Infrared Ovens and Microwave Ovens
Infrared Ovens The use of infrared energy, which is a from of radiant heat, is relatively new and innovative.
The top as well as the bottom of the oven may be heated depending on the location of the source of energy.
A conveyor belt may be used for the introduction and removal of the food products.
The advantages of these oven are: Food are cooked in a relatively short period of time.
The quality of certain foods is improved due to high temperature provided in a short period of time to the surface.
The ovens occupy relatively less space.
Due to the high temperatures that can be reached, most of the infrared ovens have self-cleaning mechanisms.
Either glass or metal pans may be used.
The outside environment does not get heated.
Owing to a shorter cooking time, these ovens are energy efficient.
Microwave Ovens Microwave ovens, like the infrared ovens, are based on the use of radiation to cook foods within the oven chamber.
Microwave are very short electromagnatic waves that have a wavelength between the ultrahigh bands and the infrared bands.
The wavelengths assigned to microwave ovens are 915 MHz, which are 13 in.
or 32 cm long, and 2450 MHz, which are 5 in.
or 12 cm long.
Megahertz (MHz) are a million cycles per second (cps).
The penetration of a 915-MHz wave is greater than that of a 2450-MHz wave.
Advantages of these ovens are: Food can be cooked faster.
The surrounding atmosphere is not heated.
The Ovens are very useful for reheating food portion in a very short period of time.
Several application make microwave ovens very useful.
For example, they can be used to thaw meats and reheat foods.
A combination of convection and microwave ovens is also being manufactured, which combines the attributes of both types of cooking methods Other Special applications of microwave oven include: Make sauces and gravies Warming syrups Drying bread crumbs and making croutons Drying hard cheese Heating wet towels for the customers Softening jellies and spreads Crisping potato chips Reheating coffee in cup Decontaminating flour and cereals
