DETAILED DESCRIPTION

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figure 1-8 , the present utility model provides a technical solution: a spray drying device for a polyglutamic acid fermentation broth, including an upper connection box 1, an intermediate box 2, a lower connection box 3, a valve 4, a hot air device 5, a hot air pipe 6, a hot air nozzle 7, an atomization device 8, a connection channel 9, a blowing device 10, a connection groove 11, a pump body 12, a lower connection pipe 13, a filtration box 14, an upper connection pipe 15, a silica filter screen 16, a fixing plate 17 and a stopper 18.

[0034] When using the spray drying device for the polyglutamic acid fermentation broth, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the upper connection box 1, the intermediate box 2 and the lower connection box 3 are connected and communicated with each other, and a hot air device 5 is fixedly installed at the upper end of the upper connection box 1. The hot air is conveyed into the hot air pipe 6 through the hot air device 5, and the hot air nozzles 7 are arranged at equal angles at the lower end of the hot air pipe 6. The hot air is conveyed into the upper connection box 1 through the hot air pipe 6 and the hot air nozzles 7. At the same time, the atomization device 8 is fixedly installed at the front end of the upper connection box 1, and the atomization device 8 is connected to the upper connection box 1 through the connection channel 9. The polyglutamic acid fermentation broth in the atomization device 8 is conveyed into the upper connection box 1 through the connection channel 9, so that the atomized droplets of the polyglutamic acid fermentation broth come into contact with the hot air. Moreover, the blowing device 10 installed in the middle of the intermediate box 2 can be started. At this time, the blowing device 10 can suck the atomized droplets of the polyglutamic acid fermentation broth and the hot air in the upper connection box 1 into the lower connection box 3 through the connection groove 11 for sufficient contact and drying, thereby greatly improving the actual drying efficiency. And the dried product can be discharged outwards through the valve 4 installed at the lower end of the lower connection box 3;

[0035] In addition, in combination with Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the hot air after drying in the lower connection box 3 can be pumped by the pump body 12, and the hot air after use can enter the filter box 14 through the hole opened on the block 18 and the lower connection pipe 13. The setting of the block 18 prevents the product from entering the lower connection pipe 13, and the hot air is filtered by the filter box 14, and then transported to the upper connection box 1 through the upper connection pipe 15, so as to facilitate the recycling of the hot air and prevent the loss and waste of heat in the hot air.

[0036] In addition, after use, the fixing plate 17 can be flipped over, and the fixing plate 17 can be rotated on the filter box 14. The torsion spring at the connection between the fixing plate 17 and the filter box 14 is elastically deformed, so that the fixing plate 17 and the silica filter 16 are separated, thereby loosening the limit between the silica filter 16 and the filter box 14, and then the silica filter 16 is pulled outward to directly pull the silica filter 16 out of the filter box 14, so that the silica filter 16 can be disassembled, cleaned and replaced, which is very convenient to use. At the same time, the contact positions between the parts in this solution are all provided with sealing rings or sealing gaskets to ensure the air tightness of the entire device and prevent leakage.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
