Frozen yoghurt on a stick
Fill Silikomart moulds, harden in minutes and unmould clean, glossy shapes ready to dip and decorate.

Cakes, pies & sandwiches
Set each layer quickly for sharp edges, and sandwich frozen yoghurt between biscuits for a premium take-home dessert.

Take-away tubs
Harden freshly filled tubs so they hold their texture in the display cabinet and on the way home.

Why blast freeze frozen yoghurt?
Blast chilling
Brings cooked bases, sauces and fillings from +90 °C to +3 °C in 90 minutes – passing quickly through the temperature range where bacteria multiply.
Blast freezing
Takes product from +90 °C to -18 °C in 240 minutes with -40 °C air. Fast freezing forms small ice crystals, keeping frozen yoghurt smooth and desserts sharp-edged.
Blast freezer questions
Is a blast freezer different from a normal freezer?
Yes. A storage freezer holds product that is already frozen. A blast freezer removes heat very quickly, so products freeze with smaller ice crystals and better texture.
What tray sizes fit?
The Techfrost Entry line takes GN 1/1 gastronorm and EN 600×400 pastry trays, from 3 trays (JOF ONE 3) to 10 trays (E10).
Do I need three-phase power?
The JOF ONE 3 and E5 run on 230 V single phase with a standard 10 A plug. The E10 needs 400 V three phase.
How long does hardening take?
A few minutes for frozen yoghurt in Silikomart stick moulds; full blast-freezing cycles run to 240 minutes depending on the load.
