Abstract

The invention relates to a method for granulating plastic having a high softening temperature, in particular of above 120° C., using a perforated plate for producing strands of molten plastic and a subsequent process chamber containing a process fluid and including a chopping device, from which a mixture of process fluid and granulate is then discharged into a cooling section for cooling said granulate. The process chamber is filled with a process fluid, in particular water, at a temperature of more than 120° C. and at a pressure of over 2 bar, and the mixture of process fluid and granulate, whose pressure will be maintained as it passes through the cooling section, will then be supplied to a separator in which the granulate, which has first been directed through a pressure lock for bringing it down to ambient pressure, will then be separated from the process fluid and discharged.
