The Chinese utility model patent with publication number CN216169987U discloses a drying device for milk powder production, including a drying tower, a side surface of the drying tower near the bottom is fixedly connected to a discharge pipe, a side surface of the drying tower near the top is provided with an atomizing mechanism, and a hot air mechanism is provided at the top of the drying tower. The atomizing nozzle in the utility model is arranged directly below the hot air outlet and the atomizing nozzle faces the hot air outlet upward. The milk powder stock is atomized by the atomizing nozzle and then sprayed upward. The hot air is discharged through the air outlet and merges with the atomized liquid to evaporate the liquid, and the powdered milk powder falls downward. Therefore, the milk powder falling on the atomizing nozzle is easy to block the atomizing nozzle.

[0004] Based on this, it is necessary to design an automatic drying device for milk powder production to avoid the atomizing nozzle being blocked by powdered milk powder. Utility Model Content

DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0017] Embodiment: An automatic drying device for milk powder production, such as Figure 1 and Figure 2As shown, it includes a base 1, a stock liquid storage tank 2, a stock liquid delivery pipe 3, an atomizing nozzle 32, a drying tower 4, an air heater 5 and an air inlet pipe 51. The stock liquid storage tank 2 and the drying tower 4 are installed on the base 1. The stock liquid delivery pipe 3 is connected between the stock liquid storage tank 2 and the drying tower 4. The milk is input into the stock liquid storage tank 2 through the infusion pipe. The end of the stock liquid delivery pipe 3 extending into the drying tower 4 is connected with the atomizing nozzle 32. The air heater 5 installed on the base 1 is connected to the drying tower 4 through the air inlet pipe 51. The air heater 5 is connected to the drying tower 4 through the air inlet pipe 51. The heat engine 5 is used to compress and heat the gas. The air heater 5 heats the gas and then sends it into the drying tower 4 through the air inlet pipe 51. The atomizing nozzle 32 is parallel to the air outlet of the air inlet pipe 51 extending into the drying tower 4 and both are arranged downward. This arrangement allows the gas sent in by the air inlet pipe 51 to move downward after combining with the liquid atomized by the atomizing nozzle 32. The milk powder obtained by combining the milk liquid with the high-temperature and high-pressure gas falls downward, thereby preventing the powdered milk from falling on the atomizing nozzle 32, thereby preventing the atomizing nozzle 32 from being blocked.

[0018] like Figure 2 As shown, an air guide piece 31 is also included. The drying tower 4 is installed with an air guide piece 31 for guiding the hot gas input by the air inlet pipe 51. The air guide piece 31 is connected to the raw liquid delivery pipe 3 and is arranged above the atomizing nozzle 32. The air guide piece 31 is set in a conical shape. The air inlet pipe 51 inputs the heated gas into the drying tower 4, and guides the hot gas through the air guide piece 31, so that the hot gas is fully combined with the liquid atomized by the atomizing nozzle 32 in the drying tower 4, so as to achieve the effect of efficiently evaporating the liquid.

[0019] like Figure 1 and Figure 2 As shown, it also includes a vibration motor 41, a motor 6, a gear 61, a ring gear 7 and a scraper 71. The motor 6 is installed on the outer wall of the drying tower 4, and the gear 61 is connected to the output shaft of the motor 6. The drying tower 4 is rotatably connected with the ring gear 7 meshing with the gear 61, and the ring gear 7 penetrates the drying tower 4. A seal is provided at the connection between the drying tower 4 and the ring gear 7. The ring gear 7 is connected with the scraper 71 that fits the inner wall of the drying tower 4. The gear 61 is driven to rotate by the motor 6, and the gear 61 drives the ring gear 7 to rotate. When the ring gear 7 rotates, it drives the scraper 71 to scrape off the powdered milk powder adhered to the inner wall of the drying tower 4. The vibration motor 41 is installed at the lower part of the drying tower 4. The vibration force generated by the vibration motor 41 shakes off the powdered milk powder adhered to the inner wall of the drying tower 4. The vibration force generated by the vibration motor 41 cooperates with the scraper 71 to lift the scraper 71 to scrape off the powdered milk powder on the inner wall of the drying tower 4, thereby achieving efficient cleaning of the inner wall of the drying tower 4 and avoiding waste of milk powder.

[0020] like Figure 3As shown, it also includes a motor 2 8 and a stirring blade 81. The stirring blade 81 for fully stirring the milk powder stock solution is provided in the stock solution storage tank 2. The motor 2 8 for driving the stirring blade 81 to rotate is installed on the stock solution storage tank 2. The motor 2 8 drives the stirring blade 81 to rotate, thereby realizing the function of fully stirring the milk in the stock solution storage tank 2.

[0021] like Figure 2 As shown, the bottom of the drying tower 4 is connected to a discharge pipe 42 for conveying the dried milk powder to the next process.

[0022] When in use, fresh milk is input into the stock liquid storage tank 2, and the stirring blade 81 is driven by the motor 8 to fully stir the milk in the stock liquid storage tank 2, and then the milk is input into the drying tower 4 through the stock liquid delivery pipe 3, and the milk is atomized through the atomizing nozzle 32 and sprayed out of the drying tower 4; at the same time, the air heater 5 compresses and heats the gas to make it a high-temperature and high-pressure gas, and the high-temperature and high-pressure gas heated and compressed by the air heater 5 is input into the drying tower 4 through the air inlet pipe 51, and the high-temperature and high-pressure gas entering the drying tower 4 is guided by the air guide plate 31 and merged with the milk sprayed out of the atomizing nozzle 32, thereby the milk is dried. The liquid in the liquid evaporates, thereby drying the milk liquid into powdered milk powder; the powdered milk powder falls downward to the bottom of the drying tower 4 and is transported to the next process through the discharge pipe 42; when the motor 6 is powered on, it drives the gear 61 to rotate through its output shaft, and the gear 61 drives the gear ring 7 meshing with it to rotate, and the gear ring 7 drives the scraper 71 to move along the inner wall of the drying tower 4, thereby scraping off the powdered milk powder adhering to the inner wall of the drying tower 4. At the same time, the vibration force generated by the vibration motor 41 accelerates the milk powder on the inner wall of the drying tower 4 to fall off, thereby avoiding the milk powder adhering to the inner wall of the drying tower 4 and causing milk powder waste.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
