Description
Operate and monitor industrial freezers—such as batch, blast, spiral, or tunnel units—to freeze food, blood plasma, pharmaceuticals, or chemicals, meeting target temperatures, throughput, and product quality.
- • Adjust freezer, belt, and air-flow speeds to meet target product temperature, consistency, and throughput.
- • Monitor gauges, sensors, and product temperatures; adjust controls to maintain specified feed rate, freezer temperature, air pressure, and machine speed.
- • Record temperatures, production counts, materials processed, and test results on logs or electronic forms.
- • Read control panels for temperatures, suction and discharge pressures, and alarms; adjust valves and setpoints to maintain conditions.
- • Clear jams, remove ice buildup, and correct minor malfunctions; notify supervisors or maintenance as needed.
- • Start and stop pumps, feeders, and conveyors; open or close valves to admit product and refrigerant and to transfer product.
- • Assemble or change over freezer components; attach pipes, fittings, or valves using hand tools.
- • Scrape, dislodge, or break excess frost, ice, or frozen product from equipment to prevent accumulation.
- • Weigh packages and adjust filler or freezer settings to achieve specified fill weights.
- • Agitate, tumble, or space product to promote even freezing and prevent clumping or sticking.
- • Operate beaters, scrapers, agitators, or air systems to achieve required texture and prevent sticking in frozen products.
- • Load product onto belts, racks, trays, or hoppers and verify weights meet specifications.
- • Load and position cartons, trays, sticks, bags, or wrappers into dispensing equipment feeding the freezer.
- • Install forming fixtures and operate cutters to portion or shape frozen products to specification.
- • Place containers or product carriers into the freezer and remove them after the cycle is complete.
- • Inspect and flush lines with cleaning solutions or steam; spray and wipe equipment with approved sanitizers.
- • Sample and test product temperature, texture, or Brix as required, using probes, thermometers, or refractometers.
- • Initiate defrost cycles, drain condensate, and manage evaporator icing to maintain airflow and efficiency.
