And the top ends of the two scraping blocks 11 are respectively in contact with the bottom surfaces of the first conveyor belt 3 and the second conveyor belt 4. By making the scraping blocks 11 in contact with the first conveyor belt 3 and the second conveyor belt 4, the function of scraping the possibly adhered medicinal residues on the first conveyor belt 3 and the second conveyor belt 4 can be achieved.

[0026] In this embodiment, water pipes 9 are installed on one side of the freeze dryer body 1 and at the front and rear positions on both sides of the two mounting plates 7. And the end of the water pipe 9 extending into the freeze dryer body 1 is connected with a water spraying port 8. By connecting the water pipe 9 with an external flushing water pipe, making the first conveyor belt 3 and the second conveyor belt 4 rotate, and opening the external water valve, the water flows through the conveyance of the water pipe 9 and is sprayed from the water spraying port 8 onto the rotating first conveyor belt 3 and the second conveyor belt 4, which is convenient for flushing them.

[0027] In this embodiment, cleaning brush cylinders 13 are rotatably installed above the two guiding frames 14 and between the water spraying ports 8 and the scraping blocks 11. And the outer circles of the two cleaning brush cylinders 13 are respectively in contact with the bottom surfaces of the first conveyor belt 3 and the second conveyor belt 4.

[0030] In this embodiment, a discharge port is provided at the front position of the bottom end of the freeze dryer body 1. A discharge baffle 5 that is mutually matched with the discharge port is movably installed through one side of the freeze dryer body 1. The upper position of the front end of the freeze dryer body 1 is transparent. After the freeze-drying process is completed, the discharge baffle 5 can be pulled out to remove the blockage of the discharge port. Then, the first conveyor belt 3 and the second conveyor belt 4 can be started. Since the medicinal materials are placed on them, the freeze-dried medicinal materials can be conveyed to the discharge port through their rotation, and then discharged from the freeze dryer body 1. Moreover, a transparent plate is provided at the front end of the freeze dryer body 1 to facilitate observing the position of the medicinal materials.

[0031] It should be noted that the present utility model is a freeze dryer for preparing dried products of Tibetan medicinal materials. When in use, first, the Tibetan medicinal materials to be freeze-dried can be put into the freeze dryer body 1 through the sealed medicine inlet 2 according to needs. Since the first conveyor belt 3 and the second conveyor belt 4 are rotatably installed in the freeze dryer body 1, and the second conveyor belt 4 is located below the first conveyor belt 3, and at the same time, the side of the first conveyor belt 3 far from the sealed medicine inlet 2 does not contact the freeze dryer body 1. Thus, after the medicinal materials enter, the first conveying motor can be started, and the first conveyor belt 3 can be driven to rotate by the rotation of the driving shaft of the first conveying motor to convey the medicinal materials. And when the medicinal materials are conveyed, they will move slowly and be flattened. Then, the medicinal materials fall onto the second conveyor belt 4 from the end of the first conveyor belt 3 far from the sealed medicine inlet 2. The second conveying motor can be started according to needs, and the second conveyor belt 4 can be driven to rotate by the rotation of the driving shaft of the second conveying motor, so as to convey the fallen medicinal materials again.

[0032] And during the conveying process, the dialing motor can be started according to needs, so that the dialing plate 6 rotates to dial the passing medicinal materials to prevent them from stacking too high on the first conveyor belt 3 or the second conveyor belt 4, which is convenient for improving the evenness of spreading.

[0033] At the same time, since a transparent plate is provided at the front end of the freeze dryer body 1, the position of the medicinal materials can be observed. When the medicinal materials on the second conveyor belt 4 are about to fall to the discharge baffle 5, the second conveying motor and the first conveying motor are turned off. Then, the freeze dryer body 1 can be started according to the existing technology to process the medicinal materials in the freeze dryer body 1.

[0034] And after the freeze-drying process is completed, the discharge baffle 5 can be pulled out to remove the blockage of the discharge port. Then, the first conveyor belt 3 and the second conveyor belt 4 can be started. Since the medicinal materials are placed on them, the freeze-dried medicinal materials can be conveyed to the discharge port through their rotation, and then discharged from the freeze dryer body 1. And when discharging, an external storage device can be placed at the discharge port to collect the discharged medicinal materials.

[0035] Meanwhile, since scraping blocks 11 and water spray nozzles 8 are provided at the bottoms of the first conveyor belt 3 and the second conveyor belt 4, the water delivery pipe 9 can be pre-connected to an external flushing water pipe. Then, following the above steps, the first conveyor belt 3 and the second conveyor belt 4 can be rotated, and the external water valve can be opened to allow water to flow through the water delivery pipe 9 and spray onto the rotating first conveyor belt 3 and second conveyor belt 4 from the water spray nozzles 8, facilitating their flushing. Moreover, the scraping blocks 11 are in contact with the first conveyor belt 3 and the second conveyor belt 4, which can scrape off any potentially adhered medicinal residues on the first conveyor belt 3 and the second conveyor belt 4.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification merely illustrate the principles of the present utility model.
