Featured tool
Water Removed & Dry Yield Calculator
Enter a fresh weight and a freeze-dried weight to see how much weight was removed, the weight reduction, the dry yield percentage and the fresh-to-dry ratio. This is the number behind every "how much did it lose?" question.
Rehydration
The water side of freeze drying: how much to add back.
Water Loss & Dry Yield
What the process removes from your starting weight.
Raw-to-Dry Planning
Planning purchases and targets with an expected dry yield.
Tray Loading
Spreading a batch across the trays you have.
Net Package Weight & Packaging
Net food weight, package counts and packaging weight.
Net Package Weight Calculator
Subtract bag, oxygen absorber, label and other packaging to find the net food weight in a sealed package.
Open toolPackage Quantity Calculator
Full packages and remaining product from total dry weight and target net weight per package.
Open toolPackaging Weight Calculator
Total bag, absorber and label weight for a number of packages, useful for shipping and gross weight.
Open toolCosts & Pricing
Batch costs, cost per unit and margin or markup pricing.
Batch Cost Calculator
Total batch cost from product, electricity, packaging, labor and other costs, with per-unit and per-package outputs.
Open toolCost per Finished Product Calculator
Spread a batch cost over the finished dry weight: per gram, per 100 g, per kilogram, per ounce and per pound.
Open toolCost per Package Calculator
True cost per finished package from batch totals or cost per gram, plus packaging and labor add-ons.
Open toolMargin & Selling Price Calculator
Set a selling price from your cost using a gross margin or a markup, with the two formulas kept separate.
Open toolBatch & Production Planning
Capacity, comparisons and monthly production schedules.
Batch Comparison Tool
Compare two batches side by side on weights, yield, cycle time, trays and your own observations.
Open toolBatch Capacity Planner
Theoretical and practical batches, fresh input capacity and dry output estimate for a planning period.
Open toolProduction Planning Calculator
Batches needed, machine hours and estimated operating days to hit a monthly fresh-product goal.
Open toolUnit Converters
Weight, water volume and temperature.
Batch Log
A client-side record for every batch, ready to be copied or printed.
