Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Figure 1 This is a schematic diagram of the structure of a protein drying system 10 according to an embodiment of the present application, Figure 1The protein drying system 10 includes an air intake unit 100, a heat exchange unit 200, a heating unit 300, a drying unit 400, a dust removal unit 500, an exhaust unit 600 and a deodorization unit 700, wherein the heat exchange unit 200 has a first heat exchange channel and a second heat exchange channel which are isolated from each other and can perform heat exchange, the inlet of the first heat exchange channel is connected to the exhaust port of the air intake unit 100, the outlet of the first heat exchange channel is connected to the air intake of the heating unit 300, the exhaust port of the heating unit 300 is connected to the air intake of the drying unit 400, the exhaust port of the drying unit 400 is connected to the air intake of the dust removal unit 500, the exhaust port of the dust removal unit 500 is connected to the air intake of the exhaust unit 600, the exhaust port of the exhaust unit 600 is connected to the inlet of the second heat exchange channel, and the outlet of the second heat exchange channel is connected to the air intake of the deodorization unit 700.

[0034] Specifically, the air intake unit 100 is used to transport air into the protein drying system 10. Under the action of the air intake unit 100, the air enters from the air intake port of the air intake unit 100, is discharged from the exhaust port of the air intake unit 100, and then enters the first heat exchange channel from the inlet of the first heat exchange channel of the heat exchange unit 200. Subsequently, the air is discharged from the outlet of the first heat exchange channel of the heat exchange unit 200, and enters the heating unit 300 from the air intake port of the heating unit 300. The heating unit 300 is used to inlet the air. The protein mash is heated and the heated air is discharged from the exhaust port of the heating unit 300 and then enters the drying unit 400 from the air inlet of the drying unit 400. The drying unit 400 is used to dry the protein mash to obtain protein powder. The protein mash enters the drying unit 400 from the feed port of the drying unit 400 and the hot air acts on the protein mash to dry the protein mash into protein powder. The hot air is discharged from the exhaust port of the drying unit 400 and the protein powder is discharged from the discharge port of the drying unit 400. The hot air after drying the protein mash in the drying unit 400 contains protein powder. The hot air containing protein powder enters the dust removal unit 500 from the air inlet of the dust removal unit 500 to separate the protein powder in the hot air through the dust removal unit 500. The separated protein powder is discharged from the discharge port of the dust removal unit 500. The hot air after dust removal is discharged from the exhaust port of the dust removal unit 500, and then enters from the air inlet of the exhaust unit 600. The exhaust unit 600 is used to transport the air in the protein drying system 10. Under the action of the exhaust unit 600, the hot air is discharged from the exhaust port of the exhaust unit 600, and then enters the second heat exchange channel of the heat exchange unit 200 from the inlet of the second heat exchange channel, and then the air is discharged from the outlet of the second heat exchange channel of the heat exchange unit 200, and enters the deodorizing unit 700 from the air inlet of the deodorizing unit 700. The deodorizing unit 700 is used to deodorize the hot air. The deodorized air is discharged from the exhaust port of the deodorizing unit 700.

[0035] During the deodorization process of the deodorization unit 700, the hot air needs to be cooled down, and in the process of cooling down the hot air, high energy consumption will be generated. Since the first heat exchange channel and the second heat exchange channel are isolated from each other and can exchange heat, the air in the first heat exchange channel can exchange heat with the hot air in the second heat exchange channel. On the one hand, the air in the first heat exchange channel is preheated by the heat exchange unit 200, thereby reducing the energy consumption of the heating unit 300; on the other hand, the hot air in the second heat exchange channel is cooled down by the heat exchange unit 200, thereby reducing the energy consumption of the deodorization unit 700. In this way, the energy consumption of the protein drying system 10 is reduced as a whole, saving production costs.

[0036] And after calculation, compared with the protein drying system 10 without the heat exchange unit 200, the protein drying system 10 proposed in the embodiment of the present application can, on the one hand, increase the temperature of the air entering the heating unit 300 by more than 30°C through the heat exchange unit 200, so as to reduce the energy consumption of the heating unit 300 by more than 15%; on the other hand, it can reduce the hot air of about 85°C entering the deodorization unit 700 to about 60°C through the heat exchange unit 200, so as to reduce the energy consumption of the deodorization unit 700 by more than 30%, and save water by more than 15%.

[0037] In some embodiments, Figure 1 As shown, the heat exchange unit 200 includes a heat exchanger 210, the shell side of the heat exchanger 210 is a first heat exchange channel, and the tube side of the heat exchanger 210 is a second heat exchange channel, wherein the shell side of the heat exchanger 210 connects the air intake unit 100 and the heating unit 300, and the tube side of the heat exchanger 210 connects the exhaust unit 600 and the deodorization unit 700.

[0038] The shell side and the tube side of the heat exchanger 210 are isolated from each other and can perform heat exchange. Since the hot air will still carry a small amount of dust after dust removal by the dust removal unit 500, the tube side of the heat exchanger 210 is connected between the exhaust unit 600 and the deodorization unit 700 to facilitate cleaning of the dust accumulated in the tube side of the heat exchanger 210.

[0039] In some embodiments, the tube side of the heat exchanger 210 is detachably connected between the exhaust unit 600 and the deodorization unit 700 .

[0040] In order to facilitate the cleaning of dust in the tube of the heat exchanger 210, the tube of the heat exchanger 210 is detachably connected between the exhaust unit 600 and the deodorization unit 700. When the tube of the heat exchanger 210 is blocked, the tube of the heat exchanger 210 can be disassembled for cleaning.

[0041] In some embodiments, Figure 1As shown, the heat exchange unit 200 further includes a first reducer 220 and a second reducer 230 . The first reducer 220 is detachably connected between the pipe side and the exhaust unit 600 , and the second reducer 230 is detachably connected between the pipe side and the deodorization unit 700 .

[0042] Since the shell side of the heat exchanger 210 is connected between the air intake unit 100 and the heating unit 300, the exhaust unit 600, the heat exchanger 210 and the deodorization unit 700 are all fixedly arranged, so that the first reducer 220 is detachably connected between the tube side and the exhaust unit 600, and the second reducer 230 is detachably connected between the tube side and the deodorization unit 700, so that the tube side of the heat exchanger 210 can be cleaned by disassembling the first reducer 220 and the second reducer 230.

[0043] The first reducer 220 and the second reducer 230 can be detachably connected between the pipe side and the exhaust unit 600 and between the pipe side and the deodorization unit 700 by means of threading, clamping, etc., which is not limited in the embodiment of the present application.

[0044] In some embodiments, Figure 1 As shown, the heat exchange unit 200 further includes a heat preservation layer 240 , and the heat preservation layer 240 covers the first reducer 220 and the heat exchanger 210 .

[0045] The first reducer 220 and the heat exchanger 210 are covered with the insulation layer 240 to insulate the hot air entering the heat exchanger 210 from the exhaust unit 600, so as to ensure the preheating effect of the heat exchanger 210 on the air in the shell side. In addition, after the heat exchange, the hot air in the tube side of the heat exchanger 210 no longer needs to be insulated, so the second reducer 230 is not covered.

[0046] In some embodiments, Figure 1 As shown, the protein drying system 10 further includes a first temperature sensor 800 and a second temperature sensor 900. The first temperature sensor 800 is disposed at the inlet of the first heat exchange channel, and the second temperature sensor 900 is disposed at the outlet of the first heat exchange channel.

[0047] The temperature of the air entering the first heat exchange channel of the heat exchange unit 200 is detected by the first temperature sensor 800, and the temperature of the air discharged from the first heat exchange channel of the heat exchange unit 200 is detected by the second temperature sensor 900, so as to determine the preheating effect of the heat exchange unit 200 on the air in the first heat exchange channel.

[0048] In some embodiments, Figure 1As shown, the protein drying system 10 further includes a third temperature sensor 1000 and a fourth temperature sensor 1100. The third temperature sensor 1000 is disposed at the inlet of the second heat exchange channel, and the fourth temperature sensor 1100 is disposed at the outlet of the second heat exchange channel.

[0049] The temperature of the air entering the second heat exchange channel of the heat exchange unit 200 is detected by the third temperature sensor 1000, and the temperature of the air discharged from the second heat exchange channel of the heat exchange unit 200 is detected by the fourth temperature sensor 1100, so as to determine the cooling effect of the heat exchange unit 200 on the hot air in the second heat exchange channel.

[0050] In some embodiments, Figure 1 As shown, the protein drying system 10 further includes a first pressure sensor 1200 and a second pressure sensor 1300 . The first pressure sensor 1200 is disposed at the inlet of the second heat exchange channel, and the second pressure sensor 1300 is disposed at the outlet of the second heat exchange channel.

[0051] The pressure of the air entering the second heat exchange channel of the heat exchange unit 200 is detected by the first pressure sensor 1200, and the pressure of the air discharged from the second heat exchange channel of the heat exchange unit 200 is detected by the second pressure sensor 1300, and by comparing the pressure values ​​detected by the first pressure sensor 1200 and the second pressure sensor 1300, it is determined whether the second heat exchange channel of the heat exchange unit 200 is blocked. In this way, the blockage of the second heat exchange channel of the heat exchange unit 200 can be found in time, and the second heat exchange channel can be cleaned to avoid affecting the operation of the protein drying system 10.

[0052] In some embodiments, Figure 1 As shown, the heating unit 300 includes a steam heater 310 , the outlet of the first heat exchange channel is connected to the air inlet of the steam heater 310 , and the exhaust port of the steam heater 310 is connected to the air inlet of the dust removal unit 500 .

The steam forms condensate after heating the air, and the condensate is discharged from the condensate outlet of the steam heater 310. After the air entering the steam heater 310 is preheated by the heat exchange unit 200, the steam usage of the steam heater 310 is reduced.

[0054] In some embodiments, Figure 1As shown, the heating unit 300 further includes a hot air furnace 320, the exhaust port of the steam heater 310 is connected to the air inlet of the hot air furnace 320, and the exhaust port of the hot air furnace 320 is connected to the air inlet of the dust removal unit 500. After the air entering the steam heater 310 is preheated by the heat exchange unit 200, the gas usage of the hot air furnace 320 is reduced.

[0055] The air heated by the steam heater 310 is further heated by the hot blast furnace 320. The coal gas for combustion enters from the coal gas inlet of the heating furnace, and the coal gas burns in the hot blast furnace 320 to heat the air, and finally the air is heated to about 200°C.
