Multi-sensor online liquor picking system with liquid level control function

Abstract

The invention relates to a multi-sensor online liquor picking system with a liquid level control function. The multi-sensor online liquor picking system comprises a liquor collector, a raw liquor lifting and conveying pump, a refractometer, a liquor quality information collector, a No.1 temperature sensor, a tuning fork density sensor, a flow sensor, a power motor, a liquid level sensor and a No.2 temperature sensor. Raw wine is introduced into an inlet in the upper part of the wine collector, an outlet in the lower part of the wine collector is connected with the pumping-in end of the raw wine lifting and conveying pump, and the pumping-out end of the raw wine lifting and conveying pump is connected with the wine quality information collector. The output end of the power motor is connected with the power input end of the raw wine lifting and conveying pump. The tuning fork density sensor, the No.1 temperature sensor and the flow sensor are mounted at the upper part of the wine quality information collector, and the refractometer and the No.2 temperature sensor are mounted at the lower part of the wine quality information collector. The liquid level sensor is positioned on the wine collector. According to the system, information collected by multiple sensors is fused, the alcoholic strength is detected, errors caused by human and environmental factors are effectively reduced, and the wine picking accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of liquor brewing, in particular to a multi-sensor online wine picking system with liquid level control. Background technique [0002] At present, the traditional liquor brewing industry mainly uses manual viewing of flowers for wine picking, that is, workers observe the shape, quantity and shape retention time of the hops of the distilled original wine through their eyes, estimate the alcohol content range, and then roughly estimate the current original wine through the skin temperature of the original wine. Alcohol content, this method is greatly affected by individual subjective factors. Different wine picking workers have inconsistent judgment methods and boundary conditions for hops, resulting in different wine picking standards in the process of mass production, reducing the rate of high-quality wine.

[0004] The document with the application number 202020696851.5 discloses a liquor picking system. The system uses a high-resolution camera to collect the hops produced after liquor distillation, identifies the hops, and picks the wine based on the hops. The system still uses the hops to carry out graded wine picking. , although a high-resolution camera is used to collect images of hops, but the hops themselves are greatly affected by environmental factors, so the reliability is poor

[0005] The document with the application number 202110148060.8 discloses an online alcohol detection method and system for segmental picking of wine. The system uses a differential pressure density sensor and a temperature sensor to detect the density and temperature of the flowing wine, and then uses the density value and The temperature value is combined with the calculation of the alcohol content. The system structure and method are relatively simple. Although it can detect the alcohol content online, other influencing factors are not considered, and the detection accuracy is low.
