Screw Feeder Flow Profile of Agro-Food Bulk Solids. Laboratory Stand Review

Abstract

Handling of bulk solids in agriculture and the food industry often involves the use of screw feeders. These are suitable for a wide variety of bulk solids materials with various physical-mechanical characteristics. In the food industry, it is important to control material flow and the behavior of the screw feeder affects the characteristics of the feeding hopper. Another key parameter is the amount of time that the material remains still in the bunker because the properties of the material are time-dependent. The experimental stand presents the discharging profile of screw feeders with variable geometrical design.
