Description

Technical Field

[0001] This utility model relates to the field of cold chain distribution technology, specifically to a multi-temperature zone cold chain distribution turnover box for goose products. Background Technology

[0002] In the current distribution of goose products, transportation still primarily relies on traditional non-temperature-controlled crates. These crates are designed mainly for basic load-bearing and ventilation, using plastic baskets or bamboo containers as transport carriers for live geese, with simple bedding such as straw or wood chips for cushioning to reduce physical damage during transport. However, with the extension of the goose product processing industry chain and the increasing demand for freshness from consumers, traditional transportation methods are no longer sufficient to meet the quality assurance requirements of temperature-sensitive products such as goose meat products and chilled goose by-products. Cold chain distribution technology is gradually becoming an industry necessity.

[0003] While existing cold chain turnover boxes achieve basic low-temperature preservation by adding ice packs or simple insulation layers, their core design still has significant flaws. On the one hand, traditional turnover boxes generally lack multi-temperature zone division capabilities, making it impossible to manage the differentiated temperature control needs of different links in the goose product processing chain, such as live animal transportation, cutting and processing, and cooked food delivery. This leads to accelerated quality deterioration of high-value-added products and ordinary raw materials due to cross-contamination caused by temperature. On the other hand, the insulation structure of existing turnover boxes is crudely designed, with insufficient sealing at the box seams. External heat continuously penetrates into the box through conduction, convection, and radiation, and there is a lack of effective thermal insulation between different temperature zones inside the box. For example, the temperature gradient between the freezing and refrigeration zones is disordered due to the convection of hot and cold air, which not only increases energy consumption but also significantly reduces the cold release efficiency of phase change materials, making it difficult to maintain a constant low-temperature environment. As a result, traditional cold chain turnover boxes cannot achieve stable temperature control throughout the goose product circulation process, becoming a technical bottleneck restricting the high-quality development of the industry. Utility Model Content

[0004] To address the problems mentioned in the background section, a multi-temperature zone cold chain distribution and turnover box for goose products is proposed. The technical solution adopted by this utility model is as follows:

[0005] A multi-temperature zone cold chain distribution turnover box for goose products includes a box body with anti-drop cushioning function. A fresh-keeping section is fixedly installed inside the hollow interior of the box body. The hollow interior of the fresh-keeping section is divided into several temperature-controlled zones based on several heat-insulating partitions. A vacuum layer for isolating heat conduction is provided between the inner wall of the box body and the fresh-keeping section. A box lid for sealing protection is hinged to one side of the top of the box body.

[0006] Preferably, a plurality of heat-insulating partitions of equal height are fixedly installed inside the preservation section, and a plurality of temperature-controlled zones are formed between the heat-insulating partitions and the preservation section. Each heat-insulating partition can be detachably installed with a phase change layer on both sides near the temperature-controlled zone to maintain the dynamic thermal balance of the temperature-controlled zone.

[0007] Preferably, a plurality of support columns are equidistantly installed at the bottom of the preservation section. The support columns are fixedly installed at the bottom of the hollow interior of the box. The gap between the preservation section and the box and the gap between the plurality of support columns together form the vacuum layer.

[0008] Preferably, a vacuum valve communicating with the vacuum layer is fixedly installed on one side of the housing.

[0009] Preferably, the side of the box cover near the box body is provided with a sealing element that matches the vacuum layer, and the inner ring of the sealing element is provided with a sealing partition that matches the heat insulation partition.

[0010] Preferably, a hinge is provided on one side of the top of the box, and the box cover is installed on the top of the box based on the hinge.

[0011] Preferably, the bottom of the housing is equipped with a cushioning and shock-absorbing base.

[0012] The beneficial effects of this utility model's multi-temperature zone cold chain distribution and turnover box for goose products are as follows:

[0013] 1. The fresh-keeping section is divided into multiple independent temperature-controlled zones using insulated partitions. Each zone can be managed according to the differentiated temperature control needs of different stages in the goose product processing chain. The insulated partitions are made of high heat-resistant materials, effectively blocking the convection of hot and cold air and preventing airflow circulation between the freezing and refrigeration zones due to temperature differences, thereby eliminating temperature gradient disturbances. The interior of the box is designed with a vacuum layer to isolate external heat conduction. Combined with the hinged seals on the box lid and the double airtight barrier of the sealed partitions, it completely blocks the intrusion of external heat into the box through conduction, convection, and radiation. This solves the problem of temperature cross-contamination caused by the lack of zone management in traditional turnover boxes, while also suppressing the leakage of cold air through the box seams or thermal bridge effect of the partitions, ensuring that the temperature of each temperature-controlled zone remains stable within the preset range.

[0014] 2. By configuring removable PCM material phase change layers on both sides of the insulation partition, the solid-liquid phase change characteristics are utilized to dynamically regulate temperature fluctuations in the temperature control zone. This is mainly achieved by the PCM absorbing heat to slow the temperature rise inside the chamber and releasing heat to prevent excessively low internal temperatures, thus keeping the temperature fluctuation range within a reasonable range. Combined with the synergistic effect of the vacuum layer and sealing system, the cold energy release efficiency of the PCM is significantly improved, solving the problems of high energy consumption and short insulation time caused by the low cold energy density and uncontrollable release of traditional ice packs.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] like Figure 1-2 As shown, a multi-temperature zone cold chain distribution turnover box for goose products includes a box body 1 with anti-drop cushioning function. A fresh-keeping section 2 is fixedly installed inside the hollow interior of the box body 1. The hollow interior of the fresh-keeping section 2 is divided into several temperature-controlled zones based on several heat-insulating partitions 201. A vacuum layer 3 for isolating heat conduction is provided between the inner wall of the box body 1 and the fresh-keeping section 2. A box cover 4 for sealing protection is hinged to one side of the top of the box body 1.

[0020] In this embodiment, a preservation section 2, which is divided into several temperature-controlled zones by several heat-insulating partitions 201, is fixedly installed inside the hollow interior of the box 1. A vacuum layer 3 is provided between the inner wall of the box 1 and the preservation section 2. A box cover 4 is hinged to the top of the box 1. The preservation section 2 is divided into several temperature-controlled zones based on the heat-insulating partitions 201, so that goose products with different required storage temperatures can be stored in different temperature-controlled zones. The box cover 4 hinged to the top of the box 1 seals the preservation section 2, ensuring that there is no temperature interference between the temperature-controlled zones in the preservation section 2. The vacuum layer 3 isolates the preservation section 2 from the external environment, ensuring that the temperature of each temperature-controlled zone in the preservation section 2 does not leak out, thereby ensuring that a constant low-temperature environment can be maintained in the temperature-controlled zone to better preserve the goose products.

[0021] In one embodiment, a plurality of heat-insulating partitions 201 of equal height are fixedly installed inside the preservation section 2. A plurality of temperature control zones are formed between the heat-insulating partitions 201 and the preservation section 2. A phase change layer 202 for maintaining the dynamic thermal balance of the temperature control zone can be detachably installed on both sides of each heat-insulating partition 201 near the temperature control zone.

[0022] In this embodiment, the heat insulation partition 201 inside the preservation section 2 is made of heat insulation material, and the heat insulation partition 201 is tightly connected to the inner wall of the preservation section 2 and the lid 4 to ensure that the cold energy in the temperature control zone will not overflow. Furthermore, by detachably installing a phase change layer 202 made of PCM material on the heat insulation partition 201, the low temperature environment in a single temperature control zone is kept constant by the PCM material in the phase change layer 202.

[0023] In one embodiment, a plurality of support columns 203 are equidistantly installed at the bottom of the preservation section 2. The support columns 203 are fixedly installed at the bottom of the hollow interior of the box body 1. The gap between the preservation section 2 and the box body 1 and the gap between the plurality of support columns 203 together form the vacuum layer 3.

[0024] In this embodiment, the support column 203 fixes the preservation part 2 inside the box 1, and the gap between the support columns 203 connects to the vacuum layer 3 on the outer periphery of the preservation part 2. The support column 203 is made of heat-insulating metal material. By wrapping the preservation part 2 in a vacuum environment, the constant low temperature environment inside the preservation part 2 is ensured to remain unchanged due to heat conduction.

[0025] In one embodiment, a vacuum valve 102 communicating with the vacuum layer 3 is fixedly installed on one side of the housing 1.

[0026] In this embodiment, an external vacuum pump draws air from the vacuum layer 3 to the outside through an air valve, thereby achieving a vacuum effect in the vacuum layer 3; if necessary, outside air is injected back into the vacuum layer 3 through the vacuum layer 3 to prevent the lid 4 from being unable to open due to the pressure difference between the outside atmospheric pressure and the vacuum layer 3.

[0027] In one embodiment, the box cover 4 is provided with a sealing element 401 matching the vacuum layer 3 on the side near the box body 1, and the inner ring of the sealing element 401 is provided with a sealing partition 402 matching the heat insulation partition 201.

[0028] In this embodiment, the sealing element 401 is made of elastic material. When the lid 4 abuts against the body 1, the sealing element 401 seals the vacuum layer 3. The sealing partition 402 provided on the inner side of the sealing element 401 abuts against the heat insulation partition 201, thereby sealing the temperature control area of ​​the preservation section 2.

[0029] In one embodiment, a hinge 103 is provided on one side of the top of the box 1, and the box cover 4 is mounted on the top of the box 1 based on the hinge 103.

[0030] In this embodiment, the lid 4 is hinged to the top of the box body 1 by the hinge 103, which facilitates the opening and closing of the lid 4.

[0031] In one embodiment, a cushioning and shock-absorbing base 101 is installed at the bottom of the housing 1.

[0032] In this embodiment, the buffer protection base 101 covers the bottom of the box 1 to prevent the box 1 from being damaged due to accidental drops.

[0033] The specific operating principle of this utility model's multi-temperature zone cold chain distribution turnover box for goose products is as follows:

[0034] First, open the box cover 4 and fix the pre-treated phase change layer 202 on the corresponding heat insulation partition 201. After placing the goose products in the corresponding temperature control zones, close the box cover 4 and start the external vacuum pump. Based on the vacuum valve 102, the air in the vacuum layer 3 inside the box 1 is extracted. At this time, due to the pressure difference between the vacuum layer 3 and the outside atmospheric pressure, the box cover 4 will tightly cover the top of the box 1. After the vacuum operation is completed, the PCM material of the phase change layer 202 will undergo a phase change and absorb heat, reducing the temperature in the temperature control zone to the target temperature range and maintaining it in that range. Then, transportation can be carried out. When the goose products need to be taken out after transportation, the vacuum layer 3 is connected to the outside environment through the vacuum valve 102, so that air is introduced into the vacuum layer 3 until the internal and external pressures are consistent. Then the box cover 4 can be opened to take out the goose products.

[0035] The present invention and its embodiments have been described above. This description is not restrictive. The accompanying drawings are only one embodiment of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
