Abstract

The present invention aims at providing duck roasting process and roaster with homogeneous heating, homogeneous product appearance and color, standard operation and no pollution. The technological process features that the prepared duck is roasted in airflow of 120-150 deg.c temperature and 5-20 m / s speed for 30-60 min inside an airflow impacted duck roaster. The roaster includes roasting chamber with nozzles on two sides and waste air recovering channel, duck suspender, fan assembly and heater in the lower part of the roasting chamber, and rotating unit in the top center of the roasting chamber. The present invention has the features of homogeneous heating, no flame, no pollution, homogeneous color of the roasted product and standard operation. The present invention may be also used in producing roasted chicken, roasted sucking pig, roasted whole sheep, etc.

Description

technical field [0001] The invention relates to a gas jet impingement roast duck process and device, and the device is also suitable for roast chicken, roast suckling pig, roast whole lamb and the like. Background technique [0002] "Beijing Roast Duck" has a long history. As early as the Southern and Northern Dynasties, "Food Treasures" has recorded "Roasted Duck". "Beijing Roast Duck" is roasted with an open fire, which makes the duck taste crisp and fragrant, fat but not greasy, and is praised by people. At present, "Beijing Roast Duck" has hanging oven roasting, braised oven roasting and spit roasting. Hanging oven and braised oven are the most common. The difference between hanging oven roasting and braising oven roasting is that the former generally uses hard fruit wood such as dates, peaches, and apricots as fuel to roast directly with an open fire, while the latter roasts with a dark fire with the oven door closed. The main problems of the traditional baking techn...
