Abstract
A method of coring a lettuce head, consisting in cutting the lettuce head (TS) transversely with respect to its axis (RR), above the core (TR), leaving a residue (E4) formed by the core and the remains of the leaves, while the residue (E4) is rotated about its axis while a jet of cutting water forming a cutting line (AA) is directed toward the base of the rotating residue (RR) to separate the leaf remains from the core (TR).
Claims6
1) Process for coring a lettuce head,
- characterized in that
- the lettuce head (TS) is fixed to a rotating support (2) of a shaft (RR)
- the lettuce head (TS) is cut transversely to its shaft (RR) above the core (TR), leaving a residue (E4) formed by the core (TR) with leaf remains,
- the power of a cutting water jet is adjusted according to the different hardnesses of the core (TR) and the main ribs (N1, N2, N3) of the leaves,
- the residue (E4) is made to rotate while a jet of cutting water forming a cutting axis (AA) is directed at the residue (E4) core base so that the cutting line (AA) shaves the surface of the core at the incipient point of the leaves and cuts the base (NB) of the main rib of the lettuce leaves to separate the leaf remains from the core (TR).

4) Device for coring lettuce heads
- including:
- a rotating support (2) for receiving the lettuce head (TS) fixed to the support (2) by its core (TR) oriented according to the axis of rotation (RR) of the support (2),
- a transversal cutting device (3a) for cutting the lettuce head (TS) transversely to its axis just above the core (TR) and forming a residue (E4) comprising the core (TR) and the bases of the leaves from the core,
- an adjustable-strength cutting water jet monitor (41), mounted to be adjustable so that its cutting axis (AA) intercepts the volume of the residue (E4) at the base of the leaves of the lettuce head,
- an over-pressurized water supply (47) to the monitor (41) and,
- a control unit (160) managing the operation of the transverse cutting device (Pn), the rotating support (2) and the cutting water jet nozzle (41).
