[0027] The effect achieved by the entire embodiment 1 is that, during use, the operator pulls the pull rope 23 according to the size of the biochemical product. The pull rope 23 drives the two connecting rods 22 to move, which in turn drives the two locking blocks 21 to move. The locking blocks 21 leave the locking slots 24, and the spring 20 is compressed. Then, the operator pushes the fixing base 16 to move and adjusts the distance between each tray 28 according to the size of the biochemical product. When the adjustment is finished, the operator releases the pull rope 23, and the elastic force of the spring 20 pushes the locking blocks 21 into the locking slots 24, thus completing the fixation and improving the application range of the device.

[0028] Example 2, as Figures 1-5 As shown, further, a sliding groove 10 is provided on the inner side wall of the box 1, and a first threaded rod 11 is rotatably installed inside the sliding groove 10. A motor 9 is fixedly installed on the top of the box 1, and the output end of the motor 9 is fixedly connected to one end of the first threaded rod 11. A slider 12 is threadedly connected to the outer wall of the first threaded rod 11.

[0029] Furthermore, a refrigeration unit 8 is fixedly installed on the top of the housing 1. The output end of the refrigeration unit 8 enters the housing 1 and is fixedly installed with a telescopic hose 15. A fixed pipe 13 is fixedly installed at the bottom of the telescopic hose 15. The outer wall of the fixed pipe 13 is fixedly connected to the slider 12. Multiple evenly distributed nozzles 14 are fixedly connected to the outer wall of the fixed pipe 13.

[0030] Furthermore, a connecting plate 26 is fixedly installed on the outer wall of the fixing plate 18, and a connecting groove 27 is provided on the top of the connecting plate 26.

[0031] Furthermore, the outer wall of the fixed base 16 is provided with a guide groove 29, the top surface of the guide groove 29 is provided with a fixed groove 31, the inner wall of the fixed groove 31 is provided with a threaded hole 32, the threaded hole 32 is threadedly connected to a second threaded rod 33, the top of the second threaded rod 33 is fixedly installed with a handle 34, and the bottom of the second threaded rod 33 is movably connected with a fixed block 35.

[0032] Furthermore, an electric heating plate 30 is fixedly installed on the bottom surface inside the fixing base 16.

[0033] Furthermore, a vacuum pump 7 is fixedly installed on the outer wall of the housing 1, and the input end of the vacuum pump 7 penetrates the housing 1 and enters the housing 1.

[0034] Furthermore, a door 4 is hinged to one end of the box body 1, a handle 5 is fixedly installed on the outer wall of the door 4, and an observation window 6 is fixedly installed through the outer wall of the door 4.

[0035] Furthermore, support frames 2 are fixedly installed at the four corners of the bottom of the box 1, and a control panel 3 is provided on the outer wall of the box 1.

[0036] Furthermore, the outer wall of the fixing block 35 fits against the inner wall of the fixing groove 31 to prevent the fixing block 35 from rotating when the second threaded rod 33 rotates.

[0037] The effect achieved by the entire embodiment 2 is that during freeze drying, the operator starts the refrigeration unit 8, and cold air enters the telescopic hose 15 from the output end of the refrigeration unit 8, and then sprays out from the nozzle 14 on the fixed tube 13 to freeze dry the biochemical products. At the same time, the operator starts the motor 9, and the first threaded rod 11 rotates to drive the slider 12 to move along the slide groove 10, which in turn drives the fixed tube 13 to move up and down, so that the contact time between the cold air and the biochemical products on each tray 28 is equal, the freeze drying is more uniform, and the freeze drying efficiency is improved.

[0038] Working principle: During use, the operator pulls the pull rope 23 according to the size of the biochemical product. The pull rope 23 moves the two connecting rods 22, which in turn moves the two locking blocks 21. The locking blocks 21 leave the locking slots 24, and the spring 20 is compressed. Then, the operator pushes the fixed base 16 to move and adjust the distance between each tray 28 according to the size of the biochemical product. When the adjustment is finished, the operator releases the pull rope 23. The elastic force of the spring 20 pushes the locking blocks 21 into the locking slots 24, thus completing the fixation and improving the applicability of the device. During freeze-drying, the operator starts the refrigeration unit 8. Cold air enters the telescopic hose 15 from the output end of the refrigeration unit 8 and is then sprayed out from the nozzle 14 on the fixed tube 13 to freeze-dry the biochemical product. At the same time, the operator starts the motor 9. The first threaded rod 11 rotates, driving the slider 12 to move along the slide groove 10, which in turn moves the fixed tube 13 up and down, so that the contact time between the cold air and the biochemical products on each tray 28 is equal, resulting in more uniform freeze-drying and improving freeze-drying efficiency. Once the temperature inside chamber 1 drops to the required level, the heating plate 30 is activated. The heat generated by the heating plate 30 heats the medicine in tray 28, causing the ice crystals inside the product to sublimate directly into a gaseous state. The vapor emission is controlled by vacuum pump 7, thus enabling the freeze-drying process. Finally, tray 28 is removed to take out the product. If the heating plate 30 malfunctions, the operator rotates handle 34, causing the second threaded rod 33 to rotate and rise along threaded hole 32. The fixing block 35 then leaves connecting groove 27. At this point, the operator can pull out fixing seat 16. When connecting plate 26 leaves guide groove 29, fixing seat 16 can be removed for repair of heating plate 30.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
