Abstract: The invention concerns a method of processing eggshell residues, which emanate from an egg breaking unit (1) and comprise eggshell portions as well as membrane portions. The method comprises feeding of the eggshell residues into a cyclone (5), which is driven by a process gas having a temperature of less than 85° C. In said cyclone (5) vortex processing of the eggshell residues leads to peeling of said membrane portions off of said eggshell portions, such that said eggshell portions become separated from said membrane portions. A mix mainly of process gas, vapour and droplets is released through a top outlet (6) of said cyclone (5), whereas a mixture mainly of separated eggshell portions and membrane portions is released through a bottom outlet (7) of said cyclone (5). Finally in a sorting device (8) sorting of said released mixture is performed into an eggshell portion part and a membrane portion part.

Abstract: A method of drying solid biomass is disclosed. Particles of the biomass are first mechanically pre-dried by feeding them into a press. There they are partially split into fibers to increase their surface area, and liquid is squeezed out of them and from between them. The liquid is led away from the press. The mechanically pre-dried biomass particles are immediately fed out of the press into a process gas stream that entrains them and feeds them tangentially into a cyclonic processing chamber. In the chamber, the particles collide with themselves and with other solids that have been introduced into the chamber. The water and steam released by these collisions is led out of the top of the chamber, and the dried particles are led out the bottom.
