Heat treating, preferably short-time heating a liquid product (2), comprises passing the product through a primary circuit (4) of a heat exchanger (3) and a liquid exchange medium through a secondary circuit (5) of the heat exchanger under maintaining a positive pressure gradient. The positive pressure gradient is generated by a voltage applied to the return circuit of the secondary vacuum. An independent claim is also included for a device (1) for heat treating a liquid product, comprising a heat exchanger, on which a primary circuit is designed for the product and a secondary circuit is designed for an exchange medium, pressure gauges for comparing an outlet side pressure of the primary circuit and a leading side pressure of the secondary circuit, and a suction unit associated with the secondary circuit. |
