A multi stage auger system providing removal of air and void spaces from semi-solid materials is provided that includes a motor (13) coupled to an auger drive shaft (14) and an electrical control panel (3) with a product hopper (12) with a first diameter opening tapering to a second smaller diameter opening and coupled to an auger tube (18) at the second smaller diameter opening. An auger entry spiral (15) with a generally helical shape and an at least one sweep arm (16) coupled to the auger entry spiral and driven by the motor, the auger entry spiral and the at least one sweep arm skimming inside the product hopper to entrain the semi-solid materials from the hopper wall and, through the helical shape of the auger entry spiral, moving the semi-solid materials through the hopper from the first diameter opening towards the second smaller diameter opening in an auger entry area within the hopper. During this entrainment and movement by the auger entry spiral and at least one sweep arm there is a space left between the auger entry spiral and the at least one sweep arm to remove air and voids from the semi-solid material through the entrainment and movement. The auger (11) coupled to the auger entry spiral (15) and the at least one sweep arm (16), the auger having a first section with a first coarse pitch (15.2) providing further removal of air and void spaces through movement and agitation and a second finer pitch (15.3) providing a further movement under higher pressures near an exit of the auger tube and a die member is also coupled to the exit of the auger tube.
