FAGOR MRBIG-500 M 500 Litre Indirect Gas Boiling Kettle

This indirect gas boiling kettle warms liquids by heating water in a surrounding jacket, avoiding direct flame contact. The design promotes uniform heat transfer, making it suitable for preparing stocks, sauces, soups, and stews in bulk. The water jacket ensures gentle cooking, minimising the risk of burning while maintaining consistent temperatures throughout the process.

The user adds ingredients to the inner vessel, selects the required settings on the PLC touchscreen, and initiates the programme. Gas burners light automatically, warming the water jacket as the mixer circulates the contents. A pressure gauge and safety valve oversee the jacket pressure, releasing excess steam when necessary. The touchscreen allows real-time adjustments to temperature, mixing speed, and cooking duration, with alerts for each stage. Once cooking finishes, the contents drain through an adjustable bronze tap, which also provides hot and cold water for rinsing.

The inner vessel is made from AISI 316 stainless steel, while the outer jacket and lid consist of AISI 304 stainless steel. The lid includes a counterbalanced closing mechanism with heat-resistant handles, and the unit stands on a stainless steel frame with adjustable feet. A removable mixer, designed for easy cleaning, features stainless steel arms and Teflon-ceramic paddles that prevent food from sticking. The outer walls have a satin finish, and the worktop is also stainless steel.

Controls feature a PLC touchscreen for storing up to 100 customisable programmes, a pressure gauge for the water jacket, a manual pressure-release valve, and a safety valve set to 0.5 bar. The mixer speed ranges from 7 to 28 rpm, with an option to reverse direction. Gas burners, constructed from AISI 304 stainless steel, include a pilot light with piezoelectric ignition, a flue gas outlet grille, and a nozzle set for various gas types. The water jacket's level is managed by minimum and maximum level taps and an automatic refill system.

With a 500 litre capacity, this kettle handles large volumes without frequent refilling. The 42.75 kW power rating requires a dedicated gas supply. The dimensions of 1976 x 1835 x 1140 mm demand a fixed installation space, and the 875 kg weight needs a reinforced floor. A 400 V three-phase electrical connection powers the PLC and mixer motor, while the gas supply provides primary heating.

Cleaning involves removing the mixer and scrubbing the inner vessel and paddles with non-abrasive tools to protect the coating. The water jacket drains through the manual valve, and the outer surfaces clean with stainless steel cleaner. The lid and worktop lift for interior access, and adjustable feet allow levelling on uneven floors.

The MRBIG-500 M is an indirect gas model with PLC control and a removable mixer, designed for professional kitchens requiring large-scale boiling and braising equipment.
