It is therefore proposed that the device according to the invention on the one hand has a metal mesh burner with which a particularly high heat development is possible. These high temperatures cause the meat to be grilled only for a very short and very precise period of time. However, for this reason, the respective grill - periods are very short, for example, below one minute. For this reason, deviations from the ideal grilling time have a strong effect on the result of the grilling process.

Thus, it is additionally proposed that the device has a movable storage device to bring the grilled meat very quickly from the heating area can. In this way, the desired grilling times can be kept very well.

It should be noted, however, that the electrically operated lifting device can also be used independently of the gas braided burner described here.
