[0085] A method for using a drying device for a panax notoginseng freeze-drying production line, using the above-mentioned drying device for a panax notoginseng freeze-drying production line, comprising the following steps:

[0086] Start the cooling mechanism 4, the drying mechanism 5 and the vacuum mechanism 8 to form a low-temperature, vacuum state in the vacuum transfer area 6;

[0087] The two bins close to the cooling mechanism 4 are set as the first feeding bin and the second feeding bin, and the two bins close to the drying mechanism 5 are set as the first discharging bin and the second discharging bin;

[0088] Place the tray containing panax notoginseng raw materials on the feeding structure in the first feeding bin, and at this time the first feeding bin is isolated from the vacuum transfer area 6 by the sealing plate 14;

[0089] After closing the sealing cabin door 3 of the first feeding bin, move the first feeding bin into the vacuum transfer area 6, and at the same time the sealing plate 14 isolates the second feeding bin from the vacuum transfer area 6;

[0090] The feeding structure containing panax notoginseng raw materials is connected and transfers materials through the transfer structure, and at the same time the second feeding bin is filled with materials;

[0091] Switch the positions of the first feeding bin and the second feeding bin to realize continuous feeding;

[0092] Process the panax notoginseng raw materials into panax notoginseng freeze-dried in the vacuum transfer area 6;

[0093] The transfer structure moves the tray containing the notoginseng lyophilizate to the feeding structure in the first discharge bin, at this time the second discharge bin is isolated from the vacuum transfer area 6 by the sealing plate 14;

[0094] The first discharge bin and the second discharge bin switch positions, so that the first discharge bin is isolated from the vacuum transfer area 6 by the sealing plate 14, and the notoginseng lyophilizate is taken out from the first discharge bin;

[0095] At the same time, the feeding structure in the second discharge bin is in communication with the transfer structure;

[0096] Switching the positions of the first discharge bin and the second discharge bin realizes continuous discharge.

[0097] The operation process and effects of the device can be summarized as follows:

[0098] Firstly, before the system starts, the cooling mechanism 4, the drying mechanism 5 and the vacuum mechanism 8 need to be pre-operated to establish a low-temperature and vacuum environment required by the process in the vacuum transfer area 6. When operating, the upper and lower bins in the conveying cabin 2 close to the cooling mechanism 4 side are defined as the first feeding bin and the second feeding bin respectively; similarly, the upper and lower bins close to the drying mechanism 5 side are defined as the first discharge bin and the second discharge bin.

[0099] The specific continuous production process starts from the feeding side: the tray containing notoginseng raw materials is placed on the feeding structure in the first feeding bin which has been isolated from the vacuum transfer area 6, and then the sealing cabin door 3 of the bin is closed. Then, the sealing plate 14 is driven to move, so that the first feeding bin carrying the materials enters the vacuum transfer area 6 as a whole, at the same time, the sealing plate 14 isolates the second feeding bin synchronously to prevent external air from entering. After entering the vacuum area, the feeding structure successfully docks with the internal transfer structure, and the tray is transferred to the transfer structure to start moving to the discharge side. In this process, the operator can complete the loading of the next batch of raw materials in the isolated second feeding bin, preparing for continuous feeding. By reciprocating the sealing plate 14 to switch the positions and states of the first feeding bin and the second feeding bin, the intermittent input of raw materials and the continuous conveying in the system can be realized without damaging the environment of the vacuum core area.

[0100] The materials are carried by the transfer structure in the vacuum transfer area 6, and in the process of moving from the end close to the cooling mechanism 4 to the end close to the drying mechanism 5, they complete the processes of quick freezing, sublimation drying and other processes in sequence, and finally are converted into notoginseng lyophilizate products.

[0101] At the discharge side, the dried S. Sancheng is transferred from the transfer structure to the feeding structure in the first discharge bin, while the second discharge bin is isolated by the sealing plate 14. Then, by moving the sealing plate 14 to switch the state of the two discharge bins, the first discharge bin loaded with the finished product is isolated from the vacuum area to open the sealed hatch 3 for safe removal of the product; at the same time, the second discharge bin enters the vacuum area to prepare to receive the next batch of finished products. In this way, the continuous and efficient output of Sancheng freeze-drying is realized, and the stability and isolation of the core process section during the entire production process are ensured.
