This Hermann Waldner mixer and blender — sometimes referred to as a mixing vessel or blending tank — is an upright, cylindrical unit built for controlled mixing and blending of liquid or semi-liquid products. Hermann Waldner is a German manufacturer with a long-standing reputation for precision-engineered process equipment used in the food, pharmaceutical, and chemical industries, where hygienic construction and reliable performance are essential.
The vessel is fabricated from grade 1.4435 stainless steel, a high-molybdenum austenitic alloy widely used in pharmaceutical and food-grade applications for its excellent corrosion resistance. It has a nominal content capacity of 100 litres, with a working volume of 22 litres noted in the documentation. The tank is fully insulated and fitted with a double jacket, the jacket itself constructed from grade 1.4404 stainless steel. The double jacket is pressure-rated to 2.5 bar and carries a working temperature of 90 °C, while the main vessel is rated for a working temperature of 80 °C — parameters that suit a range of heated processing applications.
Agitation is provided by a propeller agitator mounted from the top, a configuration that delivers efficient, consistent mixing throughout the vessel. Discharge is via a centrally positioned run-out at the middle of the bottom of the tank, allowing thorough and controlled product evacuation. The machine is offered in used condition, located in Germany, and is accompanied by its original type plate.
