Description

Technical Field

[0001] This utility model belongs to the field of freeze dryer technology, specifically relating to a freeze dryer that is easy to load and unload materials. Background Technology

[0002] A freeze dryer, short for vacuum freeze dryer, is a device that freezes water-containing substances at low temperatures and removes the solid ice by sublimation into gas under vacuum, resulting in freeze-dried substances with very low water content and rehydration properties. The working principle of a freeze dryer is based on the fact that water exists in three states: solid, liquid, and gas, which can interconvert and coexist. Freeze dryers originated from vacuum freeze-drying technology in the 1820s. In the 21st century, vacuum freeze-drying technology has been widely used in fields beyond pharmaceuticals, biological products, food, blood products, and active substances.

[0003] Existing freeze dryers that facilitate loading and unloading of materials can adjust the spacing of freeze drying plates by setting up support rods, screws and drive components to easily adapt to materials of different heights to meet usage needs. However, during use, it is impossible to remove all freeze drying plates at once, which makes loading and unloading of materials quite troublesome and affects use. In addition, during use, the freeze dryer will shift due to vibration, which may cause it to scrape against the outer wall. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a freeze dryer that facilitates material loading and unloading, featuring convenient unloading and a fixing device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a freeze dryer for easy loading and unloading of materials, comprising a freeze drying chamber, a loading mechanism provided at the lower inner end of the freeze drying chamber, a freeze drying plate provided on one side of the loading mechanism, a through hole provided at the top of the freeze drying plate, a glass door provided on one side of the freeze drying chamber, and a placement mechanism provided at the bottom of the freeze drying chamber. The loading mechanism includes a slide rail, a base plate is provided on the inner side of the slide rail, an insertion hole is provided on the top of the base plate, a pin is provided on the top of the slide rail near the base plate, and a connecting mechanism is provided on the inner side of the through hole.

[0006] Preferably, the connecting mechanism includes a connecting post, the top of which has a second insertion hole, a screw is provided on the inner side of the connecting post, and a plug is fixedly connected to the bottom of the screw.

[0007] Preferably, the lower inner end of the connecting column is provided with a threaded hole.

[0008] Preferably, the bottom of the base plate is provided with casters.

[0009] Preferably, the placement mechanism includes a placement plate, a fixed clamping block is fixedly connected to the top of the placement plate, and a movable clamping block is provided on the side of the top of the placement plate away from the fixed clamping block.

[0010] Preferably, the bottom of the movable clamping block is fixedly connected to a plug rod, and a round hole is opened on the top of the placement plate on the side below the plug rod.

[0011] Preferably, rubber bases are fixedly connected to both sides of the bottom of the placement plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a loading mechanism. The base plate can slide in two slide rails. The connecting columns of the two freeze-dried plates are aligned vertically. The insert block at the bottom of the upper connecting column is inserted into the second insertion hole of the lower connecting column to stack the two freeze-dried plates. The bottom freeze-dried plate is inserted into the first insertion hole of the base plate in the same way to stack multiple freeze-dried plates on the base plate. The base plate is then inserted into the slide rail and a pin is inserted to fix the base plate. When it is necessary to remove the items on the freeze-dried plates, simply pull out the pin and pull out the base plate. The insert block is connected to the screw rod. Rotating the screw rod in the threaded hole can extend and retract the screw rod, thereby increasing the distance between the two freeze-dried plates. When the base plate is pulled out, the moving wheel will support the base plate to prevent the base plate from falling directly to the ground. By connecting multiple freeze-dried plates and then pulling them out with the base plate, it is convenient to load and unload materials. 2. This utility model is equipped with a placement mechanism. When the freeze dryer is started, the machine body will vibrate. Align the freeze drying box with the four clamping blocks and place it on the placement plate from above. Three of the clamping blocks are fixed, and the four clamping blocks fix the freeze drying box from four directions. The movable clamping blocks can be pulled out from the round hole through the insertion rod, so as to easily remove the freeze drying box. The rubber base can increase friction and make the device more stable. By placing the freeze drying box in the middle of the four clamping blocks, the device can be fixed and prevent the device from scratching the outer shell. Attached Figure Description

[0019] By adopting the above technical solution, the insert 264 is connected to the screw 263. Rotating the screw 263 in the threaded hole 265 can extend and retract the screw 263, thereby increasing the distance between the two freeze-drying plates 3.

[0020] Specifically, the bottom of the base plate 22 is equipped with casters 25.

[0021] By adopting the above technical solution, when the base plate 22 is pulled out, the moving wheel 25 will support the base plate 22 to prevent the base plate 22 from falling directly to the ground.

[0022] In this embodiment, the connecting post 261 is fixed inside the through hole 6. Items to be processed can be placed on the freeze-drying plate 3. The base plate 22 can slide within the two slide rails 21. The connecting posts 261 of the two freeze-drying plates 3 are aligned vertically. The insert block 264 at the bottom of the upper connecting post 261 is inserted into the second insert hole 262 of the lower connecting post 261, thus stacking the two freeze-drying plates 3 together. The bottom freeze-drying plate 3 is then inserted into the first insert hole 23 of the base plate 22 in the same manner, allowing multiple freeze-drying plates 3 to be stacked on the base plate 22.

The base plate 22 and multiple freeze-drying plates 3 can be removed together. The insert block 264 is connected to the screw 263. Rotating the screw 263 in the threaded hole 265 can extend and retract the screw 263, thereby increasing the distance between the two freeze-drying plates 3. When the base plate 22 is pulled out, the moving wheel 25 will support the base plate 22 to prevent the base plate 22 from falling directly to the ground. By connecting multiple freeze-drying plates 3 and then pulling them out with the base plate 22, it is convenient to load and unload materials. Example 2 The difference between this embodiment and embodiment 1 is that the placement mechanism 5 includes a placement plate 51, a fixed clamping block 52 is fixedly connected to the top of the placement plate 51, and a movable clamping block 53 is provided on the side of the top of the placement plate 51 away from the fixed clamping block 52.

[0023] By adopting the above technical solution, the freeze dryer will vibrate when it starts up. The freeze drying box 1 is aligned with the four clamping blocks and placed on the placement plate 51 from above. Three of the clamping blocks are fixed and the four clamping blocks fix the freeze drying box 1 from four directions.

[0024] Specifically, the bottom of the movable clamping block 53 is fixedly connected to the insertion rod 54, and the top of the placement plate 51 has a round hole 55 on the side below the insertion rod 54.
