Description

Real-Time Spectroscopy and Spectroscopy Method {APPARATUS AND METHOD FOR SPETROSCOPIC ANALYSIS IN-SITE}

The present invention relates to a spectroscopic analysis device, and more particularly, to a real-time spectroscopic analysis device and a spectroscopic analysis method that can shorten the measurement time and improve the accuracy of the measurement.

Starch sugar is a carbohydrate obtained by hydrolyzing starch with sugar-containing starch. The starch sugar may be generically defined from starch syrup to glucose. Hydrolysis of starch with acids or enzymes leads to progressively smaller molecules and finally to glucose, the monosaccharide.

Main raw materials of starch sugar include corn, tapioca, potato, sweet potato, etc., and the produced starch sugar can be decomposed into syrup, mortgage, fructose, glucose, oligosaccharide, etc. through the process of liquefaction, saccharification, decolorization and concentration. The starch sugar or its degradation products thus obtained are used in most food products such as ice cream, confectionery, bakery, chocolate, and beverages.

In particular, various kinds of sugars can be produced depending on the degree of decomposition, for example, glucose equivalent (dextrose equivalent, DE) in the manufacturing process of starch sugar, and the physicochemical properties of these decomposition products, such as sweetness, hygroscopicity, viscosity, etc. This can vary.

When producing starch sugar, mortgage, fructose, glucose, etc. during starch sugar production process, it is required to satisfy the appropriate ingredient standard.As a measure of the current ingredient standard, an operator collects a certain amount of sample from the object and uses HPLC (high performance liquid chromatography). Or by spectroscopic analysis. After measuring the specific parameters from the sample with the sample collected specifically, the component standard is measured through the complicated process of generating the analysis model and verifying the analysis model again. Among them, offline measurement technology using HPLC is the mainstream.

This measuring method is a manual control method by an operator or a manager, which takes a long time (ex. About 2 hours), and collects only about once every 2 hours, which lowers the reliability of the representativeness of the sample. Failure to meet the quality standards can result in excessive losses because a large amount of starch sugar or degradation products must be disposed of or disposed of for other purposes.

In addition, in fact, the variety of starch sugar is difficult to control the production process, the conventional method, which takes about two hours for one time inspection to comply with the quality or ingredient standards in the production process has a lot of problems. As well as manpower required for sample measurement, contamination of the entire sample may occur during the sample collection process itself, and there is a problem that unnecessary energy is consumed because the overall production efficiency and yield are reduced.

Recently, a method of measuring a starch sugar component reference by introducing a spectrometer has been introduced, but the above-described problems remain in that there are still many deficiencies in connectivity such as process control.

The present invention provides a spectroscopic analysis device and a spectroscopic analysis method which can control the production process collectively and can quickly complete the component analysis of starch sugar.

The present invention provides a spectroscopic analysis device and a spectroscopic analysis method capable of simultaneously measuring a plurality of components contained in a sample by one measurement.

The present invention provides a spectroscopic analysis device and a spectroscopic analysis method that can efficiently arrange the production time and manpower, improve the efficiency and yield of the production process, and consequently also expect energy saving effects.

In addition to improving the quality of starch sugar, it provides an excellent database of related data and provides an easy-to-maintain and easy-to-maintain spectroscopic analyzer and spectroscopic method.

In addition, each spectroscopic module can be used complementarily to facilitate the maintenance, maintenance and management of the equipment.

In general, photodetectors using CCDs, InGaAs, and PbS have different elements, and therefore, a difference in sensitivity to the same amount of light is inevitable. However, by using a plurality of spectroscopic analysis modules having different characteristics, and by adjusting the appropriate amount of light according to the spectroscopic sensors used in each spectroscopic analysis module to overcome the problems caused by the above differences, while the upper and lower regions Complementary spectral analysis results can easily detect lens defects and foreign material adhesion.

In the present specification, the optical fiber path means an optical path delivered to each spectroscopic module, and such an optical path may be provided using one or two or more optical fibers. For example, spectrometers can use monochromators to increase the accuracy of analyses; spectroscopic modules for the 300-1100 nm wavelength band, spectroscopic modules for the 900-1700 nm wavelength band and spectroscopic analysis for the 900-2100 nm wavelength band.

1 is a view for explaining a spectroscopic analysis device according to an embodiment of the present invention.

Referring to FIG. 1, the spectroscopic analyzer 100 according to the present exemplary embodiment includes a light source 110, a collimating member 120, a light collecting unit 130, a light transmitting unit 170, and three spectroscopic analysis modules 140. , 150, 160). When light is generated from the light source 110, the light is converted into parallel light while passing through the collimating member 120. After the parallel light passes through the sample 10, the light is directed toward the light collecting unit 130, and the focus of the light in the light collecting unit 130 may be adjusted to be positioned at the end of the light transmitting unit 170.

Ends of the bundles of optical fibers may be provided to be located at a focal point collected by the condenser 130, and at the focal point, the light transmitting unit 170 may receive light and transmit light to each optical fiber path. In general, a plurality of bundles of optical fibers may be provided, and may be provided in various combinations, such as three or six, and the optical fibers may also be provided with the same material or different materials.

The configuration of the lens constituting the collimating member 120 or the light collecting unit 130 may refer to the lens configuration of the existing optical device or another lens configuration capable of implementing the same function, and the specific structure thereof is related to the related art. Can be referenced.

Each of the optical fiber paths constituting the light transmitting unit 170 is provided with spectroscopic analysis modules 140, 150, and 160, and each of the spectroscopic analysis modules 140, 150, and 160 is provided with light intensity controllers 142, 152, and 162. Sensor units 144, 154, and 164 may be provided. Each optical sensor unit 144, 154, or 164 may use a photodetector using CCD, InGaAs, and PbS, and in some cases, a lens, mirror, semi-mirror structure, etc., in addition to a filter for passing only a specific wavelength of light. It may further include.

Due to the limitation of the grating technology, it is not possible to ensure that the spectroscopic analysis modules 140, 150, and 160 match the correct wavelength bands. However, in the process of generating and verifying the analytical model, for example, as shown in FIG. Spectroscopic analysis module 140 for the 1100nm wavelength band, spectroscopic analysis module 150 for the 900 ~ 1700nm wavelength band and spectroscopic analysis module 160 for the 900 ~ 2100nm wavelength band can be used.

For reference, the spectroscopic analysis module 140 for the 300 to 1100nm wavelength band uses a photodetector using a CCD device, and the spectroscopic analysis module 150 for the 900 to 1700nm wavelength band may use a photodetector using an InGaAs device. In addition, the spectroscopic analysis module 160 for the wavelength range of about 900 to 2100 nm may use a photodetector using a PbS device.

The sample 10 is continuously measured while passing between the collimating member 120 and the light collecting part 130, and the spectroscopic analyzer 100 can shorten the measurement time significantly, thereby allowing precise control.

The light amount controllers 142, 152, and 162 may independently control the amount of light flowing into each of the optical sensor units 144, 154, and 164, and as described above, the basic physical sensitivity depends on the CCD, InGaAs, and PbS photodetectors. You can also correct the difference. For reference, conventionally, the optical attenuator was applied in a batch to distinguish the difference according to each sensor, and a method of adjusting an operation time or an integration time was used, but this also caused an error as a software control. There is a problem.

In addition, defects of the collimating lens or foreign matter adhesion of the lens can be detected in the spectral analysis module of the lower region. In this embodiment, the detection can be compensated for in the spectral analysis module 140 of the lower region. Depending on the wavelength band, the spectroscopic analysis modules 150 and 160 may complement each other through other additional functions.

Of course, it is possible to change the measurement for each wavelength band in the monochromatometer method, but for this purpose, the measurement time is long because the motor has to rotate for filtering, and there is a limit in shortening the measurement time. However, the spectroscopic analysis apparatus 100 according to the present embodiment uses an independent spectroscopic analysis module for each wavelength band, and can independently control the amount of light according to each optical sensor and spectroscopic analysis method, and complement the results of each module. This makes it easier to recognize more accurate measurement values and device defects.
