Starting Moisture by Product, and the Water Load It Implies

Sizing starts from starting moisture, and most people do not know theirs. This table exists so you can begin with a defensible figure and then measure — because measuring beats a table, always.

How To Use This

A starting point, not a substitute for measuring

Two batches of the same product from different growers in different seasons will differ. Use the table to plan, and measure before you commit.

Read across: the category gives a typical starting moisture range, and the water load column shows what a 1,000 lb batch of that material would give up when dried to 2% finished moisture. Scale linearly for other batch sizes.

The arithmetic is the same everywhere on this site: solids = batch × (1 − start); finished = solids ÷ (1 − final); water = batch − finished.

The Table

What The Table Cannot Tell You

Three things that move the answer more than the category does

Which is why this is a starting point and a moisture meter is the finish.

Variety and season. Two strawberry crops differ by several points of moisture, which is tens of pounds of water on a 1,000 lb batch.

Preparation. Slicing, dicing, blanching, pureeing and pretreatment all change both moisture and how the water gets out.

Target finished moisture. Dropping from 2% to 1% removes only a little more water but can add disproportionate time in secondary drying — the last water is the slowest.

Questions buyers ask before they call

What is the typical starting moisture of fruit for freeze drying?

High-moisture fruit such as berries and melon typically runs 85–92%; tree and stone fruit around 80–86%. A 1,000 lb batch at 88% dried to 2% removes roughly 878 lb of water. Ranges are indicative — measure your own material.

How do I calculate water load from starting moisture?

Dry solids = batch weight × (1 − starting moisture). Finished weight = solids ÷ (1 − final moisture). Water removed = batch weight − finished weight.
