About this machine
This Kraus RTD-8 is a paddle dryer — sometimes referred to as a paddle processor or contact dryer — designed for the drying, heating, cooling, or reaction processing of bulk solids and pastes through direct heat transfer from heated surfaces rather than a heated gas stream. Kraus is a specialist manufacturer of thermal processing and mixing equipment, with paddle dryers of this type widely used in the chemical, pharmaceutical, and food processing industries where gentle, energy-efficient indirect heating is required.
This particular unit is the "Reactotherm" model, carrying serial number 8603 and dating from 1990. It is constructed throughout in stainless steel grade 1.4571 (the European designation for AISI 316Ti, a titanium-stabilised variant of 316 stainless offering enhanced resistance to intergranular corrosion), making it well suited to chemically aggressive process materials. The machine is mounted on a frame and is located in Barneveld, Netherlands.
The dryer has a total product volume of 8 litres, with a trough diameter of 170 mm and a trough length of 375 mm. The total heating surface area is 0.28 m². Heat can be applied both through the jacket, which adds a further 2 litres of volume, and through the heated shaft, contributing an additional 1 litre — allowing efficient heat transfer from multiple surfaces simultaneously. The jacket is rated for a working pressure of 16 bar, while the process side operates at a working pressure of 10 bar. The unit is also capable of operating under vacuum, extending its suitability to heat-sensitive or solvent-bearing materials. Maximum process temperature is 350 °C.
The paddle shaft is driven by a 7.5 kW, 500-volt motor that carries Ex (explosion-proof) certification, reflecting suitability for use in potentially hazardous atmospheres. Speed is fully adjustable via an integrated frequency inverter, allowing the paddle rotation to be matched to the process requirements of different materials.
The machine has a floor footprint of 1.8 × 0.9 metres and a total installed height of 1.8 metres. It is offered in used condition.
