Description
The Dosemat DD is a state-of-the-art tanning drum specially developed for the uniform and efficient processing of hides and leather.
This machine is equipped with an intelligent liquor circulation system that ensures homogeneous distribution and application of leather chemicals. The Dosemat DD features a robust design with double suspension and offers outstanding performance and reliability.
It is ideal for industrial applications with high capacity requirements. The drum of the Dosemat DD has perforated inner shells that divide it into several working areas.
This enables optimum liquor circulation and uniform treatment of the leather.
The liquor circulates during drum rotation via scoop pockets and a mixing box, which improves the dosing and distribution of chemicals.
The design of the paddles ensures homogeneous treatment and application of the auxiliaries.

- Save resources: The Dosemat manages with considerably less liquor than all comparable tannery barrels.
- Perforated inner shells: The drum is divided into three working areas.
This three-chamber system enables a particularly effective fulling effect and allows 60% more loading compared to a single-chamber drum. - Extra large doors: Openings of up to 3.5 m² allow the drum to be loaded and emptied quickly.
- Fastest liquor circulation: The jet cross-flow system offers the most efficient liquor circulation in the world.
Water and chemicals are mixed in just a few seconds and distributed across the entire width of the drum. - Extremely fast deflocculation: The liquor is discharged directly into the sewer system via the mixing vessel cleanly and in the shortest possible time.
- Control option: Temperature, pH value and water quantity and thus chemical intensity can be easily checked at any time.
Add all the components you need to automate your tannery to the Dosemat DD.
In proven Dose quality, of course.
- iPControl system: control and monitoring of the entire production process
- Dosemix: The water mixing and dosing system ensures precise addition of water and chemicals.
- Chemdos system: Automatic dosing of up to 30 liquid components.
Jet-Cross-Flow-System
This is the most efficient fleet circulation system available.
Advantages:
- Uniform rinsing of the leather with chemicals and pigments
- Uniform liquor circulation
- Efficient emptying
- Time saving due to fast circulation and emptying

The Dosemat is similar to a large washing machine.
The larger the load, the more likely it is to become unbalanced when spinning.
The three-part drum reduces the risk of the load becoming concentrated and the spinning becoming uneven.
This allows 60 % more raw material to be fed into the machine.
More raw material means more production in the same time and in the same space in the tannery.
A great advantage where time and space are usually in short supply.

The large corporations in the luxury goods industry rely on leather from our machines.
Because the production of high-quality leather requires stable and reliable production.

Dividing the Dosemat DD into three sections reduces imbalances and allows 60% more raw material to be loaded.
Same space requirement in the tannery – significantly increased productivity.
