The system has the beneficial effects that a heating control system is arranged in the soaking extraction module of the system, and the PID controller is adopted to control the temperature of the extractingsolution in an extraction tank, so that the temperature is accurately controlled; and the evaporation and concentration module adopts a BP neural network to carry out online detection on the concentration of the extracting solution in an evaporator, so that the real-time detection of the detection concentration is achieved.

Description

technical field [0001] The invention relates to the field of plant extraction, in particular to a production process control system for plant extraction. Background technique [0002] Plant extraction is an extraction method that uses plants as raw materials to obtain one or more active ingredients in plants through physical or chemical extraction and separation without changing the structure of the active ingredients. Plants usually contain heat-sensitive substances. At present, the most used extraction process in plant extraction is warm-dipping dynamic extraction. Warm-dipping dynamic extraction keeps the temperature of the extract at a "sub-boiling" state close to the boiling point, and has a high extraction rate. , The advantages of reducing the destruction of active ingredients and the leaching of impurities, but the control accuracy of the extraction temperature is high, and the traditional control method is difficult to meet the temperature precise control requiremen...

Problems solved by technology

Concentration detection is very important in concentration control. Generally, detection is carried out at the later stage of concentration as a discharge standard. Due to the poor internal working conditions of the concentrator and the lack of effective sensor detection methods, it is difficult to accurately determine the concentration
