A machine produces twisted paper for loose file packaging. The machine includes at least one auger to reduce a dimension, such as diameter, of paper as it is pulled from a roll. The material moves past the auger into a twisting assembly wherein the paper is twisted or rotated about a longitudinal axis of the machine inside a pipe or tube. The pipe or tube includes a cutout or interruption in the sidewall within which a wheel resides. The wheel grasps and advances the paper through the twisting assembly as it rotates. As the paper leaves the twisting assembly it is pulled or otherwise fed through an exist region and is cut into segments of small twisted pieces of paper. The twisted segments of paper are of suitable size for use as loose fill packaging.

A screw conveyor based fabric dyeing machine including a machine body inside which a screw conveyor including a conveying screw and a fabric support board is arranged and generally parallel to an extension direction of the machine body. Fabric moves through a dyeing tube arranged with the machine body to fall down onto the screw conveyor so that the fabric can be conveyed by the screw conveyor forward through the machine body to reach a guide roller and a nozzle to complete a cycle of circulation for subsequently re-entering the dyeing tube to be dyed therein. As such, water consumption can be reduced and dyeing performance is enhanced, achieving energy saving and carbon reduction, reducing contamination to the surroundings, and realizing green economy.

A screw conveyor to convey powdery material, in particular cement. The screw conveyor comprises: a transfer screw; and a trough containing the transfer screw; the trough being provided with an inlet section and an outlet section of the powdery material. The screw conveyor is characterized in that the screw comprises: at least a first screw portion having a first law of continuous variation of the pitches of the screw, which can be graphically represented by means of a first function having in at least one stretch a first derivative other than zero; and at least a second screw portion having a second law of continuous variation of the pitches of the screw, which can be graphically represented by a second function having in at least one stretch a first derivative other than zero. The first law of continuous variation of the pitches is different from the second law of continuous variation of the pitches.

A continuous motion position controlled in-line linear seamer allows a manufacturer or brewery such as a microbrewery to have high speed can seaming (attachment of lids to full cans of beverage) with a single compact, inexpensive, independent and repositionable seaming machine. The seaming is carried out in-line with production, and is done using a linear can path with no need for a large carousel. The motion is continuous because a variable pitch worm drive is constantly operating, driving cans at different speeds for different portions of the can path, including one portion of the path at which the can may remain motionless while being seamed.

A system for conveying pasty material through a conduit has an eccentric screw pump having a stator, a rotor that rotates in the stator, a housing with an intake port, and an output port connected to the conduit. A drive rotates the rotor and thereby draws the pasty material in through the intake port and expels the drawn-in material as a compressed-material strand into the conduit. A valve supplies gas pulses to the conduit at time intervals for separating the compressed-material strand into material plugs of limited length traveling through the conduit.

A screw conveyor assembly includes a first screw conveyor with a first housing and a first conveyor screw arranged therein, a second screw conveyor with a second housing and a second conveyor screw arranged therein, a transition housing to which the first housing and the second housing are connected forming a transition angle, and a runner disposed in the transition housing and arranged to conduct material being conveyed from the first conveyor screw to the second conveyor screw. The first conveyor screw is arranged upstream of the second conveyor screw. An additional conveyor element is disposed on a helix of the first conveyor screw, such that the helix is directly adjacent to the transition housing.

The present invention relates to a pyrolysis apparatus comprising a pyrolysis chamber have a first end and a second end, a feed inlet connected adjacent the first end of the pyrolysis chamber, a biochar outlet connected adjacent the second end of the pyrolysis chamber, and a gas outlet in fluid communication with the pyrolysis chamber. The pyrolysis chamber and feed inlet further comprise centreless screw conveyors. The present invention alleviates the problems associated with dust, oils and tars being present in the generated syngas. The present invention can also be used in a method of continuously processing biomass.

A poultry chiller includes a tank and an auger rotatably held in the tank. The auger includes a first auger section and a second auger section. The first auger section includes a first auger shaft and a first auger flight. The first auger flight includes a first helical portion on the first auger shaft and a first flight extension that extends away from the first helical portion. The second auger section includes a second auger shaft coupled to the first auger shaft and a second auger flight. The second auger flight includes a second helical portion on the second auger shaft and a second flight extension that extends away from the second helical portion. The chiller includes a hanger bearing assembly between the first and second auger sections and extending to an upper portion of the tank.

A conveying apparatus suitable for sturdy articles, in particular flattened plastic bottles or the like, in a recycling plant, has an upwardly moving continuous conveyor that includes a horizontal conveyor and a vertical conveyor connected to the horizontal conveyor, both conveyors having a tubular housing in which a respective conveying screw is rotatably mounted. The inner wall of the tubular housing of the vertical conveyor and the associated conveying screw have a vertical driver bar disposed therebetween, projecting radially inward from the tubular housing and spaced from the conveying screw by a distance (a). The driver bar has cutting teeth on its longitudinal edge located at least facing the conveying screw. Preferably, the driver bar is fastened in an interchangeable manner on the vertical tubular housing and has cutting teeth on both longitudinal edges.
