A compressor arrangement for automatically compressing ground coffee includes a housing having an inlet opening and an outlet opening with a retention flap which adjusts a bulk density of the ground coffee, conveying and compressing elements arranged in the housing which are driven by a first drive device, and an adjustment device which pre-adjusts the bulk density of the ground coffee. The adjustment device includes a second drive device, a retention flap shaft, a retention flap arranged on the retention flap shaft, a transmission which is operatively connected to each of the second drive device and the retention flap shaft, and an automatic dynamic pressure adjustment apparatus which enlarges or reduce a preset of the opening angle dependent on a higher dynamic pressure or a lower dynamic pressure being exerted on the retention flap. The transmission includes a transmission device which limits an opening angle of the retention flap.

Improved bales may be formed using methods that include using baling equipment with an air blasting crumb chute that may reduce wear and tear and maintenance, and/or improve efficiency by reducing material waste, imperfections, and/or contamination. The crumb chute may include an air inlet and a plurality of apertures in fluid communication with the air inlet. Air may be provided through the apertures to prevent crumbles from accumulating on the baling assembly as they fall through the chute to the press chamber and/or to blast already accumulated residual crumbles from components of the baling assembly, such as a traveling chute, and into the press chamber. The crumb chute may include a polyoxymethylene insert in which the air inlet and apertures are provided. The crumb chute may be provided as a kit for attachment to various baling apparatuses. Additional features and components also are described.

A press for waste has an actuator (42) that moves a ram (40) in a chamber (30). The actuator and the ram are connected by a fastening system (100). The fastening system allows the ram to be displaced in a direction perpendicular to the length and direction of travel of the actuator. In this way, as inner surfaces of the chamber wear the ram may adjust to the worn surfaces without applying large forces perpendicular to the length of the actuator. When the actuator moves forward, it pushes directly against the back of the ram. When the actuator moves backwards, it pulls a pin (102) that pushes on an inner surface (108) of the ram.

An agricultural baler. The agricultural bailer includes a baling chamber, a first plunger, a second surface opposing the first plunger, and a track assembly. The baling chamber includes a first wall and a second wall. Each of the first wall and the second wall includes a slot extending along a length of the baling chamber. The first plunger is moveable within the baling chamber and is configured to compress a compressible material into a bale. The second surface is configured to support the compressible material within the baling chamber. Each of the first plunger and the second surface includes a slot aligned with the slots of the first wall and the second wall. The track assembly includes a gated channel and is disposed within the slots of the first wall, the second wall, the first plunger, and the second surface such that the track assembly substantially surrounds the baling chamber.

A landscape product includes a compressed mulch tile having a top surface, a bottom surface, and a height between the top and bottom surfaces. The compressed mulch tile is made from loose mulch that has been dried, compressed and adhered together. A sheet of landscape fabric is adhered to the bottom surface of the compressed mulch tile.

A baling press with a bale pressing channel, a ram for pressing material in the bale pressing channel, the ram having a pressing face and a slot in the pressing face, a tying assembly on a first side of the bale pressing channel with a loop supply member for forming a loop across the bale pressing channel and movable between an extended position projecting through the slot and a retracted position. The press further has a slot clearing member movable between an extended position projecting through the slot and a retracted position on one side of said bale pressing channel. The slot clearing member and the tying assembly are on opposite sides of a feeding passage. The bale pressing channel is open for discharging cleared material on a side opposite of the location of the slot clearing member in its retracted position. A method of operation is also described.

A hydraulic compactor configured to be fastened to the cover structure of an underground collection container, for compacting waste materials. The hydraulic compactor includes a filling opening equipped with a hatch, via which the waste material may be entered into a compressing space inside the compactor, a press member being provided above the compressing space and being movable in the vertical direction inside the compactor. The press member presses the waste material fed into the compressing space against the bottom plate of the compactor. The bottom plate of the compactor is a hydraulic bottom plate opening in the horizontal direction, via which the waste material compressed in the compressing space is dropped into the underground collection container. The present disclosure also relates to an underground collection container comprising a compactor.

A press for processing organic waste has two plungers. Preferably, the plungers have rectangular cross sections. The two plungers are mounted in the press such that they are perpendicular to each other and have partially overlapping stokes. The press has walls that partially enclose a pressing chamber. The pressing chamber is as wide as one plunger on one side, and as wide as the other plunger on another side. In operation, one of the two plungers is used to optionally load organic waste into the pressing chamber, to partially enclose the pressing chamber while the waste is compressed, and to eject compressed waste from the pressing chamber. The other plunger is used to compress waste in the pressing chamber whereby a pressate is produced through perforations in a wall of the pressing chamber. The other plunger may also partially enclose the pressing chamber while compressed waste is ejected.

A compressor arrangement for automatically compressing ground coffee includes a housing having an inlet opening and an outlet opening with a retention flap which adjusts a bulk density of the ground coffee, conveying and compressing elements arranged in the housing which are driven by a first drive device, and an adjustment device which pre-adjusts the bulk density of the ground coffee. The adjustment device comprises a second drive device, a retention flap shaft, a retention flap arranged on the retention flap shaft, a transmission which is operatively connected to each of the second drive device and the retention flap shaft, and an automatic dynamic pressure adjustment apparatus which enlarges or reduce a preset of the opening angle dependent on a higher dynamic pressure or a lower dynamic pressure being exerted on the retention flap. The transmission comprises a transmission device which limits an opening angle of the retention flap.

A compaction system includes a compaction cavity having an inlet opening sized to receive a bag containing liquids and solids, and a compaction ram movable within the compaction cavity to compact the bag. At least one of the compaction cavity and the compaction ram includes at least one piercing member arranged and configured to puncture the bag to permit release of the liquids from the bag. The released liquids are collected with a liquid collection member.
