Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5This utility model provides a technical solution: a spray drying device for goat milk powder, including a base 1, a screening box 2 fixedly connected to the top of the base 1, a first conveying pipe 4 fixedly connected to the top of the screening box 2, a drying chamber 3 fixedly connected to the top of the first conveying pipe 4, the first conveying pipe 4 communicating with the interior of the screening box 2 and the drying chamber 3, a connecting cylinder 17 fixedly connected to the interior of the drying chamber 3, the connecting cylinder 17 separating the interior space of the drying chamber 3, and a fixed connection between the drying chamber 3 and the connecting cylinder 17. A spiral guide plate 16 extends spirally downwards from the top of the drying chamber 3 to the bottom, guiding hot air to flow spirally within the drying tower to ensure more uniform heating of the goat milk. An atomizing nozzle 20 is rotatably connected inside the connecting cylinder 17. The atomizing nozzle 20 atomizes the goat milk into uniform, fine droplets. A rotating shaft 19 is fixedly connected to the bottom of the atomizing nozzle 20. The atomizing nozzle 20 includes a mounting base and a nozzle. The rotating shaft 19 is fixedly connected to the center of the bottom of the mounting base. The atomizing nozzle 20 rotates... The rotating shaft 19 rotates, and scrapers 18 are symmetrically fixed to the outside of the rotating shaft 19 via a fixing plate. The rotation of the rotating shaft 19 causes the scrapers 18 to rotate. An air heater 7 is fixedly connected to the top of the drying chamber 3 and above the spiral guide plate 16. One end of the air heater 7 extends through one side of the drying chamber 3 into the drying chamber 3. The air heater 7 heats the air entering the drying chamber 3. A sieve plate 25 is fixedly connected inside the screening box 2 to screen the spray-dried goat milk powder. One end of the sieve plate 25 is fixedly connected to a connecting plate 26 through one side of the screening box 2. A vibrator 27 is installed on the side of the connecting plate 26 away from the sieve plate 25. When the vibrator 27 is turned on, it causes the sieve plate 25 to vibrate through the spiral guide plate 16 to prevent goat milk powder from accumulating on the surface of the sieve plate 25. An air inlet pipe 6 is fixedly connected to the top of the air heater 7. One end of the air inlet pipe 6 is connected to an air pump to draw gas into the air inlet pipe 6. An exhaust pipe 8 is fixedly connected to one side of the drying chamber 3 to discharge excess gas from the drying chamber 3.

[0026] Furthermore, a second conveying pipe 11 is fixedly connected to the side of the screening box 2 away from the connecting plate 26, and a goat milk storage tank 13 is fixedly connected to the bottom of the base 1. The end of the second conveying pipe 11 away from the screening box 2 passes through the bottom of the base 1 and extends into the interior of the goat milk storage tank 13. The unqualified goat milk powder screened out by the sieve plate 25 enters the goat milk storage tank 13 through the second conveying pipe 11 for drying again.

[0027] Furthermore, a water pump 12 is fixedly connected to one end of the top of the base 1. One end of the water pump 12 extends through the bottom of the base 1 into the goat milk storage tank 13, and the water pump 12 draws goat milk from the goat milk storage tank 13.

[0028] Furthermore, a first connecting pipe 10 is fixedly connected to the end of the water pump 12 away from the goat milk storage tank 13, and the water pump 12 delivers the extracted goat milk into the first connecting pipe 10.

[0029] Furthermore, the drying chamber 3 is fixedly connected to a mounting bracket 5, and a rotary joint 9 is installed on the top of the mounting bracket 5. The end of the first connecting pipe 10 away from the water pump 12 is connected to the rotary joint 9, and the first connecting pipe 10 delivers the pumped sheep milk into the rotary joint 9.

[0030] Furthermore, a third connecting pipe 21 is fixedly connected to the top of the atomizing nozzle 20. The sheep milk in the third connecting pipe 21 enters the atomizing nozzle 20, and the atomizing nozzle 20 atomizes and sprays the sheep milk. The end of the third connecting pipe 21 away from the atomizing nozzle 20 passes through the top of the fixing frame 5 and is connected to the rotary joint 9. The sheep milk in the rotary joint 9 enters the third connecting pipe 21, and under the action of the rotary joint 9, the rotation of the third connecting pipe 21 will not cause the first connecting pipe 10 to rotate.

[0031] Furthermore, a first bevel gear 22 is fixedly connected to the outside of the third connecting pipe 21. The rotation of the first bevel gear 22 causes the third connecting pipe 21 to rotate. A second bevel gear 23 is meshed with one side of the first bevel gear 22. The rotation of the second bevel gear 23 causes the first bevel gear 22 to rotate.

[0032] Furthermore, a motor 15 is fixedly connected to one side of the fixed frame 5. The output end of the motor 15 passes through one side of the fixed frame 5 and is fixedly connected to the center of one side of the second bevel gear 23. When the motor 15 is turned on, it drives the second bevel gear 23 to rotate.

[0033] Furthermore, the screening box 2 is detachably connected to a goat milk powder collection box 24 to collect qualified goat milk powder for subsequent processing. The bottom of the base 1 is fixedly connected to a support leg 14 to better place the entire device on the ground.

[0034] In use, connect one end of the air pump to the air inlet pipe 6, turn on the air heater 7 to heat the gas in the air inlet pipe 6, and simultaneously turn on the water pump 12 and the vibrator 27. The water pump 12 draws sheep milk from the sheep milk storage tank 13. The sheep milk enters the atomizing nozzle 20 through the first connecting pipe 10 and the third connecting pipe 21. The atomizing nozzle 20 atomizes the sheep milk into fine droplets. The hot air in the air inlet pipe 6 enters the drying chamber 3 and moves along the spiral guide plate 16, guiding the hot air to flow in a spiral shape in the drying tower, making the heating of the connecting cylinder 17 more uniform. When the sheep milk droplets come into contact with the hot air, the moisture on the surface of the droplets quickly absorbs the heat of the hot air and changes from liquid to gas in the form of evaporation. The droplets then detach from the droplets and enter the hot air flow. As the moisture continues to evaporate, the dry matter concentration in the droplets continuously increases. When the moisture evaporates to a certain extent, the dry matter begins to aggregate and solidify, forming solid goat milk powder particles. The goat milk powder enters the screening box 2 through the first conveying pipe 4. The vibrator 27 is turned on, and the sieve plate 25 vibrates through the connecting plate 26. The sieve plate 25 vibrates and screens the goat milk powder. Goat milk powder particles of the qualified size fall into the goat milk powder collection box 24, while unqualified particles are screened out and return to the goat milk storage tank 13 through the second conveying pipe 11. After mixing and melting with the goat milk liquid, the particles are pumped back to the drying box 3 through the water pump 12 for drying. After the goat milk in the goat milk storage tank 13 is used up, clean water can be injected into the goat milk storage tank 13. The water pump 12 and the rotating shaft 19 are turned on, and the water pump 12 pumps the water in the goat milk storage tank 13 to... In the atomizing nozzle 20 of the drying chamber 3, after the rotating shaft 19 is opened, it drives the first bevel gear 22 to rotate through the second bevel gear 23. The first bevel gear 22 drives the third connecting pipe 21 to rotate. The third connecting pipe 21 drives the atomizing nozzle 20 and the rotating shaft 19 to rotate. The atomizing nozzle 20 sprays water while rotating, so that the sprayed water can be better sprayed onto the inner wall surface of the connecting cylinder 17. When the rotating shaft 19 rotates, it drives the scraper 18 to rotate. The water mist sprayed by the atomizing nozzle 20 cleans the inner wall surface of the scraper 18. The goat milk powder collection box 24 in the screening box 2 adopts a detachable connection method. When cleaning is required, the operator can easily remove it to thoroughly clean the goat milk powder remaining in the goat milk powder collection box 24.
