The Metos Combi-Kettle is a versatile professional kitchen appliance designed for food preparation, offering a range of functions including heating, mixing, and cooling. This manual covers the Proveno Combi Pro, Combi Pro + EasyRun, Cool, and Cool Pro versions, available in various capacities (40, 60, 80, 100, 150, 200, 300, and 400 liters).
Function Description
The Combi-Kettle is a pressurized vessel constructed from stainless steel (AISI 304 for the inner bottom and jacket, AISI 316 for the kettle). It features a triple-jacketed and thermally insulated design. The kettle is heated by steam provided from the facility's steam network.
Mixing Function: The kettle is equipped with a tilting motor (40-80-litre kettles) or gear motor (100-400-litre kettles) for mixing. An auto-reverse control dial allows for adjusting mixing speed and direction. The mixing tool is designed for easy installation and removal. Different scraper sizes are available depending on the kettle capacity, ensuring efficient mixing for various food types, from large quantities of mashed potatoes to delicate dough.
Heating Function: The appliance offers precise temperature control for cooking. The display shows the desired temperature, and the heating process can be started and stopped via the control panel.
Cooling Function: The Combi-Kettle can be equipped with an icebank cooling system (C3 option) or manual cooling. Cooling is achieved by circulating cold tap water in the kettle's steam jacket. The cooling process can be initiated and controlled via the display, with options to set target temperatures.
Water Filling: The kettle supports both automatic and manual water filling. The automatic water fill function allows for setting a desired amount of water in liters.
Tilting Function: The kettle bowl can be tilted for emptying its contents. The tilting mechanism is operated by a button on the control panel, and the kettle returns to an upright position after emptying. Safety features prevent tilting when the lid is open or when the mixer is running.
Programming: The EasyRun programming feature allows users to store and activate pre-set programs for various cooking processes (P1-P6), simplifying repetitive tasks. These programs can include gentle stirring, powerful auto-reverse mixing, mashing, whipping, and cooking for specific durations.
HACCP System: The Combi-Kettle can be equipped with a self-control HACCP program (C1 option) to monitor and record critical control points during food preparation, ensuring food safety.
