Blast Freezer Tunnel: Freezing Curve & Refrigeration Energy

Food processing is one of the most energy-intensive links in the cold chain, and blast freezing is where most of that electricity is spent. This simulator sends real product — a chicken breast, a cod fillet, or loose IQF peas — through a 3D freezing tunnel, tracking each item's core temperature through the true three-stage freezing curve: sensible precooling, a flat latent-heat plateau at the product's freezing point, and slower subcooling once it's fully solid. Air temperature and air velocity control how fast heat leaves each item; conveyor speed sets how long it stays inside. Push the belt too fast for the chosen conditions and items exit still unfrozen — visible both in the 3D tunnel and in the readouts. A live refrigeration model converts the heat pulled from the product into an electrical power draw and a coefficient of performance that falls as the air gets colder, ending in the number a real plant is billed on: specific energy in kWh per tonne of product frozen.
