Then, under certain vacuum conditions, the water or solvent therein is sublimated directly from the solid state in the form of steam. The volume of the substance after drying is the same as that before drying, but it is loose and porous and has good rehydration properties.

[0027] The storage table 2 is arranged on one side of the freeze dryer 1, and has a mechanical clamp 21 on the storage table 2, which is used to place materials on the storage rack 12; it should be pointed out here that in the embodiment of the present invention, the mechanical clamp 21 on the storage table 2 has a variety of structural forms, which are used to grab the material tray 123, and technical personnel in this field can choose according to needs.

[0028] The freeze dryer 1 also has a guide bracket 14 adapted to the freeze drying chamber 11, the chamber door 13 has a roller arranged toward the guide bracket 14, and also includes a first driving member 15 for driving the chamber door 13 to rise and fall, the guide bracket 14 has an inclined guide groove 141, the guide groove 141 is inclined toward the freeze drying chamber 11, and when the first driving member 15 drives the roller on the chamber door 13 to snap into the guide groove 141, the sealing surface of the chamber door 13 is pressed toward the freeze drying chamber 11. In an embodiment of the present invention, the first driving member 15 has various forms, such as a cylinder or an oil cylinder, such as Figure 3 and Figure 4 As shown in , the hatch 13 can be lifted by steel wire, and the hatch 13 can be opened by its own weight. By setting the guide groove 141, when the hatch 13 rises, the roller is inserted into the guide groove 141, and the hatch 13 is pressed toward the freeze-drying cabin 11 under the action of the guide groove 141 to achieve sealing. In addition, in the embodiment of the present invention, the first driving member 15 can be set as an oil cylinder, and a detection sensor can be installed on the oil cylinder to detect the extension and retraction of the oil cylinder, corresponding to the opening and closing of the hatch 13. The hatch 13 is pulled by a steel wire rope to drive the hatch 13 to move up and down. One end of the steel wire rope is fixed to the lifting ring above the hatch 13, and the other end is fixed to the output shaft of the oil cylinder.

[0029] In the above embodiment, by means of the guide bracket 14 provided on the freeze-drying chamber 11, and the guide groove 141 provided on the guide bracket 14 and inclined toward the freeze-drying chamber 11, after the chamber door 13 rises and enters into the guide groove 141, the chamber door 13 is pressed toward the freeze-drying chamber 11 under the action of the guide groove 141, thereby achieving sealing. Compared with manual opening and closing in the prior art, the convenience and reliability of opening and closing are improved.

[0030] Alternatively, if Figure 5 As shown in the figure, the rack 12 has a slide rail 121 and a placement table 122 which can slide relatively on the slide rail 121, the placement table 122 is used to place the material tray 123, and the placement table 122 has a positioning groove 124 adapted to the material tray 123. In the embodiment of the present invention, the placement table 122 is pulled out or pushed back in the form of a drawer, and the shape of the positioning groove 124 is adapted to the shape of the material tray 123 to accommodate the offset of the position of the material tray 123.

[0031] Alternatively, if Figure 6 and Figure 7As shown in , in an embodiment of the present invention, the front end of the placement table 122 has a flange 1221 perpendicular to the surface of the placement table 122, and the bottom of the front end of the mechanical gripper 21 has a hook groove 211 adapted to the flange 1221. When the placement table 122 is pulled out or retracted, the mechanical gripper 21 is first moved to a position where the hook groove 211 corresponds to the flange 1221, so that the hook groove 211 on the mechanical gripper 21 is stuck with the flange 1221, and then the placement table 122 is pulled out or retracted by moving the mechanical gripper 21. After the placement table 122 is pulled out, the material tray 123 is grasped or put back by the gripper.

[0032] Optionally, please continue to refer to Figure 1 In the embodiment of the present invention, in order to further realize the diversity of drying, a microwave dryer 3 is also included, which is arranged on one side of the freeze dryer 1 and is arranged at a 90-degree angle with the freeze dryer 1; the microwave dryer 3 has a rotating storage platform 31 and a microwave drying box 32, and the bottom of the microwave drying box 32 has a lifting door 33 that can be lifted and lowered. For details, please refer to Fig. 9In an embodiment of the present invention, the lifting door 33 includes a door body 331, a sealing ring 332 arranged on the door body 331, and a lifting driving member 333 for driving the door body 331 to lift and lower. By setting the lifting driving member 333, the lifting door 33 can be automatically closed and opened. By setting the sealing ring 332, the lifting driving member 333 drives the door body 331 to rise and abut against the bottom of the microwave drying box 32 to achieve sealing, and then the drying process can be started. In an embodiment of the present invention, a microwave generator, a pressure sensor and a temperature sensor are arranged on the microwave drying box 32, and the microwave generator is connected to the vacuum pump, and the sample to be dried enters the box. At this time, the vacuum pump is started to extract the air inside the box to form a negative pressure state inside. Under the negative pressure state, the evaporation temperature of the liquid decreases, and the sample can be quickly dried at a relatively low temperature. After the negative pressure state is formed, the pressure sensor detects that the pressure meets the requirements and starts the microwave generator. The microwave in the box can increase the temperature of the sample. The temperature sensor can detect the sample temperature in real time, and perform feedback adjustment to continuously heat and dry the sample within a certain temperature. After drying is completed, the vacuum pump stops working, and the solenoid valve opens at this time, so that outside air can enter the interior of the box, breaking the negative pressure state in the box. At this time, the door body 331 can be opened to take out the material. In addition, in an embodiment of the present invention, 4 sensors and 1 stepper motor are installed on the bottom plate of the rotating storage platform 31, and a placement window is installed on the front side, which is the manual pick-up and placement point of the material tray 123. A stepper motor is installed in the middle part, and the stepper motor drives the turntable to rotate. There are 12 positions for placing the material tray 123 evenly distributed on the turntable. Capacitive sensor 1 is used to detect whether the material tray 123 is placed, and it can be rotated to the next material tray 123 after it is placed. Capacitive sensor 2 is also used to detect the material tray 123. This sensor can only be grabbed after sensing the material tray 123, and can only be put back into the material tray 123 when it cannot sense the material tray 123. Two induction sheets are installed under the turntable. The cross-sectional view shows the zero position of the turntable, that is, when the induction sheet 2 triggers the photoelectric sensor 1, the tray 123 facing the window is No. 1, and there are 12 trays 123 in total. Each tray 123 has a limit column to position the tray 123. When the stepper motor rotates and the induction sheet 1 triggers the photoelectric sensor 2, the No. 1 tray 123 faces the back side of the turntable. At this time, the mechanical gripper 21 grabs the trays 123 in order starting from No. 1.

[0033] Alternatively, if Fig.10As shown in , the storage table 2 also includes a base 22, a rotating platform 23 arranged on the base 22, a lifting bracket 24 arranged on the rotating platform 23, and a telescopic mechanism 25 arranged on the lifting bracket 24, and the mechanical clamp 21 is arranged on the telescopic mechanism 25.

The telescopic mechanism 25 is slidably connected to the track 242 and connected to the synchronous belt assembly 243. The rotation of the synchronous belt assembly 243 drives the telescopic mechanism 25 to move on the track 242.

[0035] Alternatively, if Fig.12 As shown in FIG. , the rotating platform 23 includes a rotating seat 231 rotatably connected to the base 22, a rotating motor 232 fixed on the rotating seat 231 for driving the rotating seat 231 to rotate, and a lifting motor 233 fixed on the rotating seat 231; please continue to refer to Fig.11 The synchronous belt assembly 243 includes a synchronous belt body 2431, and a synchronous wheel 2331 is provided on the lifting motor 233. The synchronous belt body 2431 is connected to the synchronous wheel 2331.

[0036] Alternatively, if Fig.13 As shown in the figure, the mechanical clamp 21 includes a left clamp arm 212 and a right clamp arm 213 that are arranged opposite to each other, and a clamping drive 214 for driving the two to move closer to or away from each other. In the embodiment of the present invention, in addition to the clamping drive 214, a rotation drive can also be provided to drive the overall axial rotation of the mechanical clamp 21, thereby achieving clamping at different angles. The clamping drive 214 here has a variety of structural forms, for example, the opening and closing of the clamp can be controlled by a cylinder, or the opening and closing of the clamp can be driven by the rotation of a gear, etc.

[0037] Alternatively, if Fig.14 As shown in the figure, the telescopic mechanism 25 includes two parallel and spaced fixed plates 251, a first sliding bracket 252 that is relatively slidably arranged between the two fixed plates 251, and a second sliding bracket 253 arranged inside the first sliding bracket 252; it also includes a telescopic driving member 254 arranged on the first sliding bracket 252 for driving the first sliding bracket 252 to extend or retract relative to the fixed plate 251; it also includes a first idler wheel 255 and a second idler wheel 256 that are respectively arranged at the proximal end and the distal end of the first sliding bracket 252, and the first idler wheel 255 is wrapped with a first synchronous belt 257, one end of the first synchronous belt 257 is fixed to the distal end of the fixed plate 251, and the other end is fixed to the distal end of the second sliding bracket 253; the second idler wheel 256 is wrapped with a second synchronous belt 258, one end of the second synchronous belt 258 is fixed to the proximal end of the fixed plate 251, and the other end is fixed to the proximal end of the second sliding bracket 253. By setting up this structural form, multiple stroke movement can be achieved, that is, when the telescopic driving member 254 drives the first sliding bracket 252 to move, the first idler wheel 255 and the second idler wheel 256 on the first sliding bracket 252 move, such as Fig.14 As shown in the figure, when the first sliding bracket 252 is extended, the first idler wheel 255 drives the second sliding bracket 253 to move outward, and the moving distance of the first synchronous belt 257 is twice the moving distance of the first idler wheel 255, so the moving distance of the second sliding bracket 253 is twice the moving distance of the first sliding bracket 252. Through the setting of this structural form, double contraction driven by the second idler wheel 256 can also be achieved in the reverse direction, and this structural form achieves smaller space occupation.

[0038] Application scenario of an exemplary embodiment: like Figures 1 to 14 As shown, when drying is carried out, the material tray 123 is first placed on the rotating storage platform 31, and then the automatic drying program is started. First, the rotating motor 232 drives the rotating platform 23 to face the microwave dryer 3, and the lifting motor 233 drives the telescopic mechanism 25 to rise and move to the rotating storage platform 31, and the material tray 123 is clamped by the mechanical clamp 21. After clamping the material tray 123, the material tray 123 is placed on the storage rack 12 of the freeze dryer 1 or the lifting door 33 of the microwave dryer 3 as needed, and then the mechanical clamp 21 pushes the storage rack 12 back into the freeze drying chamber 11. After the mechanical clamp 21 is retracted, the control door 13 is closed or the lifting door 33 is closed, and finally the drying program is started to dry the material; after the drying is completed, the material tray 123 that has been dried can be retracted by the reverse operation.
