Description

Technical Field

[0001] This utility model relates to the field of freeze dryer technology, and in particular to a material box for a freeze dryer. Background Technology

[0002] A freeze dryer is a device that freezes water-containing substances at low temperatures and then sublimates the water directly into a gaseous state in a vacuum environment, thereby removing moisture and preserving the substance. Its working principle is based on the three states of water, namely the conversion between solid, liquid and gas. Specifically, the freeze dryer first freezes the material below its freezing point, and then, under high vacuum, uses the principle of sublimation to directly sublimate the ice into water vapor, thereby removing the moisture from the material. It has a wide range of applications in many fields.

[0003] Existing freeze dryers have the following drawbacks during use: Before operation, existing freeze dryers require the use of containers to store materials, which need to be covered with film and sealed after being filled. The containers are then placed in an ultra-low temperature freezer for freezing. After freezing, the sealing film needs to be perforated with needles. Finally, the containers are moved into the freeze-drying chamber of the freeze dryer for cold drying. The process is cumbersome and complicated, and the containers are inconvenient to clean. Therefore, we propose a material box for freeze dryers. Utility Model Content

[0004] The main purpose of this utility model is to provide a material box for a freeze dryer. Through the material loading mechanism set on the top of the freeze dryer, the material can be loaded, covered, sealed and punched quickly, thereby improving the processing efficiency and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A material box for a freeze dryer includes a freeze dryer and a loading mechanism. The loading mechanism is located on the top of the freeze dryer and includes a support platform, a glass cover, a fixed plate, a spring A, a movable plate, a tray, a spring B, a pressure ring, and needles. The support platform is located on the top of the freeze dryer, and a glass cover is snapped onto the outer periphery of the top of the support platform. The top of the support platform supports the fixed plate, and a movable plate is mounted on the top of the fixed plate. Springs A are vertically installed between the fixed plate and the movable plate, as well as between adjacent movable plates, and are connected by springs A. Trays containing materials are inserted into the interior of both the fixed plate and the movable plate. A pressure ring is movably connected to the top of the tray through spring B. Needles are welded to the bottom of each movable plate.

[0007] Furthermore, it also includes a connecting mechanism. The pallet installation position is provided with a connecting mechanism, which includes an annular groove, a slot, and a post. The top of both the fixed plate and the movable plate are provided with an annular groove, and the bottom of both annular grooves are provided with slots. The bottom of both pallets is fixedly connected with posts. A connecting mechanism is provided between the pallet and the fixed plate and the movable plate. The top of both the fixed plate and the movable plate is provided with an annular groove structure. When the pallet is placed inside the fixed plate and the movable plate, the post at the bottom of the pallet is aligned with the slot at the bottom of the annular groove and inserted to fix the pallet inside the annular groove, which facilitates subsequent cold drying. The detachable structure facilitates quick installation and removal of the pallet. When removing materials, the pallet can be directly removed and supported by the post.

[0008] Furthermore, limit rods are installed on both sides of the top of the fixed plate, and the limit rods pass through the spring A and the interior of the movable plate; the limit rod structure plays a limiting role between the movable plates, keeping them in the same vertical direction.

[0009] Furthermore, grooves are provided on both sides of the top of the tray, and the springs B are installed inside the grooves; the springs B are installed inside the grooves as a whole, without affecting the fit between the pressure ring and the top of the tray.

[0010] Furthermore, the insert is positioned corresponding to the slot and inserted into the slot; the cooperation between the slot and the insert can limit the position of the tray after it is installed in place.

[0011] Compared with the prior art, this utility model has the following advantages: The top of the refrigerated dryer is equipped with a support structure. The fixed plate and the movable plate, as well as adjacent movable plates, are connected by spring A. The tray is inserted inside the fixed plate and the movable plate. During material pretreatment, the tray can be removed and the material can be directly loaded into the tray. After loading, the lifting pressure ring stretches the spring B, and the film is covered on the top of the tray while the film is at the bottom of the pressure ring. After the film is covered, the pressure ring is released, and the pressure ring is pressed down and fixed under the action of spring B to complete the sealing. Subsequently, the material is frozen. The frozen material is loaded from the tray and directly installed into the fixed plate or the movable plate. The top movable plate does not support the tray. After installation, only the movable plate needs to be pressed down to compress spring A until the needles at the bottom of the movable plate contact the film. After the membrane is perforated, freeze-drying can begin. A tray structure holds the material, which is then sealed directly by a pressure ring and film. A needle is used for rapid and uniform perforation. Compared to existing freeze dryer loading components, this method effectively holds materials, improves material pretreatment convenience, and reduces processing time. A connecting mechanism exists between the tray, the fixed tray, and the movable tray. Both the fixed and movable trays have annular grooves on their tops. When placing the tray inside the fixed and movable trays, the insert pins at the bottom of the tray are aligned with the slots at the bottom of the annular grooves and inserted to secure the tray, facilitating subsequent freeze-drying. A detachable structure allows for quick and easy installation and removal of the tray. When removing materials, the tray can be directly removed, supported by the insert pins.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1-3 As shown, a material box for a freeze dryer includes a freeze dryer 1 and a loading mechanism 2. The loading mechanism 2 is provided on the top of the freeze dryer 1. The loading mechanism 2 includes a support platform 201, a glass cover 202, a fixed plate 203, a spring A 204, a movable plate 205, a tray 207, a spring B 209, a pressure ring 210, and a needle 211. The support platform 201 is provided on the top of the freeze dryer 1, and the glass cover 202 is snapped onto the outer periphery of the top of the support platform 201. The top of the support platform 201 supports... There is a fixed plate 203 and a movable plate 205 is installed on the top of the fixed plate 203. Springs A204 are installed vertically between the fixed plate 203 and the movable plate 205 and between adjacent movable plates 205 and are connected by springs A204. A tray 207 for loading materials is inserted into the inside of the fixed plate 203 and the movable plate 205. A pressure ring 210 is movably connected to the top of the tray 207 by spring B209. A needle 211 is welded to the bottom of the movable plate 205.

[0018] The system also includes a connecting mechanism 3. The connecting mechanism 3 is installed at the mounting position of the tray 207. The connecting mechanism 3 includes an annular groove 301, a slot 302, and a post 303. The top of both the fixed plate 203 and the movable plate 205 has an annular groove 301, and the bottom of both annular grooves 301 has a slot 302. The bottom of the tray 207 is fixedly connected to a post 303. The connecting mechanism 3 is provided between the tray 207, the fixed plate 203, and the movable plate 205. The top of each of the 5 is provided with an annular groove 301 structure. When the tray 207 is placed inside the fixed plate 203 and the movable plate 205, the insert post 303 at the bottom of the tray 207 is aligned with the slot 302 at the bottom of the annular groove 301 and inserted to fix the tray 207 inside the annular groove 301, which is convenient for subsequent cold drying. The detachable structure facilitates the quick installation and removal of the tray 207. At the same time, when removing materials, the tray 207 can be directly removed and supported by the insert post 303.

[0019] The fixed plate 203 has limit rods 206 installed on both sides of its top. The limit rods 206 pass through the spring A204 and the interior of the movable plate 205. The tray 207 has grooves 208 on both sides of its top. The springs B209 are installed inside the grooves 208. The limit rods 206 limit the movement of the movable plates 205, keeping them in the same vertical direction. The springs B209 are installed inside the grooves 208, so as not to affect the fit between the pressure ring 210 and the top of the tray 207.

[0020] The insertion post 303 corresponds to the position of the slot 302 and is inserted into the slot 302; the cooperation between the slot 302 and the insertion post 303 can limit the position of the tray 207 after it is installed in place.

[0021] It should be noted that this utility model is a material box for a freeze dryer. In use, the top of the freeze dryer 1 is equipped with a support platform 201.

During the film coating process, the film is positioned at the bottom of the pressure ring 210. After film coating is completed, releasing the pressure ring 210 allows it to press down and fix the film position under the action of spring B209, thus completing the sealing. Subsequently, the material undergoes freezing treatment. The frozen material is loaded onto the tray 207 and directly installed into the fixed tray 203 or the movable tray 205. The topmost movable tray 205 does not support the tray 207. After installation, simply press down on the movable tray 205 to compress the spring A204 until it reaches the bottom of the movable tray 205. The needles 211 contact the film and complete the opening process, at which point the freeze-drying operation can begin. The tray 207 structure holds the material, and the pressure ring 210 directly seals the film. The needles 211 then perform rapid and uniform opening. Compared to existing freeze dryer loading components, this method effectively holds the material, improves the convenience of material pretreatment, and reduces process time. A connecting mechanism 3 is provided between the tray 207, the fixed tray 203, and the movable tray 205. The top is provided with an annular groove 301 structure. When the tray 207 is placed inside the fixed tray 203 and the movable tray 205, the insert post 303 at the bottom of the tray 207 is aligned with the slot 302 at the bottom of the annular groove 301 and inserted to fix the tray 207 inside the annular groove 301, which is convenient for subsequent cold drying. The detachable structure facilitates the quick installation and removal of the tray 207. At the same time, when removing materials, the tray 207 can be directly removed and supported by the insert post 303.
