AI Technical Summary
In existing feed drying equipment, wet feed tends to clump together during the drying process, resulting in poor drying effect and poor feeding quality.
The system uses a stirring shaft and stirring rod in conjunction with a rotating fan and heating wire to dry and disperse feed through stirring and hot air. At the same time, it uses sieve holes and baffles to collect completely dried feed, while the feed that is not completely dried continues to be stirred and dispersed.
This process achieves thorough loosening and efficient drying of the feed, thus improving feeding quality.

Detailed Implementation
[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0019] like Figs. 1-3 As shown, this utility model provides a technical solution: a drying device for fish, shrimp and crab feed production, including a drying cylinder 1, a motor protective shell 2 fixedly connected to the top of the drying cylinder 1, a servo motor 3 fixedly connected inside the motor protective shell 2, a stirring shaft 4 fixedly connected to the output end of the servo motor 3 through the drying cylinder 1, the top end of the stirring shaft 4 being rotatably connected to the drying cylinder 1 via a bearing, and a plurality of stirring rods 5 fixedly connected to the outer arc surface of the stirring shaft 4 inside the drying cylinder 1. Through the setting of the stirring rods 5, the servo motor 3 drives the stirring shaft 4 to rotate, and when the stirring shaft 4 rotates, it drives the stirring rods 5 to stir and disperse the feed.
[0020] The top of the drying cylinder 1 has mounting holes 19 on both sides of the motor protective shell 2. A ventilation plate 11 is fixedly connected in the mounting holes 19. A wind box 8 is fixedly connected to the top of the drying cylinder 1 at the position corresponding to the ventilation plate 11. A rotary fan 10 is fixedly connected in the wind box 8. By starting the rotary fan 10, the two rotary fans 10 rotate to form an air duct, so that the feed can be fully mixed with the hot air, and the feed can be dried more efficiently.
[0021] An electric heating wire 9 is fixedly connected to the top wall of the air box 8, and a feed inlet 20 is fixedly connected to the top of one side of the drying cylinder 1. With the setting of the feed inlet 20, the feed inlet 20 can not only facilitate the feed to enter the drying cylinder 1, but also allow the feed inlet 20 to exhaust air when the rotating fan 10 blows air into the drying cylinder 1, so that air circulates inside the drying cylinder 1.
[0022] Several air outlets 12 are provided on both sides of the air box 8. A base plate 6 is fixedly connected to the bottom of the drying cylinder 1. The bottom end of the stirring shaft 4 is rotatably connected to the base plate 6 through a bearing. Several screening holes 7 are provided on the top of the base plate 6. A base 13 is fixedly connected to the bottom of the drying cylinder 1. With the setting of the screening holes 7, the dispersed feed can be screened through the screening holes 7, while the undispersed feed will remain in the drying cylinder 1 and be dispersed again.
[0023] A collection box 14 is slidably connected inside the base 13. A sliding groove 16 is provided on the top of the collection box 14. A baffle plate 17 is slidably connected inside the sliding groove 16. The position of the baffle plate 17 corresponds to the bottom plate 6. By setting the baffle plate 17, the baffle plate 17 blocks the screen hole 7 to prevent the feed from falling into the collection box 14 through the screen hole 7 during drying, thus resulting in low drying efficiency.
[0024] A pull block 18 is fixedly connected to one side of the baffle plate 17, and a handle 15 is fixedly connected to one side of the collection box 14. With the pull block 18 and the handle 15, the baffle plate 17 is moved by the pull block 18, and the collection box 14 is moved by the handle 15, so that the corresponding object can be easily pulled out and used.
[0025] The working principle of this utility model is as follows: First, the feed is put into the drying cylinder 1 through the feed inlet 20. At this time, the heating wire 9 can be activated. When the heating wire 9 generates heat, the rotating fan 10 can be activated to rotate. The rotation of the two rotating fans 10 forms an air duct, which fully contacts the heat with the feed to dry the feed. At the same time, the servo motor 3 can be activated, which drives the stirring shaft 4 and the stirring rod 5 to rotate and stir the feed to disperse it. After drying is completed, the pull block 18 can be pulled to drive the baffle plate 17 to pull out the top of the collection box 14. At this time, the dried and dispersed feed will be discharged into the collection box 14 through the screen hole 7. The feed that is not completely dispersed will remain in the drying cylinder 1 and continue to be dispersed by the stirring rod 5. When the dried and dispersed feed falls into the collection box 14, the collection box 14 can be pulled out by the handle 15 to discharge the feed.
