Flash Pasteurization of Liquid Products

By flash pasteurization harmful microorganisms in beverages and liquid food are killed with the aim of improving microbiological stability and shelf life of the product.

The FlashPasto skid is designed to pasteurize the product gently without adversely affecting its color, its taste or its digestibility. For optimum results, pasteurization time, temperature and pressure have to be individually adjusted. Based on highly accurate process control, the unit guarantees constant pasteurization quality even at variable product flow.

To increase the energy efficiency of the system, the product is warmed up to the pasteurization temperature in two steps. In the first step it is heated in a heat recovery section where it flows in counter current to the hot, already pasteurized product. In the second step it is gently brought to the pasteurization temperature by the heating medium.

The FlashPasto skid can easily be expanded by a buffer tank as it is often required for installation directly in front of the filler.
