The dispenser disclosed herein serves a single serving of a powdered nutrient contained within a container having multi-servings of the powdered nutrient. The dispenser has a metering device that operates as a ball valve or guillotine to dispense a single serving of the powdered nutrient into a water container. The dispenser also has a support surface that can be lowered and raised back up in order to fit a water container under the metering device and a distal tip of the metering device into a mouth of the water container so that no powdered nutrient spills out of the water container during transfer of the powdered nutrient from the metering device to the water container.

Apparatus and methods are provided for controlling flow of a flowable material. The flowable material passes from a product supply through one or more valves which are coupled to a controller. The controller is also coupled to one or more sensors operable to generate a signal indicating whether flowable product is present or not present at a specific level within a container. The controller is programmed to operate the valves based on signals received from the sensors. The sensors may be associated with the feed container and used to control metering of flowable product out of the feed container, or they may be associated with a container and used to control filling of the container with flowable product.

An apparatus includes a fixed assembly and a reciprocating assembly. The fixed assembly includes a hopper, a first gas manifold, and a dispensing chamber, and the reciprocating assembly includes a channel assembly defining a channel conduit, a shield plate vertically aligned therewith, and a second gas manifold. The reciprocating assembly may move, in relation to the fixed assembly, to a first position to enable the channel conduit to be filled with bulk compressible material from the hopper, a second position to enable compressible material to be pushed from the channel conduit to the dispensing conduit and to be compressed in the dispensing chamber according to a first gas directed through the channel conduit by the first gas manifold, and a third position to enable the compressed material to be pushed out of the dispensing conduit according to a second gas directed through the dispensing conduit by the second gas manifold.

A powdery-material feeding device is configured to feed a powdery material to a compression-molding machine configured to obtain a molded product by filling a die bore with the powdery material and to compress the powdery material with punches. The powdery-material feeding device includes a detector configured to detect a biologically-originated foreign matter mixedly contained in the powdery material to be fed to the compression-molding machine, and a controller configured to control to remove the powdery material mixedly containing the biologically-originated foreign matter detected by the detector to avoid feeding of the powdery material mixedly containing the biologically-originated foreign matter to the compression-molding machine, or to control to stop the feeding of the powdery material to the compression-molding machine.

Filling unit for a manufacturing machine for the production of disposable cartridges for electronic cigarettes; the filling unit has: a cylindrical tank which is arranged horizontally, is mounted so as to rotate in a stepwise manner around a vertical rotation axis, is delimited, at the bottom, by a base disc having a circular shape, and is delimited, on the sides, by a cylindrical side wall; a feeding duct that feeds a flow of tobacco inside the tank; a plurality of groups of seats, each of which is obtained in the base disc and is adapted to receive and contain a corresponding dose of tobacco; and a transfer device which is arranged in a fixed position and cyclically transfers the doses of tobacco contained inside the seats of a group standing still.

A device (10) for dosing a powder, in particular a pulverulent pharmaceutical, having a storage container (24) which has a storage chamber for storing a stored quantity of the powder to be dosed, wherein the storage container has a dosing opening (32), wherein the device has a dosing control element which can be movably driven and which, in a closing position, closes the dosing opening and, in at least one freeing position, frees the dosing opening for the dispensing of powder from the storage container into a target container to be filled, wherein the device has a vibration means which sets the powder in vibration in order to assist with the dispensing of powder, wherein the storage container has two container parts which are movable relative to one another and which delimit mutually connected sub-chambers of the storage chamber and each store a portion of the stored quantity of powder, wherein a first container part (28) has the dosing opening and wherein the vibration means cooperates with the first container part and thus sets the portion of the powder that is disposed in the first container part in vibration, and wherein the vibration means is uncoupled from the second container part (30).
