Description

Technical Field

[0001] This utility model relates to the field of liquid enzyme preparation preservation technology, and more specifically, to a liquid enzyme preparation preservation device. Background Technology

[0002] Enzyme preparations are biological products containing purified and processed enzymes that possess catalytic functions. They are mainly used to catalyze various chemical reactions in production processes, characterized by high catalytic efficiency, high specificity, mild reaction conditions, reduced energy consumption, and reduced chemical pollution. Their applications span food, textiles, feed, detergents, papermaking, leather, pharmaceuticals, as well as energy development and environmental protection. To maintain the activity of liquid enzyme preparations, it is currently common practice to aliquot them and store them in refrigerated containers.

[0003] A search revealed that utility model patent CN211392081U discloses a liquid enzyme preparation preservation device, including a box, a cooling mechanism, a dispensing mechanism, a handle, a threaded shaft, and a fixing frame. The box includes a cover, an upper box, and a lower box, which are connected by a threaded rotation. An opening is provided on the outer wall of the upper box, which is covered by a sealing cover. A transparent window is provided on the sealing cover, and a handle is provided on the upper part of the transparent window. The threaded shaft passes through the center of the cover and extends into the upper box. The handle is fixedly connected to the free end of the threaded shaft located outside the cover. The fixing frame is detachably connected to the threaded shaft and has a plurality of placement holes for the dispensing mechanism. The cooling mechanism is fixedly located inside the lower box. This patent has a simple structure and facilitates the handling of liquid enzyme preparations. However, the above patent still has the following shortcomings: when the liquid enzyme preparation dispensing mechanism is taken out from the sealed cover, the cold air in the box will inevitably be lost, which will affect the preservation effect of other remaining liquid enzyme preparations. At the same time, when taking out liquid enzyme preparations, it is not convenient to manually turn the handle to drive multiple liquid enzyme preparation dispensing mechanisms to rotate. When there are many liquid enzyme preparations, the force required for rotation is large. Therefore, we have proposed a liquid enzyme preparation preservation device. Utility Model Content

The top surface of the heat exchange plate 19 is in contact with the bottom surface of the partition 5.

[0027] In this embodiment, the high-temperature and high-pressure refrigerant is delivered to the condenser unit 15 through the conduit 17 by the compressor 14. The condenser unit 15 allows the high-temperature and high-pressure refrigerant to exchange heat with the air, thereby cooling the refrigerant. The high pressure is converted to low pressure by the thin copper tube in the condenser unit 15, and the low-temperature and low-pressure refrigerant enters the evaporator coil 16. Through the heat exchange plate 19, the evaporator coil 16 exchanges heat with the inner cavity of the refrigerator compartment 2, thereby cooling the inner cavity of the refrigerator compartment 2. The refrigerant in the evaporator coil 16 then flows back to the compressor 14. This is an existing refrigeration technology and will not be described in detail.

[0028] For details, please refer to Figure 3 The inner wall of the refrigerator compartment 2 is provided with multiple mounting holes 20, and a temperature sensor 21 is fixedly installed in the inner cavity of the mounting hole 20.

[0029] In this embodiment, temperature sensor 21 is used to measure the temperature of the space between each pair of partitions 5 to ensure that the storage tube 9 inside the partition 5 is at a suitable storage temperature.

[0030] For details, please refer to Figure 1 The side of the housing 1 has multiple ventilation holes 23, and the ends of the ventilation holes 23 are connected to the inner cavity of the refrigeration chamber 13.

[0031] In this embodiment, it is ensured that external air can enter the inner cavity of the cooling chamber 13 and the condenser unit 15 for heat exchange.

[0032] For details, please refer to Figures 1 to 3 A control panel 22 is fixedly installed on the side of the housing 1. The control panel 22 is electrically connected to the stepper motor 3, the compressor 14, and the temperature sensor 21.

[0033] In this embodiment, the stepper motor 3 and the compressor 14 are controlled by the control panel 22, the temperature detected by the temperature sensor 21 is displayed by the control panel 22, and the device is powered by the power supply of the external device.

[0034] For details, please refer to Figure 2 and Figure 3 The end face of partition 5 is in contact with the inner wall of the refrigerator compartment 2.

[0035] In this embodiment, the space between every two partitions 5 is ensured to be isolated from each other.

[0036] For details, please refer to Figure 1 The inner wall of the retrieval slot 10 and the side of the transparent arc-shaped sealing plate 11 are attached together.

[0037] In this embodiment, the transparent arc-shaped sealing plate 11 is kept airtight to the retrieval slot 10 to prevent cold air from escaping from the inner cavity of the refrigerator compartment 2.

[0038] Working principle: In use, place the liquid enzyme preparation to be stored into the storage tube 9 and place the storage tube 9 into the insertion hole 7 on the support frame 6. The bottom end of the storage tube 9 is supported by the support net 8. At the same time, the compressor 14, condenser unit 15, evaporator coil 16 and conduit 17 work together to generate cold air in the inner cavity of the refrigerator compartment 2, thereby preserving the liquid enzyme preparation in the storage tube 9 at a low temperature. When it is necessary to remove the liquid enzyme preparation from the inner cavity of the refrigerator compartment 2, start the stepper motor 3 to drive the rotating column 4 and the partition 5 to rotate. Observe the position of the storage tube 9 between the two partitions 5 through the transparent arc-shaped sealing plate 11. When the storage tube 9 to be removed is aligned with the retrieval slot 10, hold the lever 12 to move the transparent arc-shaped sealing plate 11 upward. At this time, the storage tube 9 between the two partitions 5 is removed without affecting the temperature of the storage tubes 9 stored between the other two partitions 5.
