A process and apparatus for drawing off deformable masses containing air, such as sausage masses. The mass is transferred in a stream from a supply space into a filling cylinder where a vacuum is generated relative to the space to remove air from the mass, and the transferred mass is then ejected from the filling cylinder by means of a piston. To transfer the mass quickly and remove air from it completely, the mass stream is guided, during its transfer into the filling cylinder in such a way that, as it enters the filling cylinder, it first moves towards the cylinder wall at an angle to the direction of the piston. Moreover, during filling the level of mass in the filling cylinder is maintained at an essentially constant filling height so that a constant volume of free space remains above the mass in the filling cylinder.
In a process for drawing off deformable masses containing air in which the mass is transferred in a stream from a supply space into a filling cylinder where a vacuum is applied to the cylinder to remove air from the mass and in which the transferred mass is then ejected from the filling cylinder by a piston arranged in it, the improvement comprising drawing the mass into the top of the filling cylinder from the supply space by continously enlarging the filling cylinder by moving the piston away from the supply space to generate a vacuum inside the cylinder, deflecting the mass as it first enters the top of the filling cylinder towards a wall of the cylinder and at an angle to the shifting direction of the piston, and maintaining an essentially constant height of mass in the cylinder during filling, so that, during filling, an essentially constant volume of free space remains above the mass in the filling cylinder.
Apparatus for drawing off deformable masses containing air from a supply of mass and ejecting it in meterable quantities comprising a filling funnel for holding a supply of the mass, a filling cylinder having a piston arranged therein and connected to the filling funnel via an inlet orifice in the top of the cylinder, means for reciprocating the piston toward and away from the funnel whereby movement of the piston away from the funnel generates a vacuum in the cylinder for drawing mass from the funnel into the cylinder in the shifting direction of the piston, a slide for regulating the opening of the orifice and an outlet orifice in the cylinder through which mass in the cylinder can be ejected by shifting the piston toward the funnel, said inlet orifice being located and shaped so that it deflects the mass stream passing through it from the funnel to the cylinder toward and against a wall of the cylinder at an angle to the shifting direction of the piston, means for drawing a vacuum in the filling cylinder to remove air from the mass, means for sensing the level of mass in the cylinder during the filling of the cylinder and of the inlet orifice and/or the stroke of the piston to maintain an essentially constant volume of free space above the level of mass in the cylinder during filling.
