blast chiller is a specialized piece of equipment used in commercial kitchens and food service establishments to rapidly cool or freeze food items. It is designed to quickly bring down the temperature of hot or cooked food to safe storage temperatures, which helps preserve food quality, flavor, and nutritional value while preventing the growth of harmful bacteria. A blast freezer, also known as a shock freezer, is a specialized piece of equipment used in commercial kitchens, food production facilities, and industrial settings. It is designed to rapidly freeze food items to very low temperatures, much lower than what a regular freezer can achieve. Blast freezers are commonly used to preserve the quality, flavor, and texture of food, extend its shelf life, and maintain food safety standards.
