An apparatus and method for presenting various surfaces of particles within a sample to a sensor device is provided. More particularly, embodiments of the present invention provide a pair of concentric counter-rotating surfaces and a dividing member fixed radially therebetween so as to form a scanning chamber wherein sample particles are reoriented relative to the scanning field of an adjacent sensor device by the counter-rotation of the surfaces and the consequent recirculation of the sample particles through the scanning chamber.

The invention discloses an on-line detection device and an on-line detection method for the moisture content of a cereal from a combine harvester. The on-line detection device comprises a sampling box, a servo motor, a sensor, a single chip microcomputer and the like, wherein an upper thin plate and a lower plate of the sampling box can be opened or closed; the sensor is located inside the sampling box. When the on-line detection device works, the single chip microcomputer controls the servo motor to rotate, so that the upper thin plate is opened and the lower thin plate is closed, takes out a fixed volume of the cereal from a grain outlet by utilizing the sampling box, and then controls the servo motor to rotate, so that the upper thin plate is closed; the single chip microcomputer receives information from the sensor and carries out data processing to obtain the moisture content. After the measurement is completed, the servo motor is controlled to rotate, so that the lower thin plate is opened and the cereal freely falls into a grain box. Subsequently, the control is repeated to open the upper thin plate and close the lower thin plate, so as to carry out sampling detection of a next time; the on-line real-time detection is realized. A multi-information fusion technique is adopted by the on-line detection device and the on-line detection method; the influences of an ambient temperature and the density of a cereal pile in a detection process are eliminated; the detection reliability of the moisture content is improved.

The invention discloses a tobacco grouping method based on raw materials quality dynamic changes. The method comprises the steps that loosing and conditioning and thin plate drying are carried out on cigarette blending formulation raw materials to be grouped according to the same technology, and tracking and sampling are carried out on the raw materials before loosing and conditioning at the outlet of the thin plate drying procedure; the crush resistance and precursor-aroma compound content of the non-processed raw materials and the crush resistance and precursor-aroma compound content of the processed raw materials are detected; the change rate of the crush resistance and precursor-aroma compound content of the cigarette blending raw materials is calculated; clustering is carried out based on the changing rate of the crush resistance and precursor-aroma compound content of the cigarette blending raw materials, and the cigarette blending formulation is divided into two to three modules. According to the tobacco grouping method based on the raw materials quality dynamic changes, the tobacco raw materials are grouped according to the raw material quality change degree, the tobacco quality dynamic changes and raw material processing characteristics in the tobacco primary process are sufficiently considered, the grouping result is more scientific, more objective and more exquisite, sensory evaluation is not needed, the number of detection indexes is small, the detection method is easy to implement, the detection result is object and accurate, man-made subjective factor influences existing on sensory evaluation are avoided, and the grouping result is more reliable.

A method for presenting various surfaces of particles within a sample to a sensor device is provided. More particularly, embodiments of the present invention provide a method for presenting a sample comprising a plurality of sample particles to a scanning field defined by a sensor device, the method including directing the sample into a scanning chamber configured to contain at least a portion of the scanning field of the sensor device, subjecting the sample to different relative velocities, and redirecting the sample into the scanning chamber such that the plurality of sample particles of the sample are reoriented relative to the scanning field defined by the sensor device. In some embodiments, at least one trait of the sample is measured with the sensor device.

Apparatus, methods, and systems for useful sampling of seed, wherein viability is maintained, are disclosed. Seed from one generation in a plant advancement experiment is individually sampled by removal and collection of tissue from the seed using a hand-held and manually operated tool having one or more cutting edges. The tissue is then processed to derive one or more biochemical, genetic, or phenotypic characteristic of the seed before a decision is made whether to utilize that seed further in a plant advancement experiment or other plant research and development. In some embodiments of the method, the sampling is controlled to remove a useful amount of tissue for analytical purposes without significant effect on viability potential of the sampled seed. In some embodiments, the sampling is controlled to deter contamination of the sample. In some embodiments, the seed is held in pre-determined orientation to facilitate efficient and accurate sampling.
