Flexible Design

The Hybrid is built with flexibility in mind, it can be adapted to freeze, chill, glaze harden and pre cool a wide range of food products including seafood, meat, poultry, bakery, dairy products, fruit and vegetables.

Starfrost Hybrid inline IQF tunnels are a highly versatile IQF systems that combine the design of a Turbo fluidised bed tunnel with the airflow characteristics of a Helix spiral freezer.

Energy Efficient

Advancements in our mechanical freezing technology and design deliver fast freezing and highest quality IQF, this provides food processors a new generation of mechanical freezing equipment.

Removing the requirement for nitrogen freezing, the compact Hybrid IQF Tunnel system delivers extremely rapid and effective freezing times at significantly lower costs than cryogenic freezing, with a typical 18-month payback when compared to a cryogenic freezer.

Bespoke Solutions

The single or multi belt design provides an ideal solution for upgrading from static blast freezing to progress to continuous in-line IQF processing, or for diversifying or expanding production.

Custom Built

In addition to rapid continuous automated cooling, the Hybrid can be custom designed for the glaze hardening of delicate products. The glaze hardening process increases yield, preserves texture and flavour of delicate products together with eliminating damage for maximised product quality and shelf life.
