5.2.5 Notes and tips
WARNING! Danger of burns!
When preparing of food or liquids, filled into containers, it is necessary to pay
attention to a possible escape of it both during cooking and during withdrawal
of the container from the convection oven.
In the case that the convection oven is located on fermentation cabinets,
stainless steel tables or other ovens, it is not recommended, to use higher
fitted shelves than the shelves, where the user can look into the container.
• When grilling or frying of food, it is necessary to place a container on the bottom of
the cooking space to catch fat or juices.
• For a perfect and uniform cooking of food, we recommend to use of non-high sheets
or GN containers, so that a good and sufficient air circulation is ensured. A minimum
distance of 2 cm must be maintained between the upper sheet and the food.
• Do not overfill the sheets, GN containers, distribute the cooking product evenly in
order to achieve a satisfactory result.
• Pay attention to the correct use of the core temperature sensors: Introduction in the
thickest point of the food from the top to down until reaching the centre with the top
of the core temperature sensors.
• In order to compensate the impact of heat loss by opening the convection oven door
for introducing food, it is recommended to preheat at least 30 °C above the
temperature intended for cooking.
• If during cooking interventions on the food are needed, the convection oven door
may be opened only as short as possible in order to avoid that the temperature
inside the cooking space will be so reduced that the success of cooking is impaired.
ATTENTION: we recommend to open the door in two stages: the convection
oven doors to keep half opened (3 - 4 cm) for 4 - 5 seconds and then fully open
at first. Through this it can be avoided that hot steam and the heat cause
disturbances or burns in the convection oven.
THAWING
The convection oven can be used to speed up the thawing process of the food to be
cooked using the recirculated air at room temperature or lower temperature (depending
on the size and type of product to be defrosted). Thus the frozen foods can be thawed
quickly and without loss of flavour or change in appearance.
- 59 -
STEAMING
The steam system is suitable to cook softer all types of food. In addition, it is suitable
for rapid defrosting, warming up of the food without drying or hardening it and natural
desalting of food
pickled in salt.
The combination of function of steaming and the traditional function allows the
flexibility of the application together with energy and time savings. Simultaneously,
the nutritional content and taste of the food are kept unchanged.
The water injected to the fan is atomised and by the passage through the heating
plate, it is transformed into steam.
ATTENTION: In order to enable the function of the steaming in the satisfactory
manner, it is necessary to set the temperature to at least 80 °C - 100 °C. At lower
temperatures, it is difficult to produce the steam and the most of water collects at
the bottom in the cooking space of the convection oven.
Moreover, preheating of the convection oven to the desired temperature is
necessary for a good cooking before the steaming is activated.
PREHEATING
To compensate for the effects of heat loss by opening the convection oven door
during insertion of food inside the cooking space, it is recommended to preheat to
at least 30 ° C above the temperature envisaged for cooking.
