Sulfitation intensity on-line automatic detection apparatus

Abstract

The invention relates to an online automatic detector of sulfur fumigating strength, which comprises a vacuum pump, a neutral water metering cup, a cane juice cup, a mixing cup, a vacuum bottle, an iodine solution metering wiggling pump, a step counting motor, relative pipelines, a control switch, etc. The detection has the following steps: step 1, the vacuum pump is started to evacuate the air in the cane juice cup, the cane juice is sucked into the cup, and a certain volume of neutral water is taken in the neutral water; step 2, the two liquids are placed into the mixing cup, the iodine solution simultaneously enters the mixing cup by the iodine solution metering wiggling pump, and after the three liquids are evenly stirred in the mixing cup and chemically reacted, the relative sulfur fumigating strength and parameters can be obtained after transmitting displayed relative data into a computer and processing the relative data. The computer is used for control, and thus, the sulfur fumigating strength of the cane juice in the production process can be detected on line at any time. The invention has the advantages of simple structure, safe and reliable use and convenient repair and maintenance, provides reliable technical guaranty for the automatic control of enterprise production, and increases the product quality and the economic benefits of the enterprise.

Description

Technical field [0001] The invention relates to an on-line automatic detection device for sulfur fumigation intensity, which is mainly used for on-line automatic detection of sulfur fumigation intensity in the sulfite sugar production process used in sugar factories. Background technique [0002] At present, domestic sugarcane sugar factories generally use sulfur dioxide gas to fumigate sugarcane juice in order to make the white sugar pure and white, and improve the color and grade of the sugarcane juice in the sulfite sugar production process, so that the cloudy pre-ash sugarcane The sugarcane juice is neutralized by sulfur fumigation and heated to form large-grained precipitates. These precipitates can remove most of the colloidal suspended matter and pigment impurities in the sugarcane juice, so that the next process can be successfully separated into clear and transparent sugarcane juice. The light-colored clear juice makes the quality of sugar better and the economic be...

Problems solved by technology

However, sulfur fumigation also has a bad side, that is, if the concentration of sulfur dioxide added is large or too high, the sulfur content in sugar will exceed the standard. For the food industry, the national standard for sulfur residues in food It is very strict. If the product is checked and found to exceed the standard, it cannot leave the factory. Therefore, all enterprises attach great importance to the key technical issue of the sulfur fumigation process.

However, due to the low degree of automation in domestic sugar factories, there are few technologies in this area, and there are no patent documents. The determination of sulfur fumigation intensity in various sugar factories still adopts the traditional manual detection method.

The disadvantages of manual detection are that it is greatly affected by human factors, the measurement and control cycle is long, the control effect varies from person to person, the error is large, and the labor intensity is high, making it difficult to guarantee the accuracy of measurement data.
