Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0026] like Figure 1 As shown, the powder production equipment of this embodiment includes: a filter device 10, a homogenizer 20, a communication channel 30 and an aeration device 40. The communication channel 30 is arranged between the filter device 10 and the homogenizer 20, and the material flows from the filter device 10 to the homogenizer 20 through the communication channel 30. The aeration device 40 is connected to the communication channel 30 and aerates the material in the communication channel 30.

[0027] According to the technical solution of this embodiment, a connecting channel 30 is provided between the filter device 10 and the homogenizer 20, and the material flows from the filter device 10 to the homogenizer 20 through the connecting channel 30. The gas charging device 40 is connected to the connecting channel 30, and the gas charging device 40 inflates the material in the connecting channel 30. Through the above-mentioned arrangement, the filter device 10 can filter the material. The homogenizer 20 can refine the material so that the material can be mixed more evenly. The connecting channel 30 enables the material to flow from the filter device 10 to the homogenizer 20. The gas charging device 40 can inflate the material in the connecting channel 30, so that the inside of the material can be filled with gas, so that the particle size of the powder produced by the material is larger, and at the same time, the powder also has more air pockets, so that when the powder contacts water, the contact area with water molecules is increased, which is conducive to the rapid dissolution of the powder. Therefore, the technical solution of this embodiment effectively solves the problem that the adjustment effect of the powder particle size is not obvious in the related art.

[0028] It should be noted that the material in this embodiment is concentrated emulsion, and the powder is milk powder. The filtering device 10 is a double filter, and the homogenizing device 20 is a high-pressure homogenizer.

[0029] like Figures 1 to 3As shown, in this embodiment, the inflation device 40 includes an inflation pipe 41 and a nozzle 42, the nozzle 42 is arranged at the gas outlet of the inflation pipe 41, the communication channel 30 includes a first communication pipe 31, the gas outlet of the inflation pipe 41 is connected to the inside of the first communication pipe 31, the first end of the first communication pipe 31 is connected to the filter device 10, and the second end of the first communication pipe 31 is connected to the homogenizing device 20. The gas in the inflation pipe 41 can flow to the inside of the first communication pipe 31 through the nozzle 42, and then the material in the first communication pipe 31 can be inflated. The first communication pipe 31 allows the material to flow from the filter device 10 to the homogenizing device 20.

[0030] Preferably, the powder production equipment also includes a gas source, which can provide gas to the inflation tube 41. The mixed gas provided by the gas source of this embodiment is composed of carbon dioxide and nitrogen, and the proportion of carbon dioxide is adjusted to 20%-100% and the proportion of nitrogen is 0 to 80% using a mixed gas proportioning device. Carbon dioxide can combine with a portion of free water to reduce oxidation and can also play an antibacterial role. Therefore, the total inflation volume and the proportion of carbon dioxide affect the number of final cavitations. Different mixed gas ratios and the addition flow rate of the mixed gas will have different effects on the particle size and have a certain impact on the shelf life of the product. The main function of carbon dioxide is to have more cavitations, and the function of nitrogen is mainly for later preservation. Using the powder production equipment of this embodiment, the powder has the advantages of being more stable during the shelf life, and the oversized particles provide the possibility for subsequent dry mixing of other materials and the possibility for the subsequent production of solid milk powder.

[0031] It should be noted that when the material flow rate is 3 tons / hour, the pressure is 4 bar, the mixed gas flow rate is 0.25 liters / minute, the pressure is 6 bar, and the carbon dioxide accounts for 30%, the particle size of the produced powder is 391.507 microns.

[0032] like Figure 2 As shown, in this embodiment, the inflation device 40 further includes a pressure regulating member 43, which is disposed on the inflation tube 41. The pressure regulating member 43 can adjust the pressure of the gas flowing in the inflation tube 41.

[0033] Preferably, the inflation device 40 further comprises a stop valve, which is arranged between the gas source and the pressure regulating member 43 , so that when inflation is not required, the stop valve can block the inflation tube 41 .

The pressure regulating valve 431 can regulate the pressure of the gas flowing into the first connecting pipe 31 through the inflation pipe 41. The pressure gauge 44 can display the pressure of the gas flowing through the inflation pipe 41, which is convenient for observing the pressure value and also convenient for pressure regulation according to the displayed pressure value.

[0035] like Figure 2 As shown, in this embodiment, the inflation device 40 further includes a flow meter 45 disposed on the inflation tube 41, and the flow meter 45 is disposed between the pressure gauge 44 and the gas outlet of the inflation tube 41. The flow meter 45 can display the flow rate of the gas flowing in the inflation tube 41.

[0036] Preferably, in this embodiment, the flow meter 45 is a glass rotor flow meter.

[0037] like Figure 1 and Figure 3 As shown, in this embodiment, the inflation device 40 further includes a mass flow controller 46 disposed on the inflation tube 41, and the mass flow controller 46 is disposed between the flow meter 45 and the gas outlet of the inflation tube 41. The mass flow controller 46 can accurately measure the flow rate of the gas and can also automatically adjust the gas flow rate so that the flow rate value of the gas can be kept constant.

[0038] Preferably, the gas filling device 40 further includes a pressure stabilizing valve, which is disposed on the gas filling pipe 41 and is located between the mass flow controller and the gas outlet of the gas filling pipe 41. This makes the pressure of the gas in the gas filling pipe 41 more stable, facilitates the stability of the pressure of the gas filling of the material during the powder production process, and makes the particle size variation range of the powder smaller after the powder production is completed.

[0039] It should be noted that the powder production equipment also includes an installation box, and the pressure regulating member 43, the pressure gauge 44, the flow meter 45, the mass flow controller 46 and the pressure regulating valve are all arranged in the installation box. The pressure regulating member 43, the pressure gauge 44, and the flow meter 45 are located between the mass flow controller 46 and the inner wall of the installation box, so that the pressure regulating member 43, the pressure gauge 44, and the flow meter 45 can occupy less space and are convenient for arrangement in the installation box.

[0040] like Figure 1As shown, in this embodiment, the first connecting pipe 31 includes a first pipe section 311 and a second pipe section 312. The first end of the first pipe section 311 is connected to the filter device 10, the second end of the first pipe section 311 is connected to the first end of the second pipe section 312, and the second end of the second pipe section 312 is connected to the homogenizing device 20. There is a preset angle between the first pipe section 311 and the second pipe section 312, and the axis of the nozzle 42 is arranged to coincide with the second pipe section 312. The first pipe section 311 and the second pipe section 312 enable the material to flow from the filter device 10 to the homogenizing device 20. The axis of the nozzle 42 is arranged to coincide with the axis of the second pipe section 312, so that after the gas is ejected through the nozzle 42, the material in the first connecting pipe 31 can be more effectively inflated, and the splashing of the material caused by the impact force generated when the gas is ejected to the inner wall of the second pipe section 312 is reduced.

[0041] Preferably, the nozzle 42 is disposed at the intersection of the first pipe section 311 and the second pipe section 312, and is disposed toward the second pipe section 312, and the direction in which the gas is ejected through the nozzle 42 is the same as the flow direction of the material. The preset angle ranges from 30° to 90°, and specifically, can be 30°, 45°, 60°, 75°, 80° or 90°. In this embodiment, the preset angle is 90°.

[0042] Specifically, the axis of the nozzle 42 and the axis of the second pipe section 312 may also be arranged in parallel.

The second communication pipe 32 and the third communication pipe 33 enable the material to flow from the filter device 10 to the homogenizing device 20. When it is not necessary to inflate the material, the first valve 34 and the second valve 35 can be closed, so that the material can flow directly to the homogenizing device 20 through the second communication pipe 32 and the third communication pipe 33.

[0044] Preferably, the second connecting pipe 32 includes a first extension section, a descending section and a second extension section which are sequentially arranged, the second extension section is connected between the descending section and the first end of the third connecting pipe 33, the second pipe section 312 and the second extension section are at the same height, and the first pipe section 311 is connected between the descending section and the second pipe section 312. A third valve is arranged at the second end of the second connecting pipe 32 and the first end of the third connecting pipe 33. A fourth valve is arranged at a position of the descending section close to the first pipe section 311. When the inflation device is used for inflation, it is possible to prevent the material from flowing back into the second connecting pipe 32 through the third valve and flowing into the second connecting pipe 32 through the fourth valve. The arrangement of the descending section enables the height difference between the outlet of the filtering device 10 and the inlet of the homogenizing device 20 to be compensated under the action of the connecting channel 30.

[0045] like Figures 1 to 3 As shown, in this embodiment, the nozzle 42 includes a plurality of nozzles 42, the inner diameters of the jet ports of the plurality of nozzles 42 are different, and the plurality of nozzles 42 are selectively installed to the gas charging tube 41.

The powder production line with the above-mentioned powder production device also has the above-mentioned advantages.

[0048] Preferably, the powder production line further comprises a concentration tank, a preheater connected to the concentration tank, and a spray gun connected to the homogenizing device 20.
