Abstract
The present invention relates to a vane assembly for use in a drying apparatus comprising a drying chamber with a heating jacket which is used for drying moist material such as fish offal, food leftovers etc. The drying chamber is substantially cylindrical and has in the preferred embodiment a conical shape with a very small angle. In one embodiment the vane assembly can be employed in a substantially cylindrical drying chamber with straight side walls. The vane assembly is further suited for a drying chamber where the moist material is fed in at the bottom of the drying chamber, either from below, up through the bottom, or from above, through a pipe connection or the like down to the bottom of the chamber, with the result that the supply of the moist material is near the bottom of the drying chamber.
Claims18
A vane assembly for use in a drying chamber, said drying chamber being substantially cylindrical with straight or conical side walls, which drying chamber is provided with a heating jacket around at least part of the walls to heat the walls on the inside of the chamber, in which jacket a heated medium circulates, which drying chamber further has a supply opening for moist material, an outlet opening for dried material and an opening for expelling moist air, in addition to which said vane assembly is mounted in the drying chamber on a driven shaft extending along the drying chamber's cylinder axis, said vane assembly being mounted for rotation in a given direction about the cylinder axis, along the circumference of which vane assembly there are provided oblique, plate-shaped elements which raise the material from the vane assembly towards the upper area of the drying chamber, characterized in that said vane assembly is provided with one or more guide surfaces formed at an angle relative to the vane assembly's plane of rotation and extending substantially from the center of the vane assembly towards the outer edge of the vane assembly, and said vane assembly further comprises at least one scraping body that is inclined downwardly in the given direction for moving the material from the underside of the vane assembly to the upper side of the vane assembly.
