Abstract
For producing a hydrolized food product a stream of product is conveyed to a nozzle head (4) by means of a worm (1) and discharged via nozzles (8). Processed pieces of product are cut off from the stream of product one after another. The interrupter serving for this purpose displays a rotating element (5) that is arranged rigidly on the nozzle head side end of the worm (1) and rotates together with this latter. The rotating element (5) has recesses (10) that intermittently feed the stream of stock to the nozzle inlets (9) and sealing faces (12) that are arranged between the recesses (10) and seal the nozzle inlets (9) against the stream of stock between the feed phases. The edges (14) of the sealing faces (12), leading in the direction of rotation (13), guarantee the intermittent interruption of the stream of stock effecting cut-off of the pieces of product one after another.
