[0026] As shown in Figure 1 and Figure 2 , the utility model embodiment provides a dairy product evaporation concentration system, comprising: evaporation concentration equipment 1, steam jet pump 2 and condensate pump 3;
[0027] Evaporation concentration equipment 1 includes falling film evaporator 11 and separator 12, and falling film evaporator 11 includes evaporation chamber 111 and concentration chamber 112 in communication, and concentration chamber 112 and separator 12 are communicated, and separator 12 is used to condense the vaporized water separated out in the dairy product;

[0030] It can be understood that evaporation concentration equipment 1 has a feeding end and a discharging end, and the feeding end and evaporation chamber 111 are communicated, and the discharging end and concentration chamber 112 are communicated. The dairy product can enter evaporation chamber 111 from the feeding end, and the dairy product is evaporated and concentrated in evaporation chamber 111, and most of the water in the dairy product is gradually heated and vaporized in the process of entering concentration chamber 112 after the evaporated and concentrated treatment, the vaporized water enters separator 12 and condenses into condensate water in separator 12, and the concentrated dairy product is collected in concentration chamber 112 and can be discharged from the discharging end.
[0031] In the process of evaporative concentration of the dairy product, high-pressure steam generated by a high-pressure steam source enters the steam ejector pump 2 along the steam input pipeline 110, the steam ejector pump 2 further pressurizes the high-pressure steam, and the pressurized high-pressure steam reaches the evaporation chamber 111 through the steam output pipeline and exchanges heat with the dairy product in the evaporation chamber 111 to realize the evaporative concentration of the dairy product.
[0032] The pressure of the high-pressure steam is usually higher than the atmospheric pressure, for example, the pressure of the high-pressure steam is 3-5 bar, and the corresponding temperature is about 134-152℃.
[0033] Due to the high flow rate of the high-pressure steam in the steam ejector pump 2, part of the gas in the concentration chamber 112 can be discharged into the steam ejector pump 2 under the action of the pressure difference to improve the acidity of the dairy product in the concentration chamber 112.
[0034] The embodiment is configured with the evaporative concentration device 1, the steam ejector pump 2 and the condensate pump 3, the high-pressure steam ejected by the steam ejector pump 2 is used to heat the evaporation chamber 111 of the evaporative concentration device 1, the dairy product flowing through the evaporation chamber 111 can be evaporatively concentrated, most of the water in the dairy product is gradually heated and vaporized during the flow from the evaporation chamber 111 to the concentration chamber 112, and forms condensate water in the separator 12, under the pumping of the condensate pump 3, the condensate water in the separator 12 can reach the corresponding first interlayer structure of the steam ejector pump 2 along the first pipeline 10 and the second pipeline 20, the condensate water in the first interlayer structure is returned to the condensate pump 3 along the third pipeline 30 after heat exchange, and circulates in this way. As can be seen from the above, the shell wall of the steam ejector pump 2 is cooled by the condensate water separated during the evaporative concentration of the dairy product, the condensate water is reused, the system energy consumption is low, the problem of high-temperature paste dirt during the evaporative concentration of the dairy product is effectively solved, and the product quality is ensured.
[0035] In some embodiments, as shown in Figs. Figure 1 and Figure 2 The evaporation chamber 111 is communicated with the separator 12 through the drainage pipeline 120, and the drainage pipeline 120 is used to guide the condensate water condensed by the high-pressure steam in the evaporation chamber 111 into the separator 12.
[0036] It can be understood that two flow channels independent of each other are formed in the evaporation chamber 111, the two flow channels are respectively used for the flow of the dairy product and the high-pressure steam, and heat exchange between the dairy product and the high-pressure steam can be realized, part of the high-pressure steam is condensed into condensate water after completing the heat exchange with the dairy product, and the other part can be discharged from the exhaust port of the evaporation chamber 111.
[0037] The embodiment utilizes the drain pipeline 120 to guide the condensed water condensed by the high-pressure steam in the evaporation chamber 111 to the separator 12, the separator 12 can further cool the condensed water, and the condensed water in the separator 12 can be pumped to the steam jet pump 2 by the condensed water pump 3, so as to cool the shell wall of the steam jet pump 2.

[0041] It can be understood that, since the condensation chamber 112 and the separator 12 communicate, the vacuum pump 4 is used to vacuumize the separator 12, so that the falling film evaporator 11 and the separator 12 are in a low-pressure or negative-pressure state, which is beneficial to reduce the boiling point of water, promote the separation of water in the dairy product during the flow of the dairy product from the evaporation chamber 111 to the condensation chamber 112, enhance the condensation effect of the dairy product, and improve the water separation amount. The vaporized water separated out can automatically flow from the condensation chamber 112 to the separator 12 and be condensed into condensed water in the separator 12.
[0042] In some embodiments, as shown in Figure 1 In order to ensure the condensation effect of the separator 12 on water, the shell wall of the separator 12 has a second sandwich structure, one end of the second sandwich structure is configured to communicate with the cooling water input pipe 70, and the other end is configured to communicate with the cooling water return pipe 80.
[0043] Further, the ends of the cooling water input pipe 70 and the cooling water return pipe 80 away from the separator 12 are configured to communicate with the water tank, and the cooling water input pipe 70 is provided with a circulating water pump. Under the pumping of the circulating water pump, the cooling water can circulate between the water tank and the second sandwich structure, so as to effectively control the temperature in the separator 12 and promote the condensation of water in the separator 12.

[0046] In some embodiments, as shown in Figure 2 As shown, in order to facilitate the evaporation and concentration of dairy products by high-pressure steam, the evaporation chamber 111 is provided with a heat exchange pipe bundle 1110, which includes a plurality of heat exchange pipes arranged side by side; each heat exchange pipe is used to pass in dairy products, and a third interlayer structure is formed between different heat exchange pipes and between the heat exchange pipes and the inner wall of the evaporation chamber 111, and the steam jet pump 2 and the third interlayer structure are communicated to pass high-pressure steam into the third interlayer structure.

[0049] It can be understood that when the evaporation and concentration device 1 normally evaporates and concentrates dairy products, the corresponding valve on the sixth pipe 60 is in a closed state, and under the pumping of the material pump 5, the dairy products concentrated by the evaporation and concentration device 1 are conveyed to the feeding device along the discharge pipe 100.
[0050] When it is necessary to clean the evaporation and concentration device 1, the corresponding valve on the sixth pipe 60 is in an open state, and since the evaporation and concentration device 1 forms a closed cleaning loop with the feeding device through the discharge pipe 100 and the sixth pipe 60, under the pumping of the material pump 5, the cleaning liquid is conveyed to the feeding device along the discharge pipe 100, and the cleaning liquid at the feeding device returns to the evaporation and concentration device 1 along the sixth pipe 60, and so on.
