An intermittent rotary machine for filling capsules with pharmaceutical or nutraceutical products is provided with a dosing disc, which delimits a hopper at the bottom for containing a pharmaceutical or nutraceutical powder product and has at least a group of dosing chambers, which are fed first of all through at least one compacting station, in the area of which the product contained in each dosing chamber is compacted by a respective compacting piston, and then through an expulsion station, in the area of which only part of the product contained in each dosing chamber is discharged into a respective capsule by a respective expelling piston.

A developer supply container includes a rotating container for conveying a developer and an intermittent regulator for intermittently supplying gas into the rotating container and regulating an internal pressure of the rotating container. A fixed amount of gas is intermittently supplied by the intermittent regulator to the gas mixing space and is discharged from the powder discharging port after the fixed amount of gas is mixed with the developer. Since the intermittent regulator can periodically supply the fixed amount of gas to the gas mixing space, the fixed amount of gas ensures a stable gas pressure inside the developer supply container. The developer supply container can continuously and stably replenish the developer into the image forming device under any storage or operating environment. The air pressure of the developer supply container is maintained at a stable level and a high precision replenishment amount of the developer is achieved.

Systems and methods for metering a granular material for packaging in pouches are disclosed. A system includes a hopper structured and arranged to hold a granular material in a hopper cavity. The system also includes a measuring system including a measuring cavity and a tube that is slidable in the hopper cavity between a first position unaligned with the measuring cavity and a second position over and aligned with the measuring cavity. The measuring system is structured and arranged to move a portion of the granular material from the hopper cavity to the measuring cavity when the tube is in the first position. The measuring system is structured and arranged to move the portion of the granular material from the measuring cavity to a pouch making machine using pressurized gas when the tube is in the second position.

An apparatus configured to provide portioned instances of a compressible material includes a channel assembly, a gas source, a cutting assembly, and a discharge assembly. The channel assembly holds a bulk instance of the material extending through upper and lower channels of a continuous channel. The gas source supplies gas to compress the bulk instance. The cutting assembly moves in relation to the channel assembly to isolate the upper and lower channels, severing upper and lower material portions of the bulk instance. The discharge assembly directs gas to impinge on a lower face of the cutting assembly to discharge the lower material portion as a portioned instance. The channel assembly may be moveable, where operation of the gas source, cutting assembly, and/or discharge assembly are based on moving the channel assembly between various positions. The gas supply may be controlled based on a determined property of the portioned instance.

A dosing station for a capsule filling machine comprises a dosing unit in which capsule lower parts are filled with a filling material via a filling apparatus and a drive unit with at least one drive that drives at least one component of the dosing unit. The drive unit is arranged beneath a supporting plate, and detachable fastening and coupling means detachably fastens the dosing unit on the supporting plate. Where the dosing unit is detachably fastened on the supporting plate, the at least one drive is coupled to the at least one component. In the detached state of the dosing unit from the supporting plate, the coupling of the at least one drive to the at least one component is canceled. In this way, the dosing unit can be removed as a module from the dosing station.

Described is a unit for filling containing elements (2) of single-use capsules (3) for extraction or infusion beverages, comprising: a line (4) for transport of containing elements (2) designed to contain a dose (33) of product; a station (SR) for filling the containing elements (2) comprising: at least a first containing seat (S1) designed to receive a dose (33); a substation (ST1) for forming a dose (33) inside the first containing seat (S1); at least a second containing seat (S2) designed to receive the dose (33) from the first containing seat (S1); a substation (ST2) for transferring the dose (33) from the first containing seat (S1) to the second containing seat (S2); devices (7) for moving the first containing seat (S1) between the forming substation (ST1) and the transfer substation (ST2) and vice versa; a substation (ST3) for releasing the dose (33) from the second containing seat (S2) to a containing element (2); further devices (8) for moving the second containing seat (S2) between the transfer substation (ST2) and the release substation (ST3) and vice versa.

A pipette for metering powder has a pipette sleeve and a metering piston having an end face for ejecting powder from the sleeve. The sleeve includes a free end and, on the sleeve inside, includes a circumferential wall extending in a closed manner around a longitudinal axis. The wall extends in the direction of the axis up to the free end and ends there in an edge which extends around the axis. The piston is guided to be movable parallel to the axis inside the wall. The end face, with the piston in a retracted metering position, defines a chamber with the wall. The wall is, in the region of the chamber, divided into a guide portion and a release portion adjoining the guide portion and extends up to the edge. The release portion surrounds a cross section of the chamber which is radially widened compared to the guide portion.
