About DryHarvest

Drying food is one of the oldest ways people have kept food edible long after harvest or slaughter — and one of the easiest to get a little wrong. A slice cut too thick, a dehydrator running too cool, a cure ratio guessed instead of weighed — small choices that change whether a batch turns out well. DryHarvest exists to take the guesswork out of that arithmetic so the drying itself can go right.

Rather than long essays you have to wade through, the site is a set of small, single-purpose calculators, each aimed at one real step in the process. The Drying Time Calculator scales a baseline hour range to your food, slice thickness, and temperature. The Dehydrator Temperature Guide looks up the commonly recommended range for your food in °F and °C. The Jerky Cure & Salt Ratio Calculator converts a meat weight into salt and optional cure #1 amounts. The Water Activity Estimator estimates how salt and sugar content affect a brine’s water activity. The Rehydration Ratio Calculator converts between a dried weight and its rehydrated yield, and the Batch Yield Estimator projects how much finished product a fresh batch will produce.

Beyond the calculators, the blog and learnsection cover the reasoning the tools rest on — how slice thickness and temperature change drying time, why salt and sugar lower water activity, what a common cure ratio looks like, and how drying methods differ from smoking or curing — and the Museum of Drying & Preservation is a browsable collection of dried meats, dried fruits, dried herbs and spices, and drying methods and equipment from around the world, with every entry, image, and fact drawn from Wikipedia and Wikimedia Commons.

A few things worth stating plainly. DryHarvest is independent and not affiliated with any equipment maker, food-safety agency, or publisher. It is supported by advertising, which is how the tools stay free with no account required. The calculators provide general guidance for home food preservation, not medical or regulatory advice — they show their working and round for readability, but for anything beyond home, short-term use you should confirm results against your equipment’s manual and a current food-safety source.
