Blast chiller Stalgast 849033

A blast chiller rapidly lowers the temperature of hot food to safe storage levels, preventing bacterial growth and preserving texture. Instead of relying on still air in a standard refrigerator, this unit forces cold air across the trays with a powerful fan. The air absorbs heat from the food and carries it to the evaporator coils, where the refrigerant absorbs the heat and expels it outside the cabinet. This continuous cycle cools food far faster than a domestic refrigerator can, meeting food safety regulations for professional kitchens.

The operator loads up to three GN1/1 gastronorm trays or 400x600 mm trays into the cooling compartment. The electronic controller is set to the target temperature: +3 °C for chilled storage or -18 °C for frozen storage. The unit starts automatically, circulating cold air evenly across every tray. The display shows the current temperature and the remaining time, which adjusts as the food cools. Once the cycle finishes, the unit switches to holding mode, keeping the food at the set temperature until it is removed.

The cabinet is constructed from stainless steel with rounded internal corners to eliminate crevices where food debris could collect. Forced air circulation ensures even cooling across all trays, while adjustable feet allow the unit to sit level on uneven floors. The refrigerant blend of R290 and R600a is chosen for its efficiency and lower environmental impact compared to older refrigerants.

The 1.15 kW power rating indicates the electrical load the unit draws during operation, requiring a dedicated 230 V circuit. The 750x750x770 mm footprint fits into a standard worktop space, allowing it to be positioned near the hot line for immediate transfer of cooked food. The temperature ranges of +70 °C to +3 °C in 90 minutes and +70 °C to -18 °C in 240 minutes define the unit's capability for chilling or freezing, covering the needs of most professional kitchens.

Cleaning involves wiping the interior with a damp cloth and mild detergent, focusing on the rounded corners to remove any residue. The forced air system should be checked periodically to ensure the fan and vents remain unobstructed. The electronic controller requires no maintenance beyond keeping the display and buttons free of grease.

This model is designed for use with GN1/1 and 400x600 mm trays, standardising it with existing kitchen equipment. The catalogue places it in the refrigeration section, under blast chillers and shock freezers.
