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.

    Retrieved from a retailer's document store, Euronics, which mirrors the manufacturer's booklet. Argos's manual library holds an earlier revision of the same guide, 200515_Mv1, which differs in a few printed amounts; the later revision is the one held here.

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.

  • Ninja Foodi MAX Health Grill & Air Fryer AG551UK: 60°C for 360 min

    A single published figure of six hours for 3mm slices, not a range. The chart prints no amount.

What usually goes wrong

Aroma driven off along with the water. Ginger's character sits in volatile compounds that leave above about 60°C, so raising the temperature to save time produces something fibrous and flat.

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.

Ginger in fast-moving hot air

Ginger root is fibrous, low in sugar and high in volatile aromatic compounds, which is the whole reason the dehydrating temperature is low. Above about 60°C those compounds evaporate along with the water and what is left is fibrous and flat-tasting. At 60°C over six hours the water leaves and most of the aroma stays, and the slices become brittle enough to grind. Thickness is the only variable that matters, and 3mm is thin enough that the water has a short path to the surface.
