The first hatch 1302 and the second hatch 1304 can move relative to each other. The limiting rod 1303 can connect and limit the movement.

Then the eighth piston 1513 in the ninth cylinder 1510 moves, thereby driving the fifth piston 1112 to move. Finally, the eighth piston 1513 in the tenth cylinder 1511 moves, thereby driving the first piston 1002 to move.

[0029] The method of use and advantages of this invention: The working process of this vacuum freeze-drying equipment is as follows: like Figures 1 to 10As shown: The first docking track 5 can move under the extension and retraction of the corresponding electric telescopic column 4. The first docking track 5 is used to dock with the second conveying track 7 and the first conveying track 2. The second docking track 6 can move under the extension and retraction of the corresponding electric telescopic column 4. The second docking track 6 is used to dock with two adjacent first conveying tracks 2. During the use of this device, the first docking track 5 or the second docking track 6 can be selected according to the material conveying path. After the material is placed on the material rack 9, the first slider 8 with its own drive roller slides on the first conveying track 2 or the second conveying track 7 to convey the material. Before the material is conveyed into the drying chamber 1101, the electric telescopic rod 1104 extends to drive the pull ring 1105 to move, thereby releasing the rotating hook 13. When the second spring 1305 is pulled back from its stretched state, the second hatch 1304 moves, the rubber ring 1106 leaves the annular groove 1306, and then the second slider 1301 with its own drive roller slides on the third conveying track 12. The support plate 1501 moves together with the second slider 1301, the baffle 14 releases its pressure on the movable rod 1506, the movable rod 1506 and the seventh piston 1504 automatically spring open, all the sixth pistons 1311 move, the movement of the sixth pistons 1311 drives the toothed plate 1312 to move, thereby driving the incomplete gear 1313 to rotate, the hook 1314 rotates away from the pull ring 1105, the first hatch 1302 and the second hatch 1304 are moved away and opened as a whole, and the extrusion plate 1507 moves with the support plate 1504. 01. The pistons move together and sequentially release the pressure on the three movable blocks 1515. The eighth piston 1513 in the eighth cylinder 1509 moves first, followed by the eighth piston 1513 in the ninth cylinder 1510, and finally the eighth piston 1513 in the tenth cylinder 1511. While the eighth piston 1513 in the eighth cylinder 1509 moves, the fourth piston 1110 moves and pushes open the second suspension rail 1108. The second suspension rail 1108 rotates under the support of the fourth piston 1110. While the eighth piston 1513 in the ninth cylinder 1510 moves, the fifth piston 1112 moves. The second suspension rail 1108 rotates to a horizontal state under the tension of the wire rope 1113. The eighth piston 1513 in the tenth cylinder 1511... During the movement of the 13th slide, the first piston 1002, the moving frame 1003, and the third docking track 1004 move downwards. The third docking track 1004 docks the second conveying track 7 with the second suspension track 1108. Two abutments 1008 abut against the second conveying track 7 and the second suspension track 1108 respectively. The second piston 1007 moves upwards along with the abutments 1008. The two third pistons 1011 move under hydraulic pressure. The two pallets 1012 move and support the bottom of the second conveying track 7 and the bottom of the second suspension track 1108 respectively, thus completing a stable docking.
