Title : An attempt to determine the influence of mixing time on the amount of impurities in compound feeds
Key words : feed mixture, fodder mixing plant, feed production, impurities
Summary :

The scope of the work included conducting research experiments for compound feeds with 8, 12 and 14 ingredients for various mixing times: 20, 30, 40, 50 and 60 minutes. The objective of the paper was to determine whether there are statistically significant differences between the amount of the received waste in the final product and the mixing time equal to 20, 30, 40, 50 and 60 minutes. Moreover, the amount of impurities in the product depending on the kind of the compound feed and mixing time was analyzed. By means of the Kruskal-Wallis test, significant differences between the expected values of the percentage shares of impurities for mixing times of 20, 30, 40, 50 and 60 minutes were proved and the varying pairs were given. Simultaneously, no significant differences between the distribution of probability distribution functions of the percentage shares of impurities in all compound feeds for 20 and 30 minutes of mixing were proved. Therefore, it is possible to shorten the mixing time from 20 to 30 minutes without decreasing the quality of the product. Moreover, a conclusion was made that the more ingredients are present in the compound, the bigger percentage share of waste is observed in the final product.
