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.

Abstract: Individual suspension of satellite cooling tubes with the aid of wire cables in the region of the discharge end of a revolving tubular kiln in two support locations spaced apart on the axial direction. Each suspension unit comprises a number of suspension elements selectable according to the operative requirements. These elements preferably include three pretensioned wire cables anchored to suitable retaining elements secured to the kiln casing. In a preferred embodiment, the wire cables are arranged so that two of them exert upon the associated cooling tube a tractive force, the resultant of which is oriented towards the kiln axis, whereas the third wire cable, which is anchored by at least one resilient element, applies to the cooling tube a force directed in opposition to the resultant and of equal value.
