Description

Technical Field

[0001] This utility model relates to the field of food production, and specifically to a chicken preservation device. Background Technology

[0002] In food production, a crucial step in chicken preservation is maintaining the meat's tenderness. Traditional chicken preservation methods often involve rinsing with cold water, but this method has the following shortcomings:

[0003] Rinsing with cold water only removes heat through brief contact between the water flow and the surface of the chicken, failing to quickly and evenly lower the internal temperature. For large pieces of chicken or whole chickens, the internal temperature drops slowly, affecting preservation and tenderization. Furthermore, after cooking, chicken leaves behind scum, debris, and other impurities on the surface and inside. Rinsing with cold water during preservation provides no effective means of removing these internal impurities.

[0004] Therefore, in order to overcome the shortcomings of existing technologies, it is necessary to design a chicken preservation device with a simple structure. Utility Model Content

[0005] This invention provides a chicken preservation device to address the problems of existing technologies.

[0006] The objective of this utility model can be achieved through the following technical solution: A chicken preservation device includes a cooling box, a hollowed-out rack, a lifting assembly, and a circulating spray assembly. The cooling box stores cold water, with a cold water inlet pipe on the upper right side and a drain pipe on the lower right side. A filter screen is installed inside the cooling box. The hollowed-out rack is installed at the lower end of the lifting assembly and can be raised and lowered within the cooling box. The circulating spray assembly includes a circulating pipe, a water pump, a spray frame, and spray heads. The spray frame is installed on the top of the hollowed-out rack, and the spray heads are installed at the lower end of the spray frame. The bottom of the circulating pipe is connected to the lower left side of the cooling box and is located below the filter screen. The upper end of the circulating pipe is connected to the spray heads, and the water pump is installed on the circulating pipe.

[0007] As a further improvement, a temperature sensor is provided in the middle of the inner side of the cooling box.

[0008] In a further improvement, the hollowed-out frame includes an upper plate, vertical rods, and a bottom plate. The upper end of the vertical rod is fixedly connected to the upper plate by bolts, and the lower end of the vertical rod is connected to the bottom plate by bolts. The bottom plate has an array of mesh holes. The lifting assembly includes an upper bracket and a cylinder. The cylinder is fixed to the upper bracket, and the piston rod of the cylinder is connected to the upper plate. The spray frame is fixed to the lower end of the upper plate.

[0009] In a further improvement, a fixing seat is provided inside the cooling box, and a slot is provided at the upper end of the fixing seat. The lower ends of both ends of the filter screen are provided with plug rods that match the plug slots.

[0010] As a further improvement, a control valve is provided on the drain pipe.

[0011] Compared with existing technologies, the beneficial effects of this novel chicken preservation device are as follows:

[0012] The lifting mechanism controls the perforated rack within the cooling tank to switch between soaking and spraying positions. Combined with a circulating spray system, cold water is drawn from the bottom of the cooling tank and sprayed evenly, forming a "soaking-spraying-filtration-recirculation" process. Soaking not only allows the chicken to evenly absorb the low temperature and remove internal impurities, but the impact of the spraying water also washes away external impurities, while the continuous low temperature further tenderizes the meat. The filter screen efficiently removes impurities, significantly improving cooling efficiency and impurity removal compared to traditional cold water rinsing. Attached Figure Description

[0017] The following describes the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.

[0018] Example 1

[0019] A chicken preservation device includes: a cooling box 1, a perforated rack 2, a lifting assembly 3, and a circulating spray assembly 4. The cooling box 1 stores cold water. The cooling box 1 has a cold water inlet pipe 11 on the upper right side and a drain pipe 12 on the lower right side. The cooling box 1 has a filter screen 13 inside. The perforated rack 2 is installed at the lower end of the lifting assembly 3 and can be raised and lowered within the cooling box 1. The circulating spray assembly 4 includes a circulating pipe 41, a water pump 42, a spray frame 43, and a spray head 44. The spray frame 43 is installed on the top of the perforated rack 2, and the spray head 44 is installed at the lower end of the spray frame 43. The bottom of the circulating pipe 41 is connected to the lower left side of the cooling box 1 and is located below the filter screen 13. The upper end of the circulating pipe 41 is connected to the spray head 44, and the water pump 42 is installed on the circulating pipe 41.

[0020] like Figures 1-2 As shown, the working principle of this utility model is as follows: Cylinder 32 drives the piston rod to extend downwards, causing the perforated rack 2 to descend into the cold water in the cooling tank 1. At this time, the chicken is placed on the bottom plate 23, and is fully in contact with the cold water through the mesh 231 of the bottom plate 23. The low temperature environment of the cold water is used to perform preliminary preservation treatment on the chicken, improving the tenderness of the meat. After soaking for a preset time, cylinder 32 retracts the piston rod, raising the perforated rack 2 above the cold water surface. At the same time, water pump 42 starts, drawing out the cold water from the bottom of the cooling tank 1 (located below the filter screen 13) through the circulation pipe 41, and transporting it to the spray head 44 of the spray rack 43, spraying the chicken surface with a uniform water flow. The spray water flow not only continuously cools the chicken, but also washes off the foam, debris and other impurities attached to the surface of the chicken through the impact force of the water flow, which then falls back into the cooling tank 1 with the water flow. After spraying, the water flow carries impurities down. When it passes through the filter screen 13, larger impurities are blocked by the filter screen, and the clean water continues to sink to the bottom of the cooling tank 1, forming a closed-loop system of "immersion-spraying-filtration-recirculation".

[0021] The soaking stage allows the chicken to absorb the low temperature evenly, while also removing internal scum and debris. In the spraying stage, the water flow and continuous low temperature further enhance the tenderizing effect. The directional rinsing of the spray water, combined with the interception of the filter screen, can quickly remove scum and debris from the surface of the chicken.

[0022] As a further preferred embodiment, a temperature sensor 5 is provided in the middle of the inner side of the cooling tank 1. This sensor monitors the cold water temperature in real time and transmits the data to the control system (not shown in the figure). When the temperature exceeds a preset threshold (e.g., 4°C), the control system can activate the cold water inlet pipe to add cold water.

[0023] As a further preferred embodiment, the perforated rack 2 includes an upper plate 21, vertical rods 22, and a bottom plate 23. The upper end of the vertical rod 22 is fixedly connected to the upper plate 21 by bolts, and the lower end of the vertical rod 22 is connected to the bottom plate 23 by bolts. The bottom plate 23 has an array of mesh holes 231. The lifting assembly 3 includes an upper support 31 and a cylinder 32. The cylinder 32 is fixed to the upper support 31, and the piston rod of the cylinder is connected to the upper plate 21. The spray rack 43 is fixed to the lower end of the upper plate 21. The vertical rods 22 are connected to the upper plate 21 and the bottom plate 23 by bolts, which facilitates disassembly and maintenance. The mesh holes 231 of the bottom plate 23 are arranged in an array, which can both support the chicken and ensure free flow of cold water.

[0024] As a further preferred embodiment, the cooling box 1 is provided with a fixing seat 14 inside, the fixing seat 14 has a slot 141 at its upper end, and the lower ends of both ends of the filter screen 13 are provided with plug rods 131 that match the plug slots 141. The plug-in installation makes the replacement time of the filter screen 13 shorter than that of traditional screw fixing, thus improving maintenance efficiency.

[0025] As a further preferred embodiment, the drain pipe 12 is equipped with a control valve 121. The control valve 121 (such as a ball valve or a solenoid valve) can control the opening and closing of the drain channel. When it is necessary to replace the cold water or clean the cooling tank 1, the control valve 121 is opened to drain the sewage under the action of gravity; after the replacement is completed, the valve is closed to ensure the sealing of the cooling tank 1.

[0026] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
