Our company and Wang Zhaoguo Jet Liquefaction Technology Group applied Yudian AI-808A2XL2L2S4 automatic intelligent control [low pressure steam (≥0.30Mpa) continuous liquefied pneumatic injector] in the design of special equipment for starch sugar. The ejector is the key equipment to complete the instant starch gelatinization and liquefaction. Whether it can accurately execute the process parameters has a great influence on the entire production process.
On the basis of digesting and absorbing foreign advanced technology, the company has developed a fully automatic AI intelligent control continuous liquefaction ejector combined with the actual situation in China. The equipment has reached the domestic leading level after production practice and has been widely used in the starch industry.
Take Yudian AI-808 display control instrument as an example:
Provided with manual auto-tuning mode. The method is to set the given value first and then adjust it manually. After the manual adjustment system is basically stable, then start auto-tuning in manual state, so that the output of the injector will be limited to the current manual value + 10% and -10 % Range, thus avoiding the phenomenon that the continuous liquefaction injector does not allow the valve to change significantly. After the continuous liquefied ejector oscillates for 2 to 3 times, the internal microprocessor of the instrument will oscillate according to the position control, analyze its period, amplitude and wave pattern to automatically calculate M5, P, T and other control parameters and then complete the setting. The rapid response of the continuous liquefaction injector enables manual self-tuning to obtain more accurate self-tuning results. Summary The above functions are selected:
Xiamen Yudian AI-808A2XL2L2S4 enhanced artificial intelligence regulator constitutes an independent control system. It automatically adjusts the steam flow to control the temperature after spraying, so that the starch milk and steam are mixed more uniformly, and the spray temperature is kept constant. Computer centralized control is adopted.

Step 1: Set the given value Step 2: Press the manual / automatic switch A / M key to switch to manual Step 3: First adjust the valve in manual mode, wait for the manual adjustment to be basically stable, and then start the manual mode Set, press the A / M key for 2 seconds, the word "At" appears, at this time the output value of the instrument is limited to the range of the current manual value ± 10%, instead of the range defined by OPL and OPH, thus avoiding the production site from allowing large valves The phenomenon of amplitude change. After 2 to 3 oscillations, the display stops flashing "At". At this time, the self-tuning parameters M5, P, t automatically calculate the control parameters.
In addition, when the controlled physical quantity reacts quickly, manual auto-tuning can obtain more accurate auto-tuning effect.
The entire auto-tuning process takes 5 minutes, and then the steam flow is automatically adjusted to control the temperature after the ejector, so that the spray temperature is kept constant, the starch milk and steam are mixed more uniformly, the liquefaction is complete, and the starch conversion rate and total dry matter yield are increased and decreased. Cost, save energy and increase efficiency.
AIFCS host computer software displays the process flow chart. The liquefied pneumatic injector has an operating platform that can be set to a given value, which can be manually / automatically switched. When in manual state, a manual output value can be set to change the position of the valve. 12 parameters are displayed simultaneously Data, curve and deviation alarms, real-time reminders appear at any time to achieve long-distance monitoring, communication distance up to 1200 meters.
Starch continuous liquefaction pneumatic injector is the key equipment for enzymatic starch liquefaction. Widely used in monosodium glutamate, alcohol, beer, citric acid, glucose, maltose, maltodextrin and other industries to liquefy starch, the device is small in size, high efficiency, low energy consumption. Using double enzyme method to make sugar, the liquefaction is uniform, the saccharification DE value is high, the filtration speed of the sugar liquid is fast, and the color is light. The ejector is suitable for medium and high temperature enzyme preparations. It is also suitable for the direct process of different raw materials such as sweet potato, corn and rice. The ejector has been used in more than 100 monosodium glutamate factories and starch sugar factories across the country. Models are: SLJ? 9â…¡ type: processing starch milk 4 ~ 6M 3 / hour; SLJ? 1 type: processing starch milk 8 ~ 30M 3 / hour. It can also be equipped with auxiliary equipment for industrial production, which is a promising research and production equipment that is expected to achieve greater economic benefits.
