Blast chillers rapidly cool food by circulating cold air through the unit until temperatures fall to safe levels. They are designed to lower the temperature of cooked foods quickly enough to minimize bacterial growth, ensuring the food is out of the 40 to 140 degree Fahrenheit danger zone within 90 minutes, rather than the hours it can take when foods are stored in a refrigerator.Know More
Bacteria thrives between the temperatures of 40 and 140 degrees Fahrenheit. The longer food stays within this range, the greater the risk of bacterial growth that makes the food dangerous to eat. A conventional refrigeration unit may take too long to cool a large volume of hot food, and the heat from the food may also raise the ambient temperature of the refrigerator high enough to encourage bacterial growth in other items stored inside the unit.
Blast chillers are also suitable for freezing food and offer some advantages over a traditional freezer unit. Rapid freezing produces fewer and smaller ice crystals in food, which results in less damage to the food item due to perforated cell walls. This improves the texture of quick-frozen food once it is reheated. More expensive than refrigerators, blast chillers are typically used in food service and restaurants rather than home kitchens.Learn more about Small Kitchen Appliances
A cotton candy machine works by rapidly spinning and flinging threads of hot sugar syrup through small holes in a cone that sits in the center of the machine. The cooled sugar threads accumulate in an outer bowl, and the candy maker gathers them onto a cone.Full Answer >
Electric kettles work through a shielded heating element, activated when the kettle is plugged into an outlet. They shut themselves off automatically when the water reaches a specific temperature, boiling water faster than stove-top tea kettles. Some kettles whistle to indicate heat, while others do not; this is contingent upon the design of the product.Full Answer >
A chiller works by compressing refrigerant gas and condensing it into a liquid, which then triggers the metering device to decrease pressure. Once the pressure drops, the liquid evaporates and pulls heat out of the water.Full Answer >
An air-cooled chiller is a refrigerating system used to cool or dehumidify air by flowing a refrigerant over an evaporator tube bundle. This process draws vapors out of the evaporator and ultimately allows the pressurized refrigerant to condense on a system of tubes and cool the air. When the refrigerant passes through an expansion device, it lowers its temperature. Air-cooled chillers are used in a number of professional settings.Full Answer >
