Screw Heat Exchangers

Cryogenic screw heat exchangers require precise design and finishing due to the extreme temperatures down to -196 °C. These systems are available in various configurations with options such as SIP integration, hygienic finishing, and nitrogen injection beneath the product bed.

Options for cryogenic Screw Heat ExchangersFlexible configurations and smart solutions for maximum cooling at extreme temperatures

Need technical advice or want to discuss the possibilities?

Cryogenic coolers come in various designs, from paddle shafts to screw ribbons or a combination of both. Below is a brief overview of the available options:

  • Direct product cooling is possible by injecting liquid nitrogen beneath the product bed using a LIXSHOOTER®. This saves nitrogen compared to dripping it on top of the product bed.
  • Space-saving insulation: when standard insulation is not feasible, high-tech insulation like Insulair Cryogenic F® can be used.
  • Hygienic design and finishing, such as polishing and ViwateQ®.
  • All components according to FDA guidelines, including seals and bearing grease.
  • Integrated SIP system.

Cryogenic Screws in the Food Industry – Cleaning Optimal Cleanability and Hygienic Design for Safe Handling in Cryogenic Applications

To properly clean the inside of a cryogenic screw and prevent bacterial growth, it is essential that the interior is as smooth and crevice-free as possible. By polishing the welds and treating the stainless steel surface with a ViwateQ® finish, the surface becomes so smooth that residue after cleaning is reduced to an absolute minimum.

Depending on the selected cleaning method (dry/wet), you can opt for an integrated SIP system or manual cleaning via top-side access hatches.

Preventing Frost Formation

In cryogenic coolers—where the lid often needs to be opened for cleaning—the lid seal is of great importance. Our lid seal consists of a quadruple silicone profile, which functions as a thermal barrier. As a result, no frost forms on the outside despite the large temperature difference. This eliminates the need for electric tracing at the lid seal, saving on liquid nitrogen consumption.

PIR blocks are often used as insulation; these are pre-formed and fully enclosed in a welded housing, preventing any contamination from entering. If there is insufficient space for standard insulation, a high-end alternative such as Insulair Cryogenic F® can be used. This material offers a lower thermal conductivity coefficient, allowing for a more compact design.
