Glossary of Terms
Arranging
Positioning the food correctly on the plate to obtain even heating.
Cavity
The interior of the oven where the food is placed for heating.
Ceramic Insulating Tray
Accessory supplied with oven specifically to place between a metal container and Wire Rack Shelf when cooking by COMBINATION.
Combination
Combining Microwave energy with either Grill, Fan Grill or Convection, or with both Grill and Convection
Commercially prepared foods
Foods prepared and cooked at the manufacturers and supplied, usually in a frozen from, to caterers.
Conduction
Transfer of heat through the food, giving even temperature distribution.
Cooking/Prime cooking
The process of heating raw foods.
Defrosting
The processing of taking cooked or raw food from a frozen to thawed state.
Density
The compactness of foods: of open or close texture.
Foods prepared “in house” from raw ingredients.
Magnetron
The component responsible for changing electrical energy to microwave energy.
Reheating
The process of heating previously cooked foods to a specific temperature.
Salmonella/Lysteria
Food poisoning bacteria.
Sequential/Multi-stage heating
A series (maximum 3) of separate heating settings with times entered before START pad is pressed. The oven then automatically operates the different settings in sequence.
Shielding
Covering areas of food already defrosted or cooked, with aluminium foil.
Standing Time
Watts/Kilowatts
The measured unit of power; there are 1000 watts
(W)in one kilowatt (kW).
Waveguide
A rotating metal plate which disperses the microwave energy into the cavity.
Wire Rack Shelf
Accessory supplied with oven to use as shelf when heating by COMBINATION, CONVECTION, FAN GRILL, GRILL CONVECTION or GRILL.
Dish Test
To check if a container is suitable for use on MICROWAVE, follow instructions below:
1.Check on the base of a container to see if it is microwave safe. If you are uncertain, check a piece of china using the simple dish test.
2.Place a microwave safe container with 1/2pint (300ml) of cold water on base of microwave. Alongside, place container to be tested. Heat on HIGH power for 1 minute.
Result: A suitable container for microwave will remain fairly cool but the water will feel warm.
If the container is warm or hot then it is absorbing some microwave energy and SHOULD NOT be used. China which absorbs energy will not harm the oven but will slow down the heating of the food.
If Arcing Occurs
Arcing is the static discharge during microwave heating which occurs between any two metals eg the side of the cavity and a metal container: characterised by a blue flash.
If arcing occurs, stop oven immediately. Check that, if a metal container is being used, it is not touching sides or door of oven. Transfer food to a suitable container if necessary.
Arcing may also occur if foil is incorrectly used to shield during DEFROSTING and COOKING. Use SMOOTH pieces of foil and make sure they do not touch roof or walls of oven.
Arcing may also occur if food splashes are not cleaned off and become carbonised. KEEP OVEN AND ACCESSORIES CLEAN.
