An ice cream hardener is a piece of equipment used in the commercial production of ice cream. It is typically used in the final stages of the ice cream production process to freeze the ice cream mixture to a hard consistency before it is packaged and sold.

Ice cream hardeners work by rapidly freezing the ice cream mixture using a combination of low temperatures and mechanical agitation. The mixture is typically pumped into the hardener, where it is subjected to a temperature of around -40°C (-40°F) and agitated using blades or paddles. This process helps to break up ice crystals that may have formed during the freezing process, resulting in a smoother and creamier texture.

Ice cream hardeners are typically used in large-scale ice cream production facilities, such as ice cream factories and commercial kitchens. They are an essential component of the ice cream production process, helping to ensure that ice cream is frozen to the correct consistency and quality standards.

Overall, ice cream hardeners are an important tool for commercial ice cream production, helping to ensure that ice cream is produced efficiently and to a consistent quality. They help to create ice cream with a smooth and creamy texture that is free from ice crystals and other defects, resulting in a better product for consumers.
