Problems solved by technology

At present, the measurement of sugar liquid brix, purity and the purity of its finished products is still in the manual detection method, and there is no rapid measurement or online measurement equipment. The manual measurement process is: the inspector returns to the laboratory after taking samples from each testing point , the high-concentration sugar solution and sugar products are first weighed with a balance of a certain weight of sugar solution or sugar products and corresponding weight of distilled water as required, and the ratio or multiple of sugar water is calculated, and then the sugar water is mixed and stirred evenly to form a low-concentration sugar solution. Measuring cylinder or other containers, measure the hammer and temperature with a glass vibrometer or refractometer, then take a small amount of low-concentration sugar solution, measure the optical rotation with a polarimeter, and finally calculate the hammer and purity of the original sugar solution by manual calculation. Then record the measured value and hand it over to the relevant operator
The entire operation process is very time-consuming and cumbersome, and does not have much guiding effect on the real-time production process

Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention will be further described:

[0030] figure 1 As shown, it is a schematic diagram of the control structure of the present invention. The automatic measuring device for the brix and purity of the sugar liquid of the present invention is mainly composed of a PLC 1, a touch screen 2, a sample dilution device 3 and a detector 4 comprising a brix detector and an optical rotation detector. , PLC1 is electrically connected with the touch screen 2, the sample dilution device 3 and the detector 4 through relevant connection lines. The operator sends instructions to PLC1 through the touch screen 2, and PLC1 can automatically control the operation of the sample dilution device 3 and the detector 4, and receive the detection data information fed back by the sample dilution device 3, Brix and purity detector 4, and process the data , and display the processing or calculation results on the touch screen 2 .

Abstract

The invention provides an automatic measurement device and method for brix and purity of sugar liquor. The measurement device comprises a touch screen, a programmable logic controller (PLC), a sample dilution device and a detection device, wherein the sample dilution device and the detection device are controlled by the PLC, detected data are transmitted to the PLC to perform processing, and final results are displayed on the touch screen. The measurement method comprises the steps of program composition, sugar liquor dilution, measurement of the brix and the temperature of the diluted sugar liquor, measurement of specific rotation of the diluted sugar liquor and the like. By means of the automatic measurement device and method for the brix and the purity of sugar liquor, the brix and the purity of the sugar liquor can be quickly detected, operators can know about situations of indicators including the brix and the purity of the sugar liquor quickly, accurately and comprehensively to adjust corresponding operation timely, and accordingly, quality of the sugar liquor is improved. Besides, the PLC is used in the measurement device, so that automatic detection is achieved. Therefore, compared with the traditional manual detection method, detection time is greatly shortened, and working efficiency and measurement accuracy are improved.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for industrial production, in particular to an automatic measuring device and a measuring method for the brix and purity of sugar liquid in the sugar industry. Background technique [0002] In the sugar industry production, the measurement of the brix and purity of the sugar liquid is not only the inspection of the results of each process in the sugar production process, but also the main basis for controlling the production operation. Among them, the brix represents the concentration of sugar in the sugar liquid, and the purity represents the sucrose content in the sugar liquid; the brix and purity of the sugar liquid and the purity measurement of its finished products have very important significance in the sugar industry. At present, the measurement of the brix, purity and the purity of its finished products is still in the manual detection method, and there is no rapid measurement o...
