A method and system reprocess soiled animal bedding material commingled with animal manure. In one aspect the soiled animal bedding material is separated in a shaker to send at least a preponderance of said manure to a holding tank. In another aspect the bedding is cleaned, rinsed and color is restored. Said bedding material is subsequently dried and a bedding product, fertilizer product, and/or compacted product is formed. Alternatively, said bedding material is dried (without a compacting step) to form a product. In another aspect, the steps of separation, cleaning, rinsing and/or color restoration may be omitted.

A vertical packaging machine for packaging products is provided that includes a forming element with an upper mouth and a hopper upstream of the forming element. At least the hopper and the forming element form a conduit through which the product falls. A flow generator includes an injection device for injecting a gaseous fluid through a distributor for directing the fluid to the conduit. The distributer has an inlet mouth for receiving the gaseous fluid and an outlet mouth with an area smaller than the area of the inlet mouth. The injection device is controlled by a control device that is configured to cause the injection device to perform an injection for each product to be packaged in one and the same package, the start and end of which depend on the position of the product with respect to the upper mouth and the outlet mouth.

A machine for manufacturing pouches containing a cohesionless material, including feed means for feeding the cohesionless material to a pick-up station, a transfer drum by which the material is picked up at the pick-up station and transferred to a release station, delivery means operating at the release station and by which portions of the material are delivered from the transfer drum through a duct toward a wrapping station at which the portions are sealed in pouches, and a mixer located at the pick-up station for performing a mixing action on the material at the pick-up station before the material is picked up by the transfer drum.

A system and method for dispensing a powdered pharmaceutical into a bottle is disclosed. The system includes a filler having a powder filler head and respective weight sensor, two or more draft shields, and one or more static reduction devices. In some embodiments, the system also includes one or more dust extractors. In some embodiments, the static reduction device is an active static reduction device, such as one or more static bars. The two or more draft shields may include an inner draft shield to reduce small pressure and/or airflow changes and an outer draft to reduce large pressure and/or airflow changes.

A hopper system for powder material includes a hopper and a cover. The hopper has hopper sidewalls that extend downward from an upper end of the hopper with at least one of the hopper sidewalls being sloped along a portion thereof. A hopper axis extends vertically between at least some of the hopper sidewalls. The cover is disposed at the upper end of the hopper and includes an opening configured for the powder material to flow therethrough and into the hopper. The opening defines a vertical material loading axis that is offset relative to the hopper axis. A diverter member may be provided that is positioned along the material loading axis and configured to divert the powder material entering through the opening. A powder material feed system may be disposed adjacent the lower end of the hopper to feed the powder material from the hopper.

A device for the metered filling of a drinking straw with a filling material includes a material store as a storage container for the filling material. An opening is present in the base of the material store, the opening discharging from above into a compressed air channel. A closure device is provided for sealing the compressed air channel relative to the material store. At least one receiving unit is present for receiving at least one drinking straw, so that the at least one drinking straw is able to be positioned with its upper edge region on the end of the compressed air channel on the air outlet side.
