Devices, systems, and methods for depositing plant seeds are provided herein. Some embodiments include a seeder head device that includes a body having a proximal end and a distal end spaced a distance from the proximal end, a bore extending through an interior of the body from the proximal end to the distal end, a first hold arm disposed within the bore and coupled to a first actuator, and a second hold arm disposed within the bore and coupled to a second actuator. The bore includes a proximal opening at the proximal end and a distal opening at the distal end, and is shaped and sized to receive seeds at the proximal opening. The first hold arm and the second hold arm are movable to selectively allow one or more of the seeds to fall under force of gravity (or other force) to the distal opening of the bore.

In one of its aspects, the present invention relates to a process for forming a flexible liquid-packaging pouch. This process improves fill-accuracy of the flowable material contained in the pouch. Specifically, the invention relates to a process for improving the fill-accuracy of a pouch by incorporating at least one stand-pipe in a balance tank that feeds the pouch with flowable material to be packaged. This invention also relates to such apparatus for improving the fill-accuracy of the flexible liquid-packaging pouch.

A storage and dosing station for storage and dispensing dosed quantities of solid drug portions. A stationary part of the station is mountable to a frame of an apparatus for packaging solid drug portions, the stationary part including a first part of a dispensing device. The first part includes a controller and a drive for driving an individualizing mechanism for dispensing separate solid drug portions. A detachable part is coupled to the stationary part and includes a storage container for receiving a plurality of solid drug portions. A second part of the dispensing device includes an information memory. An information reader on the stationary part is coupled to the controller, wherein the information reader reads information stored in the information memory if the detachable part is coupled to the stationary part. The information memory stores data that are used by the controller to control the operation of components of the dispensing device.

A storage and dosing station for storage and dispensing dosed quantities of solid drug portions includes a controller, an information reading device coupled to the controller, a dispensing mechanism, a detachable storage container configured to store solid drug portions, an outlet configured to output the solid drug portions and an information memory. The information memory may store data that comprises one of a glossiness level of a surface of the solid drug portions and a reflectivity level of the surface of the solid drug portions that is used by the controller to control dispensing of the solid drug portions; that is used by the controller to adjust a sensor; and that comprises parameters of movement of the dispensing mechanism of one or more of maximum torque, rotation angles, and rotation positions of the movement of the dispensing mechanism used by the controller to control dispensing of the solid drug portions.

A pellet column is formed in a metering duct. The lowermost pellet is located in a connection point where an outlet duct is connected to the metering duct and leads transversely away therefrom. A first duct, which opens into the metering duct via a first duct mouth above the connection point, is impinged with negative pressure, wherein a pellet is suctioned onto the first duct mouth and is fixed thereto. This pellet acts as a block for the pellets thereabove. A second duct, which opens into the connection point via a second duct mouth, is impinged with positive pressure, wherein the pellet at the connection point is pneumatically ejected via the outlet duct and supplied to a container. After the ejection of the lowermost pellet, the negative pressure in the first duct is switched off such that the pellet held at the first duct mouth advances toward the connection point.
