Ginger Drying Recovery & Dry Ginger (Sonth) Yield
Dries ginger
Enter your fresh ginger weight and recovery percentage to get the dry ginger (sonth) you'll end up with, the fresh-to-dry ratio, the water lost in drying and the value of the dried crop.
Enter your ginger harvest
Next: expect ~220 kg dry ginger (ratio ~4.6:1); dry to ~10% moisture out of direct harsh sun to keep colour and aroma.
Recovery and quality depend on variety, fibre, peeling and drying method; bleached/limed sonth and oil/oleoresin extraction add value.

Turn perishable rhizomes into storable spice
Fresh ginger is heavy, wet and spoils fast — but dried into sonth it becomes a dense, fragrant spice that stores for months and travels well. Washing, often peeling, slicing and then drying the rhizomes down to about 10% moisture concentrates the pungency and aroma while stripping out the perishability. By the end you keep only about a fifth to a quarter of the fresh weight, yet every kilo is worth far more — provided you dry out of harsh sun to protect the colour and oils.
This tool gives the dry ginger yield, the fresh-to-dry ratio, the water lost and the value of the dried crop from your fresh weight and recovery. Use it to plan drying space and labour, compare lots, and price your output. Pair it with the Turmeric Curing Recovery, Dehydration Ratio and Value Addition Profit tools for a full processing plan.

Frequently Asked Questions
What is dry ginger (sonth)?+
Sonth is fresh ginger that has been washed, often peeled, sliced and dried until hard and shelf-stable. Drying concentrates the pungency and aroma, removes the perishability of the fresh rhizome, and gives a high-value, easily stored and transported spice used in cooking, tea and traditional remedies.
How is dry ginger yield calculated?+
Dry ginger = fresh weight × recovery%. Fresh ginger dries down to roughly 19–25% of its fresh weight, so 1000 kg of fresh rhizomes typically gives about 190–250 kg of sonth. Enter your own recovery if you know it from past lots; the balance is water driven off during drying.
Why is the recovery only about a fifth?+
Fresh ginger is mostly water. Drying removes that water until the moisture is low enough for safe storage, which leaves only the dense, dry solids — about a fifth to a quarter of the starting weight. Peeling, older rhizomes and higher fibre all shift the exact recovery up or down a little.
Should I peel ginger before drying?+
Peeling gives a cleaner, lighter-coloured sonth that often grades and sells better, but it lowers recovery slightly and adds labour. Some markets prefer unpeeled or lightly scraped ginger. Slicing the rhizomes before drying — peeled or not — speeds drying and gives a more even product.
What moisture should dry ginger reach?+
Dry it down to about 10% moisture — at that point it is hard, snaps cleanly and resists mould in storage. Slices should be brittle, not leathery. Drying too little leaves it prone to spoilage; drying in harsh direct sun can fade the colour and lose volatile aroma compounds.
Why dry out of harsh direct sun?+
Ginger's value is in its pungent oils and aroma, and very harsh sun can bleach colour and drive off those volatiles, giving a paler, less aromatic sonth. Drying in shade, under a roof, or in a controlled drier preserves colour and aroma while still removing the moisture for storage.
Can I estimate value from this?+
Yes — enter your dry ginger price per kg and the tool multiplies it by the dry yield to estimate the dried crop's value. Because drying concentrates the spice and removes perishability, sonth fetches far more per kg than fresh ginger, which is why the recovery percentage matters to your return.
How does ginger drying compare to turmeric?+
Both turn a wet, perishable rhizome into a dense, storable spice at roughly a fifth of the fresh weight, but turmeric is boiled first to fix and even its colour, whereas ginger is usually just washed, sometimes peeled, sliced and dried. See the Turmeric Curing Recovery tool for that crop.
Are these figures exact?+
They are reliable planning figures. Real recovery shifts with variety, rhizome maturity and fibre, whether you peel, fresh moisture and how thoroughly you dry. Weigh a few lots through your own process to learn your true recovery, then use that percentage here for sharper estimates.
