This unit carries serial number M.19065.B and was manufactured in 1982. It is constructed in stainless steel grade 1.4301 (AISI 304), making it suitable for hygienic and chemically demanding applications. The mixer has a total working volume of 2,000 litres, with a conical vessel measuring 1,924 mm at its largest diameter and standing 2,700 mm in cone height, giving a total machine height of 3,800 mm. The floor footprint is compact at 1.93 × 1.93 m.
The drive system is positioned at the top of the vessel and is powered by a 4 kW motor rated at 380/660 volt. A variable speed drive is fitted, with a maximum speed of 1,500 rpm, allowing the mixing intensity to be adjusted to suit different materials and process requirements. The bottom of the cone is supported by a pintle bearing arrangement.
For product loading, the vessel is equipped with a manhole of DN400 and an inlet with a diameter of 500 mm. Discharge is handled by two bottom outlets, each 200 mm in diameter, both fitted with sliding valves to control product flow.
