Utilization of post-production waste of potato pulp and buckwheat hulls in the form of pellets

The purpose of this research was to determine the influence of potato pulp content (15, 20, and 25%) in a mixture with buckwheat hulls and the variable mass flow rate of the mixture (50, 75, and 100 kg·h-1) on the following parameters: the density and kinetic durability of the obtained pellets, their heat of combustion, calorific value, and water activity. Increasing the pulp content in a mixture with buckwheat hulls from 15 to 25% and increasing the mass flow rate of the flow of the mixture from 50 to 100 kg·h-1 caused a reduction of the density and kinetic durability of the obtained pellets and a significant increase of the water activity and moisture content of the pellets. Increasing the pulp content in the mixture from 0 to 25% caused a slight reduction of the heat of combustion, from 19.44 to 19.09 MJ·kg-1, and calorific value (for dry matter of buckwheat hulls, and pellets from a mixture of buckwheat hulls and potato pulp).
