Soft Serve Ice Cream Machine

Overview

The soft serve machine freezes liquid dairy mix into dispensed soft ice cream on demand. Two refrigerated hoppers hold mix at 2–4 °C; gravity feeds it into freezing cylinders where a rotating beater scrapes the chilled barrel wall, whipping air into the mix as it freezes to a serving temperature of -6 to -4 °C. The twin-cylinder layout gives two flavors plus a center twist, producing about 18 litres per hour.

How it works

The machine is housed in the Cabinet & Housing, a stainless body with a drip tray and removable service panels. Liquid mix is poured into the Mix Hopper, a refrigerated tank that keeps the reserve cold and food-safe until it is drawn down. Mix passes by gravity into the Freezing Cylinder, the heart of the machine: a refrigerant-jacketed barrel containing a motor-driven beater whose scraper blades shave freezing mix off the wall and fold air into it, building the 30–40% overrun that gives soft serve its texture.

Cooling is supplied by the Refrigeration System circuit, a sealed R404A system with compressor, condenser, and expansion valve feeding the cylinder jacket. The Dispensing Assembly assembly is a spring-loaded draw valve on the faceplate; pulling the handle opens the port and extrudes product through a star nozzle.

The Control System runs the freezing logic, holding product consistency by monitoring beater motor load, stiffer product draws more current, and cycling the compressor to maintain it. It also runs the hopper refrigeration and a heat-treat or standby cycle that keeps idle mix safe between rushes.
