Commercial Ice Machine Product

Overview

A commercial cuber makes clear, hard ice on a chilled metal plate, then drops finished cubes into an insulated bin below. It runs in two repeating phases — a long freeze and a short harvest — and keeps cycling until the bin fills. The clarity comes from the freezing method: water is pumped continuously over the cold plate so only pure water freezes onto it while minerals stay in the flowing film and wash away.

The machine pairs a sealed Refrigeration System loop with a recirculating Water System. During the freeze, the Recirculation Pump floods the face of the Evaporator Plate while refrigerant boiling behind it pulls the plate below 0 °C, so a slab of cubes grows cell by cell in the grid. A float switch tops up the sump from the mains through a solenoid valve. When the slab is thick enough, the Harvest Mechanism mechanism takes over.

Everything sits in a stainless Cabinet & Housing over the Storage Bin, whose thermostat stops production the moment the ice pile reaches the sensor.

How it works

Cooling is an ordinary vapor-compression cycle. The Hermetic Compressor raises refrigerant pressure and temperature; the gas condenses in the air-cooled Condenser Coil with help from the Condenser Fan, then a thermostatic expansion valve meters liquid into the evaporator where it boils and freezes the cubes. Throughout the freeze the recirculation pump keeps water sheeting across the plate.

To release a batch, the controller opens the Hot-Gas Solenoid Valve, routing hot discharge gas straight to the evaporator. The plate warms just enough to melt the cubes loose, and the slab slides down onto the heated Harvest Cutting Grid, which cuts it into individual cubes that fall into the bin. A hinged ice curtain swings open as the cubes drop and its switch tells the controller the harvest finished, starting the next freeze.

The Control Board board sequences all of this — compressor, pump, fill valve, and hot-gas valve — through relays, watches plate and bin thermistors, and shows status and fault codes on its LCD. When the bin thermostat reports full, the machine parks until ice is drawn down.
