As an embodiment of the present invention, a first blade 21 is fixedly connected to both the front and rear sides of the scraper 20; the cutting surface of the first blade 21 is an inclined surface; the left side and the right side of the scraper 20 are fixedly connected with second blades 22; the cutting surface of the second blade 22 is a bevel; during operation, scraper blade 20 scrapes selenized compound L-amino acid in the scraping process, and the mutual stacking between the selenized compound L-amino acid can cause the hindrance to scraper blade 20, and through setting up first blade 21 and second blade 22, the scraping cutting ability is increased to the rotatory scraping direction of scraper blade 20, so that selenized compound L-amino acid can be cleared up fast, and is rolled under the effect of inclined plane and pushed, and the scraping resistance is reduced.

As an embodiment of the present invention, a support rod 23 is rotatably connected to the right side of the mounting plate 2; two sides of the bottom end of the right side of the support table 1 are fixedly connected with support slide rails 24; one end of the support rod 23, which is far away from the mounting plate 2, is rotatably connected with a support sliding block 25; the supporting slide block 25 is connected on the inner wall of the supporting slide rail 24 in a sliding manner; the during operation, when dry shell 3 overturns and unloads, amino acid can collect the upset end to dry shell 3, make the focus of dry shell 3 remove to the tail end of dry shell 3, cause the upset of whole brace table 1 easily, through setting up bracing piece 23, supporting slide 25 and support slide rail 24, at the in-process of dry shell 3 upset, dry shell 3 promotes bracing piece 23 through mounting panel 2, bracing piece 23 promotes supporting slide 25, can not remove the position until supporting slide 25, through the interact of supporting slide rail 24 and supporting slide 25, make to produce between the tail end of dry shell 3 and the ground and support, avoid causing the upset of brace table 1.

The specific working process is as follows:

when the device works, when the selenium compound L-amino acid is dried, the selenium compound L-amino acid is easy to accumulate in the drying shell 3, so that the stirring range of the stirring blades is limited in the stirring and drying process, only rotary stirring can be carried out, the space between the stirring blades can not be stirred, comprehensive rolling is realized by the driving action between the selenium compound L-amino acids, the stirring is not thorough enough, the selenium compound L-amino acid is not thorough in rolling and can not be fully contacted with hot air, the drying quality is influenced, in the discharging process, the selenium compound L-amino acid can not be thoroughly removed, the amino acid remained in the drying shell 3 for a long time can be mildewed, the next dried amino acid is polluted, in the drying process, the annular heating plate 8 provides a drying heat source for the L-amino acid, the motor drives the stirring shaft 9 to rotate, the stirring shaft 9 synchronously drives the stirring rod 12 on the surface of the mounting ring 11 to stir the amino acid, meanwhile, the electric cylinder 16 is started through the control of the external device, the electric cylinder 16 pushes and pulls the connecting slide block 15 in a reciprocating manner, the connecting slide block 15 acts on the stirring rod 12 in a reciprocating manner through the annular slide rail 14, so that the stirring rod 12 performs transverse reciprocating stirring while performing rotary stirring, the problem that the amino acid between the transverse directions of the stirring rod 12 cannot be stirred is solved, the selenium-enriched compound L-amino acid is stirred more thoroughly, the selenium-enriched compound L-amino acid is dried thoroughly, the drying quality of the selenium-enriched compound L-amino acid is improved, and the synthesis quality of the amino acid is improved; when unloading, two driving motors 6 are synchronously started through an external controller, the driving motors 6 drive the gear 7 to rotate, the gear 7 moves upwards under the meshing action of the outer arc surfaces of the arc-shaped sliding rails 4, the drying shell 3 is synchronously driven to turn over, so that the selenylation compound L-amino acid converges towards the discharge pipe, the situation that the selenylation compound L-amino acid stays at the left end of the inner wall of the drying shell 3 is avoided, the stirring rod 12 is acted on in a reciprocating manner under the action of the electric cylinder 16, the installation ring 11 is synchronously driven to clean the surface of the stirring shaft 9, the amino acid is separated from the stirring shaft 9, the selenylation compound L-amino acid is favorably and thoroughly discharged, the residual selenylation compound L-amino acid is reduced, and the pollution to the next drying work is.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
