- Put food in the boxes hot!
|
The hotter the food is when it goes in the transport boxes the longer it will stay at a suitable temperature for consumption |
|
|
If you use a small food transport box completely full of hot food product you have the the maximum quantity of product relative to the surface area of the box. This will minimize any heat loss from the food transport box
|
- Larger food transport boxes have higher heat loss
|
A Large insulated food transport box will have a larger surface area and hence higher heat losses |
- Larger insulated transport boxes contain more air which will absorb heat from the food
|
A large insulated food transport box will, if not filled, contain a large quantity of air which will absorb heat from the hot food being transported
In addition air gaps between hot products will allow circulation inside the insulated box increasing cooling rates
|
|
|
Adding a heat source such as a Thermo-Boost to the box will greatly increase the time hot food can be kept in an insulated food transport box |
|
|
A Thermo-shield acts in two ways by reflecting heat back into the food and also reducing air circulation inside the insulated transport box |
- When packing food boxes try to form layers to avoid air flow or use Thermo-shield
|
If food is packed in layers which stop air convection inside the transport box, heat transfer from the hot food to the inside surface of the insulated box will be reduced |
- When a Thermobox is opened and closed for multiple deliveries heat inside the transport box is lost
|
When carrying out multiple deliveries such as meals on wheels hot food delivery repeated opening of the insulated box causes rapid heat loss. This heat loss is greatly reduced by use of products such as the Thermo-Shield which acts as a divider between layers/meals inside the hot meals box. This division drastically reduces the quantity of hot air leaving the box and the associated heat loss. |
