rice tastometer

1. scope of application

The instrument is mainly used for the analysis of refined rice and brown rice of japonica rice, refined rice and brown rice of indica rice, and four indicators of moisture, protein, amylose and taste value are obtained. The taste value of rice was scored.

The instrument is widely used in rice purchase and reserve links to identify the quality of brown rice. For rice processing plant, rice production line online quality control. Scientific research institutes on rice quality research breeding and other fields.

Principles of 2. Technology

Rice taste meter rice containing hydrogen groups in the near infrared spectral region absorption information to analyze C- H,O-H,N-H and other groups of compounds, related data; using fixed grating spectrometer, COMS linear image sensor, stable wavelength calibration technology can spectral scanning reliability. Fuzzy theory, the components of rice taste, including viscosity, hardness, taste, aroma and so on, are evaluated and combined with near-infrared spectral data, and the taste score of the variety can be determined by measuring the uncooked rice sample.

3. use characteristics

1, evaluation, instead of artificial taste taste value

2. The analysis is fast, less than 40 seconds from the feed to the result display, and multiple indicators can be quickly detected

3, the sample does not need sample preparation and pre-treatment process, to avoid the error caused by manual and pre-treatment conditions.

4. The operation is simple and convenient, and can be used by any personnel; while the chemical and sensory methods require training of operators to carry out

5. The accuracy of the instrument meets the requirements of near-infrared instruments for moisture, protein and other detection indicators, and meets the requirements of GB/T 24895, GB/T 24896 and GB/T 24897

4. technical characteristics

1. The use of fixed grating spectrometer, internal optical system, stable spectral data acquisition.

2. With automatic wavelength correction function, the system automatically corrects before each measurement.

3. After feeding, the sample is automatically divided and measured to eliminate the influence of uneven samples on the data results.

4. The instrument has automatic diagnosis function and will prompt the wrong operation.

5. The built-in printer can print out the results.

Technical characteristics of 5. software

1, the use of inspection line, built-in japonica rice, japonica rice brown rice, indica rice rice, indica rice brown rice four data models.

2. Embedded computer system, using general windows system, convenient data statistics and reading, control and data communication through USB, plug and play.
