PCT No. PCT/CH92/00166 Sec. 371 Date Apr. 1, 1993 Sec. 102(e) Date Apr. 1, 1993 PCT Filed Aug. 20, 1992 PCT Pub. No. WO93/03620 PCT Pub. Date Apr. 3, 1993.The inventive method and apparatus suggests guiding the pasta directly into a drying climate after exiting from the die. Pasta strands of short goods are fed directly into the drying device from the extrusion die. The pasta strands can be cut either directly at the extrusion die or subsequently into packaging lengths after drying by means of an additional cutting device. It is possible to operate only the initial drying in this way, particularly to heat up the goods and then to carry out the final drying in a manner known per se, e.g. by portions. However, it is also possible to carry out the drying in its entirety, i.e. the pre-drying and final drying, according to the invention, particularly for short goods. The goods can be intensively dried at previously unaccustomed temperatures of 90 DEG C. to 120 DEG C., particularly during final drying from 15% to less than 13% product moisture. Further, it is preferably suggested to provide a cutting device for the pasta strands directly at the die, by means of which short as well as long goods substantially of packaging length can be cut. When the packaging length of the long goods must be cut accurately, a second cutting device can be provided after drying, which allows a particularly great flexibility of the installation for the production of different products ranging from longer goods to the shortest goods. |
