Key benefits

Flexible modular design

The kiln comes in modules with 2 to 8 heating sections and 1 to 3 cooling sections. This allows you to configure the machine depending on the throughput you need.

Low energy consumption

All key parts of the kiln are well insulated, helping reduce energy consumption.

Meets strict food safety standards

All parts of the kiln in contact with the product are made of stainless steel. There are no dead points inside the machine; this keeps the product flowing and prevents residues from building up.

Highlight features

Hydrothermal treatment of oats, sorghum and groats

Inactivates enzymes to create uniform, premium products

The kiln inactivates enzymes in the kernels, improving digestibility and creating a nutty taste. This prevents the finished product from becoming rancid. The kiln also treats the product evenly, by alternately charging the radiators in the heating compartments with vapor.


Designed for 24/7 operation

The kiln is sturdy, designed for safe and continuous operation even under demanding production conditions.


Designed for easy maintenance and cleaning

You can easily remove all air, vapor and condensed water lines. You can pull out the stainless steel radiators. There are also hinged cleaning flaps with quick closures in the cooling compartment's air outlet hoods.

You can precisely set the kiln’s retention time and dosing of moisture and heat. An electronic cycle control also regulates the process.
