Quality control of cereals and oilseeds begins with taking the sample for analysis correctly. Sample is taken by automatic probe at a minimum of three sample points in vehicle which brings cereals to the analysis. If for some reason it is not possible to take sample by an automated probe, it can be taken by a hand held probe as well.
When sampling, it is important to pay attention to the representativeness of a sample. Afterwards one part of a representative sample is placed into quartering device, and the other part in Dickey John automated moisture and test weight analyser.
After that a certain amount of cereals is taken for analysis of admixtures which are determined by sieving through the sieve determined for that culture.
During the quality control of apples only healthy apples without presence of pests or damage caused by pests are being classified.
The class of apples is being determined by classification and they are sorted into extra class, class I and class II. All apples which are being classified must be typical for variety by shape, size and colour.
Damaged apples are not being classified, and those below class II are considered as industrial apples and are used for obtaining various apple products.
