Color-sensor-based device for detecting intensity of stoving

Abstract

The invention discloses a color-sensor-based automatic-titration device for detecting the intensity of stoving. The device comprises a precision sampling device, a cleaning device, a precision titration device, a color sensor, an embedded processor and output equipment. During detection, each of two liquid taking devices takes a quantitative sugarcane juice liquid and a quantitative starch liquid through measuring, the sugarcane juice liquid and the starch liquid are conveyed to a titration bottle through a peristaltic pump, an iodine solution is slowly titrated into the titration bottle through a measuring injection pump, and quick stirring is carried out for reaction; the embedded processor is used for turning off a titration injection pump according to color change signals of the liquid reactants at titration end points, which are transmitted by the color sensor in real time, so as to obtain the accurate intensity of stoving, and powerful technical supports and guarantees are provided for the production of sugar enterprises.

Description

technical field [0001] The invention relates to an on-line detection device for sulfur fumigation intensity in a sugar making process. In particular, it is a device for detecting the end point of automatic titration based on color sensors for the detection of sulfur fumigation in the sugar making process. Background technique [0002] The sugar cane sugar production process is mainly divided into several processes: juice extraction, cleaning, evaporation, boiling sugar crystallization and honey separation. In the cane juice cleaning process, most sugar factories in my country use the sulfite method. Sulfurous acid method refers to the introduction of sulfur dioxide gas in the clarification process section, a part of the sulfur dioxide reacts with the lime added earlier at high temperature to form calcium sulfite flocs, so that the colloidal substances in the sugarcane juice settle to achieve the purpose of clarification, and the other part of the sulfur dioxide is mixed wit...

Problems solved by technology

[0003] In order to overcome the high labor intensity, low operating efficiency, relatively low measurement accuracy and reproducibility of manual detection, it is greatly affected by the external environment such as human operation level and the detection cannot provide real-time adjustment for the sulfur fumigation device. The shortcoming of information, the present invention provides a kind of device of real-time on-line detection sulfur fumigation intensity, this device can detect the sulfur fumigation intensity value in the sulfur fumigation process section of sugar factory on-line accurately in real time, provides real-time and accurate information for the throughput of sulfur dioxide. in accordance with
