Blast chiller GEMM 45100018

A shock freezer rapidly removes heat from food by circulating air at sub-zero temperatures, lowering the core temperature in minutes rather than hours. This method locks in moisture, texture and nutrients, preventing ice crystals from damaging cell structure. The GEMM BCB/05R applies this principle to professional kitchens, where speed and consistency determine shelf life and food safety.

The operator loads up to five GN 1/1 trays onto the included stainless-steel structure, which is spaced at 67 mm intervals to allow air to flow evenly around each tray. Once the door is closed, the electronic control panel is set for either freezing or chilling mode. The unit can be programmed by time or by temperature sensor, so the process stops automatically when the target is reached. The refrigerant R290 circulates through the evaporator, absorbing heat from the food and releasing it outside the cabinet, while the 60 mm insulation minimises heat gain from the kitchen.

The BCB/05R is built from stainless steel inside and out, chosen for its resistance to corrosion and ease of sanitising in high-volume environments. The exterior dimensions of 520 mm wide, 850 mm deep and 880 mm high allow it to fit through standard kitchen doorways and under most worktops, while the 80 kg weight requires two people or a trolley to move it into position. A single-phase 230 V, 50 Hz supply powers the compressor and fans, drawing 0.791 kW under load, which matches the circuit capacity of a typical commercial kitchen.

Cleaning follows from the construction: the trays and structure lift out for washing in a sink or dishwasher, and the interior surfaces are wiped down with a cloth and food-safe sanitiser. The refrigerant R290 is non-toxic and has low global-warming potential, reducing environmental impact without compromising performance. The unit is rated for climatic class 5, meaning it maintains its specified capacity even when the kitchen temperature and humidity are high.

The BCB/05R is supplied with a tray structure and 67 mm pitch as standard. It accepts GN 1/1 trays, making it compatible with standardised catering containers used across professional kitchens. This model is positioned in the GEMM catalogue under blast chillers and shock freezers for professional food production.
