Description

Technical Field

[0001] This utility model relates to the field of freeze-drying technology, and in particular to a freeze-drying raw material holding device. Background Technology

[0002] Freeze-drying technology, also known as vacuum freeze-drying technology, works by rapidly freezing raw materials at low temperatures and then sublimating the water directly from a solid to a gaseous state in a vacuum environment, thus removing moisture from the raw materials. During this process, due to the low temperature and minimal oxygen in a vacuum environment, the nutritional components, aromatic compounds, and active substances of the raw materials are preserved to the maximum extent, while preventing the growth of microorganisms and the action of enzymes, ensuring the quality and stability of the raw materials. Through freeze-drying technology, fresh vegetables can be processed into vegetable powders (such as freeze-dried okra powder, freeze-dried daylily powder, freeze-dried broccoli powder, etc.). These vegetable powders not only retain the original nutritional components and flavor of the vegetables but also have advantages such as small size, light weight, easy transportation, and long-term storage.

[0003] Most vegetable powder manufacturers use stainless steel trays for freeze drying. However, this freeze drying method has serious drawbacks. Once the vegetable powder raw materials stick to the bottom of the stainless steel tray, they need to be scraped off with a tool, which is very troublesome. In addition, the stainless steel trays are open for freeze drying, which can easily cause the vegetable powder raw materials to fly around and lead to waste.

[0004] Therefore, it is necessary to provide a new freeze-dried raw material holding device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a freeze-dried raw material holding device.

[0006] The freeze-dried raw material holding device provided by this utility model includes a stainless steel holding cylinder. One end of the stainless steel holding cylinder is provided with an opening, and the other end of the stainless steel holding cylinder is fixedly fitted with a side plate. A semi-circular pusher plate for pushing the freeze-dried raw material outward and a semi-circular sealing plate for sealing the opening are installed inside the stainless steel holding cylinder. The semi-circular pusher plate is slidably installed in the stainless steel container and abuts against the inner wall of the stainless steel container. The semi-circular pusher plate is fixedly connected to the semi-circular sealing plate by two symmetrically distributed central connecting rods. The stainless steel container is equipped with a protective component for shielding the upper opening of the stainless steel container.

[0007] Preferably, two symmetrically distributed connecting frames are fixedly installed on the semi-circular push plate, and the connecting frames pass through the sliding groove opened in the stainless steel container and extend into the mounting hole opened in the stainless steel container. The sliding groove and the mounting hole are interconnected. The central connecting rod is slidably installed in the mounting hole. One end of the central connecting rod is fixedly connected to the extension end of the connecting frame, and the other end of the central connecting rod extends out of the mounting hole and is fixedly connected to the inner wall of the semi-circular sealing plate.

[0008] Preferably, a magnetic plate B is fixedly fitted into the inner wall of the side plate, and a magnetic plate A is fixedly installed on the wall of the semi-circular pusher plate corresponding to the magnetic plate B, and the magnetic plates A and B have opposite magnetic properties.

[0009] Preferably, the protective component includes a V-shaped breathable membrane, and a plurality of V-shaped breathable membranes are provided and the plurality of V-shaped breathable membranes are fixedly connected in sequence. A semi-circular rod is fixedly fitted at the connection point of two V-shaped breathable membranes, and a collar is fixedly installed at the bottom of each semi-circular rod. A central semi-circular plate and a fixed semi-circular plate are fixedly fitted at the opposite ends of the first and last two V-shaped breathable membranes, respectively.

[0010] Preferably, the central semicircular plate is fixedly fitted onto the semicircular pusher plate, the fixed semicircular plate is fixedly fitted onto the side of the stainless steel container near the opening, and the two collars on the semicircular rod are respectively fitted onto the two central connecting rods and slidably connected to the central connecting rods.

[0011] Preferably, the stainless steel container has an arc-shaped groove at one end with an opening for engaging the semi-circular sealing disc.

[0012] Preferably, multiple support legs are fixedly installed on both sides of the stainless steel container.

[0013] Compared with related technologies, the freeze-dried raw material holding device provided by this utility model has the following beneficial effects: When the semi-circular pusher plate is pulled, causing the semi-circular sealing disc to seal the opening, the central semi-circular plate slides synchronously with the pusher plate and moves away from the fixed semi-circular plate at the opening. This causes the V-shaped breathable membranes to be stretched as the collar slides inward along the central rod. Thus, several V-shaped breathable membranes form a canopy structure that covers the stainless steel container, reducing the risk of freeze-dried material scattering due to the open top of the container. The outward pusher plate pushes the freeze-dried material outward from the stainless steel container. Simultaneously, the semi-circular sealing disc separates from the opening under the outward push of the central rod. Therefore, the freeze-dried material slides out of the stainless steel container under the outward push of the semi-circular pusher plate and is poured into a sterile packaging bag or container for storage. Because the semi-circular pusher plate abuts against the inner wall of the stainless steel container, the freeze-dried material adhering to the inner wall can be scraped off without the need for other tools, making the process simple and convenient.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 6 This utility model provides a freeze-dried raw material holding device, which includes a stainless steel holding cylinder 1, a semi-circular pusher plate 2, a semi-circular sealing plate 3, and a protective component 7.

[0019] In the embodiments of this utility model, please refer to Figures 1 to 6One end of the stainless steel container 1 has an opening 1a, and the other end of the stainless steel container 1 is fixedly fitted with a side plate 11. Inside the stainless steel container 1, a semi-circular pusher plate 2 for pushing out freeze-dried raw materials and a semi-circular sealing disc 3 for sealing the opening 1a are installed. The semi-circular pusher plate 2 is slidably installed in the stainless steel container 1 and abuts against the inner wall of the stainless steel container 1. The semi-circular pusher plate 2 is fixedly connected to the semi-circular sealing disc 3 by two symmetrically distributed connecting rods 4. Specifically, two symmetrically distributed connecting brackets 21 are fixedly installed on the semi-circular pusher plate 2, and the connecting brackets 21 pass through... The stainless steel container 1 has a sliding groove 1c that extends into the mounting hole 1b. The sliding groove 1c and the mounting hole 1b are interconnected. The central connecting rod 4 is slidably installed in the mounting hole 1b. One end of the central connecting rod 4 is fixedly connected to the extension end of the connecting frame 21, and the other end of the central connecting rod 4 extends out of the mounting hole 1b and is fixedly connected to the inner wall of the semi-circular sealing plate 3. A magnetic B plate 6 is fixedly embedded in the inner wall of the side plate 11. A magnetic A plate 5 is fixedly installed on the wall of the semi-circular pusher plate 2 corresponding to the magnetic B plate 6, and the magnetic A plate 5 and the magnetic B plate 6 have opposite magnetic properties.

[0020] It should be noted that: before the freeze-dried raw material (such as freeze-dried vegetable powder) is put into the stainless steel container 1, the semi-circular pusher plate 2 is pulled so that the semi-circular pusher plate 2 slides along the inside of the stainless steel container 1 until the magnetic A plate 5 on the semi-circular pusher plate 2 and the magnetic B plate 6 on the side plate 11 attract each other. At this time, the semi-circular sealing plate 3 slides down to the opening 1a by the pull of the central connecting rod 4 and seals the opening 1a. Then the freeze-dried raw material is put into the stainless steel container 1. After that, the stainless steel container 1 is put into the freeze dryer and the freeze dryer door is closed, and the freeze drying program is started. After the freeze-drying process is completed, open the freeze-drying chamber door, take out the stainless steel container 1, and then push the semi-circular pusher plate 2 outward so that the semi-circular pusher plate 2 slides outward along the stainless steel container 1. At this time, the semi-circular pusher plate 2 pushes the freeze-dried raw material in the stainless steel container 1 outward. At the same time, the semi-circular sealing plate 3 is separated from the opening 1a by the outward pushing action of the central connecting rod 4. Therefore, the freeze-dried raw material slides away from the stainless steel container 1 along the opening 1a under the outward pushing action of the semi-circular pusher plate 2 and is poured into a sterile packaging bag or packaging barrel for storage. Since the semi-circular pusher plate 2 abuts against the inner wall of the stainless steel container 1, the freeze-dried raw material attached to the inner wall of the stainless steel container 1 can be scraped off without the need for other tools, which is simple and convenient. Among them, the stainless steel container 1 has an arc-shaped groove 1a1 at one end with an opening 1a for engaging the semi-circular sealing disc 3, thereby improving the sealing performance after the semi-circular sealing disc 3 abuts against the opening 1a. The stainless steel container 1 has multiple support legs 12 fixedly installed on both sides of its side walls, which improves the stability of the stainless steel container 1 after it has been filled with freeze-dried raw materials.

[0021] In the embodiments of this utility model, please refer to Figures 1 to 6 The stainless steel container 1 is provided with a shielding component 7 for shielding the upper cavity of the stainless steel container 1. The shielding component 7 includes a V-shaped breathable membrane 71. Several V-shaped breathable membranes 71 are provided and are fixedly connected in sequence. A semi-circular rod 72 is fixedly fitted at the connection of two V-shaped breathable membranes 71. A collar 73 is fixedly installed at the bottom of each semi-circular rod 72. A central semi-circular plate 74 and a fixed semi-circular plate 75 are fixedly fitted at the opposite ends of the two V-shaped breathable membranes 71, respectively. The central semi-circular plate 74 is fixedly fitted on the semi-circular pusher plate 2. The fixed semi-circular plate 75 is fixedly fitted on the side of the stainless steel container 1 near the opening 1a. The two collars 73 on the semi-circular rod 72 are respectively fitted on the two central rods 4 and are slidably connected to the central rods 4.

[0022] It should be noted that when the semicircular pusher plate 2 is pulled to make the semicircular sealing plate 3 seal the opening 1a, the central semicircular plate 74 slides synchronously with the semicircular pusher plate 2 and moves away from the fixed semicircular plate 75 at the opening 1a. As a result, each V-shaped breathable membrane 71 is stretched as the collar 73 slides inward along the central rod 4. Therefore, several V-shaped breathable membranes 71 form a canopy structure to cover the stainless steel container 1, reducing the risk of freeze-dried raw materials flying due to the open top of the stainless steel container 1. When the outward push of the semi-circular pusher plate 2 causes the semi-circular pusher plate 2 to discharge the freeze-dried raw material in the stainless steel container 1, the central semi-circular plate 74 slides synchronously with the semi-circular pusher plate 2 and approaches the fixed semi-circular plate 75 at the opening 1a, so that each V-shaped breathable membrane 71 is compressed as the collar 73 slides outward along the central rod 4. In this embodiment: when the stainless steel container 1 is covered by a canopy structure consisting of several V-shaped breathable membranes 71, both ends of the canopy structure and the stainless steel container 1 are provided with upper semi-circular openings. At this time, the freeze-dried raw materials are put into the stainless steel container 1 through the upper semi-circular openings for storage. It is worth noting that because the bottom of the stainless steel container 1 is arc-shaped, it can better contact the cooling system of the freeze dryer, thereby improving heat transfer efficiency. This helps to remove moisture from the freeze-dried raw materials more quickly during the freeze-drying process, shortening the freeze-drying time and improving production efficiency. At the same time, the arc-shaped bottom design of the stainless steel container 1 helps the freeze-dried raw materials to slide or be poured out more easily after freeze-drying, reducing the difficulty and time of manual cleaning. Furthermore, this arc-shaped bottom design also helps to distribute the freeze-dried raw materials more evenly on the tray during the freeze-drying process, avoiding localized over-drying or over-wetting. The arc-shaped bottom of the stainless steel container 1 is also more structurally reasonable and can withstand greater pressure and weight, which is especially important for freeze-dried raw materials that need to be stored or transported for a long time, ensuring their safety and stability.

[0023] The working principle of the freeze-dried raw material holding device provided by this utility model is as follows: Before the freeze-dried raw material (such as vegetable powder) is placed into the stainless steel container 1, the semi-circular pusher plate 2 is pulled to slide along the inside of the stainless steel container 1 until the magnetic plate A 5 on the semi-circular pusher plate 2 and the magnetic plate B 6 on the side plate 11 attract each other. At this time, the semi-circular sealing disc 3 slides down towards the opening 1a and seals the opening 1a by the pull of the central connecting rod 4. At the same time as the semi-circular pusher plate 2 is pulled to seal the opening 1a, the central connecting semi-circular plate 74 slides synchronously with the semi-circular pusher plate 2 and moves away from the fixed semi-circular plate 75 at the opening 1a. Thus, each V-shaped breathable membrane 71 moves with the collar 73. While sliding along the central connecting rod 4, it is stretched, so several V-shaped breathable membranes 71 form a canopy structure to cover the stainless steel container 1, reducing the risk of freeze-dried raw materials flying due to the open top of the stainless steel container 1. After the canopy structure formed by several V-shaped breathable membranes 71 covers the stainless steel container 1, both the canopy structure and the two ends of the stainless steel container 1 are provided with upper semi-circular openings. At this time, the freeze-dried raw materials are put into the stainless steel container 1 through the upper semi-circular openings for storage. Then, the stainless steel container 1 is put into the freeze dryer and the freeze dryer door is closed, and the freeze drying program is started. After the freeze-drying process is completed, open the freeze-drying chamber door, remove the stainless steel container 1, and then push the semi-circular pusher plate 2 outward so that it slides along the outside of the stainless steel container 1. At this time, the semi-circular pusher plate 2 pushes the freeze-dried raw material in the stainless steel container 1 outward. Simultaneously, the semi-circular sealing disc 3 separates from the opening 1a under the pushing action of the central connecting rod 4. Therefore, the freeze-dried raw material slides away from the stainless steel container 1 along the opening 1a under the pushing action of the semi-circular pusher plate 2 and is poured into a sterile packaging bag or packaging drum for storage. Since the semi-circular pusher plate 2 abuts against the inner wall of the stainless steel container 1, the freeze-dried raw materials attached to the inner wall of the stainless steel container 1 can be scraped off without the need for other tools, which is simple and convenient. When the semi-circular pusher plate 2 pushes outward, the central semi-circular plate 74 slides synchronously with the semi-circular pusher plate 2 and approaches the fixed semi-circular plate 75 at the opening 1a. As a result, each V-shaped breathable membrane 71 is compressed as the collar 73 slides outward along the central rod 4.

[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
