US Patent 11800890 Automated deposition of highly viscous fluids into thin-walled cylinders

Disclosed are systems and methods for automatic infusion of concentrate and distillate material into cigarettes or other containers. In one embodiment, a thermally-controlled infusion system is provided. The system can maintain a selected temperature of the concentrate material throughout the infusion process, using a two-stage approach. In a first stage, the concentrate material is pressure-fed to a dosing chamber. In the second stage, the concentrate material is pumped into an insertion cannula and into a cigarette or container. A revolver houses the cigarettes or containers and vertically transitions them to an insertion position, where the insertion cannula can infuse the cigarettes or containers.
