ICE CREAM CONTINUOUS FREEZER
A continuous ice cream freezer is an industrial machine designed for the large-scale production of ice cream, providing a constant, uninterrupted stream of finished product with precise and uniform quality.
It simultaneously performs the three essential steps of ice cream production: freezing, mixing, and aeration (whipping in air).
How a Continuous Freezer Works 🍦
The process within a continuous freezer is highly automated and involves several integrated components:
* Mix Pumping & Air Injection: A controlled flow of pasteurized liquid ice cream mix is drawn from a holding tank by a mix pump (often a gear or piston pump). At the same time, a measured amount of filtered, compressed air is injected into the mix flow.
* Freezing Cylinder: The pressurized mixture of liquid base and air is pumped into a highly-efficient, jacketed freezing cylinder (or barrel). This cylinder is surrounded by a boiling refrigerant (like ammonia or Freon), which rapidly removes heat from the mix.
* Scraping and Whipping (Dasher): Inside the cylinder, a rotating component called a dasher is equipped with sharp scraper blades.
* The blades continuously scrape the partially frozen layer of ice cream off…Read update
