Description

Technical Field

[0001] The invention relates to the field of food processing, and in particular to a continuous meat and poultry roasting machine. Background Art

[0002] China's roast duck industry is experiencing a booming development momentum. According to industry data, the industry's compound annual growth rate remained at 6.5% from 2019 to 2024. This patent involves a continuous meat and poultry roasting machine that aims to improve the mechanized production efficiency of roast duck and other meat and poultry and reduce production costs. Compared with the batch production of traditional roast duck ovens, the research and development of continuous meat and poultry roasting machines can change batch production to continuous production, which will greatly improve production efficiency. This involves a continuous meat and poultry roasting machine.

[0003] For example, patent number CN220916350U discloses a roast duck oven with uniform heating. The equipment cooperates with the connecting plate, inner ring gear, rotating gear, central gear, telescopic rod and inclined plate so that the roast duck fixed in the middle of the output end of the telescopic rod can not only rotate back and forth but also move up and down during the roasting process, so that the roast duck is heated evenly from top to bottom and left to right. The roasting efficiency of the equipment is not high, and since multiple gears are running all the time when the equipment is running, lubricating fluid needs to be added in time, otherwise the parts will be damaged.

[0004] For example, patent number CN218304574U discloses an automated oven that can batch roast ducks in and out of the oven, including a vertical oven body, a take-in and put-out opening for taking roast ducks on the top of the oven body, an oven cover on the take-in and put-out opening, a side shift seat and a side shift track, an annular hanging frame and a connecting rod are arranged under the oven cover, and the side shift seat drives the oven cover to a cooking position opposite to the oven body and a take-in and put position staggered with the oven body. The above scheme improves the efficiency of taking and putting roast ducks, but due to the particularity of its structure, the side shift track needs to be fixed in place for use, and its space utilization rate is not high.

[0005] For example, patent number CN217471087U discloses a roast duck oven, including an oven body, a roast duck cavity, a sealed door, a heating device and a rotating rack. A control box for controlling the heating device and the rotating rack is provided on the oven body, and the control box is detachably arranged on the oven body. The heating device includes a plurality of heating tubes and heat conducting members, and one end of the heating tube is arranged at the bottom center of the roast duck cavity, and the other end is wound up and down on the heat conducting member. The roast duck cavity of the device stores heat evenly, but the roast duck does not complete its rotation during the revolution during the roasting process, making it difficult to achieve even roasting.

[0006] For example, patent number CN221711051U discloses a roasting device for roast duck production, including an oven, a rotary machine, a power rod, a drain valve and an isolation door. The device uses a power rod. When the rotary machine is started, the power rod at the output end rotates on the bearing surface, and the bottom is fixed by fitting the hook and the hook nut, and a fixing rod is inserted in the reserved groove of the hook and the hook nut to fix it, so that the rotary machine drives the rotating cage to rotate at a uniform speed, but its single output is small and continuous roasting cannot be performed. Summary of the invention

[0007] The technical problem to be solved by the present invention is that it is difficult to achieve continuous roasting during the roasting process of meat and poultry, and the design needs to overcome the problem of improving the efficiency of the roasting process and roasting uniformity.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a continuous meat and poultry roasting machine, comprising a continuous feeding and discharging system, a double-row chain transmission and rotation system and an auxiliary system. It is characterized in that the continuous feeding and discharging system is composed of a feeding port, a discharging port, a multi-point heating system and a rectangular wave upper chain, the multi-point heating system is composed of heating groups 1-11; the auxiliary system is composed of a smoke exhaust mechanism, an oil collection mechanism, a frame, a motor and a maintenance door. The double-row chain transmission and rotation system consists of a rectangular wave upper chain, sprocket I, a rectangular wave lower chain, sprocket II and a hanging mechanism. The double-row chain transmission and rotation system can achieve uniform baking of the material. The rectangular wave upper chain is meshed with sprocket I, and the rectangular wave lower chain is meshed with sprocket II. The sprocket I and sprocket II are driven to rotate by a motor. The sprocket I and sprocket II have different numbers of teeth, so that the rectangular wave upper chain and the rectangular wave lower chain have a speed difference when they move forward; a sprocket that can mesh with sprocket II is arranged under the hanging mechanism. The material moves forward with the rectangular wave upper chain, and the rectangular wave lower chain and the sprocket of the hanging mechanism are meshed by gravity to achieve the self-rotation of the material when it moves forward, and then cooperate with a multi-point heating system to achieve uniform baking.

[0009] A continuous meat and poultry roasting machine, characterized in that the continuous feeding and discharging system enables the entire roasting process to be carried out continuously, specifically as follows: workers hang materials at the feeding port, and realize the continuous forward movement of materials inside the roasting room through rectangular wave transmission. At the same time, a multi-point heating system is arranged around the rectangular wave upper chain, and the rectangular wave upper chain is driven by a motor to move forward at a uniform speed, so that it moves to the discharge port and the roasting ends. The worker takes the finished product at the discharge port, and a single roasting cycle ends. A component that can be hung by the hanging mechanism is added to a single link of the rectangular wave upper chain, and its rectangular wave design increases the roasting stroke.

[0010] Compared with the prior art, the beneficial effects of the present invention are: for the hanging device, instead of fixing the raw dough near the heat source like the traditional baking method, the raw dough is designed to be hung on a special moving chain, and its own movement during the baking process realizes rotation and revolution, so as to achieve uniform and sufficient baking.

[0011] For the design of the multi-point heating system, a multi-angle and omnidirectional heating source design is adopted to save the internal space and volume of the machine. The route of the raw material cannot be kept in a straight line, so a single heating source cannot achieve a good heating effect. Therefore, multiple heating sources are designed to be evenly arranged along the route of the raw material. This design can achieve a good baking effect while saving the space and volume of the machine.

[0012] For the design of the smoke exhaust mechanism, multiple fans with air ducts are designed. Important transmission components and hanging mechanisms are distributed on the upper part of the continuous meat and poultry roasting machine. Oil smoke and exhaust gas are inevitably generated during the roasting process. In the process of these oil smoke and waste rising, they will inevitably contaminate the upper precision components. Therefore, a protective layer is designed. When the conventional fan exhausts the oil smoke, the oil smoke will diffuse outside the fan. Therefore, a fan with an air duct is designed to ensure that the oil smoke and exhaust gas will not diffuse and contaminate other components before being discharged from the machine.

DETAILED DESCRIPTION

The motor 22 drives the sprocket I 15 and the sprocket II 17 to rotate. The sprocket I 15 and the sprocket II 17 have different numbers of teeth, so that the rectangular wave upper chain 14 and the rectangular wave lower chain 16 have a speed difference when they move forward; a sprocket that can mesh with sprocket II 17 is arranged below the hanging mechanism 18. The material moves forward with the rectangular wave upper chain 14, and the rectangular wave lower chain 16 and the sprocket of the hanging mechanism 18 use gravity to mesh to realize the self-rotation of the material when it moves forward, and then cooperate with the multi-point heating system to make the baking uniform.

[0020] A continuous meat and poultry roasting machine, characterized in that the continuous feeding and discharging system enables the entire roasting process to be carried out continuously, specifically as follows: a worker hangs the material at the feed inlet 1, and realizes the continuous forward movement of the material inside the roasting room through rectangular wave transmission. At the same time, a multi-point heating system is arranged around the rectangular wave upper chain 14, and the rectangular wave upper chain 14 is driven by the motor 22 to move forward at a constant speed, so that it moves to the discharge port 2 and the roasting ends. The worker takes the finished product at the discharge port 2, and a single roasting cycle ends. A component that can be hung by the hanging mechanism 18 is added to a single chain link of the rectangular wave upper chain 14, and its rectangular wave design increases the roasting stroke and improves the space utilization rate.

[0021] In actual use: The motor 22 provides power to the sprocket I15 and the sprocket II17 through the hollow shaft. The rectangular wave upper chain 14 and the rectangular wave lower chain 16 mesh with the sprocket I15 and the sprocket II17 and move forward at a constant speed. The material is hung on the hanging assembly of the rectangular wave upper chain 14 to drive it to move at a constant speed in the baking room, and the sprocket on the hanging mechanism 18 meshes with the rectangular wave lower chain 16 to achieve the effect of self-rotation. After preheating, the temperature of the multi-point heating system in the baking room is always constant within the required range, and the distance between each heating group 1-11 (3-13) and the material is always consistent during movement. The dripping of grease and the discharge of smoke during the baking process are completed by the oil collection mechanism 20 and the smoke exhaust mechanism 19. The oil collection mechanism 20 is arranged under the whole machine. During the movement of the whole material, the grease dripping due to baking enters the oil collection cylinder through the oil unloading pipe on the oil collection mechanism 20, and in order to facilitate the cleaning work during the production process, the oil collection mechanism 20 is set to be detachable. The oil smoke generated during the baking process is discharged through the air duct with a filter screen of the smoke exhaust mechanism 19.

[0022] When the device is running: First, the staff turns on the multi-point heating system for preheating. After preheating, the temperature is always constant within the required range. Then, the motor 22 is started to operate the double-row chain transmission and rotation system. Then, the prepared materials are hung on the hanging mechanism 18 at the entrance, and the hanging mechanism 18 is hung on the hanging assembly of the rectangular wave upper chain 14. The motor 22 drives it to move forward at a uniform speed in the baking room, and the engagement of the sprocket on the hook 18 and the rectangular wave lower chain 16 achieves the effect of self-rotation. The dripping of grease and the discharge of smoke during the baking process are completed by the oil collection mechanism 20 and the smoke exhaust mechanism 19. After baking, the workers remove the baked products at the discharge port 2, and at the feed port 1, the workers regularly hang new materials according to the set intervals, and the cycle is repeated to achieve uninterrupted baking.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several changes and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
