PCT No. PCT/FR97/02468 Sec. 371 Date Sep. 2, 1999 Sec. 102(e) Date Sep. 2, 1999 PCT Filed Dec. 31, 1997 PCT Pub. No. WO98/29016 PCT Pub. Date Jul. 9, 1998A press for food products adapted to be reduced to a puree, comprising a working bowl (12) closed by a removable cover (21) and enclosing a rotatable press tool (23) comprising a central vertical shaft (27) which carries at least one pressing blade (30) whose external edge extends toward the lateral wall of the bowl (12), and which is coupled in rotation to a drive shaft (19) of a motor group by means of a coupling device (38). The blade (30) is maintained in contact against a sieve (40) fixed under the action of a return spring (44) associated with the blade-carrying shaft (27) so as to effect, upon turning, the pressing and the passage of the food products through the sieve, and the assembly formed by the blade (30) and the shaft (27) which carries the blade (30) being moreover adapted, in the case in which the blade (30) encounters a hard body, to rise against the force of the return spring (44). The blade-carrying shaft (27) of the drive shaft (19) uncouples when the assembly formed by the blade (30) and the blade-carrying shaft (27) rises.
