The invention relates to a device for preparing and applying adhesive, comprising a feed unit, a preparing unit, and an application unit, wherein the feed unit is used to feed a basic component of the adhesive and/or of at least one additive, wherein the preparing unit effects continuous mixing of the basic component of the adhesive with the one or more fed additives to form the prepared adhesive and continuous conveying of the prepared adhesive, wherein the adhesive prepared in such a way is conveyed from the preparing unit into the application unit and can be applied to a workpiece by the application unit.

The invention relates to a mixing and conveying system for dry mortar materials. The dry mortar materials can be obtained from a storage silo (1) through an openable closure panel (3). A pipe (17), in which a drivable screw conveyor (4) is mounted, is arranged under the closure panel (3). The pipe (17) leads into a mixing and buffer container (18), in which a coil (20) is rotatably mounted on a central axis (19). The mixing and buffer container (18) has a volume which equals at least 1.5-times the minute capacity of the pump-screw conveyor (14). It is thus ensured that the dry mortar material is mixed therein with the added water for at least 90 seconds or longer. The mixing and buffer container (18) leads into a pipe (15) at the bottom having a pump-screw conveyor (14) which conveys the mixed mortar into a hose (5). The pump-screw conveyor (14) can be allowed to run backward. The coil (20) runs continually such that the mortar is constantly agitated to prevent setting.

Embodiments relate to an insulation filling device for a fuel reformer, comprising: a feeder for supplying a powder insulation material; a stirrer for mixing the powder insulation material with a liquid binder for the agglomeration of the particles of the powder insulation material to form an insulation paste; and a thermal molding device for compressing said insulation paste to form a plurality of insulation molds having a predetermined shape and filling the insulation space of the fuel reformer with said insulation molds.
