Abstract
Abstract A hotplate is fitted by means of a relatively wide and shallow mounting ring, whose outer edge rests on a mounting plate made from glass, ceramic or other materials. At its edge, the mounting ring is adhered to mounting plate using a thermally stable adhesive, which simultaneously forms a seal against cooked articles running through. The sheet metal insert ring covers the inner circumference of mounting a opening in the mounting plate and has an upper outwardly directed flange engaging over the seal. Simultaneously the seal, in conjunction with the insert ring, centers the hotplate in the mounting opening. A release ring can be inserted for releasing the hotplate.
