MATHEMATICAL MODEL FOR DETERMINATION OF LOSSES OF SUGAR BEARING- MASS WHEN SUGAR BEET TOPS ARE REMOVED

Production of sugar from sugar beets is an important branch of agriculture and food industry in many European countries. In spite of the great progress, the contemporary root crop top removing machines cause considerable losses of the sugar-bearing mass and do not meet the agrotechnical requirements. When the tops are removed without a top feeler, a part of the root crop is cut off together with the tops. The removal quality of sugar beet tops during harvesting affects the amount of losses of sugar. A model has been developed for the determination of the losses of the sugar-bearing mass depending on the statistical characteristics of the height of elevation of the sugar beet heads from the ground and the density of the root crops. If the values of the statistical characteristics of height elevation of the root crop heads and their density are extreme, the losses of the sugar- bearing mass exceed the agrotechnical requirements two times.
