HST HLI high-pressure homogenisers

The HLI series high-pressure homogenisers from HST are suitable for the production of UHT dairy products and desserts as well as milk-based drinks, vegan beverages, and fruit juices. The series has been added to complement the HL range, with the 'I' in HLI standing for ‘integrated’ and underscoring the design changes implemented.

The 55 to 90 kW systems can process up to 13,000 L/h at 200 bar. Three models are available: HLI55, HLI75, and HLI90, all in the same configurations as the HL series and including an option that fulfils the European Union’s ATEX (Equipment for potentially explosive atmospheres) Directives. Additional models for the lower output range to 45 kW are currently in development. The systems in the new series each consist of a three-piston high-pressure pump with a homogeniser valve at the outlet.

A compactly dimensioned drive design eliminates the need for additional units or coolants, which makes for a reduction in operating costs for media and electrical power during production.

The homogeniser valve on the HLI series can be matched to the required physical stability of UHT dairy products, vegan beverages, desserts and fruit drinks.

Optimised flow conditions make it possible to obtain the same product quality at a lower homogenising pressure. Of course, all areas that come into contact with the product are made in accordance with the latest hygiene requirements.

The HLI series can be configured for either aseptic or non-aseptic processing. The aseptic models of HST homogenisers use technology that entails a series of sterile barriers and can be equipped with high-grade temperature and flow metering capabilities on request.
