The compact Diamond GTP-3/1R blast chiller and blast freezer is designed for professional foodservice operations that require maximum food safety, consistent product quality and precise process control. Thanks to its compact dimensions, it is ideal for kitchens with limited space and allows installation under a worktop or beneath a worktable shelf.
FAST BLAST FREEZER GTP-3/1R
- The unit is engineered for rapid chilling and shock freezing, effectively limiting bacterial growth while preserving the structure, flavour and nutritional values of food, fully supporting the principles of a modern cold chain.
- Ideal for restaurants, hotels, catering operations, pastry shops, bakeries and professional kitchens requiring consistent product quality and maximum food safety.
Capacity and performance
- Capacity: 3 × GN 1/1.
- Production per cycle:
- 8 kg (+70 °C → +3 °C) – blast chilling.
- 5 kg (+70 °C → −18 °C) – blast freezing.
- Stainless steel tray runners for pans and GN containers, 70 mm spacing.
Control and operation
- Digital control panel with clear and intuitive interface.
- Control of chilling and freezing cycles with “Hard / Soft” function.
- Settings by time or by core temperature using a core temperature probe (standard equipment).
- Programmable electronic controller, housed in a closed, waterproof box.
- End-of-cycle holding function with audible alarm.
principle of blast chilling and freezing
- In food hygiene and safety, the fundamental principle of blast chilling and freezing is the rapid reduction of core temperature:
- chilling from +70 °C to +3 °C within 90 minutes (UK standard), or from +65 °C to +10 °C within 110 minutes (NF standard),
- freezing from +70 °C to −18 °C within 240 minutes (UK standard), or from +65 °C to −18 °C within 270 minutes (NF standard).
- Diamond blast chillers and blast freezers are designed to reliably ensure this principle, contributing to maximum food safety, quality and shelf life.
