Optimal preparation of your input materials

Individual solutions for ethanol production

Tietjen and ethanol production

Guaranteed fineness in artificial fermentation lines


The production of ethanol is a demanding process. Ethanol producers are therefore dependent on the safe and reliable operation of the crushing process at the beginning of the entire production process. The production of ethanol is traditionally carried out through the fermentation of sugar or starch. Fruits or crops are used for this purpose. Ethanol extracted from straw is also becoming an increasingly interesting option worldwide. Excellent grain structures with high throughput rates and availability are a precondition for highly competitive ethanol and alcohol production. We optimally prepare the input materials for your ethanol and alcohol production and deliver reliable capacity and quality commitments for our crushing. Take advantage of our experience in natural and artificial fermentation lines.

60 years of expertise
Grinding solutions for the production of ethanol and alcohol

We have been building hammer mills since 1959 and supply our customers with tailor-made systems: From simple self-feeding grinding systems for small operations to computer-controlled large chamber mills with automatic screen change. Our high-speed mills are well established in the production of bio-ethanol, drinking alcohol and in the brewing industry. These are robust universal machines for small to medium throughput volumes. They are suitable for coarse and fine grinding.

The VDK high-speed mill is one of the most successful machines for the production of ethanol and alcohol. It is a robust hammer mill for medium throughputs. The screen is made of two parts and can be changed without using any tools when the machine is at a standstill.  The VDK high-speed mill is capable of processing all cereals, oil fruits, starch plants and their by-products, individually or in the form of recipes.

Our feeders

A grinding plant can only operate efficiently if material is fed in at the optimal rate and is appropriately dosed.

The AGS air-gravity separator is well suited for the continuous separation of foreign bodies from bulk materials.
