Description

Technical Field

[0001] This utility model relates to the field of tray racks for frozen goods, specifically to a frozen goods tray for a tunnel-type quick-freezing machine. Background Technology

[0002] After the fish undergoes initial processing such as slaughtering, it needs to be quick-frozen to preserve its quality, maintain its taste, and extend its shelf life. Currently, for high-end fish such as small sturgeon, the fish are usually placed on frozen food trays and then sent into a tunnel-type quick-freezing machine for freezing.

[0003] However, existing technologies lack frozen food trays specifically designed for the shape and freezing characteristics of fish. When using general-purpose frozen food trays, it is difficult to secure the fish. Because the surface of fish is smooth, and they may shift due to vibration or airflow during quick-freezing, the fish may stack on top of each other, affecting the uniformity and efficiency of freezing. In addition, fish will seep out some body fluid in the early stage of freezing, and the body fluid will quickly freeze into ice at low temperature, which will easily stick the fish to the surface of the tray. When separating the fish after freezing, external force is often required, which can easily cause damage to the fish skin or the fish meat, affecting the appearance and commercial value of the product, and also increasing the difficulty of operation and losses. Utility Model Content

[0004] The purpose of this utility model is to provide a frozen food tray for a tunnel-type quick-freezing machine. This tray utilizes several independent, upward-opening cavities within its body. The side walls of these cavities extend in a concave arc shape to conform to the fish's contour. Through holes are also provided in the tray to connect the cavities. This solution addresses the technical problems in existing frozen food trays, such as difficulty in effectively securing fish, leading to fish displacement and stacking during quick-freezing, affecting freezing uniformity, and the tendency for liquid accumulation in the fish to adhere to the tray, causing difficulty in separation after freezing and potential damage to the fish. The solution provides benefits including effective fish securing, prevention of displacement and stacking, promotion of cold air circulation, reduction of fish adhesion, ease of separation after freezing, improved freezing efficiency, and enhanced product quality.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A frozen food tray for a tunnel-type quick-freezing machine includes a tray body, wherein the tray body is provided with a plurality of independent receiving cavities that open upwards.

[0007] The sidewalls on both sides of the extending direction of the receiving cavity are concave arc surfaces to fit the outline of the fish body;

[0008] The disc body has several through holes that connect to the receiving cavity.

[0009] Preferably, the bottom of the disc is provided with a plurality of drainage holes, each of which is connected to the bottom of the corresponding receiving cavity, for draining the accumulated liquid at the bottom of the receiving cavity.

[0010] Preferably, the bottom of the receiving cavity is provided with a water collection tank.

[0011] Preferably, the water collection trough extends along the extension direction of the receiving cavity in which it is located, and the cross-section of the water collection trough is V-shaped.

[0012] Preferably, the bottom of the disc is provided with a plurality of drainage holes, each of which is connected to a corresponding water collection tank for draining the liquid in the water collection tank.

[0013] Preferably, the bottom of the disc body is provided with several feet.

[0014] Preferably, a cold medium flow channel is formed between several of the legs.

[0015] Preferably, the concave arc surface is provided with anti-slip texture.

[0016] Preferably, a guide groove is provided on the concave arc surface, the guide groove extends along the extension direction of the receiving cavity and communicates with the through hole.

[0017] Preferably, the through hole extends through the disk body.

[0018] The beneficial effects of this utility model are:

[0019] Effectively positioning and fixing the fish, preventing displacement and stacking, and improving freezing uniformity: By setting up several independent receiving cavities, the positioning and movement of the fish are achieved; the side walls on both sides of the receiving cavity are designed with concave arc surfaces that conform to the contour of the fish, thus enveloping and limiting the fish; this structural feature makes it difficult for the fish to roll or shift due to vibration or airflow after placement, effectively avoiding mutual contact and stacking between fish, ensuring that the fish are stably isolated, thereby ensuring that the cold air can evenly envelop the fish, improving the overall freezing uniformity and consistency.

[0020] Significantly improves cold air circulation efficiency and accelerates freezing speed: Multiple through holes are opened on the tray to connect the receiving cavity. This structural feature allows high-speed flowing low-temperature cold medium to enter the receiving cavity from the outside of the tray through the through holes and directly act on the surface of the fish. This breaks the situation of insufficient cold air circulation caused by the closed bottom or poor air permeability of traditional trays, and forms a three-dimensional and efficient cold medium channel, which greatly increases the contact area and heat exchange efficiency between the fish and the cold medium, thus directly bringing about the beneficial effects of faster freezing speed and improved quick-freezing efficiency.

[0021] Active drainage and expulsion of accumulated liquid can solve the problem of fish sticking together to a certain extent: by setting up drainage holes and water collection tanks, the liquid on the fish body will collect along the concave arc surface under the action of gravity to the water collection tank at the bottom, and can be discharged out of the container cavity in time through drainage holes; thus preventing liquid from accumulating and freezing in the contact area between the fish body and the plate; after freezing, the fish body is easy to separate completely, greatly reducing the risk of fish skin damage and fish meat damage, directly improving the product integrity rate and commercial value.

[0022] Optimize the airflow organization in the bottom space to achieve all-round rapid freezing: The bottom of the tray is equipped with support legs, and a cold medium flow channel is formed between the support legs. This structural feature allows low-temperature cold air to flow smoothly from the bottom of the tray, cooling the bottom of the containment cavity and the lower surface of the fish. This further shortens the freezing time, improves the overall energy efficiency of the equipment, and facilitates the drainage of liquid through the drain hole.

[0023] Enhance the stability of the fish and reduce adhesion between the fish and the plate: Anti-slip texture is set on the concave arc surface. By increasing the friction coefficient of the contact surface, the structural feature provides additional anti-slip resistance for the smooth fish in the initial stage of freezing, and reduces the contact area between the plate and the fish surface, thus reducing adhesion between the fish and the plate.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the relevant application and are not intended to limit the application. The described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0029] Example 1

[0030] See Figure 1 and Figure 2 This embodiment describes the basic technical solution that can achieve the purpose of this utility model: a frozen food tray for a tunnel-type quick-freezing machine. The basic technical solution aims to solve the problems of existing general trays being difficult to fix fish, uneven freezing, and fish easily sticking to the tray.

[0031] The frozen food tray of the tunnel-type quick-freezing machine in this embodiment includes a tray body 1, which is usually made of food-grade metal material with good thermal conductivity. The tray body 1 is divided by several partition walls to form several independent, upward-opening receiving cavities 2. The upward opening of the receiving cavity 2 should be able to allow fish to pass through. One or more fish can be placed in an independent receiving cavity 2, but it is preferred to place one fish to achieve physical isolation and prevent the fish from stacking on a large scale due to vibration or airflow during the quick-freezing process.

[0032] The side walls located on both sides of the extending direction of the receiving cavity 2, also known as the side walls on both sides of the extending direction when the fish is placed, are concave arc surfaces 3. The curvature of the concave arc surfaces 3 is designed to roughly match the outline of the fish, so as to position fish of different sizes, thereby forming a wrapping and limiting effect on the fish, effectively preventing the fish from rolling or shifting in the receiving cavity 2, ensuring the positional stability of the fish during the freezing process, and laying the foundation for uniform freezing.

[0033] To improve freezing efficiency, several through holes 4 are provided on the plate 1. Specifically, the through holes 4 can penetrate the plate 1 to form a cold medium circulation channel. When the quick-freezing machine is working, the high-speed flowing low-temperature cold air or other cold medium can directly enter the containment cavity 2 through these through holes 4, surround and impact the surface of the fish.

[0034] In summary, this embodiment achieves effective positioning and fixation of the fish by providing an independent receiving cavity 2 with a concave arc surface 3; and greatly promotes cold air circulation by providing through holes 4. The combination of these two features solves the technical problems mentioned in the background art, such as easy displacement and stacking of fish and uneven freezing.

[0035] Example 2

[0036] Based on Example 1, this example further provides an improved solution to the problem that fish may leak body fluid in the early stage of freezing, causing the fish to stick to the tray.

[0037] To prevent body fluid from accumulating and freezing at the bottom of the receiving cavity 2, this embodiment has several drainage holes 5 at the bottom of the tray body 1. Each drainage hole 5 is connected to the bottom of the corresponding receiving cavity 2 to drain the accumulated liquid at the bottom of the receiving cavity 2. When the body fluid or condensate seeping out of the fish accumulates at the bottom of the receiving cavity 2, it can be discharged to the outside of the tray in time under the action of gravity through the drainage holes 5, thereby avoiding the liquid from freezing into ice in the contact area between the fish and the tray. This makes it easier to separate the frozen fish intact and reduces the risk of fish skin breakage or fish meat damage during separation.

[0038] Alternatively, a water collection trough 6 can be installed at the bottom of the receiving cavity 2. The liquid in the receiving cavity 2 accumulates in the water collection trough 6, achieving centralized collection and preventing the liquid from overflowing over a large area at the bottom of the receiving cavity 2. Specifically, the water collection trough 6 extends along the extension direction of the receiving cavity 2. The cross-section of the water collection trough 6 is V-shaped. The V-shaped cross-section has a guiding and converging effect, which allows the liquid to converge more smoothly to the lowest point of the trough. At the same time, this shape also reduces the contact area between the liquid and the lower surface of the fish.

[0039] Alternatively, based on the water collection tank 6 at the bottom of the receiving cavity 2, several drainage holes 5 can be provided at the bottom of the plate body 1. Each drainage hole 5 is connected to the corresponding water collection tank 6 to drain the accumulated liquid in the water collection tank 6. In this way, the accumulated liquid collected in the water collection tank 6 can be drained efficiently and thoroughly through the drainage holes 5, and the anti-adhesion effect is better.

[0040] To better achieve the inventive objective of this application, the following common improvements can be made to the above-described embodiments 1 and 2:

[0041] The bottom of the tray 1 is provided with several support legs 7; the support legs 7 lift the entire tray 1, so that a gap is formed between it and the surface of the conveyor belt or support of the quick-freezing machine; this gap and the space between the support legs 7 together form a cold medium flow channel; this allows low-temperature cold air to flow smoothly from the bottom of the tray, directly and fully cooling the bottom surface of the receiving cavity 2 and the lower surface of the fish, realizing rapid freezing of the fish in all directions, further shortening the overall freezing time, and facilitating the drainage of accumulated liquid through the drain hole 5.

[0042] The concave arc surface 3 is provided with anti-slip texture; the anti-slip texture can be formed by stamping, etching and other methods. On the one hand, in the initial stage of freezing, the texture increases the coefficient of friction with the smooth fish surface, provides additional anti-slip resistance, and enhances the initial stability of the fish. On the other hand, the texture structure actually reduces the actual contact area between the fish and the concave arc surface 3 of the plate, preventing the fish and the plate from sticking to each other.

[0043] A flow guide groove 8 is provided on the concave arc surface 3. The flow guide groove 8 extends along the extension direction of the receiving cavity 2 and communicates with the through hole 4, thereby facilitating the flow of the cold medium on the surface of the fish.

"And" and "or" in this article are merely a description of the relationship between related objects, indicating that there can be three relationships.

[0045] It should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings; unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
