Groen Floor-Mounted Steam Jacketed Kettle with Dual Agitators

This is a heavy-duty industrial steam-jacketed kettle manufactured by Groen. The unit is constructed from high-grade 304 or 316 stainless steel, featuring a deep hemispherical cylindrical body designed for large-batch food processing. It is equipped with a dual agitation system mounted on a bridge over the top lid, consisting of a vertical drive motor and a secondary green-cased motor, likely for scraping and high-speed mixing respectively. A front-mounted control housing includes a circular pressure gauge and an integrated site glass. It features a large diameter product discharge valve at the bottom right and is connected to external plumbing via a red-handled valve. The lid is a heavy-duty reinforced hinged design, currently shown with protective insulating pads resting on top. The unit exhibits standard industrial wear including surface scratches, minor water spotting/mineral buildup, and some light oxidation on external hardware, but appears structurally sound and well-maintained. Manufacturing stamps on the side panel indicate technical specifications like ASME certification and model numbers. It originates from the late 20th to early 21st century and represents high-end commercial kitchen craftsmanship.

Upon visual inspection of the Groen floor-mounted steam-jacketed kettle, I find it to be a robust, high-specification piece of industrial food processing equipment. The unit features a dual-agitation bridge system—a high-value configuration essential for viscous products requiring constant surface scraping and uniform heat distribution. The presence of the ASME certification stamp and Groen nameplate suggests authentic commercial craftsmanship, known for its longevity and adherence to safety standards. The stainless steel body shows expected surface marring and minor mineral scaling consistent with a 'used-good' condition in a working kitchen environment. The market for used Groen agitation kettles remains strong due to the high cost of new replacements, which often exceed $45,000 for this specific configuration. Comparables for 60-to-100-gallon units with dual agitation and bottom discharge valves range significantly based on agitation complexity. The integrated control housing and pressure gauge add to its marketability. Negative factors impacting value include the visible oxidation on external hardware and the lack of a verified maintenance log for the motors and steam jacket integrity. Limitations of this virtual appraisal include the inability to perform a hydrostatic test on the jacket, a phase-load test on the agitation motors, or a verification of the scraper blade condition. For final authentication and valuation, a physical inspection is required to check for 'pitting' corrosion inside the kettle, certify the pressure relief valve, and verify the electrical specifications against current local codes. Documentary evidence of the last professional boiler inspection would significantly bolster the resale premium.
