Device and method for the high-pressure treatment of products

A method for high-pressure treatment of products, the method comprising:

• exposing the products to a high-pressure medium in a high-pressure chamber;
• and
• subsequently decreasing pressure in the high-pressure chamber in a first phase and in a second phase, wherein a mean pressure decrease rate in the first phase is higher than in the second phase, wherein the high-pressure chamber is in fluid communication with a discharge valve and a pressure transformer with a three-way valve being in fluid communication with the high-pressure chamber, the discharge valve and the pressure transformer such that the three-way valve has a first outlet leading to the discharge valve and a second outlet leading to the pressure transformer, the first outlet being opened with the second outlet being closed during the first phase, and the first outlet being closed and the second outlet being opened during the second phase.
