Extrusion and conditioning apparatus

摘要

An extrusion and conditioning apparatus, with an extruder in a conveying position, leads into a conveyor housing connected in a sealed manner to a pneumatic supply line and to a pneumatic conveyor line in which extruded material can be removed pneumatically, by means of superheated steam, via the conveyor line. The extruder can be moved from the conveying position into a bypass position, in which the extruder leads to the exterior of the conveyor housing, having a means for sealing the supply and conveyor lines and the conveyor housing from the surroundings when the extruder is in the conveying and bypass positions.

主权项

1. An extrusion and conditioning apparatus comprising:
a conveyor housing having a conveyor line, a centrifugal cyclone separator, a blower and a supply line arranged in series within a circuit with the conveyor housing to form a closed conveyor circuit filled with superheated steam at a temperature of more than 100° C. whereby the superheated steam absorbs moisture as the moisture gradually emerges from an extruded product within the closed conveyor circuit; an extruder having a plate abutting the conveyor housing, the conveyor housing being displaceable in a transverse direction along the plate, whereby a seal is maintained when the conveyor housing is moved between a conveying position and a bypass position on the plate without having to interrupt a circulating flow of steam and without air entering the conveyor circuit or steam escaping from the conveyor circuit; whereby extruded material is removed by means of superheated steam via the conveyor line and the conveyor line communicates with a centrifugal cyclone separator for discharging an extruded product; and the plate prevents ambient air from entering the closed conveyor circuit and steam escaping from the closed conveyor circuit when the conveyor housing is moved between the conveying position and the bypass position in order to remove material from the extruder in the bypass position.
