XHP-PSTB-1A Rice Taste Analyzer

The XHP-PSTB-1 Rice taste meter is a specialized instrument designed for assessing the quality of cooked rice. By subjecting rice—formed into a specific shape—to spectroscopic analysis via the reflection and transmission of near-infrared and visible light waves, the device employs optical principles to quantify sensory attributes such as "appearance," "hardness," "viscosity," and "balance." Furthermore, it serves as a measurement tool for determining the "Taste Value"—a comprehensive metric used to objectively evaluate the overall palatability of the rice. This instrument is primarily utilized in rice research and breeding, milling facilities, commercial rice cooking plants, and rice-based food processing factories for quality inspection and control purposes. By serving as a substitute for manual sensory evaluation, the rice taste meter offers distinct advantages: it is simpler to operate, exhibits minimal deviation, and provides objective results.

GB/T 24895、GB/T 24896、GB/T 24897

l Replaces subjective manual taste testing with objective, convenient analysis, thereby eliminating errors caused by human subjectivity.

l Results are displayed in less than 40 seconds from the moment the sample is introduced, allowing for the quick determination of multiple parameters.

l  Samples can be analyzed directly without any prior preparation or pretreatment, avoiding errors introduced by manual handling or variable pretreatment conditions.

l The instrument is easy to use and accessible to any operator; in contrast, chemical and sensory analysis methods typically require specialized personnel with extensive training.

l The instrument's accuracy meets the specific requirements for Near-Infrared (NIR) analysis regarding parameters such as moisture and protein content, and complies with the standards set forth in GB/T 24895, GB/T 24896, and GB/T 24897.

l Features a fixed-grating spectrometer with a completely stationary internal optical system, ensuring highly stable spectral data acquisition.

l Includes an automatic wavelength calibration function that performs a self-calibration prior to every measurement.

l Features four built-in calibration curves covering various rice varieties: Japonica polished rice, Japonica brown rice, Indica polished rice, and Indica brown rice.

l Upon sample introduction, the instrument automatically performs sub-sampling measurements to mitigate the impact of sample non-uniformity on the final results.

l Equipped with an automatic diagnostic system that provides alerts in the event of operational errors.

l Includes a built-in printer for the direct output and hard-copy documentation of results.
