Embodiment 1

[0028] Such as figure 1 Among them, a concentration system used in the isoleucine extraction process, the liquid outlet of the desorption liquid storage tank 1 is connected to the tube side of the heat exchanger 3 through a pipeline, and the tube side of the heat exchanger 3 is connected to the tube side of the concentrator 4 The liquid inlet is connected, and the shell side of the heat exchanger 3 is connected with the steam tail gas pipeline. With this structure, the isoleucine desorption solution is heated and then enters the concentrator 4 for concentration, which improves the concentration efficiency.

[0029] preferred as figure 1 Among them, the shell side of the heat exchanger 3 is connected with the steam tail gas pipeline of the sterilization device 2 .

[0030] Preferably, the heat exchanger 3 is a shell and tube heat exchanger. The shell and tube heat exchanger used in this example has a heat exchange area of ​​18 cubic meters.

[0031] preferred as figure 1 A...

Embodiment 2

[0038] On the basis of Example 1, a method for concentrating using the above-mentioned concentrating system used in the isoleucine extraction process, the temperature of the inlet material of the heat exchanger 3 tube side, that is, the temperature of the desorption liquid is lower than the temperature of the outlet material by 8- 12°C. Preferably, the temperature of the inlet material in the tube side of the heat exchanger 3 is lower than the temperature of the outlet material by 10°C.

[0039] Preferably, the temperature of the material at the outlet of the tube side of the heat exchanger 3 is less than 37°C.

[0040] Specifically, the desorption liquid from the desorption liquid storage tank 1 enters the tube side of the heat exchanger 3, is heated by the remaining steam from the sterilization device 2 for fermentation and sterilization at 10±10°C, and enters the scraper in the concentrator 4 through the pipeline Film formation, hot air enters from the bottom of the tower ...

Abstract

The invention discloses a concentration system applied to an extraction process of isoleucine. A solution discharging hole of a desorption solution storage tank is connected with a pipe side of a heat exchanger by virtue of a pipeline, wherein the pipe side of the heat exchanger is connected with a solution charging hole of a concentrator; a shell side of the heat exchanger is connected with a steam tail gas pipeline. The invention also discloses a method for concentrating by using the concentration system applied to the extraction process of isoleucine. The temperature of the inlet material of the pipe side of the heat exchanger is lower than the outlet material by 8-12 DEG C. According to the concentration system and the concentration method applied to the extraction process of isoleucine, the concentration system is integrally improved; the concentration efficiency is effectively improved; the crystallization phenomenon caused by heating of the heat exchanger can be avoided; the blockage of a pipe array of a heater is avoided; the heat exchanger is stable in heat exchange effect and relatively convenient to maintain.

Description

technical field [0001] The invention relates to the field of isoleucine extraction technology, in particular to a concentration system and method used in the isoleucine extraction technology. Background technique [0002] In the isoleucine extraction process, the primary concentration post needs to concentrate the desorption liquid produced by the separation post, and then the concentrated material is centrifuged to obtain a crude product, which is used in the subsequent production process. The production of a concentration post has a great impact on the entire workshop. Due to the limited concentration production capacity of the concentrator, or when the production task increases, the output of the fermentation tank will increase significantly, the production batch will increase, and the volume of the desorption liquid will increase. The concentration post brought a lot of pressure; coupled with the influence of external factors such as water and steam stoppages, as well as...
