Preparation
Peeled, cored and cut in slices of 3mm to 1.25cm, as the row prints. The slice is a band and is not held as one thickness.
How to tell it is done
- Leathery and no longer tacky to the touch
- No cool damp centre when a slice is torn
Where these figures came from — fresh
- Applies to
- Specific to this model
- Why this rating
- A published dehydrating row from the manufacturer's own Quick Start Guide for this machine, under a block headed fresh. The chart has no amount column, so the slice a row prints is the only measure it gives.

What this does not cover
- Published by the manufacturer for this model. It is evidence about this appliance and is not general advice.
- This machine has two drawers. The chart prints one amount for the row and does not say which drawer it is for, or whether it is for one drawer or both.
- The chart heads this block Fresh Fruits & Vegetables, and the row is held as fresh on that heading. The word is the block's and not the row's own.
- No quantity is stated. The dehydrate chart has no amount column, and this row prints no one slice thickness either.

Chilled
Cooked as fresh: use the fresh figures above. Raw food sold chilled is the fresh state under another name, and the charts those figures come from start from fridge-cold.
Manufacturer figures with no state given
This is a published figure for one named machine. The manufacturer does not say whether this is fresh or frozen. So it is kept apart from the figures above, and not used as the answer for any of them.

Published range of six to eight hours for slices of 3mm to 1.25cm. The chart prints no amount.
What usually goes wrong
Sticky slices that weld to the rack. Concentrated fruit sugar is glue once it is warm, and the thicker end of the published range makes it worse.
Running the appliance safely
The rules for the machine are the same whatever is in it: plug it straight into a wall socket, leave clear space round it, do not overfill it, do not leave it running unattended, and unplug it at black smoke or an electrical smell. They are set out once, each with its source and what to do if it has already happened, and not repeated on every food. Every rule for running an air fryer safely.
Pineapple in fast-moving hot air
Pineapple is high in both sugar and acid, and the acid keeps the flesh firm while the sugar caramelises, which is an unusually forgiving combination. On direct heat the cut faces darken and the fruit holds its shape, and the published instruction to turn it two or three times is about getting even colour rather than even cooking. Dehydrated, the same sugar concentration is what turns the slices leathery rather than brittle, and the fibrous core is the part that never softens either way.
Where to go from here
The pages that answer the questions this one tends to raise.
- How food actually gets crispyWhy patting it dry, spacing it out and a little oil are all the same instruction — so you can apply it when a page runs out.
- Why published timings differIf another chart says something else, this is usually why — and which one to believe.
