Technical Field

[0001] This utility model relates to the field of food drying technology, and in particular to an internal circulation drying device for roast duck and roast goose. Background Technology

[0002] In the processing of poultry meat products such as roast duck and roast goose, air drying is one of the core processes that determines the quality of the finished product. By using a stable airflow to remove the surface moisture of the ingredients, the skin can be made to have a firm texture. At the same time, it avoids the difference in taste caused by uneven moisture distribution in the meat, which directly affects the crispness, flavor stability and shelf life of the product.

[0003] With the large-scale and standardized development of the food industry, the industry's requirements for air-drying equipment are increasing. It is necessary not only to achieve efficient moisture removal, but also to ensure the uniformity of the air-drying process, the controllability of the environment (such as humidity and cleanliness), and the convenience of equipment operation and maintenance, so as to meet the strict requirements for product consistency in mass production.

[0004] However, existing roast duck and goose air-drying equipment has many technical defects: First, it lacks a closed internal circulation airflow system and relies more on open or semi-open air supply, which is easily affected by the external environment, resulting in humidity accumulation inside the cabinet and low air-drying efficiency; Second, the racks are mostly fixed structures, and the airflow direction is unidirectional, which leads to uneven airflow to different parts of the food, often resulting in local over-drying or under-drying. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an internal circulation air-drying device for roast duck and roast goose, which solves the problems of low air-drying efficiency and uneven air exposure of food.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an internal circulation air drying device for roasted duck and goose, comprising a cabinet body and a cabinet shell. A return air trough is provided on the right side wall of the cabinet body, and a return air duct is connected to the return air trough.

A shaft is installed inside the cabinet body, and rotating wheels are installed at both ends of the shaft. The two rotating wheels are respectively installed at the top and bottom of the cabinet body. A hanging bracket is sleeved on the shaft, and a hanging ring is rotatably installed at the bottom of the hanging bracket.

[0007] As a further description of the above technical solution: the return air duct, dehumidification filter cartridge, air supply fan and air supply duct are all installed in the cavity formed between the cabinet body and the cabinet shell.

[0008] As a further description of the above technical solution: a metal oil separator is installed at the inlet of the return air duct.

[0009] As a further description of the above technical solution: the dehumidifying filter cartridge has a drawer-type structure design and is connected to the return air duct by a snap-fit. Silica gel desiccant and activated carbon are sequentially arranged in the dehumidifying filter cartridge.

[0010] As a further description of the above technical solution: the bottom end of the shaft is connected to a drive motor via a belt.

[0011] As a further description of the above technical solution: the blowing nozzle is located on the left side wall of the cabinet, and the angle is adjustable.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5 An embodiment of this utility model provides a roast duck and roast goose internal circulation air drying device, including a cabinet body 1 and a cabinet shell 2. The right side wall of the cabinet body 1 is provided with a return air trough 3, the return air trough 3 is connected to a return air pipe 4, the other end of the return air pipe 4 is connected to a dehumidifying filter cartridge 5, the other side of the dehumidifying filter cartridge 5 is connected to a blower 7 through a pipe, the output end of the blower 7 is connected to a blower 8, the other end of the blower 8 is connected to a blower nozzle 9, a shaft 10 is installed inside the cabinet body 1, and two rotating wheels 11 are installed at both ends of the shaft 10. The two rotating wheels 11 are respectively installed at the top and bottom of the cabinet body 1. A hanging bracket 12 is sleeved on the shaft 10, and a hanging ring 13 is rotatably installed at the bottom of the hanging bracket 12.

[0028] The return air duct 3, return air pipe 4, dehumidifying filter cartridge 5, air supply fan 7, air supply pipe 8, and air nozzle 9 form a complete internal circulation airflow system, realizing the circulation, purification, and directional delivery of air inside the cabinet 1. At the same time, through the cooperation of the rotating wheel 11 and the shaft 10, the hanging rack 12 can be manually rotated when hanging food, making it convenient to hang food on the hanging rack 12. During air drying, the rotatable hanging ring 13 makes the food rotate under the action of the air nozzle 9, so that the surface of the food is evenly exposed to air, solving the problem of uneven air exposure of food, improving air drying efficiency, and ensuring air drying consistency.

[0029] Specifically, the return air duct 4, dehumidification filter cartridge 5, air supply fan 7, and air supply duct 8 are all installed in the cavity formed between the cabinet body 1 and the cabinet shell 2; the interlayer space is used to achieve the concealed installation of functional components, save the internal space of the cabinet body 1, avoid the functional components occupying the food drying area, and protect the ducts and fan through the cabinet shell 2 to reduce external collisions or contamination.

[0030] Specifically, a metal grease trap is installed at the inlet of the return air duct 3; its mesh structure intercepts grease particles produced by food during the drying process, preventing grease from entering the return air duct 4, reducing grease contamination of the dehumidification filter cartridge 5 and the fan, and reducing maintenance frequency.

[0031] Specifically, the dehumidifier filter cartridge 5 has a drawer-type structure and is connected to the return air duct 4 via a snap-fit ​​connection; it can be quickly pulled out and disassembled for easy replacement of the internal filter material; the snap-fit ​​connection ensures a reliable seal between the dehumidifier filter cartridge 5 and the return air duct 4, preventing airflow leakage from affecting the internal circulation efficiency; silica gel desiccant and activated carbon are sequentially arranged inside the dehumidifier filter cartridge 5; the silica gel desiccant adsorbs moisture in the circulating air to reduce humidity, while the activated carbon adsorbs odors and tiny impurities; through this dual purification effect, a low-humidity, odorless drying environment is maintained inside the cabinet 1, preventing food from being affected by high humidity and thus reducing drying efficiency.

[0032] Optionally, the bottom end of the shaft 10 is connected to a drive motor 6 via a belt. After hanging the food to be dried on the rack 12, close the cabinet door 14 and turn on the drive motor 6. Under the action of the drive motor 6, the rack 12 is rotated. The rotatable hanging ring 13 causes the food to rotate under the action of the air blower nozzle 9. The revolution of the rack 12 and the rotation of the hanging ring 13 make the surface of the food evenly exposed to air, solving the problem of uneven air exposure caused by the traditional fixed rack 12, further improving the drying efficiency while ensuring the consistency of drying.

[0033] Specifically, the blower nozzle 9 is located on the left side wall of the cabinet 1, and its angle is adjustable. When the blower nozzle 9 is tilted, the airflow acts more evenly on all surfaces of the food, solving the problem of insufficient local drying caused by airflow in one direction.

[0034] Specifically, there are several air blowers 9 arranged in multiple rows, with multiple nozzles in each row, each corresponding to a layer of hanging rack 12. The multiple rows of air blowers 9 correspond one-to-one with the multiple layers of hanging rack 12. Each row of nozzles directs airflow to the food on the corresponding layer, ensuring that the food on each layer of hanging rack 12 receives a stable airflow. This avoids uneven airflow distribution caused by height differences in the multiple layers of hanging rack 12, ensuring that the drying speed and effect of each layer of food are consistent, and improving the space utilization and batch processing capacity of the equipment.

[0035] Specifically, there are several racks 12, and the spacing between adjacent racks 12 is sufficient for hanging roast ducks and roast geese; ensuring that roast ducks and roast geese do not touch each other after being hung, leaving enough gaps for airflow and improving the utilization rate of cabinet space; avoiding food from blocking or sticking together, and ensuring that the surface of each food can fully contact the airflow.

[0036] Specifically, there are several hanging rings 13, which are evenly arranged circumferentially below the hanging rack 12; this makes the food hanging points symmetrically distributed, ensuring that the hanging rack 12 is balanced when rotating, and avoiding the hanging rack 12 from getting stuck due to uneven force; and the airflow environment of each food item is consistent; the food is suspended on the evenly distributed hanging rings 13, and the probability of being exposed to wind in each direction is the same, further improving the consistency of air drying.

[0037] Specifically, a viewing door 14 is installed on the front side of the cabinet 1, and a sealing strip is installed around the viewing door 14. The viewing door 14 uses transparent material to allow real-time observation of the drying process, which makes it easy for operators to monitor the drying progress of the food and adjust the parameters in a timely manner. The surrounding sealing strip enhances the sealing of the cabinet 1, reduces leakage of internal circulating airflow, and maintains the internal humidity and airflow stability of the cabinet 1.

[0038] Working principle: When in use, hang the roast duck or goose on the hanging ring 13 and close the viewing cabinet door 14; start the blower 7 and drive motor 6, and the air in the cabinet 1 enters the return air duct 4 through the return air duct 3 (metal oil separator to filter grease), and then passes through the dehumidification filter cartridge 5 (silica gel desiccant to remove water and activated carbon to remove odor); the purified air is delivered to the blower nozzle 9 through the blower 7 and the air duct 8, and the drive motor 6 drives the hanging rack 12 to rotate. At the same time, the rotatable hanging ring 13 rotates under the action of the blower nozzle 9. The rotation of the hanging rack 12 and the rotation of the hanging ring 13 achieve uniform air drying; the airflow circulates in the cabinet, continuously completing the air drying, dehumidification and purification process. The operator can observe the air drying progress through the viewing cabinet door 14, and turn off the equipment when it is completed.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
