FAGOR Autoclave 300 L Electric Boiling Kettle MRIE-300 A

A boiling kettle transfers heat to large volumes of liquid through a surrounding water jacket, avoiding direct contact between the heating element and the food. The element warms the water in the jacket, which in turn warms the inner vessel evenly and gently. This indirect method prevents hot spots, scorching and local overheating, giving consistent results across the entire 300 litre capacity. The sealed autoclave version adds a locking lid and a safety valve, allowing the vessel to hold a slight positive pressure that raises the boiling point and speeds cooking without evaporation losses.

To operate the kettle, the operator fills the inner vessel with the liquid or product, closes the lid and locks it with the chrome-plated clamps. The water jacket is filled to the marked level through the automatic refill system or the manual taps. The power is switched on and the heating intensity is set with the control dial. As the water in the jacket warms, it transfers heat to the inner vessel; the safety thermostat monitors the temperature and cuts power if the water level falls too low or the temperature rises too high. Once the cooking cycle is complete, the operator releases the pressure through the safety valve, unlocks the lid and drains the product through the insulated discharge tap at the front.

The 300 litre capacity allows batch cooking of soups, stocks, sauces or stews in a single load. The 36 kW power rating requires a dedicated 400 V three-phase circuit, typical of professional kitchens with heavy equipment. The 300 kg weight means the unit is floor-standing and must be positioned on a stable, level surface; the adjustable legs allow fine levelling. The footprint of 1200 by 1270 mm takes a fixed space on the worktop or floor, and the 900 mm height allows access from a standing position without bending.

The inner vessel is made of AISI 316 stainless steel, chosen for its corrosion resistance in contact with food acids and salts. The walls and lid are AISI 304 stainless steel, satin-finished for durability and ease of cleaning. The outer jacket and supporting frame are also stainless steel, with satin-finished surfaces that resist fingerprints and scratches. The discharge tap has an insulated, heat-resistant handle for safe operation, and the lid is fitted with a silicone gasket and locking clamps for the autoclave version.

Controls include a power switch, a heating intensity dial, and manual taps for the water jacket level. The safety valve and thermostat are automatic and require no user setting. The water jacket has minimum and maximum level taps for manual filling, and an automatic refill option when connected to a water supply.

Cleaning involves draining the inner vessel through the discharge tap, rinsing with water and detergent, and scrubbing with a non-abrasive pad. The water jacket is drained through its own taps and flushed periodically to remove scale. The satin-finished surfaces wipe clean with a damp cloth, and the silicone gasket is removed and washed separately.

The MRIE-300 A is the autoclave version of the 300 litre electric boiling kettle, equipped with a locking lid and safety valve for sealed cooking. The catalogue places it in the professional cooking equipment section, under electric boiling kettles for large-scale food production.
