Compressor arrangement for automatic compressing of ground coffee

The invention relates to a compressor arrangement for automatic compressing of ground coffee having a first housing (4) which has an inlet and outlet opening (12, 14), wherein there are conveying and compressing elements in the housing (4) which are drivable by means of at least one first drive device, wherein the outlet opening (14) has a storage flap (16) which serves to adjust the bulk density of the ground coffee, wherein there is an adjustment device (20) via which a preadjustment of the bulk density can be adjusted, wherein the adjustment device (20) has a second drive device (22) which is operatively connected to a transmission (28) which is operatively connected to a storage flap shaft (18) on which the storage flap (16) is arranged such that the transmission (28) has means (30, 32, 34, 36, 38) which enable a limiting of the opening angle of the storage flap (16) and wherein there is an automatic dynamic pressure adjustment apparatus (10, 40, 42) which, in the case of a higher or lower dynamic pressure being exerted on the storage flap (16), enables an enlarging or reducing of the preset opening angle.
