This meat smoking machine can incompletely burn grains or cypress branches through the smoking assembly, generating a large amount of smoke to smoke meat, achieving energy saving, environmental protection, and high cleanliness.

[0004] However, the scheme does not include a smoke guide and smoke return structure, which causes the fumigation smoke to pass through the fumigation device in one go, resulting in a waste of smoke and making it difficult to guarantee the fumigation effect during the processing of live poultry.

[0005] To address this issue, a high-efficiency smoking device for live poultry processing is proposed, which has the advantages of smoke circulation and efficient smoking, thereby solving the problems mentioned in the background technology. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency fumigation device for live poultry processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency smoking device for live poultry processing, comprising a smoking box, wherein the bottom of the smoking box is connected to a smoke inlet pipe, and the top of the smoke inlet pipe is connected to a dispersing head, wherein a plurality of dispersing pipes are arranged around the side of the dispersing head, wherein the left side of the top surface of the smoking box is connected to an exhaust pipe, wherein a flow regulating valve is installed on the surface of the exhaust pipe, and a return smoke pipe connected to the exhaust pipe is provided above the flow regulating valve, wherein a first motor is fixed on the right side of the top surface of the smoking box, and a transmission is wound around the output end of the first motor. The drive belt has a perforated plate welded to the inner wall of the smoking box above the dispersing head. A rotating rod is mounted on the top surface of the perforated plate via a bearing. The top of the rotating rod passes through the smoking box and is wound around the drive belt. A smoke pipe connected to the smoking box is provided at the bottom end of the smoke return pipe. A second motor is fixed to the end face of the smoke pipe. An impeller is fixed to the output end of the second motor extending into the smoke pipe. A suspension plate is fixed to the upper surface of the rotating rod. Several suspension strips are welded around the bottom surface of the suspension plate, and several hooks are installed on the bottom surface of each suspension strip.

[0008] As a further description of the above technical solution: an oil collection plate is welded to the lower surface of the rotating rod, and a number of fan-shaped oil collection grooves are opened around the top surface of the oil collection plate, and the number of oil collection grooves are respectively located below a number of suspension bars.

[0009] As a further description of the above technical solution: the top surfaces of both the dispersing head and the dispersing tube are provided with a number of second through holes, and the dispersing head and the dispersing tube are connected.

[0010] As a further description of the above technical solution: the surface of the oil collecting plate is uniformly provided with a number of first through holes, and the number of first through holes and the number of oil collecting grooves are staggered.

[0012] As a further description of the above technical solution: the inner wall of the fumigation box is coated with an oleophobic layer, and the material of the oleophobic layer is an organosilicon coating.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the inner diameter of the exhaust pipe is reduced by a flow regulating valve, and then the second motor is started to drive the impeller inside the chimney to rotate. Under the action of the pressure difference between the front and back of the impeller, the smoke discharged from the exhaust pipe is drawn into the chimney through the return pipe and then blown into the smoking box by the impeller, realizing the circulation of smoke in the smoking box. On this basis, by setting multiple dispersion pipes around the side of the dispersion head of the inlet pipe, combined with the live poultry products hung on the hanging plate by hooks and the hollow plate with several holes, it is beneficial to increase the utilization rate of smoke and the dispersion of smoke entering the smoking box, and also improve the smoking effect and uniformity of live poultry products.

[0015] In this invention, by starting the first motor, the output end of the first motor drives the rotating rod to rotate under the action of the transmission belt. This causes the rotating rod to drive the suspension plate mounted on its surface to rotate at a low speed, improving the uniformity of smoking of live poultry products on the hook of the suspension plate. On this basis, an oil collection plate is welded to the lower surface of the rotating rod corresponding to the suspension plate, and several fan-shaped oil collection grooves are formed around the top surface of the oil collection plate. This allows the grease that drips out during the smoking stage to fall into the oil collection grooves, avoiding the situation where grease drips directly into the smoking box, causing blockage of the smoke inlet pipe port and making subsequent cleaning difficult.
