Steam infusion

Ever since the invention of thermal processing as a method for food preservation in the 19th century, there has been a relentless search to reduce the degree of thermal damage to the quality of food products.

Originally designed for boats, steam infusion was first used in pasteurization and has since been developed for further liquid heating applications.

There were literally hundreds of steam injection/infusion devises that were developed or investigated in the late 1950s and through the 1960s.

In the 1960s APV launched the first steam infusion system under the Palarisator brand name. Since then significant developments and progress have taken place which have led to one of the most sophisticated systems in the world.

This involves a 2-stage process for steam infusion whereby the liquid is cascaded into a large pressurized steam chamber and is sterilized when falling as film or droplets through the chamber.

Generally, steam injection and steam infusion heating systems are followed by flash cooling the product.
