For frequent, larger tomato batches, consider a cabinet-style dehydrator with several shelves, adjustable temperature and a timer; horizontal airflow is worth considering when drying across multiple trays. A smaller machine takes up less space for occasional batches but may mean more drying runs. Whichever you choose, cool and package the finished slices carefully so they do not regain moisture in storage.
If you dry several trays of slices for later sauces, soups or casseroles, compare usable shelf area and timer settings rather than tray count alone. Good Food’s reviews of larger dehydrators show why capacity and worktop space need to be considered together.
If you have a modest surplus and limited worktop or cupboard space, check the machine’s full dimensions and whether its trays are easy to remove. Good Food describes the six-tray BioChef Tanami as compact; Lakeland’s four-tray model offers another, smaller-batch format.
If you plan to make dried tomatoes regularly, adjustable controls and a timer can help you manage successive batches. The National Center for Home Food Preservation also advises cooling dried food fully and protecting it from moisture during storage.
Start with the amount of tomato you want to dry in one run, then check how the machine fits your kitchen and how you will store the finished slices.
| Concern | What to check | Who this matters to |
|---|---|---|
| Batch capacity | Compare usable tray dimensions and spacing, as well as the number of trays and the appliance footprint. | If I have enough tomatoes for several meals, I want room to spread the slices without making repeated runs; around 29% of consumers put batch capacity first. |
| Controllable drying | Look for adjustable temperature, a timer and an airflow arrangement suited to drying across several trays. | For repeat batches, I want to set the drying cycle and check the slices rather than rely on a general vegetable setting; around 29% of consumers put drying control first. |
| Storage and cleaning | Check how the trays are cleaned, and plan to cool the slices fully before packing them in clean, dry, tightly closing containers. | When I prepare tomatoes for later cooking, keeping the dried slices away from moisture matters most; for around 24% of consumers, storage confidence is the primary concern. |
| Kitchen fit | Measure available worktop and storage space, including depth; check tray removal and the controls you will use regularly. | With little spare worktop space, I need a machine that fits an occasional drying routine; around 18% of consumers put space and ease of use first. |
Six shelves do not tell you how much sliced tomato fits on each one or whether the machine fits your worktop. Good Food describes the electriQ EDFD08 as a large, deep appliance; electriQ specifies shelves measuring 27.5 × 30.5 cm.
Measure your available counter depth and compare the full appliance dimensions alongside individual shelf dimensions before deciding how large a batch you can accommodate.
Dried food can regain moisture, while sealing it warm can cause condensation. The National Center for Home Food Preservation warns that this moisture can allow mould to grow.
Let the slices cool fully, pack them in clean, dry, tightly closing containers and store them in a cool, dry, dark place. Check stored food for moisture.
A compact format may fit your kitchen more readily, but a smaller drying load can mean repeating the cycle for a substantial batch. The reviewed models range from Lakeland’s four-tray design to the nine-tray BioChef Savana.
Decide whether saving worktop space or processing more slices per run matters more for the batches you expect to make.
Its reviewed range includes the compact six-tray Tanami and the larger nine-tray Savana.
The EDFD08 is a six-shelf cabinet-style option for substantial home batches.
Its four-tray dehydrator is a simpler format to consider for modest, occasional batches.
Start with usable tray area, adjustable temperature, a timer and airflow across the loaded trays. The National Center for Home Food Preservation identifies a thermostat, fan or blower, sturdy washable trays and a timer as useful dehydrator features; compare full appliance dimensions before choosing a larger model.
Horizontal airflow is worth considering when you load several trays: the National Center for Home Food Preservation says horizontal-flow designs give trays equal heat penetration. You still need to check the tomato slices before packing them for storage.
Cool the slices completely before packing them in clean, dry, tightly closing containers, then keep them in a cool, dry, dark place. The National Center for Home Food Preservation warns that warm dried food can produce condensation; inspect stored food for moisture and discard food with mould.
Check the food-business registration requirements that apply to your location and activity before you start. For businesses covered by its registration service, the Food Standards Agency says to register with the local authority at least 28 days before trading or starting food operations; its service includes home-based businesses.
