Portable amylose tester

Abstract

The invention provides a portable amylose tester. The portable amylose tester is packaged with a plastic shell, and comprises an infrared laser light source, an optical fiber probe sampler, a photoelectric detection device, an analog-digital conversion device, a core microcontroller, a key module, a liquid crystal display module and a charging module; wherein the infrared laser light source is used for emitting infrared light which penetrates through a solution to be tested through the optical fiber probe sampler in order to acquire a optical signal transmitted by the solution to be tested; the optical signal is output to the photoelectric detection device to be converted into an electric signal; the electric signal is output to the analog-digital conversion device to be converted into a digital signal which is transmitted to the core microcontroller to calculate the amylose content of the solution to be tested; the acquired data can be exported to an upper computer with an Android mobile phone data line through a USB (Universal Serial Bus) interface in the form of an Excel report; the charging module is charged with a charger and a data line being compatible with most of the Android mobile phones. The portable amylose tester provided by the invention has the advantages of simpleness in structure, easiness in operation, easiness in carrying and high accuracy.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a portable amylose analyzer. Background technique [0002] Amylose is the main nutrient component of corn, wheat, rice, sorghum, potato and other crops. Amylose content has practical significance in evaluating grain quality, agricultural seed selection, breeding, and industrial production, so it is of great significance to develop a rapid detection device for amylose content. [0003] The instruments used to detect amylose in my country's national standards are generally spectrophotometers, which have a low degree of automation and require a degreasing pretreatment step during the detection process, which takes a long time. At present, there are already commercial amylose measuring instruments abroad, such as FLAstar 5000 Analyzer from Foss Company in Sweden and FS-IV chemical automatic analyzer from O-I Company in the United States. However, the above-mentioned instr...

Problems solved by technology

However, the above-mentioned instruments are expensive, bulky, and also require degreasing pretreatment steps, which are not suitable for occasions that require flow monitoring or on-site analysis

The development of amylose measuring instruments in China started relatively late. The DPCZ type amylose measuring instrument based on the colorimetric principle developed by China Agricultural University is cheap and accurate, but it needs to be equipped with a computer as a host computer to control the operation of the instrument. Not only does it increase the cost of the instrument, but the volume is relatively large. In addition, the automatic sampling method using a peristaltic pump is very easy to introduce air bubbles, resulting in inaccurate detection.

[0004] To sum up, the existing amylose content determination device has the problems of complex test device, bulky, expensive, and time-consuming, and is not suitable for the flow monitoring or on-site analysis of the grain quality inspection department.
