Question 1

Why is a blast chiller required in a HACCP-compliant commercial kitchen?

Accepted Answer

HACCP food safety programmes require that cooked food not intended for immediate service must have its core temperature reduced below +8°C as rapidly as possible to prevent bacterial multiplication in the temperature danger zone (+8°C to +63°C). Dubai Municipality's food safety regulations, aligned with HACCP standards, require cook-chill operations to demonstrate rapid chilling compliance. A blast chiller reduces cooked food from +70°C to +3°C in under 90 minutes — far faster than refrigerator cooling — and provides the core temperature probe data and HACCP logging needed for compliance documentation.

Question 2

What is the difference between blast chilling and shock freezing?

Accepted Answer

Blast chilling reduces cooked food from +70°C to +3°C (chilled storage temperature) in under 90 minutes using high-velocity cold air. Shock freezing reduces food from ambient temperature to -18°C (frozen storage temperature) using an even more powerful refrigeration cycle, creating very small ice crystals within the food structure that cause minimal cell damage on thawing — preserving product quality better than conventional slow freezing. Kitco's blast chiller range includes models offering both blast chill and shock freeze modes in a single unit.

Question 3

What capacity blast chiller do I need for my hotel or restaurant kitchen?

Accepted Answer

Blast chiller capacity is measured in kilogrammes of product chilled per cycle, typically based on a standard product starting at +70°C. As a guide: a 10 kg capacity unit suits restaurants producing small-batch cook-chill daily; 20–40 kg units suit medium-volume hotel kitchens and institutional caterers; and 60+ kg units are specified for large hotel banqueting kitchens, hospital catering and airline meal production facilities. Kitco's team can size the correct blast chiller for your specific daily production volume.

Question 4

Do blast chillers require specific drainage installation in a commercial kitchen?

Accepted Answer

Yes. Blast chillers produce condensation and melt water during and after each chilling cycle that must be drained away from the unit. A floor drain adjacent to the blast chiller is required, and the unit must be positioned with sufficient clearance around the condensing section for adequate airflow. Kitco surveys your installation space before supply and confirms drainage, electrical supply and clearance requirements to ensure the unit can be correctly installed and operated in your kitchen.
