Insulated Food Carriers

It depends on how full it is, what it was packed at, how many times it is opened and the ambient temperature. A full box opened once holds far longer than a half-empty one opened at every stop.

Any holding figure is specific to the product and belongs on the product page specifications. Test it with your own food and a probe before you rely on it for a function.

No. A passive carrier only slows the loss of whatever temperature you put in it, which is why product has to leave the kitchen at the temperature you want it to arrive at.

For commercial insulated food carrier work with long runs, add rated hot or cold packs. If you need actual heating in transit, a powered holding cabinet is the right tool.

Size it on gastronorm pans rather than litres, because that is how the food will arrive. Count the pans your biggest job needs and buy the box that takes them, plus one spare slot.

Several smaller boxes beat one large one for most caterers: they are liftable by one person and you can keep hot and cold separate.

Never in the same box. Hot product will warm the cold, the cold will cool the hot, and you will end up with both sitting in the range you were trying to avoid.

Run dedicated hot and cold boxes and mark them clearly. Keep a probe thermometer with each so you can record the temperature at both ends.

Wiped out after every job and washed properly on a schedule, with attention to the gasket and the catch recesses where spills collect. Insulation soaks up smells if a spill is left in a seam.

Most are not dishwasher items because of their size and the insulation. Use the sanitisers in the disinfectant and sanitisers range and dry with the lid open.

Top-loading boxes hold temperature better because cold air does not fall out when you open them, and they stack. Front-loading cabinets are far easier to load and unload at a venue with limited bench space.

Caterers who work out of a van usually run both. Front-loaders pair with a catering trolley, which is where most of the back strain goes away.

Secured, flat and not stacked above head height. A full carrier is heavy and a box that shifts on a corner will open, which is the common cause of a ruined job.

Strap them against a bulkhead or into a rack. A platform trolley for loading saves the lifting at both ends.
