IQF Tunnels - Starfrost

IQF Fluidised Tunnels

TURBO - innovative technology for fluidised food product


Individually quick freezing
Starfrost’s Turbo is a fluidised bed tunnel freezer. This twin belt fluidisation system allows effective individual quick freezing of large quantities of loose products specifically fruits and vegetables.

Even wet, sticky and delicate food items normally considered difficult to freeze are carefully handled and effectively processed.



This freezer is designed as a two stage freezing system with each stage being carried out on a separate conveyor belt. High performance fluidisation maintains separation of the product and delivers consistent crust freezing, maximising yield and delivering premium quality frozen foods.


Sequential defrost allows constant operation for up to 2 weeks, maximising product capacity and profitability. 


Suitable product applications include French fries, frozen herbs, bean sprouts, cooked rice and pasta, minced meat and a wide range of fruit and vegetables such as mushrooms, onions, peas, tomato and diced peaches.
