[0003] In related technologies, some solutions for moisture removal devices for veterinary drug raw plant materials have been disclosed. For example, the authorized patent document with application number CN202320656153.6 discloses a moisture removal device for veterinary drug raw plant materials, which includes a drying chamber. Several drying pipes are arranged in parallel from top to bottom in the drying chamber, and a plant drying area is formed through the area between adjacent rows of drying pipes. Several drying pipes are arranged in parallel in the horizontal direction in each row. A conveying shell is slidably pulled out in the plant drying area. The drying pipes between adjacent rows are respectively provided with nozzles and other components facing the conveying shell.

[0004] In the above-mentioned scheme, the nozzle position is fixed and the position of the plant material in the transport shell remains unchanged.

[0031] In summary: When using this veterinary drug production raw material moisture removal device, granular, flake, or block-shaped raw materials for crushing and tolerating veterinary drugs are fed into the heating section 3 through the feed hopper 4. The drive structure drives the screw feed shaft to rotate, which in turn moves the raw material. During this movement, the blower 16 blows outside air into the heat recovery section 2. The gas in the heat recovery section 2 enters the air heater 8 through the heat recovery exhaust pipe 7, where the air heater 8 heats the air to the required temperature. The air, heated to the required temperature for dehydration of the raw plant materials, is blown into the screw feed shaft through heating pipe 17. The hot air inside the screw feed shaft is discharged between the raw plant materials through exhaust holes, achieving uniform heating. The moisture generated during heating is discharged through moisture discharge pipe 11 by exhaust fan 6. The moisture discharged through moisture discharge pipe 11 enters the inner cavity of the side wall of feed hopper 4. During the movement of the moisture in the inner cavity of the side wall of feed hopper 4, it preheats the raw plant materials in feed hopper 4. The moisture after heat exchange is discharged through exhaust pipe 12. The dried raw plant materials enter the heat recovery section 2 through discharge pipe 18. The raw plant materials move in the heat recovery section 2 under the action of another screw feed shaft. During the movement, the cold air blown in by blower 16 exchanges heat with the raw plant materials, realizing the recovery of heat from the dried raw plant materials. The cooled raw plant materials are discharged through discharge pipe 10, facilitating subsequent processing of the raw plant materials.
