AI Technical Summary
The existing freeze-dryer placing racks are likely to cause the placement tray to disengage in the freezing chamber, and the distance between the placement racks cannot be adjusted, which is difficult to adapt to the freezing treatment of substances of different sizes.
A freeze-dried sample insulation rack is designed, including a freeze-dried machine and a freeze-dried bracket. The freeze-dried bracket is equipped with a slidingly connected placement rack. The distance between the placement racks is adjustable, and the stable fixation of the placement rack is achieved through the moving handle and the return spring mechanism.
The problem of placing the tray in the freezing chamber is effectively avoided, and by adjusting the distance of the placement rack, it adapts to the freezing treatment of substances of different sizes, improving the insulation effect of freeze-dried samples and operating flexibility.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of freeze-drying machine placement racks, in particular to a freeze-dried sample insulation rack. Background Art
[0002] A lyophilizer (or Freeze Dryer) is a device used to stabilize and preserve sensitive substances through low-temperature drying technology. The freeze-drying process (also known as sublimation drying) involves rapidly freezing the substance and then directly converting the ice from a solid state to a gaseous state under a vacuum to remove water. This process preserves the structure, activity and composition of the substance, making it very suitable for use in biological products, pharmaceuticals, food and chemicals.
[0003] The freeze-dried sample insulation rack is a support rack used to keep samples in a low temperature environment during the freeze-drying process or during subsequent storage to prevent them from rehydrating, deteriorating or degrading in performance.
[0004] When in use, the material must first be placed in the refrigeration chamber of the freeze dryer for pre-cooling treatment, and the material temperature reaches -80°C, and then the drying process is carried out. The current placement rack is only used to support the placement plate. When this bracket is used, it is easy for the placement plate to separate from the placement rack when placed in the refrigeration chamber. In actual applications, when freezing and processing materials of different sizes, the distance between the current placement racks is fixed and cannot be adjusted.
[0005] Therefore, the utility model designs a freeze-dried sample insulation rack to solve the technical problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION
[0023] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-5The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.
[0024] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.
[0025] Embodiment 1, a freeze-dried sample insulation rack, comprising a freeze dryer 1 and a freeze drying rack 2, characterized in that:
[0026] The freeze dryer 1 is provided with a freezing chamber 3 and a cover 4 corresponding to the freezing chamber 3;
[0027] The freeze-drying support 2 is placed in the freezing chamber 3, and the freeze-drying support 2 is vertically spaced with an array of placement racks 5, and the array of placement racks 5 is slidably connected to the freeze-drying support 2;
[0028] The freeze-drying support 2 is provided with an array of positioning holes 6, the array of the placement rack 5 is provided with a mounting groove 7, a movable plate 8 is slidably connected in the mounting groove 7, a positioning block 9 corresponding to the positioning hole 6 is provided on the movable plate 8, a return spring 10 is provided between the movable plate and the mounting groove 7, and a first handle 11 is provided on the movable plate 8;
[0029] The array described placement rack 5 is provided with a placement tray 12;
[0030] The freeze-drying support 2 includes a first support frame 13, a second support frame 14, a bottom plate 15 and a second handle 16. The first support frame 13 and the second support frame 14 are both connected to the bottom plate 15. The first support frame 13 is arched, and the other end of the second support frame 14 is connected to the first support frame 13. The handle is fixedly arranged on the upper end of the first support frame 13.
[0031] The first support frame 13 is provided with a sliding groove 17 , the placement frame 5 is provided with a sliding block matched with the sliding groove 17 , and the second support frame 14 is provided with an array of positioning holes 6 .
[0032] When in use, the distance between the placement racks 5 is adjusted according to the actual size of the material. By moving the first handle 11, the movable plate 8 is driven to slide in the installation groove 7, which overcomes the elastic force of the return spring 10 on the one hand and makes the positioning block 9 disengage from the positioning hole 6 on the other hand. At this time, the placement rack 5 can be moved for adjustment until it is adjusted to a suitable size.
[0033] After the adjustment is completed, the placement tray 12 filled with materials is placed on the placement rack 5. Since the placement rack 5 is a semi-circular arc plate, the placement tray 12 is supported by the semi-circular arc plate to prevent it from falling off the placement rack 5.
[0034] Finally, the placing rack 5 is placed as a whole into the freezing chamber 3 of the freeze dryer 1 for precooling to precool the material to -80°C.
[0035] Embodiment 2, based on embodiment 1, the placement rack 5 of the array is provided with a baffle 18, the baffle 18 is provided with a male Velcro, and the placement plate 12 is provided with a female Velcro corresponding to the male Velcro;
[0036] The bottom of the placement rack 5 is provided with an anti-skid pad.
[0037] When the placement tray 12 is placed on the placement rack 5, the male Velcro and the female Velcro further strengthen the firmness of the placement tray 12. The reason for not using magnets is that placing magnetic materials in the freezing chamber of the freeze dryer may not be an ideal choice, because the magnetic materials may interact with the freeze-dried samples, causing the samples to be contaminated or interfered by the magnetic field. This may have an adverse effect on the experimental results or production quality.
[0038] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
