[0002] In the processing of traditional Chinese medicine, liquid Chinese medicine is often made into freeze-dried products for convenient storage, transportation and use. Vacuum freeze-drying technology is a technology that freezes liquid materials into solids at low temperatures, and then removes the water in the materials by sublimation into gaseous state in a vacuum environment, thereby obtaining freeze-dried products.

[0003] The structure of the racks in some existing traditional vacuum freeze dryers is relatively fixed, which makes it inconvenient to put in and take out the trays containing materials. After the trays are filled with medicinal liquid, pushing the trays directly can easily cause them to shake or tilt, resulting in spillage of the medicinal liquid. This is not practical. In addition, some traditional methods of vacuum freeze drying of medicinal liquids directly pour the liquid into the trays, but medicinal extracts such as extracts and polysaccharides will stick to the surface of the trays after freeze drying, making it difficult to remove the materials and also hindering the subsequent cleaning of the trays. Therefore, a vacuum freeze dryer is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a vacuum freeze dryer, which aims to improve the existing technology. The structure of the placement rack of some traditional vacuum freeze dryers is relatively fixed, which makes it inconvenient to put in and take out the trays for placing materials.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a vacuum freeze dryer, including a body 1, which is a vacuum freeze dryer. Vacuum freeze drying is a drying technology that first freezes water-containing substances into a solid state, and then directly sublimates the ice into water vapor and removes it under vacuum. Its core process is divided into three stages: freezing, sublimation, and desorption. Since it is a common existing technology in this field, it will not be described in detail here. A drying chamber 11 is provided in the middle of the body 1, which is used to cooperate with the placement component 2 and to cooperate in the vacuum freeze drying of traditional Chinese medicine liquid. A cover plate is provided at the front of the body 1. The placement component 2 is placed in the drying chamber 11. The placement component 2 is provided in the middle of the body 1, which is used to cooperate with the placement tray 3. Multiple trays 3 are placed in the middle of the placement component 2 for holding the medicine liquid.

[0023] like Figure 3 - Figure 5As shown, the placement assembly 2 includes a placement frame 21, which is used to connect various components. Multiple placement pieces 22 are installed in the middle of the placement frame 21, which are used to place the tray 3. The inner walls of the placement frame 21 are provided with sliding grooves 211 on both the left and right sides, which are used to connect the sliding rods 223. The two sliding grooves 211 are provided with auxiliary grooves 212 on the side that are far apart from each other, which are used to connect the auxiliary blocks 224 and to connect the placement pieces 22 to the placement frame 21, so as to prevent the placement pieces 22 from detaching. Multiple ball bearings 213 are rotatably connected to the upper and lower sides of the sliding grooves 211, which are used to reduce the friction when the placement pieces 22 move, so that the pushing and pulling of the placement pieces 22 is more stable.

[0024] Furthermore, the placement component 22 includes a placement plate 221, which is used to connect various components. Baffles 222 are fixedly connected to the front and rear sides of the placement plate 221, which are used to limit the position of the tray 3 and assist in pulling the placement plate 221. Slide rods 223 are fixedly connected to the left and right sides of the placement plate 221, which are used to connect the placement component 22. The slide rods 223 are slidably connected to the slide grooves 211. Auxiliary blocks 224 are fixedly connected to the rear of the two slide rods 223 on the side away from each other, which are used to connect the placement component 22 and the placement rack 21. The auxiliary blocks 224 are slidably connected to the auxiliary grooves 212. Guide grooves 225 are opened on the upper and lower sides of the slide rods 223, which are adapted to the ball bearings 213. The ball bearings 213 are movably connected to the guide grooves 225.

[0025] Please see Figure 6 The interior of the tray 3 is lined with a partition paper 31, which can be DuPont paper or the like. The upper part of the tray 3 is movably connected to a limiting sleeve 32, which can be made of plastic or rubber and has a certain deformation capability. The edge of the partition paper 31 is fitted onto the upper edge of the tray 3 and is positioned between the limiting sleeve 32 and the tray 3 to cooperate with the limiting sleeve 32 in limiting the position, thereby fixing the partition paper 31. A retaining ring 33 is fixedly connected to the upper part of the outer wall of the tray 3. A retaining groove 34 is opened on the inner wall of the limiting sleeve 32. The retaining ring 33 engages with the retaining groove 34 to improve the stability of the connection between the limiting sleeve 32 and the tray 3.

[0026] Working principle: First, place the placement component 2 into the drying chamber 11, then pull the baffle 222, causing the placement plate 221 to be pulled forward. At this time, the slide rod 223 fixed to the placement plate 221 will slide in the slide groove 211. Through the cooperation of the ball bearing 213 and the guide groove 225, the friction of the slide rod 223 when it moves can be reduced, making the pushing and pulling of the placement plate 221 more stable and smooth. At the same time, the auxiliary block 224 will slide in the auxiliary groove 212. When the auxiliary block 224 moves to the front of the auxiliary groove 212, the placement plate 221 will be completely pulled out and can no longer move. Then, the tray 3 can be placed on the placement plate 221.

[0027] Before using tray 3, the partition paper 31 should be laid inside tray 3, with its edge wrapped around the edge of tray 3. Then, the limiting sleeve 32 should be clipped onto tray 3 to fix the edge of the partition paper 31. When installing the limiting sleeve 32, ensure that the retaining ring 33 on tray 3 is fully engaged in the retaining groove 34 to ensure the stability of the limiting sleeve 32. After tray 3 is placed on the placement piece 22, the Chinese medicine to be dried can be poured into the partition paper 31 of tray 3. Then, the tray 3 containing the medicine liquid is pushed into the placement rack 21. After all trays 3 are placed, the cover of the machine body 1 can be closed, and then the freeze dryer can be turned on to freeze dry the medicine liquid in tray 3.

[0028] Once the liquid medicine has dried, open the cover of the machine body 1, pull the baffle 222 to make the placement piece 22 extend the tray 3 on its upper part, and then take out the tray 3. Then remove the limiting sleeve 32 from the tray 3, and then take out the partition paper 31 from the tray 3 to complete the material handling.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
