**Short answer:** NCHFP guidance is to dry most fruits and vegetables at about 140 F, and herbs at a lower 95 to 115 F so their oils are not lost. For jerky, USDA FSIS says to heat meat to 160 F (poultry to 165 F) before drying, and keep the dehydrator at 130 to 140 F during drying. Times run from a few hours for herbs to many hours for fruit.

Dehydrator dials usually run from about 95 F to 160 F or higher, and the right setting depends on the food. Too low and food dries slowly and can spoil; too high and the outside hardens while the inside stays moist. This chart gives the temperatures that NCHFP and USDA guidance use for home drying, typical time ranges, and the doneness test for each food group. Your machine, slice thickness and humidity all change times, so test for doneness rather than going by the clock.

## Food dehydrator temperature chart

| Food | Dehydrator temperature | Typical time | Done when |
| --- | --- | --- | --- |
| Herbs | 95 to 115 F (up to 125 F in humid areas) | About 1 to 4 hours | Leaves crumble easily |
| Fruit slices | 140 F | Several hours to a day or more | Leathery and pliable, no moist spots |
| Fruit leather | 140 F | Several hours | Not sticky; peels off cleanly |
| Vegetables | 140 F | Several hours | Brittle or crisp |
| Beef or game jerky | 130 to 140 F during drying, after heating meat to 160 F | Several hours | Bends and cracks but does not snap |
| Poultry jerky | 130 to 140 F during drying, after heating meat to 165 F | Several hours | Bends and cracks but does not snap |

Drying temperatures by food (NCHFP and USDA FSIS guidance)

Note: Jerky safety comes from heating the meat to 160 F (165 F for poultry) to kill bacteria, not from drying temperature alone. USDA FSIS recommends steaming or roasting strips to that temperature before drying. NCHFP also describes a tested method of heating dried strips in the oven after drying.

## Herbs: low and gentle

Herbs carry flavorful oils that fade at high heat. NCHFP suggests preheating the dehydrator to between 95 F and 115 F, and going up to about 125 F in humid areas. Rinse herbs, shake off water, and spread them in a single layer. Most herbs dry in about 1 to 4 hours.

Herbs are dry when leaves crumble and stems break when bent. Store them whole and crumble when you use them for better flavor. For more, see [how to dehydrate herbs](https://freezeandseal.com/blog/how-to-dehydrate-herbs).

## Fruits and vegetables at 140 F

Most fruits and vegetables dry well at 140 F. Higher temperatures can harden the outside before the inside dries, a problem called case hardening, which traps moisture inside. Cut pieces evenly, about 1/4 to 1/2 inch thick depending on the food, so they finish together.

NCHFP recommends pretreating light colored fruit such as apples, pears, peaches and bananas with an ascorbic acid or similar dip to limit browning. Most vegetables should be blanched before drying to stop enzyme action and help them keep color and flavor. Follow the NCHFP directions for each vegetable.

- Fruit is done when it is leathery and pliable, with no pockets of moisture when you cut or squeeze a piece.
- Vegetables are done when they are brittle or crisp.
- Let a test piece cool before judging. Warm food feels softer than it really is.

## Jerky temperature and safety

USDA FSIS guidance for jerky has two parts. First, heat the meat to an internal temperature of 160 F for beef and game, or 165 F for poultry, to destroy bacteria. Second, dry it in a dehydrator that holds 130 to 140 F throughout drying. A dehydrator alone, at a typical setting, may not get meat hot enough fast enough to kill bacteria such as E. coli and Salmonella.

Use lean meat, trim visible fat, and slice thinly and evenly. Marinate in the refrigerator.

Note: Wild game, especially bear and wild pig, can carry Trichinella. Follow USDA and extension guidance for game, which may require freezing or cooking steps before making jerky.

## What changes drying time

If some trays finish well before others, see [dehydrator drying unevenly](https://freezeandseal.com/blog/dehydrator-drying-unevenly).

- **Slice thickness.** Thicker pieces take much longer.
- **Water and sugar content.** Juicy and sugary fruits dry slowly and stay sticky longer.
- **Humidity.** Humid air slows drying a lot.
- **Load.** Full trays and blocked airflow add hours.
- **Airflow design.** Rear fan box units dry trays more evenly than many bottom fan stackers. See [horizontal vs vertical airflow](https://freezeandseal.com/blog/horizontal-vs-vertical-airflow-dehydrator).
- **Actual temperature.** Dials are not always accurate. An oven thermometer on a middle tray tells you what the food really sees.

## After drying: conditioning and storage

Moisture is rarely even across a batch of dried fruit. NCHFP recommends conditioning: pack cooled fruit loosely in a glass jar about two thirds full, close it and shake it daily for 7 to 10 days. If moisture beads form inside, put the fruit back in the dehydrator. Vegetables are dried until brittle and need less conditioning.

Store dried food in airtight containers in a cool, dark, dry place. NCHFP notes most dried fruits keep about a year at 60 F and about 6 months at 80 F, and dried vegetables about half as long. Home dried jerky keeps 1 to 2 months at room temperature per USDA FSIS. Vacuum sealing helps; see [best vacuum sealers](https://freezeandseal.com/best/best-vacuum-sealer) and our [storage life by method](https://freezeandseal.com/tools/storage-life-table) tool.

## Frequently asked questions

**What temperature should I dehydrate fruit at?** About 140 F, per NCHFP guidance. Higher heat can harden the outside and trap moisture inside.

**What temperature for jerky in a dehydrator?** Keep the dehydrator at 130 to 140 F during drying, and heat the meat to 160 F (165 F for poultry) before drying, as USDA FSIS directs.

**How long does a food dehydrator take?** Herbs take about 1 to 4 hours. Most fruits and vegetables take several hours, and juicy fruits can take a day or more. Test for doneness.

**Can I dry everything at the highest setting to save time?** No. High heat can case harden fruit and vegetables and scorch herbs. Use the temperature for each food.
