Equipment for cooling a continuously extruded product.

摘要

The present invention relates to a method for cooling continuously an extruded product, characterised in that the product (10) passes successively through at least three cooling zones in the direction of travel in the tunnel: an upstream zone (1) for cooling by convection, in which the gas and the product travel in opposite flow directions, a zone for cooling (2) by atomisation of cryogenic fluid onto the product, and a downstream zone (3) for stabilisation, in which the gas and the product travel in the same flow direction. …It also relates to an installation for carrying out the method. ……
