About this machine

This Guittard/RPA Process M-54 is a Z-blade mixer — sometimes referred to as a sigma blade mixer or kneader — a heavy-duty batch mixing machine designed to compound, knead, and blend viscous, dense, or paste-like materials. Z-blade mixers of this type are widely used across industries including food processing, confectionery, adhesives, rubber, plastics, pharmaceuticals, and chemical manufacturing, where thorough, high-shear mixing of thick or cohesive materials is required.

Built in 2003 and located in Barneveld, Netherlands, this used machine carries serial number 2661 and is constructed in mild steel. It has a total trough volume of 150 litres with a useful working capacity of 100 litres, and the trough itself measures 575 × 560 × 500 mm. The mixer operates at two selectable arm speeds of approximately 15 and 25 RPM, delivered through a double-geared drive arrangement that allows differential blade rotation — the standard configuration for effective Z-blade kneading action.

The machine is equipped with a jacket rated to 4 bar working pressure, enabling temperature control of the mix through heating or cooling media. The trough itself operates at 0 bar (unpressurised), while the design also accommodates vacuum operation, making it suitable for processes requiring degassing or atmospheric exclusion. The cover and adjustable packing glands are included as standard fitments, supporting both vacuum and pressure-assisted processing conditions.

Tilting of the trough is achieved hydraulically, and a hydraulic unit is included with the machine. This facilitates controlled, safe discharge of heavy or viscous batches without manual effort. The mixer has a floor footprint of 1.8 × 1.2 metres (excluding the drive unit) and stands 1.8 metres in total height, giving a clear indication of the space required for installation and operation.
