To keep up with the growing consumer demand for plant-based milk products, HRS Heat Exchangers has added a new Direct Steam Injection System to its range of pasteurisation and sterilisation systems.

According to HRS, the benefit of sterilising using direct steam injection is the speed of the process, with sterilisation temperatures of 100-145˚C being reached in approximately one second. For products such as plant milks, this rapid heating “prevents cooking of the product and formation of caramel-type compounds which can darken the product or produce unwanted flavours”.

For products where direct steam injection is desirable, HRS Heat Exchangers has introduced the HRS DSI Series, which injects food grade steam into liquid products, providing an instant increase in the thermal process.

“At HRS, we are always looking to provide full system solutions for the thermal treatment processes required by our clients,” says Matt Hale, international sales and marketing director at HRS Heat Exchangers.

“As part of this we have introduced the DSI Series of steam injection modules for the pasteurisation and sterilisation of products such as increasingly popular plant milks.

“The first DSI Series unit has been running successfully for a number of months now and we are pleased to be able to offer another solution to our customers.”
