How long to dehydrate apple chips in a dehydrator?

Dehydrating apple chips in a dehydrator is a great way to make a healthy, crispy snack that can last for weeks or months. But knowing how long to dehydrate the apple slices is key to getting the right texture.

What is the ideal texture for dehydrated apple chips?

The ideal texture for dehydrated apple chips is very crisp and dry, with no moisture or flexibility left. The chips should snap cleanly when bent and not feel leathery or pliable at all. This ensures they will remain crisp and crunchy when stored long-term.

What factors affect dehydrating time for apple chips?

There are a few key factors that affect how long it takes to fully dehydrate apple chips:

  • Thickness of the slices – Thinner slices dehydrate faster
  • Water content of the apples – Juicier varieties take longer
  • Efficiency of the dehydrator – Higher wattage equals faster drying
  • Humidity in the air – Wet weather lengthens dehydration

Taking these variables into account allows you to estimate the time needed for drying apple chips in your specific conditions.

How thin should apple slices be for dehydrating?

For dehydrating into apple chips, apple slices should be cut between 1/8 to 1/4 inches thick. Slices that are too thick take much longer to fully dehydrate. Aim for a thickness where you can just faintly see light shining through the slices.

Use a mandoline slicer or sharp knife to cut the apple slices evenly. Consistent thickness allows the slices to dry at the same rate.

Which apple varieties dehydrate faster or slower?

The natural water content of different apple varieties affects dehydration time. Here are some drying times for common types:

  • Fast Drying Varieties (6-10 hours)
    • Fuji
    • Golden Delicious
    • Gala
    • Jonagold
    • Pink Lady
  • Moderate Drying Varieties (10-14 hours)
    • Honeycrisp
    • Braeburn
    • Jazz
    • McIntosh
  • Slow Drying Varieties (14-18+ hours)
    • Granny Smith
    • Rome
    • Arkansas Black
    • Mutsu

As you can see, juicy apples like Honeycrisp take longer to fully dehydrate than lower moisture types like Fuji. Keep this in mind when choosing apple varieties and estimating drying time.

How does the wattage of a dehydrator affect drying time?

Higher wattage dehydrators heat up faster and run at hotter temperatures. This causes faster drying of apple chips. Here is how wattage compares:

Dehydrator Wattage Average Drying Time for Apples
500 watts 14-22 hours
750 watts 10-18 hours
1000+ watts 6-14 hours

As you can see, a 500 watt dehydrator may need up to 22 hours while a 1000+ watt model may only need 6-14 hours. The higher wattage equals faster drying.

How does ambient humidity affect dehydrating time?

Humidity in the surrounding air has a major impact on dehydration time. The natural moisture in the air competes with the dehydrator to rehydrate the apple slices. Here’s a comparison:

Ambient Humidity Average Drying Time Increase
60% or lower No increase
60-80% 2-4 hours longer
80% or higher 6+ hours longer

As you can see, high humidity environments can increase dehydration time by 6 or more hours compared to low humidity. Run the dehydrator on dry days for faster results.

What temperature should a dehydrator be set at?

The ideal dehydrator temperature for drying apple chips is 130-140°F. This allows moisture to evacuate quickly while preventing the apples from cooking. Lower temperatures below 130°F slow the drying process. Higher temperatures above 140°F can cause the apples to become discolored or tough.

Maintain the dehydrator temperature between 130-140°F for the entire drying period for best results. Some dehydrators allow you to adjust the thermostat to precisely hold this range.

How to tell when apple chips are fully dehydrated?

Here are some ways to test apple chips for complete dehydration:

  • Texture – Chips should be completely crisp and brittle with no pliability or moisture. They should snap when bent.
  • Color – Fully dried chips are typically darker and more translucent than fresh slices.
  • Moisture test – There should be no condensation inside a sealed container after cooling the chips for an hour.
  • No moisture pockets – Apple slices should be dried uniformly with no juicy spots when bitten.

Testing a few slices from different trays will ensure the entire batch is fully crisped and dehydrated. If any moisture remains, continue drying and testing until the above criteria are met.

What is the average dehydrating time for apple chips?

Taking into account all the factors discussed, the average dehydrating time for apple chips is 10-14 hours for most situations. However, drying time can range from 6 hours up to 22 hours depending on:

  • Apple variety moisture content
  • Slice thickness
  • Dehydrator wattage
  • Ambient humidity

Be sure to take these key factors into account when estimating the time needed to dehydrate your apple chips.

Tips for faster apple chip dehydration

Here are some tips to help speed up the apple chip drying process:

  • Use drier apple varieties like Fuji or Gala
  • Cut slices 1/8 inches thick or thinner
  • Use the highest wattage dehydrator available
  • Dehydrate on dry, low humidity days
  • Rotate the trays and stir chips occasionally
  • Blot slices with a paper towel before dehydrating

Step-by-Step Instructions for Dehydrating Apple Chips

Follow these steps for crispy, flavorful dehydrated apple chips:

  1. Select apples – Choose dryer varieties like Fuji or Gala for faster drying.
  2. Wash and dry apples – Wash then pat dry with paper towels to remove excess moisture.
  3. Slice apples – Use a mandoline for 1/8-1/4 inch thick uniform slices.
  4. Pre-treat slices (optional) – Soak in lemon water or spray with lemon juice to prevent browning.
  5. Blot slices – Remove moisture with paper towels before dehydrating.
  6. Arrange on trays – Place slices in a single layer, not overlapping.
  7. Dehydrate at 130-140°F – Dry until completely crisp and brittle, about 10-14 hours.
  8. Rotate trays and stir chips – Occasionally shuffle trays and mix chips for even drying.
  9. Test for doneness – Chips should be crisp with no moisture pockets.
  10. Store in airtight containers – Cool completely then store in sealed bags or jars.

Storing Dehydrated Apple Chips

For maximum crispness and shelf life, store dried apple chips in air-tight containers at room temperature. Keep out of direct sunlight and away from moisture and humidity.

Properly dehydrated chips can keep for up to 1 year in ideal storage conditions. For longer term storage of 2 years or more, consider refrigerating or freezing the sealed apple chip containers.

Check periodically for moisture and any signs of softening. Discard any chips that appear moist or are no longer crisp.

Frequently Asked Questions

Can you dehydrate apples without a dehydrator?

Yes, you can dehydrate apples in the oven without a dehydrator. Simply slice apples thin, arrange on parchment lined baking sheets, and bake at 150°F for 6-12 hours with the oven door propped open. Check frequently for doneness.

Do you need to pretreat apple slices before dehydrating?

Pre-treating is optional but helps stop apple slices from browning. Soak briefly in lemon juice and water, or spray with fruit protector spray or ascorbic acid powder before dehydrating.

How long do dehydrated apple chips last?

Properly dried apple chips can last 6-12 months at room temperature when stored in airtight containers. Refrigeration or freezing can extend shelf life up to 2 years.

Can dehydrated apples be rehydrated?

Yes, dried apple chips can be rehydrated by soaking in hot water for 30-60 minutes until pliable. Rehydrated apples work great for baking, making applesauce, adding to oatmeal, etc.

Is a dehydrator required or can you use an oven?

A dehydrator is ideal for making apple chips, but you can use a regular oven if needed. Prop the door open slightly and keep temperature around 150°F.

Conclusion

Dehydrating apple chips is easy and rewarding when you follow the proper techniques. For the ideal crisp texture, allow 10-14 hours for most scenarios. But adjust time as needed based on apple variety, slice thickness, dehydrator wattage, and ambient humidity. With the right process, you can enjoy shelf-stable crunchy apple chips all year long.
