Click the item "Whole" of the "Image" menu. Sorting 12) The filters in S21 are logical structures that apply to any processed sample to find the indexes of industrial quality of the sample. The results are used to calibrate the industry, keeping a standard of rice quality, from the arrival till the final product. In research centers, the filters allow to evaluate the physical characteristics of rice. The S21 works with two groups of filters: "Basic Filters" and "Advanced filters". To access them, a sample must be open. We will begin by explaining Basic Filters, but before accessing them read the box on the next page. Sorting Basic Filter Advanced Filters AGROMAY SOLUCIONES TECNICAS, S.L. C/. Los Yebenes, 71. 28047. Madrid. SPAIN Tel: +34 91 5099900 Email: [email protected] www.agromay.com pg. 8 TKD Tecnologia rice statistical analyzer Individual Characteristics of Grains Before starting the use of filters, it is necessary to understand how the S21 processes the samples. After processing the images coming from the scan, the S21 individualizes the grains found in the images with the following physical characteristics: Length, Width, Chalk Area, Spotted Area, Total Whiteness and Vitreous Whiteness. Click on a frame (grain) of the screen and see the individual characteristics of the selected grain. The S21 analizes one grain at a time. When there are two or more grains in the same frame, always consider the grain at the center. See the example below. 1 AGROMAY SOLUCIONES TECNICAS, S.L. C/. Los Yebenes, 71. 28047. Madrid. SPAIN Tel: +34 91 5099900 Email: [email protected] www.agromay.com pg. 9 TKD Tecnologia rice statistical analyzer Basic Filters The Basic filters are simple logical structures and easy to use. Its filtering logic is simple and gives the S21 user a quality profile of the sample that fits perfectly in the industrial classification process of rice. To continue the explanation, we will use the same sample as an example: "Diversos - Long White Thin - Harvest Rice". 01) Click Basic Filter. Sorting 02) This screen shows the list of basic filters available. Has four basic filters created, but you can create as many filters as needed. To apply or edit a filter, select an item from the list. In this example, as we have a sample of Long rice type, choose the filter "Long White Rice". AGROMAY SOLUCIONES TECNICAS, S.L. C/.

SPAIN Tel: +34 91 5099900 Email: [email protected] www.agromay.com pg. 10 TKD Tecnologia rice statistical analyzer 03) The box will expand showing the saved parameters in the filter. These parameters define with what criteria (chalk, spoted, length and width) that rice will be analyzed. The box at the bottom of the page has information about these parameters. Now we proceed with the analysis. Click "Apply» Filter «Long White Rice». How it Works? This parameter of the Basic Filter defines the index of chalky grains in two levels: Chalky (grains with chalk area >= 70%) and Partially Chalky (grains with chalk area >= 50% and < 70%). These parameters are editable. This parameter of the Basic Filter defines the index of the grains with Color defects (will be considered grains with color defects those with spotted area >= 10.5%). This parameter is editable. This parameter of the Basic Filter, defines (in this example) the index of grains of Other Varieties that are not Long (will be considered "other varieties", grains with width between 2.5 mm and 3 mm). This parameter is also editable. Obs.: The checkbox "Active" has the function to enable or not the parameter of the filter. AGROMAY SOLUCIONES TECNICAS, S.L. C/. Los Yebenes, 71. 28047. Madrid.

Sorting From this stage of the analysis, the user can print the report with the results. However, before printing the report, will be showed some important additional features of the Basic Filter. 05) To improve visualization of the results, we can group the grains within their indexes.

Through this feature you can merge two types of analysis: Numeric (only the application of the filter) and Visual (sensory). The advantage of this hybrid process in relation to the conventional analysis (manual) is the quickness with which the analysis is done by S21. To show this feature we'll use as an example the "Partial Chalky" index that is in 3.81%. We will manipulate the grains visually by using the feature "Sorting + Drag and Drop grains". The partial chalk is a index with a high degree of subjectivity, it is impossible to visually differentiate, for example, a grain with 50% of chalk area of another that has 48% or 53% of chalk area. The human eye does not have this capability. Therefore, starting from the beginning of this subjectivity, we can move some grains visually and suit the results. AGROMAY SOLUCIONES TECNICAS, S.L. C/.

SPAIN Tel: +34 91 5099900 Email: [email protected] www.agromay.com pg. 14 TKD Tecnologia rice statistical analyzer See how to use the feature "Sorting + Drag and Drop Grains" in the S21: 01) Click the index "Partial Chalky" to see the grains found by the filter. The index is at 3.81%. Remember that we are manipulating the sample "Long White Thin - Harvest Rice". Sorting 02) Now click the index "Head Rice" to see the good grains. The index found by the filter is 82.43% Sorting AGROMAY SOLUCIONES TECNICAS, S.L. C/. Los Yebenes, 71. 28047. Madrid.

To quickly find them, we will use the Sorting feature. Click the "Sorting" menu and then click the "Chalky" item. With this command, we sorted the grains in the screen «Head Rice» from more chalk to less chalk. Probably the first grain on the top screen will have a little less than 50% of chalk area and decreasing in the sequence. These first grains were not considered "Partial Chalk" by being with the chalk area just below the value set by the filter, in this case the limit was set at 50%. Sorting With the sort feature from the S21, the search for grains with more chalky within the "Head Rice" screen will be fast and simple. Now the user can use the Drag and Drop Grains feature of the S21 to put the grains visually deemed partial chalk into the index "Partial Chalky". See how on the next page.

The S21 has its own scale of whiteness with range 0-200. The Total Whiteness is measured from the total mass of the sample. The Vitreous Whiteness is measured from the total mass of the sample discarding the part considered chalk. We use the Vitreous Whiteness as a polishing reference, because it has less influence of the amount of chalk present in the sample. To get an idea, whiteness 40 in Kett scale corresponds to 130 in the S21 scale. In most varieties of white rice, the Vitreous Whiteness should be between 120 and 127 after polishing.

Before proceeding with this example, it is important to note that in a sample, besides the broken grains, there are two classes of whole grains: a) Perfect Whole Grains - grains that after the hulling and polishing remains perfect, with no broken parts. Is also excluded from the perfect whole grain class the smallest grains, poorly formed due to external factors, such as lack of nutrients, moisture, light, etc. b) Whole Grains - are grains that are larger or equal to 3/4 of its total. Even if they are clipped will be considered whole. In most countries there are regulations that define the measures of integers, 3/4, 1/2 and 1/4 for each class of grain (long, medium, short). Later we will discuss how these classes work in the S21. As we already have seen earlier in the guide, the S21 show us the sample divided into 4 size groups: whole, 3/4, 1/2 and 1/4. The objective of this analysis is to know what is the average length of the Perfect Whole Grains present in the sample 'Long White Thin - Only Whole'. We should then eliminate from the sample by dragging to the trash, the whole grains that are not perfect. For this we use the "Trash" feature combined with the "Sorting" feature. In this sample, the screen of "Trash" shows the number of valid grains (1322) and grains in the trash (0). 03) Click the item 'Height' of the 'Sorting' menu.

The measurement is performed using reference samples with known values. There are two types of reference samples: A) Sample with known values of whiteness and chalk area percentage. B) Sample with known values of whole and Broken. Fine Tuning of Whiteness and Chalk First, lets give attention to the concept of adjustment of Whiteness and chalk. The S21 comes with one reference sample Whiteness and chalk. N o t e In principle, any samples already analyzed by the S21 can be a reference sample for calibration. When passing an old sample in the S21 it should present very similar values. Therefore, it is necessary to keep 1 reference sample to keep the S21 in the original calibration. The S21 is scheduled to ask the Fine-tuning every 60 samples or every 2 days. When prompted we proceed with Fine Tuning by a standard sample, with known values of whiteness and chalk area percentage.

The standard sample has a prerequisite that it be a prepared Crystalline Rice and polished with a soft cloth so that it is free of dust stuck in its surface. This way we guarantee greater stability in its characteristics. Fine Tuning: Is the operability of the S21 that adjusts the reference of reading Whiteness and Chalk. This reference is measured with the processing of the standard sample. The program checks the result of Total Whiteness and Total Chalk Area obtained in processing of the sample and compares it with the "real" value informed of the Total Whiteness and Total Chalk Area of the Reference Sample, then proceeds adjusting the reading reference of Whiteness and Chalk for the result become closer to the "Real", keeping the system always calibrated. Reading Reference of Whiteness and chalk: Is the standard calibration reference that the S21 needs for that the results of chalk and color damage keep within a single standard reading. The S21 has a own pattern that comes along with the factory standard sample, delivered along with the S21. Shelf Life of the Standard Sample: The stored reference sample has a shelf life of 60 days, since stored properly, away from light, heat and humidity. After 60 days you can change their characteristics that will result in the loss of the reference values of Total Whiteness and Chalk Area. You should always keep some reference samples stored with an expiration date updated. Therefore, it is necessary to replace the old samples by new standard samples. (See the next topic) How to make new reference samples? 01) Reserve a portion of approximately 60g of prepared crystalline rice with minimum of chalky grains and white center. The sample must to be completely free of impurities. Clean with a soft cloth until it is polished. 60g of polished crystalline rice. Cleaned with a cloth. AGROMAY SOLUCIONES TECNICAS, S.L. C/.

Take the average of the values and round it up. 04) Store the new standard sample with the rounded values of Total Whiteness and Chalk Area (write these values). Adjusting PPC Pixels Per Centimeter The parameter that defines the measure of the grain is called PPC (pixels per centimeter) which determines the relationship pixels per centimeter. This parameter can be changed (adjusted) by the user. The S21 gets the measure of length of the grain by the 2 pixels more distant from each other (diagonal) and the width by the 2 pixels more distant from each other, perpendicular to the length. The PPC value is calibrated by analyzing one sample with kown values of length and width. Each machine has its own value of "PPC". Once adjusted, it is no longer necessary adjustment.

SPAIN Tel: +34 91 5099900 Email: [email protected] www.agromay.com pg. 45 TKD Tecnologia rice statistical analyzer Classification Setup. By processing the images of the grains captured by the scanner, The S21 software divides the grains of the sample in 4 groups of size: Whole, 3/4, 1/2 and 1/4. The result presented after processing is defined by the configuration we choose when the software starts. The user can create as many configurations as necessary. These settings are associated with the class of rice we want to analyze, for example, long, medium and short. Each configuration, besides the name, has three parameters to be informed: 1) Maximum height (mm): this value defines what is the maximum length to be considered as a grain in the sample. Grains (particles) that are above this value will not be considered in the analysis. For example, if the varieties of the rice class long thin does not exceed 8.5mm in length, we will use a value slightly above: 8.7mm. 2) Maximum width (mm): the same logic should be used for the width. If the varieties of the rice class long thin, do not exceed 2.4mm in length, we use a value slightly above, for example, 2.7mm. However, it is very common that in a sample of long thin rice has a quantity of merge of varieties, for example, medium grains, which are larger, measuring up till 3.0mm. It is possible, by filters, to look for the wider grains. In this case we must increment the value of width of 2.7mm to 3.0mm. 3) Reference Measure (mm): This parameter defines how will be the results of whole, 3/4, 1/2 and 1/4. Generally each country has its own rules that defines the measures to be adopted. In Brazil, for the rice class long thin, the grain is considered "whole" the one that is greater than or equal to 4.5mm long, which corresponds to a value of 3/4 of Reference Measure. See the diagram on the next page. AGROMAY SOLUCIONES TECNICAS, S.L. C/. Los Yebenes, 71. 28047. Madrid.

In this example with the value of 6.0mm of Measure Reference, we will have: Will be considered whole grains those who possess length greater or equal to 4.5mm, that corresponds to the value of 3/4 of 6.0mm. Wholes Kernels 3/4 4.5 mm Reference Measure 6.0 mm Will be considered 3/4 those grains who possess length greater or equal to 3.0mm and less than 1.5mm long. 3/4 Kernels 1/2 3.0 mm 1/2 Kernels 1/4 1.5 mm 1/4 Kernels Will be considered 1/2 those grains who possess length greater or equal to 1.5mm and less than 3.0mm long. Will be considered 1/4 those grains who posses length less than 1.5mm long. How to Adjust the PPC? 01) Prepare a reference sample with approximately 50 grams, 90% whole and 10% broken. The broken ones should be large, coarse. Attention! This sample should be checked manually with a caliper. 02) Open the Classifier S21 software and choose the configuration according to the class of rice from the reference sample.

When in doubt, read the table of pages 46 and 47 about it. The value must conform to the criteria used in the reference sample. 04) Scan the Reference Sample and Process it. 05) After processing, see the percentage results of whole grains. This value should be close to the real result, the difference should not exceed 2%. If the difference is greater, check if the value of Reference Measure is correct, or contact our technical support.

In weight, the amount should be between 30-100 grams depending on the size of the grains to be analyzed. How do I keep the S21 calibrated? Passing a reference sample with known values, that is, a sample already analyzed by the S21. The system adjusts itself from these values. See page 41. When passing an old sample, the S21 should shows practically the same results. The percentage results in the S21 are not in weight? Yes, the S21 calculates the percentage weight by a projection of the grain volume x format x density conform the transparency of the grain. This calculation is very accurate. What is the durability of LED lighting? According to our supplier, the LED has a lifespan of 70.000 hours. How much disk space is occupied by one analysis? Approximately 10-15 MB, including data and storing images of each sample. What is the average time that the S21 uses to analyze one sample? To a sample of 70g, about 2 minutes. The analysis is done in four steps: Scan the sample / Process images / Apply the filter / View the report. Can I combine, in the S21, the numerical digital analysis with the visual analysis? Yes, through the feature: Sorting + Drag and Drop Grains. See in the page 14. What is the difference by the digital image analysis (numerical) of visual analysis (sensory)? The analise system by digital image was developed with the aim to simulate the industrial classification process that sorts and separates the rice by size, by area of chalk, by color damage and whiteness. The industrial classification does not put people to sort and separate the rice, the classification is done by equipment that analyze the flow until the end, by a simple, quick and objective way. The type of analysis done by the S21 is somewhat analogous to industrial classification process. The best way to calibrate the industry and determine the industrial yield of raw material that enters the industry is by digital analysis (numerical). Sensory analysis is more subjective, it has a greater variation of results against digital numerical analysis, it is also more time consuming. However, the sensory analysis can reach more complex results often needed to evaluate the rice. AGROMAY SOLUCIONES TECNICAS, S.L. C/. Los Yebenes, 71. 28047. Madrid.
