Patent attributes
A cartridge fluid filling system and method for the cannabis and hemp industry. The system comprises a gas-pressurized sanitary reservoir sub-assembly holding material to be dispensed. A spool valve sub-assembly lies in fluid communication with the reservoir sub-assembly and has a spool valve that moves to permit or block fluid flow to a metering rod. Effluent material may pass through an outlet port to a tray sub-assembly for locating cartridges into which metered amounts of the effluent material may be delivered. A robot moves a tray and the outlet port so that material is delivered in precisely metered amounts to cartridges in the tray without waste and in the absence of air bubbles. A human-machine interface includes controllers that supervise related process parameters.
