Galley equipment
To eliminate safety risks, all equipment has to be approved by the CAA or FAA before it can be installed in aircraft. Anything which could be a potential hazard to the aircraft must be eliminated. Also, in the operation of equipment there are special safety features which arise as the result of the nature of air transportation, with its steep angles of take-off and landing. For example, coffee makers and water boilers have an incorporated brew handle to secure the liquid container and a written warning on the machine. Some airlines will incorporate fixed equipment into their galleys; typically ovens for the regeneration of entrees and water boilers or coffee machines. A recent trend, however, is to use flexible modular systems which will allow equipment to be interchanged for specific flights.
Cold storage
The need to hold protein foods at low temperatures is even greater within an aircraft environment than in any other catering establishment. The duration of long-haul flights is sufficient for passengers to suffer the effects of an excess intake of harmful micro-organisms through their food consumption. Hence such foods have to be held at safe temperatures. Most caterers will supply foods at or below 5°C, and then a variety of methods will be used to hold the food at or below this temperature. This can be achieved in a number of ways
A simple cooling agent An example is solid carbor dioxide (dry ice'), which can be located within the trolley or cart. Foil capsuies of this item can be located in small trays at the top of each trolley which is packed with its 'tray ets'. As cold air falls, the chilled air will then circulate throughout the insulated trolley.
A dry ice 'snow' machine This alternative can be used to pack dry ice around the tray sets within the trolleys. This can either be achieved by snow gun or by locating an open trolley against a machine with injectors at several heights which will dispense dry ice to a variety of locations within the trolley simultaneously.
A chiller unit This can be incorporated into the galley design which will then circulate chilled air around the trolleys when they are located in their bay
