Abstract
A method and a device for hot-filling a liquid product with a flash pasteurizer comprising a first and a second heat exchanger, a filling station, a cooling tunnel for cooling filled containers, and a heat pump. Prior to the filling process, the product is heated to a target temperature in the flash pasteurizer. Coolant is conducted from the cooling tunnel to the second heat exchanger, so that at least a part of the thermal energy of the coolant can be transferred to the product. The product is then conducted from the first to the second heat exchanger, wherein a further part of the thermal energy can be transferred to the second heat exchanger by the heat pump using a heat transfer medium to heat the product to the target temperature. The heat transfer medium is additionally heated by a heater arranged between the heat pump and the second heat exchanger.
