The induction plate: features and differences from ceramic glass
The induction plate and the ceramic glass plate are both common in modern restaurant kitchens but have different aspects in the way they cook and are used to prepare food. The differences between these two cooking methods mainly concern the mode and speed of heat distribution, energy efficiency and temperature control.
Comparing plates: how do they work
The induction plate is powered by a magnetic field that allows the pot or pan to be heated directly. Under the glass surface of the hot plate is a copper coil that produces a high-frequency magnetic field when activated. When a pot or pan is placed on top of the cooking surface, the change in the magnetic field generates an electric current that runs through the metal bottom of the pot, producing heat. This process allows the food to be heated quickly and efficiently, while keeping the rest of the surface relatively cool to the touch. It only takes a few minutes to boil the water to prepare an excellent pasta.
The ceramic glass plate in turn works by heating the glass itself, which then transfers heat to the pan. Underneath the ceramic glass plate, there are electric heating elements. As they heat up, they transmit heat to the surface and then to the pan. This process therefore requires an extra step in heat transmission and, consequently, more time than with the induction plate.
Differences in cooking, energy saving and type of equipment
The induction plate offers precise temperature control. It is therefore ideal for the cooking of delicate foods and for maintaining constant heat, which is only produced in the area where the pan is in contact with the plate. It is also energetically preferable: the heat generated is not dispersed into the surrounding environment.
The ceramic glass plate has not as high a temperature accuracy as the induction plate, but is still able to maintain constant temperatures for most preparations and retains heat even after cooking. It therefore takes longer to use and is less efficient in terms of energy savings.
However, the induction plate only works with pans where a magnetic field can be generated. Therefore, it is necessary to use stainless steel, cast iron or aluminium pans with a magnetic bottom. The glass ceramic plate, on the other hand, is compatible with almost all types of pans.
Induction or ceramic glass plate? How to choose
Choosing the right plate is very important for a restaurant or bar kitchen. It means improving the preparation of dishes, better time management and optimising energy consumption. Desco’s wide range of cooking equipment is among the most reliable, efficient and safe. Products are available in various sizes, with 2 or 4 burners, with advanced technical and functional features.
Desco glass-ceramic cooker models are characterised by a 60/10 thick worktop. The smooth surface allows pots to be moved quickly from one work station to another and makes cleaning easier. An indicator light also signals the presence of residual heat up to 60°C.
Induction plates have a very high efficiency that reaches almost 100%. The work area is only activated when the pan is placed on the work surface and quickly heats the food. The range includes 2- and 4-zone cookers and the Wok version. The models are equipped with a sensor that detects the compatibility of pots and pans, to avoid using cookware that is not suitable for this type of cooking.
