Can be supplied to the hopper 15 of the introspection quality measuring device 6 by the transporting means 22 of FIG. Therefore, the introspection quality measuring device 6 is configured to be able to measure the content and the like by the component analysis under the condition of brown rice and the component analysis under the condition of white rice.
[0013]
It is assumed that a predetermined volume of brown rice is introduced into the sample cell 14 by a predetermined rotation of the feeding valve 4b, and these are subjected to near-infrared spectroscopic analysis as they are. a configuration you supply and discharge to the weighing hoppers 24 of the weighing mechanism 23 of the load cell or the like. That is, the control unit 25 can calculate the brown rice weighing by the combination of the weighing signal from the weighing hopper 24 and the volume signal by the feed valve 4b, and these constitute the volume weight measuring means 26.
[0014]
The weighing hopper 24 of the volumetric weight measuring means 26 is configured to be able to receive the white rice put into the sample cell 14. The volume of the white rice is determined by the volume measuring means 27 provided in the middle of the path of the conveying means 22, and the volume measuring means 27 is configured as a delivery valve in the form of the delivery valve 4b.
27 'is a surplus particle discharge channel. The control unit 25 is configured to calculate a white rice bulk weight based on the volume signal and the weighing signal from the volume measuring unit 27 and display the white rice volume weight on the display unit 21.
[0015]
The brown rice and the white rice whose volume weights have been measured are supplied to the second sample packaging means 28. Second sample packaging means 28 is the first packaging means the same form, details are omitted, can be packaged continuously person the brown rice and white rice. The predetermined grain number measuring means 29 is, for example, a thousand grain weight measuring means, and the 3,000 sample bags 30 packed by the first sample packing means 9 are weighed by the weighing means 31 during the transfer of the discharge conveyor 11 and weighed. The signal is input to the control unit 25, and the signal is tared as appropriate and converted to a 1000 grain weight.
[0016]
Reference numeral 32 denotes a final conveyor, which is configured to be accommodated and stored for each same sample in a sample storage box 35 which waits downward in synchronization with the conveyor 34 for the discharged sample bags 33 from the second sample packaging means 28. Note that a slip (not shown) in which the person to be inspected, the product type, the date, and the like are printed out is simultaneously packed in the sample bags 30, 33, and the like.
[0017]
The operation of the above example will be described. When the brown rice sample A to be inspected is put into the hopper 1, the distribution device 2 distributes the brown rice A into approximately three equal parts. Among them, brown rice from the temporary storage tank 3a is supplied to the rotating disk 5a of the appearance quality measuring means 5 while being fed out by predetermined grains from the feeding valve 4a, and the appearance is detected by the optical detecting means while being scraped up for each grain. Based on the information, the control unit 8 determines whether the rice is good brown rice, immature grain, colored grain, dead rice or cracked body. The measurement of 1000 particles is performed three times , and the measurement of 3000 particles is performed three times , and the discharging means is operated to discharge each of them to a predetermined sorting / discharging position (not shown). At the same time , the ratio of each grain to the total number of grains is calculated and stored in the storage unit.
[0018]
One measurement of the appearance quality measuring means 5 takes about 60 seconds, and about 30 seconds for sample switching, which takes 4 to 5 minutes, during which time the sample A from the temporary storage tank 3b has a predetermined delivery capacity. It is secured by the delivery valve 4b and is charged into the ascending sample cell 14. When the sample cell 14 descends and reaches a predetermined position, near-infrared spectroscopy is performed. For example, the taste value, protein content, water content, etc. of the brown rice sample A are calculated based on a preset calibration curve, and these are also stored in the storage unit. The required time is about 60 seconds for one measurement, so that if the averaging process is performed three times, it is almost the same as the appearance quality measuring means 5.
[0019]
The sample A supplied to the whitening means 7 is subjected to whitening under a standard whitening pressure. Since the respective processes of the appearance quality measuring means 5, the introspective quality measuring means 6, and the refining means 7 are performed in parallel, a plurality of determination processes of the same sample A and handover to the next process can be quickly performed. Brown rice samples sorted by appearance quality measuring unit 5, the first sample packaging means 9 are respectively bagged disconnected in this the samples A units, are transferred to the conveyor 11. Thereafter, the weight is measured by the measuring unit 31 and a predetermined number of grains (thousand grains weight) can be measured.
[0020]
The brown rice sample A measured by the introspection quality measuring means 6 reaches the lowest position by the lowering of the sample cell 14 after completion of the measurement, where the opening / closing plate 14a is automatically discharged and the sample is transferred to the weighing hopper of the volume weight measuring means 26. 24. Based on the weighing signal Wg and the volume signal Vg obtained from the rotation of the feed valve 4b, the control unit 25 calculates and stores the brown rice bulk weight using Wg / Vg.
[0021]
While the brown rice sample A is supplied to the weighing hopper 24, the volume of white rice from the whitening means 7 is measured by the delivery valve 27 in the conveying means 22, and the white rice is put into the sample cell 14. Near-infrared analysis of white rice is performed, and in this case, for example, the same taste value, protein content, or moisture as those of the brown rice are measured.
Also, the volumetric weight is calculated for the white rice sample. The white rice sample is put into the weighing hopper 24 after the brown rice sample has already been discharged, and the weighing signal Wh and the measured volume Vh are used to determine and store the white rice bulk weight.
[0022]
The sample of brown rice and white rice ended the measurement of each volume weight, is bagged conveyed to a predetermined discharge position in conveyor 34 to the second sample packing means 28 is supplied form continuous. From the good brown rice ratio, the colored grain ratio, and the like, which were confirmed by the appearance quality measuring means 5, the brown rice bulk weight by the bulk weight measuring means 26, and the 1,000 grain weight obtained from the predetermined grain number measuring means 29 , the sample A was used as the brown rice inspection standard. which corresponds to the quality or can be determined. According to the introspection quality measuring means 6, a moisture value, a taste value, and the like can be obtained as reference information.
[0023]
In addition, various data can be obtained not only in the brown rice sample state but also in the white rice state, and the quality and quality in a state close to rice cooking can be obtained.
In addition, for example, the control unit 25 compares the ratio between the brown rice bulk weight and the white rice bulk weight with a preset value, and estimates that when the white rice bulk weight is higher than the predicted range, the generation rate of the crushed grains is high. For example, various values before and after the whitening processing conditions can be confirmed, and it is easy to be a guide to know the setting of the whitening processing conditions and the necessity of pre-humidification.
[0024]
In the above embodiment, since the brown rice sample used in the appearance quality measuring means 5 is used as the predetermined grain number measuring means 29, the number of sample grains that can be input as information for the purpose of determining the appearance of each grain is used to confirm the number of sample grains. Although it is possible to simplify the configuration, the present invention is not necessarily limited to this configuration. A separate counting means may be provided and the volume weight may be obtained by comparison with the weighing signal. The number of particles to be measured does not necessarily have to be a thousand, but may be a multiple or a fraction, or may be a fraction. Conversion is easy.
[0025]
In the embodiment, since the discharge brown and white rice from the sample cell 14 was form that can be measured is supplied to the volume weight measuring means 26, but simplified the supply path can be achieved, may be in the form that can be fed directly to the weighing means. In the above embodiment, only the brown rice sample is measured by the appearance quality measuring means 5, but the same processing may be performed on white rice. In this case, by knowing the appearance quality after the whitening treatment, it is possible to know the quality assurance or the whitening yield at the time of shipping white rice.
