The present invention relates to a pressing device for, in particular, long-stemmed plant material for providing a bale from the plant material, the pressing device comprising a pressing chamber with a pressing space to which plant material can be supplied by means of a supply apparatus via a supply opening, a pressing element movable from an initial position into an end position with a drive apparatus for compressing the plant material, and a binding apparatus, wherein the pressing space is delimited laterally by a wall for forming a pressing box, and an abutment delimits the pressing space, against which abutment the plant material is compressible during the movement of the pressing element into a first partial bale, wherein the first partial bale provided in this manner is transportable through a transport opening of the pressing space into a following space, wherein by means of the pressing element at least one further partial bale can be provided by compressing further plant material introduced into the pressing space against at least one abutment arranged at the pressing chamber, wherein the partial bales can be output via an output opening of the pressing chamber, and wherein the two or more partial bales can be joined by means of the binding device to form a final bale. The invention also relates to a pressing system and a method for providing a final bale with a pressing device.

The method or process described is directed at conditioning and packaging freshly chopped biomass such that it can be stored for a long period of time without spoilage and such that the packaged chopped biomass is easily transportable and its composition and other properties remain stable.

A method for pressing bales of material in a baler is disclosed. The method comprises the steps of feeding the material into the baler through an inlet, pre-compressing the material under a number of compressing cycles by a first press, transporting the pre-compressed material by a transport unit into a second press, and compressing the pre-compressed material by the second press into a finished bale of compressed material. The step of transporting the pre-compressed material by a transport unit into a second press is conducted in a space of the baler, such that an undesirable expansion of the pre-compressed material can be prevented. A baler for pressing bales of material is also disclosed.

A baling assembly can include a housing defining an interior, an access panel coupled to the housing and providing selective access to the interior, a baling chamber within the housing, and a ram adjacent the baling chamber. The ram includes a movable wall and a driving mechanism operably coupled to the movable wall for compression of material within the baling chamber.

Apparatuses for forming blocks of compactable material such as snow, having a hollow upper body with a compression chamber within for containing and subsequently compressing the compactable material to form a block that can be used in connection with recreational activities. A lower body having a flat compression plate attached to a top end, is configured to slide within the compression chamber, the compression plate being capable of pushing the compactable material into a hinged lid that is attached to a top end of the upper body and acts to cover a top opening of the upper body. Ferromagnetic materials attached to the underside of the compression plate are configured to contact other ferromagnetic materials attached to the interior walls of the compression chamber, which at least temporarily arrests sliding movement of the upper and lower bodies, and allows a user to fill the apparatus with compactable material.

A baling assembly can include a housing defining an interior, an access panel coupled to the housing and providing selective access to the interior, a baling chamber within the housing, and a ram adjacent the baling chamber. The ram includes a movable wall and a driving mechanism operably coupled to the movable wall for compression of material within the baling chamber.

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 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.

Improved balers may include a traveling chute that may reduce wear and tear and maintenance, and/or improve efficiency by reducing downtime. The traveling chute may include moving guides that include channels that engage tongues of stationary guide rails disposed on a baler. For example, the channels may be substantially rectangular channels that run the length of the moving guide. Similarly, the stationary guides may include substantially rectangular tongues and the moving guides may slide across the tongues and upper surfaces of the stationary guides as the traveling chute moves between various positions. The moving guides may include polyoxymethylene inserts in which the channels may be provided. The moving guides and stationary guides may be provided as a kit for attachment to various baling apparatuses. Additional features and components also are described.

The invention relates to a system (1) comprising a feeding device (2) comprising a channel (6) having an inlet (8) and an outlet (10) and a feed screw (12) for conveying biomass material through the channel. The feed screw comprises a screw flight (12b) that extends from a first end (12c) to a second end (12d) and is adapted to form a gas impermeable plug of biomass. The system comprises at least one primary measuring unit (14; 16) adapted to continuously measure a primary variable indicative of the gas permeability of the plug, which primary measuring unit is connected to said feeding device between the first end of the screw flight and the outlet; and a control unit (3) adapted to use said primary variable values to monitor the gas permeability of the plug. The invention also relates to a method for preventing blow back in the above described system.
