Is chiller the same as freezer?

is that chiller is something that chills, especially a machine that produces cold air, either for air conditioning, to prepare chilled foods etc while freezer is an appliance or room used to store food or other perishable items at temperatures below 0 celsius (32° fahrenheit).

What temperature does nitrogen freeze at?

Under normal atmospheric pressure, nitrogen can exist as a liquid between the temperatures of 63 K and 77.2 K. (-346°F and -320.44°F). Below 63 K, nitrogen freezes and becomes a solid. Above 77.2 K, nitrogen boils and becomes a gas.

What is a blast freezer?

A Blast Freezer is a specialized category of freezer used to preserve food at a very low temperature to prevent the growth of microorganisms. A Blast Freezer is also known as Shock Freezer.

What is the freezing point of liquid nitrogen?

The temperature of liquid nitrogen can readily be reduced to its freezing point 63 K (−210 °C; −346 °F) by placing it in a vacuum chamber pumped by a vacuum pump. Liquid nitrogen’s efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object, enveloping the object in insulating nitrogen gas.
