Description

Peking Duck Roasting Machine {ROTARY TYPE ROAST MACHINE OF BEIJING DUCK}

The present invention relates to a Peking duck rotary roasting device, and more particularly, providing a rotating meat (duck, chicken, pork) roasting device, but improving the cooking quality, shortening the cooking time, and providing an energy saving effect. It relates to a rotary meat roasting device, in particular a Peking duck rotary roasting device.

In general, a variety of meats such as chicken, duck and pork contain a lot of oil, so the taste remains even when baked, and at the same time, there is a problem of promoting obesity due to excess calories. Roasting devices have been developed and used in various ways in recent years.

In the meat roasting apparatus, there are a method in which the heat generated from a heat source directly heats the meat, and a method in which the meat is placed on a grilling plate that is directly heated by the heat generated from the heat source and indirectly heated. Since the part is heated directly, when the meat is cooked to the inside of the meat, the surface part is burnt black, and in the latter part, heat from the grilling plate heated by the heat source cannot be transmitted evenly to the whole meat, so only the part that is in contact with the grilling plate is heated intensively. Therefore, in order to cook the meat evenly, there was an inconvenience that the meat had to be turned over frequently.

In order to solve the above inconvenience, in recent years, a rotary meat cooking device is used in which the meat is hung inside the grilling room while rotating while applying heat. For example, Korean Utility Model Registration No. 0214923, Korean Registered Patent No. No. 10-0822025 and Korean Patent Registration No. 0307346 have been proposed.

In the conventional rotary meat cooking apparatus as described above, a ring is installed inside the grilling chamber, and the meat is heated by a heater while rotating the ring by a reduction motor and a belt, and oil generated from the meat is collected in a separate container. As it became, it was able to give the light taste of the meat.

However, the existing rotary meat cooking apparatus that rotates around a heat source has a problem that only one side of the meat facing the heat source is heated while one side is burned and the other side is less cooked.

In order to solve the above problems, a rotary meat cooking device has been proposed that includes an orbiting means that rotates around a heat source and a rotating means that allows meat placed in each ring to rotate by itself. On the other hand, there was a problem that the cooking time was too long.

In addition, the existing rotary meat cooking apparatus was easy to cook chicken, pork, etc., but in the case of ducks with a lot of oily and rich meat quality, the outside is burnt and the inside is less cooked, or due to too long cooking time, all moisture evaporates and the meat is dried. There were many difficulties in cooking with a barbecue type, such as being tough and tough.

One of the reasons why the duck barbecue is particularly difficult to cook is that the continuous rotation of the meat promotes cooling after heating the meat, and it is analyzed that excessive evaporation of moisture occurs before the meat is cooked. It was required to develop a device that properly balances the target duck's turning point.

Republic of Korea Utility Model No. 0214923 (Registered on December 14, 2000) Korean Patent Registration No. 0822025 (Registered on April 7, 2008) Republic of Korea Patent Registration No. 0307346 (2001.08.20 registration)
