[0030] In order to better understand the technical solutions provided by the embodiments of the present specification, the technical solutions of the embodiments of the present specification will be described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present specification and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present specification, and are not limitations of the technical solutions of the present specification. In the case of no conflict, the technical features in the embodiments of the present specification and the embodiments can be combined with each other.

Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the element defined by the statement "including a" does not exclude the presence of another identical element in the process, method, article or equipment including the element. The term "more than two" includes two or more than two.
[0032] The present application provides a processing assembly 100 for microbial protein. It can be understood that fermentation liquid will be produced in the process of industrial fermentation, and the protein in the fermentation liquid is microbial protein.
[0033] Referring to Figure 1 , the processing assembly 100 for bacterial protein includes a first liquid storage tank 1, a steam ejector 2, a second liquid storage tank 3, and a filtering device (not shown in the figure).
[0034] The first liquid storage tank 1 is used to store a bacterial stock solution 12, which is a fermentation liquid of a fermentation process. The steam ejector 2 has a mixing space formed therein, which is provided with a liquid inlet 21, a steam inlet 22, and a steam outlet 23. The liquid inlet 21 is used to communicate with the first liquid storage tank 1. The steam inlet 22 is used to be communicable with steam 25 in an on-off manner. The steam outlet 23 is used to communicate with the second liquid storage tank 3. The filtering device communicates with the second liquid storage tank 3.
[0035] In this way, the bacterial stock solution 12 can enter the mixing space of the steam ejector 2 from the first liquid storage tank 1 through the liquid inlet 21. The steam 25 can enter the mixing space of the steam ejector 2 from the steam inlet 22. At this time, the steam 25 will contact the bacterial stock solution 12 to heat the bacterial stock solution 12. Since the temperature of the steam 25 is high, the steam 25 can instantaneously heat the bacterial stock solution 12, that is, the denaturation of the bacterial protein is realized, and high-temperature sterilization is also realized, thereby ensuring the product quality. At the same time, the heating efficiency is high, and the shortcoming of deepening the color of the bacterial protein product caused by long-time heating can be avoided. In addition, after the bacterial protein is denatured by heat, the separation performance of the bacterial protein is improved.
[0036] Then, the sterilized bacterial stock solution 12 forms a sterilized liquid 31, which enters the filtering device. The filtering device can filter the bacterial protein of the sterilized liquid 31 to realize the separation of the bacterial protein.
[0037] According to the processing assembly 100 for bacterial protein provided in the embodiments of the present application, the bacterial stock solution 12 can be mixed with the steam 25 in the mixing space, so as to instantaneously heat the bacterial stock solution 12 by using the steam 25, that is, the denaturation of the bacterial protein is realized, and the product quality is ensured, and the shortcoming of deepening the color of the bacterial protein product caused by long-time heating is avoided. In addition, after the bacterial protein is denatured by heat, the separation performance of the bacterial protein is improved. The filtering device can filter the heated bacterial protein to realize the separation.
[0038] In some embodiments, as shown in Figure 1 , the filtering device includes a vacuum drum filter device 5, which communicates with the second liquid storage tank 3.
[0039] It can be understood that the vacuum drum filter 5 is a kind of continuous filter, and the filtration is driven by negative pressure, so that the sterilized liquid 31 after heating can be filtered by the vacuum drum filter 5 to form the concentrated bacterial liquid 51, so as to improve the concentration of the bacterial protein. For example, the concentration of the bacterial stock solution 128g-10g / L can be increased to 12g-15g / L after being filtered by the vacuum drum filter.
[0040] In some embodiments, as shown in Figure 1 The filtration device further comprises a plate-and-frame filter press 6, which is in communication with the outlet of the vacuum drum filter 5.
[0041] Therefore, the concentrated bacterial liquid 51 filtered by the vacuum drum filter 5 can be filtered again by the plate-and-frame filter press 6 to form the wet bacterial protein 61.
[0042] It should be noted that the process of plate-and-frame filter press generally requires the addition of flocculants to increase the concentration of the material, but the addition of flocculants is not suitable for products with high quality requirements. Since the vacuum drum filter 5 and the plate-and-frame filter press 6 are provided in the present application, the sterilized liquid 31 can be filtered twice, so that the flocculants do not need to be added in the process of plate-and-frame filter press. The vacuum drum filter 5 as a pretreatment process of the plate-and-frame filter press 6 plays a role in pre-concentration of the material, solves the problem of low feed concentration, and improves the production efficiency.
[0043] In some embodiments, the bacterial protein processing assembly further comprises a recovery device in communication with the vacuum drum filter 5 and / or the plate-and-frame filter press 6.
[0044] Therefore, the liquid after filtering the bacterial protein can be recovered by the recovery device. For example, the recovery device comprises a clear liquid tank 73 and a clear liquid lifting pump 74, as shown in Figure 1 The vacuum filtered clear liquid 71 filtered by the vacuum drum filter 5 can enter the clear liquid tank 73, and the plate-and-frame filtered clear liquid 72 filtered by the plate-and-frame filter press 6 can also enter the clear liquid tank 73, so as to recover the liquid after filtering the bacterial protein, and then the clear liquid lifting pump 74 can pump the liquid in the clear liquid tank 73 to a sewage treatment process.
[0045] In some embodiments, as shown in Figure 1 The bacterial protein processing assembly further comprises a first heat exchanger 8, which is provided with a first heat exchange pipeline and a second heat exchange pipeline. The first heat exchange pipeline is in communication between the second liquid tank 3 and the vacuum drum filter 5, and the second heat exchange pipeline is provided with a heat exchange gas and is used for heat exchange with the first heat exchange pipeline.
[0046] Thus, the heat exchange gas in the second heat exchange pipeline can exchange heat with the sterilization liquid 31 flowing to the vacuum drum filter device 5 through the first heat exchange pipeline, so as to reduce the temperature of the sterilization liquid 31, thereby avoiding the shortcoming that the product color is deepened due to long-time heating.
[0047] In some embodiments, as shown in Figure 1 The bacterial protein processing assembly further comprises a second heat exchanger 9, the second heat exchanger 9 is provided with a third heat exchange pipeline and a fourth heat exchange pipeline, the third heat exchange pipeline is communicated with the second heat exchange pipeline, and the fourth heat exchange pipeline is communicated with the third heat exchange pipeline and used for heat exchange.
[0048] Thus, the third heat exchange pipeline and the second heat exchange pipeline are communicated, so that the heat exchange gas in the second heat exchange pipeline can flow to the third heat exchange pipeline, and then can exchange heat with the heat exchange gas in the third heat exchange pipeline through the cooling liquid in the fourth heat exchange pipeline, so as to reduce the temperature of the heat exchange gas in the second heat exchange pipeline, thereby continuously exchanging heat between the heat exchange gas in the second heat exchange pipeline and the sterilization liquid 31 flowing to the vacuum drum filter device 5 through the first heat exchange pipeline, so as to reduce the temperature of the sterilization liquid 31, thereby avoiding the shortcoming that the product color is deepened due to long-time heating.
[0049] In some embodiments, as shown in Figure 1 The bacterial protein processing assembly further comprises a low-temperature drying device 4, the low-temperature drying device 4 is communicated with the downstream of the plate-frame filter press device 6 and between the third heat exchange pipeline and the second heat exchange pipeline.
[0050] Thus, the wet bacterial protein 61 can be dried by the low-temperature drying device 4 to obtain the dry bacterial protein 41, and the low-temperature drying device 4 is communicated between the third heat exchange pipeline and the second heat exchange pipeline, so as to recover the available heat from the heat exchange gas, realize the reuse of waste heat, reduce the energy consumption level, and facilitate the integration of the bacterial protein processing assembly.
[0051] It can be understood that, compared with the spray drying device, the low-temperature drying device 4 saves the electric energy consumption of 180 kWh / t product and saves the steam consumption of about 5 t / t product.
[0052] In some embodiments, as shown in Figure 1 The bacterial protein processing assembly further comprises a cooler 10, the inlet of the cooler 10 is communicated with the outlet of the fourth heat exchange pipeline, and the outlet of the cooler 10 is communicated with the inlet of the fourth heat exchange pipeline.
[0053] Thus, a loop is formed between the fourth heat exchange pipeline and the cooler 10, so as to cool the cooling liquid in the fourth heat exchange pipeline through the cooler 10, thereby continuously cooling the heat exchange gas in the third heat exchange pipeline through the cooling liquid in the fourth heat exchange pipeline. Thus, a loop is formed between the fourth heat exchange pipeline and the cooler 10, so as to cool the cooling liquid in the fourth heat exchange pipeline through the cooler 10, thereby continuously cooling the heat exchange gas in the third heat exchange pipeline through the cooling liquid in the fourth heat exchange pipeline.
[0054] In some embodiments, as shown in Figure 1 An automatic control valve 24 is arranged at the steam inlet 22. In this way, the on-off of the steam 25 can be controlled.
[0055] In some embodiments, as shown in Figure 1 A bacterial liquid lifting pump 11 is arranged between the first liquid tank 1 and the steam ejector 2, so that the bacterial liquid 12 can be pumped into the steam ejector 2 by the bacterial liquid lifting pump 11.
[0056] A specific embodiment of the processing assembly 100 for bacterial protein of the present application will be described below in combination with the accompanying drawings: Figure 1 A specific embodiment of the processing assembly 100 for bacterial protein of the present application will be described below in combination with the accompanying drawings:
[0057] The processing assembly 100 for bacterial protein comprises a first liquid tank 1, a bacterial liquid lifting pump 11, a steam ejector 2, an automatic control valve 24, a second liquid tank 3, a sterilization liquid lifting pump 32, a low-temperature drying device 4, a vacuum drum filter device 5, a concentrated bacterial liquid tank 52, a concentrated bacterial liquid lifting pump 53, a plate-and-frame filter device 6, a vacuum filtration clear liquid 71, a clear liquid lifting pump 7474, a first heat exchanger 8, a circulating fan 82, a second heat exchanger 9, a cooler 10, and a circulating water pump 101.
[0058] The bacterial liquid 12 from the fermentation process is stored in the first liquid tank 1 and is lifted to the steam ejector 2 by the bacterial liquid lifting pump 11. The steam 25 from the utility engineering process enters the steam ejector 2 through the automatic control valve 24. After being ejected by the steam ejector 2, the sterilization liquid 31 is formed and is stored in the sterilization liquid 31 tank. The sterilization liquid 31 is lifted to the vacuum drum filter device 5 by the sterilization liquid lifting pump 32 to form the concentrated bacterial liquid 51, which is stored in the concentrated bacterial liquid 51 tank and is lifted to the plate-and-frame filter device 6 by the concentrated bacterial liquid lifting pump 53 to produce the wet bacterial protein 61. The vacuum filtration clear liquid 71 and the plate-and-frame filtration clear liquid 72 are stored in the clear liquid tank 73, and the external clear liquid 75 is discharged to the sewage treatment process through the clear liquid tank 73.
[0059] The dry hot air 83 enters the low-temperature drying device 4 to remove the water in the bacterial protein with high water content, forming the wet hot air 91. After passing through the second heat exchanger 9, the dry cold air 81 is formed. Under the action of the circulating fan 82, the dry hot air 83 is formed again through the first heat exchanger 8. The qualified dry bacterial protein 41 is produced in the low-temperature drying device 4.
[0060] The circulating water inlet 102 is lifted into the second heat exchanger 9 by the circulating water pump 101, the circulating water return 103 returns to the cooler 10, and the condensed water 104 is discharged from the second heat exchanger 9 and enters the sewage treatment process.
[0061] Therefore, the processing assembly 100 for bacterial protein of the present application at least has the following advantages:
[0062] 1. The steam ejector is arranged to instantaneously heat the bacterial liquid 12, which realizes the denaturation of bacterial protein and ensures the product quality, avoids the shortcoming of deepening the product color caused by long-time heating, and improves the separation performance after the denaturation of bacterial protein.
[0063] 2. The low-temperature drying device 4 is applied to the drying of bacterial protein, and is a drying device with low energy consumption. The available heat is recovered from the high-temperature material in the system, the waste heat is reused, and the energy consumption level is further reduced. At the same time, the circulating air is not discharged, which meets the requirements of environmental protection standards.
[0064] 3. The plate and frame filter press generally needs to add flocculants to improve the material concentration, but flocculants are not suitable for products with high quality requirements. The vacuum drum filter device 5 serves as a pretreatment process of the plate and frame filter press, plays a role in pre-concentration of the material, solves the problem of low feed concentration, and improves the production efficiency.
