Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, and in particular relates to a rapid cooling and freshness-locking device for pre-prepared grilled fish dishes. Background Technology

[0002] Pre-cooked grilled fish dishes are ready-to-eat or simple-cooking foods made primarily from fresh fish. After pretreatment, marinating, high-temperature grilling, and standardized seasoning, they are preserved through specific packaging and cold chain technology.

[0003] In the industrialized production process of pre-cooked grilled fish, "cooling and freshness preservation" is a crucial link between "grilling and processing" and "packaging and storage," directly affecting the food safety, shelf life, and taste of the product. Currently, the industry mainly uses two cooling methods for freshly grilled fish: one is natural cooling, where the grilled fish is laid flat on the work surface and cooled by natural heat dissipation from the ambient air. This method requires no equipment investment, but the cooling efficiency is extremely low. It usually takes a long time for a single batch of grilled fish to cool completely to the safe temperature before packaging, and it is greatly affected by the ambient temperature and humidity of the workshop. In the high temperatures of summer, the cooling time is further extended, making it difficult to adapt to the needs of large-scale, high-paced production. The other method is ordinary fan cooling, which uses industrial fans to blow air onto the grilled fish to accelerate heat dissipation. Although it can shorten the cooling time to some extent, the grilled fish near the fan outlet cools down quickly, while the grilled fish further away from the outlet cools down slowly, resulting in inconsistent cooling progress for a single batch of grilled fish. More importantly, the grilled fish is in the dangerous temperature zone where microorganisms multiply most rapidly for a long time, making it extremely easy for bacteria to grow, which increases the risk of product spoilage.

[0004] To address these issues, we provide a rapid cooling and freshness-locking device for pre-prepared grilled fish dishes. Utility Model Content

[0005] The purpose of this invention is to provide a rapid cooling and freshness-locking device for pre-prepared grilled fish. By using a fixed frame distributed alternately in the cooling assembly and a centrally symmetrical ventilation pipe group, combined with a cold air blower for continuous cooling, a sealed cooling chamber for cold preservation, and a layered support plate to increase the cooling capacity per batch, the problem of long cooling time for single batches of grilled fish is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a rapid cooling and freshness-locking device for pre-cooked grilled fish, including a base frame; a cooling chamber is fixedly connected to the top of the base frame, and the interior of the cooling chamber is provided with a cooling component for cooling the grilled fish, a support plate for supporting the grilled fish, and an oil collection box for receiving the oil dripping from the grilled fish. A cold air fan for providing cold air to the cooling component is fixedly connected inside the base frame, and multiple air outlets are opened on both sides of the cooling chamber. Multiple guide rails and support frames are fixedly connected to both sides of the inner wall of the cooling chamber. The support plate is slidably connected to the inside of the corresponding two guide rails, and the oil receiving box is slidably connected between the corresponding guide rail and the support frame. The cooling assembly includes multiple fixed frames that are fixedly connected inside the cooling chamber, and the fixed frames, the support plate and the oil receiving box are distributed alternately. The interior of the fixed frame is provided with two ventilation pipe groups that are centrally symmetrically distributed. The ventilation duct assembly includes multiple horizontal pipes fixedly connected inside the fixed frame and a connecting pipe perpendicular to the horizontal pipes. The connecting pipe is connected to multiple horizontal pipes. Multiple air outlets are installed at equal intervals at the bottom of the horizontal pipes. The cooling chamber is provided with a vertical pipe connected to the output end of the air cooler, and the vertical pipe is connected to the connecting pipe.

[0007] The present invention is further configured such that a cabinet door is rotatably connected to the front of the cooling chamber, and a controller for controlling the operation of the air cooler is fixedly connected to the outside of the cabinet door.

[0008] The present invention is further configured such that a timer alarm is fixedly connected to the top of the cooling chamber, and the timer alarm is electrically connected to the controller.

[0009] The present invention is further configured such that filters corresponding to the air outlets are fixedly connected to both sides of the oil receiving box.

[0010] The present invention is further configured such that the top of the bearing disk has a honeycomb mesh structure, and multiple rollers are rotatably connected to both inner sides of the bearing disk, and the rollers roll inside the corresponding guide rails.

[0011] The present invention is further configured such that a second handle is rotatably connected to the front of the oil receiving box, and a first handle is rotatably connected to the front of the bearing plate.

[0012] The present invention is further provided that the front of the cabinet door is provided with an observation window, and the interior of the observation window is fixedly connected with tempered glass.

[0013] This utility model has the following beneficial effects: 1. This utility model forms a closed space through a cooling chamber to reduce cold air leakage, and a cold air fan continuously outputs a strong cold source to cool the cooling components. In conjunction with the alternating fixed frames and centrally symmetrical ventilation pipe groups in the cooling components, the coverage of cold air is expanded, and the air outlets quickly expel hot air from the chamber. At the same time, the layered support plate increases the cooling capacity per batch. It shortens the cooling time of roasted fish from multiple dimensions such as cold source supply, cold retention, and space utilization, effectively improving processing efficiency. Moreover, the vertical pipes in the ventilation pipe group conduct cold air, the connecting pipes distribute the air evenly, and the horizontal pipes release cold air evenly through equidistant air outlets at the bottom, achieving "rapid cold air delivery + uniform release", further shortening the cooling time of a single batch of roasted fish and improving production efficiency.

[0014] 2. This utility model uses a controller to preset the cooling time and links a timer alarm to promptly issue an alarm to remind the material to be picked up after the cooling reaches the target, thus avoiding problems of over-cooling or under-cooling caused by misjudgment of the time by manual monitoring.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0024] Please see Figures 1 to 6This utility model relates to a rapid cooling and freshness-locking device for pre-prepared grilled fish, comprising a base frame 100; a cooling chamber 200 is fixedly connected to the top of the base frame 100, and the interior of the cooling chamber 200 is provided with a cooling component 400 for cooling the grilled fish, a support tray 500 for supporting the grilled fish, and an oil collection box 600 for receiving dripping oil from the grilled fish. A cold air fan 300 for providing cold air to the cooling component 400 is fixedly connected to the interior of the base frame 100. Multiple air outlets 202 are provided on both sides of the cooling chamber 200, and the cooling chamber 200 forms a closed space to reduce the leakage of cold air. Ensure that the cold energy is concentrated on the grilled fish; the air cooler 300 continuously outputs sufficient cold air to provide a strong cold source for the cooling component 400, directly accelerating the cooling speed; the support tray 500 supports the grilled fish in layers, increasing the cooling capacity of the device per batch and reducing batch waiting time; the oil collection box 600 collects oil to avoid contaminating the cooling component 400, prevents obstruction of cold energy delivery, and ensures cooling efficiency; the air outlet 202 quickly exhausts hot air from the chamber, maintaining a low-temperature environment and preventing hot air from lingering and prolonging the cooling time. By shortening the cooling time from multiple dimensions such as cold source supply, cold energy retention, and space utilization, the processing efficiency is improved. Multiple guide rails 203 and support frames 204 are fixedly connected to both sides of the inner wall of the cooling chamber 200. The support plate 500 is slidably connected to the inside of two corresponding guide rails 203. The oil collection box 600 is slidably connected between the corresponding guide rail 203 and the support frame 204. The guide rails 203 allow the support plate 500 to smoothly slide when picking up and putting down the grilled fish and the oil collection box 600 to be cleaned, reducing operation jamming time and shortening the gap between loading and unloading and cleaning. The support frame 204 stably supports the oil collection box 600 to prevent it from shifting and causing oil leakage. The cooling assembly 400 includes multiple fixed frames 401 fixedly connected inside the cooling chamber 200. The fixed frames 401, the support trays 500, and the oil collection boxes 600 are distributed alternately. Inside the fixed frames 401, there are two centrally symmetrically distributed ventilation pipe groups 402. The alternating distribution design allows the ventilation pipe groups 402 to precisely correspond to each layer of support trays 500. The cold air can directly act on each batch of grilled fish. With the centrally symmetrical ventilation pipe groups 402, the coverage of the cold air is expanded, local cooling dead zones are reduced, and the grilled fish is cooled down synchronously as a whole, which significantly shortens the cooling time. The ventilation duct assembly 402 includes multiple horizontal pipes 402a fixedly connected inside the fixed frame 401 and a connecting pipe 402c perpendicular to the horizontal pipes 402a. The connecting pipe 402c is connected to all the horizontal pipes 402a. Multiple equidistant air outlets 402b are installed at the bottom of the horizontal pipes 402a. A vertical pipe 402d connected to the output end of the air cooler 300 is provided outside the cooling chamber 200. The vertical pipe 402d is connected to the connecting pipe 402c. The vertical pipe 402d quickly conducts the cold air from the air cooler 300 to the connecting pipe 402c. The connecting pipe 402c evenly distributes the cold air to each horizontal pipe 402a, reducing the loss of cold air transmission. The equidistant air outlets 402b blow the cold air towards the grilled fish with a uniform density, avoiding slow local cooling that slows down the overall process. This achieves "rapid cold air delivery + uniform release", directly shortening the cooling time of a single batch of grilled fish and improving production efficiency.

[0025] Specifically, a cabinet door 201 is rotatably connected to the front of the cooling chamber 200, and a controller 700 for controlling the operation of the air cooler 300 is fixedly connected to the outside of the cabinet door 201. A timer alarm 800 is fixedly connected to the top of the cooling chamber 200, and the timer alarm 800 is electrically connected to the controller 700. The controller 700 presets the cooling time, and the timer alarm 800 promptly reminds the user to pick up the material after the time is reached, so as to avoid over-cooling or under-cooling due to misjudgment of the time by manual operation.

[0026] Furthermore, filters 601 corresponding to air outlets 202 are fixedly connected to both sides of the oil collection box 600; The top of the support plate 500 has a honeycomb mesh structure. Multiple rollers 501 are rotatably connected to both sides of the inner side of the support plate 500, and the rollers 501 roll inside the corresponding guide rails 203. The honeycomb mesh structure allows cold air to penetrate the support plate 500 and contact the bottom of the grilled fish, eliminating the bottom cooling dead zone and avoiding the overall cooling time being prolonged due to slow bottom cooling. The rollers 501 reduce the friction between the support plate 500 and the guide rails 203, making it easier and faster to pull out. The front of the oil receiving box 600 is rotatably connected to a second handle 602, and the front of the bearing plate 500 is rotatably connected to a first handle 502. The front of cabinet door 201 has an observation window, and the inside of the observation window is fixedly connected with tempered glass.

[0027] The operation process of this embodiment is as follows: When rapid cooling of the grilled fish is required, firstly, place the grilled fish to be cooled stably on top of the honeycomb mesh support tray 500. After placement, push the first handle 502 to make the support tray 500 slide back to its initial position in the cooling chamber 200 along the guide rail 203. Then, close the cabinet door 201. Subsequently, preset the cooling time through the controller 700 outside the cabinet door 201, and simultaneously press the start button on the controller 700 to start the air cooler 300. After the air cooler 300 starts running, the cold air is transmitted through its output end to the vertical pipe 402d outside the cooling chamber 200, and then through the vertical pipe... 402d is introduced into the connecting pipe 402c in each fixed frame 401. The connecting pipe 402c evenly distributes the cold air to the horizontal pipe 402a connected to it. Finally, through the air outlets 402b evenly distributed at the bottom of the horizontal pipe 402a, the air is blown onto the grilled fish on each layer of the support tray 500 with a uniform density. At the same time, the hot air in the cooling chamber 200 is quickly discharged through the air outlet 202. The oil collection box 600 collects the oil dripping from the grilled fish in real time. When the cooling time reaches the preset value of the controller 700, the timer alarm 800, which is electrically connected to the controller 700, sounds an alarm to remind the operator to remove the fish and complete the single rapid cooling operation of the grilled fish.
