[0003] However, existing vacuum freeze dryers have a problem: due to the large number of stainless steel trays, friction occurs between the trays and the plate structure of the discharge device during the automatic discharge process, which may generate insoluble particulate contamination and affect the finished product.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.
[0005] In view of the problems existing in the current automatic discharge vacuum freeze dryer, the present invention is proposed.

[0031] Example 1
[0032] Reference Figure 1-3 This invention discloses an automatic discharge vacuum freeze dryer, including a main body component 1, including a base plate 11, a vertical plate 12 disposed on the upper end of the base plate 11, and a shelf 13 disposed between the two vertical plates 12. Lubrication components 2 are disposed on both sides of the shelf 13. A groove 14 is provided on the inner side of the vertical plate 12, and a drive component 3 is disposed in the groove 14 on the side away from the shelf 13. A connecting magnet 15 is disposed on the outer end of the vertical plate 12 near the shelf 2.
[0033] Specifically, casters 16 are provided around the lower end of the base plate 11, an end plate 17 is provided at the upper end of the upright plate 12, and a freeze dryer tray 18 is provided on the shelf 13.
[0034] Furthermore, the upright plate 12 is provided with three sets, symmetrically distributed in two rows. Through the driving action of the drive component 3, the freeze dryer tray 18 is moved from inside the freeze dryer to the shelf 13 of the device.
[0035] Furthermore, by means of connecting magnet 15, the device is magnetically connected to the freeze dryer, which facilitates the stability of the device's discharge process by means of the force of the drive component 3.
[0036] Furthermore, the omnidirectional wheels 16 facilitate the movement of the device by the staff. When it is not necessary to discharge the product, the device can be moved away. When it is necessary to discharge the product, the device can be connected to the freeze dryer by means of the connecting magnet 15, thereby improving the practicality of the device.
[0037] Furthermore, the end plate 17 helps to prevent dust and impurities from falling into the freeze dryer tray 18 or the inside of the device, thus improving the working environment inside the device.
[0038] Furthermore, the shelf 13 is designed with protrusions on both sides to facilitate the sliding of the freeze dryer tray 18 on the shelf 13, thereby limiting its movement and improving operational stability.
[0039] Operation process: When the operator needs to automatically unload the product inside the freeze dryer, the device is moved to the product outlet side of the freeze dryer. The automatic unloading device is magnetically connected to the freeze dryer by the connecting magnet 15. Then, the drive component 3 is started. Through the driving action of the drive component 3, the freeze dryer tray 18 is pulled out from inside the freeze dryer, realizing the automatic unloading function of the device. As the freeze dryer tray 18 slides on the shelf 13 of the device, the friction between the freeze dryer tray 18 and the shelf 13 is reduced by the setting of the lubrication component 2, thereby reducing the insoluble particles generated by the friction between the two and preventing product contamination.
[0040] Example 2
[0041] Reference Figure 4-7 This embodiment differs from the first embodiment in that: the lubrication assembly 2 includes a first cavity 21 formed inside both sides of the shelf 13, and a fixing box 22 and a compression spring 23 are disposed in the first cavity 21. Multiple fixing boxes 22 and compression springs 23 are linearly arrayed in the first cavity 21.
[0042] Specifically, the fixed box 22 has a second cavity 24 inside, a first through groove 25 at the outer end of the fixed box 22, a first telescopic seat 26 at the upper and lower ends of the second cavity 24, a first telescopic rod 27 inside the first telescopic seat 26, and an angled plate 28 at the outer end of the first telescopic rod 27.
[0043] Specifically, a second through slot 29 is provided on one side of the outer end of the beveled plate 28, a second telescopic seat 241 is provided inside the second cavity 24 near the first telescopic rod 27, a second telescopic rod 242 is provided inside the second telescopic seat 241, a horizontal plate 243 is provided at the lower end of the second telescopic rod 242, and a top plate 244 is provided at the lower end of the horizontal plate 243.
[0044] Specifically, the outer end of the compression spring 23 is provided with an arc-shaped plate 231, the two sides of the arc-shaped plate 231 are provided with arc-shaped edges 232, the inner side of the arc-shaped plate 231 is provided with a guide plate 233, the outer end of the guide plate 233 is provided with a trapezoidal edge 234, and the surface of the trapezoidal edge 234 is provided with a top groove 235.
[0045] Specifically, the guide plate 233, the compression spring 23 and the arc plate 231 are fixedly connected, and the arc plate 231 is slidably connected in the first cavity 21.
[0046] Furthermore, when the arc plate 231 is subjected to pressure from the freeze dryer tray 18 and retracts into the first cavity 21, since the arc plate 231 is fixedly connected to the guide plate 233, it pushes the guide plate 233 to move outward, causing the trapezoidal side 234 at the front end of the guide plate 233 to interact with the angled plate 28. The angled plates 28 on the upper and lower sides are subjected to the force of the trapezoidal side 234, causing the first telescopic rod 27 to retract into the first telescopic seat 26. At the same time, by utilizing the elasticity of the first telescopic rod 27 in the first telescopic seat 26, the trapezoidal side 234 is clamped in the vertical direction, which is beneficial to the stability of the freeze dryer tray 18 during the sliding process on the shelf 13.
[0047] Furthermore, the inclined surface design of the inclined plate 28 allows the inclined surface of the trapezoidal side 234 to contact the inclined surface of the inclined plate 28 when the trapezoidal side 234 moves outward, pushing the inclined plates 28 on both the upper and lower sides to move in the opposite direction, thus providing an operational basis for improving the stability of the freeze dryer tray 18 during the sliding process on the shelf 13.
[0048] Furthermore, as the top groove 235 on the surface of the trapezoidal side 234 moves outward, it engages with the top plate 244 on one side of the inclined plate 28. The top plate 244 is designed with an outer arc structure, which matches the structure of the top groove 235. This allows the trapezoidal side 234 to move outward while the top plates 244 on the upper and lower sides are subjected to force and move in the opposite direction. At the same time, with the help of the second telescopic seat 24 and the second telescopic rod 242, the top plate 244 is engaged in the top groove 235, which limits the trapezoidal side 234 in the vertical direction. Meanwhile, the horizontal movement of the trapezoidal side 234 is unrestricted, which facilitates the resetting of the device's operating structure.
[0049] Furthermore, the arc-shaped edge 232 structure on both sides of the arc plate 231 allows the freeze dryer tray 18 to smoothly enter the space between the arc plates 231 after entering the shelf 13, thereby reducing friction during the process and reducing the generation of unnecessary friction-related substances.
[0050] Furthermore, the arc plate 231 is also designed with an arc structure to reduce the contact area with the freeze dryer tray 18, thereby reducing the substances generated by friction.
[0051] Operation process: When the arc plate 231 is subjected to the pressure of the freeze dryer tray 18, it retracts into the first cavity 21. When the freeze dryer tray 18 is no longer in the shelf 13, the arc plate 231 loses the external force. Through the characteristics of the compression spring 23, it can easily return to its initial position. Similarly, when the arc plate 231 loses its force on the guide plate 233, the trapezoidal side 234 is no longer subjected to the force of the upper and lower inclined plates 28, thus facilitating reset. This ensures that the device achieves the function of lubrication and friction reduction, while improving the stability and practicality of the process.
[0052] The rest of the structure is the same as in Example 1.
[0053] Example 3
[0054] Reference Figure 8 This embodiment differs from the above embodiments in that the drive assembly 3 includes a cylinder 31 disposed in a groove 14 on the side away from the shelf 13, an extension rod 32 disposed in the cylinder 31, and a first magnet 33 disposed on the inward side of the extension rod 32.
[0055] Specifically, a second magnet 34 is provided at the outer end of the freeze dryer tray 18 near the first magnet 33, and the first magnet 33 and the second magnet 34 are magnetically connected.
[0056] Furthermore, the cylinder 31 drives the extension rod 32 to extend or retract, thereby extending or retracting the first magnet 33, which is fixedly connected to the extension rod 32. The extension or retraction of the first magnet 33 provides a prerequisite for the device to automatically discharge the freeze dryer tray 18 inside the freeze dryer.
[0057] Furthermore, by means of the magnetic connection between the first magnet 33 and the second magnet 34, the extension rod 32 drives the freeze dryer tray 18 to move in and out of the freeze dryer during the extension or retraction movement.
[0058] Operation process: After the operator makes the initial magnetic connection between the device and the freeze dryer and the connection is stable, the cylinder 31 is then activated. The cylinder 31 drives the extension rod 32 to extend, so that the first magnet 33 fixedly connected to one side of the extension rod 32 extends outward and contacts the second magnet 34 set at the outer end of the freeze dryer tray 18 inside the freeze dryer, thereby making a secondary magnetic connection between the device and the freeze dryer tray 18. Then, with the help of the retraction movement of the extension rod 32, the freeze dryer tray 18 is pulled into the partition 18 of the device to realize automatic material discharge.
[0059] The rest of the structure is the same as in Example 2.
