Determination and use of rational parameters of the drying process of beet pulp when creating a drum dryer with a combined energy supply

Beet pulp is a secondary material resource obtained using traditional sugar production technology. Bagasse can be used as raw material for biogas plants, obtain biodegradable packaging, and as feed for livestock. Fresh bagasse has several disadvantages: short shelf life, difficulty in transportation, it is advisable to dry it to eliminate these shortcomings. To preserve the useful qualities of pulp, air with a low temperature is used as a drying agent. To study the interaction of various factors affecting the drying process of beet pulp, mathematical methods are used to plan the experiment. A mathematical description of this process can be obtained empirically. Moreover, his mathematical model has the form of a regression equation, found by statistical methods based on experiments. As a result of statistical processing of the experimental data, regression equations are obtained that adequately describe the drying process of beet pulp in an air dryer. As a result of the research, it was proposed to use a drum dryer with a combined energy supply (air and superheated steam), which will not only accelerate the drying process, but also preserve the useful qualities of the product.
