Cone dryer, mixer

The vertical dryer, also known as a cone dryer, proves to be particularly advantageous in terms of its outstanding dischargeability. This aspect is gaining particular importance in industries where strict hygiene and batch cleanliness requirements apply.


The conical dryers can be designed in variants with or without a double jacket for heating. The mixing unit can be supplied heated or unheated, while drives and sealing systems are optimally adapted to the respective application requirements.

To exclude any possibility of contamination by lubricants in the product space, all drives and bearings are placed outside.

Of course, CIP and SIP systems can also be implemented.

Materials in contact with the product

Stainless steels are commonly used for the components of the conical dryer that come into contact with the product. The choice of material depends on the specific customer requirements and can range from simple carbon steels to high-grade stainless steels such as Hastelloy.

Requirement profiles

Depending on the intended use, the machines can be offered in a standard version for chemical applications or in foodstuff-compliant (FDA) or pharmaceutical (GMP) versions. The ATEX version is selected according to the underlying zone classification.


Our conical dryers are manufactured in a wide range of common sizes from 50 litres to 15 cubic metres.
