This Hermann Waldner is a used mixer and blender — sometimes referred to as a stirring vessel or mixing tank — designed for blending, agitating, and processing liquid or semi-liquid products in industrial and food-grade applications. Hermann Waldner is a well-established German manufacturer known for producing hygienic processing and filling equipment, particularly for the food, beverage, and pharmaceutical industries.
The vessel is constructed entirely from stainless steel grade 1.4401 (AISI 316), offering good corrosion resistance and suitability for demanding process environments. It has a total capacity of 200 litres and is configured as a closed stirring vessel with a dished bottom and a dished top side, dimensions of 800 mm diameter by 900 mm tall, and a floor footprint of 0.80 × 0.80 m. Overall height, including legs, reaches 2.20 m. The vessel is mounted on legs fitted with wheels, making it manoeuvrable within a facility.
The unit is equipped with a jacket of 25 litres volume, rated to a working pressure of 2 Bar, allowing for temperature-controlled processing through heating or cooling media. The vessel itself operates at 0 Bar working pressure, and the maximum process temperature is 90°C. A propeller stirrer is fitted, driven by a 1.1 kW motor running on 230/400 volt supply at 915 rpm; the motor carries an Ex rating, indicating suitability for use in potentially explosive atmospheres.
Access and process connections are well specified. The vessel features a manhole with a DN600 cover, top connections, and a DN40 outlet fitted with a ball valve. Additional equipment includes a ball cleaning system for internal CIP-style cleaning, a John Crane mechanical seal, and a thermosyphon vessel associated with the seal arrangement — all of which are relevant for maintaining hygienic operation and seal integrity. The machine dates from 1984 and is located in Barneveld, the Netherlands.
