BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary barbecue apparatus, and more particularly to a commercial meat roasting apparatus capable of efficiently roasting large quantities of meat in a narrow space.

In general, an apparatus for barbecue cooking is provided with a heat source on the lower side or side, and the meat roasting plate is placed on or next to the heat source, and the meat is placed on the roasted meat plate to be cooked.

However, according to such a conventional yakiniku method, the meat is easily burned excessively during the roasting process, which is inconvenient to invert the meat frequently, and the oil generated when the grill is overheated or the meat is roasted in the charcoal There were various problems such as severe smoke and odor when falling on the back.

Accordingly, in recent years, a variety of rotary barbecue devices have been proposed as a method for evenly cooking a large amount of meat without burning meat and have been widely used commercially.

Such a device includes a rotary ocher charcoal barbecue roaster disclosed in Korean Utility Model Registration No. 227462.

The device of the present invention forms an ocher layer inside the body and forms a circular rotating plate on both sides of the ocher layer to form a second connecting shaft along the circumference of the rotating plate, and forms a roasting container to store meat on the second connecting shaft. And a second chain to connect the second connecting shaft and the second reduction gear, and a first connecting shaft is formed at the center of the rotating plate to form a first chain gear at one end of the first connecting shaft. When the first reduction gear and the second reduction gear are rotated separately after connecting the reduction gear to the first chain, the rotating plate and the roasting container are rotated separately so that only one part of the meat is excessively cooked due to the heat of the oven. It is configured to ripen.

However, in the barbecue roaster of such a structure, there is an inconvenience in replacing the hot roasted roaster because the roaster is installed inside the body, and the inconvenience of having to take out the ripe meat in the roaster one by one, and also due to the structural limitations. Due to the difficulty of baking a large amount of meat, there was a problem that it is difficult to digest the order of the guests who flock together at a certain meal time.

In view of this point, Korean Patent Publication No. 500950, Korean Patent Publication No. 508793, and Japanese Patent Publication No. 543410 propose a multi-stage rotary barbecue apparatus that can cook and provide a large amount of meat evenly.

The multi-stage rotary barbecue device of the above-described patent includes a firebrick including one or more combustion chambers having a space portion for accommodating a heat source, and a ash tray provided directly under the combustion chamber to receive ash falling from the combustion chamber. Fired by stacking; A rotating shaft installed in a vertical direction in the center of the oven and at least partially protruding to an upper portion of the oven; Drive means provided on one side of the oven including a motor for generating power by receiving external power to rotate the rotary shaft, and a transmission device for transmitting the power of the motor to the rotary shaft; A meat fitting rod for holding meat; Mounted at one point of the rotary shaft protruding from the top of the oven, while rotating the meat rod itself when the rotary shaft is rotated at the same time rotates the meat rod around the rotation axis, the meat rod is removable First rotating means that can be coupled to each other; Mounted on one point of the rotating shaft protruding from the upper part of the first rotating means to rotate the meat fitting rod itself while the rotating shaft rotates, and at the same time rotate the meat fitting rod around the rotating shaft, A second rotating means to which the rod can be detachably coupled; A first guide ring installed in a horizontal ring shape at the same height as the first rotation means along a circumference of the oven and for supporting and guiding a portion of the meat fitting rod mounted on the first rotation means; A second guide ring which is supported by a support installed along the circumference of the oven and installed in a horizontal ring shape at the same height as the second rotation means and supports and guides a part of the meat fitting rod mounted to the second rotation means; Each of the first rotation means and the second rotation means has a through hole formed at a center thereof, the rotation shaft is fitted into the through hole, and is fixedly installed regardless of the rotation of the rotation shaft.
