Description

Technical Field

[0001] The present invention relates to the field of food freezing devices, and in particular to a container box and a device for quick-freezing food. Background Art

[0002] With the growth of people's economic capabilities and improvements in living standards, expectations for the quality and safety of fresh food have risen. To meet this demand and expand commercial sales, the food quick-freezing industry has developed rapidly. The food quick-freezing process involves rapidly cooling food at low temperatures (below -18°C) to below the active temperature of microorganisms. This limits microbial growth and certain biochemical reactions without the use of preservatives or additives, ensuring food safety. The rapid cooling method helps convert the moisture within the food into small, needle-shaped ice crystals (less than 100μm in diameter), which retains moisture while avoiding significant damage to the cell structure, maximizing the food's nutritional value and taste. One common quick-freezing process involves using low-temperature air to cool food. However, for delicate fruits and vegetables, the quick-freezing process can damage their surfaces, compromising their subsequent storage and transportation. Therefore, the packaging and stacking of fruits and vegetables during the quick-freezing process must be designed appropriately to meet the rapid cooling requirements. In addition, during subsequent frozen storage, quick-frozen foods should be kept away from direct contact with air to slow down oxidation and delay food spoilage.

[0003] In the currently common quick-freezing process, low-temperature air is forced to circulate directly with the food to be cooled, exchanging heat. Food is typically placed directly or in plastic packaging on metal trays for cooling. However, for fragile fruits, simply placing them flat on the trays can cause collisions and damage the food's surface. Furthermore, allowing quick-frozen food to come into contact with air is detrimental to its preservation and storage. Summary of the Invention

[0004] The embodiments of the present invention provide a container and device for quick-freezing food, which are used to solve the problems of the existing quick-freezing technology that the surface tissue of the food is easily damaged and the contact of the quick-frozen food with the air is not conducive to the preservation and storage of the food.

[0005] An embodiment of the present invention provides a container for quick-freezing food, comprising:

[0006] A box body is provided with a accommodating cavity formed inside the box body, an opening is provided at the top of the box body, and an angle between at least one pair of opposite side walls of the box body and the bottom wall of the box body is greater than 90°, forming inclined side walls that support the food.

[0007] According to an embodiment of the container box for quick-freezing food of the present invention, the material of the box body is ice.

[0008] According to an embodiment of the container for quick-freezing food according to the present invention, the opening is a rectangular opening, and any pair of opposite edges of the opening extend outward to form a supporting portion.

[0009] According to an embodiment of the present invention, a container box for quick-freezing food has four side walls, wherein an angle between a pair of opposite side walls and the bottom wall of the box body is greater than 90°, and another pair of opposite side walls is perpendicular to the bottom wall of the box body.

[0010] According to an embodiment of the present invention, the container box for quick-freezing food further comprises a box body top cover, wherein the box body top cover covers the opening.

[0011] According to an embodiment of the present invention, a storage box for quick-freezing food has a sheet-like structure. When the box top cover is closed on the opening, the lower surface of the box top cover contacts the edge of the opening. The box top cover and the edge of the opening can be adhered to each other by adding water during freezing, so that the box body and the box top cover form a sealed box body.

[0012] According to an embodiment of the container box for quick-freezing food of the present invention, the material of the box top cover is also ice.

[0013] According to an embodiment of the container box for quick-freezing food of the present invention, a plurality of ventilation holes are provided on the side wall of the box body.

[0014] According to an embodiment of the container box for quick-freezing food of the present invention, a plurality of downwardly recessed recesses are provided at intervals on the upper surface of the bottom wall of the box body.

[0015] An embodiment of the present invention further provides a container device for quick-freezing food, comprising a plurality of container boxes for quick-freezing food as described above, wherein the box bodies of the container boxes are arranged at equal intervals, and two adjacent box bodies are connected.

[0016] The container for quick-freezing food provided in an embodiment of the present invention contains frozen food in a container. During the quick-freezing process, the structural integrity of the food inside is protected, surface damage and contamination caused by collisions are avoided, and processing losses are reduced. Because the angle between the opposing side walls of the container body and the bottom wall is greater than 90°, inclined side walls are formed to support the food. The two inclined side walls and the bottom wall form a trough-shaped structure that supports the food, preventing the bottom of fragile food from making large-area contact with the container, and minimizing surface damage caused by adhesion or collisions.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] The following combination Figures 1 to 2 The present invention describes a container and a device for quick freezing of food according to an embodiment of the present invention.

[0024] Figure 1 A schematic diagram of a container box for quick freezing of food is shown as follows: Figure 1As shown, the container box for quick-freezing food includes: a box body 11. The material of the box body 11 is ice. Ice is made by freezing water under low temperature conditions. No chemicals are added to it. It is a healthy, environmentally friendly, non-toxic, harmless, and recyclable material. It is also relatively cheap and will not increase the freezing cost. A container cavity is formed inside the box body 11. The container cavity is used to place frozen food. The top of the box body 11 is provided with an opening. The opening is a rectangular opening. The frozen food can be placed in the container cavity through the opening. Any pair of opposite edges of the opening extends outward to form a support portion 2. The upper surface of the support portion 2 is a horizontal surface. The support portion 2 can be used to fit with the box body top cover 1 and to support the upper container box when the container boxes are stacked. By using a container box to hold frozen food, the structural integrity of the internal food can be protected during the quick-freezing process, surface damage and contamination caused by mutual collision or squeezing can be avoided, and processing losses can be reduced. The box body 11 includes four side walls 3, wherein the angle between a pair of opposing side walls 3 and the bottom wall 4 of the box body 11 is greater than 90°, and the angle between another pair of opposing side walls 3 and the bottom wall 4 of the box body 11 is perpendicular to the bottom wall 4 of the box body 11. Because the angle between the opposing pair of side walls 3 of the box body 11 and the bottom wall 4 of the box body 11 is greater than 90°, inclined side walls are formed to support the food. The two inclined side walls and the bottom wall 4 form a trough structure that supports the food, preventing the bottom of the fragile food from coming into contact with a large area of ​​the container, and reducing surface damage caused by adhesion or collision. At the same time, the tilt of the side walls 3 also increases the heat exchange area of ​​the container, allowing cold air to directly pass through the side walls 3 to exchange heat with the food, maintaining a certain heat exchange rate during the quick-freezing process, and ensuring that the food is quickly cooled to below -18°C.

[0025] It should be noted that in this embodiment, the box body 11 includes four side walls 3, but the number of side walls 3 is not limited to four. It can also include only one inverted conical side wall, or it can include six or more side walls 3. In this embodiment, the angle between a pair of opposing side walls 3 and the bottom wall 4 of the box body 11 is greater than 90°, and the other pair of opposing side walls 3 is perpendicular to the bottom wall 4 of the box body 11. Of course, the angle between the two pairs of opposing side walls 3 and the bottom wall 4 of the box body 11 can also be greater than 90°. In this way, the side walls 3 can better support the food, further preventing the bottom of fragile food from contacting a large area with the container, and reducing surface damage caused by adhesion or collision. The size of the box body 11 and the inclination angle of the side walls 3 of the box body 11 can be determined according to the specific type and quantity of food.

[0026] According to an embodiment of the present invention, the storage box for quick-freezing food in this embodiment also includes: a box top cover 1, which covers the opening. The material of the box top cover 1 is also ice. The provision of the box top cover 1 can not only reduce the contact between the food in the box body 11 and the outside air, but also protect the food from being squeezed and collided from the top.

[0027] Furthermore, the box body cover 1 is a sheet-like structure. When the box body cover 1 is closed on the opening, the lower surface of the box body cover 1 contacts the edge of the opening. The box body cover 1 and the edge of the opening can be adhered to each other by adding water during freezing, so that the box body 11 and the box body cover 1 form a sealed box body. At this time, since the interior of the box body 11 is filled with nitrogen during the quick freezing process, the box body 11 and the box body cover 1 can be sealed to prevent the food from directly contacting the air, weakening the respiration of the food cells, delaying the spoilage of the food, and extending the shelf life. At the same time, after the box body cover 1 is set, it is also convenient to stack the box body 11 in multiple layers. The use of a multi-layer stacking method can also improve space utilization in subsequent frozen storage while ensuring the integrity of the food structure.

[0028] It should be noted that in this embodiment, the food is randomly stacked in the box body 11. Alternatively, the food can be manually placed at equal intervals. This ensures that the distance between the food is guaranteed, which is more conducive to heat exchange between the food and the cold air (usually nitrogen), thereby improving the freezing efficiency. Of course, the food placement method is not limited to this. Those skilled in the art can determine it according to the quantity and type of food during specific implementation.

[0029] According to an embodiment of the present invention, the sidewall 3 of the box body 11 is provided with multiple ventilation holes. These ventilation holes further improve the heat exchange efficiency between the food and the cold air, allowing the food in the box body 11 to quickly cool to below -18°C, shortening the cooling time. After freezing, water can be dripped into the ventilation holes. The water quickly freezes at low temperatures, sealing the ventilation holes and achieving a sealing effect. In this embodiment, the upper surface of the bottom wall 4 of the box body 11 is provided with multiple downwardly concave recesses at intervals. For some small and fragile foods, the food at the bottom is squeezed by the food above, which can easily damage the surface of the food at the bottom. Therefore, the recesses are provided on the upper surface of the bottom wall 4. After the food is placed in the box body 11, the food at the bottom is located within the recesses. At this time, the contact surface between the food at the bottom and the recesses is a curved surface. Compared to direct contact with a flat surface, the food has a larger contact surface when in contact with the curved surface. Therefore, the food at the bottom is less likely to be damaged, further maintaining the integrity of the food structure.

[0030] According to an embodiment of the present invention, a plurality of support plates are further placed in the box body 11 in this embodiment. When in use, the food and the support plates are placed in sequence, that is, the first layer of food is placed first, and then the first layer of support plates is placed above the first layer of food, and then the second layer of food is placed on the first layer of support plates, and then the second layer of support plates is placed above the second layer of food, and so on and so forth until the box body 11 is full. The advantage of providing support plates is that it ensures that each food on the same layer is subjected to uniform force and will not be damaged due to excessive force on a certain food. Of course, the support plates of two adjacent layers can also be connected by support rods, so that only the support plates are subjected to force, and the food on each layer is not subjected to the pressure of the upper layer of food. This further avoids surface damage and contamination caused by collision and extrusion of foods, and maintains the integrity of the food structure.

[0031] Figure 2 A schematic diagram of a structure of a container for quick freezing of food is shown as follows: Figure 2 As shown, an embodiment of the present invention further provides a container device for quick-freezing food, comprising a plurality of container boxes for quick-freezing food as described above, wherein the box bodies 11 of the container boxes are arranged at equal intervals. In this embodiment, the support portions 2 of two adjacent box bodies 11 are connected, and the support portions 2 of the two box bodies 11 are integrally formed, thereby realizing the connection between the two adjacent box bodies 11, and forming a ventilation channel 12 between the two adjacent box bodies 11. When the container boxes are stacked in multiple layers, the ventilation channel 12 between the two adjacent container boxes on the same layer can provide a circulation channel for cold air, further enhancing the heat exchange efficiency between the food and the cold air, so that the food in the box body 11 is quickly cooled to below -18°C, thereby shortening the cooling time.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
