Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation equipment, in particular to a constant temperature device for enzyme storage. Background Art

[0002] The production and application of enzymes has a history of more than 80 years at home and abroad. In the 1980s, bioengineering as an emerging high-tech has developed rapidly in my country, and the manufacturing and application fields of enzymes have gradually expanded. Now the enzyme treatment process has been recognized as a green production process that meets environmental protection requirements. It not only improves and enhances the wearing performance of textiles, but also is beneficial to the protection of ecological environment because of its non-toxicity, small dosage, biodegradable wastewater, and no pollution.

[0003] If the temperature of enzyme preparations is not constant during storage, the activity of enzyme preparations is easily affected, causing the quality of the product to change due to the attenuation of enzyme activity, thereby reducing the quality of production. In order to ensure the activity of enzyme products, most companies use special warehouses for enzyme storage to keep the temperature of enzyme preparations below 10°C. However, during the transportation of enzyme products, enzyme products are easily affected by the ambient temperature and their activity is attenuated.

[0004] Therefore, in the case of a heat-insulating enzyme raw material packaging box proposed in the patent with publication number CN220363800U, the heat-insulating block can insulate the bottle storing the enzyme in the placement chamber to prevent the temperature in the placement chamber from being too high, thereby placing the placement chamber in a low-temperature environment, reducing bacterial growth, and preventing enzyme denaturation and inactivation. However, the heat-insulating device requires high sealing performance, and the heat-insulating effect is effective. When the ambient temperature differs greatly from the heat-insulating temperature, the heat-insulating effect is correspondingly poor, which is easy to affect the enzyme activity.

[0005] There is also a modified enzyme storage device with a heat preservation effect proposed in the patent with publication number CN215286324U. By setting an electric heater, a heat-conducting layer and a heat storage layer, the heat output by the electric heater is transmitted to the heat storage layer via the heat-conducting layer, and the heat is accumulated by the heat storage layer and slowly diffused to the storage area located in the center of the insulation box to form a circulation, so that the modified enzyme sample placed on the plate can obtain a continuous supply of heat supplement, achieving the effect of heat preservation. On the basis of heat preservation and heat insulation, the device adds a heating component to ensure the heat preservation effect, and can heat and keep warm the enzyme with heating and heat insulation requirements. However, the above device or heat preservation and heat insulation effect is easily affected by the sealing of the device, the influence of the ambient temperature difference or the complicated heating and constant temperature components attached, which is relatively complicated and not suitable for industrial production and transportation. Utility Model Content

[0006] The utility model aims to provide a thermostatic device for enzyme storage, so as to solve the technical problems that the existing thermostatic storage devices for enzymes have poor effects or complicated attached heating thermostatic components.

[0007] The embodiments of the present invention are implemented by the following technical solutions:

[0008] A constant temperature device for enzyme storage comprises a shell, a container for containing enzymes arranged on the shell and a heat-insulating layer for heat preservation and heat insulation, and a phase-change heat-absorbing layer for absorbing and releasing latent heat is also arranged between the container and the heat-insulating layer.

[0009] Preferably, it further comprises a base detachably connected to the bottom surface of the shell, the base is connected to the phase change heat absorption layer, and the shell is provided with a mounting layer for mounting the phase change heat absorption layer.

[0010] Preferably, the shell is provided with an internal thread, the base is provided with an external thread for connecting the internal thread, and the mounting layer and the phase change heat absorption layer are configured to be cylindrical.

[0011] Preferably, the base is also provided with a handle for holding.

[0012] Preferably, the container further comprises a cover for sealing the container and a handle for opening the cover.

[0013] Preferably, the cover body is further provided with an inner sealing ring and an outer sealing ring for sealing the container.

[0014] Preferably, the shell is also provided with a connecting frame for connecting the container and limiting the phase change heat absorption layer.

[0015] By adopting the technical solution, while the heat-insulating layer insulates the container to prevent the container from exchanging heat with the external environment, the phase-change heat-absorbing layer arranged in the shell installation layer can also absorb and release latent heat. When stored in a low-temperature warehouse, the phase-change material layer releases latent heat. When the device and the enzyme therein are taken out for transportation, the phase-change material layer after releasing the latent heat can absorb environmental heat to prevent heat from entering the container and affecting the activity of the enzyme. Similarly, for enzymes that need to be heated for storage, the phase-change material layer absorbs latent heat when stored in the warehouse, and releases latent heat to the environment when transported to the outside world, to ensure that the container does not exchange heat with the environment as much as possible.

[0016] It also avoids using additional heating or cooling devices to increase the burden on the device. Instead, the phase change material is filled in the phase change material layer to repeatedly absorb and release latent heat, making full use of the heat in the environment to store the enzyme at a constant temperature and saving energy.

[0017] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0018] 1. The utility model can ensure that the enzyme product in the container does not exchange heat with the environment as much as possible through the phase change heat absorption layer, further enhancing the constant temperature effect;

[0019] 2. The utility model does not use additional heating or cooling devices, and the phase change material is reused, saving costs and energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example 1

[0034] A constant temperature device for enzyme storage comprises a shell 1, a container 5 for containing enzymes arranged on the shell 1 and a heat-insulating layer 4 for heat preservation and heat insulation, and a phase-change heat-absorbing layer 3 for absorbing and releasing latent heat is also arranged between the container 5 and the heat-insulating layer 4.

[0035] In this embodiment, a base 2 is further included which is detachably connected to the bottom surface of the shell 1 , the base 2 is connected to the phase change heat absorption layer 3 , and the shell 1 is provided with a mounting layer 12 for mounting the phase change heat absorption layer 3 .

[0036] In this embodiment, the housing 1 is provided with an internal thread 11 , the base 2 is provided with an external thread 21 for connecting the internal thread 11 , and the mounting layer 12 and the phase change heat absorption layer 3 are configured to be cylindrical.

[0037] In this embodiment, a cover 6 for sealing the container 5 and a handle 7 for opening the cover 6 are also included.

[0038] In this embodiment, the housing 1 is further provided with a connecting frame 13 for connecting the container 5 and limiting the position of the phase change heat absorption layer 3 .

[0039] Working principle and usage:

[0040] After the enzyme is stored in the container 5, while the insulation layer 4 insulates the container 5 to prevent the container 5 from exchanging heat with the external environment, the phase change heat absorption layer 3 arranged in the mounting layer 12 of the shell 1 can also absorb and release latent heat.

When the device and the enzyme therein are taken out for transportation, the phase change material layer after releasing the latent heat can absorb environmental heat to prevent heat from entering the container 5 and affecting the activity of the enzyme. Similarly, for enzymes that need to be heated for storage, the phase change material layer absorbs latent heat when stored in the warehouse, and releases latent heat to the environment when transported to the outside world, to ensure that the container 5 does not exchange heat with the environment as much as possible.
