3.3 Operation Methods
3.3.1 Full load grilling
With full load grilling the rotisserie is loaded and the adjusted operation flow runs automatically for
the whole charge.
3.3.2 Revolving grilling
Revolving grilling we called that grilling procedure, when the spits are loaded deferred into the ma-
chine. This grilling procedure is especially popular in the catering business, because it allows pro-
ducing fresh grill products continuously. For this procedure special staff is no longer needed
(which was necessary yet), because we could realize a good idea in order to solve this problem. All
spits have a spit position number on the disc. When the spit is put into the rotisserie, the spit posi-
tion number will be activated on the control panel. After that the operator gets the information au-
tomatically, which of the spits is ready grilled.
3.3.3 Manual Grilling
In this mode all settings (Temperature, Time and Steam) can be set and run without prior pro-
gramming.
3.3.4 Holding
a) The Holding phase of CONVEX Rotisseries allows avoiding the products from drying out.
This is achieved by still heating. In this phase the machine stops the circulating air. A sepa-
rate cooling motor is started in order to cool down the technical components of the unit au-
tomatically.
b) Air humidification in the holding phase.
