process suitability or regulatory compliance.

Will my calculations be sent to Biohacker?

Not automatically. Calculations run locally. You can separately authorize technical context and economic assumptions before opening the existing RFQ, review the attachment there and submit it yourself.

Product specifications and supply conditions are assessed per project, not inferred from this calculator.
