When the motor 206 drives the stirring pipe 203 to rotate through the rotating rod, the stirring pipe 203 rotates in the ventilation sleeve 207. The exhaust groove 211 in the stirring pipe 203 is in sliding communication with the second pipeline 208 through the first opening. When the first opening of the exhaust groove 211 rotates to the second pipeline 208, the steam in the second pipeline 208 is transmitted to the inside of the exhaust groove 211 of the stirring pipe 203, and then is sprayed into the milk powder through the nozzle 205 communicated on the exhaust groove 211. With the rotation of the stirring pipe 203, the stirring pipe 203 drives the nozzle 205 to rotate, and the steam is transmitted to the inside of the milk powder. The steam generates fine bubbles, so that the steam is uniformly dispersed in the emulsion, and the mixing quality of the steam and the emulsion is improved. The steam sterilization machine 1 transmits steam to the inside of the sterilization barrel 202 through the first pipeline 201, and at the same time, a part of the steam in the first pipeline 201 is transmitted to the inside of the second pipeline 208, which is communicated with the ventilation sleeve 207. When the motor 206 drives the stirring pipe 203 to rotate through the rotating rod, the stirring pipe 203 rotates in the ventilation sleeve 207. The exhaust groove 211 in the stirring pipe 203 is in sliding communication with the second pipeline 208 through the first opening. When the first opening of the exhaust groove 211 rotates to the second pipeline 208, the steam in the second pipeline 208 is transmitted to the inside of the exhaust groove 211 of the stirring pipe 203, and then is sprayed into the milk powder through the nozzle 205 communicated on the exhaust groove 211. With the rotation of the stirring pipe 203, the stirring pipe 203 drives the nozzle 205 to rotate, and the steam is transmitted to the inside of the milk powder. The steam generates fine bubbles, so that the steam is uniformly dispersed in the emulsion, and the mixing quality of the steam and the emulsion is improved. Referring to Figures 6 to 8 As shown in the drawings, the sterilization assembly 2 is provided with an auxiliary assembly 3 on one side. The auxiliary assembly 3 comprises a water tank 301. The second circulating pipe 302 is fixedly installed in the water tank 301. One end of the second circulating pipe 302 is communicated with one end of the first circulating pipe 210. The water pump 303 is fixedly installed in the water tank 301. The output end of the water pump 303 is communicated with the third pipeline 304. One end of the third pipeline 304 is communicated with the first circulating pipe 210. The fourth pipeline 305 is communicated with one side of the third pipeline 304. One end of the fourth pipeline 305 is communicated with one end of the stirring pipe 203. When a part of the steam in the first pipeline 201 is circulated in the first circulating pipe 210, the steam is circulated to the other end of the first circulating pipe 210 and is transmitted to the inside of the second circulating pipe 302. The water tank 301 stores water in the lower layer. The water is supplemented through the feed inlet on one side of the water tank 301. Since the water tank 301 is divided into two layers by a partition plate, the water tank 301 is divided into two layers by the partition plate. The second opening is arranged on the partition plate, and one end of the second circulating pipe 302 is communicated with the upper layer of the water tank 301. Figure 7As shown, at this time, the first circulation pipe 210 is at the lower layer of the water tank 301, and when the steam passes through the lower layer of the water tank 301, the water source cools the water vapor in the first circulation pipe 210, and then liquefies into liquid water. The liquefied liquid water is transmitted to the upper layer of the water tank 301, and then is transmitted to the lower layer of the water tank 301 through the second through port between the upper layer and the lower layer of the water tank 301, and is mixed with the water source in the lower layer to be stored, thereby reducing unnecessary loss of resources. The one-way valve 308 on one side of the second circulation pipe 302 is used to prevent the liquid water cooled and transmitted to the upper layer of the water tank 301 from flowing back to the inside of the second circulation pipe 302 and affecting the normal operation of the second circulation pipe 302. After the milk powder is input into the steam sterilization, the operator starts the water pump 303, and the water pump 303 transmits the water source in the lower layer of the water tank 301 to the inside of the first circulation pipe 210 through the third pipeline 304 again. At this time, the first circulation pipe 210 circulates the water source to cool the milk powder in the sterilization barrel 202, so that a large amount of time is not consumed for heat dissipation in the cooling process of the conventional equipment, and the subsequent processing efficiency of the milk powder is reduced. The water source cooled by the first circulation pipe 210 is also transmitted to the inside of the water tank 301 through the second circulation pipe 302 again, so that the water source can be reused, and the excessive waste of water resources is effectively avoided. The valve 309 at the communication position of the third pipeline 304 and the first pipeline 201 is opened when steam is transmitted, and is closed when the water source is transmitted, so that the water source is not transmitted to the inside of the second pipeline 208 when the water source is circulated through the third pipeline 304, and the operation of the second pipeline 208 is not affected. When the milk powder is sterilized and cooled, the operator opens the valve 309 on the discharge port of the sterilization barrel 202, and the milk powder in the sterilization barrel 202 is discharged. After the discharge is completed, the operator opens the valve 309 on the fourth pipeline 305, and the water pump 303 transmits the water source in the third pipeline 304, part of which is transmitted to the fourth pipeline 305. Since the fourth pipeline 305 is connected to one end of the stirring pipe 203 through the connector 306, when the stirring pipe 203 rotates, the connector 306 slides on the sliding groove of the stirring pipe 203 through the convex disc 307, so that the connector 306 does not affect the rotation of the stirring pipe 203. Because the third opening is arranged on one side of the drain groove 212 in the stirring pipe 203, the fourth pipeline 305 transmits the water source to the drain groove 212 through the third opening of the drain groove 212. At this time, the water source in the drain groove 212 is transmitted to the spray head 205 connected to the drain groove 212, and then the operator starts the motor 206 again. The motor 206 drives the spray head 205 to rotate through the stirring pipe 203, so as to clean the inner wall of the sterilization barrel 202. When the milk powder in the sterilization barrel 202 is discharged, the residual milk powder adheres to the inner wall of the sterilization barrel 202, which may cause contamination risk when the next group of milk powder to be treated is sterilized in the sterilization barrel 202, thereby adversely affecting the sterilization efficiency of the milk powder.
