Distribute
The feed elevator delivers product to the tunnel. An even bed lets air reach the pieces across the width of the belt.

Lift and separate
Cold air rises through the mesh. Pulsation helps wet pieces separate while their surfaces begin to freeze.

Watch the bed
Look for pieces moving independently. Share the incoming temperature, piece size and target tonnes per hour when sizing a tunnel.
01 / How Efes works
How Efes works
Efes combines two pressure-controlled freezing zones with mechanical pulsation. Air speed, direction and pressure are tuned to the product so pieces remain in motion rather than freezing into clumps.
Metered feed
The product is distributed evenly across the stainless-steel wire belt to create a controllable bed depth.
Twin pressure zones
P1 and P2 chambers manage air velocity and angle through the product bed for staged heat removal.
Pulsation & separation
A momentary pressure change lifts and agitates the product vertically, helping wet or sticky pieces separate.
Rapid final freeze
The product moves quickly through the critical freezing zone before the second stage brings it to target core temperature.
Fast passage through approximately −1°C to −5°C helps limit ice-crystal growth and supports product texture.

Product entry
Redler-type beltless elevator and controlled feed distribution.
Crust-freezing zone
Fast surface set reduces sticking and supports early separation.
Finishing zone
Second-stage residence time brings the product to its target core temperature.
Hygiene & controls
Belt washing, automatic lubrication, defrost and PLC-based operation.
