[0014] Beneficial effects

[0015] Compared with the prior art, this utility model provides a freeze storage tray for lyophilized powder with fixed marking thickness, which has the following advantages:

[0016] 1. In this solution, the tray is used to hold the material to be freeze-dried. The amount of material is easily controlled by the scale. The sealing cap is used to seal the tray. The adjusting cap can be rotated on the sealing cap to adjust the distance between the liquid level inside the tray and the adjusting cap, which facilitates the adjustment of the thickness of the freeze-dried material and ensures the flatness of the freeze-dried material. By controlling the thickness of the freeze-dried material, the risk of boiling over is reduced. The installation protrusion facilitates the operation of the adjusting cap. At the same time, the installation protrusion and the corresponding mating groove cooperate to facilitate the stacking of multiple trays.

[0017] 2. In this solution, the disposable non-stick film adheres tightly to the inner wall of the tray, and the edge of the disposable non-stick film is overturned onto the sealing cap. The disposable non-stick film effectively prevents the loss and contamination of the freeze-dried powder during operation. At the same time, after the freeze-dried material becomes a solid block, the disposable non-stick film makes it easy to remove the entire material for convenient packaging and storage.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example:

[0027] Please see Figure 1-5 A freeze storage tray for lyophilized powder with fixed thickness markings, comprising:

[0028] Disc 1, the inner wall of disc 1 is engraved with scale 2; and

[0029] The liquid level adjustment mechanism 3 includes a sealing cover 301, which is installed on the top of the pan body 1. The top of the sealing cover 301 has a threaded hole, and an adjustment cover 302 is threaded inside the threaded hole. The top of the adjustment cover 302 is fixedly connected with multiple mounting protrusions 303, and the bottom of the pan body 1 has multiple mating grooves 304.

[0030] In this embodiment, the tray 1 is used to hold the material to be freeze-dried. The amount of material held is easily controlled by the scale 2. The outer diameter of the sealing cap 301 is larger than the outer diameter of the tray 1, which facilitates sealing of the tray 1. The outer diameter of the adjusting cap 302 is adapted to the inner diameter of the tray 1. The adjusting cap 302 rotates on the sealing cap 301 to easily adjust the distance between the liquid level inside the tray 1 and the adjusting cap 302, which facilitates the adjustment of the thickness of the freeze-dried material and ensures the flatness of the freeze-dried material. By controlling the thickness of the freeze-dried material, the risk of boiling over is reduced. The adjusting cap 302 is easily operated by the installed protrusion 303. At the same time, the installed protrusion 303 and the corresponding docking groove 304 cooperate to facilitate the stacking of multiple trays 1.

[0031] Please refer to the specific details. Figure 4 As shown, a disposable non-stick film 4 is provided inside the disc body 1.

[0032] In this embodiment, the disposable non-stick film 4 is tightly attached to the inner wall of the tray 1, and the edge of the disposable non-stick film 4 is overturned on the sealing cap 301. The disposable non-stick film 4 effectively prevents the freeze-dried powder from being lost or contaminated during operation. At the same time, after the freeze-dried material becomes a solid block, the disposable non-stick film 4 can be used to easily remove the entire material for convenient packaging and storage.

[0033] Please refer to the specific details. Figure 4-5 As shown, the outer wall of the disc body 1 is hinged with multiple buckles 5, and each buckle 5 is fitted with an elastic anti-slip roller 6.

[0034] In this embodiment, the buckle 5 facilitates the positioning of the sealing cover 301, improving the installation and sealing effect of the sealing cover 301, and the elastic anti-slip roller 6 improves the positioning effect of the sealing cover 301.

[0035] Please refer to the specific details. Figure 4 As shown, the top of the adjusting cover 302 has multiple mounting holes 1 and 2, and each mounting hole 1 and mounting hole 2 has a mounting cover 7 threaded inside.

[0036] In this embodiment, mounting hole one and mounting hole two are used for installing centrifuge tubes. In the initial state, mounting hole one and mounting hole two are sealed by mounting cover 7. When it is necessary to drain the residual liquid on the adjusting cover 302, the centrifuge tube is installed into the corresponding mounting hole one or mounting hole two, and then the residual liquid on its surface can be drained into the centrifuge tube by inverting the adjusting cover 302, thus avoiding waste of resources.

[0037] Please refer to the specific details. Figure 4 As shown, each mounting cover 7 has a sealing ring 8 fitted on its outer surface.

[0038] In this embodiment, the sealing effect of the mounting cover 7 is improved by the sealing ring 8.

[0039] Please refer to the specific details. Figure 4 As shown, each mounting cover 7 has a handle 9 fixedly connected to one side of its outer wall.

[0040] In this embodiment, the handle 9 facilitates the installation and removal of the cover 7.

[0041] Working principle: In use, the disposable non-stick film 4 is installed inside the tray 1, and the material to be freeze-dried is placed on the disposable non-stick film 4 inside the tray 1. The amount of material put into the tray 1 is controlled by the scale 2. The sealing cover 301 is placed on the tray 1 and fixed by the buckle 5 and the elastic anti-slip roller 6. When it is necessary to control the thickness of the freeze-dried material, the adjusting cover 302 is rotated by the mounting protrusion 303 to raise and lower the adjusting cover 302 and adjust the distance between it and the liquid surface of the material. After adjustment, the tray 1 is placed inside the freeze dryer for freeze-drying. After freeze-drying, the buckle 5 is opened and the sealing cover 301 and adjusting cover 302 are removed. The disposable non-stick film 4 and the material can be removed together. When it is necessary to drain the residual liquid on the adjusting cover 302, the corresponding mounting cover 7 is unscrewed by the handle 9, the centrifuge tube is screwed into the corresponding mounting hole one or mounting hole two, the adjusting cover 302 is inverted, and the drained liquid is recovered through the centrifuge tube.

[0042] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
