Powdered materials are often used in various industries. So, low shear and high-speed conveyance with at a low temperature (Heat is not generated) is required. In previous study, we developed a transport device based on the intestinal tract and demonstrated successful transport of the highly viscous and solid-liquid mixed fluids. In addition, it is possible to convey some powder by peristaltic device. In this paper, we developed a tubular peristaltic conveyor that improved shape of the conduit and the chamber for high-speed powder conveyance.
