Abstract:
The invention relates to a screw press apparatus (1) comprising an outer casing (2) surrounding a screening tube (6a) with a plurality of liquid discharge holes, a slurry inlet port (3) at one end of the screening tube and a solids discharge port (4) at an opposite end of the screening tube, the screening tube housing an axially located auger (5), the outer casing (2) having a first opening in fluid communication with the slurry inlet port (3), a second opening in fluid communication with the solids discharge port (4), and a third opening (8) in fluid communication with the liquid discharge holes of the screening tube (6), a cleaning device (20) located between the outer casing and the screening tube, a device (10) for axially moving the cleaning device. The cleaning device (20) has a rigid co-axial liquid supply pipe (30) having at least one washing pipe (21, 22, 23, 24) at least partially surrounding the screening tube (6), each at least one washing pipe (21, 22, 23, 24) containing a plurality of nozzles (211, 221, 231, 241) facing the screening tube (6a). The screw press apparatus is especially suited for processing protein containing slurries, and in another aspect the invention relates to a method of producing a gluten product using the screw press apparatus.
Abstract:
For providing inline sterile freeze drying of a product containing solid matter and a solvent, such as water, in a plurality of trays accommodated in at least one trolley, a system comprises a filling station having an inlet end and an outlet end, or a docking station, a freeze storage, a freeze dryer unit, an emptying station having an inlet end and an outlet end, or a docking station, a plurality of trays adapted to be accommodated in at least one trolley.

Abstract:
The support structure (20) is used in a filter bag for filtering gas and has a plurality of tubular pipe elements (21-26) extending in the longitudinal direction of the filter bag. The tubular pipe elements are connected to annular elements (27) located at a distance from each other in the longitudinal direction. The annular elements (27) include elements formed by a number of parts (28), each part having two ends and extending between adjacent longitudinally extending tubular pipe elements (21-26).
