MKN Steam Boiling Kettle 10019201 – Optima 850

One hundred litres of capacity, a 31 kW rated thermal load and a quoted 21 minute heat-up time set the profile of the MKN 10019201 steam boiling kettle. Within a 1200 x 850 x 700 mm Optima 850 module, that gives a high-output boiling station without pushing beyond a single work zone.

On board, the combination of volume and heat-up time translates directly into service planning and steam plant loading. A 21 min figure means the kettle can be brought from fill to boil within a single prep window, but it also means the steam system has to be sized for a 31 kW draw at a steam pressure between 0,5 and 0,8 bar. Where several jacketed kettles and other steam consumers share a line, that range and load belong in the discussion between galley designer and shipyard from the outset.

The working surface is a round stainless steel vessel with a Ø 630 x 397 mm internal geometry, fully welded with radiused base edges. That diameter and depth produce the stated 100 litres of capacity while keeping the vessel height compatible with the 700 mm body, so operators can see and stir the contents without climbing. The kettle vessel is pivot-mounted left and right within the frame, with a far-forward pivot point that gives controlled pouring rather than a sudden dump when the body is tilted. Net weight is 204 kg, with a gross shipping weight of 239 kg; those numbers are the ones the naval architect uses to check deck loading and handling during installation.

Steam boiling is specified here at a pressure band of 0,5–0,8 bar, which is the operating window the jacket and controls are designed around. Staying within that band keeps heat transfer where the 21 min heat-up time is valid; outside it, the kettle either labours or overheats. Product temperature control allows the operator to work to target temperatures instead of running the jacket at full capacity continuously, which is relevant when delicate items share the kettle with bulk boiling duties.

A large drain valve with strainer at the lowest point of the vessel allows partial or full draw-off without tilting when the product suits that method, and keeps particulates out of the drain line. Where batches are heavy or the deck space in front of the kettle is tight, that option can be more practical than relying solely on the pivot. The double-walled hinged lid on a swivel joint, with a condensate drip strip, keeps steam and heat over the vessel and returns condensate to the product rather than letting it run down the front.

Build and control

• Stainless steel 1.4301 (AISI 304) throughout
• Self-supporting closed construction
• Round stainless steel vessel with radiused base edges, fully welded
• Ergonomic knob control
• Kettle vessel pivot-mounted left and right within the frame
• Far-forward pivot point for controlled pouring
• Large drain valve with strainer
• Double-walled hinged lid with swivel joint and condensate drip strip
• Product temperature control
• R3/4" tap with 250 mm reach for filling

This kettle suits a galley that needs 100 litre boiling capacity in a single Optima 850 position and has a steam system comfortable with a 31 kW, 0,5–0,8 bar load. It is too much body for very small complements that seldom run more than half that volume, where a smaller kettle in the same line would be easier to justify in steam and deck-space terms.
