Analyzer for cereal and oil plants and working method thereof

Abstract

The invention provides a portable cereal analyzer, comprising a light source, a detector and an analysis unit. The analyzer further comprises the following parts: a detecting probe, which comprises a pointed portion and a matrix portion, is used for being inserting in cereal; at least an emitting fiber, wherein, one end of the emitting fiber is connected with the light resource, and the other endis arranged on the detecting probe; and at least an incident fiber for receiving the reflected light obtained by reflecting the light emitted by the emitting fiber by the cereal and transmitting to the detector, wherein, one end of the incident fiber is connected with the detector, and the other end is arranged on the detecting probe, The analyzer can detect the internal portion of the cereal, and has the advantages of convenient operation, high automation degree and the like.

Description

technical field [0001] The invention relates to a grain analyzer, in particular to a grain and oil analyzer with a measuring probe that can be inserted into the grain or oil to be measured and a working method. Background technique [0002] Bulk grain and oil commodities such as soybeans, rapeseed, wheat, and corn urgently need rapid detection technology for quality parameters in the process of purchase, storage and transportation. Due to its fast, accurate and efficient characteristics, the near-infrared spectroscopy analysis method can meet the analysis requirements of grain and oil. [0003] At present, in the research and application of near-infrared detection technology for grain, laboratory-type near-infrared analyzers are generally used to carry out work, such as the Infratec1241 analyzer produced by FOSS Company in Denmark, the DA7200 analyzer produced by Perten Company in Sweden, and the PE Company in the United States. The SPECTRUM ONE NTS Fourier transform near-i...

Problems solved by technology

[0004] The Chinese patent with the publication number CN201788147U proposes a light-transmitting optical fiber measuring probe-type soil nutrient tester. This type of instrument is only suitable for liquid detection and cannot meet the requirements for solid detection.

The Chinese patent application number CN200720093240.6 discloses an ethanol gasoline optical fiber photoelectric analyzer for detecting ethanol gasoline components. The probe is used to detect liquid components and is not suitable for detecting agricultural products; A hand-held near-infrared measuring probe and detection method for non-destructive testing of the internal quality of fruits. Although the device is suitable for the detection of solids such as fruits, it cannot be inserted into the interior of the measured object for detection

The Chinese patent with the publication number CN101055245A discloses a portable soybean analyzer. Specifically, soybeans after traditional sampling are loaded into the portable analyzer for detection, which cannot meet the requirements of on-site detection without sampling.

The Chinese patent with the publication number CN1284164A discloses a grain quality detector, which is installed on the harvester to facilitate online detection equipment during grain harvesting. Although the equipment can detect in real time, it cannot meet the needs of bulk grain inspection.

The Chinese patent with the publication number CN101387605A discloses a fiber-optic type farmland soil organic matter content rapid detector, specifically an analyzer that can be inserted into the soil for detection. The analyzer has a tapered optical fiber probe, but the probe adopts a Y-shaped The optical fiber is used for detection, the light spot is small, and it is only suitable for point detection, so the detection representativeness is poor, and the measurement error caused by the unevenness of the sample cannot be eliminated.
