[0020] Combined with Figure 1-2 As shown, the technical scheme is further described, a glucose continuous production device includes a reaction tank 1, a storage tank 2 arranged on the reaction tank 1, an acid liquid tank 3 arranged on the reaction tank 1, and a pH adjustment component 4 arranged between the reaction tank 1, the storage tank 2 and the acid liquid tank 3, the pH adjustment component 4 includes a first metering pump 40 arranged between the reaction tank 1 and the storage tank 2, a second metering pump 41 arranged between the reaction tank 1 and the acid liquid tank 3, and a pH tester 42 arranged on the reaction tank 1 for testing the pH value of the liquid in the reaction tank 1.

[0021] The present application provides a glucose continuous production device, comprising a reaction tank, a material storage tank arranged on the reaction tank, an acid liquid tank arranged on the reaction tank, and a pH adjustment component arranged among the reaction tank, the material storage tank and the acid liquid tank, wherein the pH adjustment component comprises a first metering pump located between the reaction tank and the material storage tank, a second metering pump located between the reaction tank and the acid liquid tank, and a pH tester located on the reaction tank, the pH tester is used to reflect the reaction degree in the reaction tank in real time, and the flow rates of the material liquid and the acid liquid transported into the reaction tank are adjusted by the first metering pump and the second metering pump respectively, without the need for manual control by an operator, and without the need for the operator to visually judge the reaction end point in the reaction tank through iodine test paper, thereby reducing human errors, reducing the purity fluctuation of the finished product, and improving product quality, and having the advantages of high degree of automation, efficient and simple operation, low implementation cost, and easy promotion and implementation.

[0022] During the implementation of this embodiment, the material storage tank 2 is provided with a first weight sensor for measuring the weight of the material liquid therein, and the acid liquid tank 3 is provided with a second weight sensor for measuring the weight of the acid liquid therein.

[0023] During the actual implementation process, the pH tester, the first metering pump and the second metering pump are proportionally controlled by PLC. When the pH value measured by the pH tester is higher than its preset value, the second metering pump starts and adds acid to the reaction tank, so that the pH value in the reaction tank is reduced to the preset value of the pH tester; when the pH value measured by the pH tester is lower than its preset value, the first metering pump starts and adds feed liquid to the reaction tank, so that the pH value in the reaction tank rises to the preset value of the pH tester; the first metering pump and the second metering pump can record the flow rate of feed liquid or acid liquid input into the reaction tank and the start and shutdown time, and then measure the replenishment amount of feed liquid and acid liquid, and then calibrate with the weight sensed by the first weight sensor and the second sensor, without the need for manual control by the operator, and without the need for the operator to judge the reaction end point in the reaction tank by naked eyes through iodine test paper, thereby reducing human errors, reducing the purity fluctuation of the finished product, and improving product quality. It has the advantages of high degree of automation, efficient and simple operation, low implementation cost, and easy promotion and implementation.

[0024] During the actual implementation process, the pH tester is also equipped with a buzzer. When the pH tester detects that the pH value is 10% higher than the preset value, the buzzer starts to ensure the reaction pH value of the reaction tank during the actual reaction process. There is no need for manual control by the operator, and there is no need for the operator to use iodine test paper to visually judge the reaction end point in the reaction tank. This reduces human errors, reduces fluctuations in the purity of finished products, and improves product quality. It has the advantages of high degree of automation, efficient and simple operation, low implementation cost, and is easy to promote and implement.

When the feed liquid in the storage tank 2 and the acid liquid in the acid liquid tank 3 are transported to the reaction tank 1, the ejector 6 is used to eject high-temperature steam to the acid liquid and the feed liquid.

[0028] In the actual implementation process, high-temperature steam is sprayed into the feed liquid and acid liquid through an ejector, which can instantly raise the temperature of both to the reaction temperature without the need for continuous heating, thereby improving heating efficiency and speeding up the production process. It has the advantages of easy operation and continuous production.

[0029] During the implementation of this embodiment, a plurality of temperature sensors are arranged at intervals on the inner wall of the reaction tank 1 along its height direction.

The finished liquid in the pressure tank 50 can be transported to the flash tank 7 after passing through the heat exchange tower 51. The flash tank 7 is used to concentrate the finished liquid.

[0032] In the actual implementation process, while the heat exchange tower is keeping the finished liquid in the pressure tank warm, the excess heat can be used in the flash tank to concentrate the finished liquid. By recovering heat energy and cooling the flash tank, continuous production can be achieved.

[0033] During the implementation of this embodiment, an elution tower 8 is provided on the flash tank 7, and an elution component 9 is provided inside the elution tower 8 along its height direction.
