Technical Field
[0001] This utility model relates to the field of high-speed refrigerated centrifuges, and in particular to a high-speed refrigerated centrifuge for food testing. Background Technology
[0002] A high-speed refrigerated centrifuge is a laboratory device that combines high-speed rotation with low-temperature refrigeration. Its core principle is to separate substances with different densities and sedimentation coefficients in a sample by using the powerful centrifugal force generated by high-speed rotation. At the same time, the refrigeration system precisely controls the temperature of the centrifuge chamber (usually ranging from -20°C to 4°C) to prevent heat-sensitive samples (such as proteins, nucleic acids, cells, etc.) from denaturing or degrading due to increased temperature.
[0003] However, existing high-speed refrigerated centrifuges require a separate sealing cap to be installed on the centrifuge tube rotor to fix the centrifuge tube during use, which makes the operation process cumbersome and affects the testing efficiency.
[0004] Therefore, it is essential to invent a high-speed refrigerated centrifuge for food testing that reduces the number of operational steps. Utility Model Content

[0029] Example
[0030] Reference Figure 1-6A high-speed refrigerated centrifuge for food testing includes a casing 1, wherein: a sealing cover 3 is installed on the top of the casing 1 by a hydraulic support rod 2 so that when the sealing cover 3 is opened, the hydraulic support rod 2 supports the sealing cover 3 to ensure the stability of the sealing cover 3; a centrifugal assembly is fixedly installed in the casing 1 so that centrifugal tubes containing food are centrifuged by the centrifugal assembly; a sealing component 9 corresponding to the centrifugal assembly is fixedly installed on the bottom surface of the sealing cover 3 so that when the sealing cover 3 is closed, the sealing component 9 can seal the cavity 81 of the rotor disk 8, thereby ensuring the stability of the centrifugal tube in the centrifugal tube cavity 82;
[0031] Specifically, the centrifuge assembly includes an inner tank 4, a motor 5, and a rotor disc 8. The inner tank 4 is fixedly installed in the casing 1 with its opening facing upwards, so that a sealed space can be formed during centrifugation through the inner tank 4 and the sealing cover 3. The motor 5 is fixedly installed inside the casing 1, and the output end of the motor 5 rotates into the interior of the inner tank 4. A quick-release assembly is fixedly installed on the output end of the motor 5, and the quick-release assembly rotates within the inner tank 4. The rotor disc 8 is plugged and pulled into the quick-release assembly, so that the rotor disc 8 can be replaced individually through the quick-release assembly. The rotor disc 8 rotates within the inner tank 4.
[0032] Specifically, a cavity 81 is coaxially formed on the upper surface of the rotor disk 8 to provide contact space for the flexible pad 93. Several centrifuge tubes 82 are evenly formed on the upper side of the rotor disk 8 in an even number. The centrifuge tubes 82 are arranged in a ring array with the cavity 81 as the center to ensure balance during centrifugation. The opening of each centrifuge tube 82 is located in the cavity 81 so that after the sealing cover 3 is closed, the flexible pad 93 is located in the cavity 81, thereby simultaneously sealing the centrifuge tubes in each centrifuge tube 82, ensuring the stability of the centrifuge tubes in the centrifuge tubes 82, and preventing the centrifuge tubes from shifting during centrifugation.
[0033] Specifically, the sealing assembly 9 includes a sealing disc 91, a rotating disc 92, and a flexible pad 93. One side of the sealing disc 91 is fixedly connected to the bottom surface of the sealing cover 3, and the other side of the sealing disc 91 is coaxially rotatably connected to the rotating disc 92. With this structure, the rotating disc 92 and the flexible pad 93 can rotate together during the rotation of the rotor disc 8. The other side of the rotating disc 92 is fixedly installed with a flexible pad 93 for contacting the upper surface of the rotor disc 8.
[0034] The flexible pad 93 uses existing technology, such as rubber pads in the prior art;
[0035] Specifically, a refrigeration system with a compressor as its core is fixedly installed inside the casing 1. The evaporator tube 15 of the refrigeration system is spirally coiled around the outer surface of the inner liner 4 so as to exchange heat between the evaporator tube 15 and the inner liner 4, thereby freezing during the centrifugation process.
[0036] Since compressor-based refrigeration systems are a very mature technology, we will not go into too much detail about them here.
[0037] Specifically, ventilation holes 12 are provided on both sides of the chassis 1, and a cooling fan 13 is fixedly installed on one side of the chassis 1 so as to ventilate and dissipate heat on the components inside the chassis 1 through the ventilation holes 12 and the cooling fan 13. A lock body 14 with an upward opening is fixedly installed on the top of the chassis 1, and the latch 10 of the lock body 14 is fixedly installed on the bottom surface of the sealing cover 3 so as to ensure the stability of the sealing cover 3 after it is closed through the lock body 14 and the latch 10, and prevent the sealing cover 3 from being opened accidentally.
[0038] The lock body 14 adopts existing technology, such as electronic locks or ordinary mechanical locks.
[0039] Specifically, the motor 5, cooling fan 13, and the control system of the refrigeration system are fixedly installed inside the chassis 1, and the control panel 11 of the motor 5, cooling fan 13, and refrigeration system is fixedly installed on the front side of the chassis 1 so that the motor 5, cooling fan 13, and refrigeration system can be controlled through the control panel 11.
[0040] The speed of motor 5 can be controlled by a speed control module, such as frequency conversion speed control. Since the speed control module is a very mature technology, it will not be discussed in detail here.
[0041] Specifically, several support pads 41 are evenly fixedly installed on the bottom surface of the inner liner 4. The support pads 41 are fixedly connected to the bottom surface inside the casing 1 so as to ensure the stability between the inner liner 4 and the casing 1. A truncated cone 42 is coaxially fixedly installed inside the inner liner 4. The output end of the motor 5 extends out from the top of the truncated cone 42 so as to ensure the stability of the output end of the motor 5.
[0042] Specifically, the quick-release assembly includes a support plate 6 and a positioning block 7. The support plate 6 is fixedly installed at the output end of the motor 5. Several positioning blocks 7 are evenly fixedly installed on the upper surface of the support plate 6. The bottom surface of the rotor disk 8 is provided with positioning holes 83 corresponding to the positioning blocks 7. The positioning blocks 7 and the positioning holes 83 are plugged and plugged in. With this structure, it is convenient to disassemble and replace the rotor disk 8 individually.
[0043] In this embodiment, when in use, the sealing cover 3 is opened, the centrifuge tubes containing food are evenly placed in the corresponding centrifuge tube cavities 82, and then the sealing cover 3 is closed. At this time, the flexible pad 93 is in the concave cavity 81, which simultaneously seals the centrifuge tubes in each centrifuge tube cavity 82, ensuring the stability of the centrifuge tubes in the centrifuge tube cavity 82 and preventing the centrifuge tubes from shifting during centrifugation.
[0044] After freezing and centrifugation, open the sealing cap 3, and the flexible pad 93 will separate from the cavity 81, allowing the centrifuge tube to be removed, making the process of taking out and putting in the centrifuge tube more convenient and flexible.
[0045] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
